Body condition and productive performance of Alpine goat in early lactation

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 and milk composition at weekly intervals. Animals with a high body condition score presented lower dry matter intake, neutral detergent fiber and crude protein compared to those with low and intermediate body condition scores. The average time for dry matter intake recovery of the animals with the three body condition scores was 16 days (2.3 weeks) postpartum, and stabilization by the end of the experiment. In the sixth week of lactation, animals with low body condition score had the same body weight of animals with intermediate body condition score. There was no effect of the body condition at birth on the body condition score changes and milk production during the experiment. The milk fat content of animals with high body condition score was lower in the first two weeks postpartum compared to animals with low and intermediate body condition score. The high body condition at birth influences negatively the ad libtum intake of dairy goats in the early lactation, but when it is used feed of high quality with high energy levels, the influence of the body condition at birth is nil to variations in weight, BCS and milk production.
