Studies examining the etiology of obesity often focus on the relationship between taste, overeating, and the developnlc~r. of obesity. One animal model often used to study obesity, rats with lesions of the ventromedial hypothalamus (VMH) , is popular because the degree of overeating and obesity in that animal is particularly sensitive to the taste qualities of the food the rat eats. The exagger...

BACKGROUND Reducing antibiotics overuse in animal agriculture is one key in combat against the spread of antibiotic resistance. Probiotics are a potential replacement of antibiotics in animal feed; however, it is not clear whether and how probiotics and antibiotics differ in impact on physiology and microbial ecology of host animals. RESULTS Host phenotype and fecal microbiota of broilers wit...

Electronic Olfaction Systems (EOSs) based on a variety of gas-sensing technologies have been developed to simulate in a simplified manner animal olfactory sensing systems. EOSs have been successfully applied to many applications and fields, including food technology and agriculture. Less information is available for EOS applications in the feed technology and animal nutrition sectors. Volatile ...

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...

background & aim: a feeding trial was conducted to investigate the effect of periodically use of garlic on growth ‎performance, and antibody titer to newcastle and infectious bursal diseases in broiler ‎chickens. experimental: ross broiler chicks randomly allocated into the 10 dietary treatments ‎for 6 weeks. a 3 × 4 factorial experiment was used as three periods of feeding (starter, grower...

A consensus of the Workgroup on Community and Socioeconomic Issues was that improving and sustaining healthy rural communities depends on integrating socioeconomic development and environmental protection. The workgroup agreed that the World Health Organization's definition of health, "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity,...

Gossypol, a substance found naturally in cottonseed and cottonseed products has been the subject of numerous research projects and articles in the past. However, controlling gossypol intake is still a concern in many livestock classes. This review article includes a summary of the classical information on limits and effects as well as results from recent research projects with immature and adul...

PROBLEM To determine whether neighbors around manure lagoons and massive hog confinement buildings who complained of offensive odors and symptoms had impaired brain and lung functions. METHOD We compared near hog manure neighbors of lagoons to people living beyond 3 kilometers in Ohio and to unexposed people controls in a nearby state for neurophysiological, cognitive, recall and memory funct...
