Rasyona Kakule Tozu İlavesinin Yumurtlayan Bıldırcınlarda Performans, Yumurta Kalitesi ve Serum Biyokimyasal Parametrelerine Etkisi

The present research was carried out to determine the effects of the addition of cardamom powder at different levels (0, 1, 2, 3 or 4 g/kg) to diet on performance, egg quality, and serum parameters in laying quails. In the experiment, a total of 120 laying quails at the age of 20 weeks were randomly distributed to 5 treatment groups with 6 subgroups (4 quails each). Quails were fed with experimental diets for 10 weeks. In the experiment, the feed intake of quails significantly increased with the supplementation of cardamom powder at the level of 3 g/kg to the diet, while other performance parameters were not affected. Eggshell thickness advanced with the addition of 1 g/kg cardamom powder to diet. Egg yolk L* value increased at the level of 4 g/kg, but a* value decreased with the addition of cardamom powder. Other egg quality parameters were not affected by the addition of cardamom powder to the diet. In addition, the supplementation of cardamom powder to the diet significantly reduced serum cholesterol levels of quails. According to the results obtained from the experiment, the addition of cardamom powder at the level of 3 g/kg to the diet increased the feed intake of quails, while the supplementation of 1 g/kg was effective in improving the eggshell quality and serum cholesterol level.

Phosphorus Levels

The effects of diet type (wheat- or maize-based) and concentration of available phosphorus (AP; about 4, 3 and 2 g/kg) on the parameters of hen performance and egg quality as well as shell calcium (Ca) and phosphorus (P) contents were examined. Two experiments were carried out in which 240 and 120, respectively, older ISA Brown hens were housed in enriched cages. The interaction of diet type and AP concentration was ascertained for all evaluated characteristics except the amount of Ca and P deposited in shells in the first experiment. In the second experiment, the interaction of diet type and AP concentration was found for feed intake, egg weight, shell thickness and weight as well as the albumen quality parameters. Furthermore, Ca deposition in shells increased (P < 0.001) with the wheat diet. Hens fed a maize-based diet (P < 0.001) laid heavier eggs. The highest level of AP (4.1 g/kg) in the wheat-based diet significantly (P < 0.001) decreased albumen height, albumen index and Haugh units (HU). These trends were the same in both experiments. The results indicate that 0.27% AP in wheat-based diet and 0.30% AP in maize-based diet are adequate for hens with the intake 115 g of feed with 3.5% of Ca without a negative impact on performance or egg quality.

Rosemary Essential Oil

This experiment was designed to investigate the effects of rosemary essential oils in various doses on hen performance, egg quality, lipid peroxidation malondialdehyde (MDA) level in fresh and stored egg yolk. The experiment was carried out in random parcel experimental design. In the experiment, 6 groups were formed and each group was divided into 5 replicates. In total 240 Bovans hite laying hens, each replicate included 8 hens, 32 weeks old, were used. Treatment groups were control (Negative Control), 500 mg//kg antibiotic (Positive Control 1), 200 mg/kg vitamin E (Positive Control 2), 100 mg/kg rosemary essential oil, 200 mg/kg rosemary essential oil, 300 mg/kg rosemary essential oil. There was no significant difference in live weight, egg production, egg weight, damaged egg ratio, mortality and egg quality but feed comsumption, feed conversion ratio (FCR) and egg yolk MDA values were affected significantly in between control and treatment groups. At all treatment groups feed comsumption decreased significantly and other groups improved in feed conversion ratio except 500 mg/kg antibiotic and 100 mg/kg rosemary doses groups compared to negative control significantly. 100 mg/kg rosemary essential oil addition during the storage time for 42 and 56 days and 200 mg/kg vitamin E addition for all storage time to ration decreased egg yolk MDA values significantly. As a result, laying birds fed 200 mg/kg vitamin E, and 100 mg/kg of rosemary essential oil additives can use to prevent lipid oxidation.

