چکیده مقاله :
سم‌چینی به عنوان یکی از فرآیندهای مدیریتی مهم در دامداری‌های صنعتی شناخته می‌شود. هر فرآیند مدیریتی نیاز به زمان بندی و اجرای دقیق دارد تا بتواند بهترین بهره‌وری را برای دام و صنعت ایجاد کند. در این مقاله تلاش شده است تا با مرور مقالاتی که به دنبال زمان مناسب برای سم‌چینی بوده‌اند به یک جمع بندی مناسب برای زمان‌بندی این کار در گله دست یابیم. هرچند با توجه به مطالعات انجام گرفته، نیاز به تحقیقات جامع در این زمینه احساس می‌شود، اما مطالعات انجام گرفته توانسته‌اند تا حدودی به ما درباره‌ی زمان مناسب سم‌چینی کمک کنند. محدوده‌های زمانی که در مطالعات به آن‌ها پرداخته شده است شامل حوالی خشکی، ابتدای شیرواری و میانه و انتهای شیرواری است، که در این مقاله با هم به بررسی آن‌ها می‌پردازیم. در پایان به اهمیت ثبت دقیق اطلاعات برای یافتن زمان مناسب برای سم‌چینی تاکید شده است.
Hoof trimming as a part of hoof health management is one of the important parts of herd health management system. Timing of hoof trimming and its method are the main subjects that must be known for an efficient hoof trimming program. In the current study, the different suggested timings of trimming (around drying, early, middle and end of lactation) have been reviewed. Although the need for more research to find the best time for hoof trimming is yet necessary, an appropriate timing is suggested based on the current literature. Also the unique role of accurate data recording system in time management of trimming is mentioned.
