Dairying is also a major source of livelihood for approximately 80 percent of small and marginal farmers in India (typically owning one to three milk-producing animals) who contribute approximately 70 percent to the total milk production. India has the world’s largest livestock population 58 percent of buffaloes and 15 percent of cattle. Owing to this huge bovine stock, though India has managed to attain 1st position in milk production, the full potential of Indian milk herd remains unattained. The milk productivity of India’s livestock is less than half (48%) of the global average: 987 kg per lactation compared to the global average of 2,038 kg per lactation. There is a need to raise the milk yield in order to enhance the per capita availability of milk and to meet the increasing demand. The financial effect of animal health problems is familiar, however, its devastating impact on the income of farmers' and well-being is generally minimized.
