Description

on average, it took less repeated insemination. Experimental cows showed the weight hunt, however, the average number of repetitions (multiplicity) of insemination was more

control group. Summary data on the results of insemination (in the experiment and after three months after the experiments) and the succession of pregnancy in cows are given in Table. one.

T a b l II c a 1

The enrichment of compound feeds for dairy cows 5 with compound I contributes to a significant reduction in the rate of artificial insemination of cows and a decrease in artificial expenses.

Thorough insemination of cows. Compound I contributes to increasing the fat content of milk.

The change in milk fat in cows by groups, on average, is shown in Table. 2

Table 2

The content of vitamin A and carotene in milk by groups of milk cows is shown in Table. 3

Table 3

An increase in the content of vitamin A and its provitamin (carotene) is of great importance in justifying the nutrition of the population.

Example 2. The effect of feeding enriched for the mixed feed of netel m.

The experiments were carried out on three groups of heifers of the Latvian brown breed, equiped according to the principle of the analogue of 15 animals each. The heifers of the control group received feed ration without compound I in the ration, 75 g / t for the second group and 150 g / t of compound I for the third group were injected.

The experiments lasted 91 days. The test hens will return 20-24 months.

Feed costs for the entire experimental period per animal amounted to 738.7 kg of feed.

Example 3. Additions of compound I to compound feeds for breeding heifers.

The experiment was conducted on three groups of heifers of the Latvian brown breed of 15 animals each, made up of analogues according to the principle of development.

The heifers of the control group received compound feed without compound I. 75 g / t was added to the second group and 150 g / t of compound I for the third group. Duration of the experiment was 91 depy. The age of heifers at the beginning of the experience is 15–18 months.

During the experimental period, each chick consumed on average the desired amount of feed.

kg: 300 150 15.5

units, 96.25 kg of digestible protein, 86.80 kg of sugars and 131.14 g of kari.in.

Costs of carotene per 1 kg of weight gain in the control heifers were 2.46 g, in the heifers of the second group only 2.02 g and in the heifers of the third group 1.94 g, which accounted for only 82.1 and 78.9% of the costs of carotene in the heifers of the control group.

In the heifers of the experimental groups, there was also a reduction in the cost of feed units, digestible protein and sucrose.

The hunt was shown by all heifers, however, the number of pregnant cows after the end of the experiment was significantly different in groups.

The results of artificial insemination of heifers (during the period of experiments and three months after the experiments) are presented in Table. five.

Compound 1 has a positive effect on normalizing pregnant heifers, significantly increasing the percentage of effective insemination of heifers and the percentage reduction of repeated artificial insemination.
