| Abstract | ||||
| A total number of 224 one-day old Japanese quail chicks were distributed into 7 groups of 4 replicates of 8 chicks each (7x4x8 ) and reared under similar management ,conditions up to 6 weeks of age in electrically heated quail batteries. Seven growing diets were formulated in which the first one was corn-soybean diet and taken as a control (T1). In the other diets, 50% of corn in T1 was replaced by either tapioca (T2), or crushed macaroni only (T3). All corn in T1 was replaced (100%) by either 1:1 tapioca+crushed macaroni (T4), tapioca only (T5), crushed macaroni only (-16), or a mixture (1:1:1) of corn + tapioca + crushed macaroni (T7). All diets were nearly iso-nitrogenous of about 24% CP and iso-caloric of about 3000 Kcal ME/Kg and adjusted to satisfy nutrient requirements of quails. The results obtained showed that T7 in which corn, tapioca and crushed macaroni (1:1:1) replaced corn in T1, gave the best values of growth performance in term of live body weight, weight gain, feed consumption, feed conversion and percentage od carcass yield, followed by T6, T3, T4, T1, 12 and T5 which resulted in the lowest values. Generally, it could be concluded that, for feeding Japanese quails from 0 to 6 weeks of age (the marketing age), crushed macaroni can successfully replace yellow corn up to 100%, while, tapioca can safely be used up to 50% of yellow corn in diets as untraditional sources of energy without any adverse effect on growth performance or carcass characteristics. In other words, crushed macaroni and tapioca can be considered as suitable sources of energy for feeding growing quail chicks. | ||||
