PLANNING DECISIONS OF RECONSTRUCTION WORK IN PIG REPRODUCTION USING ARTIFICIAL INSEMINATION

Abstract

Commodity production of pork in GO «GF «Gontarivka» IT NAAS» was based on the use of four premises using a flow system with uneven groups each year. Using current technology, the production cycle was 5.5 to 9.5 months (average sow farrowing ranges 1.26-2.18 per year): four months of idle and growing periods and one and a half months of suckling period. This approach to the reproduction of livestock has led to overconsumption of feed for breeding stock, problems with the reproductive system in some animals and an increase in the total production cost. To improve the system of pig reproduction, the farm has formulated a step-by-step introduction of pig reproduction technology based on artificial insemination. Volume-planning solutions for the reconstruction of the farm have been developed, which provide for partial re-planning of the premises for reproduction of livestock, keeping boars, conditionally pregnant pigs and sows, and artificial insemination, to transfer to flow technology with uniform groups throughout the year. Reconstruction of the premises for the reproduction of livestock was carried out by organization of an arena and a laboratory for artificial insemination, the installation of individual machines for insemination of sows. The proposed reconstruction scheme provides for the maintenance of 99 single and pregnant sows in group machines, 30 sows in individual insemination machines, 14 breeding boars and up to 15 boars. The laboratory of the artificial insemination point provides the artificial insemination technician with operations on sperm quality assessment, preparation of media, dilution, assessment and storage of sperm, maintenance and storage of documentation, etc. The work of the artificial insemination point in Gontarivka IT NAAS was carried out in several stages.
