    • Corynebacterium pseudotuberculosis biovar ovis: evaluación de la sensibilidad antibiótica in vitro 

      Gallardo, Adriana Alicia; Toledo, Rocío Andrea; Gonzalez Pasayo, Ramón Alejandro; de Carvalho Azevedo, Vasco Ariston; Robles, Carlos Alejandro; Paolicchi, Fernando; Estevao Belchior, Silvia Graciela (Asociación Argentina de Microbiología, 2019-12)
      Los objetivos de este trabajo fueron estudiar la sensibilidad antibiótica de aislamientos de Corynebacterium pseudotuberculosis procedentes de pequeños rumiantes e investigar la presencia de integrones que contienen genes ...

    • Dietary nitrate and presence of protozoa increase nitrate and nitrite reduction in the rumen of sheep 

      Villar, Maria Laura; Hegarty, Roger Stephen; Clay, Jonathon William; Smith, Katherine Anne; Godwin, Ian Robert; Nolan, John Vivian (Wiley, 2020-04)
      Nitrate (NO−3) supplementation is an effective methane (CH4) mitigation strategy for ruminants but may produce nitrite (NO−2) toxicity. It has been reported that rumen protozoa have greater ability for NO−3 and NO−2 reduction ...

    • Dietary nitrate metabolism and enteric methane mitigation in sheep consuming a protein-deficient diet 

      Villar, Maria Laura; Hegarty, Roger S.; Van Tol, M.; Godwin, Ian R.; Nolan, John V. (CSIRO Publishing, 2019-09-20)
      It was hypothesised that the inclusion of nitrate(NO3 –) or cysteamine hydrochloride (CSH) in a protein deficient diet (4.8% crude protein; CP) would improve the productivity of sheep while reducing enteric methane (CH4) ...

    • Programas de mejora genética de rumiantes menores basados en comunidades 

      Mueller, Joaquin Pablo (2017)
      A recent revision of the state of knowledge, principles and examples of breeding programs described as community based (CBBP) indicates that such programs typically relate to low-input systems with farmers having a common ...

    • The effects of dietary nitrate on plasma glucose and insulin sensitivity in sheep 

      Villar, Maria Laura; Godwin, Ian R.; Hegarty, Roger S.; Dobos, Robin Christopher; Smith, Katherine A.; Clay, Jonathon W.; Nolan, John V. (Wiley Online Library, 2019-07)
      Nitrate (NO3 ¯) is an effective non‐protein nitrogen source for gut microbes and reduces enteric methane (CH4) production in ruminants. Nitrate is reduced to ammonia by rumen bacteria with nitrite (NO2 ¯) produced as an ...
