Fertility in Dairy Herds - Advanced Part 1: What does poor fertility cost?
نویسنده
چکیده
Recent data from many countries suggests that this decline in fertility may have slowed for example, the Scandinavian countries have now shown that selection for fertility can result in improvements without major effects on milk yield. However, irrespective of general trends in fertility, there are still large differences between farms, which means that on most farms fertility could be improved. Highly productive farms tend to have good fertility; farms with poor fertility tend to be less productive. At the herd level, productivity is no excuse for poor fertility.

Introduction It is now widely recognised that reduced fertility in dairy herds is one of the most important factors affecting producer profitability.
