Wheat type piglet 14-35-days-old compound feed and preparation method thereof

Abstract

The invention discloses a wheat type piglet 14-35-days-old compound feed. The compound feed comprises following raw materials in percentage by weight: 45-78% of wheat, 10-28% of soybean meal with the concentration of 46%, 3-11% of puffed soybeans, 5-12% of corn protein powder, 1-3.5% of soybean oil, 0.5-1.5% of premixed material, 0.01-0.03% of liquid complex enzyme and 0.5-1.5% of liquid phytase.A preparation method comprises a crushing step, a granulating step and a spraying step. The wheat type piglet 14-35-days-old compound feed has the beneficial effects of meeting the nutrition requirements of 14-35-days-old piglets, improving the production performance of the piglets and better accelerating the digestion and the absorption of the piglets on the nutrition components, so that the useamount of the corn and the soybean meal is reduced, the feed cost is reduced and the economic benefit is improved.

Description

Technical field [0001] The invention relates to an animal breeding feed containing raw materials derived from plants, animals or minerals, in particular to a 14-35-day-old compound feed for piglets of wheat type containing Chinese herbal medicine additives and a preparation method thereof. Background technique [0002] Affected by traditional feed formulas, corn has been used as the main energy source in energy feed for pigs for a long time. As a result, the supply of corn has become increasingly tight, and the price increase has caused an increase in feed costs. Moreover, judging from the current energy feed supply and demand situation in my country, it is obviously difficult to make up for the energy feed gap by increasing corn production alone. It is estimated that the energy feed gap in my country from 2000 to 2020 will rise from the current 30 million tons to 80 million tons, and my country’s corn production is regionally strong. The total corn output of the six provinces in...

Problems solved by technology

[0004] However, compared with typical energy feed corn, wheat has the following disadvantages: (1) Wheat contains 75% water-soluble dextran, and water-soluble dextran has a high water retention capacity and can absorb water ten times its own weight. It will increase the viscosity of chyme in the intestine and reduce the effect of endogenous enzymes on nutrients, thereby reducing the digestibility of nutrients; (2) Arabinoxylan contained in wheat is the most important anti-nutritional factor in wheat, It increases the viscosity of the contents of the digestive tract. The high viscosity of the intestinal contents realizes its anti-nutritional effect through the following ways: ①Reduce the passing speed of chyme, thereby reducing the feed intake of livestock and poultry. In addition, the high viscosity will make The amount of drinking water of livestock and poultry increases, and the excretion of manure and nutrients will also increase

②The ability of the intestinal tract to mechanically mix the contents is reduced

A number of studies have shown that water-soluble xylan is not only difficult to be utilized by livestock and poultry, but also increases the viscosity of intestinal contents, preventing the digestion and utilization of other nutrients, especially fat and energy, thereby reducing the production performance of livestock and poultry
