Conditioned taste aversions: how sick must a ruminant get before it learns about toxicity in foods?
Contributor(s):: Toit, J. T. du, Provenza, F. D., Nastis, A.
To determine if the food-avoidance learning abilities of large herbivores are as poorly developed as has previously been assumed, the relationship was investigated between the acquisition of a conditioned taste aversion (CTA) by sheep and the dose of gastrointestinal poison (LiCl) administered...
Disorders in the feeding behaviour of fattening bulls
Contributor(s):: Sambraus, H. H.
For labour-saving reasons, fattening bulls in West Germany are commonly housed on slatted floors and fed only on maize silage and concentrates. Bulls kept under these conditions quite frequently show disturbances associated with feeding behaviour. In four fattening-bull enterprises 2 of the...

Selective grazing behaviour in horses: development of methodology and preliminary use of tests to measure individual grazing ability
Contributor(s):: Marinier, S. L., Alexander, A. J.
The selective grazing behaviour of 5 plant species measured by the "two-hand" method by 12 horses of various breeds 1.5 to 18 years old was investigated. Results were analysed in relation to 5 measures of choosing behaviour: the strength of the choice; correspondence between first bite and the...
Socially induced diet preference ameliorates conditioned food aversion in lambs
Contributor(s):: Provenza, F. D., Burritt, E. A.
To determine whether a socially induced diet preference could ameliorate a conditioned food aversion in lambs one group was conditioned to avoid the shrub Cercocarpus montanus by giving them lithium chloride, a toxin that produces strong food aversions, following shrub ingestion. On day 1 of...
The effect of naloxone on nursing behavior in Brahman calves
Contributor(s):: Lay, D. C., Jr., Friend, T. H., Dellmeier, G. R., Randel, R. D., Bowers, C. L., Mal, M. E., Zavala, P.
In 3 experiments in which calves were injected s.c. with saline or naloxone (at 1, 1.5 or 3 mg/kg body wt), no significant effects of naloxone on sucking behaviour were observed, although there was a tendency for naloxone-treated calves to spend less time sucking than did saline-treated calves....
Amount and diurnal distribution of grazing time by stocker cattle under different tall fescue management strategies
Contributor(s):: Coffey, K. P., Moyer, J. L., Brazle, F. K., Lomas, L. W.
The effects of endophyte level, ladino clover interseeding, grazing management or supplemental antibiotics on stocker cattle performance and the amount and diurnal distribution of grazing time by stocker cattle on tall fescue (Festuca arundinacea) pastures was evaluated. Grazing time was measured...
