Parede celular de levedura em dieta para codornas japonesas na fase de postura em diferentes densidades de criação

Abstract The objective of this study was to measure the zootechnical performance and egg quality of Japanese quails housed at different densities and fed diets containing yeast cell walls (YCWs). Five hundred and seventy-six quail (Coturnix coturnix japonica) were distributed at 43 weeks of age, and 76% were laid, with an initial weight of 158.50 ± 5.41 g, in a completely randomized design in a 3 × 2 factorial arrangement (three YCW levels: 0, 500, and 750 g.ton−1 and two housing densities: 81.5 and 92.4 cm2/quail), with six replicates of 17 and 15 quail per experimental unit, respectively. The following parameters were evaluated: feed intake, egg production/bird/day, egg production/housed quail, marketable egg production, egg mass, feed conversion per dozen eggs, egg mass and viability, egg weight, specific egg weight, percentage of yolk, albumen and shell, and shell thickness. The means of the three cycles of 21 days were subjected to analysis of variance using the statistical software Sisvar. There was no significant interaction effect between YCW inclusion level and cage density on zootechnical performance parameters or egg quality, except for egg weight, which suggested that YCW addition, regardless of cage density, did not affect the results. It was observed that the eggs of quails housed in cages with 92.4 cm2/bird feed and 500 g.ton1 YCW had greater egg weights. Shell thickness was independently influenced by cage density, and the lowest density (92.4 cm2/bird) promoted greater shell thickness. The inclusion of 500 g.ton1 of yeast cell wall material in the diet of Japanese quails housed at a density of 92.4 cm2/bird improved egg weight and shell thickness without negatively affecting the other parameters of egg quality or zootechnical performance.

Spirulina in diets of Japanese quail: Productive performance, digestibility, and egg quality

The present study evaluated the effects of dietary inclusion of spirulina on productive performance, nutrient utilization, and egg quality of Japanese quails. One hundred twenty quails were included in a completely randomized design with four treatments and five replicates. Treatments consisted of a control diet and three diets containing 0.3, 0.6, or 0.9% of spirulina powder. Spirulina inclusion had no effect (p > 0.05) on the productive performance, digestibility coefficients of dry matter and ether extract, calcium and phosphorus retention, weight and pH of the eggs, yolk index, albumen quality, and eggshell thickness when compared with the control diet. However, crude protein consumption was higher (p < 0.05) and the digestibility coefficient of crude protein was lower (p < 0.05) in birds in the 0.9% and 0.3% spirulina inclusion groups, respectively. The weights of the yolk and eggshell were improved (p < 0.007) by the inclusion of 0.6% and 0.9% and 0.9% spirulina, respectively. Quails fed diets containing 0.3% and 0.6% spirulina exhibited lower specific gravity of eggs (p < 0.019) than those fed diets containing 0.9% spirulina. Therefore, spirulina inclusion at 0.9% improved the eggshell quality and reduced the total lipid levels in the yolks.

Quality of Japanese quail eggs according to different storage periods and temperatures

The objective was to evaluate the quality of Japanese quail eggs stored at room temperature (26.8ºC) and under refrigeration (10.9ºC), for different storage periods (0; 5; 10; 15; 20; 25 and 30 days). A total of 196 quail eggs were assigned to different treatments in a factorial arrangement of 2 (temperatures) x 7 (storage periods), with 3 replications and 4 eggs per experimental unit. Data were subjected to regression analysis of parameters as a function of storage time at room temperature and under refrigeration. There was a reduction in egg weight, albumen weight and height, yolk height and egg yolk index with increasing storage period as a function of temperatures (p < 0.05). Eggs at room temperature showed a reduction in albumen index, while eggs under refrigeration showed a quadratic behavior (p < 0.05). Storage days promoted a quadratic response in albumen and yolk pH (p < 0.05) of eggs at room temperature. Eggs at room temperature floated from the 15th day of storage. When stored at room temperature, quail eggs show a sharp decrease in internal quality during storage for up to 30 days. Refrigerated storage is recommended.

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.

