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 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 ...

Sixteen 2-year old female sheep were fitted with rumen and duodenal cannulae at the Johnstone Memorial Laboratory, Lincoln University during 1989-1990. They were offered, at 2 hourly intervals, a pelleted concentrate diet ...

Sixteen 2-year old female sheep were fitted with ruminal and duodenal cannulae at Johnstone Memorial Laboratory, Lincoln University during 1989–90. They were offered, at 2 hourly intervals, a pelleted concentrate diet (900 ...

Rumen and caecal digesta were collected, under anaesthetic, from eight sheep offered either hay, pelleted concentrate or pasture at the Johnston Memorial Laboratory, Lincoln University during 1991. Subsamples of digesta ...

In spite of the significant benefits that can be derived from training on safe and efficient agrichemical application and management, many primary producers do not undertake formal agrichemical training. An identified ...

Measuring consumer benefits associated with a policy or a project in a world where prices and outcomes are known with certainty is, at least in theory, straightforward. Changes in consumer surplus provide an appropriate ...

Previous research trials with captive possums in pens, and in the field, have shown that a long-lasting aversion to 1080 cereal bait can be induced in this species (Hickling 1994; Morgan et al. 1996). Research investigating ...

Aversions caused by sub-lethal doses of sodium monofluoroacetate (1080) apparently persist in captive possums for at least 3 months, during which time such possums remain averse (or 'shy') to bait containing either a chronic ...
