Extract

It has been proposed that the occurrence of the periparturient relaxation in immunity (PPRI) to gastrointestinal parasites is due to a lower partial priority of nutrient allocation to the immune functions, rather than to the reproductive functions, when parasitized hosts are offered scarce nutrient resources (Coop and Kyriazakis, 1999). This implies that immune functions directed towards gastrointestinal parasites will benefit from an increased supply from scarce resources, such as metabolizable protein (MP) and metabolizable energy (ME). In this experiment we studied whether the resistance in parasitized pregnant sheep is affected by an increased supply of MP, or ME, or both.
