VERNON – The past El Nino autumn and winter offered a good opportunity to establish pastures of summer-dormant tall fescue in Texas and Oklahoma, according to Dr. Dariusz Malinowski, a Texas A&M AgriLife Research forage agronomist and plant breeder in Vernon.

“A number of producers inquired about the availability of summer-dormant tall fescue seed last summer, and these producers had luck with stand establishment last autumn,” Malinowski said. “The first growing season is the most critical to establish summer-dormant tall fescue pasture, and it looks like the weather has been cooperating so far.”

For more than 10 years, he has been researching and evaluating a number of cool-season grasses originating from the Mediterranean Basin in environments with harsh summer droughts and mild winters, resembling Texas climate conditions.

These grass ecotypes possess a summer dormancy trait that allows them to survive six months without precipitation, in blistering heat, Malinowski said.

“There is no doubt in my opinion that summer-dormant cool-season grasses will be the only option for cool-season perennial forage for a long time, considering the climate projections for the Southern Great Plains.”

He said climate change is projected to progress in the U.S. in the next couple of decades. The U.S. Global Change Research Program report predicts by the end of the century, the average U.S. temperature may increase by 4-6 degrees under the lower greenhouse gas emissions scenario or by 7-10 degrees under the higher emissions scenario.

Climate models suggest much of the Southeast and Southwest will become drier, especially in winter and spring, resulting in increased drought severity and duration, he said.

“These changes began taking place in Texas in the mid to late 1990’s and have been progressing ever since,” Malinowski said. “We all remember the devastating drought of 2011 in the Southern Great Plains, and 2015 had the highest average temperature ever recorded.”

Producers rely on cool-season forages to sustain millions of grazing cattle each winter in this region, with wheat the major source of high-quality forage, he said. But abrupt patterns of autumn precipitation occurred quite often in the past years, delaying wheat planting and resulting in a lack of sufficient forage production.

“Producers are increasingly interested in planting perennial cool-season pastures that may serve as a complementary forage source to wheat or replace wheat grazing systems and balance the effects of weather extremes,” Malinowski said.

Unfortunately, he said, most of the traditionally planted cool-season perennial forage grasses are now history in Texas and most of the Southern Great Plains because of their inability to cope with progressing aridity.

“We took the climate change predictions very seriously in the early 2000s, when I started to lead the forage systems program at Vernon,” Malinowski said.

“Consequently, we initiated a collaborative research with Grasslands Innovation of New Zealand in 2008 to breed new cultivars of summer-dormant tall fescue, orchardgrass and perennial ryegrass with improved forage productivity and quality, and superior persistence.”

He said several breeding lines are in the final stages of cultivar development and will be available to producers in the next few years.

Developing a new forage grass cultivar is not a fast track achievement.

“Similar to wheat, it takes about eight to 10 years to accomplish this goal,” Malinowski said.

Meanwhile, producers have had a choice of two commercial cultivars of summer-dormant tall fescue in the U.S. – Flecha by Grasslands Innovation and Prosper by Barenbrug USA. In the past years, these cultivars were planted across Texas and Oklahoma and persisted well until the historic drought of 2011, he said.

“Repeated lack of precipitation during several subsequent winter growing seasons and the resulting inability to replenish resources exhausted the grass plants beyond their level of tolerance,” Malinowski said.

There has been some concern the introduction of summer-dormant cool-season grasses to environments of the Southern Great Plains and the Mediterranean environments of California may result in these species becoming invasive to native flora, as was the case with summer-active tall fescue introduced to the U.S. in the 1800s, he said.

“Summer-dormant cool-season grasses, tall fescue in particular, are genetically and physiologically distinct from the summer-active variants; thus their potential to be invasive is not similar,” Malinowski said.

Preliminary research suggests summer-dormant grasses originating from the Mediterranean Basin and introduced to Mediterranean-like environments of California have very limited potential for invasiveness when compared with introduced Mediterranean annuals and native summer-dormant grasses.

“Our data show that summer-dormant tall fescue is less competitive than continental tall fescue when both types were grown in binary mixtures with alfalfa, especially when constrained by low soil moisture availability in summer,” he said.

In non-native environments such as those of the Southern Great Plains, summer-dormant tall fescue will not be able to take advantage of summer soil moisture, in contrast to native temperate and warm-season flora, because its growth pattern is highly restricted, Malinowski said.

“Summer-dormant cool-season grasses were introduced to southern Australia about 50 years ago and did not develop into environmental weeds,” he said.

Malinowski said many producers also want to incorporate a forage legume crop to grow with summer-dormant tall fescue.

“In collaboration with Dr. Twain Butler of the Samuel Roberts Noble Foundation in Ardmore, Oklahoma, we evaluated the compatibility of a range of forage legumes, including alfalfa and annual medics. Annual medics, having a very similar growth pattern to summer-dormant tall fescue, were the most suitable to grow in mixed stands with summer-dormant tall fescue,” he said.

Producers interested in growing summer-dormant tall fescue should contact their local Texas A&M AgriLife Extension Service agent or Malinowski at 940-552-9941, ext. 240.

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

on

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

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.
