Effect of Black Pepper and Jaggery Supplementation with or without Feed Restriction on Broilers Performance

A study was conducted to study the effects of black pepper and jaggery supplementation with or without feed restrictions on growth performance of broilers. In this growth study, 480 chicks were distributed randomly into 8 treatments having total 60 birds per treatment (4 replicates × 15 chicks in each replicate). (T_1- Control group fed ad-libitum as per ICAR specification T₂-T₁ with feed restriction (8–10 hrs) T₃-T₁ with 0.5% black pepper supplementation T₄-T₁ with 0.5% black pepper supplementation with feed restriction (8–10 hrs) T₅-T₁ with 1% jaggery supplementation T₆-T₁ with 1% jaggery supplementation with feed restriction (8–10 hrs) T₇-T₁ with 0.5% black pepper and 1% jaggery supplementation T₈-T₁ with 0.5% black pepper and 1% jaggery supplementation with feed restriction (8–10 hrs). Due to feed restriction significant decrease in average body weight gain was observed at 2^nd week of age but lower feed intake was observed during 2^nd and 4^th week. Black pepper supplementation decreased the average body weight gain at 2^nd week of age and feed intake at 2^nd and 3^rd week of age but there was no significant difference in FCR. No Significant difference in average body weight gain and average feed intake was observed except during 5^th week of age at which both average body weight gain and average feed intake reduced but no significant difference in FCR observed due to jaggery supplementation. So, it was concluded that significant reduction in average feed intake and average body weight gain was observed due to feed restriction.
