Genetic relationships of feed efficiency and growth traits with carcass traits in Japanese Shorthorn cattle

Those with regular feed intake were low, with estimates for genetic correlations relating to feed efficiency traits and average daily gain favorably moderate to high. In addition, we found a high genetic link between RG and DG. Bull calves' backfat thickness revealed positive or no correlation values for feed efficiency and growth characteristics, according to GI and BF, while carcass traits indicated positive or no correlation data. Both feed utilization capability and carcass characteristics can be improved by genetic modification of both feed utilization capability and carcass characteristics, according to our results, which can be achieved by utilizing RG and BF in Japanese Shorthorn cattle.

Estimation of genetic parameters for carcass grading traits, image analysis traits, and monounsaturated fatty acids in Japanese Black cattle from Hyogo Prefecture

In 29,942 Japanese Black cattle from Hyogo Prefecture, genetic parameters for carcass grading characteristics, image processing characteristics, and monounsaturated fatty acid percentages were estimated. Five carcass grading characteristics, two image analysis characteristics, fat area ratio, and fineness index were among the two MUFA attributes investigated, including one measuring in intermuscular fat using near-infrared spectroscopy and the other using gas chromatography, were included in the analysis of intramuscular fat using gas chromatography, five carcass grading characteristics, two image analysis methods, two image analysis characteristics, two image analysis methods, and two MUFA characteristics, five carcass Although the heritability of the NIRS-based intermuscular MUFA was marginally less than that of the GC-based intramuscular MUFA, the genetic correlation between the two methods was as high as 0. 804.
