无氮饲粮中铬添加水平对大鼠器官指数、肠道黏膜形态及血清指标的影响
Effects of Chromium Supplemented Level in Nitrogen-Free Diets on Organ Indexes, Intestinal Mucosa Morphology and Serum Parameters of Rats
摘要
Abstract
This experiment was conducted to investigate the effects of different chromium propionate ( CrPro) level in nitrogen-free diets ( NFD) on organ indexes, intestinal mucosa morphology and serum parameters of rats.According to body weight, a total of 36 weaned Sprague Dawley ( SD) rats were allotted to 3 treatments with 6 replicates per treatment and 2 rats per replicate.Rats were fed a basal NFD ( control group) containing 0.08 mg/kg chromium ( Cr) , meanwhile, the basal diets supplemented with 0.2 or 1.0 mg/kg Cr from Cr for 21 days.The results showed that: 1) dietary supplemented with 0.2 mg/kg Cr significantly improved spleen index ( P<0.05) .2) Dietary supplemented with 1.0 mg/kg Cr significantly increased the ratio of villous height to crypt depth ( P<0.05) .3) Compared with the control group, dietary supplemented with 1.0 mg/kg Cr sig-nificantly improved serum albumin and uric acid contents ( P<0.05) , dietary supplemented with 0.2 mg/kg Cr significantly improved serum uric acid content ( P<0.05) .It is concluded that under NFD condition, the proper Cr supplementation has some effects on improving immune organs indexes, intestinal mucosa morphology and serum protein metabolism.关键词
