摘要
通过对照组、添加沼渣Ⅰ组、添加沼渣Ⅱ组共计18头杜长大三元杂交猪的肥育试验,研究饲料中添加沼渣对猪的肥育效果.结果表明:对照组、添加沼渣Ⅰ组、添加沼渣Ⅱ组达到相同出栏体质量时肥育期分别为99、107、112d;20-90kg阶段.对照组和添加沼渣Ⅰ组日增质量分别为710.10、655.14g/d,极显著高于添加沼渣Ⅱ组(625.89g/d)(P〈0.01);对照组和添加沼渣Ⅰ组料肉比(分别为3.50和3.48)显著高于添加沼渣Ⅱ组(3.46)(P〈0.05);添加沼渣Ⅰ组和Ⅱ组每头猪的饲料成本分别比对照组节约了17.78元和25.25元.
Feeding trial was carried with 18 growing and finishing hybride pigs(duroc× landrace× yorkshire) which were assigned into one control group and two test groups(adding biogas residue group Ⅰ and adding biogas residue group Ⅱ ) to study its effect on fattening performance in pigs, The results showed that,the finishing period of the three groups (control group, adding biogas residue group Ⅰ and adding biogas residue group Ⅱ ) getting the same body weight for sale were 99d, 108d and 111d respectively. In the stage of 20-90 kg,the average daily gain of control group (710.10 g/d)and adding biogas residue group Ⅰ (655.14 g/d )were extremely significantly higher than that of adding biogas residue group Ⅱ (625.89 g/d)(P〈0.01),the feed convertion ratio of control (3.50) and biogas residue group Ⅰ (3.48) were significantly higher than that of adding biogas residue group Ⅱ (3.46)(P〈0.05). The feed cost of adding biogas residue group Ⅰ and group Ⅱ for each was fewer than control group for 17.78 yuan and 25. 25 yuan respectively.
