Problems solved by technology

For this reason, European and American countries have developed a variety of milk powder products for piglets, but the fatty acid composition in these product formulas is very different from the measured value of the fatty acid composition of pig milk, which affects the feeding effect of milk powder for piglets

example 1

[0051] Example 1: Preparation of a swine milk fat replacement fat composition using sardine oil, corn oil, and palm oil as base oils. The optimal ratio that satisfies the conditions of swine milk fat composition is obtained as sardine oil: corn oil: palm oil=30.78%: 54.56%: 14.66%, and the similarity score of its fatty acid composition and swine milk fatty acid composition is 93.48 points.

example 2

[0052] Example 2: Preparation of a swine butterfat replacement fat composition using sea bass oil, palm oil and cottonseed oil as base oils. The optimal ratio that satisfies the conditions of swine milk fat composition is obtained as perch oil: palm oil: cottonseed oil=38.85%: 16.84%: 44.31%, and the similarity score of its fatty acid composition and swine milk fatty acid composition is 84.49 points.

example 3

[0053] Example 3: Preparation of a swine butterfat replacement fat composition with salmon oil, sunflower oil, palm oil, soybean oil as base oils. The optimal ratio that satisfies the conditions of swine milk fat composition is obtained as salmon oil: sunflower oil: palm oil: soybean oil = 30.08%: 23.87%: 30.88%: 15.18%, and the similarity score between its fatty acid composition and swine milk fatty acid composition 95.33 points.

Abstract

The invention relates to a pig milk substitute fat composition by simulating pig milk fatty acid compositions. The pig milk substitute fat composition is formulated from a variety of base oils, including fish oil, linoleic acid type vegetable oil and palm oil. According to the invention, the pig milk substitute fat composition is proportioned in percentages by mass: 10%-40% of fish oil, 10%-55% of linoleic acid type vegetable oil and 10%-60% of palm oil, wherein the fish oil contains 4% of palmitoleic acid or above, the linoleic acid type vegetable oil contains 50% of linoleic acid or above, and the linoleic acid type vegetable oil contains 50% of linoleic acid or above. The similarity score of the pig milk substitute fat composition to pig milk is 80% or above (totally 100 points, the same below), and the pig milk substitute fat composition can remarkably increase the survival rate and the weaning weight of piglets in China, with great economic significance and social benefits.

Description

technical field [0001] The invention relates to the fields of animal nutrition and feed science in animal husbandry, in particular to a swine milk substitute fat composition simulating the fatty acid composition of swine milk. Background technique [0002] my country's live pig production accounts for more than half of the world's total. The number of piglets born each year is 800 to 900 million, and the survival rate is about 80%, while the survival rate of piglets in developed countries such as Denmark and the Netherlands can be as high as 90%. above. Based on this calculation, my country loses about 100 million piglets every year, and the direct economic loss is as high as 15 billion to 40 billion yuan. In addition, according to the calculation of my country's animal husbandry industry, if the weight of piglets is 0.5kg lighter at weaning, the piglets will be 5kg lighter when they are released, and the loss will further increase. Pig milk is the most ideal food for pigle...
