00 The invention relates to the field of animal husbandry, in particular feed additives in the diets of sheep to improve the quality of wool. A means is known for improving the growth and quality of wool, containing 0i-epical additives and products of chemical and microbiological synthesis of O. However, the use of this tool can lead to metabolic derangements. DL-Methionine is also known to improve the growth and quality of wool. It is introduced into the composition of the feed in a mixture with concentrated feed at the rate of 2.5 g per head per day for 3 months, the increase in wool in length increases by 22%, sheared clean fiber by 220 g, the loss of strength of wool for discharging in the fiber zone, it is less by 30% compared with the same indicators of the control group of sheep that did not receive DL-methionine C2 3. The disadvantage of this remedy is that methionine has antagonists, ethionine and sulfoximine. In view of the great similarity with methionine in animals, they replace it in various biochemical reactions, as a result of which metabolic processes are disturbed. In addition, DL-methionine is expensive and decimal, therefore, under production conditions for large livestock, its use is limited. The purpose of the invention is to improve the growth and quality of wool in sheep without disturbing metabolic processes. This goal is achieved by using sodium formate as a means to improve the growth and quality of wool. Example 1. In the period after the experiment, the proportion of feed in terms of the overall nutritional value of footmarks; in winter, meadow hay is 18.6%, grass granules are 51.2%, grain-fed feeds are 30.2%. For years, green fodder is 54.3%, herbal grana is 29.1%, grain flour is 16.6%. In addition to the basic ration of the young to the experimental group, they received a feed additive sodium formate at a dose of 0.3% by weight of dry matter. In tab. Figure 1 presents data on the qualitative indicators of the experimental ram's wool. From the data table. 1 shows that feeding the specified supplement to young sheep contributes to an increase in the growth of wool in the experimental groups by 13.3 and 26.6%, thinning in the zone of wool fibers grown during the experiment less than in the control group by A, 6% , the length of the wool is better by 2.6 and 7.1%, and the washed wool is 65 and 205 g more, respectively. Example 2. Two groups of rams (10 animals each) in a fine fine-fleece breed for 139 days of winter-stall content, the average body weight when setting up the experience of 24.4-24.7 kg fed the diet and supplement. In the main period of the experiment, the specific weight of feed according to the overall nutritional value in the ration of animals was as follows,%: 38 hay, 34 grass silage, 18 grass granules, 10% grain feeds. In addition to the basic ration, the rams of the experimental group were fed formic acid sodium at a dose of 0.7 by weight of the dry matter of the ration. At this level of feeding, the cut wool was 1.75 kg in the control group, 1.81 kg in the experimental group or 2.8% more; wool growth in length, respectively, 2.69 and 2.98 cm, or 10.7% more. An analysis of the strength of the wool showed that the length of the wool of the fibers in the control group was 8.51 km, in the test group 8.68 km or Bbmie by 2%. In tab. 2 shows the amino acid composition of the wool experimental rams., From the data table. 2 shows that the inclusion in the diet of the specified feed additive contributes to the growth of irreplaceable amino acids in the wool. Thus, the cystine content in the wool of experienced rams above the controls was 3.3 and 12.5%; methionine, respectively, is 8.4 and 13.5% higher. All this causes an increase in the quality indicators of wool. The proposed tool allows to obtain additional wool products (taking into account the improvement in the quality indicators of wool) per 1000 sheep of 1,300 r. And to reduce the costs of obtaining synthetic methionine.
