Abstract

Cheese was made from individual milk samples taken from six buffaloes on
day 50 post-partum just before the start of their treatment with bOvine somatotrorpin
bst (control) and on day 70 after they received two bi-weekly injections of bst to study
the effect of bst treatment on milk composition and manufacturing properties,
chemical composition and organoleptic properties of soft cheese.
Cheese samples were stored at4·C for 4 weeks and analyzed as fresh and
after 4 week storage period .Results indicated that the use of bst did not affect milk
compoSition, or its manufacturing properties in terms of rennet coagulation time
(RCT), curdling time (CT), cheese yield and fat loss in whey. Also the use of bst did
not influence cheese composition and did n otl nterlere with ripening indices of the
manufactured soft cheese .Furthermore, the results showed that the use of milk from
buffaloes supplemented with bst did not nip-up the organoleptic properties of soft
cheese.