The Quality of Japanese Quail Eggs After Administration of Bifidobacterium sp. and Guazuma ulmifolia Leaf Extract

This study aimed to determine the effect of Bifidobacterium sp. and Guazuma ulmifolia leaf extract on Japanese quail egg production, including egg mass, haugh unit (HU), and egg yolk colour. A total of 96 quails were in the early stages of production, which were randomized into four treatments and six replications. The treatments were (T0) without Bifidobacterium sp. and G. ulmifolia leaf extract, (T1) 0.2% Bifidobacterium sp., (T2) 0.2% G. ulmifolia leaf extract, and (T3) 0.2% Bifidobacterium sp. + 0.2% G. ulmifolia leaf extract. Egg mass data was collected in the third and fourth week of the treatment period, while the HU data and egg yolk colour were carried out on the last week of the treatment period. The treatment groups showed significant differences in egg mass. Groups T2 and T3 showed significant differences in egg yolk colour. The combination of feed additives can increase the value of HU but not significantly (p&gt;0.05). In conclusion, the combination of 0.2% Bifidobacterium sp. and 0.2% G. ulmifolia leaf extract in drinking water can produce the highest egg quality.

PRODUCTION PERFORMANCE AND EGG QUALITIES OF JAPANESE QUAIL (Coturnix coturnix japonica) LAYERS FED DIETS WITH VARYING PROTEIN LEVELS SUPPLEMENTED WITH OR WITHOUT TURMERIC RHIZOME POWDER

This experiment investigated the effects of varying crude protein levels (CPL) supplemented with or without Turmeric Rhizome Powder (TRP) on laying performance and egg quality of Japanese quails. A total of one hundred and ninety two 10-weeks-old laying Japanese quails were randomly distributed into six dietary treatment groups (3 x 2 experimental arrangement) with four replicates per group (8 birds per replicate) in a completely randomized design. Dietary treatments were: A (24%CP), B (21%CP), C (18%CP) without TRP while D, E and F contains 24%CP+0.5%TRP, 21%CP + 0.5%TRP and 18%CP + 0.5%TRP, respectively. Data were taken on productive performance, egg quality and egg proportions for 10 weeks. The main effect showed that quails on 24 and 21% CPL diet had elevated (P&lt;0.05) hen egg day production (HDP). Feeding of quails with 18% CPL diet resulted in increased (P&lt;0.05) feed cost /kg egg and revenue was higher (P&lt;0.05) with the use of 21 and 24% CPL diet. The main effect shows that turmeric supplementation enhanced (P&lt;0.05) yolk colour. The interactive effect showed that quails fed diets containing 24 and 21% CPL with or without TRP supplementation had increased (P&lt;0.05) HDP. Feed cost/kg egg increased (P&lt;0.05) for quails fed diet with 18% CPL diet with or without TRP supplementation. The revenue increased for quails fed 21% CPL diet with TRP supplementation. The feeding of diets containing 21 and 18% CPL with TRP supplementation resulted in enhanced (P&lt;0.05) yolk colour (4.36 and 4.43) respectively. Egg proportions were not influenced (P&gt;0.05) by CPL or TPL. It was concluded that TRP supplementation influenced HDP, increased revenue with 21% CPL diet and enhanced egg yolk colour.

Shark liver and flaxseed oils as alternatives to soybean oil in the lipid quality of Japanese quail eggs

PurposeThe objective of this study was to assess the incorporation of polyunsaturated omega 3 and omega 6 fatty acids in the eggs of Japanese quails (Coturnix coturnix japonica) fed with soybean, flaxseed and shark liver oils, as well as to assess their effects on the chemical composition and lipid quality of the yolks.Design/methodology/approachThe total of 252 units of quails were distributed in a completely randomized design with seven treatments and six replications, totaling 42 experimental design units. The sources of oils and their inclusions in the experimental diet were 2% of soybean oil (S), 2% of flaxseed oil (L) and 2% shark liver oil (T), obtained from the species Carcharhinus acronotus, and the mixtures of 1% S + 1% L (SL); 1% S + 1% T (ST); 1% L + 1% T (LT) and 0.67% S + 0.67% L + 0.67% T (SLT).FindingsThe proximate composition of the egg yolk was not changed to the supplementation of lipid sources added in quail diet. The total replacement of soybean oil by shark liver oil reduced the cholesterol content in the yolk by 19% (T = 282.97 mg cholesterol/100 g egg) and the addition of flaxseed oil produced eggs with greater amount of polyunsaturated fatty acids (PUFAs) (LS = 18.32%). The treatments with flaxseed oil and its mixtures (soybean oil + flaxseed oil and flaxseed oil + shark liver oil) effectively contributed to reducing the ω-6:ω-3 ratio and enriching the quail eggs with PUFAs, especially linolenic acid (18: 3n3c) and EPA (20: 5n3c).Originality/valueThus, manipulation in the diet of quails enriched the content of essential PUFAs and reduced the cholesterol content in the yolk. The flaxseed oil was the lipid source that influenced to improve the quality of the egg yolk. These results have practical applicability for the quail egg industry.

Thermal comfort thresholds for Japanese quails based on performance and egg quality.

