Question Question 1
Which method is commonly used for improving cattle breeds and why?
Cross breeding of exotic breeds with indigenous breeds is the method commonly used for improving cattle breeds. Exotic or foreign breeds (for example, Jersey, Brown Swiss) are selected for long lactation periods, while local breeds (for example, Red Sindhi, Sahiwal) show excellent resistance to diseases. The two can be cross-bred to get animals with both the desired qualities.
