Response of three laying hen genotypes to two dietary calcium levels
Popis výsledku v původním jazyce
The present study aimed to evaluate the effect of two dietary Ca levels in three hen genotypes, ISA Brown, Bovans Brown and Moravia BSL, on their laying performance and quality of their eggs. A higher Ca level significantly increased the hen-day egg production percentage of Bovans Brown and Moravia BSL, while ISA Brown laying hens had the higher egg production percentage at a lower dietary Ca level. No significant effect of dietary Ca level was observed on any internal egg quality measurements except the Haugh unit. However, the dietary Ca level significantly affected some of external egg quality measurements, namely eggshell colour, eggshell weight and eggshell strength. The results of the present study show that laying performance and egg quality parameters responded differently according to hen genotype and dietary Ca level. Bovans Brown and Moravia BSL laying hens required higher levels of Ca to keep egg production high, while the eggshell quality measurements were better at the lower dietary Ca level. Thus, it is recommended to adjust the Ca levels in feed to the nutritional requirements of laying hens.
