G87-851 Improving Reproductive Performance And Productivity Of Beef Herds, Gene H. Deutscher Jan 1987

G87-851 Improving Reproductive Performance And Productivity Of Beef Herds, Gene H. Deutscher

Historical Materials from University of Nebraska-Lincoln Extension

NebGuide discusses management practices that can be used to improve reproduction and productivity of beef herds. The major objective of cow-calf producers should be to wean a calf from each cow every year. The average calf crop weaned in Nebraska is estimated at 80 calves weaned per 100 cows in breeding herds. A realistic goal is 90 to 95 calves weaned per 100 cows.


G87-895 Pelvic Measurements For Reducing Calving Difficulty, Gene H. Deutscher Jan 1987

G87-895 Pelvic Measurements For Reducing Calving Difficulty, Gene H. Deutscher

Historical Materials from University of Nebraska-Lincoln Extension

Pelvic measurements in heifers and bulls can be an important tool to help reduce the incidence and severity of calving difficulty. Calving difficulty results in a major economic loss to beef producers. This loss is estimated at $750 million annually nationwide. Calving difficulty increases calf death loss, cow mortality, labor and veterinary costs; it delays the return of cows to estrus and reduces conception rates. It also lowers calf weaning weight and market value, which results from breeding young heifers and cows to easy calving bulls to reduce calving difficulty. Studies show calf losses of 4 percent within 24 hours ...
