Problems solved by technology

However, studies have shown that fatty feed can improve the growth performance of piglets, but the fat structure in breast milk is completely different from the fat structure in the diet, which leads to the inability of the digestive system of piglets to fully digest and absorb, which in turn affects growth performance

Abstract

The invention discloses an application of compound grease comprising freshwater fish oil or the freshwater fish oil after fractionation treatment or combination of the above two types of the grease and other grease in a piglet feed. A dosage of the grease in the feed is 0.5-10%. The other grease is coconut oil and modified deep sea fish oil. The modified deep sea fish oil is obtained by ester exchange of the deep sea fish oil and the coconut oil, especially, on the basis of improvement of grease properties. The invention further relates to a fractionation method for fractionation freshwater fish oil and an ester exchange method, so oil which is better in quality and suitable for piglet growth is obtained. The feed grease is capable of reducing generation of a stress syndrome, and has an apparent function for promoting the piglet growth.

Description

technical field [0001] The invention belongs to the technical field of feed oil, and in particular relates to a preparation method of fat for weaned piglets and its application in piglet feed. Background technique [0002] In order to ensure the productivity of sows and reduce the cost of breeding as much as possible, the piglets will be weaned at an early stage. Early weaning makes the piglets switch from the original liquid sows with complete nutrition and smell to plant-based feeds with completely different aroma, taste and nutritional components. . [0003] In pig production practice, weaning piglet stress syndrome brings great economic losses to pig production. Weaning stress directly leads to a decrease in feed intake of piglets, a sharp decrease in energy for maintenance and growth, and growth stagnation, resulting in a negative balance of energy in the body. Fat has the characteristics of low calorie consumption and high energy, and fatty acids are conducive to the...
