胡麻饼代替豆粕对绵羊脏器指数和肝脏抗氧化酶活性能的影响
首发时间:2018-09-17
摘要:本试验旨在研究胡麻饼代替豆粕后对绵羊脏器指数和肝脏抗氧化性能的影响。本试验随机选取24只5月龄、体重(26.0±1.0)kg的杜泊×小尾寒羊杂交F1代公羔,按照胡麻饼代替豆粕的比例(0,6%,12%和18%)随机分为4组:1)胡麻饼替代比例0%(CK组);2)胡麻饼替代比例6%(Ⅰ组);3)胡麻饼替代比例12%(Ⅱ组);4)胡麻饼替代比例18%(Ⅲ组)。试验期共70 d,预饲期为10 d。结果表明:1)胡麻饼代替豆粕显著降低了试验Ⅲ组宰前活重、肝脏和肺脏的器官指数(P<0.05),但对肝脏、肾脏和各个胃室的器官指数没有显著影响(P>0.05)。2)胡麻饼代替豆粕不影响肉羊中SOD活性、T-AOC和MDA含量(P>0.05);同试验Ⅲ组和CK组相比,试验Ⅰ、Ⅱ组肝脏中CAT的活性显著升高(P<0.05);试验Ⅱ组中肝脏GSH-Px的活性最高。综上:胡麻饼代替豆粕可以影响肉羊脏器指数,提高绵羊抗氧化能力。因此,本试验条件下,胡麻饼代替豆粕不宜超过2/3。

Effect of Replacement of Soybean Meal by Oil Cake of Flax Seed on organ index and antioxidant enzyme activity of liver in lambs
Abstract:The objective of this experiment was to investigate the effects of substitution of soybean meal by flax seed cake on organ index amd antioxidant enzyme activity of liver in lambs. A total of 24 1/2 Dorper (♂)× 1/2 Small Tail Han sheep (♀) ram lambs (150 d of age; 26±1 kg of body weight) were selected randomly and equally assigned into 4 groups according to the proportion of the oil cake of flax seed substituting soybean meal (0, 6%, 12% and 18%): 1) 0% of the oil cake of flax seed(CK ); 2) 6% of the oil cake of flax seed(Ⅰ); 3) 12% of the oil cake of flax seed(Ⅱ); 4) 18% of the oil cake of flax seed(Ⅲ). The experiment was conducted over 70 days, with the first 10 day for adaptation. The results showed that: 1)The organ index of liver and lung og group Ⅲ were significantly lower than those in other three groups(P<0.05). There were no significantly difference in organ index of heart, kidney, rumen, reticulum, omasum and abomasum between treatment group and group CK(P>0.05). 2) There was no significant difference in the activity of SOD, the T-AOC and the content between treatment and control group(P>0.05). The activity of CAT in the liner of the group Ⅰand Ⅱ was significantly higher than that in the group Ⅲ and CK(P<0.05). The activity of GSH-Px in the liver of group Ⅱ was significantly higher than that of other there group(P<0.05). In conclusion, replacing soybean meal with the oil cake of flax seed in a certain proportion could effectively effect organ index amd antioxidant enzyme activity of liver. Moreover, the oil cake of flax seed could not 12% in diets under the condition of this experiment.
