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

In Côte d’Ivoire, the quail breeding is confronted with lack of food specific to species. Thus, in south-east this country, an experimental study was conducted at ISMOREL farm sub-prefecture Adiaké. This study, which aims improve productivity day-to-day farms, focused on grain size feed. From grower (GD) and layer (LD) diets, 5 diets have been manufactured. There are: LD a particle mm, 3 GD mm as well 2 mm. The growth parameters related 750 two-week-old unsexed subjects weighing 49.67 ± 0.17 g average. For egg-laying, 300 female quails were used 6-week-old. results showed influence (LD 2) such feed intake (186.96 4.73 153.46 5.33 g), average live weight (142.37 1.76 155.85 1.85 daily gain (4.29 1.22 g/d 4.74 1.25 g/d), age first egg laid (49.33 0.58 d 46.33 1.26 d) egg-laying rate (67.24 30.97% 74.12 34.03%). At end it appears that induces better performance Japanese quail.
