饲粮蛋白质水平及组成与早期断奶仔猪腹泻密切相关。饲粮蛋白质不仅要满足仔猪的营养需要以保持仔猪正常的生长性能,而且要有利于克服高蛋白水平对仔猪的不良作用。   Papadopoulos等(1987)报道,低蛋白质水平的血球蛋白粉饲粮可以有效的减少早期断奶仔猪腹泻的发生,董国忠等(1996)报道,饲粮蛋白水平的降低,可以使饲粮中抗原作用降低,同时可以降低蛋白质在大肠中的腐败作用,减少仔猪腹泻的发生。但不能通过降低蛋白质水平来减少仔猪腹泻的发生,简单地降低蛋白质水平有可能影响仔猪对蛋白质和氨基酸的需要量,可以通过平衡多种必需氨基酸来降低饲粮蛋白质水平,一般情况下,断奶仔猪饲粮适宜蛋白质水平应控制在16%~19 %之间。蛋白质来源的差异也会不同程度的影响仔猪的腹泻发生。早期断奶仔猪由于消化道及其酶系统发育不健全,因此不适应植物性蛋白质高的饲粮,吴世林等(1993),Newby(1984)报道,仔猪饲粮中植物蛋白比例太高引起消化不良和腹泻。仔猪可较好利用奶蛋白和高消化性的动物蛋白质,如果经济允许时,可以在仔猪饲粮中添加鱼粉、脱脂奶粉、喷雾干燥血粉(SDBM)和喷雾干燥猪血浆蛋白粉(SDPP)等,在这血球蛋白粉几种动物蛋白中,以SDPP效果最佳,SDBM次之。大量的研究表明,早期断奶仔猪饲粮中添加2%~10巩的SDPP均能提高仔猪采食量、日增重和饲料利用率(Gatnau等1990,1991;Richert等,1992;Kats等,1994;Touchette等,1997)。此外,由于蛋白质是饲粮中主要抗原物质的来源之一,应注意饲料蛋白质的品质,减少饲料中的抗原因子和过敏性物质,防止异常性免疫反应的发生。
