G80-489 Feeding The Beef Cow Herd--Part I Factors Affecting The Cow Nutrition Program, Richard J. Rasby, Ivan G. Rush

University of Nebraska-Lincoln Extension: Historical Materials

Considerations for getting the most from your beef cow herd are covered in this NebGuide, including calving season, factors affecting nutrient requirements, cow rations and more.

Feed costs are the greatest expense in keeping a cow herd, and the nutrition program dictates reproductive performance. The ultimate goal for a cow/calf manager is to keep feed costs low, but still meet the nutrient requirements of the cow herd so reproductive performance is not impaired. Once these two factors are balanced, producers, through new genetics of added growth or milk production, can match increased weaning weight with the most economical feed resources …

G80-493 Developing Replacement Beef Heifers (Weaning-Breeding), Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the proper selection, nutrition, breeding, and management of replacement beef heifers from weaning to breeding. Proper selection and development of replacement heifers is one of the most important management programs in beef production. Replacement heifers should be selected and managed so they will conceive and calve early in the calving season, provide adequate milk production, and rebreed and calve every 365 days. Heifers bred as yearlings to calve as two-year-olds will produce an extra calf in their lifetime compared to heifers calving as three-year-olds, without detrimental effects on mature size, milk production, or calf weaning weights. The …

G80-537 Reproductive Trace Anatomy And Physiology Of The Cow, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Knowledge of basic reproduction will help a producer to obtain higher conception rates when using estrous synchronization and/or artificial insemination. The reproductive performance of a cow herd has a great influence on the income and profit realized. A good understanding of the anatomy and physiology of the cow's reproductive system is, therefore, beneficial for successful management. Knowledge of basic reproduction will help a producer to obtain higher conception rates when using estrous synchronization and/or artificial insemination. It will also allow for a better understanding of pregnancy examinations, reproductive diseases and calving difficulty problems.

G80-536 Reproductive Trace Anatomy And Physiology Of The Bull, Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

Understanding the anatomy and physiology of the bull's reproductive tract is beneficial for proper management. Good reproductive performance of a bull is necessary to obtain a high percent calf crop. A bull must be fertile and capable of servicing a large number of cows during a short breeding season for optimum production. Understanding the anatomy and physiology of the bull's reproductive tract is beneficial for proper management. A basic knowledge of the reproductive system will also help the producer to understand fertility examinations, reproductive problems and breeding impairments.

G80-495 Managing Two-Year-Old Beef Heifers (Calving - Rebreeding), Gene H. Deutscher

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the nutrition and management practices recommended for beef heifers during precalving, calving, and early lactation periods. Proper development of replacement heifers has a great influence on the success of calving and rebreeding them as two-year-olds. NebGuide G80-493, Developing Replacement Beef Heifers (Weaning-Breeding), points out that proper selection, adequate nutrition, and judgment in sire selection are all important management factors for developing heifers into high producing cows. With good management before breeding, a high percentage of heifers should be bred early in a short breeding season. Heifers should be pregnancy checked and the open ones culled. Thereafter, the …
