【摘要】：为研发肉鹅舍内养殖新技术,避免传统水禽生产造成的公共水体污染问题,研究开展了肉鹅的发酵床网上养殖试验,并与地面发酵床平养在舍内环境因子、生产性能和经济效益方面进行了对比。试验期为70 d。结果显示:随着肉鹅生长,舍内空气质量逐渐下降;同一采样时间点,气载活菌数、空气脂多糖浓度以及粉尘含量,发酵床网养均显著或极显著低于地面发酵床平养(P0.05或P0.01)。出栏时,发酵床网上养殖鹅群死亡率为4.13%、体重变异系数为10.67%,分别低于地面发酵床平养的6.16%和13.57%,且前者净利润率高出发酵床平养9.47个百分点。研究表明:在较低的饲养密度下,发酵床网上养殖模式能提供更好的养殖环境,可成为肉鹅旱养的一种新模式。
[Abstract]:In order to develop new breeding technology in meat goose house and avoid public water pollution caused by traditional waterfowl production, the fermentation bed net culture experiment of meat goose was carried out, and the environmental factors in the house were equalized with the ground fermentation bed. The production performance and economic benefit are compared. The experimental period is 70 d. The results showed that with the growth of geese, the air quality in the house decreased gradually. At the same sampling time point, the number of living bacteria in air, the concentration of lipopolysaccharide in air and the content of dust in fermentation bed were significantly or extremely significantly lower than those in ground fermentation bed (P0.05 or P0.01). The mortality rate and the coefficient of variation of body weight were 4.13% and 10.67%, respectively, which were lower than 6.16% and 13.57% of ground fermentative bed, respectively. The net profit margin of the former was 9.47% higher than that of fermentation bed. The results showed that under the condition of low feeding density, the fermentative bed net culture model could provide a better breeding environment, and could be a new model for dry breeding of meat geese.
