they were giving a full rate of vitamin A due to the addition of synthetic vitamin A and carotene feed, group III, in addition, received the beats drug in the above dose.

Fecundity of ewes when feeding the beatris drug

Determination of the hormonal activity of extracts from the bitrice preparation was carried out in experiments on rooster chickens using a method based on the study of changes in secondary sexual characteristics (comb mass) when administered to experimental chickens there hormone-containing animals, their items (V).

The experiment was carried out in a VIVAR vivarium on day-old chick-cocks of white leggorn breed. The content of chickens is cellular, feeding according to the existing norms (cottage cheese, millet, eggs, green grass). An extract was prepared from the preparation of beats, which was dissolved in vegetable oil. The dose of the extract solution in the processing of the chickens was equal to 0.1 ml. Chickens before experience were divided into groups of 7 pieces each. In the experimental group, the comb was treated with 0. P and smeared with bitrice extract. In the control group - O. R. and vegetable oil.

The results of the experiment are presented in table. 2

Example 3. The experiments were conducted on ewes according to the same scheme as in sows. The results are presented in table 3.

At the end of the experiment, a control slaughter of chickens was carried out and the weight of the ridge was weighed, the results of which are presented in Table. four.

From the data table. 4, it is clear that the weight of the comb of the onyty group was significantly higher. The difference was 43.6%.

crest mass compared to control. 5 The proposed method of increasing the fertility of animals in comparison with the known ones also has the following advantages. First, the beats are produced dry, therefore it is convenient for up to 5 bucks in feed and premixes. Secondly, the production of the preparation of beats is feasible under industrial conditions. , 10 The formula of isorethorgy 1. A method of increasing the fertility of animals, including the introduction of hormonal substances possessing 646 30 6, characterized in that, in order to increase the efficiency of the method, Bitris is a product of vital activity of Blakeslea fungus trispora. 2. A method according to claim 1, characterized in that the bitris preparation is administered with animal feed prior to mating, during mating and before delivery at a dose of 50-100 mg per 1 kg of live weight.
