Heat detoxification of Jatropha cucas meal and its effect on productive and reproductive performance of quail

Jatropha is a large, multipurpose, drought-tolerant plant with many traits and great potential as a biofuel crop. It originates from Central America but is now distributed throughout the tropics, including Africa and Asia. The study determines whether the dietary inclusion of raw Jatropha cucas meal (RJM, 3.5%) had negative impacts on the reproductive and productive performances of male Japanese quail as well as whether these impacts could be mitigated by heating the jatropha meal at 100°C for 24 or 48 h (JH24 or JH48 respectively). One hundred twenty healthy mature male quails at the age of 12 wk were assigned randomly to 4 treatments. Every treatment had 6 replicates, with 5 birds per replicate. The RJM caused a considerable decline in fertility and a high mortality rate in quail, whereas heat-treated jatropha meal (JH24 or JH48) decreased these unwanted effects. The RJM significantly increased triglycerides, aspartate aminotransferase (AST), and alanine aminotransferase (ALT), while reducing total protein and albumin. These values returned to normal in the JH24 and JH48 groups. The RJM significantly reduced the testosterone and increased estradiol and hepatic content of vitellogenin (Vtg) and estrogen receptor alpha (ERα) while they were normal in JH48 group. Superoxide dismutase (SOD) and catalase (CAT) activities, and the reduced glutathione (GSH) content in testicular tissues were significantly reduced in the RJM group when compared to control. Protein carbonyl (PC), malondialdehyde (MDA), and 8-hydroxy 2 deoxyguanosine (8-OHdG) levels were significantly increased in the RJM group when compared to control. Heating of JM for 48 h reduced the 8-OHdG and MDA levels toward the control level better than JH24 and restored PC to normal. Based on the obtained results, The toxic components in JM could be eliminated through heat treatment, and extending the treatment duration to 48 h is recommended for transforming the potentially harmful jatropha meal into an alternative protein source for livestock nutrition.

Effects of dietary supplement with licorice and rutin mixture on production performance, egg quality, antioxidant capacity, and gut microbiota in quails (Turnix tanki)

This study was conducted to evaluate the effect of licorice and rutin on production performance, egg quality, and mucosa antioxidant levels in Chinese yellow quail. A total of 240 Chinese Yellow Quail (400-day-old) were randomly distributed into 5 groups: the Control group, fed with a basic diet; the LR1 group, fed with basal diet supplemented with 300+100 mg licorice and rutin mixture/kg diet; the LR2 group, fed with basal diet supplemented with 300+200 mg licorice and rutin mixture/kg diet; the LR3 group, fed with basal diet supplemented with 600+100 mg licorice and rutin mixture/kg diet and the LR4 group, fed with basal diet supplemented with 600+200 mg licorice and rutin mixture/kg diet. Compared with the control, supplementation with the licorice and rutin mixture improved the laying rate and eggshell thickness whereas decreased the feed conversion ratio of quails. Moreover, dietary supplementation with the licorice and rutin mixture improved the antioxidant capacity by increasing the activity of the superoxide dismutase (SOD) level and decreasing the concentration of malondialdehyde (MDA) in the jejunal mucosa. The licorice and rutin mixture altered the composition of intestinal microbiota by influencing the relative abundances of Bacteroidetes and Bacteroides. The relative abundances of the Bacteroidetes were significantly related to the laying rate of quails. In addition, the mixture of licorice and rutin was also effective in reducing the relative abundance of intestinal Proteobacteria and Enterobacter in quails, reducing the accumulation of antibiotic-resistance genes. The results revealed that supplementation of licorice and rutin mixture to the diet improved production performance, egg quality, and antioxidant capacity and modified the composition of intestinal microbiota in quails. This study provides a reference for Chinese herbal additives to promote production performance by modulating quail gut microbes.

