Hossain 112002511Investigation was carried out to determine specific gravity and chemical quality of milk produced by different primary societies of Bangladesh Milk Producers`Cooperative Union Ltd. (Milk Vita). The chemical qualities of milk produced by primary cooperative societies were quite good i.e., fat, SNF and TS content of milk ranged between 4.327 and 4.853, 7.707 and 7.788, 12.03 and 12.62% respectively. Specific gravity and fat content of milk of these societies were within the normal range but the range of SNF content of milk was slightly lower than the normal range. Out of twenty five primary cooperative societies engaged in the supply of milk of different dairy plants of Milk Vita, Bangalpara primary cooperative society was superior (fat 4.853%, SNF 7.766%, TS 12.62% and specific gravity 1.027) than those of other societies.]]>Eckles, C.H., W.B.
