| چکیده | ||
| به منظور تعیین اثرات سدیم استات و اسید لینولئیک مزدوج (CLA) بر میزان ماده خشک مصرفی، قابلیت هضم خوراک، عملکرد و پروفایل چربی شیر، از 33 رأس گاو هلشتاین چند نوبت زایش طی روزهای 5-31 بعد زایش در قالب طرح کاملاً تصادفی با سه تیمار و 11 تکرار استفاده شد. جیرههای آزمایشی شامل 1-جیره پایه ، 2- جیره حاوی300 گرم مکمل سدیم استات، 3- جیره حاوی 100 گرم مکمل CLA بود. ماده خشک مصرفی و تولید شیر بهصورت روزانه، وزن بدن و نمره وضعیت بدنی در ابتدا و انتهای آزمایش اندازه گیری و نمونه شیر با فواصل منظم برای تعیین مقدار ترکیبات شیر گرفته شد. همچنین، در روز پایانی یک نمونه برای تعیین پروفایل اسیدهای چرب شبر گرفته شد. اختلاف معنیداری بین گروه دریافتکننده سدیم استات و CLA با گروه شاهد برای ماده خشک مصرفی مشاهده نشد )05/0(p>. با مصرف سدیم استات و CLA تولید شیر بهترتیب 16/3 و 46/2 کیلوگرم در روز نسبت به تیمار شاهد افزایش معنیداری یافت. همانطور که انتظار میرفت مقدار چربی شیر با تیمار CLA کاهش داشت. با مصرف CLA توازن منفی انرژی تغییر معنیدار نداشت که علت آن صرف انرژی ذخیره شده برای تولید شیر بیشتر میباشد. مصرف CLA توانست با افزایش انتقال ایزومر ترانس 10 سیس 12 CLA به شیر و کاهش شاخصهای ترومبوژنیک و آتروزنیک برای سلامت مصرف کننده شیر مفید باشد. تولید و درصد پروتئین و لاکتوز شیر بین تیمارها تفاوت معنیداری نداشت. عرضه استات سدیم باعث بهبود سنتز شیر و چربی شیر در گاوهای شیری شد، در نتیجه فرض لیپوژنیک بودن استات در بافت پستان تأیید شده است. در حالیکه، سدیم استات باعث منفیتر کردن توازن منفی انرژی و افزایش شاخص آتروژنیک و ترومبوژنیک شد. | ||

| چکیده [English] | ||
| In order to determine the effects of sodium acetate and conjugated linoleic acid (CLA) on dry matter consumed, feed digestibility, milk yield and milk fat profile, 33 Holstein cows several calving times during days 5-31 after calving in a completely randomized design with Three treatments and 11 replications were used. The experimental diets included 1- basic diet (control), 2- diet containing 300 gr of sodium acetate , 3- diet containing 100 gr of CLA. Daily dry matter intake and milk production, body weight and body condition score were measured at the beginning and end of the experiment. milk samples were taken at regular intervals to determine the amount of milk compounds. Also, on the last day, a sample was taken to determine the profile of fatty acids. Dry matter intake was not significant among dietary treatment (P>0.05). Milk production was increased by supplementing diets with sodium acetate (3.16 kg/d) and CLA (2.46 kg/d) compared to control treatment. CLA supplementing decreased milk fat content significantly and sodium acetate increased it. The yield and content of milk protein and lactose were not significantly different between the treatments. With the consumption of sodium acetate, the amount of milk fat and milk production increased, as probably the hypothesis that sodium acetate is lipogenic for adipose tissue was ignored and Acetate partition nutriunt toward milk fat production. CLA consumtion, negative energy balance did not change between as spared energy partition toward more milk yield. The use of CLA could be beneficial for the health of consumers by increasing the trans-10-cis-12 CLA isomer transfer to milk and reducing thrombogenic and atherogenic indicators. | ||
