COLLEGE STATION – As temperatures reached 100 degrees and above, the stress on beef cattle increased, said Texas A&M AgriLife Extension Service experts.

Though there are no reports of large death losses yet, the stress does affect beef cattle health and certainly reduces their feed efficiency and daily gains, both on pastures and in the feedlots, the experts said.

“The really high temperatures we’ve had the last several weeks have caused cattle to undergo a lot of heat stress,” said Dr. Joe Paschal, AgriLife Extension livestock specialist, Corpus Christi. “Typically, cattle are going to shade up a lot more, particularly if they are black-hided rather than if they are of Bos indicus or Brahman influence.”

Paschal said in addition to staying in the shade much of the day rather than grazing, cattle are going to look for ways to cool off, such as standing in ponds or stock-water tanks.

If these measures aren’t enough, then they will start showing physiological signs of heat stress, he said. Cattle mainly cool themselves by panting. Bringing in cool, moist air will allow them to lower their core temperature, and by turn, their outer body by increasing the amount of blood to their hides.

“If they can bring cool air into their lungs, that’s fine, but they can’t now,” Paschal said. “They are bringing in air that’s at 100 degrees and at very low humidity, and it’s making them even hotter. This affects their entire metabolic process. It’s even harder on feedlot cattle as they’re fatter.”

Dr. Ted McCollum, AgriLife Extension beef cattle specialist, Amarillo, said it is true that feedlot cattle are more susceptible to heat stress. This is because they are generally fatter or “fleshier,” and the fat acts as an insulator, making it harder for them to dispel heat by convection.

However, he hasn’t heard that many reports on death loss this summer, he said.

Of the 120 or so feedlots that finish cattle in Texas, Oklahoma and eastern New Mexico, most are in the Texas Panhandle, McCollum said. And one of the several reasons that most confined cattle feeding units are there is because of the climate.

“The one thing about this part of Texas as compared to South Texas, or farther north in Nebraska where you hear about death losses from heat stress in feed yard cattle, is that we do cool down at night,” McCollum said.

The cooler nighttime air means cattle in Panhandle feed yards have the chance to “unload” that heat at night.

This isn’t to say that some cattle in Panhandle feed yards haven’t suffered health problems during the past several weeks, but to his knowledge there haven’t been any large-scale problems, he said.

Some performance losses have occurred because of reduced feed consumption during the hot weather. Digestive processes generate body heat. So in response to hot ambient temperatures, cattle will often reduce feed intake in an effort to reduce their heat load, he said.

AgriLife Extension district reporters compiled the following summaries:

The 12 Texas A&M AgriLife Extension Districts

Coastal Bend: Some parts of the region had not received rain for nearly four weeks. Others got a few scattered showers, but nothing significant. The dry conditions helped farmers get some crops harvested, but some had to irrigate soybeans and cotton. The dry weather was expected to reduce the yield potentials of soybeans and hay fields. Many producers were taking a second cutting of hay, but grass regrowth was slow to non-existent due to lack of topsoil moisture. The corn and grain harvests should be completed by the middle of August. Rice was starting to arrive at grain elevators. Livestock owners were checking water sources daily to assure all livestock had adequate water. Cattle were generally in good condition, but more calves were being shipped as forage supplies began to wane.

East: Most counties reported temperatures above 100 degrees, along with dry and windy conditions. All counties needed rain. Pasture and hay fields were showing drought stress. There was a general browning of all grasses, and a great reduction in regrowth. Producers who had overstocked their pastures were beginning to run out of grass. Soil moisture continued to dwindle. Most counties rated topsoil as short, with several rating it as very short. Burn bans were being issued throughout the region. Many Anderson County oak trees were dying. Vegetable harvesting was nearly over. Some truck farmers were preparing for fall planting. Pond and creek levels were dropping. Cattle were in good condition. Weaning and selling of market-ready calves and cull cows continued. Some producers were supplementing livestock with protein. Horn flies continued to be a problem. Feral hogs were on the move, rooting up pastures and lawns.

