This research aimed at evaluating ponderal performance of the calves from birth to 189 days of age. Ninety-five calves were used (55 Aberdeen Angus and 40 Hereford), grazing natural pasture. Milk production of cows was estimated by the weight-suckled-weight method, and ponderal performance of the calves was evaluated in 21-day intervals from birth. Calving season was divided at time 1 (September) and time 2 (October). For analyses, it was included in the statistical model as fixed effects, breed of the […]
