Production of laying hens in different rearing systems under hot weather

The parameters studied were: feed intake, egg production per hen day, egg production per housed hen, commercial egg production, egg weight, egg mass, feed conversion per egg mass,

The following variables were studied: feed intake (FI); lysine intake (LI); egg production per bird per day (EPBD); egg production per bird housed (EPBH); production

However, these researchers observed a quadratic effect of chloride levels on egg production, egg weight and feed conversion per egg mass and specific gravity, indicating an

Feed consumption (FC), water consumption (WC), egg production (EP), mean weight of eggs (MWE), mass of eggs (EM), feed conversion per mass of eggs (FCME) and per dozen of eggs

Table 2 - Egg weight (EW), lay percentage (LP), egg mass (EM), feed intake (FI), feed conversion ratio per dozen eggs (FCR/dz), feed conversion ratio per kg egg (FCR/kg), and

Improved egg weight and feed conversion per egg mass were seen when the protein level of the diet was increased, whereas feed intake, laying rate, feed conversion per dozen eggs,

Feed consumption (FC), egg production (Production), egg mass (EM), egg weight (EW), feed conversion by dozen (FCDz) and by egg mass (FCEM) of laying hens fed with ration

There were no significant ( p >0.05) differences on hen day egg production, egg weight, egg mass, unmarketable eggs, feed intake, feed conversion efficiency (FCR), and live
