Immune stress prolongs the feeding cycle by 3-5 days on average and increases the cost 10-20 yuan/head.
The pressure of sow production and reproduction: the reproductive ability of sow is low; The newborn weight of piglets is small, the weaning weight is 6-7.5 kg at the age of 25-28 days, the average feeding period is prolonged 10 day, the direct cost is increased 10-50 yuan/head, and the indirect benefit is reduced by 80-200 yuan/head.
Birth elimination: yellow dysentery mainly affects the survival rate of piglets, and the cost increases 10-20 yuan/head;
Feeding custom: white dysentery affects 2-5 days on average, and the cost increases 10-20 yuan/head;
Weaning pass: weaning stress prolongs the feeding period by more than 5 days, and the cost increases 10-20 yuan/head;
Conservation: the feeding cycle of piglets with nutritional stress, chronic ammonia poisoning and respiratory syndrome, low immunity and circovirus infection is prolonged by more than 5 days, which increases the cost 10-20 yuan/head;
Attachment: Diarrhea syndrome of trafficked piglets prolongs the feeding cycle of trafficked piglets by more than 30 days, increasing the cost by 50- 100 yuan/head;
Immunosuppression caused by various factors, especially mycotoxins, reduces the disease resistance of animals and increases the incidence of more than 30 common clinical diseases such as asthma, blue ear disease, circovirus infection, influenza, streptococcus, Haemophilus parasuis and Eperythrozoon. The average feeding period is prolonged by 5- 10 days, and the cost is increased by 10-30 yuan per head.
Improper passive health care will prolong the feeding period by 5- 10 days.
From the above analysis, it can be seen that theoretically, if the above constraints can be solved, the feeding cycle can be shortened by 35-50 days, and the income of each pig can be increased by 40- 1 100 yuan, which is the theoretical basis of 135 healthy pig raising. The so-called 135 high-efficiency health-care pig-raising technology was put forward by experts such as Wen Lixin and Hui Yuan in theory. Using modern biotechnology and active health care methods of nutrition and immune regulation can improve its production performance and greatly reduce and control common diseases and frequently-occurring diseases. At present, the average time for slaughtering pigs can be shortened to 135 days, and the meat quality has been improved. It is estimated that each pig can increase its income by 40- 100 yuan.
Health pig raising is the future development trend, and the development of health medicine and health technology is setting off a technological revolution in aquaculture. Since 2002, Changsha Lvye Biotechnology (Group) Co., Ltd. has organized a group of famous experts and professors in China to carry out research on this, and has taken the lead in putting forward the basic concept and technical principle of healthy pig raising at home and abroad, and carried out a series of scientific research, which has been recognized and welcomed by industry professionals and pig raising friends.
