Evaluation of Aloe vera (Aloe barbadensis linné) and Ginger (Zingiber officinale) as phytogenic supplements for broilers
… sizes, and meat quality broilers. A total of 480 Ross 308 broilers were housed in a deep litter open-sided house, stocked at 15 birds per 150 cm length × 144 cm width mesh-wire pen. During the starter period (days 1-22), the chicks were fed a diet containing 220 g kg-1 CP and 17.8 MJ ME kg-1. For …
