All the following are objectives of dairy farm management, except 
1. Improvement in quality of milk
2. Selection of good breeds having high yielding potential
3. Selection of breeds which are vulnerable to diseases
4. Maintenance of quality and quantity of fodder

In dairy farm management, we deal with processes and systems that increase yield and improve quality of milk. Which of the following statement is incorrect in this regard ?
1. Milk yield is primarily dependent on the quality of milk, therefore selection of high yielding breed is very important
