Cullin the Beef Cow Herd
Removing select cattle from a herd (culling) is done to improve herd performance and profitability Production and market conditions influence culling criteria Some cattle are obvious candidates for culling (e g , cows with poor breeding performance or cancer eye), but cattle can and should be culled for reasons that may not be readily observable Simply put, cows are selected for culling based o...
متن کاملHerd factors associated with dairy cow mortality.
Summary studies of dairy cow removal indicate increasing levels of mortality over the past several decades. This poses a serious problem for the US dairy industry. The objective of this project was to evaluate associations between facilities, herd management practices, disease occurrence and death rates on US dairy operations through an analysis of the National Animal Health Monitoring System's...
متن کاملUtilization of Heterosis in a Beef Cow Herd
George H. Shull, while working as a corn geneticist at the Cold Spring Harbor Laboratory from 1904 to 1915, observed that when two different pure-bred lines of corn were crossbred the resulting progeny exhibited physical traits superior to those of the parents (Glass, 2010). Shull described the offspring of pure-bred crosses as having increased heartiness, size, fruitfulness, speed of developme...
متن کاملProduction responses following strategic parasite control in a beef cow/calf herd.
Strategic parasite control has been reported to improve performance in a beef cow/calf herd that does not demonstrate clinical parasitism. This study was conducted to determine if strategic anthelmintic treatment at turnout and at midsummer would improve growth and reproduction. Two cow/calf groups of similar composition were grazed on separate, but equivalent pastures in the spring, and at mid...
متن کاملEvaluation of life-cycle herd efficiency in cow-calf systems of beef production.
A deterministic beef efficiency model (BEM) was used to evaluate life-cycle herd efficiency (LCHE) in cow-calf beef production systems using four breed groups of beef cattle. The breed groups were Beef Synthetic #1 (SY1), Beef Synthetic #2 (SY2), Dairy Synthetic (DS), and purebred Hereford (HE). The LCHE was defined over the lifetime of the herd as the ratio of total output (lean meat equivalen...
