بررسی کاربرد سطوح مختلف کود خشک مرغ تخمگذار با ملاس و بدون ملاس در جیره بره های نر بلوچی

In a 2x4 factorial trial, 40 Baluchi lambs were used in a complete randomized design for study the effects of the use of different levels of dried poultry manure (DPM) and molasses on the feed intake, daily gain and carcass characteristics. Diets used in the experiment contained two levels molasses (0 and 10%) and four levels poultry manure (0,5,10 and 15%) which were made Isonitrogenous and Isocaloric. The lambs were fed individually ad libitum with a total mixed ration (TMR), water and block salt were freely avilable. Recording consist of individual lambs feed intake and weight gain for 6 periods of 14 days each. The result of this study indicated that lambs which consumed control diet (without DPM and molasses) had maximum average daily gain. But there was not significant difference between average daily gain of control diet and other treatments, except 15% DPM+10% molasses diet (P<0.05). Daily feed intake for lambs which consumed 5% DPM+0% molasses diet was more than other treatments. But only difference between that and 5% DPM+10% molasses diet was significant. There was not significant difference between feed conversion of control diet and other treatments, except 15% DPM+10% molasses diet (P<0.05). In respect to the analysis of variance of carcasses indicated that lambs which consumed control diet had maximum carcass weight. There was not significant difference between carcass weight of control diet and 10% DPM+0% or 10% molasses diets (P< 0.05).
