限食对树麻雀能量代谢及消化道形态结构的影响
Influence of diet restriction on the energy metabolism and digestive tract morphology in Passer montanus
摘要
Abstract
In order to explore the influence of diet restriction on the physiological and biochemical indexes and digestive tract morphology ofthetree sparrow ( Passer montanus ) .According to body weight ,the sparrowswere divided into the control group ,semi starvation group ,and aquarterstarvation group ,re-spectively .After hunger domestication ,the changes of the physiological and biochemical indexes anddi-gestive tract morphology were determined .The study found that with the increase of food restriction de-gree ,in thesemi starvation group and aquarterstarvation group ,the body weight ,Basal metabolic rate (BMR)fraction ,body fat mass fraction ,glycogen content ,theheightand width of the gastrointestinal vil-li ,the cross - sectional area of the digestive tract showed a decline trend when compared withthe control group ,while the fresh weight of organ ,digestive energy ,digestibility and the length of digestive tract have a trend of increasing .These results indicate that the diet restriction is one of an important environ-mental factors that affect the morphology of digestive tract in tree sparrow .Under the condition of food restriction ,tree sparrowsreduce the body weight ,increase energy intake ,modify the structure of diges-tive tract ,consume energy reserves of the body and reduce energy consumption toalleviate the survival pressure caused by food shortages .关键词
