腹泻和FUT1基因型对仔猪断奶后增重的影响

断奶应激常常导致仔猪腹泻甚至生长迟滞,仔猪个体与个体间在断奶后的表现存在差异.为了研究影响断奶后14 d内仔猪增重的因素,我们用140头同日出生的杂交仔猪进行了试验.仔猪在28日龄断奶,在断奶后14 d内每日记录每头猪的腹泻情况,并在断奶后3、7和14 d分别进行了称重.检测了每头猪FUT1(M307G/A)的基因型.统计分析结果表明,FUT1基因型与腹泻的天数相关,而平均日增重与FUT1基因型无关;腹泻的天数对平均日增重无显著影响;性别间断奶后表现差异显著.

Effects of Diarrhea and Genotype of FUT1 Gene on the Weight Gain During Weaning Stress in Piglets

To investigate the effect of the genotype of FUT1 at M307 G/A site on post-weaning diarrhea and weight gain,ag well as the relationship of post-weaning diarrhea with growth performance in pigs,a experiment with 140 cross pigs were carried out.Pigs were weaned at 28 d of age.During day 1～14 after weaning,the diarrhea status was recorded twice at morning and afternoon respec-tively every day.Pigs were weighed at birth,weaning,day 3,7 and 14 post-weaning.The genotype of FUT1(M307G/A)was detected by PCR-RFLP for each individual.The statistic analysis results showed that the genotype of FUTl WSS related significantly to diar-rhea days,while the average daily weight gain was not affected by the diarrhea days or the genotype of FUT1 gene.
