The correct answer is: All of the above.
Limited availability of quality feed is a major challenge to livestock development in Manipur. The state has a high population density and limited land resources, which makes it difficult to produce enough high-quality feed for livestock. This can lead to malnutrition in livestock, which can reduce their productivity and make them more susceptible to disease.
Prevalence of diseases is another major challenge to livestock development in Manipur. The state has a tropical climate, which is ideal for the spread of diseases such as foot-and-mouth disease and brucellosis. These diseases can cause serious losses to livestock farmers, and can also have a negative impact on the health of humans who consume infected meat.
Lack of access to markets is a third major challenge to livestock development in Manipur. The state is landlocked and has poor infrastructure, which makes it difficult to transport livestock and livestock products to markets. This can reduce the prices that farmers receive for their products, and can also make it difficult for them to access essential inputs such as veterinary care and feed.
In order to address these challenges, the government of Manipur has implemented a number of initiatives, such as providing subsidies for quality feed, improving veterinary services, and developing new markets for livestock products. However, more needs to be done to support livestock development in the state.
