Effect of Dietary Inclusion of Neem Leaf Powder on Growth Performance, Nutrient Utilization, and Haemato-Biochemical Parameters of Japanese Quail

A feeding trial was conducted to discern the influence of dietary incorporation of neem (Azadirachta indica) leaf powder on growth performance and haemato-biochemical parameters ofJapanese quail for 6 weeks. A metabolic trial was conducted during the last week of the feeding trial to assess nutrient utilization. A total number of 144-day-old chicks of Japanese quail were randomly assigned into four treatment groups, with 36 Japanese quail per treatment having three replicates of 12 birds each. Birds of treatment T1 (control group ) were fed a basal diet (starter and finisher), whereas in treatment groups T2, T3, and T4, the basal diet was incorporated with 0.25%, 0.50%, and 1.00% neem leaf powder, respectively. Results showed supplementation of 0.25% neem leaf powder improved the performance of Japanese quail in terms of body weight gain and performance index during the whole trial period. Nutrient utilization among various treatment groups was similar. The hematological values showed no significant a lterations i n d ifferent groups. Th e biochemical attributes among the treatment groups were similar, but a considerable decrease in the level of cholesterol and glucose was observed with an increasing level of neem leaf powder in the diet. Activities of ALT, AST, and ALP were lowest in the T4 group. It can be concluded that 1 percent neem leaf powder can be supplemented in feed for good health status and desired performance of the birds.

Effect of Termites (Neotermes assamensis) as Protein Source on the Performance of Japanese Quails

Effect of Termites (Neotermes assamensis) as Protein Source on the Performance of Japanese Quails

Mentha piperita as a promising feed additive used to protect liver, bone, and meat of Japanese quail against aflatoxin B1.

The present study was conducted to evaluate aflatoxin B1 (AFB1) detoxification effects of some medicinal plants under both in vitro and in vivo. The in vitro experiment was performed with 25 treatments in 5 replications. The samples of medicinal plants were incubated with AFB1 for 72h, and the toxin residual in the supernatant was determined. The highest aflatoxin elimination was found to be related to peppermint (81%). Thereafter, in vivo experiment was conducted to investigate the effects of peppermint dried leaves, essential oil, and menthol on liver, bone, and meat, as well as the performance of growing Japanese quail fed diet contaminated with AFB1. A total of 640 7-day-old Japanese quails were assigned using a completely randomized design as 2 × 4 factorial arrangement with two levels of AFB1 (including 0 and 2.5mg/kg diet) and four treatments (including no additive; peppermint powder, 20g/kg; peppermint essential oil, 800mg/kg; and menthol powder, 400mg/kg). Those birds fed AFB1-contaminated diet with no additives showed the worst liver health status by considering super oxide dismutase (P = 0.0399), glutathione peroxidase (P = 0.0139), alanine aminotransferase (P < 0.0001), and aspartate aminotransferase levels (P = 0.0512). However, the supplementation of AFB1 contaminated diet with additives improved their liver health status. Menthol receiving birds showed the highest tibia strength, while the birds fed with AFB1-contaminated diet with no additives had the weakest bone strength (P < 0.0001). A significant increase was also observed in malondialdehyde level of meat by dietary inclusion of AFB1, which was well-repressed by the dietary supplementation of peppermint essential oil and menthol (P = 0.0075). Body weight gain dramatically decreased by adding AFB1 to the diet, which was recovered with the dietary supplementation of additives (P = 0.0585). According to the results of the current study, peppermint and its derivatives can be used to suppress aflatoxin effects on the liver, bone, and meat quality and to improve the performance of Japanese quails.