Far West: The entire region had temperatures well above 100 degrees. A few counties received measurable rainfall. Dryland cotton in Glasscock County was showing signs of heat and moisture stress. Cotton in most other counties was in good condition, at full bloom and setting bolls. Corn was in fair to good condition. Alfalfa growers were taking a fourth cutting. Pecans looked good. Sorghum crops were in fair condition. Pastures and rangeland were beginning to dry out but were in fair to good condition. Subsoil and topsoil moisture ranged from adequate to short. Cattle were generally in good condition. Calves and stocker cattle were gaining weight.

North: Temperatures reached 100 degrees every day. Topsoil moisture was short to very short. The ground was cracking in many places, and pastures were drying out very quickly. Producers continued to harvest Bermuda grass hay and annual forage sorghum. Corn and grain sorghum were maturing very quickly, with harvesting likely to begin in the next week or two. Yields of both crops were expected to be below average as both were planted late due to excessive rain during the spring and early summer. Soybeans were struggling with the heat. Sunflowers looked good in some areas but were stressed in others. Livestock were in good condition for August but were seeking refuge in stock tanks and waterways to stay cool. Flies and mosquitoes were abundant. Wild hogs continued to cause damage.

Panhandle: The region remained hot and humid, with temperatures near normal for early August. Isolated areas received showers, from a trace to 3 inches. Grasshoppers were a problem throughout the region. Spider mites were being monitored in Deaf Smith County corn fields, along with sugarcane aphids in Hansford and Lipscomb counties. In Collingsworth County, the hot weather added much needed heat units for cotton and sped up the maturing of grain sorghum. Irrigators were watering cotton while the crop was setting bolls. Deaf Smith County producers were evaluating damage from the past storms. Several corn, sorghum and wheat fields were totally lost. Otherwise, Deaf Smith County crops were generally in good shape, with much of the corn in the milk to early dough stage. Grain sorghum was coming along well too, with early planted fields setting seed. Cotton was struggling as many fields were behind and needed more heat units. Gra sshoppers were particularly bad in Deaf Smith County, with many producers having already sprayed multiple times in an effort to control the invasion. Producers were concerned about planting early wheat until the grasshopper problem was resolved. In Hall County, extremely hot weather stressed crops and livestock. Hansford County received another 1.7 to 2 inches of rain. Weeds were becoming a big problem in some fields. Corn looked great, and some irrigation pumps were turned off to allow cutting of silage. Irrigated and dryland sorghum looked great. Irrigated cotton also looked very good. Dryland cotton stands were spotty in places. Lipscomb County reported sugarcane aphid infestations in grain sorghum. Randall County crops continued to progress after some rain. Wheeler County cotton was still behind normal development.

Rolling Plains: Summer heat hit the region, with high temperatures ranging from 100 to 107 degrees. The heat rapidly dried out topsoils but was good for most cotton, though some fields were showing signs of stress. Summer annual forages were being harvested. There were reports of sugarcane aphids on grain sorghum. Cattle were in good condition, and pastures were holding up, though some grasses were drying out quickly. Grasshoppers were still damaging trees and crops, but populations were declining.

South: Very hot and dry conditions were the rule throughout the district, and soil moisture levels were dropping. In some areas, there had been no rain for as long as six weeks. In the northern part of the district, corn and sorghum harvesting continued. Peanut development ranged from the flowering stage to setting pods. Cotton was opening bolls. Pastures and rangeland were drying out, but they generally were still in fair shape. Some producers were baling hay. Body condition scores of cattle remained good. In the eastern part of the district, most pastures still looked good despite the lack of rain, but producers expected they will have to provide supplemental feed to livestock soon if there is no rain. The grain sorghum harvest was underway with some producers reporting yields of 5,000 pounds to 6,000 pounds per acre. Small fires broke out in rangeland and pastures in Jim Hogg County. Cotton growers did not expect harves ting to begin in earnest until Sept. 1. Soil moisture in the eastern counties ranged from adequate to short. In the western part of the district, the continuing hot, dry weather meant producers still had to irrigate cotton, pecans and some late-planted sorghum fields. The harvesting of corn and sorghum was active. The availability and quality of native rangeland and pastures grasses further declined. Producers who had heavy grazing pressure on native rangeland had to provide light supplemental feeding. Cotton was making good progress. In the south part of the district, soil moisture was short. Producers were defoliating cotton, and the sugarcane harvest was ramping up.

