Problems solved by technology

However, non-starch polysaccharides (NSP) in wheat are high in anti-nutritional factors, and most of them are soluble, so their use in feed production is often restricted.
At present, the most effective way to reduce feed NSP content is to add enzyme preparations in the feed, but the enzyme preparations added in the prior art are relatively single, only endo-xylanase or endo-B-glucanase, only It can effectively decompose arabinoxylan and β-glucan in wheat non-starch polysaccharide (NSP), but wheat non-starch polysaccharide (NSP) also contains cellulose and pectin that cannot or are difficult to be decomposed by monogastric animals etc. Except for energy, other nutrients of wheat are higher than that of corn, and it contains higher crude protein, which brings a greater burden to pig stomach and has low digestibility

specific Embodiment 1

[0019] A pig feed formula, comprising 30% by mass of wheat, 50% of corn, 5% of pine needle powder, 10% of premix and 5% of wheat concentrate, wheat concentrate comprising 70% by mass of Soybean meal and 30% wheat-specific enzymes, including beta-glucanase, pectinase, amylase and protease. The ratio between β-glucanase, pectinase, amylase and protease in wheat-specific enzymes is 2:1:0.5:0.5. Wheat-specific enzymes use single-enzyme compound technology, and all single enzymes use excellent strains of liquid submerged fermentation technology. Endoxylanase can be substituted for β-glucanase. This formula contains less wheat and is suitable for feeding nursery pigs.

specific Embodiment 2

[0020] A pig feed formula, comprising 50% wheat, 30% corn, 6% pine needle powder, 7% premix and 7% wheat concentrate, the wheat concentrate includes 65% by mass Soybean meal and 35% wheat-specific enzymes, including beta-glucanase, pectinase, amylase and protease. The ratio between β-glucanase, pectinase, amylase and protease in wheat-specific enzymes is 2:1:0.5:0.5. Wheat-specific enzymes use single-enzyme compound technology, and all single enzymes use excellent strains of liquid submerged fermentation technology. Endoxylanase can be substituted for β-glucanase. This formula contains more wheat and is suitable for feeding growing pigs.

specific Embodiment 3

[0021] A pig feed formula, comprising 70% by mass of wheat, 10% of pine needle powder, 10% of a premix and 10% of wheat-specific concentrates, the wheat concentrates comprising 60% by mass of soybean meal and 40% of Wheat-specific enzymes, wheat-specific enzymes include beta-glucanase, pectinase, amylase and protease. The ratio between β-glucanase, pectinase, amylase and protease in wheat-specific enzymes is 2:1:0.5:0.5. Wheat-specific enzymes use single-enzyme compound technology, and all single enzymes use excellent strains of liquid submerged fermentation technology. Endoxylanase can be substituted for β-glucanase. This kind of formula wheat completely replaces corn as feed and is suitable for feeding fattening pigs and sows.

Abstract

The invention discloses a pig feed formula and relates to the technical field of raising pig. The pig feed formula comprises, by quality, wheat from 30% to 70%, corn from 0% to 50%, pine needle powder from 5% to 10%, premix compound from 5% to 10% and concentrated feed special for the wheat from 5% to 10%. The pig feed formula is characterized in that the concentrated feed special for the wheat comprises, by quality, bean pulp from 60% to 70% and enzyme special for the wheat from 30% to 40%. The enzyme special for the wheat comprises beta-dextranase, pectinase, amylase and protease. The pig feed formula has the advantages of improving flexibility of the formula, improving metabolic energy of the wheat, improving crude protein apparent digestibility of the wheat due to the fact that the wheat can partly or overall replace the corn in formula feed, narrowing the gap between the corn and the wheat, reducing cost of feed on the premise of maintaining production performance of animals, relieving viscosity effect of the wheat, adjusting intestinal tract micro-ecological faunal, improving intestinal health, keeping excrement dry, reducing excrement excretion quantity and pollution of environment and product.

Description

Technical field: [0001] The invention relates to the technical field of pig raising, in particular to a pig feed formula. Background technique: [0002] Wheat was mainly used as human food in the past in my country, and its processed by-products, wheat bran and flour, were used as feed for livestock and poultry. With the gradual increase of my country's wheat production, the increase of grain reserves year by year, and the entry of WTO, the impact of the influx of imported wheat has caused the price of wheat to decline. At the same time, with the rapid development of animal husbandry, the amount of feed is constantly increasing, and a large amount of corn is also consumed in the manufacture of starch and lysine. The price of corn, which was mainly used as energy feed in the past, continues to rise. Wheat gradually replaces corn as energy feed to reduce feed costs. , Improving economic benefits has become a development trend. However, non-starch polysaccharides (NSP) in whe...