Knowledge of the effects of thermal stress on Japanese quails helps support decision-making regarding the management of climate control systems. Thus, the objective of this study was to evaluate the performance and egg quality of Japanese quails subjected to different air temperatures (tair) and to propose thresholds for the temperature-humidity index (THI), the Black globe humidity index (BGHI), and enthalpy (H). Two experiments (21days each) were conducted in four climate-controlled wind tunnels. In the first experiment, tair was 20, 22, 24, and 26°C, and in the second, tair was 20, 28, 30, and 32°C. The relative humidity (RH) and air velocity were 60% and 0.3ms-1, respectively. To define the comfort thresholds, the productive performance of the birds, water intake, and egg quality were evaluated. No differences were observed (p > 0.05) for the performance-related variables, except for feed intake, which decreased (p < 0.05) as tair increased, and water intake, which increased (p < 0.5) by 15.9% starting at 28°C. For experiments 1 and 2, with tair at 20°C (tair,obs = 20.8 and 21.3°C, respectively), there was evidence of cold stress. The shell thickness, Haugh unit, and internal quality unit were negatively influenced (p < 0.05) by tair starting at 28°C. Japanese quails were able, within certain limits, to adapt to continuous thermal stress. The Japanese quails thermal comfort intervals recommended for THI, BGHI, and H are 68.4 to 76.2, 69.1 to 77.2, and 50.5 to 67.2kJ kgdry air-1, respectively.

Nutraceutical effects of organic Selenium and vitamin E supplementation on performance, antioxidant protection and egg quality of Japanese quails (Coturnix japonica)

This study evaluated the nutraceutical effects of organic Selenium and vitamin E supplementation on performance, egg quality and antioxidant protection of Japanese quails. Forty-two posture cages with six birds each were randomly set in seven treatments. Each treatment consisted of the addition of 200 IU of vitamin E/kg of feed and increasing levels of organic Selenium. Significant differences were found in α-Tocopherol deposition, enzymatic activity of glutathione peroxidase (GSH-Px) and oxidative bioindicator malondialdehyde (MDA) in egg yolk with vitamin E supplementation. We concluded that supplementing 200mg of vitamin E and 0.30 ppm organic Selenium did not affect bird performance, but improved egg quality and shelf life. Highlights: This study evaluated the nutraceutical effects of organic selenium and vitamin E supplementation on egg quality of Japanese quails. Forty-two posture cages with six birds each were randomly set in seven treatments. Each treatment consisted of the addition of 200 IU of vitamin E/kg of feed and increasing levels of organic selenium. Supplementing 200mg of vitamin E and 0.30 ppm organic selenium did not affect bird performance, but improved egg quality and shelf life.

The purpose of this 10-week study was to examine the impact of fermented dragon fruit peel (Hylocereussp) juice in drinking water on the performance and quality of Japanese quail eggs. A total of 200 two-week-old quails were included using a completely randomized design that included five treatments and four replications, each with ten quails. R0 = drinking water without dragon fruit peel juice; R1 =drinking water containing 1% dragon fruit peel juice; R2 =drinking water containing 1% fermented dragon fruit peel juice; R3 =drinking water containing 3% dragon fruit peel juice; R4 =drinking water containing 3% fermented dragon fruit peel juice. The performance and quality of the Japanese quail eggs were measured.The study’s findings revealed that treatments R2, R3, and R4 significantly improved quail performance, body weight gain, final body weight, FCR, and egg quality, weight, HU, and yolk color when compared to R0.&#x0D; Keywords: dragon fruit peel juice, performance, eggs quality, Japanese quail

THE EFFECT OF BEE BREAD ON THE EGG QUALITY OF JAPANESE QUAILS DURING LAYING PERIOD

The aim of the study was to detect effect of supplementation bee bread in diet on Japanese quail’s egg quality during laying. The quails were divided into four groups as follows: E1 with addition of 2 g, E2 with 4 g, E3 with 6 g bee bread per 1 kg of feed mixture and the control without additives (C). The groups were kept under the same conditions. The supplementation of BB into diets affected the laying parameters in favor of the experimental groups. The average egg weight was significantly (P≤0.05) affected by diet and by age. E2 had significantly lower egg weight than C and E3. The animals had significantly lower egg weight regardless of the experimental group at age of 16 weeks. The most significant differences between the C and E groups were in eggshell thickness. All experimental groups had a thinner eggshell than C. The average egg weight was significantly (P≤0.05) affected by diet and by age. The weight of the egg, yolk and albumen were significantly lower at the beginning of laying (P&lt;0.01). We recorded significant differences between the control group and some experimental groups in the weight and width of the albumen; in the percentage of albumen and yolk between the control group and E2 (P&lt;0.05). The control group had darker eggs (9.58oHLR) than experimental groups (from 8.89 to 9.34oHLR). We can conclude that the BB supplementation in diet had significant effect on selected parameters of egg quality of Japanese quails, mainly on the eggshell thickness.

