ABSTRACT. Penelitian bertujuan untuk mengetahui pengaruh penambahan pakan ampas kelapa (AK) yang difermentasi dengan penambahan ammonium sulfat (AS) terhadap produksi dan kualitas telur telah dilaksanakan. Ampas kelapa ditambahkan AS dengan konsentrasi 0, dan 4% dan 0.1% Ragi (Fermipan®) dan diinkubasi selama 5 dan 7 hari. Substrat yang dihasilkan dicampur kedalam pakan dan diberikan kepada 75 ekor ayam petelur fase bertelur umur 20 minggu selama 24 minggu. Pakan perlakuan yang diberikan adalah: pakan kontrol (KTL), kontrol + AK tanpa AS yang difermentasi selama 5 hari (F5-0AS), kontrol + AK dengan 4% AS yang difermentasi selama 5 hari (F5-4AS), kontrol + AK tanpa AS yang difermentasi selama 7 hari (F7-0AS) dan kontrol + AK dengan 4% AS yang difermentasi selama 7 hari (F7-4AS). Penelitian ini menggunakan rancangan acak lengkap dengan 5 perlakuan, 5 ulangan dan 3 ekor ayam per ulangan. Data yang diperoleh dianalisis dengan analisis ragam dan dilanjutkan dengan uji Tukey. Hasil penelitian menunjukkan bahwa konsumsi ransum, produksi telur, bahan kering ekskreta dan kualitas telur dipengaruhi oleh pakan perlakuan (P0,05). Perlakuan tidak memberikan pengaruh yang nyata (P0,05) terhadap bobot telur, kecernaan bahan kering, persentase kerabang telur, indeks telur dan tinggi albumen. Total bobot telur tertinggi diperoleh pada ayam yang diberi perlakuan fermentasi baik tanpa ataupun dengan penambahan AS. Fermentasi selama 7 hari dapat meningkatkan produksi henday dan jumlah telur. Kualitas terbaik dari aspek indeks kuning telur dan Haugh unit adalah pada perlakuan F7-4AS. Penelitian dapat disimpulkan bahwa fermentasi dapat meningkatkan total bobot telur dan AS dapat meningkatkan kualitas telur dalam bentuk Haugh unit.  (The effect of coconut dregs fermented with the addition of ammonium sulfate on production and quality of eggs) ABSTRAK. An experiment was done to determine the effect of coconut dregs (CD) with the addition of ammonium sulfate (AS) prior to fermentation on productive performance and egg quality. Coconut dregs were added with 0 and 4% AS and 0.1% yeast S. cerevisiae (Fermipan®) after autoclaving. The substrates were incubated for 5 and 7 days and mixed into diets and offered to 75 laying hens for 24 weeks. The experimental diets were: control diet (KTL), basal + 5-days- fermented coconut dregs (FCD) without AS (F5-0AS), basal + 5-days FCD with 4% AS (F5-4AS), basal + 7-days- FCD without AS (F7-0AS), basal + 7-days-FCD with 4% AS (F7-4AS). Data were analyzed using analysis of variance with 5 treatments and 5 replications. Data were further tested by the Tukey test. Results of the study indicate that feed intake, hen day production, total egg, total egg mass, excreta dry matter, yolk height, yolk index, and the Haugh unit were statistically affected by the treatments (P0.05). The effects of treatments were not statistically significant (P0.05) on individual egg mass, dry matter digestibility, eggshell percentage, egg shape index, and albumen height. The highest total egg mass was found in birds fed the FCD diets. Fermentation for 7 days could improve hen day production total egg. The higher yolk index and Haugh unit were produced by the hens fed the F7-4AS diet than those eggs produced by controlled laying hens. In conclusion, fermentation could improve total egg mass and AS supplementation could increase the Haugh unit.

Abstract This research aims to study and analyze the effect of adding turmeric flour (Curcuma domestica Val) in the rations on the performance of 70 weeks old Isa Brown strain of laying hens. The research method used in this study was an experimental method with a completely randomized design (CRD) step with five treatments and four replications. The number of chickens used was as many as 40 laying hens. The treatments given to the sample were P0 = feed without giving turmeric flour (control), P1 = feed with 0.3% turmeric flour, P2 = feed with 0.5% turmeric flour, P3 = feed with 0.7% turmeric flour and treatment P4 = feed by giving turmeric flour 0,9%. The results showed that giving turmeric flour in the rations of the Isa Brown strain of laying hens affected chicken performance and egg quality. This research concludes that giving turmeric flour a percentage of 0.7% in Isa Brown’s 70-week old laying hens is the best for ration consumption, Hen Day Production, egg weight, feed conversion, and egg quality: Haught Unit, yolk egg color, yolk egg index, grading egg and egg mass. Based on the haugh unit value, all eggs produced are still in the AA grade category

