Problems solved by technology

Cotton meal and sunflower meal have high oil content and poor amino acid utilization
Palm meal is a by-product of palm kernel shelling and oil extraction. It is rich in nutrients such as protein, crude fat, non-starch polysaccharides, phosphorus and calcium elements, etc., but because it is also rich in fiber and contains more non-starch polysaccharides As an anti-nutritional factor, it is not easy to be digested and absorbed by animals, which makes its poor digestibility, which leads to limited application, affects palatability, and reduces the absorption of nutrients in the animal intestines

Abstract

The invention relates to a biological feed additive and a preparation method and application thereof. The feed additive comprises the following components in parts by weight: 5-9 parts of palm meal, 0.3-1.5 parts of a special compound enzyme, 0.5-1 part of compound probiotic powder and 0.2-0.8 part of tannic acid. The preparation method comprises the following steps: crushing the palm meal, uniformly mixing the special compound enzyme, the compound probiotic powder and the tannic acid under stirring, adding the crushed palm meal, and carrying out uniform mixing to obtain the feed additive. Thefeed additive is applied to a pig feed, and the feed additive accounts for 2-4.5 wt% of the main material of the feed. Compared with the prior art, the biological feed additive of the invention has the advantages that resource utilization of the palm meal can be realized; and through bacterium-enzyme synergistic effect, substances which cannot be utilized by animals in the raw materials can be converted into nutrient substances which are digested and absorbed by animals, so the utilization rate of the feed and the potential application value of the palm meal are remarkably improved, feed costis reduced, and culture benefits are improved.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a biological feed additive and its preparation method and application. Background technique [0002] As the price of corn, soybean meal and other raw materials continues to rise, it has put pressure on the development of animal husbandry. Many farmers hope to find a low-priced product to replace some corn, soybean meal and other raw materials. Cotton meal and sunflower meal have higher oil content and poor amino acid utilization. Palm meal is a by-product of palm kernel shelling and oil extraction. It is rich in nutrients such as protein, crude fat, non-starch polysaccharides, phosphorus and calcium elements, etc., but because it is also rich in fiber and contains more non-starch polysaccharides As an anti-nutritional factor, it is not easy to be digested and absorbed by animals, so its poor digestibility leads to limited application, affects palatability, and reduces the a...
