NM 24. Use of sweet potato meal (Ipomea batas (L) Lam) as energy source in the layin diet of japanese quail

Abstract

With the purpose of evaluating the effect of substituting Zea mays meal (MZM) for root sweet potato meal (MRSP) in the laying diet of japanese quail, a complete remdomized design was used to evaluate 5 treatment where substitution level were 0, 25, 50, 75, 100%Each treatment had 24 japanese quail, 9-week old. Variables evaluated were feed consumption (FC), egg weight (WE), feed utilization efficiency (EFU), internal egg quality (IQ Haugh units), during 5 periods of 15 days of egg production (EP). No significant differences (P<.05) were observed for WE, IQ, and EP. Significant differences were found on FC with 23, 24, 26, y 27 g of FC for 00, 25, 50, 75, and 100 % energy substitution, respectively. For EFU, significant differences were determined (P<.05) with values of 33.4, 32.8, 37.7, 36.2, 38.4 for 00, 25, 50, 75, and 100% of substitution. These results suggest that substitution of 75% of energy included in quail layer diet with MRSP can be made.
