Abstract
This study was conducted on 35 Shami goat milk samples taken periodically from Karahta center for Shami goats breeding during lactation period in 2015 (from March to July) at a rate of (3 samples) in a month. Automated Ecremeuse was used to separate cream fats. The results of physico – chemical tests for Shami goats milk fat showed that there were no significant differences at P≤ 0.01 in the means value of pH degree, Saponification number, iodine number, relative density and frezing point during the lactation. However, there was a significant diferences at P≤ 0.01 in the refractive index only. The triglycerides results showed no signifiant differences at P≤ 0.01 in means of concentrations of TAG during the lactation and the TAG contents increased with carbon atoms number reached to maximum level of 13% of total TAG for each of C38, C40, and C42. Beyond this point, the TAG of goat milk decreased with the carbon atoms number and reached to the lowest value for C54 at 2%. This gave the fat of goat’s milk distinctive genetic fingerprint for other species.
