The objective of this study was to evaluate the effect of two microbial preparations on the productive performance, health and blood profile of piglets. In total, 120 piglets (Duroc x Yorkshire/Landrace) offspring of 12 breeding sows (Landrace/Yorkshire) were distributed in three groups of 40 animals each under a completely randomized design: control (T1); Bioprepared (T2) and Biopreparared (T3). T2 contained Lactobacillus acidophilus and Streptoccus thermophilus and T3 Saccharomyces cerevisiae and Kluyveromyces fragilis (L-4 UCLV). Birth weight and body weight and body weight gain (BWG) on days 14 and 33 (weaning) of age, incidence of diarrhoea and blood and biochemical profiles were evaluated. The birth weight and the BWG of piglets of T2 and T3 was greater than in the piglets of the control group (p<0.05), without difference between T2 and T3. The occurrence of diarrhoea was reduce...

El objetivo del estudio fue evaluar el efecto de dos preparados microbianos en el comportamiento productivo, salud y perfil hematoquímico de lechones. Se emplearon 120 lechones (Duroc x Yorkshire/Landrace), crías de 12 cerdas reproductoras (Landrace/Yorkshire), que fueron distribuidos en tres grupos de 40 animales cada uno bajo un diseño completamente aleatorizado: control (T1); Biopreparado (T2) y Biopreparado (T3). El T2 contenía Lactobacillus acidophilus y Streptoccus thermophilus y T3 Saccharomyces cerevisiae y Kluyveromyces fragilis (L-4 UCLV). Se evaluó el peso al nacer, y el peso y ganancia de peso (GPV) en los días 14 y 33 (destete) de edad, así como la incidencia de diarreas, perfiles hemáticos y bioquímica sanguínea. El peso al nacer y la GPV de los lechones de T2 y T3 fue mayor que en los lechones del grupo control (p<0.05), sin variación entre T2 y T3. La ocurre...

A descriptive study was conducted with the aim to evaluate the effectiveness of the combination of surgical and chemotherapeutic treatment in transmissible venereal tumor (TVT) in canines. The study was carried out with cases brought to consultation in the veterinary clinic of the municipality of Rodas, Cienfuegos Province, Cuba. The population studied was 57 dogs diagnosed with TVT. One group (n=14) received chemotherapy with vincristine sulfate (00.1 mg/kg intravenously, three times at 10-day interval), a second group (n=17) underwent surgical treatment and the rest (n=26) received initial surgical treatment followed by chemotherapy, with the same dose and concentration as the first group. The results showed that the combination of surgery and chemotherapy obtained the total recovery of the animal in 95% of the cases in a period of three months.

Se realizó un estudio descriptivo con el objetivo de evaluar la efectividad de la combinación del tratamiento quirúrgico y quimioterapéutico en el tumor venéreo transmisible (TVT) en caninos. El estudio se realizó con casos llevados a consulta en la clínica veterinaria del municipio de Rodas, Provincia Cienfuegos, Cuba. La población estudiada fue de 57 perros diagnosticados con TVT. Un grupo (n=14) recibió quimioterapia con sulfato de vincristina (0.01 mg/kg, vía endovenosa, tres veces con intervalos de 10 días), un segundo grupo (n=17) fue sometido a tratamiento quirúrgico y el resto (n=26) recibió tratamiento quirúrgico inicial seguido de la quimioterapia, con la misma dosis y concentración que el primer grupo. Los resultados demuestran que la combinación de la cirugía y quimioterapia resultó en la total recuperación de los animales en el 95% de los casos en un perio...

El objetivo de la investigación fue determinar la evolución histórica y los canales enzoóticos de la seroprevalencia del virus de la enfermedad de Newcastle (VENC) en dos granjas de patos Pekín de la provincia Artemisa, Cuba. Se realizó un estudio epidemiológico observacional retrospectivo de la seroprevalencia del virus, basado en el diagnóstico serológico de una serie de tiempo de cinco años. Se determinó si la época del año constituía un factor de riesgo asociado a la seroprevalencia. Fueron definidos los canales enzoóticos de la seropositividad y medias geométricas del virus. Se evidenció mayor riesgo de seroprevalencia al VENC, con incremento a medida que transcurrieron los años. Los valores de las medias geométricas de los títulos de anticuerpos contra el virus estuvieron por encima del comportamiento habitual o canal enzoótico, en zonas de alerta y epizoótica...

The mite Varroa destructor Delfinado & Baker, 1974 is the most serious pest of honey bee colonies worldwide. This species has become a major plague for world beekeeping of European bees (Apis mellifera Linnaeus, 1758), although the impact from mite infestations varies greatly between continents. The objective of this study was to calculate the risk for varroosis after the application, individually and jointly, of three methods: honeycomb trap, queen replacement and best practices; as well as to assess the economic losses in the province of Villa Clara, Cuba. A total of 467 apiaries were investigated, three hives were sampled per apiary, for a sample size of 3,257 individuals. A retrospective descriptive epidemiological analysis of the behavior of the occurrence of varroosis was carried out. A chronological series of three years was analyzed and the seasonality, channels of habitual b...
