Abstract

Spectroscopic predictions can be used for the genetic improvement of meat quality traits in cattle. No information is however available on the genetics of meat absorbance spectra. This research investigated the phenotypic variation and the heritability of meat absorbance spectra at individual wavelengths in the ultraviolet-visible and near-infrared region (UV-Vis-NIR) obtained with portable spectrometers. Five spectra per instrument were taken on the ribeye surface of 1185 Piemontese young bulls from 93 farms (13,182 Herd-Book pedigree relatives). Linear animal model analyses of 1481 single-wavelengths from UV-Vis-NIRS and 125 from Micro-NIRS were carried out separately. In the overlapping regions, the proportions of phenotypic variance explained by batch/date of slaughter (14 +/- 6% and 17 +/- 7%,), rearing farm (6 +/- 2% and 5 +/- 3%), and the residual variances (72 +/- 10% and 72 +/- 5%) were similar for the UV-Vis-NIRS and Micro-NIRS, but additive genetics (7 +/- 2% and 4 +/- 2%) and heritability (8.3 +/- 2.3% vs 5.1 +/- 0.6%) were greater with the Micro-NIRS. Heritability was much greater for the visible fraction (25.2 +/- 11.4%), especially the violet, blue and green colors, than for the NIR fraction (5.0 +/- 8.0%). These results allow a better understanding of the possibility of using the absorbance of visible and infrared wavelengths correlated with meat quality traits for the genetic improvement in beef cattle.
