1980年12月～1981年4月,我们在东郊农场苇沟猪场选择了条件相似的秋产苏荣杂种仔猪54头,随机区分6组,每组9头。进行同一能量(3100大卡),不同蛋白水平(高蛋:16、14、13%;低蛋:13、11、10%)下分别添加腐钠(0.5%/风干饲料)与腐钠+脂肪酸脲的2×3复因子试验。试验结果表明:在高能高蛋白水平下添加腐钠比高能低蛋水平下添加的效果好:(1)在高能高蛋白水平下添加0.5%纯腐钠可提高日增率4.18%(P>0.05),节省混合料0.11%kg(3.3%)/增重。特别在体重20～5kg 阶段时可提高日增率11.92%(P>0.05)节省混合料0.21kg(6.89%)/增重。(2)在高能高蛋水平下添加腐钠脂肪脲不起作用。(3)在高能低蛋水平下添加腐钠提高日增率0.57%。腐钠脂肪脲组增长1.32%,基本上不起作用。但在低能低蛋水平下能起一定的作用。
From December 1980 to April 1981, we selected 54 hybrid piglets of the same yield in Weiguogou Farm, Eastern Suburb, and randomly divided 6 groups of 9 pigs each. At the same energy (3100 calories), different protein levels (high egg: 16,14,13%; low egg: 13,11,10%) were added saponification (0.5% / air dried feed) Urea 2 × 3 complex factor test. The results showed that adding sodium into the high energy and high protein level had better effects than high energy and low energy level: (1) Adding 0.5% pure sodium into the high energy and high protein level increased the rate of increase by 4.18% (P> 0.05 ), Save 0.11% kg of mixture (3.3%) / weight gain. Especially in the body weight of 20 ~ 5kg stage can increase the rate of increase of 11.92% (P> 0.05) to save 0.21kg mixture (6.89%) / weight gain. (2) Adding sodium into the sodium sequestrants at high energy and high egg levels does not work. (3) Adding sodium into the high energy and low egg level to increase the rate of increase by 0.57%. Natrium fatty acid urea group increased 1.32%, basically does not work. But in the low energy low egg level can play a role.
