RU2258498C2 - Method for stimulating reproductive function in sows - Google Patents

Abstract

FIELD: veterinary science, swine breeding.

SUBSTANCE: one should affect biologically active centers (BAC) 5, 7, 11, 41, 44 in sows, moreover, this impact should be performed after weaning the piglets with the help of fixed metal balls due to pressing technique per 1.5-2 min daily for 10 d, after that they should be removed.

EFFECT: higher efficiency of stimulation.

Description

The invention relates to animal husbandry, in particular to pig farming, and can be used to stimulate the reproductive function of sows.

Known methods of stimulating the reproductive function of sows, including the use of male pheromones [2], hormones, immune sera, antibiotics, tissue stimulants [1], the introduction of antioxidants in the diet [1, 2].

The disadvantages of these methods include:

- the high cost of drugs;

- the availability of laboratory equipment;

- the complexity of the application.

The closest analogue to the proposed method is a method of stimulating the reproductive function of animals, which consists in exposure to biologically active centers (BAC) of the body by cryopuncture [3].

The disadvantages of this method are:

- the need to use special protective clothing;

- the need to use expensive equipment and the high cost of its maintenance;

- insufficient effect of stimulation of reproductive function.

The objective of the proposed method is to eliminate the need to use special protective clothing, expensive equipment and the cost of its maintenance, and to increase the efficiency of stimulation of the reproductive function of animals, in particular sows.

The problem is solved due to the fact that in the known method of stimulating the reproductive function of animals, which consists in cryopuncture effects on biologically active centers, according to the invention, the stimulation of the reproductive function of animals, in particular sows, is carried out by daily pressing on metal balls fixed with adhesive plaster with a diameter of 2-2.5 cm to biologically active centers No. 5, No. 7, No. 11, No. 41, No. 44 for 1.5-2 minutes within 10 days after weaning of piglets.

To clarify the essence of the proposed method presents a drawing of a sow.

The presented figure shows biologically active centers:

No. 5 - on the dorso-medial line of the body between the 1st and 2nd spinous processes of the lumbar vertebrae;

No. 7 - on the dorso-medial line of the body in the recess between the spinous process of the last lumbar vertebra and the first sacral vertebra;

No. 11 - on the dorso-medial line of the body in the recess between the 2nd immobile and 3rd movable caudal vertebrae;

No. 41 - on the medial line of the body at a distance of one width of the palm and two widths of the fingers under the vulva;

No. 44 - three fingers across below the lower edge of the patella, lateral by one transverse finger from the scallop of the tibia.

In the experiments, we used two groups of sows of large white breed aged 3-5 years with an average live weight of 190-220 kg, five goals in each group.

Example. The sow was 4 years old and had a live weight of 200 kg. Measured the level of bioelectric potential of BAC No. 5, No. 7, No. 11, No. 41, No. 44. At the beginning of the experiment, each metal ball with a diameter of 2-2.5 cm was glued to a thin adhesive plaster measuring 5x5 cm and applied to the center. Next, daily stimulation of BAC No. 5, No. 7, No. 11, No. 41, No. 44 of sows by pressing the fixed balls for 1.5-2 minutes for 10 days after weaning was performed. After that, the balls were removed and the level of bioelectric potential of the treated centers was measured. With an average biopotential of 40.4 μA or more, an increase in the reproductive ability of sows is established (table 1).

To measure the biopotential of the BAC of sows, any instrument designed to conduct electroacupuncture or to take biopotentials of the BAC of human and animal skin can be used.

Thus, the BAC stimulation method No. 5, No. 7, No. 11, No. 41, No. 44 of sows using fixed metal balls makes it possible to reduce the time of arrival of uterus to hunt by an average of 2.4 days and increase the percentage of fertility from first insemination by an average of 20%. The proposed method eliminates the need to use special protective clothing, expensive equipment and the cost of its maintenance, reduce the time of sows coming to the hunt and increase fertility from the first insemination.
