A comparative study of thephysicalandchemicalpropertiesofbuffaloand goat milk and theireffectonthe levelofcalciumandphosphorusof femaleratstreatedwithphosphoricacid

Abstract

The current study included estimating, comparing the physical and chemical properties of buffalo and goat milk, and noting their influence in some of the biochemical parameters in the blood serum of laboratory rats' females those treated with phosphoric acid. This study was conducted on a herd of buffalo and another of goat in Dhi-Qarprovince-south of Iraq.The results of physical and chemical tests for buffalo and goat milk showed a significant increase in (pH) values of goat milk compared with (pH) values of buffalo milk, while these results showed significant increase in the values of the specific weight, the percentage of fat, percentage of lactose and percentage of ash content for buffalo milk compared with goat milk. We observed insignificant increase in the percentage of total acidity, freezing point and the percentage of protein for buffalo milk compared with goat milk. Also this studyshowed that treatment of female rats with phosphoric acid (second group) caused a significant decrease in the calcium level compared with the control group (first group).The results showed significant decrease in the phosphorus level for the groups third (buffalo milk group) and sixth (phosphoric acid + goat milk group) compared with the first group, while our results showed significant increase in the calcium level for the groups third (buffalo milk group), fourth (goat milk group) and fifth(phosphoric acid + buffalo milk group) compared with the first group andincrease significantly in the phosphorus level for the second group compared with the first group.
