    • 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) ...

    • Nitrate and nitrite metabolism in ruminant livestock 

      Villar, Maria Laura (Edición del Autor, 2019)
      Global methane emissions from livestock have continue to rise in last decade due to the increasing ruminant population and demand for livestock products. Supplementing the diet of ruminants with nitrate (NO3) is an effective ...

    • 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 ...
