Efectos de los factores dietéticos sobre la conducta agresiva y otras patologías del comportamiento del perro

Studies show that feeding patterns, environmental conditions, and pet management mainly affect animal health, behavior and welfare. However, little epidemiologic data exist about pet dog feeding habits and management and canine behavior, especially aggression. Moreover, it is well known that serotonin is involved in aggression: a diet low in tryptophan (serotonin precursor) with high levels of neutral amino-acids could decrease the central levels of serotonin and increase the expression of aggression and impulsiveness in several domestic animals. oreover, brain levels of serotonin in humans and other species can be increased by physical activity. In this study we alysed the effects of diet management, supplementation and regular physical activity on oncentration of serotonin in a population of non aggressive dogs. The general aim of the study is to determine the effect of environmental factors on the dogs’ feeding habits as well as the relationship between the type of food provided and management and behavioral problems in dogs. The specific objectives were: characterization and comparison of different physiological and blood parameters between dogs with and without behavior pathologies. Observation of the impact of the diet and managment factors (exercise, education) on those parameters and on dog’s behavior, with particular attention to aggression. This study is divided into three phases, according with the objectives. Firstly, characterization of the dogs’ characteristics and serics profiles on the basis of the blood tests. Comparison between the values noticed on animals without any behavior pathology and animals with behavior disorder to point out the difference between the biochemical parameters of the two groups. Secondly, the purpose of the second phase is to verify whether a type of food is able to affect the biochemical paramenters of a population of non-aggressive dogs. Thirdly, the goal is to evaluate the effects of different diet factors, management and physical exercise on the canine aggression.

Preventive medicine for epidemic outbreaks and risky behavior through mobile devices and ubiquitous computing

In this work, we have developed the first free software for mobile devices with the Android operating system that can preventively mitigate the number of contagions of sexually transmitted infections (STI), associated with risk behavior. This software runs in two modes. The normal mode allows the user to see the alerts and nearby health centers. The second mode enables the service to work in the background. This software reports the health risks, as well as the location of different test centers.

Influència de la restricció alimentària i del maneig presacrifici sobre el benestar i la qualitat de la canal i la carn en porcí

S’han estudiat un total de 75 mascles sencers (50% Pietrain, 25% Duroc i 25%Landrace) des de les dues setmanes de vida (±4,00kg) en el Centre de Control Porcí del’IRTA (CCP) fins les 24 hores posteriors al seu sacrifici (±100,00kg) a l’escorxador delCentre de Tecnologia de la Carn de l’IRTA (CTC). Al CCP es varen avaluar aspectes decomportament i benestar animal, així com diferents paràmetres de consums icreixements individuals de cada animal. A l’escorxador del CTC es van avaluar lescaracterístiques de qualitat de la canal i la carn de les 75 canals provinents dels animals estudiats. Les dades de consum individual es van poder recollir mitjançant el sistema SACA (Sistema Automàtic de Consum d’Aliment) que permet saber quins són elsconsums individuals de cada animal i en quin moment del dia es produeixen les sevesvisites a la menjadora.L’objectiu era determinar l’efecte del dejuni en granja (DJ) i del temps d’esperaen l’escorxador (TE) sobre el benestar animal, la qualitat de la canal i la carn de porc iel que es van anomenar altres variables i ràtios. També es van analitzar els consumsindividuals d’aliment per cada animal. Es van tenir en compte dos períodes de dejuni (2i 12 hores) i tres temps d’espera en l’escorxador (0, 5 i 10 hores)
