The changes in \u00a0chemical composition and properties physicist – chemical for milk during lactation were turned out to increase the ratio of total solids, fat, protein and lactose in the first month of lactation and then declined slightly in the third month until the end of the lactation stage, The proportion of ash was low in the first month and increace in the other months from the lactation stage. And the \u00a0acidity of Shami goats milk was high and intensity in the early of \u00a0lactation stage.

\nThe composition of Shami goat milk proteins was determined and separated (Casein-serum proteins) using electrophoresis technique, and molecular weights was determined comparing to commercial Marker and milk cow. The \u03b2-casein \u00a0of Shami goat milk was the dominant part of Casein proteins and was the fastest in the deportation, compared with \u03b2-casein \u00a0protein of cow milk and had less molecularly weight 23.900 kDa while 26.600 kDa for cow’s milk, and protein \u03b1s-casein \u00a0of Shami goat milk was faster in deportation as compared with that of milk cow and less molecularly weight (30.200- 32.600 kDa) respectively. \u03b2-lactoglobulin protein formed proportion (44%) of the total serum proteins of Shami goat milk and was deported faster compared with cow milk, and therefore disagreed in molecular weight (18.80- 18.40 kDa), respectively, and \u03b1-lactalbumin deportation did not differ from those of cow milk ( 14.200 kDa ). \u00a0\u00a0\u00a0The amino acids were separated using Amino Acids Analayzer device, \u00a0the effect of milking season on the concentration of each of proteins and amino acids milk was studied.\u00a0 It was found \u00a0high proportionS of \u00a0the total nitrogen and non protein nitrogen and non Casein nitrogen and serum proteins in Shami goat milk compared with cow milk, and high content of essential amino acids (Leucine, lysine, valine and arginine) and non-essential amino acids (glutamat , Brolin and taurine), and did not contain \u00a0the amino acid basic tryptophan, and observed no significant difference between the concentration of amino acids when compared to reference with cow’s milk, the amino acid cystine\u00a0 \u00a0Shami was double amount goat milk compared to cow’s milk, and the effect of milking season in each of the proteins and amino acids for milk was unclear largely due to a combination of other factors, the study confirmed that Shami goat milk was an important source of proteins and acids amino when compared with other types milk .
\n\u00a0\u00a0<\/strong>We separated and identify the composition of \u00a0the triglycerides of \u00a0Shami goat milk fat during lactation by using the device (HPLC), and compared with cow’s milk fat. The triglycerides results showed no signifiant differences at P<\/em>\u2264<\/em> 0.01<\/em> in means of concentrations of TAG during the lactation and the TAG contents increased with carbon atoms number reached to\u00a0 maximum level of 13% of total TAG for each of\u00a0 C38, C40, and C42. Beyond this point, the TAG of goat milk decreased with the carbon atoms number and reached to \u00a0the lowest value for C54 at 2%. This gave the fat of goat’s milk distinctive genetic fingerprint for other species. \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 Further were the composition of \u00a0fatty acids of Shami goats milk fat was isolated and identify during lactation using (GC). The results confirmed that the goat milk fat contained a higher proportion of the following fatty acids: (Cabreuec, Cabrelic, Cubric, of Luric), and medium and short-chain saturated\u00a0 Fatty acids compared with cow’s milk.\u00a0 It\u00a0 contained a higher proportion of fatty acid linoleic, while contained less \u00a0Butric \u00a0acid than the cow’s milk fat. The results showed that there were no significant changes in fatty acids of goat milk fat during lactation.<\/strong> \u00a0\u00a0\u00a0\u00a0\u00a0The atomic absorption was used to determine the concentration of mineral elements, The results showed high nutritional value of milk Shami goats, due to the high content of important calcium, phosphorus, magnesium, iron, zinc and manganese, compared with cow’s milk mineral elements. The study also confirmed the effect of the process of lactation on the concentration of metallic elements during different months.<\/p>\n","protected":false},"excerpt":{"rendered":"
