    ABSTRACT : An investigation was carried out to study the socio economic conditions, milking management practices and quality of milk with 120 milk producers in rural and urban areas of YSR Kadapa district in Andhra Pradesh. Majority of respondents rearing crossbred cows (75.00%) and buffaloes (58.33%) belonged to male groups involving in dairy activities. Majority of the crossbred cow farmers (43.33%) had the education up to high school level whereas in buffalo farmers majority (41.66%) was illiterate in the entire study area. Dairying was the main occupation after agriculture for 40.00 per cent of crossbred cattle and 33.33 per cent of buffalo milk respondents. Maximum percentage of farmers belonged to medium size family (4–6 members) with nuclear family type in both crossbred cow and buffalo milk respondents. Majority belonged to landless category (43.33%) in crossbred cow farmers whereas in buffalo milk respondents, majority belonged to 2-5 acres land holding category. In the selected area of study, majority (55.00%) of crossbred cow farmers had extension contact with veterinarians as against majority of (56.67%) of buffalo farmers had extension contact with para veterinarians. In both crossbred cow and buffalo milk respondents, majority of farmers had no exposure to any type of mass media related to animal husbandry activities. Majority of crossbred cow (96.67%) and buffalo (93.33%) farmers practiced wet hand milking in the study area. None of the crossbred cow and buffalo farmers practiced machine method of milking. Maximum number of crossbred cow and buffalo respondents adopted knuckling method of milking at starting of milking operations followed by stripping at the end of milking. Minimum per cent of respondents among crossbreds (13.33%) and buffalo milk producers (11.67) adopted full hand method of milking in the study area. None of the respondents practiced dipping of teats in antiseptic solution. After milking the usual practice of straining of milk with muslin cloth was not followed by majority of milk producers while cleaning of milk utensils was done with disinfectant by majority of the crossbred and buffalo milk producers. Before milking of animals, washing of hands with water was practiced by majority of milk producers in the study area. Most of the crossbred cow (90.00%) and buffalo (75.00 %) farmers were cleaning the udder alone. Majority of the crossbred cow (70.00%) farmers and 46.67 per cent of buffalo farmers were using pucca flooring in the animal houses. More than 50.00 per cent of the farmers were cleaning the animal sheds twice daily. The quality of milk was analyzed by chemical composition of milk with Lactan 1 – 4 milk Analyzer and somatic cell counts with Delaval Somatic cell counter. The pooled averages of Fat, SNF, Protein per cent along with SCC (x103/ml) of the crossbred cow milk in the study area were 3.61 ± 0.09, 8.20 ± 0.04, 3.41 ± 0.06 and 473.65 ± 94.58.The pooled averages of Fat, SNF, Protein per cent and SCC (x103) of buffalo milk in the entire study area were 7.07 ± 0.21, 9.19 ± 0.10, 3.78 ± 0.05 and 167.68 ± 28.80, respectively. The Protein per cent of crossbred cow milk in rural areas showed a significant variation (P<0.05) with that of urban areas. In rural areas, there was a significant (P<0.05) negative correlation found between SCC and protein per cent in crossbred cow milk. In buffaloes, Fat per cent, SNF per cent and Protein per cent of urban areas varied significantly (P<0.05) with that of rural areas. Somatic cell counts did not differ significantly with parity in both crossbred cows and buffaloes but differ significantly (P>0.01) with stage of lactation in crossbred cows and buffaloes. Method of milking practices have shown a significant variation (P<0.01) on the mean SCC in both cows and buffaloes. In case of crossbred cows hygiene of milkmen, floor type and cleanliness of animal sheds significantly (P<0.05) influenced the somatic cell counts whereas in buffaloes floor type alone significantly (P<0.05) influenced the SCC.
