Problems solved by technology

[0005] In view of the above reasons, when young minks just start to eat during the weaning period, diarrhea is often caused due to the lack of digestive enzymes, which not only hinders the healthy growth of young minks, reduces the absorption rate of nutrients for young minks, and even causes diarrhea in severe cases. mink death
Since there is no unified breeding standard for minks, the above-mentioned problems need to be solved urgently

[0032] Preferably, the above-mentioned mink feed, the feed contains 2 wt % ~ 4 wt % of the mink feed additive;

[0033] More preferably, the feed contains 2.5 wt % to 3.5 wt % of the mink feed additive.

[0034] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosed embodiments belong. Although methods and materials similar or equivalent to t...

Embodiment 1

[0038] Present embodiment provides a kind of mink feed additive:

[0039] Mink feed additive Artemisia annua and enzymes;

[0040] The whole plant of Artemisia annua is pulverized with a pulverizer, and the particle size is 0.6~1.0cm for later use;

[0041] Dilute the enzyme preparation with puffed corn at a ratio of 1:5, and then mix it with Artemisia annua. Based on 1 kg of Artemisia annua, it includes 100,000 units of cellulase, 500 units of lipase, 2 million units of protease and 2,000 units of pectinase.

Abstract

The invention relates to the technical field of animal breeding, in particular, to a mink feed additive and a preparation method thereof, and a mink feed containing the mink feed additive. The mink feed additive includes: Artemisia annua and enzymes; based on 1 kg of Artemisia annua, the enzymes include 10,000-100,000 units of cellulase, 500-8,000 units of lipase, 25-2,000,000 units of protease and 2,000-2,000,000 units of pectinase. 10,000 units. The feed additive does not contain chemical substances and hormones, and can provide necessary enzymes for minks, especially juvenile minks, thereby avoiding diarrhea in minks, promoting the development of the digestive system of juvenile minks, and making minks grow faster and have brighter fur.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a mink feed additive and a preparation method thereof, and mink feed containing the mink feed additive. Background technique [0002] Mink ( Mustula Vison ) is a precious fur animal in my country. Mink fur is one of the "three major furs" in the world and enjoys a high reputation in the international fur market. In animal taxonomy, mink belongs to Mammalia, Carnivora, Mustelidae, and Mustela genus. It is a small fur animal with very high economic value. Mink originates from North America. Due to the considerable economic benefits it brings, Europe once maintained an annual increase of 25 million minks. At present, most of the minks widely raised in countries around the world and in my country are American minks. [0003] As a strict carnivore, mink differs from omnivores and herbivores mainly in the utilization rate of feed digestion. The incisors of mink are short, a...
