Abstract

FIELD: animal science. SUBSTANCE: the method for stimulating reproductive functions in sows deals with enhancing biologically active centers N 5, 7, 11, 41, 44. Moreover, one should increase biological functions due to removal of one among five biologically active centers combined into single system with the help of atropine solution microinjections, and due to enhancing biological activity of other centers, as well. The suggested method provides higher percentage of conception rate as a result of the first insemination and could be applied for enhancing biological functions in sows. EFFECT: higher efficiency of stimulation. 1 dwg, 2 tbl

Description

 The invention relates to animal husbandry and can be used to stimulate the reproductive function of animals, such as pigs.

 Known methods of stimulating the reproductive function of pigs using specific and nonspecific effects, which include the use of male pheromones, the introduction of antioxidants into the diet, treatment of sows with vitamin preparations, and the use of a test boar [1].

The disadvantages of these methods include:
- the presence of special skills;
- lack of effectiveness;
- high costs for the maintenance of the boar probe.

 The closest analogue to the proposed method is a method of stimulating the reproductive function of animals, which consists in influencing the biologically active centers (BAC) of the body 5, 7, 11, 41, 44 with metal rods 25-30 cm long, 0.5-0.8 cm in diameter, aged 10-15 minutes in liquid nitrogen (cryopuncture) [2].

The disadvantages of this method are:
- the need for highly qualified specialists;
- the need to use protective clothing;
- the need to use expensive equipment and high labor costs for its maintenance.

 The objective of the proposed method is its simplification and cost reduction by eliminating the need to attract highly qualified specialists, the use of protective clothing, expensive equipment and reducing labor costs for its maintenance.

 The problem is solved due to the fact that in the known method of stimulating the reproductive function of animals, in particular pigs, which consists in enhancing biological functions by acting on biologically active centers 5, 7, 11, 41, 44, according to the invention, enhance the biological functions of pigs by the shutdown method by microinjection of an atropine solution of one of the five biologically active centers, combined into a single system, by enhancing the biological activity of other centers.

In the drawing, biologically active centers are shown:
5 - on the dorsomedial line of the body between the 1st and 2nd spinous processes of the lumbar vertebrae;
7 - on the dorsomedial line of the body in the recess between the spinous process of the last lumbar vertebra and the first sacral vertebra;
11 - on the dorsomedial line of the body in the recess between the 2nd immobile and 3rd movable caudal vertebrae;
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;
44 - three diameters of the finger below the lower edge of the patella, lateral to one transverse finger from the scallop of the tibia.

 To develop a method of stimulating the reproductive function of animals, such as pigs, a method is used to measure the level of biopotential in biologically active centers using a milliammeter of an ELAP device. To measure the biopotential of BAC in sows, acupuncture points extrapolated from anatomotopographic localization schemes of acupuncture points intended for the prevention and treatment of obstetric and gynecological diseases of cows are used [2].

 In the experiments we used sows of large white breed at the age of 3-5 years, with a live weight of 120-250 kg.

 For measuring the biopotential of the BAC of sows, any device designed for conducting electroacupuncture or taking readings of the biopotentials of the BAC of human and animal skin can be used.

 Example. The sow had an age of 3 years and a live weight of 185 kg. To stimulate reproductive function, the method of disabling one of the biologically active centers 5, 7, 11, 41, 44 is applied using subcutaneous microinjection of 2 ml of a 0.1% solution of atropine in one of the above centers and subsequent measurement of the bioelectric potential in other centers. With an average biopotential value of 69.3 μA or more, an increase in the biological functions of the sow is established due to the bioenergetic activation of the system of surface-localized biologically active centers (table 1).

 The degree of significance of differences with: ** -P <0.01; *** -P <0.001.

 Thus, the method of disconnecting one of the biologically active centers leads to an increase in the percentage of fertility from the first insemination and can be used to enhance the biological functions of sows. The method allows without the involvement of highly qualified specialists, the use of protective clothing, expensive equipment, while reducing labor costs for its maintenance, to stimulate the reproductive function of sows, and also reduces the time spent on stimulation by 18 minutes (table 2).
