Biodversification of calcium from feed to milk in does kept under buffer feed technology

Twenty four lactating Barbari does were divided into six groups on the basis of their phenotypic features and potential of production. One animal from each group was randomly allotted to one of the four treatments i.e. A, B, C and D. Buffers viz. sodium bicarbonate and magnesium oxide in combination were offered at the rate of 0.00 and 0.00, 0.50 and 0.25, 1.00 and 0.50 and 1.50 and 0.75 per cent of assumed dry matter intake to be 4 per cent of live weight, respectively. In addition each animal also got 200 g concentrate (Gram chuni) and ad-lib leguminous straw (Cajanus cajan). The metabolism and milk production trials were conducted after 21 and 30 days of start of the experiment, respectively. Findings revealed that biodiversification of calcium from feed to milk and to body storage increased and to faeces decreased whereas to urine it remained unchanged with the increasing dose of buffers.
