    The cumulative effect of co-infections between pathogen pairs on the haematological response of East African Short-horn Zebu calves is described. Using a longitudinal study design a stratified clustered random sample of ...
  • A live weight–heart girth relationship for accurate dosing of east African shorthorn zebu cattle 
    Lesosky, Maia; Dumas, Sarah; Conradie, Ilana; Handel, Ian Graham; Jennings, Amy; Thumbi, Samuel Mwangi; Toye, Philip G.; Bronsvoort, Barend Mark de Clare (Springer, 2013)
    The accurate estimation of livestock weights is important for many aspects of livestock management including nutrition, production and appropriate dosing of pharmaceuticals. Subtherapeutic dosing has been shown to ...
