Pig feed additive capable of protecting nutrient substance contained in feed

Abstract

The invention discloses a pig feed additive capable of protecting nutrient substances contained in feeds, and belongs to the field of feed additives. The pig feed additive disclosed by the invention can reduce the oxidation and denaturation of vitamins and fats which are contained in the feeds and the destructive effect of other reactions on the vitamins and the fats by utilizing the properties of a chicory extract and the combined effect with other substances; the pig feed additive disclosed by the invention can inhibit the generation of phalaenae and cadelles in the feeds in such a way thatprocessed isoflavoues aglycone, potassium diformate, maltose and octyl gallate achieve higher killing effect on the ova of the phalaenae and the cadelles and the like by being used together with the chicory extract, thereby reducing the eating of pests on nutritional ingredients contained in the feeds and reducing the loss of the nutritional ingredients, such as proteins, the fats, the vitamins, and the like which are contained in the feeds; by eating the pig feed additive prepared by the invention, live pigs can be previously fattened, so that the breeding cost is reduced, and the economic benefit is enhanced; and the pig feed additive disclosed by the invention can reduce the loss amount of the nutritional ingredients, such as the proteins, the fats, the vitamins, and the like which arecontained in the feeds in the storing process, thereby ensuring the nutrition value of the feeds.

Description

technical field [0001] The invention relates to a feed additive for pigs, in particular to a feed additive for pigs capable of protecting nutrients in feed, and belongs to the field of feed additives. Background technique [0002] There are many types of feed, but from the perspective of its composition and processing process, there are mainly by-products of grain and oil processing and compound feed. These feeds have different storage characteristics due to different raw material composition and physical shape, but generally have the following characteristics: [0003] 1) High starch and protein content, easy to absorb moisture and return to moisture: these ingredients have hydrophilic properties, so the feed has strong moisture absorption capacity. [0004] 2) High fat content, easy to oxidize and become rancid: especially the by-products of grain and oil processing have high fat content, such as rice bran, which generally has a fat content of 17%-18%. Under the action o...

Problems solved by technology

[0004] 2) High fat content, easy to oxidize and become rancid: especially the by-products of grain and oil processing have high fat content, such as rice bran, the fat content is generally 17%-18%

Under the action of lipolytic enzymes, the fat in the feed is easily decomposed, resulting in a large increase in free fatty acids and a higher acid value, thus deteriorating the quality of the feed

[0005] 3) Exposed nutrition, prone to pests: After the raw materials of processed feed are mechanically crushed, they lose the protection of the cortex and the nutrients are exposed

However, some anti-mold antioxidants will produce special odor, which will affect the palatability of feed
