Growth performance of young ostriches (Struthio camelus)

Abstracts

The growth performance of young ostriches and emus was studied in two ratite farms, A and B, in Saudi Arabia. Both ostrich and emu chicks showed little weight gain in the first few days of life compared to the following days which showed non-stable and nonconsistent body weight gain. The fluctuation in weight gain in emu chicks was less remarkable compared to that in ostrich chicks. The growth rate of ostrich chicks in Farm B at the end of the first 14 weeks of life was better and faster than that of ostrich chicks in Farm A at the same age period. The growth rate of ostrich chicks hatched during the summer period was found to be faster, more stable and less fluctuating than that of the chicks hatched during the winter period which, also, had a net negative weight gain by the 10th week of the observation period.
