• 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) ...
    • 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 ...
