Effect of feeding systems and phytase supplementation on the performance of broiler chicks during summer season
Abstract: The objective of the study was to evaluate the effect of four different feeding systems of feed supplemented with or without 750 FTU microbial phytase/kg diet from 7-42 days of age during summer season. First and second systems were based on skip a day and skip a half day (12hr feed +12hr fast) respectively. The third system feeding the actual requirement of protein and energy while the last system was depend upon ad libitum and used as a control group.
A total number of 240 one day unsexed Arbor broiler chicks were used in this study. At the 7th day of age, birds were distributed into 8 experimental treatments in (2x4) factorial design. Results of starting-growing period (2-3 weeks of age) indicated that either phytase supplementation or the fourth feeding system (ad libitum) improved significantly (P<0.01) the all performance parameters. While during finisher period (4-6 weeks of age) the feeding systems effects was negectable in comparison with phytase supplementation effects which still has the same role of an improvement during finisher period. The over all results showed that the interaction either between the second or third feeding system with phytase supplementation significantly (P<0.05) improved the performance parameters and economical efficiency.
