Effects of Fenugreek Powder on Growth Performance, Meat Quality, Immune Organ Indexes, Serum Antioxidant and Biochemical Parameters of Broilers
摘要
Abstract
The current study was conducted to investigate the effect of fenugreek powder (FP) on growth performance,meat quality,immune organ indexes,serum antioxidant and biochemical parameters of broilers.A total of 320 one-day-old Arbor Acres broilers were randomly allotted into 4 groups with 8 replicates per group and 10 broilers per replicate.Four levels of FP [0(control),3%,6% and 9%] were used into experiment diets and all of these diets were at a same nutrient level.The experiment lasted for 42 days.The results showed as follows: 1) at 1 to 21 days of age,the average body weight and average daily gain of 6% and 9% FP groups were significantly lower than those of control group (P<0.05),the average daily feed intake of 9% FP group was significantly lower than that of control group (P<0.05),and the ratio of feed to gain of 3% FP group was significantly lower than that of control group (P<0.05).At 22 to 42 days of age and 1 to 42 days of age,dietary FP level did not significantly affect the growth performance of broilers (P>0.05).2) The drip loss and pressure loss of breast meat of 9% FP group were significantly lower than those of control group (P<0.05).Dietary FP level did not significantly affect the pH45 min,pH24 h,shear force and cooking loss of breast meat (P>0.05).3) The spleen index at 21 days of age of 6% FP group was significantly higher than that of control group (P<0.05).Dietary FP level did not significantly affect the thymus index,bursa of Fabricius index at 21 days of age and thymus index,spleen index,bursa of Fabricius index at 42 days of age (P>0.05).4) The serum total superoxide dismutase (T-SOD) activity at 21 days of age of 9% FP group was higher than that of control group (P>0.05),and significantly higher than that of 3% and 6% FP groups (P<0.05);the serum total antioxidant capacity (T-AOC) at 42 days of age of 6% FP group was significantly higher than that of other groups (P<0.05).Dietary FP level did not significantly affect the serum T-AOC and malondialdehyde (MDA) content at 21 days of age and serum T-SOD activity and MDA content at 42 days of age (P>0.05).5) The serum glutamic-oxalacetic transaminase activity at 21 days of age of 9% FP group was significantly higher than that of control group (P<0.05),the serum glutamic-oxalacetic transaminase activity at 42 days of age of 3% FP group was significantly higher than that of control group (P<0.05).Dietary FP level did not significantly affect the serum total protein,albumin,globulin,urea nitrogen content and albumin/globulin and glutamic-pyruvic transaminase activity at 21 and 42 days of age (P>0.05).In conclusion,FP can be used as a protein ingredient in broilers feeding,FP can improve the water holding capacity of muscle,promote immune organ development,and improve antioxidant capacity and enhance protein metabolism.The dietary suitable supplemental level of FP for broilers is no more than 3% at 1 to 21 days of age and no more than 6% at 22 to 42 days of age.关键词
