Hyperphagia was induced in mice by p.o. administration of different types of CNS depressant drugs, like chlordiazepoxide 25 mg/kg diazepam 2.5 mg/kg, cyproheptadine 2 mg/kg and phenobarbitone 25 mg/kg. Such hyperphagia was abolished by pretreatment with naloxone 0.1 mg/kg sc. Naloxone per se at this dose produced no significant effect on the food intake. This is suggestive of the role of peptid...

Insect societies are often described as superorganisms, and there are many functional parallels between organisms and superorganisms. Elegant work using ants shows that nutrient regulation, which occurs in many non-social animals, can also occur at the colony-level.

We investigate models for animal feeding behaviour, with the aim of improving understanding of how animals organise their behaviour in the short term. We consider three classes of model: hidden Markov, latent Gaussian and semi-Markov. Each can predict the typical 'clustered' feeding behaviour that is generally observed, however they differ in the extent to which 'memory' of previous behaviour i...

Feeding behaviour is modulated by both environmental cues and internal physiological states. Appetite is commonly boosted by the pleasant smell (or appearance) of food and destroyed by a bad taste. In reality, animals sense multiple environmental cues at the same time and it is not clear how these sensory inputs are integrated and a decision is made to regulate feeding behaviour accordingly. He...

this study was conducted to evaluate the age-specific functional response of psyllaephagus zdeneki noyes & fallahzadeh (hymenoptera: encyrtidae) at different nymph densities of olive psyllid, euphyllura pakistanica loginova (hemiptera: psyllidae). due to parasitoid behaviour of feeding and parasitizing the host, both traits were separately explored on a daily functional response. results of...

BACKGROUND Oral aversion and feeding disorders occur frequently after long-term feeding via a tube. A rapid home-based tube-weaning programme that provides feeding disorder treatment under medical supervision to overcome oral aversion has been developed. AIMS To describe the results of the 4-10-day rapid home-based feeding tube-weaning programme and to determine the prevalence of food aversio...

Twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. Treatments consisted of 8 (T1), 4 (T2) or 2 (T3) feeding buckets/pen (8 lambs/pen). During the experiment, concentrate was fed at 08:30 in individual feeders. Daily dry matter intake (DMI...
