| 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、112 d;20~90 kg阶段,对照组和添加沼渣Ⅰ组日增质量分别为710.10、655.14 g/d,极显著高于添加沼渣Ⅱ组(625.89 g/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.

| Abstract: | 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 Ⅰand 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 Ⅰand 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. |
