The aim of this study was to evaluate the effect of levels of choline and digestible methionine + cystine in diets for quail in the laying phase. A total of 280 Japanese laying quail were assigned to one of eight treatments in a completely randomized design in a 4 × 2 factorial arrangement consisting of dietary supplementation with four levels of choline (0.0, 0.042, 0.084 and 0.126%) and two levels of digestible methionine + cystine (0.857 and 0.685%), with five replicates and seven birds per plot. The experimental period was 84 days, represented by four 21-day evaluation cycles in which quail performance and egg quality were evaluated. There was no interaction effect between the factors for any of the studied variables, except quail weight. The highest tested levels of methionine + cystine and choline supplementation improved egg weight, feed conversion egg mass?1 and yolk percentage. By contrast, albumen percentage decreased linearly as choline inclusion in the diet was elevated. The choline supplementation levels induced a quadratic response from eggshell percentage, whose optimum result was estimated at the choline level of 0.05% in the diet. Egg specific gravity decreased linearly as choline supplementation was increased. The indicated level of digestible methionine + cystine in the diet of Japanese quail in the laying phase is 0.857%, while choline should be supplemented at 0.126%.

“…The feed consumption of laying quail (age of 7-11 weeks) in treatment D (15% CPF) in the diet is 21.58 g/head/day. This feed consumption was similar to that observed by Nuraini et al (2017b), who showed that the feed consumption of quails (age 7-11 weeks) in a range of 21.20-22.03 g/bird/day and higher than the results of a study by Khairani et al (2016), who found that the feed consumption of quail was 17.64-20.52 g/bird/day when fed 18% crude protein.…”

“…In terms of feed conversion, feed conversion that was not significantly different between treatment A with treatment B, C and D was due to the same feed consumption and egg mass in treatments A with, B, C and D. According Khairani et al (2016), the feed conversion ratio is the ratio between feed intakes in producing a number of eggs. Feed conversion can indicate the production coefficient; a smaller value indicates more efficient use of feed to produce eggs.…”

“…Feed conversion can indicate the production coefficient; a smaller value indicates more efficient use of feed to produce eggs. According to Khairani et al (2016), who observed that feed conversion is influenced by feed consumption and egg mass such that if there is an increase between them, the feed conversion values will remain balanced. The feed conversion of laying quail rations at the age of 7-11 weeks in treatment D (15% CPF) was determined to be in the ratio is 3.67.…”

Improving the quality of cocoa pods through fermentation with Pleurotus ostreatus reduced its crude fiber content, especially for lignin and cellulose. Fermentation of cocoa pods product increased their utilization in poultry diet. An experiment was conducted to determine the effect of feeding cocoa pods waste fermented by Pleurotus ostreatus on the laying performance and egg quality of quail. This experiment employed completely randomized design with five dietary treatments: 0%, 5%, 10%, 15% and 20% cocoa pods fermented by Pleurotus ostreatus in the diets and four replications. 200 laying quail (7 weeks of age) were randomly allocated into 5 treatments (10 birds per treatment) and 4 replications. Diets included iso nitrogen 20% and iso metabolism energy 2800 kcal/kg. The results of the experiment indicated that feed intake, hen-day egg production, egg weight, egg mass production, and feed conversion were not affected but egg cholesterol was affected by increasing cocoa pods fermented products in the diet. In this experiment, a diet which utilized 15% cocoa pods fermented using Pleurotus ostreatus maintained the laying performance of quail and reduced egg yolk cholesterol (20.30%).

“…The average egg yolk scores in this study showed that the utilization of cricket meal significantly increased the score of yolk color variable. Yolk color was influenced by xanthophylls (one of two major divisions of the carotenoid group) in diet (Khairani et al, 2016). Xanthophylls give the color characteristic to the egg yolks.…”

Feed cost contributes 80% of the total cost of production in quails. The utilization of cricket meal as a protein source can be a solution to reduce feed costs. The cricket has a high nutritive value, especially protein content, and is one of potential insects to be used as a source of alternative protein to replace fish meal in animal diet. This study aimed to evaluate the effect of cricket meal on the production and physical quality of japanese quail egg (Coturnix coturnix japonica). The experiment used 200 five-week-old female quails with an average body weight of 125.4 g. The completely randomized design (CRD) was employed for the experiments with 5 treatments and 4 replications (10 birds per replication). The dietary treatments were T0: diet without cricket meal, T1: diet containing 2% cricket meal to replace 25% of fish meal, T2: diet containing 4% cricket meal to replace 50% of fish meal, T3: diet containing 6% cricket meal to replace 75% of fish meal, and T4: diet containing 8% cricket meal to replace 100% of fish meal. Results revealed that utilization of cricket meal in the quail ration significantly increased egg production (P<0.05) and positively affected physical quality of quail eggs, such as egg weight, egg white weight, eggshell weight, and yolk score. It can be concluded that cricket meal can partially or fully replace fish meal in the diet of layer quails.
