The livestock sector is positioned to be a major growth area. The livestock sector is socially and economically very significant in the country due to the multi-functionality of livestock performing output, input, asset and socio-cultural function. It is increasingly recognized that dairying could play a more constructive role in promoting rural welfare and reducing poverty. Buffalo dung is an important input as organic fertilizer for crop production and also widely used as fuel in rural areas. Buffalo also serves as an insurance cover for the poor households being sold during times of distress. Implementation of dairy development programmes and improvement of dairy farming technologies have increased milk production of India from 17 million tonnes in 1950-51 to 210 million tonnes in 2020-21. India ranks first in milk production, accounting for 23.0 per cent of World production. The per capita per day availability of milk has reached 427 grams in 2020-21 (PIV, GOI, 2022). The study was conducted on randomly selected fifty milk producing household in three villages of district Faridabad of Haryana. The highest feed cost was worked out in marginal followed by small and medium herd size groups. The study shows that cost of feed and fodder per milch Buffalo per day was Rs.152.46, Rs.155.37 and Rs. 175.64 in marginal, small and medium herd size groups respectively. The net maintenance cost of per milch buffalo per day was estimated by deducting the income from dung from the total maintenance cost. The net cost of maintenance per milch buffalo per day was Rs. 184.01, 187.61 and 211.14 for marginal, small and medium herd size groups, respectively. The benefit cost ratio per milch buffalo per day was 1.27, 1.42 and 1.43 for medium, small and marginal herd size groups, respectively. The participation of man and women in dairy farming activities indicated that women constituted the dominant workforce engaged in dairy farming. The participation of women in milk production was 87.34 per cent of the total dairy aspects.
