ABSTRACT
The effect of energy intake during late gestation in beef cows on the placentas, behaviour and morphometry of the female calves at parturition and age at puberty was evaluated. Thirty-one British multiparous cows, inseminated by FTAI (fixed time artificial inseminated) and carrying female calves were assigned to two energy-feeding treatments on Day –90 (Day 0=parturition): i- 125% of requirements (AL, n=15) and ii- 75 % of requirements (BA; n=16). Duration of delivery and characteristics of the placenta were recorded in the cows. In the calves, time trying to stand, suckle and the total time suckling were recorded. Postpartum live weight, length and height of the calves were recorded. Duration of delivery and the characteristics of placentas were not affected by the treatments; neither the calves birth weight. Height of the calves was lower in BA compared to AL (70.2±1.0 vs. 72.2±1.0 cm, P=0.03); that difference disappear when using birth weight as a covariate.
The rest of the morphometry, as well as the behaviour, were not affected by the treatments, although calves of BA tended to suckle earlier than AL (9.2±8.9 and 24.6±8.4 min; P=0.08). Daily weight gain was higher in calves AL (P<0.01) and age at puberty was not affected by treatments. The energy restriction imposed during the last third of gestation did not generate evident changes in the evaluated variables, possibly due to the adaptability that meat cows have in pastoral systems. |
