Distillers' grain containing duck special feed and preparation method thereof

Abstract

The present invention discloses a distillers' grain containing duck special feed which is made of the following raw materials in parts by weight: 20-30 parts of cottonseed cakes, 40-50 parts of wheat bran, 20-30 parts of cassava, 10-13 parts of mulberry buds, 5-9 parts of blanched garlic leaves, 15-20 parts of carrots, 4-5 parts of black tea powder, 10-14 parts of sunflower seed hulls, 4-5 parts of curry powder, 3-4 parts of almond powder, 10-15 parts of coprinus comatus, 10-15 parts of agrocybe aegirit sticks, 12-14 parts of sesame oil, 70-80 parts of distillers' grains, 1-2 parts of hedyotis diffusa leaves, 2-3 parts of radix et caulis acanthopanacis senticosi, 1-2 parts of radix rehmanniae, an appropriate amount of cellulase, and an appropriate amount of water. The distillers' grain containing duck special feed is prepared by using the cottonseed cakes, wheat bran, cassava and distillers' grains as the main raw materials. The distillers' grains are subjected to a shelling treatment, which greatly reduces the crude fiber content and increases the crude protein and crude fat content. The rice hulls are subjected to an enzymatic treatment to fully use the resources and avoid the waste of resources. The prepared food is reasonable in components and ratio and comprehensive and rich in nutrition, increases the appetite of the ducks, and improves the disease resistance of the ducks.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a special feed for ducks containing distiller's grains and a preparation method thereof. Background technique [0002] Distiller's grains are by-products of the brewing industry. According to statistics, 12.5 million tons of grain are used for brewing in my country every year, and 13.2 million tons of distiller's grains are produced. The air-dried distiller's grains contain 17% protein, and the amino acids are complete in variety and balanced in proportion. It is a high-quality protein feed source. If these distiller's grains are processed into feed, 500,000 tons of dried distiller's grains can be produced annually. The distiller's grains contain 35.6% of rice husk and 18.6% of crude fiber, which makes the distiller's grains rough, poor in palatability to animals, and poor in nutritional and feeding value, which seriously affects the feeding value of distiller's grains, resulting i...

Problems solved by technology

The distiller's grains contain 35.6% of rice husk and 18.6% of crude fiber, which makes the distiller's grains rough, poor in palatability to animals, and poor in nutritional and feeding value, which seriously affects the feeding value of distiller's grains, resulting in a feeding rate of less than 50%. %
