Factors Affecting Quality and Quantity of Egg Production in Laying Hens: A Review
Egg shell quality and egg internal quality are of major importance to the egg industry worldwide. This review covers the formation of the hen’s egg and ways of measuring egg shell quality and egg internal quality. Egg shell quality may be measured as egg size, egg specific gravity and shell color, shell breaking strength, shell deformation (destructive or non-destructive), shell weight, percent...
متن کاملImpacts of Limestone Multi-particle Size on Production Performance, Egg Shell Quality, and Egg Quality in Laying Hens
This experiment was conducted to evaluate the effects of single or multi-particle size limestone on the egg shell quality, egg production, egg quality and feed intake in laying hens. A total of 280 laying hens (ISA brown) were used in this 10-wk trial. Laying hens were randomly assigned to 4 treatments with 14 replications per treatment and 5 adjacent cages as a replication (hens were caged ind...
متن کاملEffects 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 ...
متن کاملNano-calcium carbonate: Effect on performance traits and egg quality in laying hens
A ten-week trial was carried out to determine the effect of different levels of nano-calcium carbonate (NCC) on egg production performance and egg quality. A completely randomized experiment was designed comprising 6 treatments, each with 4 replicates of 5 hens. Groups 1 and 2 were fed diets containing 8.06% and 6.045% calcium carbonate (CC) as positive and negative control respectively. Groups...
متن کاملS83 Egg Shell Colour in Free Range Laying Hens
Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...