Shell Quality

The comparison of physical quality properties of table eggs of commercial hybrid Tetra SL and two native indigenous breeds of hens, Banat Naked Neck and Svrljig hen, was performed in conditions of alternative production in the pasture system in portable cages without the floor. The experiment was conducted during the vegetation period, at the age of hens of 53-57 weeks. In order to produce good quality eggs, the diet was designed with a complete mixture based on maize and soybean. In addition, constant availability of pastures was ensured. Egg sampling was performed in the morning and the initial egg quality was examined based on egg weight, shape index, egg white, egg yolk and shell quality parameters. Layer hens of the commercial hybrid Tetra SL had significantly higher egg weight and better internal egg quality (p<0.01) compared to hens of Banat Naked Neck and Svrljig hens, except for the colour of the yolk, which was more intense in the same feeding and breeding conditions and the age of laying hens, in eggs of native breeds (p<0.01). Native breeds in relation to the commercial hybrid had lighter shell colour (p<0.01). Deformation and egg shell thickness differed (p<0.01) between all three genotypes. The determined rank of layer hen genotypes for shell thickness was: Tetra SL, Banat Naked Neck, Svrljig hen. However, the breaking force was without statistically confirmed difference between hen genotypes.

The aim of this study was to investigate the effects of different levels of alfalfa meal on performance, egg quality, egg yolk cholesterol and hatchability parameters of quail breeders. In this trial a total of 90 Japanese quail breeders (30 males, 60 females), 10 weeks old was distributed 5 experimental groups randomly. Each experimental group consisted of 6 replicates of 3 quails (1 males, 2 females) in each. During the 12 weeks experiment period, birds were fed with 5 dietary groups based on corn and soybean meal and containing 0 (control), 10, 20, 40 and 80 g/kg alfalfa meal. Feed and water were offered ad-libitum throughout the experiment. The different dietary levels of alfalfa meal had no significant effect on body weight change, egg production, egg weight, egg mass, feed conversion ratio, egg shell breaking strength, egg yolk triglyceride, fertility, hatchability of fertile eggs or hatchability of eggs set. The feed intake was decreased with 10 or 20 g/kg alfalfa meal levels in the diet. The eggshell weight was best in quails fed 20 g/kg alfalfa meal, and the egg yolk cholesterol was the lowest in quails fed 40 g/kg alfalfa meal. According to the results of this study the addition of 40 g/kg alfalfa meal in laying quail diets decreased the egg yolk cholesterol levels without adverse effect on performance.

1. The effect of biotin supplementation of low-biotin practical diets during rearing and laying stages on performance was studied in White Leghorn-type laying hens.2. Biotin supplementation during rearing did not have any apparent effect on the condition of the bird at point-of-lay or on subsequent laying performance.3. Biotin supplementation during lay did not have any beneficial effect upon egg number, egg size or food intake or food conversion efficiency.4. Internal egg quality, as reflected by albumen height, was slightly improved by biotin supplementation of layer's diet.5. Input-output relationships were calculated for the incorporation of biotin in egg yolk.6. Metabolic measurements suggested that biotin concentration in egg yolk was the best criterion of biotin status in the hen.7. It is concluded that practical diets contain sufficient biotin to support optimum egg-laying performance in hens.

Vitamin K3 ◽

Liquid Chromatography Tandem Mass

National nutrition surveys have shown that over half of all adults in Ireland, the United Kingdom (UK), and the United States of America (USA) have low vitamin K intakes. Thus, dietary strategies to improve vitamin K intakes are needed, and vitamin K biofortification of food may be one food-based approach. The primary aim of our study was to establish whether increasing the vitamin K3 content of hen feed can increase the vitamin K content of eggs, and the secondary aims were to examine the effects on hen performance parameters, as well as egg and eggshell quality parameters. A 12 week hen feeding trial was conducted in which Hyline chickens were randomized into four treatment groups (n = 32/group) and fed diets containing vitamin K3 (as menadione nicotinamide bisulfite) at 3 (control), 12.9, 23.7, and 45.7 mg/kg feed. Vitamin K1, menaquinone (MK)-4, MK-7, and MK-9 were measured in raw whole eggs via a liquid chromatography tandem mass spectrometry method. MK-4 was the most abundant form of vitamin K (91–98%) found in all eggs. Increasing the vitamin K3 content of hen feed over the control level significantly (p < 0.001) enhanced the MK-4 content of eggs (mean range: 46–51 µg/100 g, representing ~42–56% of US Adequate Intake values). Vitamin K biofortification also led to significant (p < 0.05) increases in the yellowness of egg yolk and in eggshell weight and thickness, but no other changes in egg quality or hen performance parameters. In conclusion, high-quality vitamin K-biofortified eggs can be produced with at least double the total vitamin K content compared to that in commercially available eggs.
