“…Consequently, the shape index obtained for SF0 and SF5 is higher than that of SF10. These results are closest to those found by Ouaffai et al (2018) who found values of 3,25 and 2,54 cm for length and width, so 78,2 for shape index. Also, feed supplementation with sunflower oil increased the length and width of quail eggs (P<0.0001) in agreement with results found by Lohmann (2018) when laying hens received diets supplemented with soybean oil.…”

The addition of oils in animal nutrition improves growth performances and the quality of products obtained as meat, milk and eggs by providing essential fatty acids. In poultry and especially in layers, vegetables oils are used widely to increase energy in food. In this study, we aimed to evaluate the effects of dietary sunflower oil incorporation on laying performances and egg quality of Japanese quail. A basal diet SF0 was formulated to meet the nutritional requirements for laying quails. Two other foods SF5 and SF10 were obtained by the incorporation of 5 and 10% of sunflower oil in the control food SF0. We used a total of 300 females of quail, aged 42 days old. Quails were housed in cages. They were randomly assigned to the three experimental diets (100 Quails per diet). In total, 30 cages (10 cages/ treatment) were used and each cage contained 10 quails. The results showed that the addition of sunflower oil to the feed of quails during the laying period improved the growth performances of quails by increasing the live weight, reducing the feed conversion index, and therefore ensuring early maturity of females. For egg quality, dietary supplementation with 10% sunflower oil affects positively the weight of eggs, yolk, and albumen without any effect on the rate of these later. On the other hand, the laying rate was not affected by the type of diet. However, the addition of sunflower oil can improve the shape index, haugh unit, and the yolk color score. Dietary sunflower oil supplementation at 10% improves the laying performances of quails without any negative effect on the health status of animals. Supplementing the quails' diet with sunflower oil improves egg quality as haugh unit and yolk color score.

“…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.…”

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

The aim of this study was to contribute to guinea fowl farming productivity. Thus, a socio-economic and technical survey was conducted in Far-North Cameroon and 500 eggs were randomly collected for hatchability assessment. Additionaly, 90 eggs were collected from three localities for physico-chemical analysis. Guinea fowls are raised in free range and 53.3 % of farmers have traditional shelters and no sanitary measures are taken. Farmers have traditional know-how in terms of egg selection techniques for brooding and the management of guinea fowl. They are mostly sold at the market and prices of one living guinea fowl vary between 3 and 5 USD. Major constraints consist in financial needs and lack of appropriate rearing practices. Physico-chemical characteristics showed that weight and edible mater proportions were not affected by locality. Haugh unit of eggs from Bipain (71.04±3.88%) were lower than those from Guidiguis (81.01±7.40%) and Chaochai (84.30±5.83%) and the reverse was observed for lipid and protein contents. Effective hatching rate was 28.96% respectively with an embryonic mortality rate of 42.2% for all eggs. This work shows that guinea fowl farming remains poorly developed and the artificial incubation performances remain low, hence the need for better ways to increase productivity.
