Segmentación de consumidores según su actitud frente al bienestar animal en Santiago y Viña del Mar
(Universidad de Chile, 2013)
An alternative to add value to beef is the incorporation of confidence attributes, one of which might be to guarantee that it has been produced under procedures of animal welfare. In order for this strategy to be successful, it is relevant to know...

Modificación de las condiciones de crianza y crecimiento en etapa larval y juvenil en pez cebra (Danio rerio)
(Universidad de Chile, 2011)
El pez cebra (Danio rerio) es uno de los vertebrados más utilizados como organismo modelo en biología molecular y del desarrollo, fisiología y toxicología. Recientemente se ha propuesto como organismo modelo en estudios de nutrición y crecimiento...
The zebrafish (Danio rerio) is one of the most common vertebrates as a model organism in molecular and developmental biology, physiology and toxicology. Recently it has been proposed as a model organism in studies of nutrition and growth. However, have not been established protocols for larval rearing which makes it difficult to generate large numbers of adult fish, a prerequisite for using zebrafish as a model for aquaculture. Recently it has been proposed as a model organism in studies of nutrition and growth where the results could be applied to important fish in aquaculture. A prerequisite for using zebrafish as a model for aquaculture is to generate a large numbers of adult fish, however, have not established appropriate protocols for larval rearing which makes the task of generating plenty of adults. The survival of the larvae depends on both the supply and physicochemical conditions of the environment where they are, however, most of these parameters are relatively established only for the maintenance of adult fish. For example, the level of dissolved oxygen in the water in the larval stage has not been described. The aim of this study was to determine the optimal conditions for rearing larval zebrafish from 8 to 28 days post fertilization (dpf), once the transition occurs from larva to juvenile, and know the growth of the larvae until 98 dpf, prior to sexual maturity. We evaluated the survival of larvae exposed to a condition of no aeration and constant aeration in 24 families of fish during the first 28 dpf. We compared the growth rate of fish under constant aeration from 28 dpf to 98 dpf, fed with two experimental diets differing in protein source (animal v/s plant). Additionally, growth curves were obtained for fish fed with experimental diet based on animal protein and commercial food. The results indicate that increased mortality of fish larvae register under no aeration condition with a mortality 52.81% versus 4.95% in that population under constant aeration. In both trials, the highest mortality was recorded between 12 and 14 dpf, in addition to the treatment without aeration showed an increase in mortality between 22 and 25 dpf, probably due to environmental hypoxic conditions. Moreover, the populations fed diets differing in protein source had significantly higher values in weight and length in those fish fed with animal protein versus those fed plant protein (181.964 ± 62.952 mg and 15.963 ±1.862 mm versus 135.204 ± 55.701 mg versus 14.227 ± 2.340 mm). By comparing the growth curves for fish fed diet based on animal protein and commercial diet were fitted to potential model ( for growth, where that population fed commercial diet that showed greatest increases in weight and length (P > 0.05)....

Preferencias alimentarias en perros: efecto del sexo, raza, edad y peso sobre la elección de dietas comerciales
(Universidad de Chile, 2015)
Las pruebas de preferencia permiten estudiar la conducta alimentaria de perros
domésticos; sin embargo, ciertas variables intrínsecas podrían afectar los resultados
obtenidos. La presente memoria evaluó el efecto del sexo, raza, edad y peso sobre el
consumo total, consumo por peso metabólico y preferencia de dietas preferidas en
perros domésticos, y la posible relación de los componentes nutricionales de esas dietas
con las preferencias observadas. El sexo, edad y peso de los perros mostraron tener un
efecto sobre el consumo y consumo corregido por peso metabólico frente a dietas
preferidas (P < 0,04). En relación a las preferencias, el sexo no mostró tener efecto
(Beagle P = 0,370; Labrador P = 0,815), mientras que el peso influyó en las
preferencias de todas las razas (P < 0,041) mostrando una correlación positiva en
Beagle (r = 0,010; P = 0,050) y Bóxer (r = 0,183; P = 0,183) pero negativa en Labrador
(r = -0,152; P = 0,011). Por otra parte, la edad solo tuvo efecto en las preferencias de
perros Beagle (P = 0,005) mostrando una correlación positiva (r = 0,085; P = 0,003). La
materia seca y el extracto no nitrogenado mostraron correlaciones negativas con las
preferencias (r = -0,239; P = 0,008 y r = -0,188; P = 0,039) respectivamente. Al igual
que algunos componentes de la dieta, el peso, la edad y la raza podrían afectar las
preferencias alimentarias de perros domésticos siendo necesario considerar estas
variables al momento del diseño y análisis de las pruebas....
