Impacts of stocking density on development and puberty attainment of replacement beef heifers
(2017-12-01)
In all, 60 Angus×Hereford heifers were ranked by age and BW (210±2 days and 220±2 kg) on day 0, and assigned to: (a) one of three drylot pens (10×14 m pens; 10 heifers/pen) resulting in a stocking density of 14 m2/heifer ...
Impacts of postweaning growth rate of replacement beef heifers on their reproductive development and productivity as primiparous cows
(2019-10-03)
This experiment evaluated the effects of postweaning body weight (BW) gain of replacement beef heifers on their reproductive development and productivity as primiparous cows. Seventy-Two Angus × Hereford heifers were ranked ...
Effect of forage species and supplement type on rumen kinetics and serum metabolites in growing beef heifers grazing winter forage
(2017-12-01)
The objective of this study was to determine the effect of stockpiled forage type and protein supplementation on VFA production, serum metabolites, and BW in yearling beef heifers. Over 2 yr, spring-born, Angus crossbred ...
Management of age at puberty in beef heifers to optimize efficiency of beef production
(2013)
Age at puberty in beef heifers can influence economic efficiency of beef production through effects on both age at first calving (2 vs. 3+ years of age) and the time of conception of heifers in their initial breeding season. ...

Impact of 24-h feed or water, or both, deprivation on feed intake, metabolic, and inflammatory response in beef heifers
(Oxford Univ Press Inc, 2018-09-01)
This experiment evaluated the effects of 24-h feed or water, or both, restriction on hay intake, metabolic, and inflammatory response in growing beef heifers. Forty Angus x Hereford heifers were ranked by initial body ...
