【摘要】：鉴于北京市水资源匮乏,为有效评估北京市生猪养殖业的用水量现状及浪费情况,寻求节水途径,同时减轻污水处理压力,分别于北京市大兴区和房山区各选择一猪场进行了不同阶段猪舍的用水量监测。结果显示,试验期内,大兴某猪场一栋产房内平均用水量(123.47±66.17)L/(hd·d),一栋保育舍内平均用水量(5.17±3.15)L/(hd·d),一栋空怀妊娠舍内平均用水量(22.74±6.44)L/(hd·d),两栋育肥舍内平均用水量分别为(15.51±11.89)L/(hd·d)和(25.31±20.87)L/(hd·d);除产房外,冬夏季用水量差别极显著(P0.01)。房山某猪场空怀后备猪舍2015年5月~10月日用水量为30~40L/(hd·d),11月~次年6月日用水量为20~30L/(hd·d),日用水量减少幅度约为25.0%~33.3%,饲养管理在节水中作用较大;该猪舍日用水量83.0%的数据分布在10~40L/(hd·d),鉴于某些天数用水量过大,仍存在较大的节水空间。除大兴某猪场的产房外,其余各猪舍的用水量监测结果基本符合国内对相应猪群的建议水量。
[Abstract]:In view of the scarcity of water resources in Beijing, in order to effectively assess the current situation of water consumption and waste in the pig breeding industry in Beijing, we seek ways to save water and at the same time reduce the pressure on sewage treatment. In Daxing District and Fangshan District of Beijing, the water consumption of pigsty was monitored at different stages. The results showed that, The average water consumption in a parturition room of a pig farm in Daxing was 123.47 卤66.17 / L / d, the average water consumption in a nursery was 5.17 卤3.15 / L / d, and the average water consumption in an empty pregnancy house was 22.74 卤6.44 / L / d. The average water consumption in the two fattening houses was 15.51 卤11.89 / L / d and 25.31 卤20.87 / L / d, respectively. The difference of water consumption in winter and summer was very significant (P 0.01). The daily water consumption of a hog farm in Fangshan from May 2015 to October was 30 ~ 40 L / L / d, and from November to November, the daily water consumption was 20 ~ 30 L / L / d ~ (th), and the decrease of daily water consumption was about 25.0% ~ 33.3. Raising and management played an important role in saving water. The daily water consumption of the hog house is 83.0%, which is distributed in 10 ~ 40 L / d. In view of the large amount of water consumption in some days, there is still a large room for water saving, except for the delivery room of a pig farm in Daxing. The monitoring results of water consumption of the other piglets basically accord with the domestic recommended water quantity for the corresponding pig herd.
