Desempenho de ovinos da raça dorper criados no sistema de semiconfinamento no Cariri Paraibano.

Abstract

The sheep industry in the current scenario is presented as a promising activity in the Northeast. The Dorper breed shows up as a great option for exploration, in view of its high rusticity and adaptability to arid regions, besides its good conformation of carcass, high growth rate and Average Daily Weight Gain (ADWG). Therefore, the aim of this study was to monitor the development of weaned sheep and evaluate the Average Daily Weight Gain (DWG) duo to the semi confinement and the type of parturition. Were used 12 Dorper sheep PO uncastrated aged between 2 and 4months. The animals were subjected to semi-intensive creation system, where they spent the day in the pasture and in the afternoon were confined in a stall where they were offered roughage and concentrated. The sheep were weighed every 8 days for 4 weeks and started the experiment with an average weight of 33.66 kg and finished with an average weight of 36 kg. In general, all animals showed a good Average Daily Weight Gain (DWAG), this happened as a result of semi confinement system that it was presented as a good technique to use in the region. The sheep that was born with simple birth performed better compared to lambs that were born by multiple birth, this can be understood by nutritional competition that exists between multiple births of animals. Also in the age effect was observed difference in DWAG and GPT animals.
