A kind of lactating sow reproduction promoting fatty acid triester composition

Abstract

The invention provides a fatty acid triester composition for promoting propagation of lactation sows. The weight percentage of fatty acid triester in the fatty acid triester composition is 30-60%, the percentage by weight of encrusting substances or carriers is 40-70%, fatty acid in the fatty acid triester comprises medium and short chain fatty acid and long chain fatty acid, the long chain fatty acid comprises monounsaturated fatty acid, omega-3 fatty acid, omega-6 fatty acid, linoleic acid and linolenic acid, the mass ratio of the medium and short chain fatty acid to the long chain fatty acid is (0.05-0.15) to 1, the mass ratio of the monounsaturated fatty acid to the omega-3 fatty acid to the omega-6 fatty acid is (2-3.5) to 1 to (2-5), and the mass ratio of the linoleic acid to the linolenic acid is (6-15) to 1. The fatty acid triester composition disclosed by the invention is used for promoting the propagation performance of the lactation sows.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a reproductive-promoting fatty acid triester composition for lactating sows. Background technique [0002] Fat is the most important and effective energy source, adding fat to feed can provide higher energy concentration with less formula space. The purpose of using fats and oils in the feed industry is to cost-effectively increase the energy level of feed. However, with the in-depth research on fat nutrition by nutrition experts, it is found that functional fatty acid esters play a very important role in animal reproductive performance. [0003] CN104824377A discloses a heat stress-resistant and reproductive-promoting composite additive for sows, which includes the following components: tea polyphenols, betaine, NCG, Vc, VE, Naikeshu, biotin and folic acid. It uses components with different functions in combination to improve the effect of heat stress resistance of so...

Problems solved by technology

[0005] In the above prior art, the feed additives that promote the reproduction of sows are mainly composed of multiple vitamins, such as vitamin A, vitamin C, vitamin D, and vitamin E. However, vitamins are used as feed ingredients, although they can improve the stress resistance of sows ability, but there are the following problems: 1. It is difficult to ensure sufficient lactation and high-quality milk for sows, resulting in increased piglet mortality; 2. Sows lose a lot of weight and poor body condition during lactation; 3. It is difficult to improve ovulation of sows 4. Prolonged estrus and mating time or no estrus, high elimination rate

[0007] The effect of adding fat to sow rations has been confirmed by domestic and foreign experts, however, adding fat to lactation feed rarely achieves the desired effect

The main problems are: (1) Many current studies are limited to a single oil or a simple combination of several oils in different proportions, without fully considering the U / S ratio, ω-6 / ω-3 ratio, and short- and medium-chain fatty acids in the feed. and the ratio of long-chain fatty acids, resulting in unbalanced composition of fatty acids in the feed of lactating sows, and fatty acids with unbalanced composition are easy to accumulate in the subcutaneous and abdomen, affecting the milk production performance of sows; (2) complex oil use, unstable quality, hinder Fatty acid metabolism, affecting the health status of sows

(3) Oils and fats commonly used in feed: soybean oil, phospholipid oil, lard oil, and palm oil have zero n-3 fatty acids, medium and short-chain fatty acids, and lecithin, which lead to a lack of functional fatty acids in feed, which in turn affects the growth of sow follicles Development and maturation, hampers reproductive performance of sows
