Background and Aim: Copper (Cu) is a vital mineral involved in various physiological and biochemical processes, growth, and productivity of animals and birds. Birds can absorb only a small fraction of Cu and most is excreted, contaminating soil and aquatic environment which is toxic for microorganisms, plants, animals, and humans. This study evaluated the possibility of use of organic and nanoparticles sources of Cu to reduce supplementation level without compromising the performance of breeder hens. Materials and Methods: A total of 224 Swarnadhara breeder hens were divided into seven treatment groups having four replicates in each. The basal diet (control) containing 20 ppm inorganic Cu (100% of standard recommendation) and six test diets containing 20, 15, and 10 ppm (100, 75, and 50% of standard recommendation) from Cu organic source, and 15, 10, and 5 ppm (75, 50, and 25%) from Cu nanoparticles (Cu-NP), were prepared and offered to respective treatment groups for a duration of 20 weeks. Results: The hen day egg production, hen housed egg production, feed conversion ratio egg mass, albumen index, yolk index, total fat content, and color score were not affected by the source and inclusion level of Cu. The feed intake was significantly (p<0.05) lower at 15 ppm and egg weight was significantly (p<0.05) higher at 10 ppm Cu-NP supplemental level, but was non-significant in other treatment groups compared to control. The body weight gain were significantly (p<0.05) higher at 20 ppm organic and 15 ppm Cu-NP inclusion. The egg shape index and Haugh unit were significantly (p<0.05) lower at 10 and 15 ppm of Cu-NP inclusion level, respectively. The shell thickness was improved (p<0.05) at 20 and 15 ppm organic and 15 and 10 ppm Cu-NP inclusion level. The egg fertility rate was shown to be significantly (p<0.05) higher at 20 ppm organic Cu inclusion group, but the hatchability based on total number of eggs set improved (p<0.05) at 20 and 15 ppm organic Cu inclusion level while all treatment groups were comparable to control. The hatchability of fertilized egg and chick's quality significantly (p<0.05) improved, while embryonic and chick mortality after hatching before-sorting was significantly (p<0.05) reduced at 15 ppm of Cu-NP inclusion group. Conclusion: It was concluded that the inorganic Cu can be replaced with 50% of organic or 25% of nanoparticles form of Cu without jeopardizing the breeder hens' productivity, egg quality characteristics, hatchability, and progeny.

This experiment was carried with Japanese quails in the egg production phase with the objective of determining the requirements of digestible methionine + cystine (M+C) for higher production and egg quality. A total of 240 Japanese quails were distributed in a randomized complete block design. The basal diet was supplemented with different DL-methionine levels, corresponding to digestible methionine + cystine levels of 0.55, 0.61, 0.67, 0.73 and 0.79%. The characteristics analyzed were feed intake (g/quail/day), egg production (%), egg weight (g), egg mass (g/quail/day), feed conversion (dozen eggs/egg mass and kg feed/dozen eggs), egg shell (% and g), albumen (% and g), yolk (% and g) and specific gravity (g/cm³). The digestible M+C level for Japanese quails was 0.696% in the diet, corresponding to a daily intake of 186.7 mg/quail.

Abstract The increasing demand for healthy and low fat poultry products by consumers has necessitated the use of natural growth promoters to enhance hens’ laying performance. This study investigated the reproductive response and egg quality traits of pullet chickens fed dietary turmeric (Curcuma longa) and ginger (Zingiber officinale) powder. Five hundred and four pullets were assigned basal diet (G 0 T 0 ) or basal diet supplemented with 1.5 (G1.5) and 3% (G3) ginger or 1.5(T1.5) and 3% (T3) turmeric to investigate the reproductive responses and egg quality traits of pullet chickens during a 60 week trial period. Data were collected on egg and laid out in a Completely Randomized Design in a 2 x 3 factorial arrangement. Hen-day and hen-housed egg production, egg mass, feed conversion ratio and age at first lay were significantly (p<0.05) affected by phytobiotic type. The best (p<0.05) hen-day, hen-housed, egg mass, FCR, earliest age at first lay and least weight at first lay were obtained in birds placed on 1.5% ginger ration. Percentage mortality was not significant except at the different inclusion levels and was least among birds fed 1.5% phytobiotic inclusion levels. The highest (p<0.05) value for egg length, egg width, egg shape index, albumen weight and yolk colour were obtained in birds fed 3% turmeric diets. Internal egg qualities were most enhanced by turmeric inclusion while dietary ginger improved the external qualities. The study concluded that dietary ginger and turmeric enhanced reproductive performance and egg quality of egg-type chickens fed over their commercial production lifespan without impairing their overall well-being.

