Comparison Of Sire Expected Progeny Differences To Actual Performance Of Crossbred Offspring, B.A. Freking, D.M. Marshall
Comparison Of Sire Expected Progeny Differences To Actual Performance Of Crossbred Offspring, B.A. Freking, D.M. Marshall
South Dakota Beef Report, 1988
Actual performance of crossbred calves produced at the Antelope Range Livestock Station was evaluated and compared to the sire's expected progeny differences (EPDs) as reported in 1988 beef breed association sire summaries. Comparisons were made between high EPD and low EPD sire groups in retrospect for actual birth weight and weaning weight performance of crossbred progeny. Separate analyses were completed for Polled Hereford, Simmental, Tarentaise and Angus sires. Progeny of high EPD sires ranked higher for average birth weight than progeny of low EPD sires for all sire breeds. Rankings for calf weaning weight were less consistent than for birth …
Relationship Of Sire Expected Progeny Differences To Maternal Performance Of First-Calf Daughters In A Commercial Herd, D.M. Marshall, B.A. Freking
Relationship Of Sire Expected Progeny Differences To Maternal Performance Of First-Calf Daughters In A Commercial Herd, D.M. Marshall, B.A. Freking
South Dakota Beef Report, 1988
Maternal performance for first calf production was evaluated in retrospect for daughters whose sires had expected progeny differences (EPDs) available from 1988 beef breed association national genetic evaluation summaries. When grouped into high EPD and low EPD groups, sire EPD group averages for actual daughter milk production and weaning weights of daughters' off spring consistently ranked the same as sire group average EPDs for milk and maternal weaning weight, although differences between groups were not statistically significant.

When cattle are put in feedlots, they change diets and environments. This NebGuide discusses ways to minimize possible losses caused by those changes. Cattle are a vital link in the human food chain in the United States. The utilized agricultural area in this country is about 1.06 million acres, of which 64 percent is range (government and private). Grazing is the only practical method of harvesting these valuable resources. Ruminants convert forage produced by the soil nutrients, water and solar energy to a high quality protein source for humans. The feedlot phase of cattle feeding follows the utilization of roughages …
