Beef AG NEWS: Developing a Mating System for Beef Cattle

With more than 70 recognized beef cattle breeds in the U.S. it can be difficult to decide exactly which breed or combination of breeds work best in any given situation. In this broadcast, John Grimes and Duane Rigsby discuss considerations for choosing the beef breed or breeds that can best accomplish the breeding and marketing goals of the individual cattleman.

Beef AG NEWS: Tools for Genetic Improvement in Beef Cattle

In this broadcast of the Beef AG NEWS, John Grimes and Duane Rigsby discuss how EPDs, genomics, genomic enhanced EPDs and selection indexes can be utilized for the selection of individual animals that best fit the criteria for your beef herd mating system.

Genetic Markers and Their Use in Feedlot Cattle

Steve Boyles, OSU Extension Beef Specialist

Carcass characteristics are economically important but can be difficult to measure pre-harvest. Therefore, genetic markers associated with these traits may provide valuable information to decision makers. The success of genetic markers depends on the accuracy of molecular breeding values (MBV). Researchers at Oklahoma State University evaluated molecular breeding values for yield and quality grades for commercial beef cattle and reported it in their publication:

Independent validations report significant correlations between molecular breeding values and the traits they predict. However, many of these molecular breeding values explain Continue reading

Beef AG NEWS: Considerations for Selecting your Next Herd Sire

With calving season in full swing throughout much of Ohio, breeding season is right around the corner. That means bull buying season is here.

In this edition of Beef AG NEWS, show host Duane Rigsby visits with OSU Extension Beef Coordinator John Grimes about herd sire selection considerations including everything from selecting a breeder to work with, to the specifics of actually selecting the bull you ultimately choose to purchase.

Bull Buying Tips

– Dr. Darrh Bullock, Extension Professor, University of Kentucky

We are rapidly approaching bull buying season in Kentucky so there are few basics I would like to share. The genetics in the bull you are buying now will have a huge impact on your herd immediately and could linger for years to come if you keep replacements from him. For this reason it is important to get this decision right.

For commercial cattlemen, the first suggestion is to evaluate your crossbreeding program and make sure you are taking full advantage of heterosis (hybrid vigor). If your cow herd is made up of predominantly one breed then you might consider introducing a second breed and start a rotation system with those breeds. This can improve the productivity of your herd by greater than Continue reading

Time to Step Up Your Game

John F. Grimes, OSU Extension Beef Coordinator (originally published in the Winter issue of The Ohio Cattleman)

Nearly every business is faced with evolving business models due to changing consumer preferences. History provides us plenty of examples of how traditionally accepted products or services can quickly be replaced by a newer or “better” version. Some call this progress while others prefer simpler, more traditional choices.

The beef industry is certainly no stranger to the concept of changing types and preferences. The size and shape of cattle have changed significantly over the years of modern history. The smaller framed British breed cattle prevalent in the 1950’s and 1960’s were forever changed by an influx of Continental breeds staring around the beginning of the 1970’s. This started a trend towards larger framed, growthy, leaner cattle that were very popular through the 1980’s and into the early 1990’s. The past 20-25 years have seen a trend towards Continue reading

Is Your Herd Focused on Meeting Demand?

Stan Smith, OSU Extension PA, Fairfield County (originally published in The Ohio Farmer on-line)

Despite the higher price, consumers want quality, and are willing to pay for it!

To say the least, suggesting it’s been a wild ride on the path to profitability in the cow-calf sector during this decade is an understatement. Beginning in 2009-10 cattlemen saw the most dramatic increase in cattle prices ever. From there prices climbed to the point where we experienced historic highs just four years later. As would be expected, at the same time consumers were experiencing historic high beef prices in the meat case.

What might not have been expected was that while lower overall beef supplies were causing these historically high live cattle and retail meat prices, demand by consumers for premium priced branded beef continued to climb Continue reading

Changes in Carcass Grade Over Time

– Andrew P. Griffith, University Of Tennessee (previously published by Drovers online)

The beef industry, similar to other industries, is constantly attempting to be more efficient and create more value in the product produced. Most cow-calf producers concern themselves with reproductive efficiencies and pounds of weaned calf per acre of land. These two things are important because a cow-calf producer cannot afford to have very many cows fail to wean a calf, and these producers are in the business of selling pounds with a limited quantity of land. Similarly, stocker producers work to reduce morbidity and mortality rates while also trying to pack on as many pounds as possible with their forage and feed resources. Producers from both of these sectors also attempt to add value by instituting management practices that reduce risk to downstream cattle buyers.

The feedlot perspective is very similar to stocker and backgrounding operations with focus on feed efficiency and cattle health, but there is also interest in carcass characteristics. Regardless of the marketing method (cash, formula, grid, etc.), cattle will be priced based on the actual or expected yield grade (YG 1-5) and quality grade (Prime, Choice, Select, etc.).

Quality grade and yield grade are two aspects of beef production that may or may not be considered at the cow-calf and stocker producer levels. There are certainly Continue reading

The Effect of Cow Udder Score on Calf Performance

Steve Boyles, OSU Extension Beef Specialist

Nebraska research shows hot carcass weights were lighter from bad uddered cows.

Scientists at the University of Nebraska (J. Beard, J. Musgrave, R. Funston and J. Mulliniks) used 812 cows and their udder scores to evaluate calf performance. Udders scores were recorded from a 1 (bad) to 5 (good) as reported in the Integrated Resource Management Guide (National Cattlemen’s Beef Association). They then separated the data into 2 groups of Bad Udders (1 and 2 scores) and Good Udders (3 or greater scores). There were 233 cows with Bad Udders and 1,742 cows with Good udders.

There was not a difference in Continue reading
