Abstract

The periparturient relaxation in immunity (PPRI) to nematode infection in ewes is well known and it is associated with a rise in faecal egg counts during the periparturient period. In order to assess an eventual relationship between the PPRI and the nutritional status of periparturient females, a twoyear study was carried out in a dairy goat flock. On year 1, pregnant does were fed at 26 % below their energy (UFl) requirements and 5 % above their protein (PDI) ones during the last 3 weeks before parturition (week 0) and an increase in nematode egg counts occurred from week -2 to week +4 with a predominance of Oesophagostomum larvae in coprocultures. In year 2, two groups of pregnant goats were fed at about 100 % their energy requirements and 28 and 44 % above the protein requirements respectively during the same period. In this latter situation, no nematode egg count increase occurred in any of the two groups of animals, Teladorsagia and Trichostrongylus being the prevalent larval genera in coprocultures. As the study covered two consecutive years, the implication of several factors related to host physiology, parasite epidemiology and host nutrition are discussed.
