RAHMANN G & GODINHO D (Ed.) (2012): Tackling the Future Challenges of Organic Animal Husbandry.
Proceedings of the 2 nd OAHC, Hamburg/Trenthorst, Germany, Sep 12-14, 2012
Materials and Methods
The state of West Bengal is divided into six agro-climatic zones. Except from Hilly zone data were
collected from all five zones through semi-structured, pretested interview schedule. Regarding production
data of farms the records of Bull Mother Farms were collected. Production and other data at
farmers’ level were collected by direct interview. The farmers were selected randomly having at
least two graded up or cross bred animals which have completed at least one lactation. For data on
disease occurrence and treatment health card of the animals were checked during interview. All the
data were pulled and analyzed by simple statistical test like mean and percentage etc.
Result and Discussion
Production and reproduction parameters of both graded up Sahiwal and Gir are depicted in table 1
and these are compared with performance of pure Sahiwal and Gir at Bull Mother Farms.

Under Central Herd Registration Scheme, Govt. of India, 1 st Lactation yield of pure Gir was recorded
in village condition as 2215.64 kg. ( Mathur and Khosla, 1994) but the 1 st Lactation yield of
Sahiwal at village level is 1756 ± 47.61 kg ( Raja, 2004). Milk yield of both the breeds both in farm