Effects of Substitution of Soybean Meal With Sesame Meal on the Performance of Japanese Quails (Coturnix Coturnix Japonica) and its Impact on Economics of these Quails Raising

Sesame meal (SSM) is locally available and relatively cheaper source of protein having an amino acid composition similar to that of soybean meal (SBM) with the exception of lower lysine and higher methionine contents. Despite its merits it has been under-utilized in quail’s diets. This study was conducted to examine the effects of substitution of SBM with different levels of SSM on production and economic performance of Japanese quails. One hundred eighty day-old Japanese quail chicks were randomly distributed into six experimental groups of three replicates of ten birds each replicate group was placed in a battery. Six of the Groups were given rations with different levels of SSM included; SSM–0 g (control), SSM–50 g, SSM–100 g, SSM–150 g, SSM–200 g and SSM–250 g including SSM per kg of rations. All Rations were fed ad libitum, records of initial body weight; weekly body weight gain and weights of feed offered, consumed and refused were kept. Dressing percentage was determined at the end of experiment. Results indicated that feed efficiency were not affected (P&lt;0.05) in quails fed ration containing 50g of SSM, 100, 150 and 200 with higher (P&lt;0.01) daily weight gain was observed in ration with SSM of 150g per kg of ration. Total feed consumption and dressing percentage were not affected. No significant difference was observed in all groups in terms of cost benefit ratio. It is concluded that SSM can be used as an alternative protein source in Japanese quail diets at inclusion levels up to 150 g/kg without negative effects on performance and carcass traits.

Low dietary inclusion levels of Tenebrio molitor larva meal slightly modify growth performance, carcass and meat traits of Japanese quail (Coturnix japonica).

Insect-derived proteins are a promising, valuable and permitted ingredient for poultry feed. However, more emphasis should be given to their effects on avian species different from chicken, such as quail (Coturnix coturnix), whose rearing represents an important activity. The present paper provides novel information about the impact of graded dietary levels of Tenebrio molitor (TM) larvae meal on quail growth and meat quality. Four diets were formulated with graded inclusion levels of TM, namely 1.65, 3.3 and 6.6 g on 100 g feed (T1.65, T3.3, T6.6, respectively) to partially replace the conventional proteins of a control diet (C). A total of 192 birds were allotted to one of the groups and fed for 35 days. The inclusion of TM meal linearly increased feed conversion ratio, and decreased carcass and breast weight. Texture and water holding capacity of meat were linearly reduced with increasing TM in diet, while fatty acid composition was not affected. However, the meat from quails fed diets including TM was subject to greater thermal damage than the C group; hence further studies are encouraged. TM meal inclusion at higher levels than 1.65% slightly impaired the growth performance of Japanese quails. Negligible effects on physical properties such as colour, texture, cooking loss and also on the fatty acid profile of the raw and cooked meat was found after including TM in quails' diet up to 3.3%. © 2022 Society of Chemical Industry.

Line crossing’s effect on the hatching performance of Japanese quail

Seedlings are one of the factors affecting egg production in quails and the possible efforts to obtain superior seeds include crossing. Therefore, this study was conducted to observe the hatching performance of Japanese quails subjected to line crossing. The materials used were hatching eggs produced by a crossbreeding between the brown male and black female species. Twenty brown male and eighty black female quails were used to produce hatching eggs with a male-to-female ratio of 1: 4. Up to 242 and 239 hatching eggs obtained from Cross 1 and 2 respectively were used. The t-test analysis results were not significantly different (P>0.05), where egg weight = 0.155 and hatching weight = 0.6405. However, the egg index of 0.02617 and the hatching length of 0.02589 were significantly different (P<0.05). At Cross 1, the low hatching mortality was 9.2%, and the high hatching quality was 83.88%. Generally, it was discovered that the products in Cross 1 and 2 have the same performance in terms of hatching weight, mortality, and quality, as well as the egg weight but the line crossing affected the egg index and hatching time. These results are expected to assist the development of a quail breeding strategy in the future.

