Colostrum of cows of the Sahiwal breed was preserved for I month at 28°C by 5 different methods viz, treatment with.
formaldehyde at levels of 0.1% and 0.05%; acidification with formic acid at levels of 0.5% and 0.1%; and an untreated
control. Weekly aliquots were analyzed for total solids, crude protein. lactose, pH and titratable acidity. Nonprotein
; i) ~ J nitrogen determination was carried out every 2 weeks. There was no SIgnificant change in crude protein and total solids,
content of the colostrums in all the treatment methods. Non-protein nitrogen increased significantly in all treatment C
, groups with the highest increases being recorded in the naturally fermented and the formic acid-treated colostrum batches. '
The pH decreased and titratable acidity increased most rapidly in the untreated colostrum an" least of all in the formaldehyde-:
treated colostrum, Decrease of lactose was most pronounced in the untreated colostrum.
