摘要
本研究对12头9周龄的大白×长白杂交断奶猪进行了为期42天的试验,以确定它们在饲喂不同水平的发酵玉米碾磨废料(FMMW)时的生产性能。分别配制4种断奶日粮,其中t1、t2、t3和t4分别以60%、0%、55、5%、50、10%的比例添加玉米和FMMW;分别是45.15%其他成分在四种饮食中保持不变。采用完全随机设计(CRD)试验,将断奶仔猪随机分为4组,每组3头猪,每组1个重复。42 d处理结束时,t1、t2、t3和t4的日采食量分别为315、318、321和323g, t1、t2、t3和t4的日增重分别为95、93.2、91和88.9。T1、t2、t3和t4的饲料系数分别为3.32、3.42、3.53和3.63。试验结果表明,各处理组采食量和日增重差异不显著(p 0.05)。然而,对照猪的饲料转化率显著提高(p动物生产研究进展Vol. 3 (1) 2007: pp. 23-27)
A 42-days study was carried out with twelve (12) nine week old large white x landrace cross weaner pigs to determine their performance when fed with graded levels of fermented maize milling waste (FMMW) resulting from pap production. Four weaner diets were formulated such that diets T 1, T 2, T 3 andT 4 contained maize and FMMW at the proportions of 60, 0%, 55, 5%, 50, 10%; and 45, 15% respectively. Other ingredients remained constant for the four diets. The diet were offered to weaner pigs, which were randomly divided into four (4) groups of 3 pigs each, with each pig constituting a replicate in a completely randomized design (CRD) experiment. At the end of 42-days treatment, the daily feed intake stood at 315, 318, 321 and 323g for T 1, T 2, T 3 and T 4 respectively, while the daily weight gain stood at 95, 93.2, 91 and 88.9 for T 1, T 2, T 3 and T 4 respectively. The feed conversion ratios were 3.32, 3.42, 3.53 and 3.63 for T1, T 2, T 3 and T 4 respectively. The results of the experiment showed no significant (p 0.05) difference in feed intake and daily weight gain for the treatment groups. However the feed conversion ratio of the control pigs was significantly (p Animal Production Research Avancees Vol. 3 (1) 2007: pp. 23-27
