Liquid condition feedstuff and preparation method thereof

Abstract

The invention relates to a liquid forage and the preparation method, which comprises the following components in weight percentage: corn 20 to 60 percent, puffing soybean 15 to 50 percent, whey powder 2 to 15 percent, blood plasma protein 1 to 10 percent, fish meal 2 to 15 percent, treacle 1 to 7 percent, soybean oil 1 to 5 percent , CaHPO4 0.1 to 2 percent, stone powder 0.1 to 1 percent, NaCl 0.1 to 2 percent, choline 0.1 to 1 percent, L-Lys (L- lysine salt) 0.1 to 1 percent, DL-Met (methionine) 0.1 to 1 percent, pre-mixture 1.00 to 4.00 percent, and deflocculant 0.1 to 2 percent. Compared with the dry forage, the invention enhances the food intake of weaned newborn pigs; the invention also increases the feeding speed; the liquid forage can avoid the damages of dry forage to the intestinal wall morphology of weaned newborn pigs; liquid forage is beneficial to the inner environment of the digestive canal of newborn pigs; the enhancement of growing performance of early weaning newborn pigs can also be gained from the increase of ADFI, and simultaneously low pH value is also helpful to the protein digestion in the stomach of newborn pigs. The invention has the advantages of the regulation of the growing performance, the influence on the immunity function, and the balance of intestinal microbiological flora of early isolated weaning newborn pigs to reduce the cultivation cost greatly.

Description

Technical field [0001] The invention relates to a feed, in particular to a liquid feed. At the same time, the invention also relates to a preparation method of the liquid feed. Background technique [0002] Liquid feed refers to a fluid mixture of water and feed through a certain processing technology or a mixture of liquid by-products after food processing and conventional feed materials. The typical liquid feed contains 20-30% of dry matter. The piglets are fed milk and the pigs are fed with swill in rural areas are typical examples. In the rural areas of our country, many farmers use the powder to soak in hot soup, then add other raw materials, and then mix it into a porridge or paste, and then feed the piglets. Such examples are more common in Guangxi and Sichuan, China. [0003] The liquid feeding method of traditional family pig raising cannot meet the requirements of large-scale intensive pig raising. With the in-depth study of liquid feeding and the development of compute...

AI Technical Summary

Problems solved by technology

However, there are also the following problems in the application: (1) nutritional and metabolic stress of early weaned piglets; (2) strict isolation conditions and hygienic requirements; (3) formula and processing quality requirements of SEW piglets; (4) low Weaning at the age of 14 days may have an impact on the reproduction of sows; (5) Feeding management equipment requirements

[0011] In the 1950s, British scholars created the SPF technology, using cesarean section or aseptic inoculation technology to obtain piglets before the sows were about to give birth, and transferred the piglets to an isolated breeding piglet house under aseptic conditions, until the piglets were able to give birth. The first generation of SPF pigs (Yang Gongshe, 2002), but due to the high cost of SPF pigs, high technical difficulty and special requirements for feeding and management, it is difficult for SPF pig herd technology to be generally applicable to the needs of the modern pig industry

[0015] (2) Insufficient secretion of digestive enzymes and gastric acid

[0017] (3) Insufficient immune system function

[0019] (4) Disappearance of maternal beneficial factors

Some plant proteins can also cause allergic reactions in piglets, damage the intestinal mucosa of piglets, shorten villi, deepen crypts, reduce digestion and absorption functions, and eventually cause diarrhea

[0023] (6) The microflora of the gastrointestinal tract is variable

This series of changes resulted in insufficient feed intake of piglets, which limited the maximum growth performance of piglets
