Absorbance Spectra

AbstractSpectroscopic 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.

Different Doses

The article studies the technological grain quality traits of rice varieties of Russian breeding Rapan, Flagman, Olimp, Azov, Patriot in the yield of 2017-2019 grown in the Abinsky district, Krasnodar region. Purpose of the research was to study the effect of doses of nitrogen fertilizers on the technological grain quality traits of rice varieties with a low amylose content. Rice varieties were evaluated by mass of 1000 absolutely dry grains, filminess, vitreousity, and fracture when grown with different doses of nitrogen fertilizers N60, N120. With an increase in the dose of nitrogen to N120, "the mass of 1000 absolutely dry grains", "vitreousity", "fracture" remained unchanged or the "filminess" changed. The pattern of changes in grain quality traits may indicate an intensive type of varieties Rapan and Olimp.

An increase in the doses of nitrogen fertilizers applied during the cultivation of new rice varieties Nautilus and Yakhont in the old-deltoid and valley agrolandscape zones led to significant changes in grain quality traits. The grain size of the varieties grown in the Krasnoarsmeysky district did not change due to the level of nitrogen fertilizers, for those grown in the Abinsky district, decreased by 0.3 g in variety Nautilus and increased in variety Yakhont with increased dose of applied nitrogen. The vitreousity of grain increased in Nautilus in the Krasnoarmeysky district by 2%, in Abinsky - by 7%; in the variety Yakhont - increased by 2% and practically did not change, respectively. A tendency toward a decrease in grain fracture in the Krasnoarmeysky district and an increase in head rice content in the variety Nautilus in the Krasnoarmeysky and Abinsky districts was noted.
