Method for producing sows in large scale and in batch

Abstract

The invention relates to a method for producing sows in large scale and in batch and belongs to the field of sow production. The batch production method for producing the sows in large scale and in batch is another production mode relative to week production. By adjusting the oestrous period of the sows, the sows are in oestrus and mate through centralization, ablactation is conducted simultaneously in the same day, and the sows are transferred for care. After batch production is implemented, the difference of day ages of the sows in the same batch is small, the difference of the sows of day ages in different batches is large, all the batches are clear, and breeding management and disease prevention and control are facilitated. Through batch production, the stable health of sow herds is kept to a great extent, the daily weight gain can be increased, and the death rate can be lowered. Through a batch production technology, the death and culling rate can be obviously lowered, the marketing daily age of big fattening sows is advanced, and thus the death and culling cost and the fodder cost are lowered. In a word, the method for producing the sows in large scale and in batch is reasonable in design and easy to operate, the labor intensity of workers is lowered, centralized management is facilitated, and the method is suitable for application and popularization.

Description

technical field [0001] The invention relates to a batch production method for large-scale sows, belonging to the technical field of sow production. Background technique [0002] In recent years, it has become more and more difficult to prevent and control diseases in China's pig industry. It is difficult to achieve the expected results through simple veterinary prevention and control methods. However, the traditional random production method of sows has low production efficiency of pigs, and diseases are not easy to control. It is not conducive to centralized and unified management. [0003] Compared with the weekly production mode, the batch production technology has been developed, which can effectively help existing pig farms to improve pig production efficiency. The batch production process is a new production process compared to the traditional continuous production mode. It concentrates and regularly completes the production operations such as breeding, parturition, w...
