Fermented feed for cattle and sheep and preparation method of fermented feed

Abstract

The invention relates to the technical field of livestock product breeding, in particular to a fermented feed for cattle and sheep and a preparation method of the fermented feed. The fermented feed for cattle and sheep is prepared from, by percentage, 28-32 wt% of soybean meal, 18-22 wt% of cottonseed meal, 12-17 wt% of corn protein powder, 8-12 wt% of oat middlings and 20-30 wt% of a mixed bacterial liquid. The preparation method of the mixed bacterial liquid comprises the steps that saccharomyces cerevisiae, bacillus subtilis, lactobacillus plantarum and pediococcus pentosaceus are cultured and rejuvenated separately, 3-8 wt% of chilli meal is added in all strain culture mediums, and the rejuvenated strains are cultured to obtain the mixed bacterial liquid. A culture medium and the mixed bacterial liquid are put in an inner membrane bag with a breathing valve, and fermentation is conducted for 5-7 days at 15-25 DEG C to obtain the fermented feed. The prepared feed is high in protein content and easy to absorb and can replace partial protein raw materials, the manual addition of nitrogen in the feed is reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of livestock breeding, and more specifically relates to a fermented feed for cattle and sheep and a preparation method thereof. Background technique [0002] With the increase of the world's population, the food consumption is also increasing; coupled with the ban on toxic pesticides, the pests and diseases are raging, causing a large amount of food production to be reduced; coupled with the world's fishery resources are becoming more and more scarce, the production of animal protein feed raw materials has dropped sharply, resulting in feed Raw material prices continue to rise, and there is a tendency to continue to rise, which will eventually lead to continuous increases in breeding costs. How to save the cost of feed, which accounts for 80% of the cost of farming, and seek effective processing methods for feed and feed raw materials have become the key to farming. [0003] At present, the main problems fa...

AI Technical Summary

Problems solved by technology

[0003] At present, the main problems faced by the cattle and sheep breeding industry can be summarized as follows: First, the high cost of feed and the lack of high-quality feed

Homogeneous feed formula, conventional feed raw materials, lack of high-quality roughage, a large amount of unconventional energy and protein raw materials, plant organic calcium and phosphorus, etc. have not been fully utilized
