Abstract:
The present study was conducted to study the effects of replacing soybean meal with vermicomposting feed on growth performance and selective rumen and blood metabolites of fattening lambs. For this experiment, 16 male mixed breed lambs (Ghezel-Moghani) with an average initial weight of 20.5 ± 2.5 kg were used in a completely randomized design with 4 treatments and 4 replicates and 4 lambs in each replicate.The experimental diets, consisting of 0, 33, 67 and 100 percent vermicomposting feed replaced soybean meal. Lambs were fed freely with a diet containing 30% forage and 70% concentrate. Duration of the fattening period was 90 days. There was no significant difference (p<0.05) among the treatments in terms of final weight, average daily gain, dry matter intake and feed conversion ration. The data from the rumen metabolites indicated that diets had no effect on pH and fatty acids (p<0.05). But feed samples with 100% vermicomposting significantly increased rumen ammonia nitrogen and fatty acid acetate (p<0.05). Replacing soybean meal with vermicomposting feed did not have a significant effect on blood metabolites with the exception of blood urea nitrogen which showed a slight linear increase numerically. The results of this study shows that vermicomposting feed containing high nutrients can be a suitable replacement for soybean meal.
