The effects of different breeding systems on egg productivity and egg quality characteristics of Rock Partridges.

This study was carried out to investigate the effects of different breeding systems (breeding on the ground and in the cage) on the egg production and egg characteristics of Rock Partridges. Egg production values of the ground and cage system groups were determined as 41.30 and 49.40%, respectively, and this difference was found to be significant (P < 0.05). The weight values of the eggs were 2...

Effects of Different Dietary Vitamin Combinations on the Egg Quality and Vitamin deposition in the Whole Egg of Laying Hens

The Effects of Dietary Calcium Sources and Vitamin D3 on Egg Quality and Performance in Laying Hens

This experiment was designed to evaluate the effects of different sources of calcium at different rates and cholecalciferol(Vitamin D3) on the performance and egg quality of Hy-line W-36 Laying hens. In this study a total of 648 hens were managed in a completely randomized design using a factorial arrangement of 3 × 3 × 2 treatments, with three calcium sources (oyster shell, OS; ground limeston...

Effects of laying hens housing system on laying performance, egg quality characteristics, and egg microbial contamination

The objective of this study was to compare the performance, egg quality, and microbial contamination of egg shells from hens maintained in different housing systems, such as conventional and enriched cages, litter, and aviaries. The housing system significantly (P < 0.001) influenced the performance characteristics. The highest egg production, lowest daily feed consumption, and feed conversion ...

effect of different levels of canola meal and fat sources on performance and egg quality in laying hens

this experiment was carried out to study the effects of different levels of canola meal of different fat sources on the egg quality, performance as well egg yolk cholesterol during the first 12 weeks of age in laying hens (hy-line w-36). throughout the experiment a total of 432 hens were employed in a completely randomized design in a factorial arrangement of 3×4, with three levels of canola me...
