Beef heifer weight loss during gestation and its effects on progeny performance
نویسندگان
چکیده
The objective of the present study was to evaluate intensity weight loss in beef heifers during gestation and its effects on progeny performance up 205 days age. Sixty pregnant aged 3 or 4 years, born between 2015 2017, from rotational cross Charolais Nellore breeds were used. Females divided according period (7, 14, 21%) age at first calving (3 years), a completely randomized design x 2 factorial scheme. Lost 21% (T21) body had higher conditions end breeding season (3.12 vs 3.02 3.04 points) lower (341.96 386.26 362.95 kg) about T7 T14 heifers. birth calves showed tendency increase as increased, with values 29.46, 30.60 32.76 kg for treatments T7, T21, without reflections post-weaning progeny. In general, 14 heifer's pregnancy reduces calving, while calved years are heavier give rise greater productive potential

Winter grazing system and supplementation of beef cows during late gestation influence heifer progeny.
A 2 × 2 factorial arrangement of treatments was used to evaluate effects of dam winter grazing system and supplementation in the last third of gestation on subsequent BW gain, feed efficiency, and reproduction in heifer progeny. Crossbred cows (yr 1, n = 109; yr 2, n = 114; yr 3, n = 116) grazed range (WR) or corn residue (CR) during winter and within grazing treatment received 0.40 kg/d of 31%...

This experiment was conducted to determine the effects of interval feeding of whole sunflower seeds on the performance of beef cows and their progeny. During mid to late gestation, 144 multiparous, spring-calving beef cows (588 kg of initial BW; 5.6 initial BCS; 4 to 13 yr old) were individually fed 1 of 3 supplements 4 d/wk for a 76-d period. Supplements (DM basis) included: 1) 0.68 kg of soyb...

The effect of oxfendazole (Synanthic) on weight gain and reproductive performance of spring-born heifer calves was evaluated at five locations (IL, IN, MI, MO, ND). Three hundred thirty-eight mixed-breed beef heifers (293.4 kg) blocked by weight and age were randomly allotted to one of two treatments. Treatment 1 heifers were dewormed via intraruminal injection of oxfendazole. Treatment 2 heife...
