Effect of hen age, enviromental temperature, and oviposition time on egg shell quality and egg shell and serum mineral contents in laying and broiler breeder hens
Original language description
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 endof the laying cycle in laying hens and broiler breeders. Egg shell quality deteriorated significantly at the higher temperature and was lower in broiler breeders than in laying hens. The Ca (P?0.047) and P (P?0.018) contents of the egg shell were significantly higher at the higher temperature. The highest (P?0.028) shell Ca content (352 g/kg) was in eggs laid in the morning, but highest P (P?0.030; 1.43 g/kg) and Mg (P?0.001; 3.88 g/kg) contents were in eggs laid in the afternoon. Broiler breeder egg shells contained significantly more P (P?0.004) and Mg (P?0.001) than did those from laying hens. Serum Ca and P levels remained constant throughout the day whereas serum Mg and Zn levels decreased, the rate of decrease in Zn content being
