l-carnitine is a potent antioxidant used for in vitro culture systems. Controversial results have been reported using medium at different stages of bovine embryo production. Cumulus-oocyte complexes (n = 843) were vitro-fertilized and cultured added (treatment group) or not (control with l-carnitine. At day three culture, each group was subdivided into two subgroups receiving no (group 1), 3.8 mM during maturation 2), 1.5 the 3), respectively 4). 8, blastocyst embryos examined mitochondrial...
El objetivo de este trabajo fue caracterizar el semen individuos ovinos criollos colombianos pelo en la granja Universidad Sucre. estudio se llevó a cabo “El Perico” Sucre, 50 msnm, clima cálido seco y con formación vegetal bosque tropical. Se utilizaron cuatro adultos, no emparentados, los cuales fueron colectados veces intervalos cinco días, mediante técnica electroeyaculación evaluaron las características seminales macroscópicas microscópicas. encontró que color predominante es blanco...
The objective of this work was to determine the frequency bacteriospermia and its effect on seminal quality in canines. Dogs were divided into two groups according weight: small dogs between 1 10 kg (Group 1) with more than 2). foreskin disinfected each animal (n=15), semen sample collected by gloved hand method. Sperm motility, morphology, viability, concentration evaluated using a 40x microscope. A 10µL drop cultured diffusion method blood agar MacConkey agar. Colony-forming units (CFU)...
Objective: The objective of this study was to associate the 1016G > A variant melanocortin-4 receptor gene with lamb’s weight, growth, and meat quality in Colombian hair sheep breed. Materials Methods: total 168 lambs, weights were measured at birth weight (BW), weaning adjusted (AWW), 6 months [adjusted (AW180)], slaughter (ASW), daily gain preweaning (preWDG), postweaning (postWDG) weaning, after slaughter, pH, texture, cook-loss (CL) longissimus thoracis et lumborum (LTL) muscle...
The achievement of education in rural populations was one the Millennium Development Goals (MDGs), outlined by United Nations. During last World Summit on Sustainable (WSSD), it concluded that majority world’s poor, illiterate and undernourished population lives areas; therefore, access to is considered greatest challenges for governments countries with developing economies. purpose this study determine how a theoretical-practical training program management leadership (D-ML), artificial...
The bovine leukosis virus causes enzootic (BLV) of the Retroviridae family and is most significant neoplastic disease in cattle, leading to substantial economic losses globally. This study aimed associate progression with BoLA-DRB3 alleles Lucerna breed. A total 104 animals were tested for presence BLV by nested PCR, development persistent lymphocytosis (PL) peripheral blood smear, antibody titers (AT) ELISA, proviral load (PVL) qPCR. Animals genotyped gene PCR-SBT. Allele frequencies DRB3...
Artificial insemination (AI) is considered as the most efficient feasible tool to improve dairy cows’ profitability and productivity. In bovines, AI helps promote genetic improvement can positively impact rural economy. The achievement of education in populations was one Millennium Development Goals (MDGs), made by United Nations. During last World Summit on Sustainable (WSSD), it concluded that world’s poor, illiterate undernourished population lives areas; therefore,...
El sistema de producción porcina en Colombia, ha tenido un gran crecimiento los últimos años, gracias a la implementación técnicas como inseminación artificial, cual permite realizar mejoramiento genético incrementando productividad. Sin embargo, el modelo manejo reproductores y donantes semen no es adecuado, siendo mantenidos confinamiento, alimentados con dietas que suplen requerimientos micronutrientes (Zn Se) alterando calidad seminal. Por lo anterior, se han propuesto modelos...

El objetivo del estudio fue evaluar el efecto YM976 como inhibidor específico de la fosfodiesterasa tipo 4 (PDE-4) sobre maduración in vitro oocitos bovinos y su capacidad desarrollo embrionario. Para ello, complejos cúmulo-oocito se obtuvieron por aspiración folicular ovarios obtenidos en planta sacrificio. Se maduraron 24 horas medio TCM-199 suplementado con cuatro concentraciones (1, 10, 100 1000 nM) o gonadotropinas (LH FSH). evaluó expansión cúmulo observación visual reanudación...
Se evaluó el efecto de la adición diferentes concentraciones un suplemento mineral, sobre calidad seminal en cerdos machos adultos usados para reproducción. El ensayo se realizó municipio Sincelejo. experimento constó tres ciclos suplementación donde suministraron 10, 20 y 30 g/día cada cerdo por ciclo. Cada ciclo duró 55 días, obtuvo 1 eyaculado/cerdo/semana (10 eyaculados/ciclo). Las colectas seminales fueron realizadas con método mano enguantada. Posterior a colecta, semen fue...
El objetivo de este trabajo fue aplicar la metodología criopreservación semen canino en pajilla francesa el municipio Medellín- Antioquia. Se realizó una colecta seminal a ocho caninos adultos, por método mano enguantada, cada eyaculado evaluado macroscópica y microscópicamente posteriormente diluido con Triladyl® concentración final 80 x 106 espermatozoides/ml. empacaron pajillas 0,5 ml fueron sometidas un descenso temperatura rápido, sometiendo las vapores nitrógeno durante 25 minutos...
This case report describes azoospermia in a French bulldog. The dog, with historical evidence of unsuccessful insemination after both artificial and natural breeding, presented physiological parameters (testosterone levels karyotype) within normal ranges. Scrotal palpation ultrasound testicles indicated aplasia the epididymis vas deferens. Two seminal samples were examined no sperm cells found. In conclusion, before starting an assisted reproduction procedure, it is necessary to perform...
Objetivo. Estimar la diversidad morfométrica, faneróptica y de cuatro genes dominantes en aves criollas pescuezo desnudo (Gallus domesticus L. Subespecie nudicollis) traspatio subregión Sabana, departamento Sucre (Colombia). Materiales métodos. En 650 adultas (480 gallinas 170 gallos) 10 localidades, se midieron 14 variables morfométricas, ocho fanerópticas dominantes. Los datos fueron sometidos a análisis descriptivos. Mediante análsis varianza test Ducan compararon las entre localidades....
Es posible que el asno criollo colombiano (ACC) se encuentre en peligro de extinción. La alarmante disminución su inventario está reduciendo la diversidad genética. Así, caracterización morfológica es un primer paso futuros planes conservación, con objetivo repoblación; por tanto, esta investigación fue caracterizar zoométricamente y etnológicamente ACC, las cinco subregiones naturales del departamento Sucre. En 20 machos cada una Sucre (Golfo Morrosquillo: GM, Montes María: MM, Mojana: MO,...
