| چکیده | ||
| سلنیوم یک ریز مغذی مهم در گاوهای شیری است. این ریز مغذی یکی از آنتی اکسیدان‌های مهم مشتق شده از خوراک است. امروزه به دلیل راهکارهای موجود در بخش کشاورزی، معمولاً در خاک کمبود سلنیوم وجود دارد. بنابراین، مصرف مکمل آن در جیره دام توصیه می‌شود. مکمل سلنیوم علاوه بر این که باعث بهبود عملکرد دام می‌شود، می‌تواند در صورت مصرف بیش از حد سمی بوده و اثرات جبران ناپذیری بر تولید گله داشته باشد. به طور کلی مکمل سلنیوم را برای ترکیب و جذب بهتر به شکل آلی در جیره استفاده می‌کنند که در نتیجه موجب بهبود عملکرد در گاوها می‌شود. به همین دلیل شکل آلی سلنیوم بر شکل معدنی آن ترجیح داده می‌شود. مکمل جیره غذایی حاوی سلنیوم آلی در دورۀ شیردهی و دورۀ انتقال باعث بهبود عملکرد سیستم ایمنی و سلامت رحم و به دنبال آن بهبود عملکرد تولیدمثل می‌شود. | ||

| چکیده [English] | ||
| Selenium is an important micronutrient in dairy cows. Selenium is one of the important antioxidants derived from feed. Today, due to the solutions available in the agricultural sector, there is usually a lack of selenium in the soil, so its supplemental use in animal rations is recommended. In addition to improving livestock performance, Selenium supplementation can be toxic if consumed excessively and have irreparable effects on herd production. In general, Selenium supplements are used for better combination and absorption in the organic form in the diet, which results in improved performance in cows, for this reason, the organic form of selenium is preferred over its mineral form. Dietary supplement containing organic Se during the lactation and transfer period improves the function of the immune system and the health of the uterus, followed by the improvement of reproductive performance. | ||
