Title: Efficacy and Safety of Spectinomycin-Lincomycin and A Multivitamin for the Propylactic and Methaphylactic Use In Weanned Piglets Authors: Fuentes Hernández, Víctor Octavio Abstract: Efficacy and safety of spectinomycin-lincomycin added to the starter feed formula for piglets at weaning plus a multivitamin in the drinking wáter for three weeks after weaned piglets was studied. Four groups were used. Groups 1, 2 and 3 development and growth was as expected. Group 2 shows a slight increase in weight, which although not significant, allows postulating that the combination of Spectinomycin-Lyncomycin and polyvitamins can be considered as EFFECTIVE AND SAFE combination to be used in weaned piglets. The control group development was slightly lower, although not significant, the weight of the control group can be considered as a cause of an environmental factor of the intensive exploitation in which the study was developed. Since they were exposed to the presence of endemic infections, a situation that Lincomycin - Spectinomycin have a recognized efficacy to prevent enteropathies. It was concluded that the profilactic and methahylactic use of spectinomycin-Lincomycin in feed plus a polivitamin formulation in drinking wáter is highly recomended. Description: Artículo

Title: Pneumonia bovina: estudio comparativo utilizando antibioticos y nanopartículas de titanio con extractos citricos adsorbidos en su estructura Authors: Fuentes Hernández, Víctor Octavio Abstract: El objetivo de este estudio fue determinar la eficacia ceftiofur y extractos cítricos adsorbidos a nanopartículas de titanio (NANOCIT) durante el tratamiento de vacas lecheras con pneumonía aguda. Vacas (n = 18) en diferentes etapas de producción con diferentes signos de enfermedad respiratoria. Para tratamiento con ceftiofur se escogieron 8 al azar, una murió, dos requirieron tratamiento doble, se considera que los animales que requirieron repetición de tratamiento con ceftiofur probablemente estaban afectados por cepas virales no susceptibles al antibiótico. Los animales tratados con NANOCIT presentaron una respuesta de recuperación rápida después de recibir dos dosis intravenosas de 50 cc de NANOCIT, se puede postular que esta alternativa terapeútica para el tratamiento de la pneumonia bovina debe considerarse como importante para disminuir el uso de antibióticos.

Title: Mating Behavior of White New Zealand Rabbit Does. Effect of an Opioid Antagonist. Authors: Fuentes Hernández, Víctor Octavio Abstract: Abstract: When does are taken to mate some are ready for mounting, while others show lordosis, cornering and circling. Naloxone treated does were notably calm during handling and mating and behavioral scores were lower compared with saline treated does (P=<0.05It It was concluded that the endogenous opioid system in White New Zealand rabbit does, facilitate sexual behavior and reproduction.

Nursing Behaviour of White New Zealand Rabbit Does. Effect of an Opioid Antagonist

2022-06-15T18:39:45Z

Title: Nursing Behaviour of White New Zealand Rabbit Does. Effect of an Opioid Antagonist Authors: Fuentes Hernández, Víctor Octavio Abstract: ABSTRACT: A group of does (n = 10) received 0.5 mg NX at 12 hr. intervals two days before and two days after mating, a control group (n = 10) was sham treated with saline injections. After kindling, kints born, nursing time and kint growth was studied. NX treated does nursed their kints for 235 ± 11.3 secs vs controls 220 ±16.2 secs (P<0.05). Milk yield and Kint weight was significantly higher in naloxone treated does.Kints born from control and naloxone treated does was 10.1  1.1 and 12.13  0.77 (P<0.05). Kints born live from naloxone treated and control dams was 11.3  0.94 and 9.5  0.9 (P<0.05). NX treated does weaned 10.0  0.9 kints, controls 8.7  1.05 (P<0.05). It was concluded that endogenous opioids are important modulators of nursing behavior in rabbit does favoring the development of their young. Description: Artículo
