چکیده
|
A total of 45 samples of goats milk were collected during the milk production season to estimate %protein by kjeldahl method and also as much as formol number. all samples were analyzed and correlation coefficient between the results was calculated to get a constant factor from which we can estimate protein content by formol titration method directly. the calculated factor was 2.505 and the suggested concluded equation for protein determination was as follows: protein content (%) = 2.505 x formol no – 0.114. however, the differences when applying such equation and kjeldahl method were statistically insignificant. protein content (%) by kjeldahl method (a) differed significantly from that given by milkoscan method (b) as shown in the following equation: a = 1.2008 x b – 0.4428
