Abstract
266 samples from the herd of college of Agriculture, Duhok University, were analysed during the lactation period. Total solids precentage was 12,26-23,92% with an awerage of 17,29% in morning milk, while in evening milk it was 9,66-24,62% with an average of 17,89%. Total solids percentage inereased at the end of lactation period. Fat percentage was between 2,00 8,00% with an average of 5,59% in morning milk and 3,00-7,80% with an average of 6,15% in evening milk. Lactose percentage was 1,33 8,77% with an average of 4,79% in morning milk and 1,53-6,86% with an average of 4,36% in evening milk. Protein percentage was 1,25- 9,95% with an average of 5,34% in moring milk, in evening milk it was 2,32-9,67% with an average of 5,67%. Non protein nitrogen percentage was 0,026-0,178% with an average of 0,089% in morning milk, in evening milk it was 0,026 0,187% with an average of 0,096%. Ash percentage was 0,30 1,56% with an average of 0,89% in morning milk while in evening milk it was 0,30-1,60% with an average of 0,87%.
