Technical Problem

Traditional farrowing pens have fixed spaces that cannot accommodate the needs of sows of different sizes. This leads to stress in large sows and makes it inconvenient for small sows to care for their piglets. Furthermore, frequent replacement of pen components disrupts the stable living environment for both sows and piglets.

Method used

An adjustable farrowing fence was designed. The adjusting mechanism moves the separating mechanism, which can flexibly adjust the size of the activity area for breeding pigs and piglets. The height of the horizontal bar can be adjusted to prevent sows from entering the piglet area, thus providing safety.

Benefits of technology

It enables flexible adjustment of activity space according to the sow's body size, avoids stress response, improves piglet survival rate, simplifies the adjustment process, saves manpower and material resources, and maintains a stable living environment for sows and piglets.

Abstract

The utility model discloses an adjustable local boar limiting delivery fence which comprises a base, four sets of stand columns are fixed to the top of the base, and a fence is fixed between every two adjacent stand columns. Compared with the prior art, the adjusting mechanism is arranged to drive the separation mechanism installed on the side face of the shell to move, the space size of a boar and piglet activity area can be flexibly adjusted according to the body types of sows through the design, and the problems that a traditional delivery fence is fixed in space and cannot adapt to the sows of different body types are solved; stress reaction of large-size sows due to narrow space is avoided, small-size sows can conveniently take care of piglets, safety guarantee is provided for the piglets through the design of the separation mechanisms, the sows can be effectively prevented from entering the piglet activity area and being prevented from crushing the piglets during sow delivery and daily activities by adjusting the height of the transverse rod, and the sow delivery efficiency is improved. The survival rate of the piglets is improved.
