The effect of replacement sainfoin forage with alfalfa in dietary concentrate level on performance and carcass quality of fattening Lori lambs

This research was conducted to investigate the effect of replacement sainfoin forage with alfalfa in dietary concentrate level on growth performance and quantitative and qualitative carcass traits of Lori male lambs. Accordingly, 54 male of Lori lamb with a mean live weight of 30 kg were selected. Treatments included two levels of forage (alfalfa and sainfoin) and three levels of concentrate (60, 70 and 80%). The experiment was conducted as factorial with completely randomized design (3×2) with three replications (replication each consist of three lamb). The results showed the most daily gain and the best feed conversion ratio, carcass yield, the percentage of lean meat were related to lambs fed with sainfoin and 70% concentrate. The production cost per kilogram of carcass and lean meat of lambs fed sainfoin and 70% concentrate were lower than other treatments. The qualitative properties such as pH, chemical composition and meat color were not affected by exrimental diets. In general, the results this research showed that using from sainfoin forage and 70% concentrate can be effect on performance and carcass characteristics of Lori male lambs.
