【摘要】：研究设计了一种新型的饲料微生物发酵床,以200m~2的饲料微生物发酵床猪舍为例,猪舍的长20m,宽10m,高4.5m,垫料深度50cm。发酵床饲料垫料管理包括保持垫料一定的湿度(45%)和通气量(经常性翻耕),一般每3d将饲料发酵床表面垫料翻耙1次,猪的日常翻拱也有助于垫料的疏松。饲料发酵床饲养密度为每平方米4头小猪(20kg以下),2头中猪(20~50kg),1头大猪(50~100kg)。由于猪粪排泄不均匀,而猪翻拱仅可分散一部分猪粪,发酵床发酵饲料的管理还需人工处理,将集中的猪粪均匀地分散在垫料中。发酵床垫料中的发酵饲料可以提供猪所需饲料的30%,其他70%饲料可以通过添加常规饲料来补充,饲料可以直接撒在发酵床上供猪取食。以200 m~2饲料发酵床养殖实例,30d内,猪的平均初重36.4kg,末重为59.5kg,料肉比达2.7∶1,均匀度良好,无死亡。发病率为5%,主要表现为发烧,精神沉郁,食欲低下,经治疗均康复或自然康复。本试验取得的经验为饲料发酵床的进一步研究、推广提供了基础。
[Abstract]:A new type of feed microbial fermenting bed was designed. Taking the feed microbial fermenting bed of 200m~2 as an example, the length, width, height and depth of the pigsty were 20m, 10m, 4.5m and 50cm respectively. The management of feed cushion in fermenting bed includes keeping a certain humidity (45%) and ventilating rate (regular tilling), generally raking the surface material of fermenting bed once every 3 days, and the daily turning of pig can also contribute to the looseness of the cushion. The density of feed fermenting bed was 4 piglets per square meter (below 20kg), 2 medium pigs (20~50kg) and 1 large pig (50~100kg). Due to the uneven excretion of pig dung, only a part of pig manure can be dispersed by pig turn-over, and the management of fermenting feed in fermenting bed needs manual treatment, and the concentrated pig manure is distributed evenly in the cushion. The fermenting feed in the fermenting bed pad can provide 30% of the feed needed by the pig, the other 70% of the feed can be supplemented by adding the conventional feed, and the feed can be directly distributed on the fermenting bed for the pig to feed on. The average initial weight of pig was 36.4 kg, the final weight was 59.5 kg, and the feed meat Prida was 2.7: 1. The average initial weight was 36.4 kg and the final weight was 59.5 kg. The incidence was 5g, mainly manifested as fever, depression, low appetite, rehabilitation after treatment or natural rehabilitation. The experience obtained in this experiment provides a basis for further research and popularization of feed fermenting bed.
