Premix for improving fat digestion, absorption and growth performance of weaned pigs

Abstract

The invention discloses a premix for improving fat digestion, absorption and growth performance of weaned pigs. The premix comprises the following components in parts by weight: 60 to 75 percent of protein substances, 1 to 2 percent of a compound enzyme, 0.3 to 1 percent of composite mineral substances, 0.3 to 1 percent of compound vitamin, 2 to 7.5 percent of inorganic composition, 7 to 10 percent of cane sugar, 0.3 to 1 percent of tributyrin, 0.5 to 1 percent of formic acid, 0.8 to 1.3 percent of antioxidant, 1500 to 2000 mg / kg of choline or / and 2000 to 3000 mg / kg of bile acid, 5 to 7 percent of yeast extract and 6 to 9 percent of wheat middling. The premix provided by the invention is mixed with corn-soybean meal in a ratio of 10%-30% for use, can significantly improve the fat digestionand absorption of weaned piglets, improve the growth performance, save energy raw materials and improve the energy utilization rate, and is simple to prepare and suitable for large-scale use.

Description

technical field [0001] The invention relates to the technical field of feed premix, in particular to a premix for improving fat digestion and absorption and growth performance of weaned piglets. Background technique [0002] The body fat content of newborn and weaned piglets is extremely low, less than 2% of body weight, and the body's energy reserves are limited, which is not conducive to the survival of piglets. If the energy intake of piglets from the diet is not enough for growth and development, it can cause slow or stagnant growth of piglets. In animal husbandry, high-energy diets are often used to feed weaned piglets to improve piglet growth performance. Among them, the conventional method to increase dietary energy is to add oil. The part of fat digestion is mainly in the small intestine, and it is decomposed under the action of lipase, etc., and the products are mainly fatty acids and glycerol, among which long-chain fatty acids are esterified into triglycerides, ...

Problems solved by technology

[0004] The decoction of traditional Chinese medicine composed of yam, licorice, purslane and malt can promote fat absorption and improve the anti-stress ability of piglets. It is used in large quantities in large-scale farms; patent application CN 201610283728.9 discloses a teaching trough feed that uses ideal fat raw materials to improve the production performance of suckling piglets. High-pressure saturated steam is introduced into the emulsification tank for steam conditioning (temperature is 60-65°C ) to emulsify fats and oils, but this operation process is difficult for most farms to realize under the existing process; patent application CN 201810747819.2 indicates that using bile acids as feed additives can improve the growth performance and feed utilization of weaned piglets, and improve fat digestion rate, but no further research elucidated

Currently, the inventions disclosed for improving fat digestion and absorption and growth performance of piglets are either limited by the cost or limited by the process, and have not been applied on a large scale in production. There is no technical solution with low cost and simple process to solve the above problems. question
