Performances de croissance, de ponte et qualité de l’œuf chez la caille Japonaise (Coturnix coturnix japonica)

Abstract

Le présent travail a consisté à étudier les performances de croissance (durant 6 semaines) et de ponte (9ème-12ème semaine) de Coturnix coturnix japonica ainsi que la qualité interne et externe des œufs. Au total, 300 cailleteaux de 1 jour d’âge ont été menés au sol. Á 6 semaines d’âge, le poids vif (PV) moyen a été de 162g avec un indice de consommation de 3,59. Les mensurations effectuées à l’âge de 8 semaines ont montré un dimorphisme sexuel significatif (P

Effect of feed particle size on growth and egg-laying parameters of Japanese quail (Coturnix japonica) in Côte d’Ivoire

“…The best ADG values (AC 2: 6.67 g/d and AP 2: 5.92 g/d) obtained in the present study at week 5 were much higher than those obtained by other authors. This is the case of [2], [18], [21] as well as [25] who respectively obtained 3.91 g/d; 3.41 g/d to 3.65 g/d; 3.69 g/d and 3.64 g/d. ADGs close to those of this study were also obtained by [33], [35] as well as [42].…”

“…At the same age, [23] obtained LWs ranging from 168.2 to 173.8 g in three different varieties of Coturnix japonica. Besides all these differences, other authors such as [24] and [25] obtained LW of 157.3 g and 162.4 g respectively. In younger quails (4-5 weeks old), [26] recorded higher LWs (242.1 and 284.9 g, respectively) than those obtained at the same age in the present study.…”

“…Other authors have recorded higher MRs. These include [1]; [25] and [52]. These authors obtained between 6% and 9% for the first, 7% and 4.36% respectively for the second and third.…”

“…These authors further obtained CI values ranging from 3.4 to 3.6; 3.52 to 3.69; 4.5 to 5.68 and 3.54 to 4.29 respectively. [25] recorded a feed consumption of 553 g for a production of 162.4 g live weight, i.e. an CI of 3.59.…”
