Management requirements of pig feeding system

With the progress of the times and the continuous development of science and technology, pig breeding equipment has been widely used in pig farms. At the same time, the all in and all out system has emerged. Here is the introduction of the management requirements of the all in and all out system.
1. Sanitation standard: before delivery of different batches of sows, the delivery house and equipment shall be thoroughly cleaned and disinfected. Cleanliness and sterility are the key to the success of delivery management. The pigsty that has not been emptied cannot be cleaned and disinfected thoroughly. Only when every pig house is emptied and thoroughly cleaned and disinfected can the full in and full out system be effective. The traditional continuous feeding system is impossible to do so, otherwise it will interfere with production.
2. Environmental stability: the all in and all out system makes it easy for producers to provide a stable environment for each batch of pigs of the same age. If the environmental conditions of one or more delivery houses are most suitable for newborn piglets, the environmental conditions of the other one or more delivery houses will be suitable for larger suckling piglets. Traditional feeding system, environmental conditions can not meet the needs of pigs of different ages.
3. Reduce the spread of disease: the all in and all out system enables producers to avoid the mixing of pigs of different ages. When pigs of different ages are fed separately, the chance of cross infection and exposure to pathogens will be reduced. The main reason is that there are different pathogens in different pig groups, and the whole in and out system will reduce the chance of pig groups exposed to pathogens.
Through cooperation with Zhengda Group and other large pig farm groups, Pratt & Whitney has accumulated a lot of practical experience, and its products have also withstood the test of the market. If there is a need for farmers and friends, please call us!