SUMMARY This study was performed to evaluate the effect of the inclusion of paprika and marigold extracts in sorghum-based rations on the productivity and egg quality of laying hens. One hundred sixty laying hens were distributed in a completely randomized design in five treatments and in a factorial arrangement (2 × 2 + 1), one control ration based on corn, two levels of paprika extract (0 and 6 g/kg diet), and two levels of marigold extract (0 and 1 g/kg diet) in sorghum-based rations. There was no effect (P > 0.05) of the treatments on the weight, specific weight, and Haugh unit of the eggs and productive performance, but the inclusion of paprika extract resulted in eggs with lower egg pH. The interaction between the control group and the factorial was significant (P < 0.05) to the laying rate, egg mass, and yolk color, whose values were lower with sorghum-based diets with no pigment compared to control treatment. The interaction between the paprika and marigold extracts was significant increasing the height (P < 0.03) and color (P < 0.0001) of the yolk when paprika extract was used, with or without marigold extract. Marigold extract inclusion reduced the percentage (P < 0.02) and thickness (P < 0.01) of the eggshell. As conclusion, the inclusion of paprika extract in sorghum-based diets for laying hens is viable for improving the egg quality.

The present study determined, assessed and quantified the exogenous phytase on egg production and egg quality of spent hens. Ninety laying hens (ISA- Brown) received iso-energetic and iso-nitrogenous diet supplemented with 0, 0.05, 0.1, 0.15 and 0.2 % phytase and reared in cages. Each layer was fed 120g feed/day from 90 to 100 weeks of age. At the inception of the study the spent hen at the age of 90 weeks had an average egg production 65.21 %. Phytase addition in diet increased (p<0.05) egg production  (7.67, 12.17, 12.04 and 15.87 % higher than control group), egg mass output (5.5, 9.34, 7.65 and 12.72 % higher than that of control) and feed conversion, but it did not alter shell weight, shell thickness, shape index, albumen index, Haugh unit, per cent yolk and yolk color. It was concluded that reduced egg production of spent hen at older ages to some extent might have a relationship to decreased availability of phosphorus. The decreased egg production in hens at older ages could be corrected by adding appropriate phytase level in the diet. Thus, it may be possible to extend and prolonged productive life of spent hens by supplying exogenous phytase in diet. However, the effect of availability of phosphorus on egg production using larger population for a longer period may be performed to confirm the findings of the current study.

The present study aimed to evaluate the effect of two dietary Ca levels (3.00% vs 3.50%) in three hen genotypes (ISA Brown, Bovans Brown and Moravia BSL) on their laying performance and quality of their eggs. In order to evaluate the response to dietary Ca, an experiment was conducted with 300 laying hens. One hundred birds from each genotype were divided into 10 replicates (10 birds/cage/Ca level). To reveal the differences, the following characteristics were measured: hen-day egg production percentage, daily feed intake, egg weight, albumen and yolk weights, Haugh unit, eggshell colour, eggshell weight, eggshell thickness, eggshell strength, egg shape index and eggshell index. A higher Ca level significantly increased the hen-day egg production percentage of Bovans Brown and Moravia BSL, while ISA Brown laying hens had the higher egg production percentage at a lower dietary Ca level (85.97% vs 82.41%). No significant effect of dietary Ca level was observed on any internal egg quality measurements except the Haugh unit. However, the dietary Ca level significantly affected some of external egg quality measurements, namely eggshell colour (P &lt; 0.001), eggshell weight (P = 0.003) and eggshell strength (P = 0.012). The results of the present study show that laying performance and egg quality parameters responded differently according to hen genotype and dietary Ca level. Bovans Brown and Moravia BSL laying hens required higher levels of Ca to keep egg production high, while the eggshell quality measurements were better at the lower dietary Ca level. Thus, it is recommended to adjust the Ca levels in feed to the nutritional requirements of laying hens.

