The present study aimed to evaluate the effect of dietary Moringa oleifera (M. oleifera) leaves and/or seed powder on laying Japanese quail performance in terms of egg production, egg quality, blood serum characteristics, and reproduction. In total, 168 Japanese quails (120 hens and 48 males) at eight weeks of age in laying period were randomly distributed to four treatment groups, with six replicates per group and seven birds (five hens and two males) per replicate. The first group (G1) served as a control group, while G2, G3 and G4 groups were supplemented with M. oleifera leaves (ML) and M. oleifera seeds (MS) and their combination ((1 g/kg ML; 1 g/kg MS; and 1 ML g/kg + 1 MS g/kg (MSL), respectively). From the results, feed consumption, feed conversion ratio, egg weight, fertility and hatchability from fertile eggs, egg and yolk index, and Haugh unit were not affected by dietary treatments. However, egg production, egg mass, eggshell thickness, and hatchability were significantly increased and blood aspartate transaminase (AST) and urea decreased in the MS treatment. Both triglycerides and total cholesterol were reduced (p < 0.05) in all treatments with ML, MS, and MSL, with no significant differences in alanine aminotransferase (ALT), albumin, total protein, globulin, and A/G ratio among dietary treatment. Our results clearly indicated that the inclusion of M. oleifera seeds in Japanese quail diet significantly increased egg production and improved hatchability, along with some egg quality parameters, and also lowered some blood biochemical components.

The aim of this study was to investigate the effects of different levels of alfalfa meal on performance, egg quality, egg yolk cholesterol and hatchability parameters of quail breeders. In this trial a total of 90 Japanese quail breeders (30 males, 60 females), 10 weeks old was distributed 5 experimental groups randomly. Each experimental group consisted of 6 replicates of 3 quails (1 males, 2 females) in each. During the 12 weeks experiment period, birds were fed with 5 dietary groups based on corn and soybean meal and containing 0 (control), 10, 20, 40 and 80 g/kg alfalfa meal. Feed and water were offered ad-libitum throughout the experiment. The different dietary levels of alfalfa meal had no significant effect on body weight change, egg production, egg weight, egg mass, feed conversion ratio, egg shell breaking strength, egg yolk triglyceride, fertility, hatchability of fertile eggs or hatchability of eggs set. The feed intake was decreased with 10 or 20 g/kg alfalfa meal levels in the diet. The eggshell weight was best in quails fed 20 g/kg alfalfa meal, and the egg yolk cholesterol was the lowest in quails fed 40 g/kg alfalfa meal. According to the results of this study the addition of 40 g/kg alfalfa meal in laying quail diets decreased the egg yolk cholesterol levels without adverse effect on performance.

This study aims to determine the effect of laser puncture shooting on the reproductive acupuncture points of Japanese quail (Coturnix coturnix japonica) egg quantity (egg production) and internal egg quality (Haugh unit, yolk index, and yolk colour). This research was conducted for 30 days using a sample of Japanese quail aged 4 weeks because for the first 2 weeks, the quail did not produce and it was in production in the last 2 weeks. There were 4 treatments and 25 replications each. So, there were a total of 100 quails. Laser puncture shooting was carried out at 3-day intervals at the Ova point and 6-day intervals at Hu Men, Bei Ji, and Wei Gen points. So, on the first day, laser puncture shooting was carried out at 4 points, on the 4th day, only at 1 point, and then, on the 7th day, it returned to 4 points. And so, it was carried out for 4 weeks. T0 (−) was considered as a negative control because quails are not given laser puncture shooting; T0 (+) was considered as a positive control because quails are treated with laser puncture shooting which is deactivated or a dose of 0 Joule; T1 was a group treated with laser puncture shooting at a dose of 0.2 Joule, and T2 was a group treated with laser puncture shooting at a dose of 0.5 Joule. Then, the research results were analyzed using Analysis of Variance and followed by Duncan’s Multiple Range Test. Laser puncture shooting at the reproductive acupuncture point of Japanese quail (Coturnix coturnix japonica) can increase the quantity of eggs ( p < 0.05 ). While the results of the egg internal quality in the form of the Haugh unit value and the yolk index increased ( p < 0.05 ), the value of the yolk colour did not change compared to the control ( p > 0.05 ). Laser puncture shooting at the reproductive acupuncture point of Japanese quail (Coturnix coturnix japonica) can increase egg quantity (egg production) and internal egg quality (Haugh unit and yolk index) with the best dose of 0.5 Joule.

