Abstract :

مطالعه حاضر با هدف بررسی اثرات شمارش یاخته­های پیکری (SCC)، SCC افتراقی (ماکروفاژ (MAC)، لیمفوسیت (LYM) و لوکوسیت­های چندهسته­ای (PMN))، تعداد و مرحله شیردهی بر ترکیب شیر در شیر شتر و گاو صورت گرفته است. شیر شتر به طور معنی­داری (05/0>P) حاوی مواد معدنی بیشتری است. سطح لیپولیز در شیر شتر مشابه شیر گاو است. سطح لیپولیز همگام با افزایش سطح MAC در شیر شتر افزایش یافته ولی در شیر گاو چنین نیست. نتایج حاصل نشان می­دهد که MAC در تجزیه چربی شیر شتر نقش­آفرینی می­کند. ترکیب مواد معدنی به طور معنی­داری تحت تأثیر SCC در شیر شتر واقع می­شود. ترکیب شیر تحت تأثیر تعداد دوره شیردهی در هر دو گونه قرار نمی­گیرد. سطح کل جامدات شیر، کلسیم و سدیم در شیر شتر همگام با پیشرفت دوره شیردهی، کاهش می­یابد.
