Effects of Anise Essential Oil on Growth Performance, Nutrient Apparent Digestibility and Fecal Microbial Number of Piglets
摘要
Abstract
This experiment was conducted to study the effects of anise essential oil on the growth performance, nutrient apparent digestibility and fecal microbial number of piglets. A total of three hundred and twenty 40?day?old Duroc×Large White×Landrace piglets with the similar body weight about 10 kg were randomly alloca?ted into 5 groups with 8 replicates per group and 10 piglets per replicate. Piglets in control group were fed a basal diet, piglets in test group 1 were fed the basal diet supplemented with antibiotics ( chlortetracycline 75 mg／kg+bacitracin 10 mg／kg) , piglets in test group 2 were fed the basal diet supplemented with antibiotics ( chlortetracycline 75 mg／kg+bacitracin 10 mg／kg) and anise essential oil ( 300 mg／kg) , and piglets in test group 3 were fed the basal diet supplemented with anise essential oil ( 300 mg／kg). The test period was 28 days. The results showed as follows: 1) the average daily gain ( ADG) of piglets in the test groups with antibi?otics and／or anise essential oil was significantly higher than that in the control group ( P＜0.05) ; the ADG of piglets in the test group 3 was significantly higher than that in the test group 2 ( P＜0.05) , but there was no sig?nificant difference in ADG between test group 1 and test group 3 ( P＞0.05). The feed to gain ratio ( F／G) in the test groups was significantly decreased compared with the control group ( P＜0.05).2) The apparent digest?ibility of dry matter in the test group 2 and test group 3 were significantly higher than that in the control group ( P＜0.05) , the apparent digestibility of ether extract in the test groups was significantly higher than that in the control group ( P＜0.05). 3) The number of fecal lactic acid bacteria in the test group 3 was significantly high?er than that in the test 2 group ( P＜0.05 ). In conclusion, the addition of anise essential oil has the similar effects with antibiotics on increasing the ADG, decreasing the F／G, improving the apparent digestibility of dry matter and ether extract, and is more beneficial for the intestinal health of piglets. Therefore, the anise plant es?sential oil has the potential to replace antibiotics.[ Chinese Journal of Animal Nutrition, 2019, 31(11) :5238?5244]关键词
