What to expect when your cow’s expecting

Published

on

Overweight cattle and cattle turned out on lush legumes with high concentration are at risk as well. In this case, an epidural anesthetic is usually necessary. The tissue will need to be replaced and sutured in place. Vaginal sutures will need to be removed prior to calving.

Toxemia happens when cattle are exposed to low nutrition during the last two months of pregnancy. Cows that are overly fat and/or carrying twins are at higher risk. Cows with toxemia become depressed, stop eating and often stand off away from the herd. You will notice some have the scent of acetone on their breath. As the condition worsens, the cow may develop muscle tremors. Treatment for toxemia is IV glucose, B vitamins or propylene glycol given by oral drench.

During calving there are a number of problems that could occur. Those include dystocia, bruises and lacerations to the birth canal, uterine prolapse, milk fever, retained placenta and grass tetany.

            According to the Beef Cattle Handbook, a product of Extension Beef Cattle Resource Committee Adapted from the Cattle Producer’s Library, at any time a cow is unable to deliver her calf, a dystocia has occurred. There are many things a producer can do to reduce this incidence. With heifers, lot those with small pelvic areas before breeding. Select bulls based on their birth weight, not on their relative size. Ultimately use bulls that will produce small birth-weight calves. When calving first-calf heifers separate them from cows, at best into small groups. Producers will want to provide surveillance over the heifers on a 24 hour basis. Some tips include restricting the calving to 42 to 60 days. That will enable personal focus for a short, intense calving period. Also feeding at night between 9 and 11 p.m. will cause more animals to calve during daylight hours.

            If problems arise and a cow hasn’t shown progress in 60 to 90 minutes, it’s time for the producers to step in. Signs of an abnormal delivery are the head only, the head and one leg, one leg alone or the tail. At this point it is best to contain the animal in a squeeze chute or small pen. A calf can only deliver one of two ways: both front feet followed by the head or both back feet out together. Once constrained, using ample lubrication, a producer can reach in and move the calf to one of the two correct positions. If unable to do so, a veterinarian should be called. The top problems include not getting the head out with front feet, having a calf too big to deliver through the mother’s birth canal resulting in hip lock and abnormal breach in which the tail is the only part of the calf visible through the vulva. If all goes well and pulling the calf is suggested, direct traction down and away from the birth canal. Do not pull straight out behind the cow. If two men are unable to pull the calf using the OB chains or when using the calf puller, do not use excessive force. It will not deliver the calf. Odds are the cows birth canal is too small for the calf and will result in a c-section.

            Keep in mind bruises, lacerations and rupture of the birth canal are possible during a difficult birth. Rough handling of the calf or maternal tissues and careless use of obstetrical instruments during calving add danger. This is typical when a cow is in labor several hours with a dry, non-lubricated birth canal.

Cows with difficult delivery and trauma to the tissue and birth canal may have damage to the nerves and spinal cord or hips that supply the legs. This results in abnormal leg function. In some cases, while pulling a calf, excessive force was used and the middle lower pelvis bones were fractured. At this point steroids are administered to help with swelling and nerve healing. In bad cases were the cows are unable to stand, they need to be hoisted to their feet twice a day.

            In older cows producers may see difficulty in birth injury or irritation of the external birth canal and severe straining, retained placenta and loose uterine attachment in the abdominal cavity called uterine prolapse. When noticed, this condition needs immediate action. Apply material to uterine wall to saturate fluid ASAP. You can use sulfaurea powder, urea powder or even sugar. Replace the uterus immediately or call your veterinarian. Without properly replacing the uterine horns, prolapse will reoccur.

            Usually the placenta is passed in three to eight hours. If the placenta hasn’t passed in eight to 12 hours of calving, the placenta is retained and the cows must be treated. A number of reasons lead to retained placenta: dystocia, c-sections, fetotomy, twinning or abortion along with other infectious diseases. Even feed deficiencies, malnutrition, low carotene, vitamin A, iodine, selenium and vitamin E can be to blame. To treat, use slight, manual force and gently pull on the placenta. If it resists, stop and pack the uterus with boluses or fluid douches to keep antibiotics in the uterus. As with prolapse, be sure to use proper hygiene when treating the uterus or worse problems will occur.

            Another condition parallel with cows with age, number of calves and dairy or mixed breeds is milk fever. This condition happens when a cow starting to produce milk is unable to remove calcium from her bones quickly enough. If blood levels of calcium fall below the minimal level, the muscles of the body are unable to function. This leaves the cow almost crippled, comatose and dead. High blood levels of estrogen inhibit calcium mobilization; this may be a factor on pastures that are high in legumes. Usually a slow administer of IV calcium is given. 300 to 500 ml of a commercial calcium solution is given over 20 to 30 minutes.

             Lastly, grass tetany poses as an issue to cows calving. It is similar to milk fever, but in this instance cattle have heavy post-calving lactation and lose large amounts of magnesium in their milk. Most types of mixed pasture grasses are low in magnesium. If cows are exposed to cold weather or stress during early lactation, their blood levels may drop low enough to cause grass tetany. At that point an IV of magnesium is given with calcium. Treatment is not as effective as with milk fever and in many cases, animals do not respond.

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.