QUAIL PERFORMANCE WHEN USING DIFFERENT CAGE BATTERIES

The article presents the results of studies on the performance of Japanese quails when using different technological equipment in the JSC “Soligorskaya poultry factory” of the Soligorsky district. It was found that the use of KVI – 4N and OKP – 6 cage equipment contributed to the high performance of quails while reducing feed costs. When using the KVI – 4N and OKP – 6 cage equipment, the profitability of 14.5 – 16.1% was obtained within the trial. Based on this, it can be concluded that rearing quails in KVI – 4N and OKP – 6 cage batteries is economically profitable. This approves using this bird in poultry industries, along with laying hens.

The impact of betaine supplementation in quail diet on growth performance, blood chemistry, and carcass traits

The study aimed to investigate the effect of various doses of betaine supplemented dietary on Japanese quail performance, carcass characteristics, and blood chemistry. Therefore, 400 seven days old Japanese quails were classified randomly into four equal groups. Each group was subdivided into five replicates of 20 birds each. Four rations were formulated using four different betaine levels (0, 0.75, 1.5 and 2.25 g/kg, respectively) for five successive weeks. All groups received feed and clean water ad-libitum. The results of this trial indicated that the feed intake was lowered in groups fed with betaine (p ≤ 0.05) when compared with the control one. The highest weight gain (p ≤ 0.05) was noticed in groups fed diets BS4 (betaine supplementation at the rate of 2.25 g/kg). No difference among groups was observed in body length, shank length, shank diameter, and keel bone length or breast width. Also, the carcass weight and breast yield were highest (p ≤ 0.05) in the group reared on the BS4 diet. In addition, intestinal length and weight were significantly higher (p ≤ 0.05) in groups fed betaine with a concentration of 2.25 g/kg. Fat weight was lower in the group fed BS4 than in the untreated group. Significantly higher values of high-density lipoprotein (p ≤ 0.05) were observed in the group fed BS4. All groups fed a ration containing betaine showed lower levels of liver enzymes such as alanine amino transferase, alkaline phosphatase, and aspartate amino transferase (p ≤ 0.05) and lowered low-density lipoprotein level. The quails fed BS4 had the greatest growth hormones and insulin (p ≤ 0.05) and the lowest thyroxin level. We concluded that dietary betaine supplementation positively impacts Japanese quail growth performance, carcass traits, and blood chemistry.

Effect of L-Carnitine and/or Calf Thymus Gland Extract Supplementation on Immunity, Antioxidant, Duodenal Histomorphometric, Growth, and Economic Performance of Japanese Quail (Coturnix coturnix japonica)

This study aimed to evaluate the supplementation (of drinking water) effects of L-Carnitine (LC) and/or calf thymus extract (TE) on immunity, antioxidant, duodenal histomorphometric, growth, and economic performance of Japanese quail. Six hundred, one day old unsexed quail were divided into four groups, the control group (G1) received plain drinking water, while G2, G3, and G4 were supplemented with LC and/or TE, respectively. The treated groups recorded a significant (p < 0.05) improvement in the final body weight, weight gain, feed conversion ratio, phagocytic activity %, phagocytic index, lymphocytes %, and plasma glutathione level compared to the G1. On the other hand, these supplementations significantly lower the mortality rate %, heterophil %, H/L ratio and plasma malondialdehyde level of the supplemented groups relative to G1. The supplemented groups recorded a non-significant increase in duodenal histomorphometric parameters (villous height, villous width, surface area, and crypt depth) relative to G1. Generally, LC and/or TE improve the values of economic profile (total returns, net profit, total return/total costs %, etc.) in treated groups compared to the control one. In conclusion, L-carnitine supplementation was more effective than TE or their combination with TE in the immunological, anti-oxidative, growth, and economic performance.

Early heat acclimation during incubation improves Japanese quail performance under summer conditions.