Influence of dietary protein levels and some cold pressed oil supplementations on productive and reproductive performance and egg quality of laying Japanese quail

The present study was carried out to examine the effect of dietary protein levels (18, 20, and 22%) and addition of cold-pressed oils (no addition, 1 g thyme, 1 g oregano, and 0.5 g thyme + 0.5 g oregano /kg diet) on the productive and reproductive performance and egg quality of Japanese quail at the laying period. 324 mature ten-week-old Japanese quails (216 females and 108 males) were used. Quails were randomly distributed to 12 treatment groups, 27 in each group, with 3 replicates of 9 quails (6 females and 3 males) per group. Feed conversion ratio (FCR) significantly improved in the layers fed with the diets containing 20 or 22% CP in all experimental periods, except in 3- to 4-month-old birds. The diets supplemented with thyme only or interaction with oregano improved FCR significantly compared to the control or oregano -administered group in all experimental periods, except in 2- to 3-month-old birds. Dietary supplementation with thyme oil caused the egg number and egg mass to increase significantly in all experimental periods compared to the other dietary groups. Fertility percentages were significantly higher in the groups which had oregano than in the control group. Dietary supplementation with thyme oil significantly increased the egg number (P&lt;0.05) and egg mass (P&lt;0.01) in all experimental periods compared to other dietary groups. Fertility and hatchability percentages were not significantly affected due to varying dietary protein levels throughout the experiment. In conclusion, the quails fed with a diet containing 20 to 22% CP or supplemented with oregano or thyme oil exhibited an improved productive and reproductive performance without any detrimental impacts on the other parameters studied.

Impact of Protein Source and Its Levels on Egg Production and Egg Quality of Japanese Quail (Coturnix coturnix japonica)

Fish and soybean meal are known as common utilized crude protein sources in poultry diets. Quail birds often need higher requirements of dietary protein which influences its productive performance. The aim of the experiment is to determine the impact of protein source with different levels on egg production and egg quality characteristics. The experiment was carried out at animal production dept., University of Duhok, Kurdistan Region- Iraq, during spring 2020 for 56 days. The birds were divided into two main groups (fish meal and soybean meal) with three levels of crude protein (CP) as sub groups (20%, 23% and 26%). At 35 days of age, 240 quails were sexed and distributed on wire cages as four replications for each protein level within each group (treatment) as family (8 pullets with 2 cocks). The investigated characters were; Egg weight (EW), egg number (EN), egg mass (EM), egg quality characteristics (shape index, high, weight and diameter of both, yolk and albumen, egg shell thickness and weight and Haugh units); feed intake (FI), feed conversion ratio (FCR), hatchability and fertility percentage. The main results were as follows; EW, EM and most of egg quality characteristics did not show significant difference (P&gt;0.05) either by source of protein or its levels; also, FI and FCR did not differ significantly (P&gt;0.05) by the effect of protein source; while EN, FI and FCR were affected significantly (P≤0.05) by CP level. To conclude, there was no obvious trend for the effect of both CP source and level on early egg yield and egg quality in J. quail.

Physiological variables and egg quality from quails (Coturnix coturnix japonica) that received water with increasing levels of NaCl and under different temperatures

The objective of this study was to evaluate the influence of water salinity and ambient temperature on the physiological variables and the quality of Japanese quail eggs (Coturnix coturnix japonica) in the laying phase. The quails received water with increasing levels of salinity (1.5, 3.0, 4.5 and 6.0 dS m-1) and were kept in climatic chambers under two different temperatures (24ºC and 32ºC). The design used was completely randomised, with a 2 x 4 factorial arrangement (temperatures and salinity levels), with six replicates of eight birds each. Data were submitted for analysis of variance and the means were compared by the Tukey test at 5%. There was no influence (P &gt; 0.05) of water salinity levels on the physiological variables nor on the quality of the birds’ eggs. At 32oC there was an increase (P &lt; 0.05) in respiratory rate, cloacal and body surface temperature of the birds, and a slight reduction (P &lt; 0.05) in the weight of eggs, shells, and percentage of shell. For laying quails, water with salinity levels of up to 6.0 dSm-1 can be used and the birds can be raised in an environment with temperatures up to 32ºC.
