现代化养猪场设计方案
——年出栏1000头商品猪
摘要我国具有悠久的养猪历史,有发展养猪业的丰富资源,包括猪的品种资源、饲料资源和农村养猪的传统,但是在养猪技术方面比较落后,存在着劳动生产率低、商品率低等问题。近年,随着农村专业户数量逐年增加,养猪业科学技术日益普及,专业养猪业也逐步巩固和繁荣。作者结合所学专业及其参观养猪场的感受,就以年出栏1000 头肥猪为例,拟定设计一个现代化养猪场建设方案。根据机械化养猪饲养工艺,就猪场的功能和生产建筑、辅助建筑和猪场机械化等规划设计作初步探讨。

Abstract China has a long history of pigs, development of the rich resources of both the industry, including the pig variety resources, feed resources and rural pig tradition, but on pigs technology is relatively backward, there are low labor productivity, low quality problem. In recent years, along with the rural raiser the number increases year by year, both the industry science and technology increasing popularity, professional pig industry is also gradually consolidating and prosperity. Based on field and visit the feeling of the pig farm, in a year 1000 head of pig such as an example, draws up the design a modern farm construction plan.

1 规划设计依据
一个年产1 000 头肥猪的养猪场,需要饲养存栏公猪2头,生产母猪83头,哺乳期仔猪100头,保育猪1000头,生产育成猪
370头。机械化养猪的规划设计主要依据饲养工艺,目前普遍采用以周为节拍的全进全出的饲养工艺[1],该设计采用早期断奶(10 ~ 20日龄)隔离饲养:
工艺特点:早期断奶(10 ~ 20 日龄),隔离饲养是养猪新工艺,简称SEW(segregated early weaning)。早期隔离断奶即根据猪群本身需清除的疾病,在10 ~ 20 日龄内进行断奶,然后将仔猪送到距离分娩舍250 m 以外的清净区保育舍隔离饲养,这就是早期断奶(10 ~ 20 日龄)二点式隔离饲养。新发展的SEW 饲养工艺具有增加母猪产仔胎数,切断仔猪被母猪或其他大猪传
