The forage cattle consume as the bulk of their diet is often deficient in trace mineral concentrations. Cattle producers can choose from a number of different methods to provide supplemental trace minerals to cattle. This 3-page document discusses several common ways to provide trace mineral supplements as well as their advantages and disadvantages. Written by Matt Hersom and Todd Thrift, and published by the UF/IFAS Department of Animal Sciences, October 2018.
Body condition score (BCS) is both a good indicator of the past nutritional status of a cow and a way to determine future nutritional needs. The BCS technique is easy to learn and can help with management decisions. This new 5-page fact sheet discusses reasons to measure BCS, ways to evaluate BCS, and important assessment times. Written by Matt Hersom and Todd Thrift, and published by the UF/IFAS Department of Animal Sciences, August 2018.
Everyone likes a good bargain, but when it comes to hay, low price often equates to low nutritional value. Because hay is often sold on a large round-bale basis, savings from the good bargain can decrease substantially if there is a negative impact on the cow herd nutritional program. This 4-page fact sheet discusses intake limitations, energy limitations, protein limitations, examples of hay quality, and bad hay’s impact on cow body condition. Written by Matt Hersom and Todd Thrift, and published by the UF/IFAS Department of Animal Sciences, February 2018.
The dimensions of large round bales make a difference in many cases. Bale size determines the amount of hay in a purchased bale, the amount of nutrients in pounds, and the extent of spoilage during storage and feeding. Large round bales, the predominant form of hay made and fed to cattle, are under discussion. This 3-page fact sheet is a new document that examines the significance of bale dimensions, volume, density, and weight as well as the relationship of these factors to hay prices. Written by Matt Hersom, Todd Thrift, and Joel Yelich, and published by the UF Department of Animal Sciences, June 2016.
The Veterinary Feed Directive is a federal regulation from the Food and Drug Administration that will change the additives that can be included in animal feed, the ways in which cattle producers manage their animals and veterinarians interact with cattle owners, and the products available for use on the ranch. This 3-page fact sheet provides an overview of the new regulation’s nature, functions, requirements, and implications for cattle owners. Written by Matt Hersom, Todd Thrift, and Joel Yelich, and published by the UF Department of Animal Sciences, July 2016.
Culling decisions are important to maintain the productivity and profitability of the beef cow herd. Culling of cows from the herd eliminates poorly performing cows, inferior genetics, and cows with quality defects that would limit short- and long-term productivity. This 4-page fact sheet discusses reasons to cull as well as replacement of culled cows. Written by Matt Hersom, Todd Thrift, and Joel Yelich, and published by the UF Department of Animal Sciences, December 2015.
Shrink in beef cattle is weight loss that occurs between an animal’s departure from one location and weigh-in at another. Shrink in beef calves constitutes a potential economic loss to both the seller and the buyer if it is not fully considered. This 3-page fact sheet discusses factors that affect shrink and the effects of shrink on calf price. Written by Matt Hersom, Todd Thrift, and Joel Yelich, and published by the UF Department of Animal Sciences, December 2015.
Body condition score (BCS) indicates how much fat a cow has on its body, which is an important factor in cow health and reproductive capacity. Growers can use BCS to understand and manage the health of a herd and maintain a profitable operation. This 6-page fact sheet explains how BCS is measured, what different scores mean, the economic impact of various scores, and how changing cow nutrition can move BCS in a desired direction. Written by Matt Hersom, Todd Thrift, and Joel Yelich, and published by the UF Department of Animal Sciences, September 2015.
Getting cattle to put on a lot of muscle quickly is a crucial part of a beef cattle operation’s profitability. Growth promoting implants are one of the most cost-effective ways of increasing lean tissue in cattle and work by releasing hormones into the cow’s body that encourage muscle growth. This 4-page fact sheet explains implants’ mechanisms of action, how implants are administered and used, and concerns associated with implants. Written by Matt Hersom and Todd Thrift, and published by the UF Department of Animal Sciences, August 2015.
Cull cattle are those that are sold from a herd for lack of performance, lack of resources, or genetic improvement The non-fed beef cattle market (cattle that are not managed through traditional feedlot finishing systems) is comprised primarily of cull cows and bulls. To address liability and food safety concerns, this series of articles discusses some quality defects identified in the non-fed beef market, how to prevent them, and how to address them when they appear in cattle.
The South’s climate is appealing for equestrian activities. While riders enjoy the weather, it creates some challenges in caring for saddles and other tack. When the weather becomes hot and the humidity climbs and the rains are frequent, a tack room can become a breeding ground for mold and mildew. There are several things a rider can do, however, to lower the incidence of mildew on saddles and tack. This 3-page fact sheet was written by Joel McQuagge, Todd Thrift, and Ed Johnson, and published by the UF Department of Animal Sciences, November 2014. (Photo credit: Joel McQuagge, UF/IFAS)
This 4-page fact sheet discusses the purpose of castration in male calves as well as the different methods used to castrate. Most methods of castration cause a certain amount of pain and stress for calves, which can affect calf performance. UF/IFAS researchers recently tested different methods of castration in calves to determine the effects of each method on calf health and performance. This publication presents these results. Written by Trey Warnock, Matt Hersom, and Todd Thrift, and published by the UF Department of Animal Sciences, December 2013.
A study in Florida was conducted to examine the issue of age at castration to determine if castration timing resulted in significant differences in growth rate and weaning weight in nursing calves. In addition, the study included a comparison between Angus and Brangus calves in the treatment groups to determine if there was a breed by castration effect. No differences in calf growth rates were observed in early compared to late castration. This 4-page fact sheet was written by Amie Imler, Todd Thrift, Matt Hersom, and Joel Yelich, and published by the UF Department of Animal Sciences, March 2013.
Beef cattle producers should consider using ionophores to increase calf gain and gain efficiency in a cost-effective manner. Ionophores are feed additives used in cattle diets to increase feed efficiency and body weight gain. They are compounds that alter rumen fermentation patterns. Ionophores can be fed to any class of cattle and can be used in any segment of the beef cattle industry. Similar to many other feed additives, ionophores are fed in very small amounts and supplied via another feedstuff as carrier for intake. Ionophores decrease incidence of coccidiosis, bloat, and acidosis in cattle. This 4-page fact sheet was written by Matt Hersom and Todd Thrift, and published by the UF Department of Animal Sciences, December 2012.
There are differences between the real and perceived reasons that cattle buyers discount calves; cattle producers can control some reasons for price differentials, but they cannot control all of them. This 4-page fact sheet will review some of the attributes that affect market calf price and overall value. Written by Matt Hersom and Todd Thrift, and published by the UF Department of Animal Science, May 2012.
Florida’s climate makes conserving forages for later feeding challenging. Traditional hay harvest systems require optimal cutting, drying, and baling weather conditions. The use of round bale silage overcomes several of the challenges to hay production in Florida and offer an attractive compliment to traditional hay harvest systems. Learn more in this 6-page fact sheet written by Matt Hersom, Todd Thrift, and Joel Yelich, and published by the UF Department of Animal Science, August 2011. (Photo: Thomas Wright, UF/IFAS)