South Plains: Temperatures were in the triple digits, which for some counties was a first for the year. Cotton development ranged from just beginning to bloom, with eight nodes above white flower, to physiological cutout with five or fewer nodes above white flower. The heat was generally good for cotton in helping it somewhat catch up on development. Floyd County cotton started to set bolls, and grain crops continued to look great. Hale County received timely, scattered showers that provided significant moisture in a few areas. Cochran County also received showers that improved subsoil and topsoil moisture. Peanuts there were doing very well. Sugarcane aphids were confirmed in grain sorghum, while cotton was impacted by fleahoppers and lygus bugs during the last few weeks. Lubbock County recorded its first official 100-degree day on Aug. 6. However, temperatures had been consistently near 100 for days, with higher than normal humidity. Spotty rain showers amounted to 0.5 to 1 inch of moisture. Cotton was stressed where no rain was received. Grain sorghum producers were closely monitoring widespread sugarcane aphid infestations. Some fields reached economic threshold levels for treatment. Garza County also received rain, from a trace to as much as 2 inches. Cotton continued to progress but needed rain to maintain development. Mitchell County had several 100-degree days. Rangeland condition declined, and the increased chances of wildfire became a concern.

Southeast: Soil moisture varied widely throughout the region, but was mostly in the adequate to short range, with short being the most common. Rangeland and pastures were mostly rated in fair to poor condition, with fair ratings being the most common. Temperatures were at or above 100 degrees. Soils and lowland areas were drying out. Pasture conditions were beginning to fade. In some areas, there had been no regrowth of grass after the first cutting of hay about three weeks ago. Corn was drying down very quickly. In Chambers County, early rice that did not have to be replanted was being harvested. Dry conditions made draining rice fields a hard decision, but the alternative was to chance plants dying and lodging. In Fort Bend County, the grain sorghum harvest was mostly finished. Yields ranged from 3,500 pounds to as much as 7,500 pounds per acre. The corn harvest began, with yields ranging from less than 100 bushels to as muc h as 240 bushels per acre. Cotton was progressing quickly, and some producers expected to begin defoliating within a week. Livestock were in fair to good condition.

Southwest: Hot, dry conditions persisted throughout the region with no rain reported. Temperatures have been in the high 90s to over 100 for weeks, which was cooking grasses and forbs. Burn bans were instituted in some counties. The grain sorghum harvest neared completion, and the corn harvest was in full swing. Pasture conditions continue to decline with hot and dry conditions. Hay yields have been very high, but most fields were already going to seed or becoming dormant. Cotton was doing well. Wildlife generally were in good condition. With pastures declining, due to the hot weather, livestock were showing signs of stress.

West Central: The region had triple-digit temperatures with no rain forecast. The continued hot, dry, windy conditions were drying out soils, pastures and stock-water tanks. Row crops were showing signs of heat and moisture stress. Some producers were preparing fields for fall planting, but many were waiting for a rain before beginning. The danger of wildfire was high and increasing every day. Cotton was maturing fast thanks to the hot days and warm nights. The grain sorghum harvest began. Hay harvesting continued, with many producers taking a second cutting. Some expected to get a third cutting. Grasshoppers were becoming an issue in some areas, and producers were applying pesticides. Rangeland and pastures remained in fair to good condition, but were beginning to show signs of stress. Livestock remained in fair to good condition. Calf weaning continued.

