Abstract The aim of this study was to improve the reproductive ability of native Iraqi chickens with the use of glycitein. The Studie was conducted on a of 120 Iraqi native chickens, consisting of 100 hens and 20 roosters. The chickens were 26 weeks old at the time of the study. The chickens were divided into four treatment groups, with each group consisting of 25 chicks. The experimental design consisted of four groups: the first group served as the non-injection control (referred to as T1), while the remaining groups (T2, T3, and T4) were treated with injections of glycitein at concentrations of 5, 10, and 15 mg/kg body weight, respectively. These injections were given subcutaneously in the neck region, with a frequency of once every 28 days across a span of three periods. Subsequently, an examination was conducted on the percentages of fertility and hatchability, as well as the primary and secondary sex ratios pertaining to female subjects. The results of the study showed that the use of glycitein injection had a beneficial impact on fertility, hatching, as well as primary and secondary sex ratios. Therefore, it can be concluded that the impact of glycitein yields a favourable outcome on both the primary and secondary sexual ratios.

Abstract This study aimed to investigate the impact of implementing Glycetin by injection on the productive features of local Iraqi chickens. 100 female hens and 20 roosters from a local Iraqi chicken population, at age 26 weeks. The sample was divided into three groups, in addition to a control group. Each experimental group had 25 female hens, with the same procedure being performed for each individual hen, and 20 roosters, which were reared separately for the purpose of artificial insemination. The avian specimens were housed in separate enclosures, and the experimental conditions were allocated as follows: the initial condition (Control Group) did not receive any injections, whereas conditions T2, T3, and T4 were administered with varying doses of Glycetin at concentrations of 5, 10, and 15 milligrams per kilogram of body weight, respectively. The results showed improve significant (P<0.05) many aspects such as egg production rate, cumulative egg count, egg mass, egg weight, and feed conversion ratio.

Abstract The aim of this research to examine the impact of different level of Insulin certain biomarkers of local roosters semen after being cooling for varying lengths of periods, roosters semen pooled, diluted with extender, and distributed randomly among five groups: Diluted semen put through the semen cryopreservation technique; the control treatment (C1) 0 insulin; (C2) contained 4 IU/insulin; (C3) contained 5 IU/insulin; (C4) contained 6 IU/insulin; and (C5) contained 7 IU/insulin. After 0, 24, 48 and 72 hours, cooling semen were evaluated for plasma membrane integrity(MI), acrosome integrity(AI), malondialdehyde (MDA) and total antioxidant capacity (TCA). The result showed significant differences between the treatments in terms of MI, AI and TCA in sperm with C5, C3, C2 respectively, but there were no significant differences in terms of MDA. TCA were found to be significantly improved in the fourth storage period.

This study was carried out at the Poultry Research Station / Agricultural Research Department / Ministry of Agriculture, to investigate the effects of implanting genistein (GE) for the period of 1/February/2021 to 16/August/2021. into Iraqi local chickens at various ages on primary (PSF) and secondary (SSF) sex ratios of female, fertility (FE), and hatchability (HA) traits. At the age of 12 weeks, 100 hens and 20 roosters of Iraqi local chickens from the Poultry Research Station were used in this study. After numbering the hens, the birds were housed in individual cages and divided into four treatments (each with 25 chickens) as follows: T1: none implantation; T2, T3, and T4: implantation of 10 mg GE /kg weight at 14, 18, and 22 weeks of age, respectively. The experiment was divided into three periods, each for 28 weeks, and then rated according to the overall average and all of the traits studied. The results showed that implanting GE into hens had a positive influence on FE, PSF, SSF, and estrogen level (ES), especially at 18 weeks of age. There were also significant correlations between traits and ES in hens’ blood. It was also shown that the regression of most traits on ES is first order linear. As a result, it can be concluded that GE has a positive effect on ES, PSF, SSF, with the possibility of predicting sex ratios and sex offspring based on estrogen levels in the blood, and that implantation at 18 weeks of age has produced great results.

