Egg Iron Enrichment in Response to Various Levels of Pomegranate by-Product in Laying Hen Diet
The present study was conducted to investigate the effects of different levels of pomegranate by- product (PBP) on performance, egg quality and blood parameters in laying hens. A total of 144 Bobze layer hens from 44 to 56 weeks during 12 weeks were randomly assigned into 4 treatments including 0 (control, corn and soy bean meal), 4, 8 and 12% of PBP, with 4 replicates and 9 layers in each.

متن کاملEffect of hen age, environmental temperature, and oviposition time on egg shell quality and egg shell and serum mineral contents in laying and broiler breeder hens
The aim of the study was to evaluate egg shell quality characteristics, mineral content in the egg shell, and serum mineral concentration during the egg formation process as influenced by oviposition time and ambient temperature at the beginning and end of the laying cycle in laying hens and broiler breeders. Egg shell quality deteriorated significantly at the higher temperature and was lower i...
