Abstract: The present study was carried in the central laboratory for food and feed (CLFE), Agriculture Research Center and EL-Gemeza Experimental Station, Animal production Research Institute, Egypt. Eighteen Rahmany lambs after weaning (l4weeks) and about 20kg live body weight were used to evaluate the nutritional value of Barley silage (BS) through 3 digestibility trials and effect of feeding (BS) on productive performance during the growing period of lambs. Lambs were assigned to three similar groups ( 6 in each) to evaluate the following ration:
1st rationn:100% of NRC allowances from concentrate feed mixture(CFM) (1985) +Rice straw (RS) ad lib
2nd ration: 75% of NRC allowances from (CFM) of NRC (l985)+Plant Barley silage (BS) ad lib
3rd ration: 50% of NRC allowances from (CFM) of NRC (1985)+Plant Barley silage (BS) ad lib
The results revealed that, the total dry matter intake (DMI) for ration T2 and T3 were gradually increased with advancing age (18 to 36 weeks). The live body weight gain (LBW) of lambs fed ration 2 through the period from 26 to 36 weeks of age were significantly (P<0.05) higher than those of T1 and T3. The feed conversion (feed/gain) 12 ration was the best (P<0.05) values. The CP, CF, EE, and NFE digestibility for rams fed ration T2 were higher (p<0.05) than those fed T1 and T3. Also the nutritive value, as TDN and DCP take the same trend. The inclusion of barley silage in the ration for lambs improved economical efficiency and decreased cost of Kg gain. It could be concluded that, Inclusion of barley silage in the ration improved dry matter intake, digestibi1ity of most nutrients and nutritive value; live body weight and economic efficiency specially ration T2 (75% of CFM of NRC 1985 + barley silage ad lib).
Keywords: barley silage, digestibility lamb performance, economical efficiency.
