  The present experiment, was carried out to evaluate the effects of dietary Popy Seed Oil (PSO) and Sunflower Oil (SFO) alone or in combination in quail diets on the performance, reproduction and egg quality parameters and fatty acid composition of egg yolk. Totally 196 female and 56 male Japanese quails of 7 weeks of age were individually weighed. The initial body weight was comparable. The birds were randomly assigned to 1 of 7 dietary treatments, with each treatment replicated 4 times randomly among the batteries with 7 female and 2 male quails for replicate. Control group was fed a diet unsupplemented PSO and/or SFO. The diets of treatment groups were supplemented PSO and SFO as follows: Group I; 15 g kg-1 PSO, Group II; 15 g kg-1 SFO, Group III; 7.5 g kg-1 PSO + 7.5 g kg-1 SFO, Group IV; 30 g kg-1 PSO, Group V; 30 g kg-1 SFO and Group VI; 15 g kg-1 PSO + 15 g kg-1 SFO, respectively. The birds received water and feed ad libutum during the study. The addition of PSO and SFO alone or in combination did not significantly affect performance, hatchability and fertility, egg quality traits (egg shell thickness, egg albumen index, egg yolk index and egg haugh unit). However, dietary PSO, SFO and PSO + SFO supplementation significantly (p<0.05) caused to decrease on saturated fatty acid levels in egg yolk. On the other hand PSO, SFO and PSO + SFO supplementation to the experimental diets resulted in increase (p<0.001) on unsaturated fatty acid in egg yolk. The results of this study, demonstrated that PSO, SFO and PSO + SFO supplementations into quail diets caused significant positive effects due to decreasing of saturated fatty acids and increasing of unsaturated fatty acids in egg yolk without adverse effects on laying performance, hatchability, fertility and egg quality traits of laying quails.

  The aim of this research is to determine the effects of dietary peppermint leaves on egg production, feed consumption, feed conversion ratio, egg quality parameters and hatching parameters in quails. Totally 180 laying quails of 15 weeks age were used. Animals were divided into 6 groups (30 animals in each group). Five of them were supplemented by different levels of peppermint up to 50 g kg-1. The control group received no peppermint. The differences on feed conversion ratio, egg production, egg quality parameters were not significantly different between the groups. The 20 g kg-1 peppermint supplementation group consumed less daily feed. Among the hatching parameters, the values regarding late embryonic mortality and pipped were lowest in control group. It was concluded that peppermint supplementation into the ration up to 50 g kg-1 caused no important adverse effect except yolk index value in quails and 20 g kg-1 peppermint supplementation was produced better results than the other groups regarding feed consumption values.

  There are numerous molting programs used in research and in the commercial layer industry. If the program is conducted properly, the productive life of a laying hen flock can be substantially increased. Many research studies on molting programs have focused on the physical manipulation of the program itself as well as the nutritional recovery of the diet used. Though, there are many methods employed to induce molting of commercial hens, feed removal is used most frequently. Withdrawal of feed for up to 10-14 days is commonly used, resulting in a temporary state of fasting. Logman and Brown Nick strains were used in this study with a production capacity of 78.7 and 68.2% at 72nd week of rearing period. Molting was induced by Feed Withdrawal (FW). Briefly, feed was replaced with mosaic for 10 days, followed by supplementing barley gradually containing 1-1.5% mosaic for the next 10 days. The FW treatment resulted in total cessation of egg production within 14 days for Logman and 28 days for Brown Nick while the birds remained out of production. The rate of egg production was significantly improved by force molting treatments when compared with their 2 weeks period (72-73 week) of the commencement of treatments. Egg production period for Logman hens was shorter than that of Brown Nick which resulted in lower yield in total. Return to pre-molt status was similar in both groups; however menarche time varied between strains. Post-molt menarche and return to pre-molt status had occurred on day 21 for Logman and day 5 for Brown Nick. Post-molt hen-day production peaks were at 86th week for Logman with an 88.8% yield and 83rd week for Brown Nick with 75.0% yield. Brown Nick produced more cracked eggs between 75th and 83rd weeks of the experiment while Logman produced more cracked eggs than that of Brown Nick did during the other periods. Mortality, was evidently high in both groups during the molting period. However, throughout the study, mortality for both molting groups was within the expected range As a result of this study, Brown Nick performed better than Logman in terms of egg production, post molt-menarche time, cracked eggs while Logman was better in terms of post molt hen-day peak and mortality figures.
