Effects of Nutritional Compound Additives on Growth Performance, Antioxidant Capacity, Liver Function and Toxin Residues of Growing?Finishing Pigs Fed Diets Contaminated with Aflatoxin B1
摘要
Abstract
This experiment was conducted to investigate the effects of nutritional compound additives on growth performance, antioxidant capacity, liver function and toxin residues of growing?finishing pigs fed diets contam?inated with aflatoxin B1( AFB1). Twenty?eight healthy Duroc×Landrace×Yorkshire growing?finishing pigs with average body weight of (38.06±0.27) kg were randomly assigned to 4 groups with 7 replicates per group and 1 pig per replicate according to similar body weight. The 4 group were control group ( basal diet) , AFB1 group (280 μg/kg AFB1 ) , compound additive group Ⅰ( AFB1 diet+0.3% antioxidant compound additive) and compound additive groupⅡ( AFB1 diet+0.3% intestinal health compound additive) , respectively. The experi?ment lasted for 102 days. The results showed as follows: compared with control group, average daily gain (ADG) at 51 to 75 kg was significantly decreased ( P<0.05) , plasma total superoxide dismutase ( T?SOD) activity was significantly decreased and plasma malondialdehyde ( MDA) content was significantly increased at 135 kg ( P<0.05) , plasma glutamic oxaloacetic transaminase ( GOT) activity was significantly increased at 100 kg ( P<0.05) , and liver index, AFB1 and aflatoxin M1( AFM1) contents in liver and kidney and AFB1 content in longissimus dorsi of growing?finishing pigs in AFB1 group were significantly increased ( P<0.05). Compared with AFB1 group, ADG at 51 to 75 kg was significantly increased ( P<0.05) , plasma T?SOD activ?ity was significantly increased at 135 kg ( P<0.05) , plasma MDA content and GOT activity were significantly decreased at 100 kg ( P<0.05) , and AFM1 content in kidney and AFB1 content in longissimus dorsi of grow?ing?finishing pigs in compound additive group Ⅰ were significantly decreased ( P<0.05 ). Compared with AFB1 group, plasma T?SOD activity was significantly increased at 135 kg ( P<0.05) , plasma MDA content was significantly decreased at 100 and 135 kg ( P<0.05) , and plasma GOT activity at 100 kg of growing?fin?ishing pigs in compound additive group Ⅱ was significantly decreased ( P<0.05 ). In conclusion, dietary 280 μg/kg AFB1 can reduce growth performance and body antioxidant capacity, increase tissue AFB1 residue, and lead to liver function of growing?finishing pigs damaged. Adding 0.3% antioxidant compound additive can significantly reduce AFB1 residue in tissue, improve body antioxidant ability, and effectively relieve the ad?verse effects of AFB1 on growth performance and liver function of growing?finishing pigs. Adding 0.3% intesti?nal health compound additive can significantly improve body antioxidant capacity and alleviate AFB1 damage to liver of growing?finishing pigs.[ Chinese Journal of Animal Nutrition, 2019, 31(10) :4691?4700]关键词