Effects of exposing quail eggs to high temperature on the heat tolerance ability and productivity of birds were investigated. Four groups of 600 fertile eggs were randomly selected; the first group was incubated under 37.5°C and the hatched chicks were reared under a gradual decrease in temperature from 35 to 24°C (Control). The second group was exposed to 39.1°C for 2h/day during 4-14days of embryogenesis and the hatched chicks were reared under a gradual decrease in temperature from 35 to 24°C. The third group was incubated under 37.5°C and the hatched chicks were exposed to 39 ± 1°C for 2h/day during 4-14days of age. The fourth group was exposed to 39 ± 1°C for 2h during 4-14days of embryogenesis and the hatched chicks were exposed to 39 ± 1°C for 2h/day during 4-14days of age. The temperature applied changed (P < 0.01) embryo weight and incubation period. Birds exposed to high temperature during brooding had superior growth performance, dressed carcass, body temperature and health traits. Birds subjected to 39 ± 1°C during brooding exhibited decreased feed consumption and body weight gain. Finally, this work suggests that thermal acclimation during embryogenesis might offer a practical method for easing heat stress.

Impacts of onion and cinnamon supplementation as natural additives on the performance, egg quality, and immunity in laying Japanese quail

This study aimed to investigate the effects of dietary dried onion and dried cinnamon supplementation on laying performance, egg quality, serum lipid profile, and immune responses of Japanese quails. A total of 120 laying quails aged 12 weeks were randomly allocated into five groups (24 birds each). Each treatment was replicated 4 times with 6 quails in a completely randomized design. Dietary treatments were as follows: control (basal diet only, without any supplementation); tylosin (basal diet + 100 mg tylosin/kg diet); onion (basal diet + 800 mg dried onion/kg diet); cinnamon (basal diet + 800 mg dried cinnamon/kg diet); and onion + cinnamon (basal diet + mixture of 400 mg each of dried onion and dried cinnamon/kg diet). Cinnamon supplementation improved laying rate, egg numbers, egg mass, and feed conversion ratio of quails compared to the control treatment, followed by tylosin supplementation. Egg shell percentage was higher (P < 0.05) in quails that consumed the onion + cinnamon mixture than those fed only the cinnamon supplemented diet. Serum total lipid content, egg yolk lipids and egg yolk cholesterol were lower (P < 0.05) in birds fed with the supplemented diets than that of the control group. On the other hand, dietary supplements did not affect levels of triglycerides and high-density lipoprotein levels. The dietary supplementation with onion and/or cinnamon reduced serum malondialdehyde levels compared to control treatment. The foot web index was higher (P < 0.05) in the onion treatment than in the other experimental groups. The dried cinnamon and the mixture of dried onion + dried cinnamon treatments showed higher (P < 0.05) immunoglobulin M (IgM) levels than the control treatment. In conclusion, dietary supplementation with natural plant materials such as dried onion and cinnamon can be used to improve the laying Japanese quail performance, egg quality, and immunity.

Effects of coenzyme Q10 on reproductive performance of laying Japanese quail (Coturnix japonica) under cadmium challenge

Japanese quail is an increasingly important bird of economic importance for commercial egg and meat production, particularly in developing countries. There is a need for research aimed at improving efficiency of these birds during stressful challenges, such as oxidative stress. Coenzyme Q10 (CoQ10), a highly functional antioxidant, protects cells against oxidative stress. This study was conducted to determine the effects of CoQ10 on reproductive performance of Japanese quail under cadmium (Cd) challenge. A total of 216 six-wk-old Japanese quail were randomly allocated into 3 groups for an 8 wk experimental trial. The treatments include a negative control (NC): feeding basal diet; a positive control (PC): feeding basal diet and cadmium administration (1 mg/100 g BW, at 10 and 11 wk of age), and (CdQ10): feeding CoQ10 supplemented (900 mg/kg diet) basal diet and Cd administration. At 11 and 13 wk of age, egg production, body weight, mortality, oviduct, and ovarian biometry, were recorded. Histology and histopathology of isthmus and magnum, fertility, hatchability, hatchling quality, and HSP70 mRNA transcript abundance in the utero-vaginal junction (UVJ) were evaluated. Positive control and CdQ10 group had no significant effect on live body weight, stroma weight, follicle size, hatchability, and fertility; however, Cd administration increased (P < 0.01) mortality rate in the PC group compared to the NC and CdQ10 groups. CdQ10 quail produced more eggs and had a higher hatchling quality compared to the PC group (P < 0.01). The thickness and height of isthmus and magnum folds in the CdQ10 group was increased compared to the PC group (P < 0.01) and overall oviduct weight was increased with CoQ10 supplementation (P < 0.01). Compared to PC, the CdQ10 group had a reduction in infiltration of inflammatory cells. Relative abundance of HSP70 mRNA in UVJ was influenced by interactive effect of treatment × time (P < 0.05). In conclusion, dietary supplementation of CoQ10 showed beneficial effects on some reproduction characteristics of female Japanese quail under Cd-induced oxidative stress.

