Abstract
The influence of varying dietary protein and energy levels on the relative growth of body
components of ostriches was evaluated over a 244-day growth period. One hundred twenty
1-day-old ostrich chicks were randomly assigned to 15 pens. Three varying energy regimes
(high, medium and low) and five protein levels (1–5) were supplied ad libitum to each pen. A
randomly selected bird from each pen was slaughtered at 1, 35, 63, 103, 159, 168 and 244 days
of age. Each bird was weighed, stunned, exsanguinated, defeathered and eviscerated.
Individual body components were dissected and weighed at every slaughter age. Proximate
analysis was performed on these components, which were ground with the remainder of the
carcass, excluding gut content, but including blood and feathers.
