چکیده مقاله :
تعیین سن، در دامهای اهلی اهمیت بسزائی دارد زیرا علاوه بر اینکه بهداشت، تغذیه و تعلیف تابع سن میباشد از لحاظ علم دامپزشکی نیز بعضی از بیماریهای مشخص وابسته به سن بوده و در سنین معینی ظاهر میشوند. از این رو اطلاع از چگونگی تعیین سن در دامهای اهلی برای دامپزشکان چه از نظر پیش بینی و پیشگیری امراض و چه از لحاظ درمان اهمیت ویژهای دارد. علاوه بر آن دانستن سن دام برای دامپروران از نظر بهره برداری و بکار گماردن حیوان در سرویسهای مختلف یکی از نکات اساسی محسوب میشود و در قیمت واحد دامپروری اثر محسوسی دارد. یکی از روشهای تعیین و قضاوت سن دامهای اهلی استفاده از تعداد، شکل و زمان رویش دندانها است. لذا هدف از نگارش این مقاله ارائه اطلاعات کاربردی و عملی جهت تعیین سن در گونههای نشخوارکنندگان و شترسانان بصورت خلاصه میباشد که با بررسی مقالات و منابع موجود در طی سالهای اخیر انجام گرفت. امید است این مقاله برای افزایش سطح آگاهی کلیه دانشجویان دامپزشکی، کلینیسینهای فعال در زمینه دامهای بزرگ، علاقمندان به دندانپزشکی حیوانات و دیگر رشتههای وابسته مفید واقع شده و به آن رجوع کنند.
Determining age is very important in domestic livestock because in addition to health, nutrition and grazing, from point of veterinary science some of the special disease it is age dependent and appear at certain ages. Therefore, knowing the age of domestic livestock for the farmers both in terms of anticipating and preventing diseases and in terms of treatment is important and have a significant effect on exploitation, usage of animals in different services and the cost of farm. One of the methods of determining and judgment of the age in domestic animals is the use of the number, shape and date of tooth eruption. Therefore, the purpose of this paper is to provide practical and useful information for determining the age in ruminants and camelids, as reviewed by peer-reviewed articles and resources in recent years. We hope that this article will be useful to all students of veterinary medicine, active clinicians in large animals field, animal dentistry enthusiasts and other related businesses.
