An experiment was conducted with 48 Yorkshire x Berkshire
crossbred barrows to evaluate the influence of varying Calorie: protein ratios in high-fat rations on performance and carcass quality

Rapid copper depletion without clinical symptoms of copper deficiency

Copper metabolism was influenced by grass species fed to the animals.
Tall fescue, Festuca arundinacea Schreb. 'Altar and 'Fawn', reduced
liver copper stores and decreased blood plasma copper and ceruloplasmin
activity to...
A Cr₂0₃, and cellulose fibre mixture was used with cattle, in
three grazing and two semi-restricted experiments, to study the mode
of its excretion, the possibility of using it in a once-daily dosing and
grab-sample regime to estimate fecal output and in a field experiment
to test a hypothesis involving...
The objective of the thesis was to determine the effects of
isolated coumestrol on the growth, carcass characteristics and
certain organs of wether lambs. The first of two trials was conducted
over an eight week period with two groups of heavy wether
lambs. Trial two was conducted over an 11...
