Genetic effects from an Afrikaner, Bonsmara, and Nguni three-breed diallel and top-crosses of Angus and Simmental sires

  • 2020
  • Issue: 3
  • Volume: 50
G.M. Pyoos, M.M. Scholtz, M.D. MacNeil, A. Theunissen & F.W.C. Neser Page: 366 - 377

Individual and maternal breed additive effects and heterosis exist for most economically important traits in cattle. Crossbreeding may therefore be valuable for emerging and commercial beef farmers in improving the productivity of their herds. Calves were produced by mating Afrikaner,…

Antibiotic-free diet supplemented with live yeasts decreases inflammatory markers in the ileum of weaned piglets

  • 2020
  • Issue: 3
  • Volume: 50
S. Bautista-Marín, K. Escobar-García, C. Molina-Aguilar, G. Mariscal-Landín, A. Aguilera-Barreyro, M. Díaz-Muñoz & T.C. Reis de Souza Page: 353 - 365

Emerging bacterial resistance to antibiotics increases the need for effective alternatives to control intestinal inflammation and thus gut disorders in piglets. This study evaluated the effects of including Saccharomyces cerevisiae (strain 1026) and Saccharomyces boulardii (CNCM I-1079) as antibiotic alternatives…
