Determining an equitable price for purchased forages is a necessary but often uncomfortable topic of discussion for feed growers and purchasers. Usually this discussion is in the context of corn silage; however, the same principles can be used in any discussion involving hay, baleage or grains. In order for an input market to be efficient, the price agreed upon by both buyers and sellers should adequately compensate the producer while still allowing the purchaser the opportunity to economically use the input.

The number of calves sold is a major source of income from a cow/calf operation. A high percent calf crop increases profit. Reproductive efficiency is the first factor to consider in a breeding program. A beef cow must conceive in the first 40 to 60 days of the breeding season, have a live calf unassisted, breed back to calve every 12 months, and raise a calf that is heavy enough to be profitable. To accomplish this, she must be managed correctly.

Genomic testing is not a new idea in the eyes of science, but its application in today’s beef industry is still met with some confusion. The purpose of this publication is to explain to county agents and producers how genomic testing works, how to use the results, and why this technology is valuable to cattlemen. This bulletin covers a simple history of genetic technology; parentage testing and simple inheritance; how genomic tests work, including sample collection and how results are used; and accuracy and GE-EPDs.

This publication provides information on (1) the nutrient content of manures available for land application, (2) how to determine manure application rates and whether supplemental fertilizer will be needed for maximum crop production and (3) how to use management techniques to maximize the fertilization potential of farm manures.

Plants develop seeds through a process called pollination. Pollination is the transfer of pollen from the stamen (male flower part) to the pistil (female flower part).

Sprouted grains are usually considered unsuitable for milling or distilling; however, they can serve as an excellent source of nutrients for cattle.
Wheat, which is commonly used for human consumption, is usually priced higher than other feedstuffs and is typically not utilized for livestock consumption. Sprouted wheat, however, is discounted heavily at the mill and may be economically feasible to incorporate into beef cattle rations.|

The pre-breeding period (2 months prior to breeding) is essential for preparing bulls for a successful breeding season. This is particularly important for yearling bulls as they are still growing and will use for energy during their first breeding season. Pre-breeding management should include an adaptation period, breeding soundness exam, health care, exercise, and an evaluation of body condition score. These topics are discussed in the circular. Proper pre-breeding management will increase reproductive efficiency and profitability in beef herds.

Due to cows’ universal exposure to manure, which contains E. coli and other gram-negative bacteria, as well as the requirement to maintain sec as low as possible, all cows should be vaccinated with one of the coliform vaccines available on the market. These vaccines have been proven to significantly reduce clinical coliform mastitis and have been shown to be profitable when incidence of clinical coliform mastitis exceeds 1% of milking cows.

In the Southeastern U.S., beef cattle producers focus on forage management and maximizing the grazing season. To that end, Southeastern cattle spend the vast majority of their lives either grazing or consuming stored forage. Cereal grains and coproduct feeds are also commonly used nutritional supplements for cattle in times of elevated nutrient requirement. Any disease or disorder in the beef herd represents a nutrient drain and subsequent economic inefficiency. Sudden shifts in dietary composition as well as mineral imbalances are the primary causes for most nutritional and metabolic disorders. This publication contains an overview of the common nutritional and metabolic disorders that may affect beef herds in the Southeast along with management strategies that can be used to minimize the effects of these disorders in beef cattle production systems.
