Key technique for scientific healthy farming of pigs

Abstract

The invention provides a key technique for scientific healthy farming of pigs. The key technique includes a sow mating technique, a sow pregnancy management technique and a production sow and neonatal piglet feeding and management technique. Through the fine management and health caring for sow mating and pregnancy and the production and neonatal piglets, pregnancy rate is above 95% for sows, barren rate is greatly reduced, service life of each sow is prolonged, attack rate of reproductive system diseases is greatly reduced, the delivery rate is accurate, the farrowing rate is high, live farrowing rate is above 98%, the average bearing rate of each sow is 12 to 14 piglets, the sows are of high milking capacity in the post-farrowing suckling phase, milk quality is high, milking peak period can be prolonged, the neonatal piglets are of uniform physique, healthy and high in disease resistance, weaning weight of the piglets after weaning at the age of 24 days is above 7kg, farm cultivation cost can be reduced, the economic benefit can be increased, and the key technique has promising application prospect.

Description

technical field [0001] The invention belongs to the technical field of farming. More specifically, it relates to a key technology for scientific and healthy pig raising. Background technique [0002] Since the reproductive performance of sows plays a decisive role in the benefits of pig farms, and the reproduction of sows requires meticulous management from breeding, pregnancy, production, lactation to re-breeding, improper handling of any link will cause damage to the pig farm. Sow breeding has adverse effects. For example, many pig farms have misunderstandings in the feeding of sows, and the feed supply is relatively simple. Because the nutrition required by sows at each stage needs to be adjusted according to actual physical needs, such as the main purpose of lactation It is to prevent the sows from losing too much weight as much as possible, improve the lactation ability of the sows and prepare for the estrus mating as soon as possible after weaning. Therefore, the prop...

[0002] Since the reproductive performance of sows plays a decisive role in the benefits of pig farms, and the reproduction of sows requires meticulous management from breeding, pregnancy, production, lactation to re-breeding, improper handling of any link will cause damage to the pig farm. Sow breeding has adverse effects. For example, many pig farms have misunderstandings in the feeding of sows, and the feed supply is relatively simple. Because the nutrition required by sows at each stage needs to be adjusted according to actual physical needs, such as the main purpose of lactation It is to prevent the sows from losing too much weight as much as possible, improve the lactation ability of the sows and prepare for the estrus mating as soon as possible after weaning. Therefore, the proportion of protein feed needs to be increased in terms of nutritional requirements, and unreasonable nutritional feeding will cause As a result, the sows are not well absorbed, and it is easy to cause insufficient feeding, which affects the growth and breeding of the entire stage in the later stage; another example is that the pregnancy stage needs to be adjusted in time according to the sow's physique and embryonic development rules. Nursing also needs to be refined to improve its production rate and growth and breeding capacity. At present, there is no complete set of technical means to fully meet the needs of the above-mentioned stages. Therefore, a key technology is urgently needed to adapt to sows and sows. Growth and breeding requirements of piglets at each stage
