Consequences of infection pressure and protein nutrition on periparturient resistance to Teladorsagia circumcincta and performance in ewes
(2009)The consequences of protein nutrition on the degree of periparturient relaxation of immunity to nematode parasites in sheep may be more pronounced at higher levels of infection pressure. Here, we investigated interactive ... -
Consequences of protein supplementation for anorexia, expression of immunity and plasma leptin concentrations in parasitized ewes of two breeds
(2009)The periparturient relaxation of immunity (PPRI) against parasites in ewes has a nutritional basis. We investigated whether ewes experience a reduction in food intake (anorexia) during PPRI and if the magnitude of anorexia ... -
Dietary protein and energy supplies differentially affect resistance to parasites in lactating mammals
(2011)Periparturient relaxation of immunity (PPRI) to parasites in mammals results in higher worm burden and worm egg excretion and may have a nutritional basis. Nippostrongylus brasiliensis re-infected lactating rats fed low-crude ... -
Immunonutrition: Nutritional control of parasites
(2006)Whilst it has long been known that improved protein nutrition can increase resilience, i.e. reduce the consequences of subclinical gastrointestinal nematode parasitism on sheep performance, improved protein nutrition can ... -
Nutritional sensitivity of periparturient resistance to nematode parasites in two breeds of sheep with different nutrient demands
(2010)The periparturient relaxation of immunity (PPRI) to parasites in mammals is sensitive to both metabolisable protein (MP) supply and animal genotype (different reproductive outputs). We tested the hypothesis that the ... -
Nutritional sensitivity of resistance to Trichostrongylus colubriformis in lactating ewes
(2009)It has been suggested that the periparturient breakdown of immunity to parasites has a nutritional basis. Our overall hypothesis is that it results from a prioritized scarce metabolizable protein (MP) allocation to ...
