高温环境对家禽营养物质消化的影响
Effects of High Ambient Temperature on Nutrition Digestibility in Poultry
摘要
Abstract
High ambient temperature is an important factor that affects poultry production, which decreases the feed intake of poultry, induces the deleterious effect on growth rate of broilers and egg production, egg weight and body weight in laying hens.However, this negative effect of heat stress on growth rate and production is not all due to reduced feed intake, production performance still significantly reduces under the high environment temperature even in the same condition of feed intake.This paper mainly reviewed the effect of high temperature on nutrition digestibility, metabolic energy values of diet, digestive enzyme activity, feed passage rate and gut structure in poultry to provide scientific basis for understanding the effects of high temperature on digestion and absorption function of poultry and its nutritional regulation.[Chinese Journal of Animal Nutrition,关键词
