G85-761 Feed Additives For Beef Cattle, Rick Stock, Terry L. Mader

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses feed additives, including how they work, feeding restrictions and feeding recommendations.

One of the best methods to reduce feed costs is through the use of feed additives. Their primary effects are to improve feed efficiency and/or daily gain. Some feed additives have secondary benefits which include reducing the incidence of acidosis, coccidiosis, and grain bloat, while others suppress estrus, reduce liver abscesses, or control foot rot problems.

Feed additives can be divided into five general categories: 1) ionophores; 2) antibiotics; 3) estrus suppressants; 4) buffers; and 5) others. Each feed additive has its own characteristics and feeding …

G85-759 Prominent Congenital Defects In Nebraska Beef Cattle, J. L. Johnson, H. W. Leipold, Donald B. Hudson

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes congenital defects that affect the economic value of beef cattle, and provides recommendations on how to minimize them in breeding programs.

Congenital defects are abnormalities of structure or function present at birth. They may be caused by genetic or environmental factors, or a combination of both. The causes of many defects remain unknown.

Developmental defects may be lethal, semi-lethal, or compatible with life, causing very little effect or only aesthetic effect.

With the increasing use of artificial insemination (AI) in cattle, defects are no longer rare occurrences and are important collectively to the cattle industry. Congenital defects …

G85-741 Estrous Synchronization For Beef Cattle, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the potential benefits of estrous synchronization, how the products and programs work, and the results and costs involved. Estrous (heat) synchronization can help beef producers improve production efficiency and economic returns. Controlling estrus and ovulation in cycling females means breeding is completed in a short period of time. Instead of females being bred over a 21-day period, synchronization can shorten the breeding period to less than 5 days, depending on the program selected. The use of synchronization has great potential for improving beef production, but it requires good management for success. Producers should understand the advantages, as …
