a) Quality of breeds
b) Breeds having high yielding potential
c) Resistance to diseases
d) Number of cows
View Answer
Explanation: Milk yield is primarily dependent upon the quality of breeds in the farm. Selection of good breeds having high yielding potential (under the climatic conditions of the area) combined with resistance to diseases is very important.
10. Which of the following has to be done in order to realise the yielding potential?
a) Cattle should be left on their own
b) Cattle should be well looked after
c) Cattle should be fed every alternate day
d) Quantity of fodder should be unlimited
View Answer
Explanation: For the yield potential to be realised, the cattle have to be well looked after-they have to be housed well, should have adequate water and be maintained disease-free. The feeding of the cattle should be carried in a scientific manner- with special emphasis on the quality and quantity of fodder.
11. Which of the following is not a stringent measure to ensure proper yield in a dairy farm?
a) Stringent cleanliness
b) Hygiene while storing milk products
c) Hygiene while transporting milk products
d) Ensuring that cattle get enough freedom to perform their daily activities
