Effect of using three varieties of sorghum Bicolor stover silages on performance of growing and fattening lambs [electronic resource].

study aimed to evaluate and compare three varieties of sorghum bicolor stover after ensiled without any additives. Twenty Ossimi Lambs were selected and randomly distributed in a completely randomized block design with four dietary treatments: control ration (CR) which comprised of60% concentrate feed mixture (CFM) and 40 % clover hay,and the three tested silage rations R1, R2, R) were formulated from 50% CFM for each in addition 50% of the respective 800·2 hybrid, ICSV-273 and Dorado varieties silages. with five replicates and experimental period of 120 days for growth-fattening performance trial. Four digestibility trials were performed to evaluate the feeding value of the control and silage rations. Results indicated that no significant differences were noticed among the three types of silage respecting pH, ammonia -N and butyric acid. The total VFAs, lactic acid and acetic acid concentrations were significant (P<O.05) lower with ICSV·273 than those of other types. Totally, on the basis of pH, acid concentrations and ammonia~N, all silages were of good quality. Digestibility coefficients of DM, OM, CF and NFE were significantly (P<O.05) higher with all silage rations than the control one, while vice versa was occurred with digestibility of CP and EE.
