Abstract :
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