Marine macroalgae as an alternative in the feeding of broiler quails in an environment of thermal stress

The objective of this research was to evaluate the productive performance, carcass quality, and intestinal biometry of European quails (Coturnix coturnix coturnix), kept under cyclic heat stress (air temperature of 32.5°C±0.5) receiving a ration with different concentrations (0, 2.5, 5, and 7.5%) of seaweed meal of Sargassum sp. A total of 240 quails were used, distributed in a completely randomized design with 4 levels of bran inclusion, 6 replications, and 10 birds per experimental unit. An analysis of variance (ANOVA) was performed, and the means were compared by Tukey's test with 5% probability and subjected to regression by PROC REG of SAS® (2002). No similarity was observed in water and feed consumption between treatments. There was a significant difference in most of the variables studied, with a significant difference only occurring in the dorsum, gizzard, and large intestine. Therefore, it is recommended to include up to 7.5% of sargassum bran in the diet of European quails kept under a 12-h heat cycle (32°C±0.5).

Coated organic acids with essential oils in Japanese quail’s fed restricted during the 2nd week of age: effects on performance, carcase traits, blood profile, antioxidants status, and caeca microbiota

This study aimed to evaluate the effect of Coated Organic Acids with Essential Oils (COAWEO) supplementation on performance, carcase traits, blood biochemistry, antioxidant status, and gut microbiota of Japanese quail (JQ) fed restricted during the 2nd week of age. Five hundred and forty, 7-days old JQ were distributed into 6 groups with six replicates/groups. The feed restriction (FR) was applied only at days 7, 9, 11, and 13 of age. Two levels of FR were used: −12.5 and −25.0% of the amount of feed consumed by the control group (feeding ad libitum), on the previous day. The diets (control, FR12.5 and FR25.0) were fed with or without 100 g/ton of COAWEO. The results indicate that FR and COAWEO-supplemented diets did not affect weight gain, feed intake, and carcase weight. The feed conversion ratio (FCR) was improved by FR during 7–42 days of age. The total bacterial and Lactobacilli counts in the caeca were, respectively, decreased and increased due to FR and COAWEO. Japanese quail can tolerate 12.5% FR without adverse effects on growth performance, carcase traits, blood biochemistry, and gut microbiota. FR25.0 group supplemented with COAWEO showed improved growth performance than the control without any adverse effect on carcase traits, blood biochemistry, and gut microbiota.

Laying performance and egg characteristics of Japanese quail fed rations containing different levels of Maxigrain as a feed additive

The performance, egg characteristics and lipid profile of Japanese quail (Coturnix japonica) fed diets containing different levels of Maxigrain as a feed additive were investigated. A total of 225 (7 weeks) old Japanese quails weighing 235-248 g at the point of lay were allotted to 5 dietary treatments in a completely randomized experimental design with 5 replicates of 9 birds each. Dietary treatments for the entire 56 of days the feeding trial included: T1: 0 g of Maxigrain kg-1 diet, T2: 0.5 g Maxigrain kg-1 diet, T3: 1 g Maxigrain kg-1 diet, T4: 1.5 g Maxigrain kg-1 diet and T5: 2 g Maxigrain kg-1 diet. The results of the study showed that values for average daily feed intake, egg length, egg diameter, egg shape index, cholesterol, high density lipoprotein, low density lipoprotein, triglyceride, albumen weight, albumen height and yolk height were not affected by the treatment (P > 0.05), while dietary treatment significantly (P < 0.05) affected the values for the average daily weight gain, egg weight, egg mass, egg yolk weight and shell thickness among the treatments with T4 and T5 having the highest values of the above variables. It was concluded that T4 and T5 treatment could be safely included in the diet for improved performance in laying quail.

Eggs Quality of Japanese Quails Gave Fermented Dragon Fruit Peel (Hylocereus Sp.) Extract in Drinking Water

This 10-week study aims to examine the performance and egg quality of Japanese quail given a fermented dragon fruit peel (Hylocereus sp) extract in their drinking water. The research methodology employed was a completely randomized design (CRD) consisting of 5 treatments, each treatment with 4 replications and each replication comprised of 10 quails, total of 200 quails of 6-weeks-old. R0 = drinking water without dragon fruit peel extract; R1 = drinking water containing 2% dragon fruit peel extract; R2 = drinking water containing 3% fermented dragon fruit peel extract; and R3 = drinking water containing 4% dragon fruit peel extract. The factors measured were eggs quality of Japanese quail. The findings of the investigation showed that treatment R1, R2 and R3 enhanced eggs quality (eggs weight % HDP, and eggs yolk colour) significantly (P<0,05) than R0. It may be stated that treatment of 2%,3% and 4% of fermented dragon fruit peel extract in drinking water increased eggs quality ( eggs weight, %HDP, eggs yolk colour) of the quail 6-16 week.

