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.

In order to investigate the effect of feeding zinc-methionine (Zn-Met) supplementation on growth performance, nutrients digestibility, ruminal fermentation parameters and some blood metabolites, an experiment was conducted on fifteen Kermani male lambs with average initial body weight of 32.1 ± 0.88 kg as a completely randomized design with 3 treatments and 5 replicates for 8 weeks. The experimental treatments were basal diet without supplemental Zn (Control), basal diet plus 50 mg Zn/kg diet of Zn-Met, and basal diet supplemented with 100 mg Zn/kg diet of Zn-Met. The results showed that lambs fed with 100 mg/kg diet of Zn supplementation had lower feed intake than the other treatments (P<0.01). Lambs received 50 mg Zn /kg of diet had higher average daily gain than those on control diet (P<0.05). Lambs fed with Zn supplementation (50 or 100 mg/kg) had better feed conversion ratio than the control group (P<0.05). The apparent digestibility of dry matter, organic matter and neutral detergent fiber (NDF) was higher in lambs fed 50 mg/kg of Zn supplementation than those of the control (P<0.05). However, no difference in fat and acid detergent fiber (ADF) digestibility was observed between treatments. Additionally, feeding Zn-Met supplementation diet had no significant effect on pH and ammonia nitrogen of ruminal fluidas well as serum glucose, total protein, triglyceride and urea concentrations of lambs. According to these results, feeding 50 mg/kg diet of Zn supplemented increases feed nutrients digestibility and compared with 100 mg of the supplement, has better effects on growth performance of fattening lambs.

This study was conducted to determine the effects of addition of the pomegranate seed oil (PSO) in the diet on growth performance, diet digestibility and rumen fermentation parameters of fattening lambs. Twenty one Sanjabi lambs, with average body weight of 27.5±2.6 kg and 3 months of age, were used in a completely randomized design with 3 treatments and 7 replicates.The experimental treatments included diet free of PSO (control diet), and diets containing 2 and 4% of PSO. Daily feed intake, diet digestibility and rumen fermentation parameters were measured by standard methods. The lambs were weighed at the beginning and the end of the finishing period for estimation of average daily gain (ADG). The DMI in the lambs fed on the diets containing PSO was higher than that of control (P<0.05). There was no differences along treatments concerning ADG, although, in lambs receiving PSO thetrend was to be increased. Dry matter and organic matter digestibility in the lambs fed on 4% PSO were higher than those of the other groups (P<0.05). Concentrations of volatile fatty acids (VFAs) were not affected except valeric acid, however, incorporation of 4% PSO to the diet increased molar percentage of propionic acid and decreased acetate to propionate ratio, significantly. Ammonia nitrogen concentration was not affected by adding PSO to diet. The results of this experiment suggest that pomegranate seed oil has potential to improve the digestibility and ruminal fermentation efficiency of the diet of fattening lambs.
