Composite feed for livestock and poultry

Abstract

The invention relates to the field of animal feed, in particular to compound feed for beasts and birds. The compound feed comprises the following components in weight portion: 75 to 85 portions of corn stalk, 18 to 22 portions of corn meal, 8 to 15 portions of bean cake, 0.4 to 0.8 portion of salt, 2 to 5 portions of spirulina powder, 1 to 5 portions of calcium biphosphate and 0.01 to 0.05 portion of citric acid. The corn stalk, the corn meal and the bean cake are subjected to superfine grinding, and then mixed with the salt, calcium biphosphate powder, citric acid powder and the spirulina powder according to a proportion, stirred evenly, sterilized, cooled, and packaged to obtain the compound feed. The compound feed can balance microbe groups in intestines and stomachs of the beasts and the birds, provides balanced and rich nutrition, has low cost and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of animal feed, in particular to a compound feed for livestock and poultry. Background technique [0002] At present, the main source of domestic plant protein feed is soybean meal, and the main source of animal protein feed is fish meal and silkworm chrysalis. However, protein feed in my country is not only in short supply but also expensive, and high doses of trace elements and antibiotics are added to the feed in the market, so that the rapid growth of livestock and poultry. However, the disadvantages that follow are that the balance of the gastrointestinal microbial flora of livestock and poultry is out of balance, and production performance declines or diseases occur. Under normal circumstances, the dominant population in the intestinal tract of animals is anaerobic bacteria, accounting for more than 99%, mainly including Bacteroides, Bifidobacteria, Lactobacillus, Digestobacillus, Eubacterium, etc., while aerobic...

AI Technical Summary

Problems solved by technology

If the dominant population changes, the above-mentioned obligate anaerobic bacteria will decrease significantly, while aerobic bacteria and facultative anaerobic bacteria will increase. At this time, the immunity of livestock and poultry will decline, leading to the occurrence of diseases

The research of animal feed also has a lot of reports, as publication number is that CN1134788A patent application proposes a kind of concentrated feed for pigs, and publication number is that CN1129073A patent application proposes a kind of pig high-protein feed granulation method, and publication number is that CN1191019C patent proposes a kind of price cheaper Animal feed and its preparation method, but can provide balanced nutrition for animals, but also allow farmers to accept the price, that is to say, economical, nutritious and environmentally friendly feed is rarely reported
