Efeito do manejo da amamentação no desenvolvimento ponderal de cordeiros pantaneiros

Abstract

The present study aimed to evaluate the weight performance of Pantanal lambs from birth to weaning. A total of 63 lambs from a breeding season were used using estrus synchronization protocol. At two weeks of age, the animals were randomly assigned to three different feeding maneuvers, which were characterized according to the length of stay with the mother in different breastfeeding management systems: MAM1 lambs that were fed 30 min in the morning and 30 min at afternoon; MAM2- Lambs that stayed with their mothers for 24 hours; MAM3- Lambs that stayed with their mothers from 16 to 8 in the morning. To evaluate weight gain, lambs were weighed every 7 days on a mechanical scale. Table 1 shows the weight values of lambs from birth to weaning, and presents a statistical difference for treatment 3, where weaning weight is higher than the other treatments. Therefore, the alternative management of controlled feeding can be used continuously when it comes to weight gain and development of lambs, therefore weaning heavier lambs with good perspective of performance in the rearing.
