“…Proper selection of gilts and breeding boars provides better results and decreases reproductive disorders such as: (ovulation disorders, embryo resorption, cysts on ovaries, spermatogenesis disorders). Size of litter is also highly dependent on the genetic properties of boars and gilts (2), while new technological achievements enable harmonization of paragenetic factors during upbringing and nursing of sucklingpigs, in nutrition and zootehnical solutions, but also render suckling period shorter and provide maximum usage of all genetic potentials in hog raising production. Appropriate feeding of all categories of hogs represents the most important paragenetic factor (3).…”

Macedonian Veterinary ReviewCritical indicators of intensive production in hog raising are continuity of production, high level of produced series-tours, application of the most contemporary technological achievements without any turnover of capital, high merchandise turnover, and intensive usage of the reproduction potential of breeding material. Production of piglets represents one of the most essential phases in the production of pork meat. In spite of genetic factors, duration of interval wean-conception is one of the basic factors in determination of bringing forth indexes and number of piglets per litter. In order to recognize production costs of piglets completely we found nutrition costs for piglets and sows represent 61%, while other costs such as personal incomes, veterinary services, water, energy, losses, and amortization represent 39% of total costs. On the basis of cost price per feeding day of a sow and the number of piglets per litter, production costs of piglets older than 28 days with an average body weight of 7 kg were determined. Price cost per piglet after weaning, with 7 kg average body weight, and 146 days of reproduction process accounts for 21,78 EUR if there are 10 piglets in a litter. If the reproductive cycle would last exactly the same and if successful conception would be achieved 25 days after weaning, production cost per piglet would be 23,79 EUR.

Searching for the associations between the gene polymorphism and the reproductive traits is essential in defining the genetic native breed specificity, which distinguishes them from the other breeds. The aim of our study was to determine the associations between mutations in the PRL, PRLR, PTGS2, FUT1 genes and sexual and periparturient activity in native Pulawska gilts. The analysis included 72 animals which gave birth to the first litter. Evaluation of the productive value of gilts accounted for indicators of sexual and periparturient activity as well as reproductive traits. The biological material for molecular analyses was obtained from the hair roots of the gilts. The genotype was verified by PCR RFLP analysis. The primers and PCR conditions were determined on the basis of available literature data. Statistically significant differences (P≤0.05) were found at the PRL locus: gilts of AA genotypes (Ins/Ins) at the PRL locus were characterised by longest farrowing duration compared to gilts of AB genotype (P≤0.05). The analysis of PRLR gene showed that gilts of TT genotype revealed a tendency for later occurrence of estrus signs (first and second estrus) and for the markedly longest farrowings (P≤0.05). With regard to PTGS2 and FUT1 loci, no significant differences were found in the parameters of sexual and periparturient activity of the gilts. However, gilts of FUT1 GG genotype gave birth to and reared the largest first litters (P≤0.05). The results of the studies expand the knowledge about the genetic structure and productivity of Pulawska gilts.
