Abstract

FIELD OF THE INVENTION The invention relates to fur farming, in particular to the cultivation of mink. The purpose of the invention is to improve the quality of the skins. A mixture of diammonium phosphate and phosphogypsum is introduced into the basic ration of animals in the following ratio. wt.%: - diammonium phosphate 10-30; phosphogypsum else. The resulting mixture is introduced into the diet in the amount of 0.5-1.0 g per 1 head per 1 day. The proposed method allows to increase the size of skins to 10.5%, to improve their quality on average up to 30%. 1 tab.

Description

FIELD OF THE INVENTION The invention relates to fur farming, in particular to the cultivation of mink.

It is known to improve the growth and quality of mink fur, containing water-soluble sodium salts of chlorophyllin (ed.St. No. 548254, class A 23 K 1/16, 1977).

The disadvantages of chlorophyllins are the complexity of the production technology, the relatively high cost of the drug with its average effectiveness.

It is known to use the synthetic analogue of phytohormones tris (2-hydroxyethyl) ammonium 0-cresoxyacetate as a means to accelerate the maturation of the winter hair of young minks (auth. No. 121405. class A. 23 K 1/16, 1986).

The disadvantages of the synthetic phytohormone analogue Tris (2-hydroxyethyl) ammonium 0-kresoxyacetate are the complexity of the production technology, the scarcity of the raw material and the high cost of the drug at a relatively low efficiency.

The most common preparation for stimulating fur production in minks is polfamix,

containing vitamins and microelements (F.G.Nabiyev and others. Drugs and biological preparations in fur farming. Reference book, 1986, p. 67).

However, when using lolfamix, there is a slight improvement in the quality of fur of mink, an expensive, imported preparation.

The purpose of the invention is to improve the quality of the skins. -

To improve the growth and quality of fur, the minks according to the invention use a mixture of diammonium phosphate and phosphogypsum as a hair growth stimulator in the following ratio, wt.%: Diammonium phosphate 10-30, phosphogypsum the rest, while the resulting mixture is introduced into the diet in the amount 0.5-1.0 g per head in 1 day.

The proposed method differs from the prototype in that. that the stimulator contains a simple set of vitamins and several trace elements, and the mineral components: diammonium phosphate and phosphogypsum. These components allow one to make a conclusion on the compliance of the invention with the novelty criterion.

The feed supplement from diammonium phosphate and phosphogypsum is known as a means to improve the quality of the egg shell in laying hens (ed. No. 1423094, class A 23 1/175, 1988). As a stimulator of fur growth, it was proposed for the first time. Thus, the invention meets the criterion of significant differences.

PRI me R 1. Stimulation of growth and quality of fur mink.

The tests were carried out in the fur farm Somovsky of the Voronezh region in September-October 1989. Five groups of minks, 80 animals each, were taken in the experiment. The minks of the first four groups were added to the main ration of combidaf-1, respectively, in doses, g per head: 0.3; 0.5; 1.0; 1.5. The minks of the first group received 5% by weight of diammonium phosphate and 95% of phosphogypsum, the second group - 10% of diammonium phosphate and 90% of phosphogypsum, the third group of -30% of diammonium phosphate and 70% of phosphogypsum and the fourth group - 40% of diammonium phosphate and 60% of phosphogypsum . The fifth group of animals was the control group; polmix was introduced into the feed. Each group of minks included up to 40% females.

At the end of the experiment, the animals were killed, the size of the skins was determined, their quality was evaluated. The results are shown in the table.

As a result of morpho-biochemical blood tests, it was found that a decrease in pyruvic acid as an inverse indicator of the body's supply of vitamin Vl and an increase in sulfur-containing free amino acids participating in fur formation (cystine, methionine, lysine) are observed in animals of all experimental groups, but are most pronounced in the third group .

The use of diammonium phosphate and phosphogypsum to improve the growth and quality of fur in minks has advantages over polfamix. The proposed tool allows to increase the size of the skins to 10.5%, to improve their quality on average, to DOZ%.

Formulas of the method of growing minks, which include the introduction of a growth stimulator to the basic ration of animals, characterized in that, in order to improve the quality of the skins, a mixture of diammonium phosphate and phosphogypsum, taken in the following ratio, is used as a hair growth stimulator. %: diammonium phosphate 10-30, phosphogypsum the rest, while the resulting mixture is introduced into the diet in the amount of 0.5-1.0 g per 1 head per 1 day.
