Abstract
This study was conducted to determine the effect of adding of dried Molasses Distillers Condensed Soluble with bran (MDCS+B) to diets on growth performance, fermentation parameters, protozoa population and some blood biochemical parameters of fattening lambs. Twenty-one Mehraban male lambs (Weight average 35 ± 0.5) and 4 month age old were used in 3 treatments for 74 (14 days adaptation and 60 days experiment) days in randomized completely design. Lambs were offered either MDCS+B (control, CON) or the concentrate supplemented with 25 % MDCS+B; or 50% MDCS+B. Lambs were weighed at weekly intervals and blood samples were collected on days 30 and 60 .The rumen fluid samples were collected on days 60 during the fattening period. The results showed that dry matter intake were not different between dietary treatments at second month and total period of experiment as compared to the control group. The addition of MDCS + B at level of 25% increased ruminal ammonia concentration by 10.35% (P=0.054) and total rumen volatile fatty acids concentration increased by 46 % as compared to the control group (P= 0.016). The total protozoa population were not influence by MDCS+B. The price of each kilogram of ration for 25 and 50% MDCS + B were 74 and 155 Tomans respectively, when compared with the control group. The overall results of this study showed that the use of MDCS + B reducing feed costs and can be used up to 50% of concentrate.
