If you are entirely new to largescale dairying, I advsie you to go for 10 animals to startwith. If you are going for a mixed type of dairy farm. then 5 cows and 5 buffaloes would help your learn dairying practically. After two cycles you can increase the number based on your capacity
Yes Dairying is my passion. I work in a reputed corporate but do this as my hobby. I have a 30 animal farm. Its is Guntur district of AP. How ever if you are from TN you can visit some good dairies in Nellore of AP. Visst the website of De-laval its very educative but the stuff they offer is costly. Dairying is profitable if you have some truested manpower with you. Go aehad ans start it in small way. LEarn the intricacies and in 5 years span. you can excel in it. I predict that in the next ten years Dairy business has great future as some social changes are happening in society which are forcing farmers go away from Dairy.
