Piglet compound feed composition with fermented rapeseed meal

Abstract

The invention discloses a piglet compound feed composition with fermented rapeseed meal. The piglet compound feed composition contains the following raw material components in percentage by weight: 40%-60% of corns, 8%-15% of puffed corns, 3%-5% of bran, 1%-3% of freshwater fish meal, 15%-20% of bean pulp, 5%-10% of fermented rapeseed meal, 0.2%-0.5% of dicalcium phosphate, 0.5%-1% of limestone powder, 0.1%-0.3% of 98% lysine, 0.01%-0.03% of methionine, 0.05%-0.1% of choline chloride, 0.2%-0.5% of salt, and 1%-1.5% of premixes. The compound feed disclosed by the invention is based on a normal corn and bean pulp piglet feedstuff formula, and adopts the fermented rapeseed meal to replace equivalent 8% bean pulp to supplement part of artificially synthesized amino acid; and partial bean pulp is replaced by the fermented rapeseed meal, the pig production performance is not affected, and the weight gaining cost of pork pigs is lowered at the same time.

Description

technical field [0001] The invention relates to an animal feed, in particular to a piglet compound feed and a preparation method thereof. Background technique [0002] The usual pig compound feed is fed with 5% premix plus feed ingredients such as soybean meal, fish meal, bran, corn, or corn gluten meal. [0003] my country is the world's largest rapeseed producer. The planting area of ​​rapeseed accounts for more than 40% of the total area of ​​oil crops in the country, and the output accounts for more than 30% of the total output of oil crops in the country. Since the 1980s, my country has become the country with the largest rapeseed production in the world. The output in 11 years reached more than 12 million tons, and the output of rapeseed meal was about 8 million tons. [0004] The crude protein content of rapeseed meal is about 37%, which is an important protein feed resource. However, the crude fiber content of rapeseed meal is relatively high, some reaching more t...

AI Technical Summary

Problems solved by technology

However, the crude fiber content of rapeseed meal is relatively high, some reaching more than 18%; more than 60% of the total phosphorus content is phytate phosphorus, which is not conducive to absorption and utilization

[0005] In addition, rapeseed meal also contains toxic substances and anti-nutritional factors such as glucosinolates, tannins, sinapine, saponin, etc., which not only affect its nutritional value, but also endanger the health of animals and cause animal poisoning if they are directly eaten by animals in large quantities Even death, affecting the safety, palatability and nutrient utilization of feed, thus limiting its use in livestock and poultry diets
