Although european breeds tend to produce more quantity, the quality of Bos Indicus breeds is superior. Fixation of DGAT1 A was found in some Bos taurus breeds and fixation of DGAT1 K in one Bos indicus breed. In Bos taurus cattle, the mounted female is more likely to be in estrus than the mountee, particularly if she exhibits immobility (Baker and Seidel, 1985), whereas social status of Bos indicus females can influence an individual’s chances of being ridden by another female (Mukasa-Mugerwa, 1989; Orihuela et al., 1988). Milk quality. DEHORNING of GAUS - scientifically ADHARMIC. A study has been made of the performance of crosses and backcrosses of Bos taurus and Bos indicus cattle using records covering a period of 15 years from the Experimental Station, Tanga. Calculating pairwise F ST values for pooled subpopulations showed least divergence for Bos indicus breeds with high milk fat percentage.

It is no longer a niche market as evidenced by the recent decisions by some of the world’s leading global dairy companies to develop A2 options as a broader dairy category. Everyone should be cautious regarding quality of milk rather than quantity. Phenotypic and genetic parameters for milk yield in traditional Nublang cattle ("Bos indicus") of Bhutan.
