The socio- economic profile of farmers rearing crossbred dairy cattle in Cauvery delta region is presented in Table 1. The majority of farmers (48.89 per cent) in the Cauvery delta region, engaged in rearing crossbred dairy cattle were in the middle age group (36 - 50 years), followed by 38.89 per cent of farmers in the old age group (above 50 years) and only 12.22 per cent farmers were in the young age group (less than 35 years). The findings were in contrast with the study by
Rajeev et al., (2016), which reported that a majority (46.66 per cent) of farmers in the old age group were engaged in animal husbandry practices in Shamli district of Indo-Gangetic Plain zone. Regarding the education status of farmers, nearly 28.89 per cent and 22.22 per cent of dairy farmers had completed their graduation and higher secondary studies respectively. The illiterate among dairy farmers in the present study area is only 03.33 per cent which is in accordance with the study of
Senthilkumar et al., (2005) and
Desai et al., (2012).
Further, in Cauvery delta region, 61.11 per cent and 25.56 per cent of farmers have agriculture and animal husbandry as their main occupation. Similarly, 74.44 per cent and 14.45 per cent farmers have animal husbandry and agriculture as subsidiary occupation. The findings were supported by the observations of
Gopi et al., (2016). The majority of dairy farmers (44.44 per cent) in present study were marginal land holders and only a minimum of 1.11 per cent farmers were landless which is in contrast to the study by
Nisha (1996) in Modakurichi block of Periyar district, Tamil Nadu. The variation in the land holding in Cauvery delta region compared with other findings may be due to the farmers having agriculture as either main or subsidiary occupation in addition to animal husbandry activities. The herd size of animal in the present study is nearly equal in all groups with large (above 10 animals) 35.56 per cent, small (1- 5 animals) 34.44 per cent and medium (6-10 animals) 30.00 per cent.
In this region, 42.22 per cent of farmers have more than 20 years of experience, 38.89 percent have less than 10 years of experience and just 18.89 percent have 11 to 12 years of experience, which is comparable with
Rajadurai et al., (2018), who found that the majority of the farmers (40 per cent) in his study had 20-30 years of experience.
The housing management followed by farmers in Cauvery delta region for their crossbred dairy cattle is summarized in Table 2. In the study, 73.33 per cent of farmers in the Cauvery delta region practice loose type of housing, while the remaining 26.67 per cent use conventional dairy barn type of housing. However, according to the study conducted by
Singh et al., (2015) among dairy farmers in Ranchi district, Jharkhand, a slightly higher proportion (95%) of farmers practice loose type of housing. Most of the farmers (76.67 per cent) rearing crossbred cattle in present study have constructed their animal house adjacent to their home and 74.44 per cent of cattle shed structure is Kutcha type. Similar findings were reported by
Rathore et al., (2010) on housing pattern of crossbred cattle owners in Rajasthan who showed that majority of the farmers (65%) housed their cattle near to their homes and that 86.33 per cent of cattle shed structures in his study were kutcha type, which is slightly higher than the present study.
Most of dairy cattle sheds in the Cauvery delta area were constructed in East-West orientation (70.00 per cent) and the remaining 30 per cent of farmers have built their animal houses in North-South orientation. However, according to
Sinha et al., (2009), 56.6 percent of rural dairy animal houses in the Bareilly region of Uttar Pradesh were oriented in east-west direction. To feed and water their crossbred dairy cattle, the farmers commonly use basket type mangers (64.44%) and basin type waterers (57.78%) in Cauvery delta region. In the study area, the most common roofing pattern adopted by farmers for their cattle sheds is gable type roof (54.45 per cent), followed by lean to type roof (40.00 per cent), Gothic arch roof (3.33 per cent) and monitor type roof (2.22 per cent). However, the percentage of farmers using various roofing structure for their cattle shed were thatched (23.33 per cent), tiled (15.56 per cent), asbestos (27.78 per cent) and galvanized iron sheet (33.33 per cent), respectively which was in contrast to the findings of
Sabapara et al., (2010) among tribal dairy farmers of Gujarat.
Nearly, half of the farmers selected for the study have gravel type (46.66 per cent) of flooring in their cattle shed, followed by stone flooring and cement concrete flooring (26.67 per cent) each. Large number of farmers (74.44 per cent) in the study used to collect dung from their cattle shed twice a day regularly. Most of the farmers (98.89 per cent) store the collected manure in the manure pit and around 84.44 per cent of them utilize the manure for their own farm use. Based on the score on general condition and cleanliness of the dairy cattle shed in Cauvery delta region, the housing condition for animals was fair (score-03) in 61.11 per cent cattle shed, followed by good (score-04) in 21.11 per cent cattle shed, poor (score-2) in 16.67 per cent shed and very good (score-5) in only 1.11 per cent cattle shed.
Pearson’s correlation study of socio- economic status with housing management of dairy farmers in Cauvery delta region is presented in Table 3. The age and experience of farmers had a negative and non-significant relationship with dairy housing structures for animal comfort, adoption of general condition and cleanliness of dairy cattle shed. This may be due to the fact that older people with traditional knowledge were reluctant to take up the newer ideas or changes in housing management system arising to the variation in climatic condition. Education status, land holding and herd size had a positive and significant relationship at 1 per cent level whereas occupation had a positive non-significant relationship with dairy housing infrastructure and adoption of housing management practices. The result shows that educated farmers with animal husbandry as main occupation having more land holding and rearing a greater number of dairy cattle trends to adopt suitable housing management practices to the maximum.
The mean ± SE of microclimate of dairy cattle shed with different roofing structure in Cauvery delta region is given in Table 4. The black globe temperature of thatched (34.17±0.65°C) and tiled (37.87±1.13°C) roof structures in dairy cattle shed differs significantly (P<0.05). The overall mean of black globe temperature recorded inside different dairy cattle shed of Cauvery delta region ranges from 32.82°C to 40.32°C. The mean±SE of temperature humidity index (THI), black globe humidity index (BGHI) and Heat Load Index (HLI) of dairy cattle shed with different roofing structure in Cauvery delta region are presented in Table 5. The higher value of THI was recorded in tiled type cattle shed (83.48±0.41). The overall mean of THI value in dairy cattle shed with different roofing structure is 82.76±0.23 which falls under moderate heat stress condition (THI 79 to 88) as categorized by
Armstrong (1994). In the present study, the lower THI value was noticed in thatched shed (82.06±0.49), which is in accordance with the findings of
Jat et al., (2002).
BGHI and HLI showed significant difference (P<0.05) between thatched cattle shed and tiled shed. The value of BGHI and HLI in thatched shed was 83.52±0.36 and 87.32±1.36 respectively, which is considered to be low among all the other roofing structures. The overall mean HLI value of different types of cattle sheds was 89.34±0.49 which is below the threshold level for
Bos indicus (HLI - 96) and on par with the threshold level for white coat colour (HLI-89) developed by
Gaughan et al., (2008).
