Effect of Cereal Type and Enzyme Addition on Performance, Pancreatic Enzyme Activity, Intestinal Microflora and Gut Morphology of Broilers
The effects of grain and carbohydrase enzyme supplementation were investigated on digestive physiology of chickens. A total of 625 one-day-old chicks (Ross 308) were randomly assigned to five treatments in a completely randomized design. Treatments included two different types of grains (wheat, and barley) with or without a multi-carbohydrase supplement. A corn-based diet was also considered to...
متن کاملThe role of exogenous enzymes in promoting growth and improving nutrient digestibility in poultry
The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...

An experiment was conducted to evaluate the effect of different levels of germinated barley (GB) on live performance and carcass traits in broiler chickens. The experiment lasted for 5 weeks starting from 7 days of age and ending at 42 days of age. Chicks (Ross 308) were fed six dietary treatments including a corn–soy diet (corn diet), a barley–soy diet (barley diet), a barley diet plus enzymes...
