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 ... -
The effects of changes in nutritional demand on gastrointestinal parasitism in lactating rats
(2007)Lactating rats experience a breakdown of immunity to parasites, i.e. they carry larger worm burdens after re-infection compared to their non-lactating counterparts. Feeding high-protein foods to lactating rats results in ... -
Effects of maternal protein nutrition and subsequent grazing on chicory (Cichorium intybus) on parasitism and performance of lambs
(2010)Forty-eight 4- to 5-yr-old Blackface x Bluefaced Leicester (Mule) ewes and their 24-d-old twin lambs were used to assess the effects of maternal protein nutrition and subsequent grazing on chicory (Cichorium intybus) on ... -
Exploiting synergisms and interactions in the nutritional approaches to parasite control in sheep production systems
(2008)Occurrence of resistance to anthelmintics and increased awareness about drug residues entering the food chain and harming the environment, have called for a reduction in the regular, preventive use of anthelmintics and an ... -
Genome-Wide Transcriptomic Analysis of Intestinal Tissue to Assess the Impact of Nutrition and a Secondary Nematode Challenge in Lactating Rats
(2011)Background: Gastrointestinal nematode infection is a major challenge to the health and welfare of mammals. Although mammals eventually acquire immunity to nematodes, this breaks down around parturition, which renders ... -
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 ... -
In silico exploration of the mechanisms that underlie parasite-induced anorexia in sheep
(2011)A model was used to investigate two mechanisms describing reductions in food intake (anorexia) observed during gastrointestinal parasitism in lambs, and to explore relationships between anorexia and food composition. The ... -
Medicinal plants for helminth parasite control: facts and fiction
(2007)The use of medicinal plants for the prevention and treatment of gastro-intestinal parasitism has its origin in ethnoveterinaty medicine. Although until recently the majority of the evidence on the antiparasitic activity ... -
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 ...
