The objective of this study was to evaluate the influence of body condition at birth on Alpine goat productive parameters in early lactation. Sixty-eight females were assigned to three groups according to the body condition score (BCS) – low (1.00 – 2.75); intermediate (2.75 – 3.50) and high (3.50 – 5.00) and evaluated from kidding to the eighth week of lactation. The feed intake and milk production were recorded on a daily basis and the body weight, body condition score […]
Keywords: intake; milk production; postpartum

Fifteen crossbred cows (Holstein-Zebu) from EPAMIG-Leopoldina Experimental Farm with an average weight of 511.8 kg were allocated into an experiment in a complete randommized design, in four treatments, with four animals in the treatments 1, 2, and 4 and three in the treatment 3. The treatments were cosntituted of diets with corn silage and concentrate (60:40) and were fed individually and ad libitum and their contents in percentage of urea were: T1=0.0; T2= 0.7; T3= 1.4 and T4=2.1 corresponding to […]

The aim of this experiment was to compare the efficiency of a hormonal protocol, associated to the temporary weaning for 96 hours, with the definitive weaning at 60 days in beef cows, for the induction of estrus and ovulation. One hundred and eighty-three suckled beef cows were used. The breeds of the cows were Charolais (C) and Nellore (N) and their crosses. The animals were genotyped as homozygous (HOM) and heterozigous (HET) for the microsatellite BMS3004, that is localized in […]
