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 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.

Sorghum is the primary alternative feedstuff for corn in some developed countries in the production of poultry. Thus, four hundred and fifty 32 weeks old Lohmann Brown laying hens were used in a study to evaluate the effect of replacing maize with sorghum with or without enzymes supplementation, on egg laying performance and egg quality characteristics of laying hens. Birds were distributed randomly into six dietary treatments with three replicates per treatment, each replicate had 25 birds with uniform initial group weights. The treatments included maize without enzymes (T1); sorghum without enzymes (T2); as controls respectively, while T3, T4, T5, and T6 contained sorghum based diets with phytase, protease, G2G, and a combination of protease and G2G respectively. Laying performance, cost of production, and egg quality characteristics were determined for the period of the trial, 33-56 weeks of age of the birds. All data obtained were subjected to analysis of variance, using the completely randomized design (CRD) and significant differences among treatment means were compared using the Tukey test. Significant (p<0.05) differences were observed among dietary treatments but with no defined trend observed for egg production traits. Daily feed intake was significantly (p<0.05) higher in maize control diet compared to the other treatments. Diets supplemented with phytase (T3), protease (14), and combination of protease and roxazyme G2G (T6) had significantly (p<0.05) better feed conversion ratio with T3 having the lowest value of 4.01 compared to the other treatments. For feed cost/dozen egg (N), Kg feed/dozen eggs, income above feed cost at N30 per egg, and income above control treatment; phytase (T3), protease (T4), roxazyme 626 (T5), and protease + roxacyme G2G (T6) diets in this study showed better performance than the control. Sorghum diet without enzyme had significantly (p<0.05) least performance for egg number. Hen housed egg production (HHP) and hen day egg production (HDP) compared to the other treatments while sorghum diet with phytase had the highest value (60.12g/day) for average egg weight compared to the other treatments. Egg quality characteristics showed the best performance for dietary treatments supplemented with phytase (T3) in all the other parameters considered, apart from the albumen height, yolk diameter, and yolk index. It was concluded therefore, that sorghum with phytase and protease supplementations can be used in layers' diets as a substitute for maize for optimum egg production.

The study was conducted to investigate the external and internal egg quality characteristics of two local strains of turkey during their early reproductive age. A total of 96 freshly laid eggs were sampled from two local turkey strains having black and white plumages. The turkeys were 33weeks of age with two months into lay. Data were collected weekly for three weeks on egg weight, egg length, egg diameter, shell thickness, shell weight, shell index, albumen weight, yolk weight, albumen: yolk ratio, albumen length, yolk length, albumen diameter, yolk diameter, albumen height, yolk height, yolk index and Haugh unit and analyzed using the statistical package of SAS. The results revealed that highly significant (p<0.01) differences in the external traits occurred in egg weight, egg length and shell weight with the white turkey strain been superior. Also, the internal traits recorded highly significant (p<0.01) differences in albumen weight, yolk weight, albumen: yolk ratio, albumen length, yolk length and yolk diameter with the white strain performing better than the black strain. Highly significant correlations (p>0.01) exits in most of the correlated traits with the except for Haugh unit that had no significantly (p<0.01) correlations. Thus, since significant variations exits between the two strains, selection activities are recommended to improve these economic traits in egg weight using it has an index in selection and in possible prediction of the quality of poults to be hatched. Also, economically, it may be used to know the consumers' preference on the quality of turkey eggs consumed.     L'étude a été menée pour étudier les caractéristiques de qualité externe et interne des œufs de deux souches locales de dinde au début de leur âge de reproduction. Un total de 96 œufs fraîchement pondus ont été échantillonnés à partir de deux souches de dinde locales présentant des plumages noirs et blancs. Les dindes étaient âgées de 33 semaines avec deux mois de ponte. Des données ont été collectées chaque semaine pendant trois semaines sur le poids de l'œuf, la longueur de l'œuf, le diamètre de l'œuf, l'épaisseur de la coquille, le poids de la coquille, l'indice de la coquille, le poids de l'albumine, le poids du jaune, le rapport albumine: jaune, la longueur de l'albumen, la longueur du jaune, le diamètre de l'albumen, le diamètre du jaune, l'albumine hauteur, hauteur du jaune, indice de jaune et unité Haugh et analysés à l'aide du progiciel statistique de 'SAS'. Les résultats ont révélé que des différences très significatives (p = 0,01) dans les caractères externes se produisaient dans le poids des œufs, la longueur des œufs et le poids de la coquille avec la souche de dinde blanche supérieure. En outre, les traits internes ont enregistré des différences très significatives (p = 0,01) dans le poids de l'albumine, le poids du jaune, le rapport albumine : jaune, la longueur de l'albumine, la longueur du jaune et le diamètre du jaune, la souche blanche fonctionnant mieux que la souche noire. Des corrélations hautement significatives (p?0,01) existent dans la plupart des traits corrélés avec l'unité à l'exception de Haugh qui n'avait pas de corrélations significatives (p?0,01). Ainsi, étant donné que des variations importantes existent entre les deux souches, des activités de sélection sont recommandées pour améliorer ces caractères économiques en poids de l'œuf en utilisant un indice de sélection et de prédiction éventuelle de la qualité des dindonneaux à éclore. Aussi, économiquement, il peut être utilisé pour connaître la préférence des consommateurs sur la qualité des œufs de dinde consommés.

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 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

The aim of this study was to test the use of carrot juice fermentation with probiotics in rations with different levels on the production performance and quality of egg-laying hens. The material used was Lohman Brown strain of laying hens, 27 weeks old with an average initial body weight of 1.69 kg, as many as 45 birds. The research was conducted with experimental methods and used a Complete Design Acal (CRD). The treatment tested was the use of Carrot Extract Fermentation (FLSW) with probiotic SOC in the feed consisting of T1 = 100% basal ration, T2 = basal ration (97.5%) + FLSW (2.5%): T3 = basal ration ( 95%) + FLSW (5%); T4 = basal ration (92.5%) + FLSW (7.5%); T5 = basal ration (90%) + FLSW (10%). The variables observed were production performance (consumption, egg production (HDA / Hen Day Average), egg weight, egg mass, feed conversion and income over feed cost) and egg quality variables (albumin index, yolk index, Haugh Unit (HU), yolk color, albumin pH, yolk pH). The results of the analysis of variance showed that the use of carrot extract fermentation (FLSW) with different levels had a significant effect on feed consumption (Sig.115) and HDA (Sig.063), yolk index value (Sig.087) and yolk color (Sig. 000). , and not significantly different on feed conversion (Sig. 403), albumin index value (Sig. 522), and Haugh Unit (Sig. 259). The conclusion of the research showed that the use of fermented carrot juice waste (FLSW) in the feed of laying hens had an effect on feed consumption, egg production (Hen Day Averag / HDA), yolk index and yolk brightness (yolk color), but had no effect on conversion. feed, Haugh unit and albumin index value. Key words : probiotics, fermentation, carrot juice waste, production performance, egg quality
