Carbohydrase inclusion in a corn-soybean diet improves broiler growth performance

چکیده
An experiment was conducted to evaluate the effect of diets with reduced energy level content, supplemented carbohydrase, on broiler performance and coefficient metabolizability nutrients. A total 720 one-day-old male Cobb-500 chicks were distributed in a completely randomized design, six treatments, eight repetitions 15 birds each. The treatments were: (1) positive control, basal diet meet requirements chickens (PC); (2) negative reduction 80 kcal kg-1 (NC); (3) NC + alphagalactosydase; (4) xylanase; (5) xylanase alphagalactosydase, (6) enzymatic blend (alphagalactosydase, xylanase, pectinase amylase). nutrient digestibility not improved by use enzymes. At 7 days age, broilers which fed enzymes showed lower feed intake (FI) better conversion ratio (FCR) than PC. Both resulted worse at 21, 35 42 old. alphagalactosydase isolated or combination, corn-soybean meal-based is effective improving growth energy-reduced diets.

The experiment was conducted to test the hypothesis that supplementing diets of lactating first parity sows with a mixture of carbohydrases (CS) improves lactation performance and second parity reproductive performance. The CS used in this study contained 7 units/g of α-1,6-galactosidase, 22 units/g of β-1,4-mannanase, β-1,4-mannosidase and trace amounts of other enzymes. Twenty primiparous sow...

A total number of 5520 female and 480 male breeders (Arbor Acres plus) at 42wks of age were used in a 10-week-trial to investigate the effect of an enzyme complex on the quality and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzy...

Epidermal growth factor (EGF), a protein known for its mitogenic and anti-apoptotic effects was fed to broiler chickens to evaluate growth performance, gastrointestinal measurements, and apparent retention (AR) of components upon challenge with Eimeria. A total of 216, d old male broiler chicks (Ross 708) were placed in cages (6 birds/cage) and allocated to treatments. The treatments were: 1) c...
