La presente investigación se llevó a cabo en el departamento de Huánuco con el Objetivo de Determinar la frecuencia y los factores de riesgo asociados a la contaminación por Salmonella y Staphylococcus aureus en las principales carnes que se comercializan en los mercados de Huánuco. Métodos. Se recolecto 120 muestras de carnes que se comercializan en los principales mercados de Huánuco: M. modelo, M. antiguo y M. de Paucarbamba, el análisis de laboratorio de las muestras se realizó en el laboratorio de Microbiología de la Facultad de Medicina Veterinaria y Zootecnia de la UNHEVAL. Resultados. La frecuencia de Salmonella en los principales mercados de Huánuco fue del 5% y las muestras libres de salmonella fue del 95%. (P=0.005). Las muestras contaminadas con Salmonella en las principales carnes de Huánuco fueron de (6/120), es decir 6 muestras de las 120 muestras analizadas es...

The present investigation was carried out in the department of Huánuco with the objective to determine the fre- quency and risk factors associated with contamination by Salmonella and Staphylococcus aureus in the main meats sold in the markets of Huánuco. 120 samples of meat were collected and sold in the main markets of Huánuco: M. modelo, M. antiguo and M. de Paucarbamba, laboratory analysis of the samples was carried out in the Microbiology laboratory of the Faculty of Veterinary Medicine and Zootechnics of the UNHEVAL. The frequency of Salmonella in the main markets of Huánuco was 5% and the samples free of Salmonella was 95%. (P = 0.005). The samples contaminated with Salmonella in the main meat of Huánuco were of (6/120), that is to say 6 samples of the 120 samples analyzed were contaminated with salmonella and therefore they are considered unfit for its consumption.

In order to obtain an estimate of the nematosis sheep in the Huanuco region, took a nonrandom sample of sheep for slaughter from areas adjacent to the municipal slaughterhouse of Huanuco, considering the month, sex, age, type or breed of animal, season and gender of the parasite. The determination was made by examining parasites fecal samples subjected to sedimentation / flotation of Zn sulfate. The annual prevalence was 73.9%, being higher in the months of March to June and September to October, corresponding to the rainy season and lower during the months of July and August, when the season correponden summer. No significant differences between sexes or age. The number of parasite genera was higher in the month of September.

En diez conejas de la raza Leonado de Borgoña se observó el tamaño de la camada (TC) y el peso promedio al destete por camada (PD) con la finalidad determinar la repetibilidad de estos dos parámetros, evaluando tres partos consecutivos y analizados con el análisis de varianza. Los valores estimados de TC y PD fueron 0,26 y 0,46 respectivamente. Estas determinaciones pueden ser útiles para la selección de reproductores.

In ten rabbits of race Leonado of Burgundy was the litter size (CT) and the average weight per litter at weaning (PD) to determine the repeatability of these two parameters, evaluating three consecutive deliveries and analyzed with analysis variance. The estimated values of TC and PD were 0.26 and 0.46 respectively. These findings may be useful for the selection of players.
