Effect of linseed and sesame seeds on productive traits and total cholesterol level of Awassi lambs

Abstract

A field trail was carried out in the Ruminant Research Station Pertaining The Office of Agricultural Researches/ Ministry of Agriculture. The aim of this study was to investigate the effect of linseeds and sesame seeds on total cholesterol level of Awassi lambs. The design of lab experiments was CRD. The experiment Involved of fifteen Awassi lambs ages 7-9 months and average 34.25 kg live body weight were used Lambs were divided randomly into three equal groups, Group one A = Standard concentrate ratio, group two B = adding 5% linseeds to standard concentrate ratio, while group three C = adding 5% sesame seeds to standard concentrate ration. Results of the field trial was revealed that group B in average daily gain, improved in food conversion ratio, hot and chilled carcass weight, decreased in total cholesterol of tail fat and subcutenous fat and Rib- eye muscle area was increased (201 gm/animal/day, 8.16 kg dry matter/ kg gain, 27.56 kg, 27.166 kg, 98.45, 70 mg/ 100 ml and 15.66 cm2 respectively compared with other groups. while group C was revealed in decreased total cholesterol of inter muscular fat and increased ratio of lean to fat 42 mg/ 100 and 3.28 respectively compared with other groups. From this study we can concluded that using linseeds and sesame seeds to diet of ruminant led to increase average daily gain and improved the efficiency of meat production and sharp decreased in total cholesterol of carcass fat. It can be consumption this meat and positive effective for health human.
