Forage feed used in nonpregnant stage of boars

Abstract

The invention discloses a forage feed used in the nonpregnant stage of boars. The feed comprises the materials by weight percent: 60-70% of forage powder, and the balance being auxiliary materials, wherein the auxiliary materials comprise the materials by weight parts: 20-30 parts of corn, and 5-15 parts of bran. As a forage material is added in an existing forage feed used in the nonpregnant stage of the boars, the secretion of various digestive glands of the boars can be stimulated, and after the forage powder is added, the forage is used for supplementing the insufficient of the contents of protein and calcium in the forage powder, and supplementing vitamins and mineral substances; the feed has the characteristics that the utilization rate of the forage powder is increased, the digestion rate is high, and the nutritive value is improved. As the forage feed adopting the materials is used for the boars in the nonpregnant stage, the fertilization rate of the boars is increased, and the heath conditions of the boars can be improved.

Description

technical field [0001] The invention relates to a pig feed, in particular to a forage feed for breeding pigs in the empty pregnancy stage. Background technique [0002] China's pig industry is entering a stage of high-speed development. Pig feed directly affects the yield and quality. Traditionally, fish meal, meat and bone meal, soybean meal, corn, and wheat are the main feedstuffs used in the breeding of meat pigs and boars. raw material. In the production of hog and boar feed, the source of raw materials has become a major problem: overfishing in the sea has resulted in a sharp reduction in fishmeal production, and the main protein in the feed is facing unsustainable conditions; the prices of traditional feed grains such as corn, soybeans, wheat, and rice are soaring, and the supply of goods is in short supply. ; Excessive use of feed additives, abuse of chemical growth hormones and chemical antibiotics, resulting in excessive residues, has become a "killer" of food safe...

AI Technical Summary

Problems solved by technology

In the production of hog and boar feed, the source of raw materials has become a major problem: overfishing in the sea has resulted in a sharp reduction in fishmeal production, and the main protein in the feed is facing unsustainable conditions; the prices of traditional feed grains such as corn, soybeans, wheat, and rice are soaring, and the supply of goods is in short supply. ; Excessive use of feed additives, abuse of chemical growth hormones and chemical antibiotics, resulting in excessive residues, has become a "killer" of food safety; improper feed formula, indigestion, eutrophication of feces, making it fermented to produce a large amount of ammonia and hydrogen sulfide odor body, followed by excretion and become a source of environmental pollution

[0003] The problem of feed has long plagued the pig breeding industry, and cost is the key. In feed, for every 10% increase in the proportion of protein raw materials, the feed cost will increase by 8%. l3%, under market competition, it is often difficult for farmers to bear

[0005] The above feed is not suitable for breeding pigs in the empty pregnancy stage
