ABSTRACT: It was possible to evaluate the effect of continuous and intermittent lighting programs with different photophases on the performance and eggs quality of laying hens, applied to the beginning of the laying phase. The authors used 420 Hy-line Brown laying hens with 21 weeks of age, bred on bedding and submitted for six periods of 28 days between the solstice of summer and winter. The three lighting programs were: (PIC) 16 hours of continuos light, intermittent program with initial and final photophases of 15 minutes (PII15) and an intermittent program with initial and final photophases of 30 minutes (PII30). A completely randomized design with ten repetitions of 14 birds was used. The mean values were subjected analysis of variance and analyzed by the Tukey test (5%). The PIC program showed higher feed intake and eggs' mass about the PII15, and the eggs production of birds, in the PIC, was 1.8% greater than the intermittent photoperiods. Programs of light did not change the egg quality. The intermittent programs for semi-heavy laying hens bred on bedding in an open shed, applied at the beginning of the laying phase, reduced the productive performance of the birds without affecting the eggs quality.

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

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.

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 main objective of this research is to evaluate the inclusion of different natural pigment solutions in diets formulated with maize and sorghum solutions on the growth performance and egg quality of commercial laying hens created in hot climates. Throughout the conduction of this experiment, were used 252 laying hens of the Hisex Brow, in a completely randomized design, with six treatments, seven repetitions, and six birds per plot. The experimental diets were assigned with different energy sources and adding pigmentation solutions, diet 1 (corn), diet 2 (corn + annatto), diet 3 (corn + carrot), diet 4 (sorghum), diet 5 (sorghum + annatto), diet 6 (sorghum + Carrot).  Afterward, being evaluated the performance and quality of eggs. It was observed significant difference with reference t egg production, egg weight (g), gem weight (g), the weight of shell (g), albumin in weight (g), and gem coloration (tons) among the treatments. There was no difference in the parameters of performance and quality of eggs evaluated, only the variable yolk color had a significant effect between treatments. Replacing the energy source of the corn diet with sorghum in the diet of laying hens at peak production provides similar performance and egg quality, which can be a substitute for quality and efficiency. The use of annatto and carrots as a natural pigmentation promotes greater pigmentation of the egg yolks of laying Hisex Brown eggs and does not impair the performance of the birds.

Non-conventional feeds are generally of low quality so feed fermentation needs to be done to increase its use. This research was conducted to examine the effect of giving fermented feed types on egg quality. This research was conducted in June until August 2018 in the cage of Cibadak poultry in Sukabumi district. The animals used in this study were 24 Brown Strain Isa Brown laying hens as many as 24 birds. The study used a completely randomized design (CRD) consisting of 6 treatments and 4 replications. The treatment in this study was R0 = 100% Basic Ration, R1 = 90% Basic ration + 10% fermented non conventional ration, R2 = 80% Basic ration + 20% fermented non conventional ration, R3 = 70% Basic ration + 30% Non ration conventional fermented, R4 = 60% Basic ration + 40% Fermented non-conventional ration, R5 = 50% Basic ration + 50% Fermented non-conventional ration. The data obtained were analyzed using Analysis of variance (ANOVA), if the data showed results that were significantly different (P <0.05) followed by the Duncan test. The results showed that substitution feeding did not significantly influence the egg index, egg white weight, Haugh Unit value, and shell thickness. Therefore, it can be concluded that demonstrable non-conventional feed can be given in ration of laying hens up to 50%.

