Abstract :
The response of ross Brown egg layers to the addition of different levels (20,50 and 80 g kg-1) of maize oil in feeds containing 4.6 and 6.4 g kg-1 of sulphur amino acid (SAA) was studied.Each diet was fed to 12 replicates of eight birds at 37 wk of age for three 28-day periods.Data were collected and analyzed for three 28-day periods.Egg components were determined at the beginning,week eight and wk 12 of the experiment.Samples of egg yolk were analyzed for lipid.Added maize oil increased egg weight and egg output significantly at both levels of dietary SAA.Maximum response was obtained when maize oil was included at level of 50 g kg-1.Supplemental maize oil increased the amount of yolk fat.
