食物组分差异对树麻雀能量代谢及消化道形态结构的影响
Food composition differences influencing tree sparrow energy metabolism and its digestive tract structure
摘要
Abstract
This experiment was conducted to invesigate the effects of different food components on the physio-logical and biochemical indexes and digestive tract of small birds (Passer montanus), for understanding the survival strategy of P. montanus through self-regulation in response to adverse changes in environmental condi-tions. The birds were randomly divided into three groups: a control group(fed with millet-Setaria italica), a grass seed group(fed with grass-Echinochloa crusgalli seed), and a mealworm group(fed with mealworms-Tenebrio molitor).The birds have been domesticating for four weeks until the relevant indicators were detected, such as the basal metabolic rate(BMR)and body mass, organ quality of fresh and dry weight, body fat mass fraction,glycogen content,length of the digestive tract and the digestive tract mucous membrane layer thickness and height,width,cross-section of the intestinal wall.Results showed that the basal metabolic rates of the birds in the three groups(control group, grass seed group, mealworm group)were increased by 0.14, 0.35 and 0.11 mL·g-1·h-1respectively compared with the first week, and it was higher in the grass seed group than those in the other two groups (P<0.05). Body mass of the birds were all extremely significantly different between groups(P<0.01). Organ fresh weight of the large intestine, small intestine, duodenum and rectum were ex-tremely significantly higher in the grass seed group than those in the grass seed group and control group(P<0.01).Dry weight of duodenum and muscle stomach of the birds in the mealworm group were extremely signifi-cantly higher than those in the grass group and control group(P<0.01), while dry weight of the colon and rectum in control group were extremely significantly higher than those in the grass group and mealworm group (P<0.01). Digestible energy and digestibility of the birds in the mealworm group was significantly higher than those in the grass group(P<0.01). The length of large intestine, small intestine, duodenum of the birds were extremely significant difference among the three groups(P<0.01).The heights of large intestinal villus in the grass seed group and mealworm group were extremely significantly different with those in the control group (P<0.01), and the height and mucosal layer thickness of small intestine and duodenum villus in the control group and grass seed group were all extremely significantly different with those in the mealworm group(P<0.01). The differences of food component is one of the important environmental factors that would influence energy metabolism and digestive tract morphological structure of P.montanus.关键词
