The effect of monensin and supplemental fat on growth performance and blood metabolites in Mazandaran zel lambs
This experiment was conducted to assess the effect of fat and Monensin in diet on daily dry matter intake¡ total feed intake¡ final weight¡ total weight gain¡ daily weight gain¡ feed conversion ratio¡ blood metabolites (glucose¡ urea¡ calcium¡ phosphorous¡ triglycerides¡ cholesterol and total protein) in Mazandaran Zel lambs breed. A factorial design of 2×3 was used in this experiment (two levels of fat¡ 0 & 4 percent and three levels of Monensin¡ 0¡ 20 & 40 mg per kg respectively). twenty four male lamb from Mazandaran Zel breed with average weight of 21.9±0.64 kg and 3-4 months ages were used. The experiment was conducted with an adaptation period of eleven days and the experimental period lasted for 63 days. Lambs live body weight was determined in a 21 days interval. blood samples were drived from each experimental lambs at the end of experiment were analysed to determine the mentioned metabolites. The results of this experiment indicated that the effect of different levels of fat & monensin on daily dry matter intake¡ total feed intake¡ final weight¡ total weight gain¡ daily weight gain¡ feed conversion ratio & blood glucose was not significant¡ but a significant effect was observed (p
