The crossbreeding argument has been running for decades. A Holstein cross gives more milk on paper. A Sahiwal survives the summer, walks further, gets sick less, and calves without help.
What people report in practice:
- Crosses need better feed, better shade and better management, and they punish you for all three
- Heat stress cuts a cross's yield hard in June and July, which is exactly when milk is worth most
- Sahiwal and Cholistani yields are lower but far steadier, and the vet bill is smaller
- Buffalo is a different calculation again, because the fat content changes what you are paid
If you are running a herd, small or large: which animals, what daily yield, what you spend on feed and medicine, and whether you would buy the same again. Numbers rather than opinions, if you have them.
