Effect of the Use of Phosphoric and Formic Acids in Oral Solution on Laying Performance, Economics and Egg Quality of Japanese Quail (Coturnix japonica)

Résumé fourni par la source

This study aims to evaluate the effects of acids on Japanese quail. 600 females of quails were divided into acidic batch and control batch. The quails from the acidic group received drinking water supplemented with 1% phosphoric acid and 2% formic acid while those from the control group received drinking water without acidifiers. Laying performance, economic performance and egg quality were evaluated. The results show that the laying rate of quails from the acidic batch (76.9 ± 0.3%) is higher than that from the control batch (64.5 ± 0.8%) (p ˂ 0.05). The conversion index is lower (4.2 ± 0.02) for the acidic batch. The acids made it possible to obtain an additional gain of 45100 F CFA. Excepted Haugh units and average egg weight, no significant differences were revealed on other egg quality parameters (p > 0.05). The supplementing drinking water with 1% phosphoric acid and 2% formic acid is a way to improve the performance production of the quail.
