The hypothesis was that owing to their high bioavailability, zinc oxide nanoparticles (NanoZnO) can effectively replace (Zn) salts and reduce Zn excretion with faeces. The objective of this study was to investigate the effects of NanoZnO on the development of…
This study describes changes occurring in the live weight and body composition of male and female South African Black ostriches over a growing period of 285 days. Forty-five birds were given four diets with different protein (ca. 180 and ca…
A study was conducted to describe the changes occurring in body composition of ostriches over a 285-day growth period. Fifty two birds were given a choice of four diets with different protein (180 and 120 g/kg feed) and energy (8.5…
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 of incubation, and pipping…