Tumble Windmillgrass

Published

on

By

By Tony Dean

Tumble windmillgrass is a short, compact perennial bunch grass that is adapted to almost every corner of Texas.  It can grow on almost any soil, but prefers coarse textured soils. 

The most obvious characteristic about Tumble windmill is its large seed head sporting 10 to 16 laterally spreading branches, each approximately two to six inches long, arranged in one to three whorls.

When mature, the seed head will break off and be caught up in the wind, making Tumble windmill one of the great wanderers of the plains.  It can tumble great distances, spreading itself in the process.  This wanderer seems to like parking in your garage on windy days, as well as dancing around windy corners of buildings and any other place the wind decides to carry it.

Tumble windmill can also spread by short stolons.  The upper leaves are very short, while the lower leaves are often much longer. The leaves are light green with a purplish seed head that fades to pale reddish at maturity.

Tumble windmillgrass provides poor forage for livestock and wildlife, although most grazers will use the forage in early spring when tender.

Since Tumble windmill can grow in poor soil conditions, it is useful as a component for a prairie grass mix used on disturbed areas. This grass does not usually dominate a pasture but can often be found in smaller amounts.  Proper grazing use along with rotational grazing can cause the plant to be replaced with higher successional plants.

Looking for Low-Maintenance Poultry? Geese are Your Answer!

Published

By

Unless you are a fan of Dickens and Doyle, geese probably aren’t the first thing that comes to mind when you think of poultry. But maybe they should be. And the aim of this article is to get you acquainted with the aristocrat of poultry.

Let’s start with the basics. Geese are domesticated waterfowl. Twelve breeds are recognized by the American Poultry Association, but dozens more are available. Much like ducks, all domestic geese breeds descend from two species. The overwhelming majority of breeds originate from Greylag geese (Anser anser). This species is native to Europe and Central Asia. These are the stockier, heavy geese that feature prominently in German fairy tales as a symbol of wealth and which Victorians loved to consume at Christmas. These geese come in various sizes, colors and dispositions. Here are a few examples: Cotton Patch geese are a small, variably-colored, extremely heat tolerant landrace native to the South. These were raised to consume weeds in cotton fields in the days before commercial herbicides. They are quite rare today and lay a variable number of eggs. American Buff geese are medium-sized, tan colored, very docile geese of uncertain origin. They are excellent meat birds. They are decent layers and wonderful mothers. Toulouse geese are the largest breed at up to thirty pounds. This ancient French breed is dark grey in color. They are bred to become very fat and so must be managed carefully to maintain fertility. They are very gentle, but require somewhat more shelter than other breeds.

A native of parts of China, Mongolia and Russia, the Swan Goose (Anser cygnoides) gave us both the Chinese goose and the African goose. Both have large bulbs on their heads and are similarly colored, but are otherwise very different. African geese are quite large, maturing at around twenty pounds and prized for their meat. These gentle giants are often recommended for beginners. Chinese geese are the egg champions of the goose family. They produce multiple clutches in a year, equaling up to a hundred eggs annually. They are small geese with males weighing about twelve pounds and females ten. They are nervous and the loudest breed, but this makes them suburb as “watch geese” and perhaps the best all-purpose breed.

Now that we are a bit acquainted with various breeds, we can find out just why someone may want to keep geese. Before we go over their benefits, you may be surprised to learn something surprising about geese. Geese are so rarely seen in the United States today that they can seem unusual, even exotic. As such, you may reasonably expect that geese are hard to manage, require expensive feeds and must be waited on hand and foot. The surprise is that geese are actually significantly easier to take care of than chickens. In fact, I would venture to day that geese are the lowest maintenance poultry there are.

Geese are unique among poultry in that the vast majority of their diet is made up of grass. Some meat birds are raised entirely on grass. It may be a good idea to supplement their grass with some chicken feed and scratch grains, but you will find that, when grass is plentiful, they will generally not bother with anything else. Geese are excellent pasture birds. A simple wire pen that can be moved every other day is enough to keep them happy. Unlike chickens, geese do not scratch up a yard and are not nearly as messy as ducks. If moved promptly, the area they occupied will swiftly grow back greener, thanks to all the free fertilizer, which they produce in abundance. Few geese can fly with any proficiency and even then, only when they are young. One wing’s feathers can be easily clipped, if their escape is a concern.

