  • Bromide : a potential risk to livestock production in South Africa 
    Casey, Norman Henry; Lucht, Heike Luise; Reijnders, B. (South African Society for Animal Science, 2019)
    Bromide (Br-) concentrations (mg/L) in groundwater range from no observed adverse effect levels (NOAEL), which is considered safe, and increase to constituent of concern (COC) when the concentrations approach the recommended ...
  • First parity productivity of selected commercial sows 
    Lucht, Heike Luise (University of Pretoria, 2010-09-09)
    This study analysed first parity productivity records over a determined time period of three years from two selected commercial pig production units on the Highveld, and determined whether seasonal differences in ...
  • Growth and development responses of Gallus gallus domesticus embryos to in ovo bromide exposure 
    Lucht, Heike Luise (University of Pretoria, 2020)
    Collated data showed that the concentration range of bromide (Br-) in groundwater (GW) was between 0 – 132mg/L in selected provinces in South Africa where livestock production occurs. The no observed adverse effects level ...
  • Prevalence of bromide in groundwater in selected regions in South Africa 
    Lucht, Heike Luise; Casey, Norman Henry (Water Research Commission, 2019)
    Many regions across South Africa are dependent on groundwater as the only water source for livestock watering and domestic use. This paper presents an analysis of 350 water samples from collated data of 5 reports published ...
  • Survival and development of embryos of Gallus gallus domesticus treated with inorganic bromide 
    Lucht, Heike Luise; Casey, Norman Henry; Sawosz, E. (South African Society for Animal Science, 2018-07-05)
    The range of bromide (Br-) in groundwater sources surveyed in South Africa is 0 - 18.4 mg/L. The research aimed to establish chicken embryo sensitivity to a range of Br- treatments (mg/L) injected into fertilised Ross-308 ...
