The intake, digestion and protein degradation of grazed herbage by early-weaned lambs
(Cambridge University Press, 1992-09)
Sixty-four intact lambs and twenty-four lambs fitted with a duodenal cannula were weaned at 6 weeks of age and grazed pure species swards of either lucerne (Medicago sativa), white clover (Trifolium repens), ryegrass (Lolium ...
A model of magnesium metabolism in young sheep. Magnesium absorption and excretion
(Cambridge University Press, 1997-12)
A model of Mg metabolism in sheep is proposed. It is based on standard Michaelis-Menten enzyme kinetics to describe the transport of Mg across the rumen wall and passive diffusion to describe the absorption of Mg in the ...
Elevation of feed intake in parasite-infected lambs by central administration of a cholecystokinin receptor antagonist
(Cambridge University Press, 1998-01)
The role of cholecystokinin (CCK) in modulating feed intake depression in parasite-infected lambs was investigated using CCK receptor antagonists (L364–718 and loxiglumide). Four experiments were carried out using ewe lambs ...
A model of magnesium metabolism in young sheep: transactions between plasma, cerebrospinal fluid and bone
(Cambridge University Press, 2004-01)
An extension of the previously proposed model of Mg metabolism (Robson et al. 1997) has been developed to consider the transactions of Mg that are associated with cerebrospinal fluid (CSF) and bone. The representation of ...
Leptin concentrations and the immune-mediated reduction of feed intake in sheep infected with the nematode Trichostrongylus colubriformis
(Cambridge University Press, 2009)
The hypothesis that increases in the concentration of the anorectic peptide leptin may be responsible for the immune-mediated reduction in feed intake (FI) during gastrointestinal parasitism in sheep was investigated. In ...