The carcass and meat quality characteristics of Japanese quail fed a diet supplemented with powdered Lactuca seriola leaves

The present study was aimed to evaluate the effect of dietary supplementation with Lactuca serriola leaves on growth performance, carcass characteristics, meat quality, and its antioxidant stability of Japanese quails. A total of eighty growing quails (1-week old) were distributed into 2 equal groups consisting of 40 birds (5 replicates of 8 birds each). The first group was fed a basal diet without Lactuca serriola leaves (0 g.kg-1 diet) and the second group received diets containing 20 g.kg-1 Lactuca serriola leaves. At age of 6 weeks, quails were slaughtered for meat and carcass examinations. The growth performance for the quails fed with Lactuca serriola leaves diet was similar to that of a control group. Carcass measurements, physical properties, and chemical composition of quail breast meat did not differ between the control and experimental group. However, the inclusion of Lactuca serriola leaves significantly increased the omega-3 polyunsaturated fatty acid content and improved breast meat lipid stability during postmortem refrigerated storage compared to the control diet. In conclusion, dietary supplementation of Lactuca serriola leaves can improve the performance of Japanese quail enrich its meat with an omega-3 polyunsaturated fatty acid, and reduce lipid oxidation during storage.

Effect of different level of Tryptophan and methyl group donors on the performance of Japanese quail fed diets contaminated with aflatoxin B1

The experiment was carried out to investigate the effect of tryptophan, melatonin and dimethylglycine on the growth performance and meat quality of Japanese quails fed diets contaminated with aflatoxin B1 toxin. In this experiment, 680 Japanese quail from 7 to 35 d of age was allotted to 17 treatments and 4 replicates with 10 Japanese quail in each were performed using a central composite design. The performance of birds was calculated on a weekly basis and at the end of the experiment; the amount of Malondialdehyde in meat was examined. the results showed that tryptophan increase weight gain (p < 0.05) and melatonin had an increased effect on feed intake (p < 0.05). The effect of tryptophan and as well as the interaction of tryptophan and dimethylglycine reduced the amount of malondialdehyde in meat (p < 0.05). The results obtained from this research states that dietary supplementation with Tryptophan and methyl group donors have good antioxidant capacity to reduce aflatoxin B1 poisoning on growth performance and Malondialdehyde content of meat, and the use of these supplements in the diet of Japanese quail seems desirable.

The Effect of Using Different Levels of American Cockroach (Periplaneta americana) powder on Productive and Physiological Performance of Japanese Quail (Coturnix japonica)