Geese are also almost absurdly hardy. They not only love rain, they seldom if ever go inside. Shade and perhaps a windbreak are their only real needs for shelter. In sub-freezing temperatures, they will scorn a shed and simply sit in the snow. There is a reason that goose down is so valued for comforters. It is extremely good at keeping them warm. The clever little birds know exactly when they need to bend down over their feet to keep them warm and hide their heads under their wings for the same purpose. In the summer, geese require shade and access to water at all times, but are otherwise unbothered. Geese keep their bodies very clean and are, owing to a small oil gland and their meticulous grooming, waterproof. They will soil water almost instantly, so do not worry about keeping it clean, just be sure they have enough. Without water, they may die in the heat and regardless (like ducks) cannot keep their bills and eyes clean, which could cause disease. Provide multiple water tubs to reduce fighting. Geese will dig up the mud around their waterers, so they should be moved each time they are filled. They will appear to be eating the mud, but are actually filtering it in the water through the serration in their bills. This is to find food, as well as small rocks for their gizzards. With a bit of caution, geese will weed a garden for you and clean it up at the end of the season.

Geese need little more from you than water, basic protection from predators and grass. In return, they offer a number of benefits.

In the first place, Geese offer a dark, rich, beef-like meat. Geese are often butchered between twelve and twenty weeks old. At this time, their weight will vary by breed, but as an example, the commonly raised meat breed Pilgrim geese will weigh around thirteen pounds. The carcass weight will be about sixty to seventy percent of the live weight. If one cares to process it, goose fat is highly valued in the culinary world and contains almost no saturated fat. It is comparable to olive oil and may be used in the same applications.

Especially if you have selected the Chinese goose, eggs are another offering of your new favorite poultry. These eggs are roughly the equivalent of three chicken eggs. A fried goose egg, sausage or bacon and a pancake makes a very nice dinner or hearty breakfast. Alternatively, you can incubate and hatch goose eggs quite easily. The goslings are so valuable that it’s a wiser financial move to only consume the first couple of eggs laid in the spring, which are usually infertile. Goose eggs are easily candled without any special equipment. Infertile eggs or those that die early on can be blown out and made into painted or dyed eggs.

If you hate waste, and wish to use all but the “honk,” so to speak, the feet are rich in collagen and highly prized in the rest of the world. The liver of a goose is extremely healthy and famous as foie gras. A more familiar byproduct of butchering is down, which can be made into extremely valuable bedding. Be sure to clean and dry feathers carefully first. If raised by hand and handled very often, geese will be quite friendly to their owners and make loyal pets. Some people will actually hold their geese in their laps and gently pluck the down from their flock.

Lastly, geese are often kept as watch animals. Geese are extremely observant night and day and will loudly complain when they see something unfamiliar anywhere in the vicinity. It takes a very short time to learn the difference between the normal sounds of geese and the sound of their panic. Please know that while they may scare away small predators and they are nearly always too big for hawks, a goose is largely defenseless against most predators. Keeping geese near a livestock guardian dog is a great idea. The extremely intelligent birds will rapidly learn the dogs are a source of safety and will alert the dogs to anything they see as a threat. Geese can usually be kept with other poultry without problems. They will not directly protect their avian brethren, but the others will learn to hide when the more observant geese voice a concern. In mixed flocks, the noble geese stride around the yard, aristocracy among poultry.

Geese are immensely versatile, the most low-maintenance poultry there is and should have a place on any property.

Changing the Way We Handle Hay

Published

By

Few machines have reshaped livestock operations as much as the round baler. Before its arrival, haymaking was slow, labor-intensive, and limited by the storage and handling of small square bales. The round baler mechanized the process, producing large rolls that could be handled with tractors instead of back-breaking labor. Today, those big bales are a familiar sight across Oklahoma, Texas, and much of the world, stacked along fence lines or dotting pastures.

