Item Análisis de Técnicas De Congelación De Semen Equino Empleadas En La Actualidad. Monografía(Universidad Antonio Nariño) Rangel Núñez, Edison Darío; Bonilla Correal, SebastiánSeminal cryopreservation is a tool that allows the preservation and storage of genetic material for long periods of time, especially of males genetically superior, facilitating the work of artificial insemination since the semen horses have low motility and a high percentage of abnormal sperm cells, In addition to the fact that few stallions respond well to semen freezing, some of the causes of poor response to cryopreservation are the cryoprotectants used, the permeability of the spermatic membrane, the microbial load present in the ejaculate, the genetic factors. Sperm are subjected to different risks in the process of freezing, such as temperature, osmolarity that can cause damage to the structure of the cell membrane and osmotic stress, which generates an increase in cell permeability which leads to the entry of water, ions and cryoprotectants. The purpose of this collection literature is to recognize the different freezing techniques, advances, shortcomings in order to to improve the result that can be obtained after using cryopreservation protocols seminalItem Estudio Retrospectivo Del Porcentaje De Preñez Y Viabilidad De Reabsorción De Embriones En El Criadero La Marqueza Entre 2020 Y 2021(Universidad Antonio Nariño) Otálora Rojas, Kevin Andrés; Pulido Aldana, Juan Esteban; Arévalo Guasca, Edgar Camilo; Bonilla Correal, SebastiánEmbryo transfer is one of the updated techniques currently used throughout the world and which presents an efficiency rate both in the collection of the embryo through washing and the pregnancy rate at the time of carrying out the transfer process. There are multiple reproductive biotechnologies today, where the Veterinary Doctor / Veterinary Doctor and Zootechnician will implement the method where he has obtained the best results.Item Monografía. La mente del gato doméstico : felis silvestris catus(Universidad Antonio Nariño) Montoya Torres, David Ernesto; Medrano Galarza, Catalina; Bonilla Correal, SebastiánThe science of animal welfare holds extensive research in the spheres of physical health and behavioral expression (naturalness), but regarding the mental sphere there is greater complexity and fewer studies, despite being one of the three fundamental pillars of animal welfare. The cat became the favorite pet in much of the world. However, there is a lack of research of this species, and understanding the feline mind is essential to provide adequate welfare conditions. In addition, there is a bidirectional relationship between cognition and welfare and this is a species that requires enriched environments in a more complex and stimulating way. The purpose of this review was to describe the different investigations that have tried to understand the mind of the domestic cat Felis silvestris catus. Cognitive research conducted on cats includes perception, object permanence, memory, physical causality, quantity and time discrimination, sensitivity of cats to human signals, vocal recognition and communication, attachment bonds, personality, and cognitive health; demonstrating in all cases the ability of the cat in these areas. Studies in cognition have demonstrated the ability of the cat to learn, do quickly and modify his behavior after learning, which also allows us to assume some degree of consciousness. The sentience of the cat is demonstrated by his ability to experience negative (fear and pain) and positive (joy, "friendship") emotions. The cat's mind is unique and it is extremely important to use some methods and interpret results in the context of the species. We can conclude that scientific research to date shows the capacities of sentience and cognition of the domestic cat, and opens the window for further research on the feline mind and its repercussions on maximizing its level of welfare and granting the protection they deserve.
