发酵棕榈粕对肉用繁殖母牛养分表观消化率和血清生化指标的影响
Effects of fermented palm kernel meal on nutrient apparent digestibility and serum biochemical indexes in beef breeding cows
摘要
Abstract
This experiment aimed to screen the optimal formula for fermented palm kernel meal and investigate the effects of replacing part of the concentrate with fermented palm kernel meal on nutrient apparent digestibility and serum biochemical indexes in beef breeding cows.Experiment 1:Ten groups were set up,each with three replicates,500 g per replicate,including one control group(unfermented palm kernel meal)and nine treatment groups(group T1 to group T9).The treatment groups were fermented at 37℃in the dark for 72 hours using three different microbial-enzyme combinations applied to three palm kernel meal formulas,to screen for the best fermentation combination.Experiment 2:Ninety healthy Simmental breeding cows with similar age,parity,and crossbreeding background were randomly divided into three groups,with three replicates per group and 10 cows per replicate.The control group was fed a basal diet.Experimental group Ⅰ replaced part of the concentrate in the basal diet with 6%self-made fermented palm kernel meal,and the experimental group Ⅱ replaced part with 6%commercially available fermented palm kernel meal.The pre-test period was 14 days,and the formal test period was 90 days.The results showed that the crude fiber(CF)content in group T2 was extremely lower than in the control group(P<0.01),and the neutral detergent fiber(NDF)content was significantly lower than in the control group(P<0.05).The apparent digestibility of crude protein(CP)in experimental group Ⅰ was significantly higher than in the control group and experimental group Ⅱ(P<0.05),and the apparent digestibility of NDF was extremely higher than in the control group and experimental group Ⅱ(P<0.01).The serum urea nitrogen(BUN)content in experimental group Ⅰ was significantly lower than in the control group and experimental group Ⅱ(P<0.05).The study shows that the optimal fermentation formula is 60.0%palm kernel meal+10.0%corn flour+10.0%wheat bran+0.5%microbial-enzyme agent(Pediococcus acidilactici+Saccharomyces cerevisiae+protease+xylanase)+20.0%water.Adding 6%self-made fermented palm kernel meal to the diet of beef breeding cows can improve nutrient apparent digestibility without adverse effects on serum biochemical indexes.关键词