Effects of black pepper and turmeric powder on growth performance, gut health, meat quality, and fatty acid profile of Japanese quail.

In poultry production, the search for alternatives to in-feed antibiotics continues unabated. This study investigated the effects of dietary supplementation of black pepper and turmeric powder, separately or in combination, on the growth performance, gastrointestinal microbiota population, intestinal morphology, serum biochemical parameters, meat quality, and meat fatty acid profile in Japanese quails. Five hundred-day-old mixed-sex Japanese quail chicks were randomly assigned to one of five treatments: a control diet (CON); CON +0.2% antibiotic flavomycin as an antibiotic growth promoter (AGP); CON +0.5% turmeric powder (TUP); CON +0.5% black pepper powder (BPP); and CON +0.5% TUP, and 0.5% BPP (MIX). The findings showed that quail chicks fed AGP and TUP throughout the rearing period had better body weight gain (p = 0.007) and feed conversion ratio (p = 0.02) than the other treatments. The TUP, BPP, and MIX feeds reduced (p = 0.005) abdominal fat percentage. The MIX group had a better breast muscle water-holding capacity (p = 0.04) and lightness index (p = 0.02) and lower (p = 0.02) malondialdehyde concentration after 7days of refrigerated storage. Feeding BPP, TUP, and MIX diets decreased (p = 0.001) serum cholesterol concentration. Quail chicks fed the CON diet showed significantly higher coliform counts in the crop and ileum (p < 0.001), whereas the lactic acid bacterial population was lower (p = 0.008) in the ileum. Birds that received the MIX diet exhibited a higher (p = 0.02) villus height to crypt depth ratio in the duodenum compared to the other groups. The tested feed additives increased (p < 0.001) villus height in the jejunum and ileum compared to other groups. Feeding the TUP, BPP, and MIX diets reduced (p < 0.001) total saturated fatty acid content and increased (p = 0.004) total polyunsaturated fatty acid concentration, where the MIX diet had the best results. Overall, the present data indicate that supplementing the basal diet with turmeric powder enhances the growth performance of Japanese quails. In some respects, such as gut health and meat quality, combining turmeric powder and black pepper powder was more effective than using them independently.

Influence of thyme and turmeric essential oils supplementation on growth performance, nutrient utilization and economics of Japanese quails

This experiment aimed to study the effect of dietary thyme and turmeric essential oils supplementation on growth performance, nutrient utilization and economics of Japanese quails. For this purpose, a total of 180 six-day-old Japanese quail chicks were randomly assigned into five different treatment groups, each with three replicates (12 birds per replicate). The experiment was conducted for 35 days. Different treatment groups of Japanese quails were designated as T0 (Basal diet without essential oils), T1 (Basal diet with 0.2% thyme essential oil), T2 (Basal diet with 0.3% turmeric essential oil, T3 (Basal diet with 0.125% thyme + 0.075% turmeric essential oils), and T4 (Basal diet with 0.075% thyme + 0.125 % turmeric essential oils). At the end of experiment, it was found that dietary supplementation of thyme and turmeric essential oils reduced feed consumption, improved body weight gain, feed conversion ratio and protein efficiency ratio, with Japanese quails of T4 group showing best performance during overall experimental period. The feed cost per kg weight gain was minimum in treatment T4 over other treatment groups. Addition of thyme and turmeric essential oils in diet significantly enhanced nutrient utilization in Japanese quails. In conclusion, supplementing thyme and turmeric essential oils in combination at 0.075% and 0.125% of feed improved growth performance, utilization of nutrients and reduced feed cost per kg weight gain in Japanese quails.

