Feed capable of improving production performance of broiler chickens

Abstract

The invention provides a feed capable of improving the production performance of broiler chickens. The feed is prepared from following raw materials in parts by weight: 400 to 600 parts of corn, 100 to 150 parts of soybean meal, 60 to 120 parts of rapeseed meal, 50 to 100 parts of fermentation product of earthworm, 10 to 30 parts of brewer's grain, 50 to 100 parts of peanut meal, 1 to 3 parts of composite amino acid, 2 to 4 parts of composite enzyme, 1 to 2 parts of trace element, 0.5 to 1 part of phytase, and 5 to 10 parts of calcium hydrogen phosphate; wherein the fermentation product of earthworm is prepared by the following steps: taking earthworms as the raw materials, fermenting earthworms by lactobacillus casei and lactobacillus acidophilus, then fermenting earthworms by bifidobacteria, filtering the fermentation product to obtain filtrate, and finally concentrating and drying the filtrate to obtain the feed. The feed has the advantages that the protein utilization rate is increased and the nutrients of chicken meat are enriched.

Description

technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a feed for improving the production performance of broilers. Background technique [0002] In recent years, with the increase in the number of poultry breeding, the pressure of environmental protection and energy saving is increasing. The pollution of the poultry industry mainly comes from the excreta of nitrogen, phosphorus, trace elements, etc. These substances mainly come from undigested feed in the feed. Nutrients. These harmful substances not only destroy the environment of the chicken house, but also pose a great threat to the health of poultry, increase the incidence of poultry disease, and reduce the economic benefits of poultry farmers. Hazard to human health. [0003] From the current utilization of protein feed, it can be found that the utilization efficiency of protein in protein feed is not high, and protein waste is serious, especially the protein utiliza...

AI Technical Summary

Problems solved by technology

So far, the shortage and waste of protein feed still exist in the production of compound feed. The typical performance is that the energy of compound feed does not reach the level specified in the standard, and the protein content exceeds the level specified in the standard, resulting in low energy and high protein, and waste. protein

[0004] In the production of some commercial batch materials, in order to highlight the high quality, the increase of protein content is promoted as a highlight, which is actually a waste of protein

Some low-cost feeds produced using unconventional protein feeds such as rapeseed meal, cottonseed meal, etc. have not solved the problem of low quality and low efficiency of the raw materials themselves, and their feeding effect is not good, especially this low-cost feed, palatability is common Not good, animal feed intake is low, production performance is lower, and the feeding period is prolonged, resulting in a serious waste of protein. Obviously, after the unconventional protein feed has solved the availability in theory, it is further necessary to solve the problem of low quality and low efficiency utilization

[0005] In the development of feed resources, the research on improving feed utilization efficiency is generally solved by balancing amino acids in the formula design of compound feed. However, the current feed formula design in production generally only balances lysine and methionine. The most wasted amino acids are leucine, phenylalanine + tyrosine and arginine. These amino acids are more than 3 times higher than required in general feed formula design, which is equivalent to wasting about 4% of crude protein On the other hand, even if the amino acids are balanced with different sources of feed in the formula, due to the different sources, the efficiency of protein digestion and utilization is different, and the actual effect of balanced amino acids is not ideal.