Five weeks old layer Japanese quail (Coturnix coturnix japonica) birds (180 nos) were randomly distributed into 4 dietary groups with 3 replicates each for 98 days to study the effect of dietary inclusion of acid ensiled fish waste silage on the production performance, egg quality, feed cost, and serum biochemical profile. Fish meal in control diet was replaced by supplementing fish silage at 3%, 6% and 12% of the diet. Significant increase in egg production (p>0.05) and the lowest feed conversion ratio were recorded when birds were fed with 3% silage. But the egg production or feed conversion ratio was not adversely affected by 6% or 12% inclusion of fish silage. Egg quality attributes like weight, shape index, Haugh score, albumen index or yolk index did not differ significantly with the increasing content of silage in the feed. The yolk concentration increased significantly (p>0.05) with increase in fish silage in the diet. The concentration of serum biochemical constituents (total protein, albumen, globulin, cholesterol, triglyceride, alkaline phosphatase, urea and creatinine concentration) did not vary significantly (p>0.05) among the treatments. Serum glucose concentration was the highest in birds fed with 3% fish silage. Lowest cost of feed/kg egg mass was obtained by inclusion of 3% of fish silage in the diet. It was concluded that acid ensilage from freshwater fish waste can replace fishmeal in layer Japanese quail diets without affecting the production of birds besides resulting in reduction of feed cost.

Three hundred ten 12-wek-old laying quails (155 each) were randomly selected from the initial population and kept in individual battery cages. The measurements of growth and egg production were determined to derive RFI. The relationship between RFI and egg quality, blood parameters and carcass characteristics was also determined. The results indicated that the gray quails had significantly higher egg mass and lower broken eggs compared to the white quails. A significant increase for eggshell strength and shell % was found in eggs produced from gray quails compared to white counterparts, although the shell thickness was the same. The results of multiple regression analysis clearly identified a significant effect of metabolic body weight and egg mass in computing expected feed intake rather than body weight gain in both varieties of Japanese quails. Strongly positive correlation between RFI and feed intake in both gray and white quail varieties was found. The same trend was also observed for feed conversion ratio (FCR). Therefore, including RFI in selection criteria of Japanese quail to improve FCR under high environmental temperature is highly recommended.

ABSTRACT: This study was conducted to evaluate the effects of different levels of dietary hot pepper (Capsicum annuum L.) waste supplementation on egg production performance and quality in Japanese quail hens (Coturnix coturnix japonica). A total of 192, seven-week-old Japanese quail layers were divided into 4 treatment groups of similar mean weight (304±0.5 g), each comprising 12 subgroups (including 1 male and 3 females). Treatment birds were fed on experimental basal layer diet supplemented with 1, 2 or 4 g hot pepper waste powder (HPWP) per kg diet. The laying performance was determined by recording feed intake, egg weight, daily egg production, and biweekly egg quality. Results showed that HPWP supplementation to layer diet did not have any significant (P>0.05) effects on body weight and feed conversion ratio, while it had significant effects on feed intake (P<0.01), and laying egg weight, average egg weight, total egg yield (P<0.05). A 2 g HPWP supplementation resulted in the highest total egg yield (P<0.05) with quadratic effects on egg shape index (P<0.05) and albumen pH (P<0.01). According to the values in the study, the egg shape index of 2 g HPWP group was circular and; therefore, attractive to consumers. We highly recommend the non-economic value of 2 g/kg supplementation of hot pepper waste powder, especially for egg production. To conclude, HPWP can be used for quail layer diets due to its beneficial effects on egg quality since it is an economic and easy agricultural by-product obtained from red pepper paste industry waste.
