Easily digestible distiller's grain duck feed and preparation method thereof

Abstract

The present invention discloses an easily digestible distiller's grain duck feed. The duck feed is prepared from the following raw materials in parts by weight: 80-90 parts of wheat bran, 20-25 parts of middlings, 5-10 parts of garlic powder, 20-25 parts of mung bean pods, 10-15 parts of fish meal, 4-7 parts of zophobas atratus powder, 20-25 parts of honey peach juice, 3-5 parts of dried persimmon frost, 3-6 parts of honey, 11-13 parts of sesame seed oil, 70-80 parts of distiller's grains, 1-2 parts of radix scrophulariae, 1-2 parts of black tea, 1-2 parts of peony flowers, and an appropriate amount of cellulase and water. The easily digestible distiller's grain duck feed is prepared by using the wheat bran and distiller's grains as main raw materials, the distiller's grains are subjected to shelling treatment, so that the content of crude fibers is greatly reduced and the contents of crude protein and crude fat are improved. Cereal chaffs are subjected to enzymatic hydrolysis, the resources are fully used, the resource wastes are avoided, the prepared feed is easily digestible, the feed digestion and utilization are improved, the ducks are fast in growth, the growth cycles of the ducks are shortened, and at the same time, the duck is delicate in meat quality, and good in quality.

Description

[0001] technical field [0002] The invention relates to the technical field of feed, in particular to an easily digestible distiller's grain duck feed and a preparation method thereof. Background technique [0003] 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, resultin...

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%. %
