Description

An antibiotic-free artificial milk and liquid diet for suckling pigs

technical field

The invention belongs to the technical field of feed, in particular to artificial milk and liquid diet for suckling pigs without antibiotics.

Background technique

Sow breeders often encounter situations such as too many litters of sows, death of sows after delivery, habit of biting (eating) piglets, anemia or insufficient lactation of sows after delivery, and serious diseases of sows after delivery that are not suitable for breastfeeding. It is necessary to prepare artificial milk to raise these "orphan pigs", otherwise the "orphan pigs" may starve to death or cause growth and development disorders, resulting in unnecessary economic losses. In order to promote ultra-early weaning (7 days old), some pig farms need to prepare artificial milk to feed piglets to make them grow normally and improve the survival rate and breeding rate. Artificial milk is mostly made of skimmed milk, buttermilk and vegetable feed, plus animal fat, carbohydrates, vitamins, inorganic salts, antibiotics and other ingredients necessary for the normal growth and development of piglets. The level of disease resistance of newborn piglets directly affects the survival rate, breeding rate and growth rate of piglets. If the artificial milk preparation is unreasonable, it will lead to growth retardation, decreased feed intake, diarrhea and other problems in piglets. At present, sub-therapeutic doses of antibiotic growth promoters are usually added to feed to ensure the normal growth of piglets and resistance to pathogenic microorganisms. However, many negative problems caused by the use of antibiotics have attracted worldwide attention, such as inducing the emergence of multidrug-resistant strains and so on.

Contents of the invention

The technical problem to be solved by the present invention is to provide a sucking pig artificial milk without antibiotics, which can effectively replace breast milk without antibiotics and can effectively replace breast milk, and can improve postpartum agalactia or insufficient lactation of sows. The growth of piglets is hindered due to severe epidemic diseases after pigs are not suitable for breastfeeding.

The nutritional level of the artificial milk formula for suckling pigs without antibiotics in the present invention fully considers the nutritional needs of piglets, and the rational collocation of various raw materials is carried out. And refer to the 2004 version of the Chinese pig feeding standard and the 2012 version of the American pig nutritional requirements for the nutritional needs of 3-8kg piglets. Crude protein: 24%, digestible energy: 19.5MJ/kg, crude fat: 12%, calcium: 1.34%, available phosphorus: 0.73%, lysine: 2.25% in artificial milk formula obtained through the most optimal formula , Methionine + cystine: 0.98%, can fully meet the nutritional needs of suckling piglets.

Among the components of the suckling pig artificial milk:

Whole milk powder: It is produced with pure cow's milk, contains high-quality protein, fat, multivitamins, calcium, phosphorus, iron and other minerals in milk, basically maintains the original nutrients in milk, and the protein is not less than 24 %, fat not less than 20%, lactose not less than 37%. Comprehensive nutrition, good palatability and high digestibility can ensure the healthy growth of piglets.

Whey protein concentrate: Whey protein concentrate is a powder produced by spray-drying bovine whey, which contains protein, various essential amino acids, lactose, mineral elements and a small amount of fat, and is rich in various vitamins and a high proportion of immune cells Protein, protinin, such as lysozyme, lactoferrin, growth factors, nucleotides, hormones, cytokines, etc., the protein content is 34% to 80%, with good palatability and digestibility, more than any other protein Easy to digest. At the same time, whey protein concentrate has the functions of anti-virus and improving the immune function of the body. Very suitable for application in suckling pig feed.

Whey powder: Whey powder is made by drying whey, a by-product of making cheese or casein. It generally contains 65% to 75% lactose and about 12% crude protein. Whey powder can provide a large amount of lactose, which can produce a large amount of lactic acid when fermented in the digestive tract of piglets, lowers the pH value, helps the digestion of milk, and inhibits the growth of pathogenic bacteria. , which is of great significance to the health of piglets; the high-quality whey protein contained in whey powder has the advantages of high digestibility, good amino acid profile, and no anti-nutritional factors in piglets, and is suitable for sucking pigs.

Fishmeal: Fishmeal is a high-quality animal protein raw material, which is rich and balanced in amino acids, calcium, phosphorus and trace elements. Many studies have reported that fishmeal contains unknown growth-promoting factors, and its exact components have not been purified, so it has not been named, but its growth-promoting effect is recognized and affirmative.

Coconut oil: Coconut oil contains a high proportion of medium-chain fatty acids. Medium-chain fat molecules are smaller than other long-chain fat molecules and are easily digested and absorbed. Medium-chain fatty acids have natural comprehensive antibacterial capabilities. When ingesting medium-chain triglycerides, It is converted in the body to monoglycerides and medium-chain fatty acids, which have powerful antibacterial properties that kill disease-causing bacteria, fungi, viruses and parasites. It can prevent piglets from being infected with E. coli.

Lysine hydrochloride: It is an essential amino acid and the first limiting amino acid for pigs. The lack of lysine in the feed seriously affects the growth performance, carcass quality, immune function, serological parameters, and nutrient digestibility of piglets.

Arginine hydrochloride: It has been reported that adding arginine to the diet of young piglets can significantly improve the intestinal barrier function of piglets and improve production performance. Other studies have also shown that arginine can significantly improve intestinal morphology in piglets.

The main component of the beneficial long element is soybean isoflavone. Adding soybean isoflavones can maintain the integrity of duodenal mucosa of piglets, significantly increase the height of villi and reduce the depth of crypts. Improve the antioxidant function and immune function of intestinal mucosal cells.

The second technical problem of the present invention is achieved through the following technical scheme: a liquid ration for suckling pigs without antibiotics, comprising the above-mentioned artificial milk for suckling pigs, liquid choline chloride, lactobacillus and water.
