We examined the effects of light intensity (LI) from photostimulation to 45 wk of age on egg production parameters and egg size characteristics and on ovarian and carcass morphology at sexual maturity and 45 wk of age in four layer strains. Floor housed pullets were raised in a light-tight facility from 1 d of age until housing in individually illuminated cages at 17 wk of age. Two white egg st...

This study was carried out to determine the dietary supplementation of organic zinc on feed intake (FI), conversion ratio (FCR), egg production (EP), mass (EM) and quality. A total 120 ISA-Brown layers aged 20 weeks were used in this study. Hens distributed randomly four treatments (30 hens each) with three replicates. The supplemented into basal diet at different concentrations as follows; (T1...

Keel bone fractures and deviations are one of the major welfare and health issues in commercial laying hens. In non-cage housing systems like aviaries, falls and collisions with perches and other parts of the housing system are assumed to be one of the main causes for the high incidence of keel bone damage. The objectives of this study were to investigate the effectiveness of a soft perch mater...

Two hundred fifty-six 18-wk-old Shaver White and ISA-Brown pullets were fed commercial diets containing either 0 or 10% flaxseed in order to study the long-term effects of feeding flaxseed on hen performance and egg production parameters. Performance was monitored over 10 consecutive 28-d periods. Flaxseed was introduced gradually at 28 wk of age and was maintained until hens were 53 wk of age,...

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...

The layer poultry is an important activity for food production with high biological value. Measuring egg quality has great relevance to ensure safety and products consumers. Thus, the objective was evaluate physical of four laying hen’s strains. Were used 864 eggs from hens’ lines (Hisex Brown®, Hy-Line Isa Label®, Lohmann Brown®). experimental design completely randomized composed treatments (...
