Implementation of selection for carcass quality in a pig breeding program in the Netherlands1
نویسنده
چکیده
In North America and in Western Europe the valuation of pork is changing from input driven towards output directed. It is changing from selling the products of slaughtered pigs towards producing the pigs for which a clear market exists. Two discussions are underway; one is about specifications and value of pork products and the other one on classification systems. These classification systems try to estimate the quantity and quality of the products in the earliest possible stage, at the very moment the pig is killed. Known and used systems are the Hennessy Grading Probe (HGP) and AutoFOM.

In this study, selection strategies were simulated to find optimal selection strategy in Japanese quails. Breeding goal was consisted of body weight and egg weight traits. Effects of using genetic markers related to carcass weight were investigated by five different selection strategies. In this case, breeding goal included body weight, egg weight and carcass weight. Deterministic simulation, b...

متن کاملGenomic selection in a pig population including information from slaughtered full sibs of boars within a sib-testing program.
Genomic selection is becoming a common practise in dairy cattle, but only few works have studied its introduction in pig selection programs. Results described for this species are highly dependent on the considered traits and the specific population structure. This paper aims to simulate the impact of genomic selection in a pig population with a training cohort of performance-tested and slaught...
متن کاملValidation of the QTL on SSC4 for meat and carcass quality traits in a commercial crossbred pig population.
Porcine chromosome 4 harbours many quantitative trait loci (QTL) affecting meat quality, fatness and carcass composition traits, detected in resource pig populations previously. However, prior to selection in commercial breeds, QTL identified in an intercross between divergent breeds require confirmation, so that they can be segregated. Consequently, the objective of this study was to validate ...
متن کاملFrom phenotyping towards breeding strategies: using in vivo indicator traits and genetic markers to improve meat quality in an endangered pig breed.
In endangered and local pig breeds of small population sizes, production has to focus on alternative niche markets with an emphasis on specific product and meat quality traits to achieve economic competiveness. For designing breeding strategies on meat quality, an adequate performance testing scheme focussing on phenotyped selection candidates is required. For the endangered German pig breed 'B...