Effect Of Age

The aim was to assess the internal and external quality of consumer eggs of egg‑laying hens of two selected genotypes depending on their age. All of these hens were kept in enriched cages. There were compared eggs from Hy‑Line Brown and ISA Brown hens at the age from 36 to 64 weeks. In total, 3840 eggs from 300 hens were evaluated. Quality of eggs was determined by their technological value. Statistically significant interactions (P = 0.001) between age and genotype were found in all evaluated parameters except for the yolk colour (P = 0.044), whereas there was not found interaction (P = 0.072) between age and genotype in eggshell strength. The significant effect of hens’ age was found in all evaluated parameters, with the only exception of the yolk colour. The results showed that the average weight of eggs, eggshell, albumen and yolk increased with the age. Also the eggshell proportion, its colour and yolk index values ​​increased, whereas the egg shape index, eggshell thickness and strength, albumen proportion, Haugh units, the albumen and the yolk index decreased. Statistically significant effect of the genotype was found in all evaluated parameters except for the yolk index. When comparing both genotypes, the eggs from ISA Brown hens had a better quality. The trend of deteriorating egg quality with age was confirmed.

In this study, the effects of coat difference and breeding age on the internal and external quality of the eggs were investigated in white laying hens in different cages. The eggs obtained from a total of one hundred fifty eggs White layer pure line hens at 24, 28, 32, 36 and 40 weeks of age that housing in individual cages in the Ankara Poultry Research Institute were used. Shape Index, egg weight (g), albumen height (mm), Roche scale, Haugh unit and shell strength (N) values were examined in 438 eggs obtained from these chickens found in these cages which are three tiers as upper, middle and bottom. In addition, temperature and humidity values in the tiers were recorded at 30-minute intervals during the study and then they were analysed. Statistically significant differences were calculated between temperature and humidity values measured in tiers. Although there was no difference between the tiers in terms of shape index and egg weight, the effect of age was significant. The effect of age and tiers difference on albumen height (mm) was insignificant. The Roche scale and shell strength (N) values were significantly influenced by the tier difference and breeding age. In general, it was concluded that the effect of the tier difference on the Haugh unit was insignificant, but the age was found to have an effect on the Haugh unit.

This study was conducted to appraise the effects on egg quality and production performance of laying hens when drinking water was supplemented with calcium (Ca) and magnesium (Mg). A total of 384 (64-week-old) Hy-line Brown laying hens were assigned at random to four treatments, which consisted of CON: unsupplemented drinking water; T1: drinking water + 2 mg/L Ca + 250 mg/L Mg; T2: drinking water + 4 mg/L Ca + 510 mg/L Mg /10 L; and T3: drinking water + 5 mg/L Ca and 760 mg/L Mg. The experiment lasted six weeks. Water intake increased linearly in week 1 with the rising levels of Ca and Mg in the drinking water. Increasing the Ca and Mg levels improved eggshell strength (week 2 (P =0.01), week 5 (P =0.01), and week 6 (P = 0.03), and eggshell thickness (week 6) (P =0.02) and reduced the rate at which eggs were broken (week 4) (P =0.01). The supplemental Ca and Mg did not affect egg production, egg weight, Haugh unit, albumen height, eggshell colour, and yolk colour compared with CON. Nor did they influence the Haugh unit and albumen height after storing for 1, 5, 10 and 15 days. In conclusion, adding Ca and Mg to the drinking water increased the thickness and strength of the eggshells.

Abstract:The objective of this work was to evaluate the effect of limestone particle sizes in the diet and of lighting regimes on the egg and bone quality and on the performance of commercial laying hens. Three hundred Hissex White layers, at 18 weeks of age, were distributed in a completely randomized design, in a 5×2 factorial arrangement (coarse limestone in the diet at 0, 25, 50, 75, and 100%; with or without artificial light), with five replicates of six birds. No significant interaction was observed between particle sizes and lighting regime for the evaluated parameters. There was no significant effect of coarse limestone level in the diet on the performance and egg quality of hens; however, bone deformity (3.23 to 4.01 mm), strength (5.19 to 6.70 kgf cm-2), and mineral matter (51.09 to 59.61%) improved as the proportion of coarse limestone increased. For lighting regime, the treatment with artificial light yielded higher Haugh unit values (87.17 vs. 85.54) than that with natural light only. Greater limestone particles improve bone quality of laying hens, and the use of artificial light can benefit the albumen quality of the eggs.

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.

The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was carried out. The following metrics were evaluated: egg weight, yolk weight, shell weight; yolk color, albumen height, specific gravity, and Haugh unit as well as the yolk, shell, and albumen percentage relative to the total weight of the egg. There was no significant interaction between additives and storage time (p > 0.05) for most of the parameters evaluated. The only exception was observed for yolk color, in which the interaction effect between treatments was significant (p < 0.05). The effect of storage time was significant (p < 0.05) for albumen weight, albumen percentage, yolk color, albumen height, specific gravity, and Haugh unit, with reduction of these parameters over the evaluation period. The use of paprika and marigold flower extract in the diets of Black Avifran laying hens does not influence egg quality.
