Abstract

Abstract The effect of feeding a diet containing 25% millet grain on performance and plasma metabolic profile was evaluated in weaned piglets during 21 days trial. A total of 40 pigs with an 8.14±1.08 kg average body weight (BW) was weaned at 28±3 days of age and divided into the control group (C) and the experimental group (M). The C group (n=20) received a conventional diet based on the corn-triticale-soybean meal while in the M group (n=20) received 25% millet grain cv. Marius replaced triticale (2 replicates per group). At the end of the post-weaning period, the performances (BW; average daily feed intake, ADFI; average daily gain, ADG; feed: gain ratio, F: G ratio) and plasma metabolic profile (lipid, protein, enzyme, mineral) were evaluated. A slow, but not significant increase was observed for the BW (+6%), ADG (+12%), ADFI (+5%) and F: G ratio (+7%) of pigs fed M diet. No effect (P>0.05) of dietary treatment on plasma metabolic profile was observed. However, the concentrations of triglyceride (-15%, P=0.089), total cholesterol (-14%, P=0.060) and aspartate aminotransferase enzyme activity (-16%, P=0.095) tended to decreased while inorganic phosphorus (+11%; P<0.04) had increased in the M vs. C diet. The present study indicated that the replacement of 25% millet grain to triticale in weaned piglet’s diet, maintains the performances and blood plasma parameters within the physiological ranges, beneficial to the health status.
在断奶仔猪日粮中添加谷子:对生产性能和健康状况的影响
在21 d的试验中,研究了添加25%谷粒对断奶仔猪生产性能和血浆代谢的影响。选取平均体重为8.14±1.08 kg的28±3日龄断奶仔猪40头,分为对照组(C)和试验组(M),其中C组(n=20)饲喂以玉米-小黑麦-豆粕为基础的常规饲粮,M组(n=20)饲喂25%谷粒cv的饲粮。马吕斯代替小黑麦(每组2个重复)。断奶后末,断奶仔猪的生产性能(体重;平均日采食量,ADFI;平均日增重;料重比(F: G比)和血浆代谢谱(脂质、蛋白质、酶、矿物质)。M饲粮对猪的体重(+6%)、平均日增重(+12%)、平均日增重(+5%)和料重比(+7%)有缓慢但不显著的提高。饲粮处理对血浆代谢谱无影响(P < 0.05)。甘油三酯(-15%,P=0.089)、总胆固醇(-14%,P=0.060)和天冬氨酸转氨酶活性(-16%,P=0.095)呈下降趋势,无机磷(+11%;P<0.04)增加。本研究表明,在断奶仔猪日粮中以小黑麦替代25%的谷子,可使断奶仔猪的生产性能和血浆参数维持在生理范围内,有利于仔猪的健康状态。
