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) …

This experiment evaluated the effects of postweaning body weight (BW) gain of replacement
beef heifers on their reproductive development and productivity as primiparous cows …

Our objective was to determine whether beef heifers could be developed by delaying the
majority of weight gain until the last third of the developmental period before the onset of the …

Age and weight at puberty in beef heifers were hypothesized to be jointly dependent random
variables with the joint distribution conditional upon values of exogenous variables such as …

Studies in numerous species provide evidence that diet during development can mediate
physiological changes necessary for puberty. In cattle, several studies have reported inverse …

Brahman× British crossbred heifers (n= 40 and 38 heifers in yr 1 and 2, respectively) were
used to evaluate the effects of calf weaning age and subsequent management system on …

It was hypothesized that metabolic programming of processes underlying puberty can be
shifted temporally through the use of a stair-step compensatory growth model such that …

ABSTRACT Twenty Simmental× Angus, half-sibling, postpubertal heifers (initial BW of
443±9 kg) were allotted randomly into 2 treatment groups to evaluate if initial BCS affects …

One hundred 7-mo-old spring-born beef heifers (215 kg) were used to evaluate effects of
level of supplementation and short-term concentrate feeding on age and weight at puberty …

Precocious puberty (< 300 d of age) can be successfully induced in a majority of heifers with
early weaning and continuous feeding of a high-concentrate diet. The objective of this …
