Effects of Microencapsulated Essential Oils and Organic Acids on Growth Performance, Immune Organ Indexes, Slaughter Performance, Meat Quality and Serum Biochemical Indexes of Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of microencapsulated organic acids and es-sential oils ( MOAEO) on growth performance, immune organ indexes, slaughter performance, meat quality, and serum biochemical indexes of broilers. A total of 300 one-day-old yellow-feathered male broilers were ran-domly divided into 5 groups with 5 replicates per group and 12 broilers per replicate. Broilers in groupⅠ( con-trol group) were fed a basal diet, broilers in group Ⅱ ( antibiotics group) were fed the basal diet added with 30 mg/kg bacitracin zinc and 6 mg/kg colistin sulfate, and the others in groupsⅢ, Ⅳ and Ⅴ were fed basal diet added with 150, 200 and 250 mg/kg MOAEO, respectively. The experiment lasted for 70 days. The re-sults showed as follows:1) at 1 to 21 days of age, compared with the control group, the average daily gain in group Ⅱ was significantly increased ( P<0.05) , the feed to gain ratio in group Ⅳ was significantly decreased (P<0.05), the spleen index in groups Ⅳ and Ⅴ was significantly increased (P<0.05), the serum uric acid content in groupⅤwas significantly decreased ( P<0.05) . 2) At 1 to 70 days of age, compared with the con-trol group, the feed to gain ratio in groupⅣwas significantly decreased ( P<0.05) , the spleen index in groupⅣ was significantly increased ( P<0.05) , the serum total protein content in groupsⅡandⅣwas significantly increased ( P<0.05) , the serum uric acid content in groupsⅡ and Ⅳ was significantly decreased ( P<0.05) , the breast muscle rate and leg muscle rate in group Ⅳ were significantly increased (P<0.05), the water loss rate of breast muscle in group Ⅳ was significantly decreased (P<0.05). 3) Compared with the antibiotics group, dietary MOAEO did not affect the growth performance, immune organ indexes, slaughter performance and serum biochemical indexes of broilers. In conclusion, dietary MOAEO addition can improve growth per-formance, immune organ indexes, slaughter performance, meat quality and serum biochemical indexes of broilers, and the suitable MOAEO addition is 200 mg/kg.关键词
