Baghabarighat milk shed area (BMSA), a part of Bangladesh Milk Producers Co
-operative Union Limited (BMPCUL), was selected to study the compositional
aspects of milk collected over 6 year period. Average fat, SNF and TS conte
nt of milk were 5.15, 7.82 and 12.97%, respectively, over the year. Higher
yield (thousand 1/day) during January (40.94) and February (41.13) and lowe
r for July (20.47), August (17.84), September (18.59) and October (18.87),
were observed. Intermediate values of production were observed for November
(24.35), December (34.70). March (31.72), April (29.33), May (26.23) and J
une (28.14). There was slight decrease (P >0.01) in fat value in January (5
.02%) and February (4.94%) when the yield was highest. Feed availability in
creases milk yield, live weight gain and dry matter intake of cows. But no
specific changes seemed to have taken place throughout the year for fat, so
lids-not-fat and total solid value. A large variation (P <0.01) was observe
d for the amount of milk collected throughout the year. Mentioned parameter
s were highly correlated either negatively (fat and SNF, fat and milk yield
, SNF and TS and also TS and milk yield) or positively (fat and TS, SNF and
milk yield) all over the year.