Effects of Reishi Mushroom (Ganoderma Lucidum) Powder Inclusion into Quail Diets on Animal Performance, Carcass Traits, Intestinal Microflora and Serum Parameters

This study was carried out to determine the effects of reishi mushroom (Ganoderma lucidum) powder inclusion into quail diets on live weight, live weight change, feed consumption, feed conversion ratio, carcass traits, intestinal microflora and serum biochemical parameters of the animals. Dietary reishi mushroom (RM) addition did not influence live weight changes of the treatment groups (P&gt; 0.05). Weekly and overall feed consumptions of the treatment groups were not influenced by RM supplementations (P&gt; 0.05). There were not any significant differences in feed conversion ratios of the treatment groups (P&gt;0.05). Dietary RM inclusion did not affect the overall carcass parameters (P&gt; 0.05). The differences in intestinal bacteria populations of the treatment groups were not found to be significant (P&gt; 0.05). Also, there were not any significant differences in blood serum total cholesterol, glucose, total protein and triglyceride levels of the treatment groups (P&gt; 0.05). It was concluded that dietary RM inclusion into animal diets had a little effect on performance and carcass traits of Japanese quail. But there were slight improvements in some parameters due to antioxidant and antimicrobial effects of reishi mushroom. Further research is recommended to be conducted with greater ratios of dietary RM and with different poultry species.

This study was conducted in the farm of the Department of Animal Production of the College of Agriculture - Tikrit University for the period from 8/11/2021 to 2/2/2022, and the aim of the study was the effect of egg weight and breeding system on the productive performance of Japanese quail during the growth and egg production stages. 490 un naturalized one-day-old birds were raised from egg hatching collected and graded into three weight categories, low (8-10) gm, medium (10.1-11) gm and high (11.51-12.5) gm and divided into Three groups based on the weight of hatched eggs from (high, medium, low) to a ground breeding system and cages. The study included two stages, the first is the growth stage from (1-36) days old, and the second is the production stage from(37-78) days old. The results of the statistical analysis showed the following: (1) Effect of the breeding system: (A) There is a significant difference (P≤0.05) for quails raised in the ground breeding system in the following characteristics: weight at sexual maturity, while there were no significant differences in age at sexual maturity in the growth stage. (B) There is a significant (P≤0.05) superiority (P≤0.05) of quail birds raised by the ground breeding system in the following characteristics: average egg weight. While there were no significant differences in the weight of eggs for the first, second and third periods, the number of eggs. (2) Effect of egg weight, (A) There is a significant superiority (P≤0.05) of hatching quail birds from high-weight eggs in the characteristics of weight at sexual maturity, and age at sexual maturity for the stage of growth. Whereas, significant superiority (P≤0.05) was found in the following traits during the production stage: (A) High weight eggs: weight of the first egg, weight of eggs. (B) Low weight eggs: there were no significant differences between the treatments in terms of number of eggs,

Production Performance and Sperm Characteristics of Quail (Coturnix-coturnix japonica) with Different Concentrations of Yolk Immunoglobulin

Quails are classified according to their immunity to different IgY concentrations. Quail IgY concentrations range from 0 to 1200 µg ml-1, and these IgY concentrations may affect production and reproductive performance. This study aimed to analyze IgY concentrations in male quail and to compare production and reproductive performance at different IgY concentrations. Forty-two male quail at five weeks of age participated in the study, including 29 quail with low IgY concentration (210-393 µg ml-1)  and, 13 with intermediate IgY concentration (403-564 µg ml-1). The observed productive performances were feed intake, initial body weight, final body weight, weight gain, feed conversion, morbidity, and mortality. In addition, this study observed testicular weight and macroscopic and microscopic semen quality for reproductive traits. Differences in production and reproductive performance of each group were analyzed using an independent-sample t-test. The result showed that male quail with different IgY concentrations were equal in all productive traits (P0.05). This means that male quail with low IgY and medium IgY concentrations are equally good. Testicular weight, semen color and pH were identical at different IgY concentrations. Quails with low IgY concentrations have better sperm consistency, which is related to the weight of the testes, which are heavier in quails with low IgY concentrations than in those with moderate IgY concentrations. This consistency is related to the concentration of sperm in the semen. The result concludes IgY concentrations in male quail did not affect production performance. Quails with low IgY concentration had thicker sperm consistency and higher sperm concentration.