This research was carried out to evaluate the effects of different levels of multi-enzyme addition to the quail diets on performance, egg internal and external quality parameters and some serum parameters of laying quails. In the experiment, a total of 96 Japanese quails at the age of 10 weeks were randomly distributed to six treatment groups with four replicates contained with four quails in each subgroup. The experimental diets were prepared by adding 100, 500, 1000, 1500 or 2000 mg/kg multi-enzyme to the basal diet without enzyme. Body weight gain, egg production, egg weight, egg mass, feed intake and feed conversion ratio were not affected by multi-enzyme levels in the experiment. In addition, the effects of the treatments on the internal and external quality parameters of the eggs were not found to be significant, except for the eggshell thickness. Eggshell thickness increased significantly at the 1000 mg/kg multi-enzyme level. While glucose, creatinine and cholesterol were not affected from serum parameters, the AST was increased at the 100 mg/kg and albumin, globulin, total protein, calcium and phosphorus concentrations were increased with the addition of 2000 mg/kg multi-enzyme level. According to these results, it was seen that high level of multi-enzyme addition to the diet (2000 mg / kg) improved the serum parameters of quails, but this improvement in serum parameters did not reflect on the performance and egg quality of quails.

This study was carried out to determine the influence of diets including different levels of protein and supplemented with probiotic-enzyme mixed on performance parameters and eggshell quality in laying quails. Japanese quails (n=120), 10 wk of age, were divided into 6 dietary treatment groups and the experiment lasted for 10 weeks. In each experiment group there were 5 replicates, and in each replicates there were 4 birds. Six diets, arranged a factorial design with three protein levels (16, 18 and 20 (control) %) and two levels of supplemented probiotic-enzyme mixed (0.0 and 1.0 g/kg) were used. Dietary crude protein levels and supplementation of probiotic-enzyme did not effect on the body weight gain, egg mass, feed intake, feed conversion, cracked egg yield, specific gravity and shell strength. However, egg production, eggshell thickness and eggshell weight were significantly increased by the addition of probiotic-enzymes mixed. Egg weight in group containing 18% crude protein was significantly higher than the containing 16% crude protein group. Results of the present study indicated that laying quails should be fed 18% crude protein and 1.0 g/kg of supplemental probiotic-enzyme mixed improved egg production and eggshell quality.

Background and Aim: The use of antibiotics as growth promoters in the feed of poultry, has contributed to an increase in the antimicrobial resistance of foodborne pathogens worldwide. Hence, the development of new effective alternatives to antibiotics that do not hinder productivity is imperative. For this, the aim of the present study was to determine whether oregano essential oil (OEO) extracted from Lippia origanoides is a suitable alternative to growth-promoting antibiotics (GPAs) for improving the performance, egg quality, and intestinal morphometry of ISA Brown laying hens. Materials and Methods: A total of ninety-six 70-week-old ISA Brown laying hens were randomly assigned to four treatment groups with four replicates per treatment and six hens per replicate. The treatments consisted of four different diets that were formulated according to the nutritional requirements of the genetic line and the production phase with and without the addition of GPA and OEO: NC, which did not contain OEO or GPA; GPA, which included 50 ppm zinc bacitracin as a GPA; 80OEO, which included 80 ppm OEO and no GPA; and 150OEO, which included 150 ppm OEO and no GPA. Results: All of the OEO and GPA treatment groups had a better feed conversion ratio than the NC group. However, the addition of 150 ppm OEO to the diet improved the percentage egg production and egg mass, as well as the external and internal quality of the egg compared with the other treatments. In addition, both the 80OEO and 150OEO treatments improved the yolk color, shell thickness, and shell color, as well as parameters related to the intestinal morphometry compared with the NC group. Conclusion: The findings of this study indicate that 150 ppm OEO can be used as a substitute for GPA to improve the performance, egg quality, and parameters related to the intestinal morphometry of ISA Brown laying hens.

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

Treatment Groups

One hundred and eighty 7-week-old laying quail were fed various diets over a 12-week period. The diets included a control diet (without essential oil mixture (EOM) or antibiotics (ANTs)), a basal diet including EOM (24 mg/kg feed), and a basal diet including an ANT (avilamycin, 10 mg/kg feed). Each treatment comprised 4 replications with 4 cages (15 quail per cage), amounting to 60 quail per treatment group. Diets (in mash form) and water were provided forad libitumconsumption. EOM consisted of 6 different essential oils derived from the following herbs: oregano (Origanumsp.), laurel leaf (Laurus nobilisL.), sage leaf (Salvia trilobaL.), myrtle leaf (Myrtus communis), fennel seeds (Foeniculum vulgare), and citrus peel (Citrussp.). In comparison with the control diet, adding supplements such as EOM and ANTs to the basal diet increased egg production in quail (P<0.001). However, egg production was similar between EOM and ANT treatment groups. Moreover, there were no differences between the treatment groups with regard to egg weight. Feed intake was not affected by EOM or ANT supplementation, whereas feed conversion ratio was significantly improved by EOM and ANT supplementation. Thus, we concluded that EOM has beneficial effects as a dietary supplement on egg production and feed conversion ratio.

