Friends, in the last topic 2.1.1 we had seen many reasons, why we should go for a dairy farm. We have noted that a dairy farm in India not only produces milk & dung & urine, but also Cattle heads too.
Milk, dung& urine can be processed to some extent in farm levelto make them gainful. We will be discussing them later. But what about the heifers, male calves that our farm will produce? Once born the genes will not change. The only option we will have is to provide good nourishment.
Friends! Gene will speak 50% and husbandry will speak 50%. Good & bad characteristics (traits) depend mainly on composition. So we must plan to have calves that have genetic strength most suitable for us. Let us study some good qualities of our proposed farm.
You have to study it and edit column 5 as you like. I will say what I think afterwards.
Please remember Indian cattle are species“Bosindicus” while Holstein & Jersey are quite different, termed “Bostaurus”- So we will call them exotic breeds.

We can guess what threat is there in rearing Exotic animals. Within Indian we prefer GIR. What will you prefer?
