ABSTRACT

Milk samples pertaining to first to fifth lactation from 120 native cows belonging to three districts
of Assam, (India) were utilized to study the effect of location, lactation order and stage of lactation
on certain physio-chemical traits of milk. The least squares mean for specific gravity, fat per cent,
solids-not fat per cent, total solids per cent, protein per cent and pH in the milk of native cattle of
Assam were found to be 1.027±0.0003, 5.341±0.067, 8.544±0.035, 13.885±0.07, 3.047±0.036
and 6.745±0.012 respectively. Location showed highly significant effect on fat, solids-not fat, total
solids and protein per cent except on specific gravity and pH of milk. Order of lactation had nonsignificant
effect on all the milk constituents under study. However, stage of lactation showed highly
significant effect on fat, solids-not fat and total solids percentage and non-significant effect on
specific gravity, protein content and pH in milk.
