Enzyme Supplementation

This study was conducted to determine the effects of xylanase supplementation of corn/wheat-based diets on the performance and egg quality of laying hens. At 52 wk of age, 180 White Leghorn LSL laying hens were fed 15 diets, consisting of five corn:wheat ratios and three levels of enzyme. None of the treatments affected performance or egg quality, except for egg yolk index and egg yolk color. The egg yolk color was improved by the increase in dietary corn level. It is concluded that wheat can be used instead of corn as an energy feedstuff in laying hen diets. Key words: Egg quality, laying hen, performance, xylanase

The differences in egg production traits in six laying hen genotypes (brown-egg hens Bovans Brown, Bovans Sperwer, ISA Sussex; white-egg hen Dekalb White; laying hens with tinted shells Moravia Barred and Moravia BSL) and the interactions of genotype and oviposition on egg quality were evaluated. The genotype affected the laying rate (P ≤ 0.003), mean sequence length (P ≤ 0.001), and time of oviposition (P ≤ 0.001). The brown-egg genotypes laid eggs approximately 1 h earlier than the white-egg genotypes and approximately 2 h earlier than the tinted-egg genotypes. Egg shell strength was the lowest in tinted-egg genotypes (P ≤ 0.001) and declined with the time of oviposition (P ≤ 0.002). Egg shell percentage (P ≤ 0.011) and thickness (P ≤ 0.011) were affected by the interaction of genotype and oviposition. None of the effects affected egg weight; however, the proportion of egg components was significantly influenced by the interaction of genotype and oviposition. The study confirmed that the differences in the egg production and egg quality of various genotypes are associated with the laying pattern.

Effect Of Treatment

A total of 480 Babcock White Leghorn hens (65 wk of age) were randomly assigned to one of five diets [wheat-based control (C), 10 g t–1 Carophyll Red® (CR), 20 g t–1 Carophyll Yellow® (CY), 10 g t–1 CR + 20 g t–1 CY (CR + CY), 80 kg t–1 crab meal (CM)] for 60 d. There was no effect of treatment on egg production. There was an increase in red pigmentation (a* score) on day 45 among treatments supplemented with CR, CR + CY and CM when compared with C and CY. The laying hen was capable of depositing the natural carotenoid supplied by the CM into the egg yolk. Key words: Laying hen, crab meal, carotenoids, astaxanthin, yolk pigmentation

A total of 45 laying hens were fed a control diet, or one of four diets containing 50 g kg–1 fish silage and different levels of fish fat (1.8, 8.8, 16.8 or 24.8 g kg–1), to determine the effect of fish silage and fish fat in the diet on performance and egg quality. Fish silage did not affect feed intake, egg production, fatty acid composition of yolk, yolk color or sensory quality of eggs, compared with the control. The diets with 16.8 or 24.8 g kg–1 fish fat decreased feed intake (P < 0.001), egg production (P < 0.001), and hen-day egg production (P < 0.04), and increased yolk color index (P < 0.003). The proportions of the fatty acid C22:1 (P < 0.001), and PUFA as the sum of C18:2 n-6, C20:5 n-3, C22:5 n-3 and C22:6 n-3 (P < 0.02) in egg yolk were highest for the fish silage diets with 24.8, 16.8 or 8.8 g kg–1 fish fat, and lowest for the diet with 1.8 g kg–1 fish fat. Proportions of C18:1 (P < 0.001) and C20:1 (P < 0.001) were lowest for the diets with 16.8 or 24.8 g kg–1 fish fat. Egg yolk cholesterol did not differ among treatments. The diet with 16.8 g kg–1 fish fat resulted in a more intense egg albumen whiteness as measured by the sensory study, compared with the other diets (P < 0.05). There was a linear relationship between dietary fish fat level and increased off-taste intensity of egg yolk (P< 0.03). Key words: Fish silage, fish fat, laying hens, egg production, egg quality

