-The objective of this study was to compare fattening performance, carcass traits, and egg quality of Japanese quails with different feather colors (white, dark brown, golden, and wild-type). In the study, 360 one-day-old quail chicks with 4 different feather colors were used as animal material. Quails were fed ad libitum for 42 days to determine fattening performance and carcass traits. To determine egg traits, 48 hens from each group, in a total of 192, were selected and caged according to feather color. Eggs were collected for four consecutive weeks and egg quality characteristics were measured. Different feather colors had a significant effect on live weight, feed intake, feed conversion ratio, and carcass characteristics. Significant differences between the groups were detected for egg weight, specific gravity, shape index, shell weight, albumen weight, yolk weight, albumen index, and yolk index. Japanese quails with all four feather colors can be reared depending on the choice. However, due to lower feed conversion ratio, white-feathered quails may be preferred for meat production purposes. Color variations should be considered when selecting quails.
-The present study was conducted to determine the effects of supplemented juniper berry (Juniperus communis) on fattening performance and some carcass traits of quails. A total of 150 one-day-old Japanese quail chicks were randomly divided into five groups (one control and four treated groups) with three replicates. Four different juniper berry levels (0.5, 1, 1.5, and 2%) and a control treatment (0%) were added to the diet. Juniper berry supplementation to the diets initiated at the end of the 1st week and sustained for seven weeks. Live weight, feed intake, and feed conversion ratio during the trial and some carcass traits after slaughter were determined. Juniper berry supplementation in the diet during seven weeks of growing period significantly increased body weight, cumulative feed intake, and feed conversion ratio of the treated groups. Carcass weight, carcass yield, and breast yield were also significantly increased by supplemented juniper berry. No significant difference was observed between viability of different groups. Supplementation of 0.5-1% juniper berry in quail diets has positive impacts on fattening performance and carcass traits.
Objective. This study was conducted to research the effects of different levels of dried white mulberry (Morus alba) pulp supplementation in diets of laying quail on yield performances, egg quality, blood parameters, yolk fatty acid profiles and cholesterol concentrations. Materials and Methods. A completely randomized experimental design, with four treatments and four replicates, was applied. The experimental treatments were M0: control diet; M4: dietary inclusion of 4% mulberry pulp; M8: dietary inclusion of 8% mulberry pulp; M12: dietary inclusion of 12% mulberry pulp. This experiment was carried out for 4 weeks, and 128 7-week-old female quail were used. Results. Addition of dried mulberry pulp to the diet significantly affected weekly feed intake, egg yield, albumin index, yolk weight, triglyceride, LDL, serum cholesterol and yolk cholesterol levels (p<0.05, p<0.01). The feed conversion ratio, egg weight, and egg yolk fatty acid profile were not significantly affected by the dried mulberry pulp in the diet. Conclusions. As a result, it may be stated that adding dried mulberry pulp up to 8% of the diets of laying quail does not cause any adverse effects and may be used without any problems.
-This study was conducted to compare live weight, feed intake, feed conversion, mortality rate, and some carcass characteristics of Japanese quails reared under organic and conventional conditions. A total of 180 one-day-old quail chicks were randomly divided into six groups -Conventional, consuming conventional feed ad libitum; Control (C), consuming organic feed ad libitum; C+P, consuming organic feed ad libitum + pasture; 80C+P, consuming 80% of control + pasture; 70C+P, consuming 70% of control + pasture; and 50C+P, consuming 50% of control + pasture -with three replicates. The conventional group was kept for 6 weeks, while the control, C+P, 80C+P, 70C+P, and 50C+P groups were reared until the end of 10 weeks of age. Raising systems significantly affected live weight, feed intake, and feed conversion. The analysis showed that the meat yield of quail raised in organic conditions had better results than those raised in conventional conditions in terms of appearance, color, aroma, and flavor. The group consuming 50% of control plus pasture was more advantageous than the other organic groups and the conventional group at the end of the 10-week fattening period. The organic production system can be a good system to meet the demand of consumers who seek more natural products.
