title: [Correlations between certain parameters of weight increase, slaughter performance, meat condition and thyroid function in swine for slaughter comparing various boar offspring].
abstract: Comprehensive tests were applied to a larger number of pigs for slaughter, all kept under the same conditions and all of known genetic origin. Subjects of testing were pork quality parameters, pH45, colour brightness, and drip loss as well as morphological thyroid parameters, epithelial level, nuclear surface, and follicle diameter as well as butanol-extractable iodine in the serum. All parameters were compared with one another, and each of them was then related to net body growth and increase in high-quality pork components. Follicular epithelial level and butanol-extractable iodine were found to be in negative correlation with one another. Higher drip loss was in concomitance with relative morphological thyroid quiescence. Higher net growth was exhibited by animals with portions of high-quality pork components went along with significant deterioration of general pork quality. Six boar progenies were tested for the above parameters. Some of the boar progenies exhibited statistically secured differences with regard to the thyroid parameters, butanol-extractable iodine, and pork quality.