Feeding Effect of Organic and Inorganic Zinc with Vitamin E on Growth Performance and Carcass Quality of Japanese Quail

The research facility of Avian Research &amp; Training (ART) Center (Poultry Production), UVAS, Lahore was selected to investigate the effect of feeding organic and inorganic zinc in addition to vit-E on the growth performance of Japanese quail. for a period of 6 months. The diet formulated by the inclusion of ZnO + ZnI (mg)+VE(IU) as 0+0+0 (A), 25+0+0 (B), 0+15+0 (C), 0+0+12 (D), 25+15+0 (E), 25+0+12 (F), 0+15+12 (G) and 25+15+12 (H), respectively. The effect of zinc and vit-E on growth and slaughter traits of Japanese quail was significant (P&lt;0.05) and it was perceived that in 6 weeks the broiler quails in groups H and F took higher feed (745.44 and 734.70 g/bird), with simultaneous effect on LBW of males (175.35 and 174.50 g), females (198.35 and 197.38 g), average (186.85 and 185.94 g), intestine filled (6.81 and 6.66 g) and empty weights (5.51 and 4.88 g), intestine length (44.87 and 44.75 g), cecal length (16.37 and 16.12 cm), the weight of carcass + giblets (142.01 and 141.48 g), carcass (130.88 and 130.25 g), heart (2.18 and 2.16 g), liver (5.02 and 5.06 g), gizzard (5.62 and 5.21 g), respectively. The dietary Zn + vit-E inclusion significantly (P&lt;0.05) increased the relative length of gut segments, villi height, villus thickness, the villi height to crypt depth proportion in jejunum and ileum and the number of goblet cells in various parts of the intestine of quails. The meat production was significantly higher in female quails than the meat of male quails. This suggested that the organic Zn proved to be better than the inorganic Zn source in addition to vit-E to achieve physiology-related traits in quails.

Effect of dietary sweet almond oil on performance, carcass parameters, blood values and meat quality of Japanese quails.

In this study, the effects of two different levels of sweet almond supplementation (2,500 and 5,000 mg/kg) to Japanese quails’ diets (Coturnix coturnix Japonica) on performance, carcass group, blood values and meat quality were examined. For this purpose, 72 one-day-old Japanese quails were randomly distributed under control and two different experimental groups for 35 days experiment, and their body weight and feed consumption were evaluated. At the end of the study, a total of 8 animals from each group were selected and slaughtered. Hot carcass yield, relative weights of liver, heart, spleen, gizzard, proventriculus and bursa of Fabricius to body weight were determined in slaughtered animals. Total cholesterol, triglyceride, low-density lipoprotein, high-density lipoprotein, and lipase levels in blood serum samples and water holding capacity, pH, malondialdehyde, L, a*, and b* values in breast meat samples were investigated. As a result of the study, it was determined that the addition of sweet almond oil had a positive effect on performance, decreased lipase level in blood serum, and 2,500 mg/kg sweet almond oil supplementation reduced the ratio of proventriculus to body weight. To sum up, it was found that the addition of sweet almond oil to Japanese quail rations had a positive effect on performance and feed consumption; it also appears to reduce blood serum lipase value and proventriculus weight.

Performance, immune response, and meat quality in Newcastle-vaccinated quail fed with colored corn in place of yellow maize.

This work investigated the effects of the usage of colored corn as a replacement for 50% and 100% yellow corn in the diet of Japanese quail. Two hundred and forty-day-old Japanese quails were indiscriminately separated into four experimental groups consisting of six replicates each containing 10 quails. Experimental groups designed: the control group (C) (basal diet-0% colored corn, vaccinated), negative control group (NC) (basal diet-0% colored corn, no vaccine), 50% CC group (basal diet-50% colored corn, vaccinated), and 100% CC group (basal diet-100% colored corn, vaccinated). At the end of the 35-day period, the highest body weight and body weight gain (BWG) were recorded in the 50% CC (P < 0.05). The highest feed intake (FI) was recorded in the 100% CC group, the lowest FI in C (P > 0.05), and the best feed conversion ratio (FCR) in the 50% CC group (P < 0.05). While L* was not affected, a* and b* values were significantly affected by feeding colored corn (P < 0.05). Meat pH, cooking loss (CL), and water holding capacity (WHC) values were significantly affected, and the highest pH and CL values were in the C group and the highest WHC value in NC (P < 0.05). Colored corn had no influence on MDA7th concentration of breast meat. The antibody titers against NDV were significantly superior in the vaccinated groups than in the NC (P < 0.05). In conclusion, the use of colored corn in quail had an affirmative effect on meat quality and growth performance but not on the immune response of quail against NDV.

