Compound biological feed additive

Abstract

The invention relates to a compound biological feed additive. The compound biological feed additive is prepared from the following components in parts by weight: 55-60 parts of kelp powder, 18-20 parts of tea leaf powder, 5-7 parts of cape jasmine fruit powder, 10-13 parts of flaxseeds, 1-3 parts of fish oil, 0.3-0.7 part of living microbial inoculum and 0.1-0.3 part of phytase. According to the additive, the adding amount in complete basal diet of laying hens is 5wt%; compared with the laying hens fed by common chicken feed, the laying rate of the laying hens fed by the additive is obviously improved, DHA, EPA and DPA of produced eggs are improved by 3-5 times, and the color of yolks is improved by 4.23-4.65 unit grades; the guarantee period of the laying hens is prolonged; chicken manure is not smelly so that the environment sanitation of a chicken farm is greatly improved. The additive is slightly modified, can be further applied to livestock feeds for pigs, cattle, fish, shrimps and the like, and has a very wide application prospect.

Description

technical field [0001] The invention belongs to the breeding technology of animal husbandry in the field of agriculture, and specifically relates to fermentation engineering, enzyme engineering, and protein engineering, and uses microbial flora and compounding some beneficial items to prepare a compound biological feed additive. Background technique [0002] With the continuous improvement of people's living standards, high-quality, safe and healthy food is more and more favored by people. Eggs are the most common food in daily life, because eggs are rich in nutrients, and are currently recognized as the most nutritionally balanced food that matches the nutritional needs of the human body. Many scholars at home and abroad add some nutrients needed by the human body to the feed, so that the laying hens will produce eggs after eating. and many other diseases. [0003] The emergence of compound biological feed additives not only improves the utilization rate of feed, but also...

Problems solved by technology

[0004] At present, the chicken feed additives on the market include "chicken Chinese herbal medicine feed additives" invented by Niu Ruiping, etc., as well as "low-fat chicken feed", "rich point multi-dimensional chicken feed", "red and yellow laying hen feed" and "can increase chicken body Feeds that can reduce the content of cholesterol and reduce disease resistance, etc., but although these feed additives can increase DHA, EPA, and DPA to a certain extent, they are still not enough, and the use of these additives has no effect on making chicken manure smelly, and the environmental sanitation of chicken farms situation does not improve

There are still some additives on the market, which only use perilla and flax and other oil crops as feed additives. This type of feed additive has limited production feasibility. The reason is that eggs are enriched with more n-3 series unsaturated fatty acids. , which greatly weakens the antioxidant capacity, resulting in eggs that are easily corrupted and difficult to store
