Decrease in pig fertility as a result of reciprocal translocations and associated economic effects on the basis of rcp(7;13)(q13;q46)
Languages of publication
Reciprocal translocations, very frequently identified in pigs, are the cause of fertitlity decrease. The aim of this work was to provide an objective assessment of the real effect of reciprocal translocation (7;13) on the fertility of carriers and associated economic effects. The experiment has shown that fertility, expressed as a mean litter size, decreased by 48% in comparison to that of the control group. On the basis of simulation account, financial losses incurred a translocation as a result of using carrying boar in a commercial herd were estimated at about 8,000 USD for natural mating and at about 162,000 USD for artificial insemination. The results obtained show the need for introducing a system for cytogenetic control of boars producing small litters into the Polish swine improvement programme.
