Thirty nine Friesian cows during a time period of five months, and experimental animals were divided into four groups according to the production season (the first, third and fifth), and added a mixture of vitamins and minerals (premix) by different ratio\u00a0\u00a0 of \u00a0the\u00a0 concentrate feed mixture\u00a0 for all experimental\u00a0 groups (0, 0.25 , 0.50 , 1 g\/ kg). The objective of this research is to study the effect of supplement different levels of a mixture of vitamins and minerals (premix) to experimental rations on milk composition (fat) in Friesian cows of different milking seasons. The results showed that there are no significant differences in a milk fat due to the premix used in the feeding mixture, meanwhile it does exist among the milk seasons. The results also showed that there were significant differences (<em>P<\/em>\u22640.05) in milk fat according to the different productive season of the cow as the first season exceeded both the third and fifth season by the percentage of milk fat.<\/p>\n<p><strong>Keyword:<\/strong> premix, Friesian cows, fat milk.<\/p>\n<p>Full paper in Arabic:\u00a0<a href=\"http:\/\/agri-research-journal.net\/SjarEn\/wp-content\/uploads\/11.pdf\">PDF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Smaa Dabdob* (1) (1).
