| The study carried out in the college sheep field located in Sayada from Jan 28, 2022 till April 28, 2022 on 16 Awassi lambs distributed into four groups (four lambs per group), with approximately same body weights (20.22 ± 0.56 kg) and age (4 – 4.5 month) respectively. All lambs fed concentrated ration on 2 % base of the live weight with wheat straw as full and free diet during experiment period (90 days), the first group (control) fed normal diet free of dry bread yeast and black seed, the other three groups fed the same concentrate ration with the following supplement: 2 kg bread yeast / ton of feed for 2nd group, 1 kg black seed / ton of feed for 3rd group and 2 kg of bread yeast and kg of black bean / tons of feed for 4th group. At the end of experimental period blood sample obtained from lambs and two lambs from each treatment were slaughtered with average live weights weights 27.41, 25.25, 25.27 and 25.13 kg, The results showed that there was non significant effect of adding bread yeast and black seed in final weight, total and daily weight gain and feed conversion efficiency. Control group outperformed all experimental groups in the feed intake. The results showed that there was a non-significant difference in the PCV, hemoglobin, glucose, cholesterol and total protein levels of blood, while the third treatment was significantly (p≤0.0.5) superior in the percentage of glutathione (GSH) concentration on all treatments. It can be concluded that the addition of bread yeast and black seed did not have any significant effect on the performance of lambs and carcass traits. The study aimed to determine the effect of dry bread yeast and black seed additions on the productive performance of Awassi lambs (growth traits, feed intake, feed conversion efficiency and blood parameters). | ||
