Effect of Lemon Juice on the Egg Shell Quality of Layers Subjected to Heat Stress
Heat stress is an effective factor on immune responses, body weight, egg production and egg quality of chickens. The major effect of heat stress is due to decreased food intake and alteration in acid-base balance. During the recent years, efforts to improve laying performance at high temperatures have been relatively successful. Supplementation of the diet or drinking water with special nutrien...

متن کاملTime course of changes in egg-shell quality, faecal corticosteroids and behaviour as welfare measures in laying hens
The aim of this study was to assess the extent to which three non-invasive measures of welfare in laying hens (egg-shell quality, corticosteroid levels as measured from the birds’ faeces and behavioural preferences) were correlated over a period of five days in two groups of birds. One group had access to an enriched test area (bark chips on the floor and a tray of sprouted wheat); the other gr...
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...
