The study was conducted to investigate the effect of dietary diatomaceous earth (DE) on egg quality traits in deep litter hens. A total of 280 Lohmann Brown pullets were at 20 weeks of age divided into 4 groups. Three groups were fed on one of the three experimental diets supplemented with 2%, 3% or 4% DE, while the fourth group was fed on a control diet without DE supplementation. Each group had seven replicates of 10 birds. One egg was collected randomly per replicate (for a total of 7 eggs per group), weighed and determined for: yolk weight, albumen weight, eggshell weight, eggshell thickness, specific gravity, albumen height, yolk height, yolk colour and Haugh unit. Findings showed that DE supplementation resulted into significant (p<0.05) increase in eggshell weight and yolk height. Dietary supplementation with DE in the current study was, however, not effective on other egg quality parameters such as on eggshell weight percentage, egg specific gravity, yolk colour and Haugh unit. However, results of the study also showed that DE supplementation improved significantly (p<0.05) egg quality especially by improving viscosity as flocks grew older as compared to younger flocks. Further research should focus on the effect of dietary DE on eggshell and bone strength of layer birds. Research should also explore the interactions among the minerals found in DE (e.g. calcium, phosphorus and magnesium) and how these interactions affect egg quality in laying hens.

The Relationship

Aim: This study was conducted to identify the diversity of feather color and to determine the relationship between plumage color and egg yield as well as eggshell patterns and internal egg quality traits of Japanese quails. Materials and Methods: For investigating phenotypic diversity, a total of 600 quails from five breeding farms were evaluated to record head feather, shank, and plumage color. An on-station experiment was also conducted on 360 laying quails to examine the relationship between plumage color and egg production and egg weight during 24 weeks of laying. Eggs collected during this period were also used for identifying eggshell patterns and examining their relationship with internal egg quality characteristics. Results: Plumage color was primarily wild-type, with the highest proportion being 56.3% (p<0.001). Brown color was also found at a relatively high proportion in the population (16.7%), followed by black color (11.3%). The egg production and laying rate of quails with wild-type and brown plumage colors also significantly (p=0.001) differed from those of quails with other plumage types. Egg weight was also higher in these quail groups, especially than that of quails with yellow plumage color. Four patterns of eggshell were identified, among which spotted and dark eggshells were predominant (45.2% and 43.1%, respectively); however, patterns did not affect internal egg quality characteristics. Conclusion: Plumage color was primarily wild-type in both male and female quails. Egg yield over a 24-week laying period was superior in quails with wild-type and brown plumage colors, whereas a relationship between eggshell patterns and egg quality traits could not be established.

Vitamin C Supplementation

Abstract Endogenous synthesis of vitamin C may satisfy its requirement for laying hens; however, some previous experiments showed beneficial effects of dietary supplementation of vitamin C in laying hens. Thus, the results are still controversial. The objective of the current experiment, therefore, was to investigate the effect of vitamin C supplementation in diets on productive performance, egg quality, relative organ weight, and tibia strength in laying hens. A total of 504 46-wk-old Hy-Line Brown laying hens were allotted to 1 of 6 dietary treatments with 7 replicates in a completely randomized design. Each replicate had 12 hens. Diets were prepared by supplementing the basal diet with vitamin C at the levels of 250, 500, 1,000, 2,000, or 3,000 mg/kg and were fed to hens for 6 wks. Results indicated that increasing supplementation of vitamin C in diets increased hen-day egg production and egg mass (quadratic, P &lt; 0.05), but decreased production of broken or soft-shell eggs (linear and quadratic, P &lt; 0.01) and feed conversion ratio (quadratic, P &lt; 0.05). These positive effects were observable at the supplementation level of 250 mg/kg vitamin C, but there were no further benefits at the greater levels of vitamin C. Increasing supplementation of vitamin C in diets had no effects on egg quality, except for a decrease (quadratic, P &lt; 0.01) in egg yolk color with increasing vitamin C supplementation. The relative weights of the liver, kidney, and spleen were not affected by increasing supplementation of vitamin C in diets. Tibia strength was not influenced by increasing supplementation of vitamin C. In conclusion, dietary supplementation of vitamin C has a beneficial effect on egg production of laying hens. Quadratic responses of increasing vitamin C supplementation in diets reveal that supplementation of 250 mg/kg vitamin C is recommended for diets fed to laying hens at 46–52 wks of age.
