Effects of Three Additives of Diet on Blood Antioxidant Ability in Tan Sheep
Twelve one-year old wethers and twelve ewes which were close in age and good health condition,growth and development were used in the experiment.It was investigated the effects on antioxidant ability in stabling Tan sheep fed the basal diets with concentrate to roughage ration of 3:7 by adding 2.0% yeast culture,0.3& Yea-Sacc and 3.0% alfalfa saponin by the feeding test.The results showed that at 20 d and 60 d,the experimental group Ⅰ had an extreme difference in MDA content in plasma than that of the control(P<0.01),there was no significant difference in MDA content in plasma between experimental group Ⅱ,experimental group Ⅲ and the control(P>0.05); at 40d,the differences among those groups were not significant in MDA content in plasma (P>0.05) ; the experimental group Ⅱ and Ⅲ were significantly higher in superoxide dismutase content in plasma than that of the control at 20 d and 40 d (P<0.01) ; at 20 d,40 d and 60 d,the total antioxidant capacity content in plasma of each groups were insignificant (P>0.05).The results showed that the three nutrients can improve antioxidant ability of Tan sheep to different degrees.