This study aimed to investigate the effect of using different levels of American cockroach (Periplaneta americana) powder on productive and physiological performance of Japanese quail (Coturnix japonica). One hundred and thirty-five, 45 days-old of Japanese quail females were randomly divided into three groups (45 females for each). Each group has three replicates (15 females per each). The groups were included: The first group was fed on experimental diet included with 0 % of insect powder and 6% of protein concentration as the control. The second group was fed on experimental diet included with 3% of protein concentration and 3% of insect powder. The third group was fed on experimental diet included with 0 % of protein concentration and 6% of insect powder. The results showed no significant in the egg weight, egg mass, feed conversion ratio and mortality among groups. The birds in the third group were recorded a significant increase (P ≤ 0.05) in the egg production (%), on the other hand, it recorded a less value in the feed intake compared to other groups. The results of relative weight of ovaries and oviducts showed the birds in the third group were recorded a significant increase (P ≤ 0.05) compared to other groups. On the other hand, the second group was recorded a significant increase (P ≤ 0.05) compared to first group (control). The results were indicated no significant in the levels of estrogen hormone among groups. While, the results of the levels of follicle stimulating hormone and luteinizing hormone were indicated a significant increase (P ≤ 0.05) in the third group compared to other groups. In addition to, the second group was recorded a significant increase (P ≤ 0.05) compared to first group (control). In conclusions, so far proves the potential of the American cockroach (P. americana) meal for use in quail production systems. American cockroach (P. americana) food based feed can completely replace protein sources by 100 per cent without negative effect on the productive performance of quail and, in some ways, can achieve better than conventional protein based feeds such as protein concentrations. On the other hand, the American cockroach (P. americana) meal improved physiological performance of quail.

The Effect of Adding Different Types of Vegetable Oils and Waste Frying Oil on the Productive and Reproductive Performance of Japanese Quail

EFFECT OF DIFFERENT ENERGY LEVELS OF COCOA HUSK-BASED DIETS ON PRODUCTIVE PERFORMANCE OF JAPANESE QUAILS

Cocoa husk-based diets were used to assess the effect of different energy levels on the growth performance, economics of production and dressing percentage of Japanese quail (Coturnix coturnix japonica) in South Western Nigeria. The assessment period was at 4 to 7 weeks of age. Four isonitrogenous (22% crude protein) diets incorporating graded levels (0, 3, 5, 7.0 and 14%) of cocoa husk meal (CHM) as replacement for maize, were used in the trial which involved 360, 3-week-old quail chicks. The diets had the followjng corresponding ME levels, viz: Diet 1, 2800; Diet 2, 2700; Diet 3, 2600 and Diet 4, 2500 kcal/kg. Each dietary treatment was similar (P &gt; 0.05) among the diets while feed intake was higher (P &lt; 0.05) on Diet 4 than Diets 1 and 2. Caloric intake, feed conversion and calorific efficiency did not differ significantly (P &gt; 0.05) among the treatments. Though feed cost and feed price/100 kcal ME decreased numerically across treatment, feed cost/kg gain was similar (P &gt; 0.05). Dressing percentage was not influenced (P &gt; 0.05) by dietary energy levels. Results of this study indicated that dietary energy levels of 2500 to 2800kcal/kg ME of cocoa husk-based diets are suitable for overall acceptable productive performance of Japanese quails during 4 – 7 weeks of age in South Western Nigeria.

GROWTH PERFORMANCE AND MICROFLORA IN GROWING QUAIL FED DIETS SUPPLEMENTED WITH Lactuca serriola POWDER

The aim of the current study was to assess the influence of Lactuca serriola supplemented diet on performance, carcass characteristics and intestinal microbiota count of Japanese quails. A total of eighty birds of quail (one week of age) were divided into 2 groups of 40 birds each (five replicates of eight birds each). In the first group, the birds were fed a basal diet without Lactuca serriola, while the birds in the second group were fed diets containing 20 g Lactuca serriola /kg feed. Birds in both groups were fed for five weeks. Quails were slaughtered in order to study intestinal microbiota count and carcass characteristics at six weeks age. The results showed that quails fed Lactuca serriola had higher growth performance including body weight in comparison with the control group. The inclusion of Lactuca serriola had significantly higher lactic acid bacteria count and lowest level of E. coli and Salmonella enterica count than the control group. However, Lactuca serriola did not affect carcass measurements. Thus, supplementation of Lactuca serriola can improve the performance of Japanese quail and used as a new feed additive to balance gut microbiota

