Effects of Pfaffia paniculata Leaf Meal on Growth Performance,Antioxidant and Immune Function of Lingshan Chickens
摘要
Abstract
[Objective]This experiment was conducted to investigate the effects of dietary supplementation of Pfaffia paniculata leaf meal on the growth performance,nutrient metabolism,antioxidant capacity and immunity function of Lingshan chickens.[Method]A single-factor completely randomized design was employed.A total of 240 healthy 1-day-old female Lingshan chickens with similar body weight were randomly divided into control group(fed with basal diet)and three groups with 1.00％,2.00％and 3.00％of Pfaffia paniculata leaf meal.Each group consisted of 6 repetitions,with 10 chickens in each repetition.The pre-test period was 7 days and the formal test period was 35 days.At the end of the experiment,the body weights of the test chickens were measured and the feed intake was recorded on a per-replicate basis.The growth performance was also statistically analyzed.For each replicate,2 chickens were randomly selected for blood sampling and slaughter.The thymus,spleen,and bursa of Fabricius were collected,and the serum biochemical,antioxidant and immune indicators were measured.The immune organ indices were also statistically analyzed.On the last 4 days of the experiment,the feces of the experimental chickens were collected using the total feces collection method,and the nutrient contents were determined.The apparent metabolic rate of nutrients were calculated.[Result]①Dietary supplementation with Pfaffia paniculata leaf meal had no significant effect on the average daily feed intake(ADFI),average daily gain(ADG),and feed-to-gain ratio(F/G)of Lingshan chickens(P＞0.05).However,the final body weight tended to increase in 1.00％and 2.00％addition groups(P=0.094).②The apparent protein metabolic rate in the addition group with 2.00％Pfaffia paniculata leaf meal was significantly higher than that of control group and 1.00％addition group(P＜0.05),while there were no significant differences in the metabolic rates of other nutrients among the groups(P＞0.05).③The total protein content in serum of chickens in the addition groups with 1.00％and 2.00％Pfaffia paniculata leaf meal was significantly higher than that of control group and 3.00％addition group(P＜0.05),and the triglyceride content in the serum of chickens in each addition group was significantly lower than that of control group(P＜0.05).④Compared with control group,the serum superoxide dismutase(SOD)activity of chickens in the addition groups with 1.00％and 2.00％Pfaffia paniculata leaf meal significantly increased(P＜0.05).The content of malondialdehyde in serum of chickens in each addition group showed a decreasing trend,but the difference was not significant(P=0.061).⑤Compared with control group,the serum immunoglobulin G content of Lingshan chickens significantly increased after adding different levels of Pfaffia paniculata leaf meal to the diet(P＜0.05).The bursa of Fabricius index in 1.00％and 2.00％addition groups significantly increased(P＜0.05).[Conclusion]Dietary supplementation with Pfaffia paniculata leaf meal at appropriate levels could increase the apparent metabolic rate of crude protein,improve the lipid metabolism,and enhance the antioxidant capacity and immune function in Lingshan chickens.Under the conditions of this experiment,the supplementation level of 1.00％to 2.00％Pfaffia paniculata leaf meal showed better effects.关键词