This study evaluated the influence of administering different levels of L-arginine into eggs of 0-day-old Japanese quail embryos. On day 0 of incubation, 480 eggs (120 for each treatment group) were injected with 0% arginine (C group), 1% arginine (T1), 2% arginine (T2) or 3% arginine (T3). After hatching, 336 quail chicks (84 chicks produced from each in ovo injection treatment) were placed in an experimental quail house and allocated to four treatment groups of three replicates, with 16 quail chicks for each replicate. Traits involved in this study were hatchability rate, initial body weight (7 days of age), final body weight (42 days old), feed intake, weight gain, feed conversion ratio and blood serum glucose, protein, cholesterol, total lipids, triglycerides, calcium and phosphorus concentrations, and proportional weights of the carcass, breast, legs, backbone, wings, neck, abdominal fat, liver, heart and gizzard. Results revealed that in ovo injection with different levels of L-arginine on day 0 of incubation resulted in significant increases in the hatchability rate, initial body weight, final body weight, feed conversion ratio, and blood serum glucose, protein, total protein, calcium and phosphorus concentrations, as well as the proportional weights of the carcass, breast, legs, liver, heart and gizzard. However, there was no significant difference in feed intake between treatment groups. Significant decreases were recorded in blood serum cholesterol, total lipids and triglyceride concentrations, and proportional weights of the backbone, wings and abdominal fat. In conclusion, the inoculation of different levels of L-arginine into eggs of 0-day-old quail embryos, especially at the levels of 2% and 3% arginine, resulted in a significant improvement in the productive and physiological performance of the quail. Hence in ovo injection with L-arginine could be used as a tool for enhancing the hatchability rate and productive performance of quail hatched from the egg.

This experiment was performed to investigate the influence of different oils in the diets of laying quail on their egg quality characteristics. One hundred and twenty 7-wk old Japanese quails (Coturnix coturnix japonica) were allocated to four groups with three replicates containing 10 quail each (30 quail per each treatment group). They were fed for 13 weeks (including one week of adaptation period) on diet s containing 3% oil from different sources, viz. either sunflower (T1), linseed (T2), maize (T3), or fish oil (T4). Inclusion the diet of laying quail with fish oil (T4) and maize oil (T2) resulted in significant increase with respect to egg weight, yolk weight, albumen weight, yolk diameter, yolk height, albumen diameter, albumen height, shell thickness and Haugh unit during all periods of experiment and in total means of thes e parameters. However, the addition of different oil sources used in this experiment to quail diets did not significantly affect total means of shell weight, relative weight of albumen and relative weight of shell, while total means of relative weight of yolk, yolk index and albumen index were higher in the birds receiving diets containing fish (T4) and maize (T2) oil than in other treatments (T1 and T3). The results of this experiment clearly demonstrated that supplementation the laying quail diet with fish and maize oil improved most criteria of egg quality. Therefore, incorporation of fish and maize oil into the diets of Japanese quail may have practical value in manipulating egg quality.

The objective of this experiment was to determine the effects of dietary supplementation with different fat sources on blood parameters of Japanese quail (Coturnix coturnix japonica). Eighty four 7-week old laying quail were randomly assigned to 4 treatment groups (21 birds per group) with 3 replicates for each treatment group and fed for three months on a commercial diet supplemented with 3% of either sunflower oil (T1), flax oil (T2), corn oil (T3) or fish oil (T4). The birds received water and feed ad libitum during the experiment. During the last month of experiment blood samples were collected fortnightly from each bird. The first blood samples collection was used to determine fresh blood parameters, while the second blood samples collection was used after pooled blood samples for each replicate of treatment group to determine serum chemistry traits. Dietary supplementation with 3% fish oil (T4) caused a significant (p<0.05) increase in erythrocyte number, Packed Cell Volume (PCV), hemoglobin concentration, Mean Corpuscular Values (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), thrombocyte number and leukocyte number and serum total protein, albumen, globulin, glucose, High Density Lipoprotein (HDL), Alkaline Phosphatase (ALP), calcium and phosphorus concentration, followed by the results of flax oil (T2), whereas sunflower oil (T1) and corn oil (T3) revealed the lowest values respecting these traits. However, adding sunflower (T1) and corn oil (T3) to the diet of laying quail resulted in significant (p<0.05) increase in percentage of reticulocytes and Heterophil to Lymphocyte (H/L) ratio and serum total cholesterol, triglycerides, Low Density Lipoprotein (LDL), uric acid, creatinine, Aspartate Aminotransferase (AST) and alanine aminotransferase (ALT), followed by the results of the flax oil (T2), while fish oil (T4) exhibited the lowest means with relation to these traits. From this experiment it is concluded that dietary fish and flax oils at inclusion level of 3% resulted in significant improvement in blood profile of laying quail. Consequently, fish and flax oils can be added during the laying period to the diet of Japanese quail to enhance general physiological status of these birds.

