摘要
Abstract
This study aimed to evaluate the feasibility of completely replacing choline chloride with plant-derived natural choline substitutes and betaine(used alone or in combination)in broiler diets,and to investigate their effects on the production performance of broilers.A 3×3 factorial design was adopted in the experiment,where 2000 one-day-old male Cobb 500 broilers were randomly assigned to 10 dietary treatment groups with 10 replicates per treatment and 20 birds per replicate.The diets in each group were supplemented with different levels of natural choline,betaine or choline chloride,respectively:T1 served as the control group with no choline addition;T2,T3 and T4 were supplemented with 100,200 and 400 g/t of natural choline,respectively;T5 and T6 were supplemented with 200 and 400 g/t of betaine,respectively;T7 and T8 were supplemented with 480 and 960 g/t of choline chloride,respectively;T9 was supplemented with a combination of 100 g/t natural choline and 200 g/t betaine;T10 was supplemented with a combination of 200 g/t natural choline and 400 g/t betaine.The experimental period lasted for 42 days.The results showed that dietary treatments had a significant effect on the body weight of 42-day-old broilers(P<0.05).Broilers fed diets supplemented with 400 g/t betaine or 400 g/t natural choline had significantly higher body weights than those in the control group,the 200 g/t natural choline group and the betaine-supplemented groups(P<0.05).The optimal feed conversion ratio(FCR)was observed in broilers fed the diet with 100 g/t natural choline plus 200 g/t betaine,followed by those in the 200 g/t betaine group and the 200 g/t natural choline group.No significant difference was found among these three groups,while their FCR values were all significantly lower than those in the control group and the two choline chloride-supplemented groups(P<0.05).In addition,the cost per unit weight gain was lower in all treatment groups with exogenous choline supplementation compared with the control group,and the lowest cost was recorded in the group supplemented with 100 g/t natural choline combined with 200 g/t betaine.In conclusion,plant-derived natural choline substitutes and betaine can effectively replace synthetic choline chloride in broiler diets without impairing production performance.A synergistic effect may exist between these two additives,and their combined application at appropriate dosages is conducive to improving feed utilization efficiency and growth performance of broilers,thereby ultimately reducing the cost per unit weight gain and enhancing the economic benefits of broiler breeding.关键词
