A cross-bred cow gives litres of milk a day for days after she calves. The dairy pays rupees for each litre. How much milk does she give in one lactation, and how much is it worth?
Need a reminder? The key ideaShow
Animal husbandry is the scientific management of livestock. Milch animals give milk and draught animals do farm work; the cow is Bos indicus and the buffalo is Bos bubalis. The milk in one lactation is the milk of a day times the days. Exotic breeds give a long lactation; local breeds resist disease.

Step 1. The milk. litres.
Step 2. The money. rupees.
Answer: litres, worth rupees.
