Problems solved by technology

[0003] However, since the polyunsaturated fatty acids contained in oil are easily oxidized during storage and transportation, a variety of toxic primary and secondary oxidation products are produced, which will deteriorate the oil and taste, and reduce the nutritional value of feed
Oxidation products of oils and fats can combine with proteins, nucleic acids, lipids and other biomacromolecules in animals, destroying their biological activity, disrupting the redox state of the body, affecting reproductive performance, reducing animal production performance, and affecting animal product quality

Embodiment 1

[0018] A feed additive for relieving liver oxidative damage of piglets caused by oxidized oil in the diet of lactating sows, used in the diet of sows from 107 days of gestation to weaning of piglets.

[0019] 1. Composition of the experimental diet

[0020] The basic diet for sows refers to the nutritional requirements of late-pregnancy sows and lactating sows in the United States (2012), the pig feeding standards issued by the Ministry of Agriculture of China in 2004, and the "Chinese Feed Composition and Nutritional Value Table (2020 31st Edition)" Prepare. The composition and main nutritional levels of each diet are shown in Table 1. Experimental group 1 and experimental group 2 used oxidized soybean oil instead of fresh soybean oil in the control group. At the same time, the experimental group 2 added 0.04% of the feed additive of the present invention instead of corn on the basis of the experimental group 1 diet.

Abstract

The invention provides a feed additive for relieving oxidative damage to the liver of a piglet caused by oxidized grease in a lactating sow feed. The feed additive comprises the following components in percentage by weight: 85% of resveratrol, 10% of DL-alpha-tocopheryl acetate, 1% of saccharin sodium salt, 1% of citric acid, 2% of L-carnitine and 1% of zeolite powder. The feed additive is used in a feed for sows from the 107 day of pregnancy of the sows to the weaning period of piglets, the addition amount of the feed additive is 0.04%, and the feed additive can enhance the antioxidant enzyme activity of the livers of suckling piglets and meanwhile can reduce accumulation of oxidation products in liver tissue.

Description

technical field [0001] The invention belongs to the application field of agriculture and animal husbandry, and in particular relates to a feed additive for alleviating liver oxidative damage of piglets caused by oxidized oil in the diet of lactating sows. Background technique [0002] Good feeding management is crucial to improving animal production performance, and high-quality feed is an important guarantee for successful breeding. Adding oil to the feed, because of its high energy value, helps fat-soluble vitamins to be transported, absorbed and utilized in the blood, reduces heat consumption, prevents dust, increases feed palatability, and better satisfies the nutrition of pigs need. The value of oil in feed has been gradually realized by people. Adding oil to the feed of lactating sows can increase the content of energy substances in milk, increase lactation, increase energy intake of piglets, increase daily gain and survival rate of piglets, and reduce excessive weig...
