The beef goat activity has been developed and expanded in the last years, attracting lots of business men to invest in the activity potentials. The aim of this study was to evaluate the body weight gain in lambs of Santa Inês breed,in the periparturition, proceeding from Brazilian Central tableland.

In the livestock 03 was evaluated the influence of two year season (dry and water station) upon the male and female of simple birth. The statistical analyses were carried out by the SAS statistical program and the means were compared by the t test (p<0.05).The results from livestock 01 showed superiority in the performance of animals kept in the feedlot system in the postpartum.  In the livestock 02 was superiority considering the water station and for lambs from simple parturition. In the livestock 03 occurred similar performancefor the water and dry station, with superiority for the males. The handling of sheep feedlot handling before the partition and total feedlot of lambs with supplementation. The total lams feedlot with supplementation promoted good results in both evaluated season
