Abstract
The research was carried out in 2020 in the Blas area in the countryside of Aleppo with the aim of studying the productive efficiency of using Panicum maximum plant in feeding Awassi lambs compared to some traditional rations. 20 heads of Awassi lambs have been homogenized by weight (32.91 ± 1.34) kg and age (9 ± 2) months were used and distributed randomly into four groups: The first group T1: fed a concentrated feed mixture + 20% straw, the second group T2: fed on the concentrated feed mixture + 35% green barley, group III T3: fed on a concentrated feed mixture + 35% mixed barley and vetch green, group four T4: fed on a concentrated feed mixture + 35% green panicum. The results showed significant superiority (P <0.05) of T3 and T4 than that other groups in average daily and total weight gain,( 221 and 218 g / day / head, respectively) , compared to 194 and 196 g / day of T1 and T2, respectively. As well as 12.44 and 12.21 kg total weight gain, respectively. Compared to 194 and 196 g / day / head in addition to 10.88 and 10.98 kg total weight gain for the T1 and T2 groups, respectively. Non-significant differences were Observed in the dry matter consumption between groups. The best feed conversion rate was in the T3 group which reached 6.30 kg dry matter / kg live weight gain, and was significantly superior (P <0.05) of T2. T4 achieved the lowest cost of one kilogram weight gain 3002.6 SP and the highest profit index 7.23 compared with others groups, especially with the first group(control).
Keywords: Panicum, Mombasa F1, green fodder, production efficiency, Awassi sheep.
