Compound feed for improving weaned pig fur

Abstract

The invention relates to a compound feed for improving a weaned pig fur. The compound feed comprises the following raw materials: corn, extruded corn, puffed rice, puffed soybean powder, puffed sorghum, peeled soybean meal, whey powder, soybean oil, a coating acidifying agent, phytase, coated zinc oxide, glucose, white sugar, imported fish meal, a vitamin premixing agent, a microelement premixing agent, organic iron, lysine, methionine, threonine, tryptophan, N-carbamylglutamate, an antioxidant, a mildew preventive, a sweetening agent, an antimicrobial peptide, konjaku flour and seaweed meal. The feed disclosed by the invention is reasonable and innovative in formula, and suitable for physiological characteristics of a weaned pig, and meets the comprehensive nutrient requirements of the weaned pig; the effects on the weaned pig fur caused by zinc oxide are reduced; meanwhile, the fur condition of the weaned pig is improved; and the weaned pig can be kept red in skin and bright in fur.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a compound feed for improving the fur of weaned piglets. Background technique [0002] Comprehensive nutrition is a major factor in keeping pigs healthy. A ruddy skin and shiny coat indicate that the pigs are healthy and free from disease. Comprehensive feed nutrition From a nutritional point of view, energy, protein, fat, carbohydrates, vitamins, minerals and water are all key factors for pig growth and production. Under normal circumstances, the nutrients provided in the feed can meet the needs of the pigs for the above nutrients, and the pigs will have ruddy skin and bright coat color. However, in production, some farmers often report that the pig’s skin is not rosy, the hair is not bright, and the hair is long and loose, especially after the piglets are weaned, and many farmers also regard the pig’s skin as an important criterion for judging whether the feed is good or not. ...

AI Technical Summary

Problems solved by technology

High doses of ordinary zinc oxide can effectively prevent diarrhea in piglets, but long-term use of high zinc will seriously affect the absorption of other trace elements, resulting in unbalanced absorption of copper and iron, resulting in a decrease in the potency of other nutrients, which will destroy the homeostasis mechanism in the body , resulting in pale skin, rough and curly coat, anemia and other phenomena in piglets

In addition, high-zinc diets cause most of the zinc to be excreted into the environment with feces, causing environmental pollution. The zinc content in the soil exceeds the standard. From the perspective of the food chain, it will eventually cause harm to human health

[0004] The ideal amino acid pattern also has a great influence on the fur of weaned piglets. Each amino acid is like each plank on a wooden barrel. The higher the balance of each amino acid, the more effectively the digestibility of protein in feed can be improved, and excess amino acids can be reduced. The impact of nitrogen-containing substances remaining in the body on the fur; the ruddy skin is mainly due to the content of hemoglobin in blood and muscles, and hemoglobin is mainly composed of iron. Iron in inorganic form is difficult to absorb or has a low absorption rate. It is necessary to find a way to absorb Organic iron with a high rate and auxiliary additives to promote the absorption of organic iron; at the same time, the cellulose content in the diet of weaned piglets is generally low, and the available dietary fiber is often insufficient, especially the dietary fiber that has an effect on the fur.
