Effect of postweaning implantation of zeranol and dietary energy level on growth and reproductive performance of replacement beef heifersDownload
Eighty-one heifer calves weaned at an average age of 6 mo were used to study the effect of postweaning zeranol implantation, on the growth and reproductive performance of heifers fed to grow slowly on three dietary energy levels. Forty heifers were implanted with 36 mg of zeranol at 30 d and...
Fiber-type proportions and diameters in the longissimus muscle of beef heifers undergoing catch-up (compensatory) growthDownload
Fifty-three Hereford crossbred heifers (211 ± 28(mean ± SD) kg, 197 ± 13 d of age at day 1) were used to study the effects of mild, chronic feed restriction followed by refeeding on some longissimus muscle fiber characteristics. Five animals were slaughtered on day 1 for analysis of initial...
Growth performance and carcass composition in beef heifers undergoing catch-up (compensatory) growthDownload
Fifty-three Hereford crossbred heifers (211 ± 28 (mean ± SD) kg; 197 ± 13 d of age at day 1) were used to study catch-up growth and its effects on carcass composition. Five heifers were slaughtered on day 1; the remaining 48 were randomly penned in groups of six and assigned to treatments as...
