Pregnancy diagnosis in small ruminants
Keywords:pregnancy diagnosis, pregnancy-associated glycoproteins (PAG), ultrasonography, small ruminants
Pregnancy diagnosis in small ruminant species is crucial for the management of sheep and goats, particularly in commercial settings. There are many options for pregnancy diagnosis in these species, including ultrasonography and blood-based assays to detect pregnancy-associated glycoproteins. The method used often depends on the availability of veterinary services to perform pregnancy diagnosis and the management goals of the herd or flock. Regardless of the method chosen, it should be economical for the producer, easily performed in field conditions, and highly accurate. Additional information on gestational age and fetal number allows for improved nutritional management of the herd or flock to ensure adequate nutrition in the periparturient period to prevent metabolic disease such as pregnancy toxemia. Providing these diagnostic services can be an important source of revenue for the veterinarian while providing invaluable information to aid small ruminant producers in improving profitability in their herds and flocks.
