Evaluación de una vacuna experimental para inmunocastración en machos porcinos de criadero
(Universidad de Chile, 2016)
la carne del animal. Actualmente el método utilizado para prevenir esta situación en criaderos, es la castración quirúrgica a edad temprana de los cerdos machos, pero esta práctica presenta desventajas relacionadas con el bienestar y eficiencia...
The objective of the present study is to carry out an on-site evaluation for a vaccine formulation, produced to induce immunocastration in boars. The action mechanism of this vaccine occurs through the production of antibodies against Gonadotropin-releasing hormone (GnRH), blocking its effect and thus, the negative features associated to the production of functional male swine, such as the ―boar taint‖, which causes an unpleasant smell and flavor in the animal meat. The current method, in order to prevent this situation in pig houses, is surgical castration at an early age in male piglets, but this practice has shown disadvantages related to the welfare and productive efficiency of the animals. For this study, 60 Camborough (♀C22 X ♂PB380) boars were used under normal conditions of a commercial pig house, and they were put into 3 separated groups: surgically castrated pigs, pigs immunized against GnRH with commercial formulation Improvac® (Zoetis Ltda) and a group of immunized pigs with the experimental vaccine formulation GnRXG/Q. Anti GnRXG/Q antibody titles, testosterone levels and testicular diameter were monitored at different times post immunization. The study showed that both vaccine formulations are effective when it comes to produce immunocastration on male swine, obtaining the productive advantages of maintaining the male entire for a longer period of time, using its anabolic potential, resulting as well in a better alternative for the animals’ welfare....

Doggo : andador canino colapsable para perros de raza pequeña con parálisis de tren posterior
(Universidad de Chile, 2020)
pasar desapercibida. Gran parte de esos animales suelen ser abandonados o incluso sacrificados debido a la desinformación y, sobre todo, por el “sacrificio” energético y económico que puede significar tener un animal con este tipo de discapacidades para...
Doggo is a canine prosthesis designed to contribute to the animal welfare of small breed dogs with some degree of paralysis in their hind limbs. In Chile, although no records are found, animal disability exists and seems to go unnoticed. A large part of these animals are usually abandoned or even slaughtered due to misinformation and, above all, due to the energetic and economic “sacrifice” that having an animal with this type of disability can mean for people. The orthopedic carts on the market only satisfy the need for movement, which does not seem to be enough if the users are beings full of energy who do not perceive physical disability as a limitation. In addition to this, the production of custom-made appliances uses processes that delay delivery to customers, especially in a country where manufacturers are scarce. It is here where a design opportunity is identified that results in the development of a prototype carriage-type prosthesis whose components work dynamically allowing the dog to adopt a resting position without removing the device. The study subject is Lucas, a 4-year-old poodle with partial paralysis caused by an accident. Through digital manufacturing it is also possible to explore the possibility of creating an object with high aesthetic value for animal lovers, who operate in a world and market where custom design is rapidly gaining ground....
