TLDR
The results are consistent with the view that sheep given a choice between two appropriate foods will modify their diet selection in order to moderate the adverse effects of subclinical nematode infection.About:

Voluntary food intake and diet selection in farm animals.
TL;DR: Feeding behaviour feedback signals ruminant gastrointestinal tract metabolites and hormones central nervous control integrative theories of food intake control growth and fattening reproduction and lactation diet digestability and concentration of available energy specific nutrients affecting intake.

Direct anthelmintic effects of condensed tannins towards different gastrointestinal nematodes of sheep: in vitro and in vivo studies
TL;DR: The lowest intestinal worm burden was recovered from sheep drenched with 8% w/w Quebracho extract and the administration of Que bracho extract at 8% of food intake for 3 days did not affect FEC or worm burdens in sheep infected with the abomasal species compared to controls.

Nutrition-parasite interaction
R.L. Coop,Ilias Kyriazakis +1 more
TL;DR: The framework is useful at highlighting areas of future research on host/parasite/nutrition interactions and can account for the observations of the periparturient relaxation of immunity in reproduced females, as well as the reduction in worm burden in small ruminants supplemented with additional protein.
Journal ArticleDOI
Nutrition and parasite interaction
R.L. Coop,P.H. Holmes +1 more
TL;DR: The main effect of protein supplementation is to increase the rate of acquisition of immunity and increase resistance to reinfection and this has been associated with an enhanced cellular immune response in the gastrointestinal mucosa.
Journal ArticleDOI
Acquired Aversions as the Basis for Varied Diets of Ruminants Foraging on Rangelands
TL;DR: The subtle ways in which aversions diminish preference and cause animals to eat a variety of foods are discussed, one which encompasses the avoidance of toxins and the acquisition of nutrients.

Diet selection in sheep: the ability of growing lambs to select a diet that meets their crude protein (nitrogen × 6.25) requirements
Ilias Kyriazakis,J. D. Oldham +1 more
TL;DR: The results suggest that sheep were able to select a diet that meets their CP requirements and avoid, at least to a certain extent, excess of protein intake.

The effect of post-ruminal infusion of protein or energy on the pathophysiology of Trichostrongylus colubriformis infection and body composition in lambs
TL;DR: In this article, the effect of post-ruminal infusion of protein or energy on the pathophysiology of Trichostrongylus colubriformis infection and body composition in lambs was investigated using the comparative slaughter technique.

Specific identification of strongyle eggs in small samples of sheep faeces.
M. Christie,F. Jackson +1 more
TL;DR: A method for the specific identification of strongyle eggs in small samples of sheep faeces based on dimensional and biological characteristics is described and more than 90 per cent of the eggs of Ostertagia spp and of Trichostrongylus vitrinus can be positively identified.
