چکیده مقاله :
تلقیح گاوهای سرویس دوم بر اساس بازگشت به فحلی از نظر اقتصادی کارآمدترین روش برای تلقیح دوم است.
استفاده از یک سیستم همزمان سازی دوباره، به طور کلی با کاهش فاصله بین تلقیح برای گاوهای غیرآبستن، بهره‌وری را افزایش می‌دهد.
اگر از یک سیستم همزمان سازی دوباره استفاده شود، مهم ترین ملاحظات عبارتند از:
فاصله بین اولین تلقیح و تلقیح همزمان سازی دوباره.
نرخ گیرایی تلقیح همزمان سازی دوباره.
سرعت و دقت روش تشخیص آبستنی.
Inseminating second-service cows based on an observed return to estrus is the most economically efficient method for second insemination.
Employing a resynchronization system will generally increase efficiency by reducing the interval between inseminations for cows that are not pregnant.
If a resynchronization system is used then the most important considerations are:
The interval between the first AI and the resynchronized AI;
The conception rate of the resynchronized AI;
The speed and accuracy of the pregnancy diagnosis method.
The short resynchronization program reduced the time to pregnancy because of a reduction of the inter-insemination interval for cows with a CL at non pregnancy diagnosis.
