Mr. Amit Kumar Singh deserves congratulation for thinking out of box. His theory is worth for brain storming. Maximizing milk production has always been the concern and we have been discussing traditional methods and management to improve. Photo period is well proved and used in poultry production but at least I never practised and thought of using in animal production. His thought-provoking article will lead us to try this way also.
AMIT KUMAR SINGH
Your analysis is right when you want to maximize the production in good conditions.
3 liters more is observed in herd producing an average of more than 30 liters.
I think you never milk a cow in India (normal situation in India, PHD never feed a cow himself)
average production in India is less than 6 liters/day because of feed (quantity quality), management, disease, reproduction lack, etc.
With good feed and management you can double milk production.
With photoperiod management maxi 0,6 l (10%).
fertil your words are not correct. There are many progressive farmers who may be benefitted with this. There is great lag between poor and good producing cows in India and that too with such a large cattle population. Considering merely average production you become biased. Even if I consider average production also, there are some other articles which you can refer.
