ABSTRACT
As part of the search for alternatives to pharmaceutical products used to improve poultry productivity, several alternative methods are increasingly proposed such as the use of plant extracts. Thus, the aimof the present study wasto evaluate the effect of adding aqueous extract from leaves of Sclerocarya birrea to water, on the zootechnical performance of broilers. A total of 300 one-day-old chickens were randomly distributed into three experimental batches of 100 chicks each. The control group chickens (Lot A) were provided with drinking water without the addition of leaves extract of S. birrea. Lots B and C had accessto water containing respectively 5 g/L and 10g/L of aqueous extract of leaves of S. birrea. Throughout the experiment, weight growth, weight gain, consumption index and mortality rate were recorded once a week during four (4) weeks, The results obtained showed that chickens having received aqueous extract of leaves of S. birrea have the highest live weights with a consumption index and the lowest mortality rate. In addition, chickens having received 10g/L of extract record the best zootechnical performances. Under the present experimental conditions, the addition of aqueous extract of leaves of S. birreato drinking water had a positive impact on the zootechnical performances of broilers chickens.
