The Significance of Dietary Energy for the Production Parameters of Feedlot Ostriches

Authors:Nicholas Russell

Abstract


Energy is essential for the continued survival of any living thing. In ostrich feed, energy usually comes from corn. Due to drought conditions, corn is often affected by fluctuations in production. Therefore, the optimal use of energy in the ostrich diet has become crucial, but it will not negatively affect the performance of poultry. The purpose of this study was to study the effect of five diets (each with different energy concentration) on the growth performance of 300 slaughtered ostriches. Each treatment was repeated three times, resulting in 15 ostrich camps undergoing four stages from pre-starter to starter, and then growing to the final breeding. At the beginning of the chicks, the mortality rate was high. After pre-starter, there was a significant difference between the live weights of poultry, with poultry consuming a medium diet (Diet 3) the heaviest, with an average of 22.3 ± 0.33 kg. However, by the end of the experiment, these differences were not significant. This is reflected in production parameters, namely dry matter intake (DMI), average daily gain (ADG) and feed conversion rate (FCR). The difference was found only in the pre-starter phase of ADG. Diet 3 showed a maximum daily weight gain of 216.0 ± 8.08 g. The high mortality rate experienced during the pre-starter phase of the trial may have contributed to findings that to an extent, contradictory to previous studies that investigated the impact of energy on production of ostriches.
