Magnesium Requirement of the Laying Hen ,

Poultry Science, 1968
Abstract THE quantitative requirement for magnesium by laying hens has not been established. The National Research Council in 1966 listed the growing chicken's requirement as 500 mg. magnesium per kilogram of feed, but gave no estimate of the hen's requirement while Edwards et al. (1961) showed that the phosphorus level of the hen's diet had a marked

The physiological comparison revealed the importance of focusing anti-oxidation function during the peak laying stage in hens based on multi-omics analysis

Animal Nutriomics
With the increase in egg production rate and the coming of peak laying period, some metabolic disorders usually emerge in layers. The current study was conducted to compare the physiological difference between the early laying stage (around 30% laying ...
