Abstract

In industrial pig breeding, when raising pigs for fattening for the production of meat from racial hybrids of pigs, the most common pattern used for crossing are triangular hybrids of pigs. (during which the breeding process involves three races Jokshir x Landry = F1 - JL ♀ x Durak - D or Pietren - ♂). The obtained selection criteria from the mother are different from those of the father-terminal. Here the mother's hysteresis is maximally expressed, and a high selective differential is achieved on the father side. They are characterized by numerous offspring, mothers have quite a lot of milk, and the offspring in the item is equal. The purpose of the research is to determine how the genetic potential for meat production is fulfilled in the triage pig hybrid, reared for fattening (Yoxhir x Landrand = F1-YLGuyDurak-D), compared to the achieved productive genetic potential of meat in this hybrid, obtained by application of intensive technology on the farm of the Agricultural Cooperative Edinstvo in the village Chelopek in the municipality of Tetovo, Republic of Macedonia, in the production years 2016 and 2017. The research was conducted on a representative sample of 50 heads. From the obtained results in the production year 2016, it is concluded that the genetic potential is 112.2 kg, while the achieved genetic potential for the tested sample is 97.51 kg. The deviation from the genetic potential for meat production is 13.69 kg with the variation coefficient (VC%) of 12.31%. While for the production year 2017, it is concluded that the genetic potential is 113.96 kg, while the achieved genetic potential for the tested sample is 100.95 kg. The deviation from the genetic potential for meat production is 13.01 kg or the variation coefficient (VC%) is 11.42%. This means that if we compare the results obtained in the two years of the study, this year we can conclude that there is a genetic improvement in the weight of the pigs in the examined sample. The obtained average results for the two production years 2016/2017 show that the genetic potential is 112.58 kg, while the achieved genetic potential for the tested sample is 99.23 kg. The deviation from the genetic potential for meat production is 13.35 kg or the variation coefficient (VC%) is 11.86%. From the obtained results we can conclude that the retention from the genetic potential for meat production in this pig hybrid is relatively, because the production is organized in conditions of intensive cultivation technology.
