Y chromosome variants in cattle Bos taurus and Bos indicus [PDF]
Genetics Selection Evolution, 1982 Summary It is shown that comparison of the size of the Y chromosome between individuals may be made as reliably by computation of measurement relative to the X chromosome as by proportionation relative to the genome in the cell. By either method agreement was found with previous studies : first in placing the Y in the size range, for the cattle ...

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle
Advanced Science, EarlyView.This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Domestic cattle (Bos taurus taurus) are motivated to obtain forage and demonstrate contrafreeloading
PLoS ONE, 2018 Domestic cattle (Bos taurus taurus) are adapted to digest high-roughage diets, but in confinement they are commonly fed low-roughage, high-energy diets. This practice may leave cattle with an unfulfilled need to consume forage.
