Abstract

An experiment was conducted to study the effect of Prosopis juliflora seed (PJS) on performance. Based on a randomized completely design, 160 day old Ross 308 broilers were distributed to 16 floor pens and reared for 42 days. Treatments included: 0, 2, 4 and 6% PJ. Feed intake (FI), BW gain (BWG), and feed conversion ratio (FCR) were measured weekly during starter (1 to 21 d) and growing (22 to 42 d) periods. The PJS used in this study contained 90% DM, 12% CP, 7% EE, 22% CF, 0.6% Ca, 0.16% P, 4% ash and 5% tannin. The supplementation of PJS to broiler diets up to 2% had no significant effect on FI in all periods. But treatments containing 4 and 6% PJS had significant lower FI in starter and entire experimental periods when compared to control treatment. BWG of treatment containing 6% PJS significantly decreased in comparison to those of other supplementation levels in starter period.