The objective of the experiment was to evaluate effects of dietary supplementation of β-mannanase (Hemicell®) on productive performance, egg quality, and fecal moisture content in laying hens from 20 to 35 weeks of age. A total of 375 Isa Brown’s hens (1615.6 ± 76.4 g/bird) were randomly assigned to 5 treatments in a completely randomized design. The 5 dietary treatments included (1) basal diet with a level of 2800 kcal ME and no β-mannanase supplementation (HE, Control), (2) HE + 32 units of β-mannanase/g of feed, (3) HE + 64 units of β-mannanase/g of feed, (4) basal diet with a level of 2700 kcal ME (LE) + 32 units of β-mannanase/g of feed, and (5) LE + 64 units of β-mannanase/g of feed. Each treatment was replicated with 25 cages of 3 hens each. All diets were in meal form and contained no antibiotics. The addition of β-mannanase to HE diets did not affect the egg production of birds as compared with the control (P > 0.05). The birds fed LE diets with β-mannanase had the same egg production as those fed the control and β-mannanase-supplemented HE diets (P > 0.05). Differences in egg weight, egg quality, survival rate, and fecal moisture content were not significant among the treatments (P > 0.05). Briefly, addition of β-mannanase (32 units/g of feed) to LE diets would be beneficial for layers during the early laying period as it resulted in the same performance and egg quality as the HE diets without β-mannanase supplementation.

  The study evaluated effect of strain on external and internal egg indices of two strains of Japanese quails (Cinnamon Brown (CBS) and Panda White (PWS) Strains)). 300 birds per Strain were reared in a Completely Randomized Design in an intensive system of management practice with ad libitum feed and water for 10 weeks. Strains were considered treatments. 300 eggs were used for  External (Egg Weight (EW), Egg Length (EL), Egg Width (EW), Eggshell Weight (SW), Shell Thickness (ST) and  Internal (Yolk Height (YH), Yolk Diameter (YD), Albumen Weight (AW), Albumen Diameter (AD), Albumen Height (AH), Haugh Unit (Hu)) egg parameters. Data were subjected to ANOVA of SAS Ver.9.2. Strain significantly (p < 0.05) affected all external egg parameters of Japanese quails except EW measured. The mean values obtained in EL (2.90 ± 0.01 cm) and ED (2.47 ± 0.01 cm) for PWS were significantly (p < 0.05) higher than that of CBS with 2.86 ± 0.01 (EL) and 2.36 ± 0.0 (ED) while 0.82 ± 0.01 g (SW) and 0.11 ± 0.02 cm (ST) for CBS were higher (p < 0.05) significantly than 0.80 ± 0.01 g (SW) and 0.07 ± 0.01 (ST) for PWS. Strain significantly (p < 0.05) influenced all internal egg parameters of Japanese quails exception of YH and YW measured. CBS had higher mean values of 3.25 ± 0.03 cm (AD), 2.35 ± 0.01 cm (YD) and 1.42 ± 0.06 (YC) than PWS with 3.14 ± 0.02 cm (AD), 2.30 ± 0.01 cm (YD) and 1.16 ± 0.03 (YC) while PWS was superior in AH (0.42 ± 0.01 cm), AW (1.77 ± 0.04 g) and Hu (62.10 ± 0.12%) compared to CBS with AH (0.40 ± 0.00 cm), AW (1.66 ± 0.03 g) and Hu (60.67 ± 0.38%). However, CBS had a better external egg quality because of the heavier and thicker shell mean which protect the internal egg contents while PWS performed better in internal egg parameters as Hu qualifies a good quality egg. In conclusion, Cinnamon brown strain of Japanese quails should be reared for egg production purpose as it has better external egg quality to protect the internal egg contents.

 This study aimed to evaluate the increasing levels (0, 1, 2, 3 e 4%) of fish by-product meal in diets for laying hens on performance, egg quality and economic analysis. A total of 160 Dekalb White hens with 52-wk old were distributed in a completely randomized design with five treatments and four replicates of eight birds each. The experiment lasted 84 days divided into four periods of 21 days. Estimates of fish by-product meal levels were determined by polynomial regression. Differences (p < 0.05) were detected for all variables of performance, in egg weight, yolk and albumen percentage, yolk and albumen height, feed cost and production cost, in which the inclusion of fish by-product meal in the diets showed better results. It can be concluded that fish by-product meal can be used in diets for hens as alternative feed, with better results in egg production, feed conversion, egg weight, yolk-albumen ratio and a reduction in feed cost and production cost.