Main Effects

The effects of peeling and limestone flour level on the utilisation of Alocasia macrorrhiza corm meal (ACM) by laying hens were investigated. Maize-based diets with two concentrations of limestone flour (40 and 60 g/kg) and diets containing 200 g peeled and unpeeled ACM meal/kg with the same levels of limestone flour were fed to five replicate pens containing 10 20-week-old Shaver brown pullets (1635 ± 148 g), each for 105 days. Results showed no interaction or main effects of ACM or limestone concentration on feed intake, egg weight, egg mass, feed conversion efficiency, egg shape index, surface area and Haugh unit (P &gt; 0.05). Feeding whole ACM with 40 g limestone/kg diet reduced hen-day production and shell thickness (P &lt; 0.05) but this was overcome by increasing limestone concentration to 60 g/kg diet. Peeled ACM with both concentrations of limestone flour maintained laying performance and egg quality. We concluded that feeding 200 g whole ACM depresses egg production and shell quality in laying hens, but increasing dietary limestone concentration overcomes this adverse effect. The concentration of limestone flour in the diet has no effect on laying performance. Higher inclusion levels of ACM, calcium source and level that will maintain laying performance and reduce feed cost need to be investigated.

Context Organic and herbal additives in feed may lead to more healthy animal products. For this study, we hypothesised that an organic form of selenium and/or a herbal additive (oregano, Origanum vulgare L.) may improve performance of laying hens. Aims The study was designed to determine the effects of selenium source (SS, sodium selenite; or selenium yeast, SY), oregano essential oil (OEO) and a combination of Se and OEO on performance, egg quality and blood parameters of laying hens. Methods In total, 216 Lohmann LSL-Lite laying hens, 66 weeks of age, were assigned to feed on one of six diets: control group, receiving basal diet (BD); BD + 0.3 mg SS/kg; BD + 0.3 mg SY/kg; BD + 250 mg OEO/kg; BD + 250 mg OEO + 0.3 mg SS/kg; BD + 250 mg OEO + 0.3 mg SY/kg. For each treatment, there were six replicates of six hens each for 12 weeks. Key results Feed conversion ratio was higher (P &lt; 0.05) with the OEO diet than in the control. The SY diet decreased egg production and the OEO diet decreased egg mass (P &lt; 0.05), although this effect was reversed with the SY + OEO diet. This would illustrate a synergistic effect of OEO with SY. Highest and lowest yolk colour values were found with the SY and SS diets, respectively (P &lt; 0.05). Serum uric acid was lower with diets containing Se than the control diet (P &lt; 0.05). Glutathione peroxidase activity was highest with SY and SY + OEO diets and lowest with the OEO diet (P &lt; 0.05). Birds fed the SS + OEO diet showed the highest total antioxidant capacity and those fed SY showed the lowest total antioxidant capacity (P &lt; 0.05). Conclusions Based on the results of the current study, it can be concluded that SY diet have increasing effect on egg weight in laying hens. In addition, novel synergistic effects between OEO and SY diets on improving egg production, egg mass and feed conversion ratio have been found. In terms of oxidative status, the detected synergistic effects between OEO and SS diets on total antioxidant capacity and between OEO and SY diets on glutathione peroxidase (GPx) have not been reported before, that appreciate more clarifying investigations in future. Although, dietary supplemental SY individually and also with OEO increased GPx, adding SS to diet together with OEO showed more improving effect on GPx compared to the separate usage. Implications Dietary supplemental SY can improve egg weight in laying hens. In addition, adding SY to diet of laying hens individually and with OEO have beneficial effects on oxidative status of bird in terms of GPs activity, which in turn can ameliorate the unfavourable impressions of probable environmentally oxidative stress on productive performance.

A study was conducted in order to estimate the sodium requirements of Japanese laying quail (Coturnix coturnix japonica). In this study, we used 280 Japanese quails at 128 days of age, with an average weight of 9 ± 5.2 g, and an egg production rate of 82.3 ± 0.94%. An experimental design methodology was employed, completely randomized with five treatments and seven replications. Each replicate consisted of eight quails, with a total of thirty-five experimental units. The experimental diets were based on corn and soybean meal, and contained five different levels of sodium (0.08%, 0.12%, 0.16%, 0.20% and 0.24%). The diets were isocaloric and contained equal concentrations of amino acids, with an electrolyte balance of 250 mEq/kg. The parameters we evaluated were feed intake (g/quail/day); egg production per quail per day (%); egg weight (g); egg mass (g/quail/day); and feed conversion by egg mass (kg/kg) and per dozen eggs (kg/dz). In addition, we evaluated the composition of the eggs in terms of the absolute (g) and relative (%) mass of the yolk, albumen and eggshell. We also measured the body weight variation (g) and viability (%) of the quails. There were no significant effects (p>0.05) on the described parameters. No nutritional disorders occurred related to the level of inclusion of sodium in the diets. The inclusion of 0.08% sodium in the diet of laying Japanese quails was satisfactory to maintain egg production and quality without losses in feed intake or feed conversion.
