      Brand, Z.; Cloete, S. W. P. (Schalk Willem Petrus van der Merwe); Malecki, I. A.; Brown, C. R. (South African Society for Animal Science, 2016-12-06)
      The patterns of embryonic development in ostriches, especially in the last stage of hatching, are still not well understood. This study examined between 3468 and 3484 dead-in-shell (DIS) eggs with chicks that died between ...
    • Foster parenting, human imprinting and conventional handling affects survival and early weight of ostrich chicks 

      Wang, M. D.; Cloete, S. W. P. (Schalk Willem Petrus van der Merwe); Bonato, M.; Dzama, K.; Malecki, I. A. (South African Society for Animal Science, 2012)
      The effects of human imprinting and foster parenting by adult ostriches on the survival and growth performance of ostrich chicks were compared to conventional chick-rearing practices in two separate experiments. In the ...
    • Genetic parameters for ostrich incubation traits in South Africa 

      Brand, Z.; Cloete, S. W. P. (Schalk Willem Petrus van der Merwe); Malecki, I. A.; Brown, C. R. (South African Society for Animal Science, 2009)
      Data obtained from a pair-mated ostrich flock located at Oudtshoorn, South Africa, were used to estimate genetic parameters for egg weight (EWT), weight of day-old chicks (CWT), water loss to 21 (WL21) and 35 (WL35) days ...
    • Meat quality, skin damage and reproductive performance of ostriches exposed to extensive human presence and interactions at an early age 

      Muvhali, P. T.; Bonato, M.; Engelbrecht, A.; Malecki, I. A.; Mapiye, C.; Cloete, S. W. P. (Schalk Willem Petrus van der Merwe) (Springer, 2020)
      The effect human presence and interactions performed after hatch to 3 months of age has on ostrich meat quality, skin damage and reproductive performance at a later age was investigated in 416-day-old ostrich chicks. The ...
    • Ostrich ejaculate characteristics and male libido around equinox and solstice dates 

      Muvhali, P. T.; Bonato, M.; Malecki, I. A.; Du Plessis, L.; Soley, J. T.; Cloete, S. W. P. (Schalk Willem Petrus van der Merwe) (Springer, 2020)
      The study evaluated the effect of time of the year in which changes in photoperiod occurs on ostrich semen characteristics and male libido. Semen was collected for 5 days before, on and 5 days after winter solstice (21 ...
    • Sperm storage and duration of fertility in female ostriches (Struthio camelus) 

      Malecki, I. A.; Cloete, S. W. P. (Schalk Willem Petrus van der Merwe); Gertenbach, W. D.; Martin, G. B. (South African Society for Animal Science, 2004)
      In two experiments, one carried in South Africa and the other in Western Australia, the duration of sperm storage and the fertile period following separation of sexes were investigated by egg break-out and by counting the ...
