IntroductionPrevious studies in our laboratory have reported improvements in carcass characteristics in Korean native (Hanwoo) steers (Sung et al., 2015), meat fatty acid profile, and performance of Holstein steers (Song, et al., 2013; Ghassemi Nejad et al., 2016) receiving chromium methionine (Cr-Met) supplementation. In those studies, 400 ppb/d of Cr-Met supplementation was reported as the optim ...

Dear Assemu Tesfa,Thaks for your comment. More research on gene alteration can provide selective color of Holstein breeds or others. This color manipulate can easily progress through AI and selective color breeding along with other traits in order to maitain the production quality (meat and milk) in such a harsh (cold or hot-humid) environment. Regards,Jalil.
