Abstract

Milk yield from 158 Brangus cows bred to 6 sire breeds (Bonsmara, Brangus, Charolais, Gelbvieh, Hereford, Romosinuano) was measured for 3 yr to estimate relationships of milk yield of cows and postweaning ADG of their calves on 2 postweaning systems (dry lot or wheat pasture). Milk yield was...

Abstract

This study aimed to estimate the genetic parameters and genetic and phenotypic trends for weight at weaning (PD), yearling weight (PS), average daily gain from birth to weaning (OMDND), average daily gain from weaning to yearling (OMDDS), days to reach 160 kg at the preweaning phase (DI60) and days ...

Abstract

The present research is the second phase (2 yr) of a multiyear cow-calf project examining the effect of stocking method, i.e., continuous and rotational, and fixed stocking rate on beef-cattle production. Two sets of 4 adjacent pastures, each containing a mixed warm-season, perennial grass sod...

Abstract

Disposition or temperament of cattle is a measure of the animal's relative docility, wildness, and handling ability during processing in the pen as well as in the handling facilities. Easily excitable animals compromise both their own safety and the safety of handlers. The Iowa Tri-County Steer...

Abstract

Leptin is a hormone that affects the regulation of feed intake, energy balance and body composition in mammals. Several polymorphisms in the bovine leptin gene have been associated with phenotypic variance of these traits. We evaluated two known single nucleotide polymorphisms (SNPs) in the leptin...
