摘 要:试验选用23日龄断奶、体重接近的杜长大三元杂交猪90头,以常规水泥地面饲养方式为对照,研究了发酵床饲养方式对猪舍环境的影响。结果表明,发酵床饲养方式猪舍温度显著高于常规水泥地面饲养方式(P<0.05),猪舍空气中PM10浓度显著低于常规水泥地饲养方式(P<0.05),氨气和H2S浓度极显著低于常规水泥地饲养方式(P<0.01)。说明发酵床饲养方式能改善猪舍内环境。The 90 pigs (Duroc)〈 Landrace )〈 Yorkshire) weaned in 23 days were selected, and divided into two groups. The conventional concrete floor feeding was used in control group, and the effect of fermentation-bed on environment in pig house was studied. The result indicated that the temperature in fermentation-bed was significantly higher than that in control group (P〈0. 05), the air PMIO density, the concentration of ammonia and H2 S in fermentation-bed were significantly lower than that in control group (P〈0. 05) ;It showed the fermentation-bed feeding could improve the environment in pig house.