The present work aimed to compare the effect of different dietary oil sources on semen characteristics of quail males. Japanese quail males (21 per diet) were fed one of four treatment diets: diet containing sunflower oil (T1), flax oil (T2), corn oil (T3), or fish oil (T4) as the oil source. Birds were 6 weeks old at the beginning of experiment. Following two weeks of adaptation period, semen was collected twice a week fortnightly from each male to evaluate semen traits included in this study. First semen collection was used to evaluate ejaculate volume, sperm concentration, live in total sperm, live normal sperm, sperm quality factor and abnormal sperm, while the second semen collection was used after pooled the semen of each replicate (7 male each) for determine semen glucose, protein, Aspartate Aminotrnsferase (AST), Alanine Aminotransferase (ALT) and Alkaline Phosphatase (ALP). Results of this study revealed that fish oil group (T4) surpasses other treatment groups as regards all semen characteristics involved in this study followed by the results of flax oil (T2), whereas the worst results for these traits were recorded when the diets of quail males supplemented with sunflower oil (T1) and corn oil (T3). In conclusion, fish oil and flax oil supplemented diets can be used as efficient tool for improving reproductive performance of Japanese quail males.

To assess the effects of dietary oil source on productive and reproductive traits, sunflower oil, flax oil, corn oil or fish oil were induced in quail diets. One hundred and sixty eight 7 weeks old Japanese quail were randomly assigned to 4 groups (12 males and 30 female each) with 3 replicates per group containing 4 males and 10 f emales each and fed for 13 weeks (including one week as adaptation period) on a commercial diet supplemented with 3% of sunflower oil (T1), Flax oil (T2), corn oil (T3), or fish oil (T4). The birds received water and feed ad libitum during the study. Results of experiment revealed that dietary supplementation with different sources of oil had no significant effect on male body weight, female body weight and feed consumption of quails. Dietary fish oil at the inclusion level of 3% (T4) recorded the best results (p<0.05) in regard to egg weight, hen-day egg production, egg mass, cumulative egg production, feed conversion ratio, fertility, hatchability of eggs set, hatchability of fertile eggs and embryonic livability, followed by the results of flax oil (T2), whereas the lowest values for these traits recorded for corn oil (T3) followed by the results of sunflower oil (T1) which recorded the lowest means with relation to characteristics included in this study. However, there was no significant difference between T2 and T3 in respect to feed conversion ratio during the entire period of experiment. In general it can be recommended that use of fish oil (T4) and flax oil (T2) at levels of 3% in Japanese quail diet during the laying period get higher economic efficiency without adverse effects on productive and reproductive performance. Therefore, providing fish oil or flax oil to quail throughout their laying period may be a simple means to enhance reproductive efficiency of these birds.

2 Abstract: This experiment was performed to investigate the effect of dietary supplementation with linseed on egg quality of laying quail. A total of 320 Japanese quail (Coturnix coturnix japonica) 9-wk old were allocated to 4 treatment groups with 4 replicates containing 20 quail each. Birds were fed commercial diet containing 0% (C), 2% (T1), 4% (T2) or 6% (T3) linseed. Birds received water and diet ad libitum during the total period of experiment. Egg quality characteristics were monitored over 3 consecutive 21-d periods. Egg quality criteria involved in this experiment were egg weight, yolk diameter, yolk height, yolk weight, albumen height, albumen weight, shell weight, shell thickness, Haugh unit, albumen percentage, yolk percentage and shell percentage. Results revealed that supplementing diet of laying quail with linseed resulted in significant increase in total means of egg weight, yolk diameter, albumen height, shell thickness, Haugh unit, albumen percentage and albumen weight. Total means of shell weight and yolk percentage were not significantly (p>0.05) different from quails consuming 0, 2, 4 or 6% linseed; However, total mean of shell percentage was reduced (p<0.05) in laying quails fed linseed when compared to control group. In conclusion, Feeding laying quails with different levels of linseed (2%, 4%, or 6%) caused significant improvement as regards most of egg quality parameters included in this experiment. Therefore, adding linseed to the ration could be used as a good tool for improving productive performance of Japanese quail.
