Effects of Dietary Canola Meal Level on Proformance, Egg Quality, Trimethylamine Content in Egg Yolk of Flavin-Containing Monooxygenases 3 Genotype Laying Hens
摘要
Abstract
This experiment was conducted to investigate the effects of dietary Canola meal level on performance,egg quality,and trimethylamine (TMA) content in egg yolk of flavin-containing monooxygenases 3 (FMO3) genotype laying hens.A total of 336 FMO3 genotype brown shell laying hens,consisting of 48 hens of AA genotype,144 hens of AT genotype and 144 hens of TT genotype,were used in this study.Hens with AT and TT genotypes were randomly assigned to 4 groups with 6 replicates per group and 6 birds per replicate,and those with AA genotypes were randomly assigned to 4 groups with 6 replicates per group and 2 birds per replicate.The laying hens in four groups were fed a basal diet supplemented with 0 (control),7％,14％ and 21％ Canola meal,respectively.The experimental period lasted for 6 weeks.The results showed as follows:1) dietary Canola meal level,FMO3 genotype and the interaction of dietary Canola meal level and FMO3 genotype significantly affected average daily intake of laying hens (P＜0.05),but had no significant effects on average egg weight and the ratio of feed to egg (P＞0.05).The average daily feed intake in 14％ and 21％ Canola meal level groups was significantly lower than that in control group (P＜0.05).The average daily feed intake and egg production in AA genotype group were significantly lower than those in the other genotype groups (P＜ 0.05).2) Dietary Canola meal level,FMO3 genotype and the interaction of dietary Canola meal level and FMO3 genotype had no significant effects on egg-shape index,eggshell strength,albumen height and Haugh unit of laying hens (P＞0.05).But dietary Canola meal level had significant effect on the value of egg yolk color (P＜0.05),and the value of egg yolk color in 21％ Canola meal level group was significantly lower than that in the other groups (P＜0.05).3) Dietary Canola meal level,FMO3 genotype and the interaction of dietary Canola meal level and FMO3 genotype had significant effect on TMA content in egg yolk of laying hens (P＜ 0.05).The TMA content in egg yolk was improved with increasing dietary Canola meal level,and TMA content in egg yolk in 21％ Canola meal level group was significantly higher than that in the other groups (P＜ 0.05).The TMA content in egg yolk in TT genotype group was significantly higher than that in AA and AT genotype groups (P＜0.05).According to the regression equation of the TMA content in egg yolk of laying hens (Y) and dietary Canola meal level (X):Y=25.457 0X+2.852 0 (R2 =0.976 5,TT genotype),Y=7.685 7X+ 1.943 0 (R2 =0.952 5,AA genotype),dietary Canola meal level should be lower than 4.62 ％ (TT genotype hens) or 26.76％ (AA genotype hens) to make the TMA content in egg yolk lower than the estimated human olfactory threshold.The results suggest that when laying hens with TT genotype were fed the diet supplemented with Canola meal do not product fishy eggs,hens with AA and AT genotype will not product the fishy eggs,too.Thus,dietary Canola meal level lower than 4.62％ can not make laying hens with TT genotype product fishy eggs,and has no negative effects on performance and egg quality.关键词
