Effects of Different Enzyme Complexes on the Metabolic Rate of Nutrients,Slaughter Performance and Intestinal Development of Newborn Broiler Chicks
To examine how various enzyme complexes added to dietary feeds impact the metabolic rate of nutrients,slaughter performance,and intestinal development of newborn broiler chicks,an one-way completely randomized design was employed to select 390 healthy Ross broiler chicks at 1 day old to randomly divide into 5 groups,each with 6 replicates,and one replicate for every 13 chicks.The experiment lasted for a total of 42 days.The results indicated that all enzyme complexes had a positive impact on the nutritional metabolic rate of broilers when compared to the control group.Notably,the enzyme preparation group Ⅳ showed significant improvements in the digestibility of Ca,P,CP,DM,NDF,and ADF.Furthermore,the enzyme preparation groups Ⅰ,Ⅱ,Ⅲ,and Ⅳ all demonstrated significant enhancements in the digestibility of Ca,P,CP,DM,NDF,and ADF,with the most effective results observed in the enzyme preparation group Ⅳ.It suggested that incorporating various enzyme preparations could enhance the nutritional metabolism and slaughter performance of broilers,while also promoting the growth and development of their intestinal tract.Notably,the enzyme preparation group Ⅳ exhibited the most significant feeding effect,with the enzyme preparation group Ⅲ following closely behind.
