Way rehabilitation sperm of boars manufacturers

 

(57) Abstract:

The invention relates to veterinary medicine. The method comprises bubbling glucosegalactose-sulfate environment ozone-oxygen mixture with ozone concentration of 5 mg/l within 30 minutes Method causes symptoms in the environment antimicrobial properties. The use of this medium for dilution of sperm manufacturers improve the sanitary quality of sperm and increases fertility after insemination of sows. 1 PL.

The invention relates to veterinary medicine, in particular to the technology of artificial insemination, and can be used for the renovation of the sperm of boars manufacturers.

Known manual method of obtaining semen from boars. Sperm obtained by this method are of high quality and has a low bacterial infection [1].

The disadvantages of the manual method, you should include the fact that it requires from staff great physical stress and overcome the psychological barrier. Increases time spent on obtaining sperm, because the operator is located near each of the boar charge from the beginning to the end of ejaculation.

Known methods of rehabilitation of sperm about what abiotical and sulfonamides, which have bacteriostatic activity against most gram-negative and gram-positive microorganisms [2, 3].

The disadvantages of sanitation preparations should include the fact that they are not effective due to the emergence of resistant strains of pathogenic and conditionally pathogenic microorganisms, creating them impossible to use with low sperm quality and have a high cost.

The proposed method of remediation sperm includes common with the prototype of the sign is the presence in synthetic environments antimicrobial substances. In relation to the prototype characteristic of which is pre-bubbling glucophageglucophage-citrate (GHCS) environment that is used to dilute semen of boars, ozone-oxygen mixture at a concentration of 5 mg/l within 30 minutes.

Preparation of ozonated GHCS environment was passing through it of ozone-oxygen mixture at a concentration of 5 mg/l within 30 minutes. Pre GHCS environment in quantities of 1 liter was poured into plastic bottles of 1.5 litres, closed by a stopper with two holes. through which passed two hoses made of polyurethane. One hose was attached ceramic races who begins exhaust gas.

Microbiological studies revealed that ozonated GHCS environment has a strong bactericidal effect against Staphylococcus aureus, Proteus vulgar, Pseudomonas aeruginosa and Escherichia coli.

When determining the optimal concentration and time of ozonation ozone-oxygen mixture GHCS environment was based on the antimicrobial effect of ozone, its effect on gametes and reproductive quality of sows. The studies found that the optimal concentration is 5 mg/l within 30 minutes.

Research and production experience held on the main sows of large white breed and cross-breed weighing 180-220 kg Animals in the experimental group (n=190) were seminal sperm, diluted ozonized GHCS environment. Dilution was performed fractional: initially half degree and again 10 minutes before insemination to the recommended dilution. Sows of the control group (n=200) were seminal sperm, these same manufacturers, but when diluted ejaculates GHCS environment with poligram. Artificial insemination of sows spent ungraded way, after the establishment of the immobility reflex with a boar is probe, twice, perlocutionary the ability of sperm, the duration of pregnancy, the incidence of sows postpartum endometritis, multiple pregnancy, weight piglets and safety are presented in the table.

As can be seen from the table, fertility, duration of gestation sows was in the experimental and control groups are almost identical, which confirms the evidence that the ozone does not violate the processes of fertilization and pregnancy. When observing animals in the postpartum period, found that the incidence of sows acute postpartum endometritis in the group where sanitation sperm conducted saturated with ozone synthetic environment, which was 4% less than when using antibiotikoterapia drug poligen. The prolificacy of sows had no significant differences, and the number of stillborn piglets was lower in the experimental group was 55.6% compared with control. The live weight of piglets at birth in the group that used ozone-oxygen mixture was higher by 7.7% (P<0,05). The effect of krupnoplodniy affected the viability of the animals in the experimental group the safety of piglets on day 21 was higher by 8%, and the live weight of piglets at 3%.

Direct material costs for the rehabilitation of scooterzone drugs.

Thus, the proposed method of remediation sperm of boars manufacturers ensures the maintenance of high fertility of sows, allows to obtain a large and viable offspring with the lowest material costs.

FIELD: medicine.

SUBSTANCE: method involves using product containing spermatozoa treated by drying with freezing to humidity level of 1% and having injured membrane or spermatozoon head so that spermatozoon nucleus retains its genetic validity enough for fertilization. The spermatozoon heads fertilize an isolated oocyte after rehydration and microinjection being done. The retained genetic integrity is enough for fertilizing an oocyte and producing living descendants. Method involves collecting living mature spermatozoa, making spermatozoa suspension in special purpose physiological medium, freezing the spermatozoa suspension for producing frozen spermatozoa, drying the frozen spermatozoa or spermatozoa heads in vacuum to humidity level of 1%, making rehydration of spermatozoa or spermatozoa heads with injured membrane and selecting those retaining nucleus of genetic integrity. The selected spermatozoa or spermatozoa heads are used for fertilizing isolated oocytes with living descendants being produced.

EFFECT: enhanced effectiveness in producing living descendants.
