Large scale farming feed for piglets and feeding method thereof

Abstract

The invention relates to a large scale farming feed for piglets and a feeding method thereof. The feeding method comprises feeding milk replacer at a lactation stage, feeding at the earlier stage of nursing, and feeding at the later stage of nursing, wherein the milk replacer at a lactation stage is prepared from corns, bean pulp, extruded soybeans, whey powder, imported fish meal, phospholipids powder, whole milk powder, glucose, cane sugar, calcium hydrophosphate, threonine, zinc oxide, threonine, methionine, choline chloride, an acidifier, and 1% piglet core material; the feed for the earlier stage of nursing is prepared from corns, bean pulp, extruded soybean, whey powder, soybean oil, calcium hydrophosphate, mountain flour, cane sugar, lysine, threonine, methionine, choline chloride, an acidifier, a complex enzyme, phytase, a sweetening agent, montmorillonite, salt and 1% piglet premix; and the feed for the later stage of nursing is prepared from corns, bean pulp, extruded soybeans, soybean oil, calcium hydrophosphate, mountain flour, cane sugar, lysine, choline chloride, an acidifier, a complex enzyme, phytase, a flavoring agent, salt and 1% piglet premix.

Description

technical field [0001] The invention belongs to the technical field of suckling pig breeding, and in particular relates to a feed for large-scale breeding of suckling pigs and a feeding method thereof. Background technique [0002] With the rapid development of large-scale, intensified and industrialized pig farming in my country, in order to increase the reproductive rate of sows and improve the economic benefits of pig farming, many pig farms have adopted the early weaning technology of suckling pigs, that is, 21-28 days after the birth of piglets. However, due to the special digestive physiological characteristics of piglets, early weaning often causes diarrhea and other secondary diseases in piglets. The survival rate is low, which seriously affects the growth and development of piglets, and has become a bottleneck restricting the development of the pig industry. [0003] Diarrhea in suckling piglets is a common problem in current pig farms, and it is also one of the most...

AI Technical Summary

Problems solved by technology

[0004] 1. In order to quickly improve economic benefits and increase the reproductive rate of sows, some pig farms blindly pursue the early weaning age. , the piglets did not eat the feed at all, and they were weaned at the time (21-28 days old); especially when the sows were lactating well, the piglets generally would not eat feed after eating enough breast milk, and there was no food inducement. Piglets with trough feed are prone to diarrhea after weaning because the gastrointestinal digestive enzyme system has not established the function of digesting feed;

[0005] 2. Although some pig farms use early feeding at the age of 7 days, it is only a formality and has no actual effect. Generally, the feeding trough is placed outside the incubator (because the piglets are afraid that they will not go out to eat), or they do not control the feeding time of the piglets ( The sow has good milk, and the piglets that have had enough breast milk do not eat the feed), or pour the feed into the feeding trough, and the suckling pigs do not know whether to eat or not, some eat and some do not eat, in fact, early induction However, after weaning, the sows are separated. Since there is no breast milk for a long time, the suckling pigs that did not eat the creep feed before weaning often cause excessive hunger and overeating feed, resulting in gastrointestinal dysfunction. adaptation, leading to indigestion and diarrhea;

[0006] 3. After weaning, due to the lack of food troughs, the piglets compete with each other for food. The strong eat more, and the weak eat less.

[0007] 4. The function of regulating body temperature of newborn piglets is not perfect, and their resistance to cold is poor. If good heat preservation measures are not taken after weaning, it will lead to environmental stress, and piglets are prone to cold and diarrhea;

[0008] 5. Piglets have fast growth and development, strong metabolic function, and strong ability to utilize nutrients, but their needs for nutrients are high in both quantity and quality, and they are particularly sensitive to nutrient-deficient feed.

Therefore, after the piglets are weaned, in a short period of time, the piglets have not fully adapted to the creep feed, so the nursery feed is replaced. There is no transition period when the feed is changed. In addition, the selected feed is not suitable for the digestion and absorption function and nutritional needs of the piglets. , it is easy to cause feeding stress in piglets, or poor quality feed, poor palatability or too much food attractant, piglets do not eat or overeat; or insufficient or excess protein in feed, lack of amino acids, too much antibiotics, there are effects Growth factors, etc., are likely to cause damage and atrophy of the small intestinal villi of piglets, damage the digestive enzyme system, and cause indigestion and diarrhea

[0009] In addition, in the past, one-time ripening and granulation was adopted in the production and processing of suckling piglet feed. Due to the high temperature granulation of such products, many nutrients such as amino acids, vitamins, trace elements and biological agents are easily destroyed, resulting in feed products. Insufficient nutritional value also seriously affects the growth and development of piglets
