ABSTRACT.
Thirty Holstein calves were assigned to the following treatments groups: T1=bulls (n=10); T2=cryptorchids (n=10) and T3=steers (n=10). All animals had an initial liveweight (LW) of 150±21 kg fed with the same diet based on an oversown pasture grazed at 5% of LW and at 2.5% LW+supplementation at 1% LW using entire corn grain (winter). Information of carcass yield and meat quality was recorded. Daily live weight gain presented differences amongst treatments, being T1=T2> T3 (P<0.01). Higher values of hot carcass weights and carcass yield were observed (P<0.01) in T1 and T2 compared with T3. There was a significant effect (P<0.01) of the animal gender in main cuts (striploin, tenderloin, sirloin and outside flat) weights, being higher (P<0.01) for T1 and T2 compared with T3, and also in most of each cuts weights measured. The results on meat quality traits show that marbling values and fat colour where higher for T3 (P>0.01). For muscle colour, no differences were found among treatments, but a trend of lower values was observed (P<0.05) for T1 (less brightness, red level and yellowing). These results suggest that in Holstein beef production systems, gender could play an important role to improve productivity and carcass traits. |

ABSTRACT. Records of in vitro susceptibility tests performed between 2008 and 2015 were retrospectively reviewed in order to evaluate the dynamic profiles of possible changes in antimicrobial resistance of Staphylococcus aureus isolated from milk samples of cows with subclinical mastitis from 12 different Uruguayan Provinces. The results of 1,631 isolates tested by disk diffusion technique for susceptibility to penicillin and erythromycin were analysed. The possible tendency or changes in the behaviour of this pathogen against penicillin and erythromycin in the 8 year period was evaluated using the chi-square tests for trend and the homogeneity. The highest rate of resistance was observed for penicillin (36.9% in 2010), while erythromycin showed a resistance rate significantly lower (5.7% in 2015). The test for trend showed a significant trend towards decreased resistance to penicillin, whereas for erythromycin an increased resistance trend was observed. The determination of the scope of the problem is essential for the formulation and monitoring of effective response to anti-microbial resistance (AMR). Antibiotic assessment in Uruguay is now being reviewed with the objective of limiting antibiotics prescription to professionals trained to select a successful therapy, choosing the appropriated drug and treatment duration according each situation. To generate knowledge on the magnitude and tendency of the AMR problem using country-specific information must be a priority.
RESUMEN. Los registros de las pruebas de susceptibilidad in vitro realizadas entre 2008 y 2015 fueron revisados retrospectivamente con el fin de evaluar los perfiles dinámicos de posibles cambios en la resistencia antimicrobiana de Staphylococcus aureus aislados de muestras de leche de vacas con mastitis subclínica de 12 provincias uruguayas. Se analizaron los resultados de 1.631 aislamientos mediante la técnica de difusión en disco para la susceptibilidad a penicilina y eritromicina. La posible tendencia o cambios en el comportamiento de este patógeno frente a la penicilina y la eritromicina en el período de ocho años se evaluó utilizando las pruebas de chi-cuadrado para la tendencia y la homogeneidad. La mayor tasa de resistencia se observó para penicilina (36,9% en 2010), mientras que eritromicina mostró una tasa de resistencia significativamente menor (5,7% en 2015). El resultado de la prueba de tendencia fue significativo, indicando una disminución de la resistencia a la penicilina, mientras que para la eritromicina se observó una tendencia a aumentar la resistencia. Determinar el alcance del problema es esencial para la formulación y el seguimiento de la respuesta eficaz a la resistencia antimicrobiana (RAM). La evaluación de antibióticos en Uruuguay está siendo revisada con el objetivo de limitar la prescripción de antibióticos a los profesionales capacitados para seleccionar una terapia exitosa eligiendo la droga apropiada y la duración del tratamiento de acuerdo con cada situación. Generar conocimientos con información específica del país respecto de la magnitud y las tendencias del problema de RAM debe ser una prioridad. MenosABSTRACT.