The research aimed to determine the characteristics and quality of egg of commercial laying hens fed ration supplemented with garlic (Allium sativum) powder. The research used Completely Randomized Design (CRD) with five treatments and four replicates (5 hens each) for a total of 100 brown laying hens strain MB 402. Garlic powder contained 24.62% crude protein, 38.81% fat, and 1.74% crude fiber. The treatments of garlic powder ration were 0, 2, 4, 6, and 8%. The treatments performed were dietary, with R0 = 100% based diet (BD); R1= 98% based diet (BD) + 2% garlic meal (GM); R2= 96% based diet (BD) + 4% GM, R3 = 94% based diet (BD) + 6% GM, R4 = 92% based diet (BD) + 8% GM. The study was conducted during eight (8) weeks. Collected data were quality, weight, shell weight, albumen weight and shell thickness of eggs. Data was analyzed with Analysis of Variance (ANOVA) and continued with Duncan’s Multiple Range Test (DMRT). The results showed that 8% garlic powder ration increased weight and albumen weight of eggs. There were no significant effect of treatments in yolk weight, shell weight and shell thickness of eggs. Garlic powder supplementation on laying hen ration affected egg weight and albumen weight. The addition of garlic powder on laying hen ration of up to 4% increased egg weight. Albumen weight increased until garlic powder supplementation of up to 8%. It is recommended the use of 8% garlic powder supplementation on lying hen ration without negative effects on egg quality.

Completely Randomized Design

This study evaluated the effect of pequi peel meal in the diet for laying hens on performance and egg quality. Hy-Line® Brown hens (n=160) aged 55 weeks with 1642±63g body weight were distributed in a completely randomized design with five treatments and four replications of eight birds each. The treatments consisted of isometric substitution of corn by pequi peel meal at 0, 2.5, 5.0, 7.5 and 10%. The performance and internal and external egg quality were evaluated. Egg production, egg mass and feed conversion worsened linearly with increasing replacement of corn with pequi peel meal, while the yolk color increased linearly. The other variables related to performance and internal and external egg quality were not significantly affected by the treatments. It can be concluded that the use of pequi peel meal replacing corn in laying hen diet does not change the internal and external egg quality, improves the pigmentation of egg yolk, and impairs performance of laying hens.

This study aims to examine the effect of giving Bacillus subtilis probiotics in laying hens on improving the quality of internal and external eggs with differences in shelf life. A total of 60 laying hens were divided into 4 treatment groups, namely P0 as a control that was not given probiotic B. Subtilis, P1 feed was added 0.005 grams B. Subtilis, P2 feed with added 0.01 grams B. Subtilis, P3 feed added 0.02 grams B. Subtilis then the eggs produced are stored for 1 day, 5 days and 10 days. The results of this study indicate that the administration of B. Subtilis probiotics with a concentration of 0.02 grams affects the increase in egg weight, egg yolk index value and HU values. The addition of B. Subtilis probiotics to racial feed can improve egg quality.

Enzyme Supplementation

The present study was conducted to assess the effect of supplementation of Multi-enzymes with lysophospholipids on production performance of pure line White Leghorn layers. Body weights before and after the experiment did not differ significantly across the experimental diets. Irrespective of the dietary treatments, the birds gained 3.83 per cent of live weight relative to its initial body weight. Mean per cent Hen housed egg production was significantly (Pis less than 0.05) higher in diet supplemented with 0.10 MEC-L than other groups. Mean egg weight and average daily feed consumption during 25 to 35 weeks of age indicated no significant effect of enzyme supplementation. Average daily feed consumption per bird in control, 0.05 % and 0.1% multi-enzyme supplemented groups was 108.13, 105.66 and 107.67 g respectively and birds offered control diet recorded numerically more feed intake than enzyme supplemented groups. Comparatively low feed per egg was observed in 0.10 per cent group followed by 0.05 per cent group which offers economic benefits than control diets. However, the egg quality traits between different dietary enzyme supplementation groups showed no significant difference.
