In order to conduct a study on the Fed and the main properties of lamb carcasses from Karnobat local breed, depending on the type of animal in the herd of the Institute of Agriculture - Karnobat study was 20 lambs. For the purpose of the experiment after weaning of lambs - 2 months two groups were formed, each of 10 animals - 5 with clozed fleece and 5 with open fleece. Testing animals had an average type of birth loners sex male, age and live weight. First group was used as a control, the second experimental. When they reach slaughter weight approximately 30 kg, after 24-hour starvation diet animals were slaughtered and carcass analysis took place. It was found that the experimental group fed with formula with lower protein content showed a 15 g less growth and a 617 g higher feed consumption per 1 kg gain compared with the control group. Larger amounts of protein in the mixture resulted in obtaining logs with more fat. It is recommended that meat producers to use the lessons learned as a guide for the formation of lamb logs at a certain level of eating quality characteristics consistent with market requirements.
