The 12th Liman China Pig Conference opened on October 20, 2023. Adhering to the concept of "providing science-based solutions for the world pig industry - and continuously sharing cutting-edge scientific research results from authoritative experts around the world, Liman has invited more than 100 authoritative experts and scholars, senior practitioners and well-known entrepreneurs at home and abroad." Representatives from Vietnam, Indonesia and other international participants will also gather in Xi 'an.
Dr. Wang Haifeng, from Lihua Shares, shared the content of "Using the characteristics of buildings, reasonable layout of pig production in the Group".
Research background: The existing layout of Lihua building pig farming and the advantages and disadvantages of building pig farming, Dr. Wang used big data analysis, the preliminary conclusion is that building farming all-in all-out growth rate is fast, the material has certain advantages compared with flat farming.
Results: Dr. Wang's team did 36 days of batch buildings, although the productivity was reduced by 7%, but the building was stratified to do batch production, which was convenient and more powerful to reduce the loss of blue ear.
The reason is that there is only one batch in the whole delivery room, all in and all out; Conserve 2 batches, 2 layers for the same batch of pigs; Fattening 3 batches, half for the same batch of pigs; The 36-day batch has lower requirements than the 28-day batch, but the production capacity is wasted by 6%. After building experience, we built another two-point building field in Hefei, raised 20,000 for conservation and 20,000 for fattening, and the clinical results showed a high survival rate.
There are two main reasons: (1) The integrated blue ear positive stable field, independent people and houses to raise double Yin fat pigs, can also maintain double Yin; (2) The airflow control of the building has a certain blocking effect on the air transmission of the blue ear.
Building single fattening farm, the middle policy is to receive blue ear negative seedlings, blue ear induced chain balls, auxiliary pigs, etc. the lowest loss and first blue ear negative weaning seedlings, and then into blue ear positive stable farm pigs.