The modern round baler traces back to the mid-20th century. While early versions of hay-rolling machines appeared in Europe in the 1940s and 1950s, it was a man from Iowa who brought the design into practical use in America. In 1971, Vermeer Corporation, led by Gary Vermeer, introduced the first large round baler that could be mass-produced and widely adopted. His design gathered hay into a chamber, rolled it into a tight cylindrical package, and then wrapped it with twine before ejecting it onto the ground.

This solved a long-standing bottleneck. Small square bales required enormous labor — lifting, stacking, hauling, and feeding by hand. One person with a tractor and round baler could do in hours what once took a crew all day. The new bales were weather-resistant, stored easily outdoors, and reduced spoilage. They also fit well with the larger scale of modern cattle operations.

By the 1980s, other manufacturers such as John Deere, New Holland, and Case IH offered their own models. Improvements included variable chamber sizes, better pickup systems, and stronger tying methods. Round balers quickly became the standard for beef and dairy producers in Oklahoma, Texas, and beyond.

Though models vary, the principle remains the same. The baler picks up cut hay from the windrow and feeds it into a chamber with belts, rollers, or chains. As the hay circulates, it rolls into a tight cylinder. Once the bale reaches the set size — often 4×5 or 5×6 feet, weighing between 800 and 1,200 pounds — the machine stops feeding, and the bale is wrapped for storage.

The result is a dense, weather-resistant package that can be moved with a tractor spear or loader. Unlike small square bales that require dry storage, round bales can be stacked outdoors, especially when wrapped correctly.

The biggest evolution in round baling since its invention has been the way bales are bound. Early machines used only twine, usually sisal or synthetic. Twine is inexpensive and reliable, but it has drawbacks. Wrapping a bale with twine can take up to two minutes, slowing production. Twine also leaves more exposed surface area, allowing moisture to penetrate and spoil hay.

Net wrap was introduced in the 1990s as a solution. Made of high-strength polyethylene, it wraps the bale quickly — usually in 10 to 20 seconds — and covers more surface area. This tighter, more uniform wrap sheds water better and reduces spoilage, especially for bales stored outside. Net-wrapped bales also hold their shape better, making them easier to stack and transport.

Producers must weigh cost against efficiency. Net wrap is more expensive than twine, both in material and in required equipment, but many ranchers find the savings in time and hay quality worth the investment. Twine remains common for operations feeding hay quickly or storing it under cover, while net wrap dominates in large-scale or commercial setups.

In recent years, bale film wrap has also entered the market. Similar to plastic used in silage, film wrap can seal bales almost completely, reducing spoilage even further. While more expensive, it is gaining ground in wet climates and dairies where feed quality is critical.

The round baler is more than a machine — it changed the rhythm of haymaking. Producers can now harvest, bale, and store hundreds of tons of hay with a fraction of the labor once required. In regions like Oklahoma and North Texas, where cattle herds are large and hay is often stored outdoors, round balers became indispensable.

The machine also influenced land use. With the ability to bale quickly and efficiently, ranchers could harvest larger fields and manage forage with precision. It also reduced dependence on hired labor during peak hay season, a major benefit as rural populations declined.

While square balers still have their place — especially for horse hay and small-scale operations — round bales remain the workhorse of modern cattle ranching.

From its introduction in the 1970s to its widespread adoption today, the round baler has proven to be one of the most influential farm inventions of the last century. It solved the labor bottleneck of haymaking, improved storage and feed efficiency, and fit seamlessly into the mechanization of modern agriculture.

Whether wrapped in twine, net, or film, those big round bales are more than just scenery on a country road. They are symbols of an innovation that continues to save time, labor, and feed across ranch country. Like the steel plow, barbed wire, and windmill, the round baler is an invention that permanently changed the way we work the land.
