The study was conducted on the Erbil Dairy Herd of the Erbil city, to evaluate the effect of body condition score of Bokani dairy cow on milk composition. Milk samples were examined weekly for milk yield and milk fat, protein percentage, fat / protein ratio, lactose, solids not fat (SNF) and freezing point for sixty days. Body condition score of individual cows was recorded in a 1-5 scale. Milk samples were collected from individual cow. Samples collected from cows having similar body condition score were mixed together to make composite sample. The results revealed that the body condition score was affected milk yield and fat percentage significantly (P

The study was done to compare Awassi ewes and Holstein cow’s milk in morning and evening period, in a private animal project in Erbil/ Iraq. The physical properties (pH, specific gravity and freezing point °c) of milk samples which recorded insignificant differences between the morning and evening period of Awassi ewes and Holstein cow’s milk, as well as milk has flavor in ewes, while it increased in cow’s milk. The average yield of cows' milk increased in the morning compared to the evening, while the milk yield of ewes showed an insignificant difference between the morning and evening periods. Fat and fat percentage: protein ratio had decreased in the morning milk compared to the evening milk, instead of in cows the morning milk contained high fat (%) and fat: protein ratio compared to the evening, otherwise, Sheep's milk increased the rates of morning milk protein, lactose and SNF compared to the evening milk, there were insignificant differences between cows’ morning and evening milk protein, lactose and SNF percentages. At the animal or species level, sheep's milk outperformed cow's milk in chemical composition.
