The correct answer is: All of the above.
Low milk yields: The average milk yield per cow in Manipur is only 1,500 liters per year, which is much lower than the national average of 2,200 liters per year. This is due to a number of factors, including poor nutrition, disease, and lack of management.
Lack of processing facilities: There are only a few small dairy processing plants in Manipur, and they are not able to meet the demand for dairy products. This means that much of the milk produced in the state is either sold fresh or wasted.
Inadequate cold chain infrastructure: The cold chain infrastructure in Manipur is not adequate to support the dairy industry. There are not enough cold storage facilities, and the transportation of milk is often not refrigerated. This leads to a loss of quality and quantity of milk.
These challenges have hampered the development of the dairy industry in Manipur. In order to address these challenges, the government needs to provide support to farmers, invest in processing facilities, and improve the cold chain infrastructure.
