Device for letting live pigs out of pigsty in large-scale pig farm

Abstract

The invention relates to a device for letting live pigs out of a pigsty in a large-scale pig farm. The device comprises a pigsty out-letting house, a weighbridge and a boarding ramp. The device is characterized in that the weighbridge is installed on the terrace of the pigsty out-letting house, two doors and fences which form an enclosure are arranged around the pigsty out-letting house, the distance between the bottom edge of the internal side of each fence and the edge of the weighbridge is no more than 4cm, one door is a weighbridge entry door and is communicated with the pigsty out-letting house and a pigsty, the other door is a weighbridge exit door and is communicated with the pigsty out-letting house and the boarding ramp, the boarding ramp rises gradually, the inclination of the boarding ramp is less than or equal to 30 degrees, the highest position of the boarding ramp and the bottom of a rear carriage of a live pig transport vehicle are at the same level, the boarding ramp consists of a ramp groove and a support and the height of the support is adjustable. The live pigs can be tempted by foods and the like to actively get out of the pigsty, the howls of the live pigs when the live pigs get out of the pigsty are reduced, the stress response of the live pigs which get out of the pigsty and the live pigs which stay in the pigsty is minimized, the disease infection which is possibly caused when the transport vehicle gets in and out of the pig farm is positively prevented and the cost of letting the live pigs out of the pigsty is obviously reduced.

Description

1. Technical field [0001] The invention relates to animal husbandry and pig raising, and mainly relates to a device for slaughtering pigs in large-scale pig farms. 2. Background technology [0002] In recent years, large-scale pig breeding has developed rapidly. Large-scale pig farming can produce 500 to 5,000 pigs a year. The traditional method of slaughtering pigs mainly uses manpower to grasp, bundle, weigh, and lift. Pigs instinctively struggle in an emergency and howl loudly. Due to the relatively concentrated slaughter of live pigs in large-scale pig farms, the stress response of slaughtered pigs and stocked pigs is obvious, and the production of pig farms is greatly affected. This undoubtedly increases the cost of breeding and causes large economic losses to the pig farm. In order to effectively solve the problem of mass slaughtering of pigs in large-scale pig farms, a device that basically maintains the normal state of live pigs, effectively controls the howling nois...
