摘要
试验选取杜长大三元杂交猪44头,随机分成试验组和对照组,每组3个重复。试验组和对照组分别采用生物发酵床技术饲养及传统方式饲养,研究两组猪在小猪阶段(20~60kg)和大猪阶段(60~120kg)的生长性能差异及对猪舍环境的影响。结果表明:试验组和对照组在中猪阶段的日增重分别为770.8g和741.7g,差异显著(P<0.05),料肉比分别为2.1和2.24,差异显著(P<0.05),且试验组较对照组节省饲料成本21元/头,经济效益较明显;而在大猪阶段2种饲养模式对猪的生长性能影响较小。采用发酵床技术饲养,栏舍温度较传统方法饲养的栏舍提高了3.1℃。因此,南方地区秋冬季节中猪阶段适合采用发酵床养殖,以提高其生长速度,同时降低料肉比。
Experimental selection of 24 du grew sanyuan hybridization pigs,divided into two groups at random,each group and the two repeated. Test bed by fermentation technology with traditional methods,control,compare two sets of pigs in the pig stage (2060 kg) and big pig stage (60120 kg) production performance. Results:in the first stage and the 770.8 g respectively the plecata g and 741.7 g,significant difference (P〈 0.05),respectively,and the flesh than 2.1 2.24,significant difference (P〈0.05) group is obvious effect,increase in saving feed costs $21 in pig head in that stage,raising pigs can improve fermentation bed,reduce the cost of breeding production performance. In a big pig raising two stages of performance,in a big pig breeding stage that bed,fermentation technology in improving pig raising production performance without the advantages.
