Embodiment Construction

[0006] The basal diet formula and nutritional levels of minks when cysteamine is added are as follows:

[0007] Regular feed formula and main nutrient concentration of mink in growth period 1 (%MJ / kg)

[0008]

[0009] Note: 1. Additive formula ( / kg air-dried feed): Methionine + Cystine 9.5g, Vitamin D 35 International Units (IU), Vitamin E 0.5mg, Vitamin B 1 1.5mg, vitamin B 2 3.7mg, pantothenic acid 7.4mg, vitamin B 6 1.8mg, vitamin PP 9.6mg, folic acid 0.2μg, appropriate amount of flavoring agent, antioxidant, etc. plus carrier and stone powder diluent to prepare a product with a dosage of 0.5%.

[0010] The corn flour and soybean flour in the feed formula for mink in the growing period are first expanded, and the sea fish, beef head, beef viscera and 8.7% water are boiled, and other ingredients are added after cooling slightly, and then the required amount of cysteamine is added. Add the hydrochloride loading body after dilution, mix well and then feed.

Abstract

The invention discloses an optimal application method of cysteamine in feedstuff of a mink in a growing period and belongs to the technical field of agricultural technique A01 / A01K; the technical problem to be solved is that the existing feedstuff resource is used for feeding the mink in the growing period safely and effectively; the technical proposal solving the problem is that simple compound cysteamine exhausts somatostatin, thus improving the amount of important hormone which is related to the growth of the mink, such as growth hormone, etc. and achieving the aim of improving the quality of the fur of the mink effectively; aiming at overcoming the defects that the toxic hazard to the mink caused by excessive cysteamine and the effect is not obvious when the dosage is low, experiments proves that the effect is best according to that 70mg of cysteamine is added in the feedstuff by 1 kg of the weight of the mink every five days, thus leading the conversion rate, the body weight and the fur quality of the feedstuff to be improved greatly.

Description

technical field [0001] The technical field of A01 / A01K belongs to the wild animal feed in the wild animal breeding in the agricultural field. Background technique [0002] At present, there is no corresponding national nutritional standard to follow in the process of mink breeding in my country. Therefore, in the actual breeding process of mink, nutritional metabolic diseases often occur due to unreasonable nutrition, which makes the degradation of imported mink species very serious. At the same time, the price of mink feed raw materials is high, procurement is difficult, the cost of fresh feed storage is too high, the quality is poor, and the utilization rate of feed is extremely low, which makes the overall economic benefits of breeding low. The background technology of this patent is to use the existing feed resources in such a breeding environment and scientifically add cysteamine to deplete the growth hormone to increase the growth hormone level and achieve a substantia...
