اثرات جایگزینی سطوح متفاوت سویای پرچربی با کنجاله سویا بر عملکرد پرواری، فراسنجه های خونی و تجزیه پذیری ماده خشک در بره های پرواری نژاد زل

AAn experiment was conducted to evaluate the effect of replacing different levels of Full Fat Soybean with soybean meal on performance, degradation parameters and blood metabolites on 20 fattening Zel lamb. Fattening diet was made with different percentage of soybean meal that replaced with full fat soybean. The concentrate contained 8 percent of soybean meal replaced with 0, 33, 66 and 100 percent full fat soybean and then 70 percent to 30 percent was mixed with corn silage. The dry matter degradation parameters of 4 indicated diets were determined by in situ method using 4 fistulated sheep. Diets were incubated at 0, 4, 8, 16, 24, 48 and 72 hours. Daily body gain and the amount of consumed diet showed significant different at the biginig of the experimental treatments, but FCR did not showed significant different. Blood parameters, were not experiment. At the end of study, triglyceride and glucose levels had not significant different; but the amount of cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) was significant different. However cholesterol and LDL as well as the amount of HDL was elevated. In in situ experiment, significant differences were observed in a, b fraction and effective dry mater 0/02. The result of dry matter degiodation, blood parameter and body weight gain showed the use of full fat soybean in the diet increase the performance of fattening lambs.