Sweet Potato Peel as Substitute Dietary Energy Source on the Early Laying Performance, Egg Quality Traits and Yolk Biochemical Composition of Japanese Quails (Coturnix coturnix japonica Temminck &amp; Schlegel, 1898)

This study evaluated the potential of sweet potato peels from different varieties as substitute dietary energy in the early laying performance of Japanese quails. A total of 240 heads of ready-to-lay quails were laid out in a Randomized Complete Block Design (RCBD) and were assigned to the following treatments; ACommercial feeds, B-Home-mixed ration with 10% NISC Sp-35, C- Home-mixed ration with 10% NISC Sp-36, and D- Home-mixed ration with 10% Sp Japonita. The data were analyzed using one-way ANOVA for RCBD, and differences were determined using Tukey's Honestly Significant Difference Test (HSD) at p&lt;0.05. The commercial diet improved hen-day egg production, FCR per dozen eggs, FCR per kilogram egg mass, and eggshell thickness. On the other hand, there were no significant differences (p&gt;0.05) observed in egg weight, egg shape index, dry shell weight, yolk-albumen ratio and yolk total antioxidant activity. The yolk color score of HMR diets was significantly higher (p&gt;0.05) and the yolk cholesterol deposition was lesser than those in the commercial diet. The financial analysis showed that the gross return was highest in the commercial ration. However, HMR diets performed better in terms of net income, return over feed cost, egg-to-feed price ratio, benefit-cost ratio, and return over investment.

The Effect of Gembili Tuber on the Growth Performance of Quail

The aim of this study was to investigate the effect of gembili tuber on the growth performance of quail. The study was used 200 male quail of age 2 weeks. The completely randomized design was used in this study. The treatment of this study consists of T0: control (0% gembili tuber), T1: basal diet + 0,3% gembili tuber, T2: basal diet + 0,6% gembili tuber, T3: basal diet + 0,9% gembili tuber. The parameters of this study were feed intake, body weight gain and feed conversion ratio. The results showed that the administration of gembili tuber has significant effect (p&lt;0,05) on the feed intake, body weight gain and feed conversion ratio of quail. The conclusion of the study was that administration of gembili tubers as a prebiotic increased the growth performance of quail. Keywords: [quail, performance, prebiotic]

Effects of dietary nisin on growth performance, slaughter traits, and thigh meat quality of quail

Abstract In this study, the growth performance, carcass yield, relative organ weight, and thigh meat quality of quail fed with diets containing different amounts of nisin as an active ingredient were investigated. A total of 400 one-day-old Japanese quail chicks were used. The quail were divided into 4 groups with five replicates and were fed with diets without (control) or with nisin (150, 300, and 500Â mg/kg). The study lasted 35 d. At the end of the experiment, a total of 80 quail, 10 males and 10 females of each group, were randomly weighed and slaughtered. After slaughtering, carcass yield, relative liver, heart, gizzard, and proventriculus weights were recorded. Stress factors (Malondialdehyde (MDA), catalase (CAT), total antioxidant status (TAS), the total of oxidant status (TOS), and oxidative stress index (OSI)) were analysed in thigh meat. Increasing levels of nisin did not affect the growth performance of quail (PÂ >Â 0.05). In terms of slaughter weight, the slaughter weight of both males and females differed among the groups (PÂ <Â 0.05). While the highest value in males was observed in the control group, the highest value in females was observed in the N150 group. Only the relative liver weights of males and the relative proventriculus weights of females were statistically different (PÂ <Â 0.01) between treatments. With increasing nisin level, the weight of the liver increased in the males and the weight of the proventriculus in the females. The addition of nisin decreased MDA and OSI values in both males and females, as compared to the control group. Furthermore, CAT and TAS values were found to be significantly higher in the nisin supplemented group than in the control group. As a result, it is concluded that adding nisin to quail feed positively affects TAS, TOS, MDA and CAT values of thigh meat and can prevent the adverse effects that may occur due to stress.
