Studies were conducted to investigate whether continuous exposure to an aversive mixture, presented in a self-feeder in the field, would accomplish persistent intake of the aversive mixture and thereby sustain aversion of sheep to Geigeria ornativa. Fifteen 2-year-old Dorper wethers averted to G....

Studies were conducted to address conditioned flavour aversion (CFA) and place avoidance learning in hamsters given injections of alkaloid extracts from tall larkspur (Delphinium barbeyi), determine if larkspur had reinforcing or negative properties sufficient to cause place avoidance or preference ...

This article describes a modified method to teach cattle to avoid yellow tulp (Moraea pallida) while grazing pastures in South African conditions. It was shown that the combination of intramuscular injection with epoxyscillirosidin and drenching with lithium carbonate was effective in aversion...

Many of the nutritional challenges posed by alternative systems can be addressed by application of existing scientific knowledge. However, regulations applied to alternative systems may limit the nutritionist's freedom of action, particularly with regard to the ingredients which can be used to...

Trajectories of food intake for 12 sets of animals (weekly average intakes of four individual growing sheep, mean daily intakes of four pens of three growing cattle, and the mean daily intakes of four groups of six pregnant fallow does) were examined. The raw data exhibited expected seasonal...

A total of 27 female quails (Coturnix coturnix) were divided into 3 groups which were fed diets containing 0, 1 or 3 mg potassium cyanide (KCN) in a toxicological study. In another study, 20 female were fed both a control diet or a diet containing 1% sodium sulfate for 2 days, after which they were ...

Field studies were conducted in Rio Grande do Norte, Brazil, to determine whether lithium chloride (LiCl)-treated sheep could be averted from consuming Mascagnia rigida in the edaphic and climatic conditions of a semi-arid region of northeastern Brazil. Twelve 10- to 12-month-old female sheep were...

Browsing of coffee plants by sheep is one of the major limitations to introducing sheep grazing on coffee plantations. Hence, it is worth finding a mechanism that will prevent animals browsing coffee plants. Emetic agents like lithium chloride (LiCl) have been used successfully in different animal...
