Description

The invention relates to agriculture, in particular to a method for the prevention of postpartum complications in recipient cows.

Today, the problem of the occurrence of postpartum complications in cows is acute on almost all farms. According to statistics, more than half of the cows have various complications after childbirth, such as retention of the placenta, endometritis, uterine subinvolution, ovarian dysfunction.

The frequent development of pathologies in cows is explained, among other things, by metabolic disorders in the animal, lack of vitamins, macro- and microelements in the diet of cows during the dry period. Therefore, the study of methods for the prevention of postpartum complications by introducing harmless drugs of natural origin into the diet of animals is an urgent direction for research.

To date, several options are known for the prevention of postpartum complications in cows by introducing drugs based on natural medicinal raw materials into their diet.

A known method of using a mineral and vitamin premix to stabilize the physiological state of cows (RF patent No. 2303367, publ. 27.07.2007) . The premix contains manganese, zinc, copper, phosphorus, vermulite and vitamin A and is formulated for the different lactation phases of dairy cows. The disadvantage of this feed additive is the incorrect consideration of the physiological norms of the need for certain microelements (manganese, zinc). In addition, the food supply for the regions of Russia is not taken into account.

A method for the prevention of postpartum diseases in cows is presented in the RF patent No. 2201221, publ. 03/27/2003 . The method consists in the fact that dry cows twice 40-50 days before calving and one month after the 1st injection are sequentially injected intramuscularly with 10 ml of 0.5% selenium solution with the simultaneous introduction of the P 52-1 premix, sulfur chalk into the diet and kayoda. The disadvantage of the proposed method lies in the difficulty of substantiating the result obtained, since one drug is administered intramuscularly, and the premix is given together with the feed.

The closest analogue is a method for correcting the birth process in cows for the prevention of postpartum complications (RF patent No. 2701561, publ. 09/30/2019) . For cows in the main diet 10 days before calving, pharmaceutical substances are introduced based on the extract of stinging nettle at a dose of 25 g / head per day for 10 days. However, in this method, the calculation of the application rate is carried out by introducing a pure pharmaceutical substance, which complicates the process of mixing with compound feed.

The technical result of the present invention is the enrichment of the diet of recipient cows during the dry period with biologically active substances to prevent postpartum complications in animals and reduce the recovery period of the reproductive system.

The technical result is achieved by the fact that a two-component phytobiotic feed additive based on extracts of medicinal plants Leuzea saphora and stinging nettle is additionally introduced into the main diet of recipient cows during the dry period.

Stinging nettle is rich multivitamin composition contains ascorbic acid, vitamin K, vitamin _B2, pantothenic acid, carotenoids (beta-carotene, xanthophyll, violaxanthin), tannin and protein substances, amino acids and so forth.

The validity of the use of Safflower Leuzea is associated with the phytoecdysteroids present in it - biologically active substances. Ecdysterone and the direct analogs of ecdysteroids are the main active substances with an anabolic effect and are promising for use in agriculture. In addition, Safflower Leuzea contains alkaloids, ascorbic acid, carotene, tannins, resins, gums, ascorbic acid, inulin, organic acids, etc.

The method is carried out as follows.

In recipient cows, a two-component feed additive based on extracts of medicinal plants is additionally introduced into the main diet, 50 g per head per day for 30 days, starting from the first day of transfer to the dry period. In this case, the feed additive is prepared with the following ratio of components:

100 kg of compound feed;

0.5 kg of safflower leuzea;

2.5 kg of stinging nettle.

Execution example

The effectiveness of the method was determined in scientific and industrial experiments in the conditions of the economy of the Kemerovo region.

Healthy recipient cows of the black-and-white breed were selected and divided into 2 groups - experimental and control, 10 cows each. Animals were selected using the analog pair method. When selecting animals, their live weight, breed, calving age, milk yield, milk fat content, physiological state and date of expected calving were taken into account.

The animals of the control group were fed with a basic diet typical for the farm and including plush wheat, sunflower cake, feed yeast, table salt, monocalcium phosphate, vetch haylage, raw potatoes, hay pastes / meadow.

For the animals of the experimental group, for 30 days, starting from the first day of transferring them to the dry period, a two-component phytobiotic feed additive based on extracts of medicinal plants Leuzea saphora and stinging nettle was added to the main diet, 50 g per head per day.

The experiments also took into account the following indicators: the duration of the subsequent stage, the timing of involution of the uterus, the period from calving to the introduction of the embryo (table 1).

Table 1 - Indicators of the postpartum period of recipient cows

Index Experienced
group (n = 10) Control
group (n = 10) Duration of the successive stage, hour 5.30 ± 0.45 ** 8.21 ± 0.33 Postpartum subinvolution of the uterus, goal - 2 Postpartum endometritis, goal - 1 Serous mastitis, goal - 1 Number of animals for embryo transfer, head ten 6

As can be seen from the table, in the experimental group, the duration of the successive stage decreased by 36%. In addition, in the control group, postpartum complications were observed in 4 cows (40%). Out of 10 cows-recipients of the control group, 2 animals after giving birth were diagnosed with uterine subinvolution (20%), 1 cow (10%) - postpartum endometritis, and one animal - serous mastitis (10%).

It is noted that the addition of a phytobiotic feed additive based on 2 medicinal plants to the diet of recipient cows during the dry period reduces the possibility of postpartum complications in cows.

Claims (1)

A method for the prevention of postpartum complications in recipient cows, characterized in that the recipient cows, within 30 days, starting from the first day of their transfer to the dry period, add a two-component phytobiotic feed additive to the main diet based on extracts of medicinal plants Leuzea saphora and stinging nettle by 50 g per head per day.