Effect of egg weight and oviposition time on hatchability and post hatch performance of Japanese quail (Coturnix coturnix japonica)

A total of three hundred (300) Japanese quail eggs were used to study the effect of oviposition time and egg weight on hatchability and post-hatch performance. The eggs were grouped into two (2) of 150 eggs based on the oviposition time of Morning and Afternoon. The eggs in each group (150) were further sub-grouped based on the egg weights of 8 to10 grams designated as small sized and 10.1 to 12 grams designated as big size in a 2 x 2 factorial design trial of 4 treatments. Each treatment had seventy five (75) eggs each with three replicates. The four treatments groups were; Big Morning, Small Morning, Big Afternoon, Small Afternoon. Each treatment group was replicated three times with each replicates consisting of twenty-five (25) eggs. Hatchability parameters were determined during incubation period of 18 days. The quail chicks were fed ad-libitum and the post- hatch performance was studied for eight (8) weeks. The data generated were subjected to a one-way analysis of variance. Oviposition time and size of the egg significantly (p&lt;0.05) affected the average hatch weight. The effect of interaction of oviposition time and egg size on post-hatch performance did not have any significant (p&gt;0.05) influence. Oviposition time had a positive correlation (p&lt;0.05) with egg weight, egg weight loss, percent egg weight loss and fertility percentage but negatively correlated with average hatch weight and hatchability percentage. Meanwhile egg size had a positive significant (p&lt;0.01) correlation with average hatch weight. It was concluded that eggs ranging between 10.1 to 12 grams will produce higher hatch weight. However, setting of Japanese quail eggs ranging between 8 to 12 grams irrespective of oviposition time could not affect post-hatch performance of the chicks.

Growth response, carcass characteristics and egg laying performance of Japanese quail (Coturnix coturnix japonica ) fed diets containing varying levels of fermented cassava (Manihot esculenta ) peel meal

A two phased experimental study was conducted on 300, two-weeks-old Japanese quails to determine the effect of feeding diets containing varying levels of fermented cassava (Manihot esculenta ) peel meal on the growth performance, carcass characteristics and egg production of Japanese quail ( ). Japanese quails with mean initial body weight of 26.67 g and of mixed sexes were used. Fermented cassava peel meal (FCPM) was prepared by soaking fresh cassava peels in water (that is twice its weight) for three days. Thereafter, the peels were put in a jute bag and kept for 12 hours under a hydraulic press; sundried for a few days and milled using an attrition mill. During the growing phase, the birds were randomly allotted to four dietary treatments with 75 birds per treatment, each replicated three times, with the diets containing FCPM replacing 0, 25, 50 and 75 % maize to form diets T , T , T and T respectively. The diets were isonitrogenous, containing 24 % crude protein, and fed to the experimental birds for six weeks. Data were collected on feed intake, growth performance and carcass characteristics. The laying phase involved 120 female quails from he growing phase that were sexed to retain only the females. They were then allotted to four dietary treatments of three replicates per treatment; with 10 birds per replicate. The birds were fed the experimental diets containing FCPM replacing 0, 25, 50 and 75 % maize for eight weeks, and data were collected on egg production and egg quality parameters. Results show significant (p&lt;0.05) differences in daily feed intake and nutrient digestibility among the treatments, while daily weight gain and feed conversion ratio (FCR) were not significantly (p&gt;0.05) different, during the growing phase. For the laying phase, there were no significant (p&gt;0.05) differences in daily feed intake, hen day production (HDP) and all the egg quality traits determined. Therefore, it can be concluded that dietary maize could be replaced with FCPM up to 50 % and 75 % in growing quails without any deleterious effects on growth performance and carcass characteristics respectively; whereas it can replace up to 75 % in the diet of laying Japanese quails without any adverse effect on egg production and egg quality traits.
