Abstract

This study was conducted to study the effect of split feeding system on egg production and egg quality of Dandarawi layers during their late phase of egg production cycle.  A total of 100 Dandarawi Layers (12 months old) were divided into two groups. Each group was divided into 5 replicates (10 hens each). The first group was kept as control and fed one diet throughout the day (regular diet with optimum level of energy, protein and calcium). Whereas, the second group was fed according to split feeding system by having access to two diets throughout the day. The first diet (high energy, high protein and low calcium) offered from 6 am to 6 pm, and the second diet (low energy, low protein and high calcium) offered from 6 pm to 6 am. The diet offered throughout the daily hours was higher by 10% energy, 23% protein and lower by 50% calcium than the diet offered throughout the night hours.  Body weight, feed intake, feed conversion ratio, egg production traits, egg quality were recorded, estimated or calculated. The results revealed that the split feeding system did not result in any significant (P>0.05) changes in body weight or body weight change during the experiment period from 12 to 16 months of age. Feed consumption was significantly decreased by 16.1 % and feed conversion ratio was significantly improved by 25 % by following split feeding system. There was a tendency to numerical increase in egg number by 9.47 %, egg laying rate % by 9.5%, and egg mass by 9 % for the split feeding system during the previous period. Split feeding system significantly increased egg length, egg width, albumen weight, albumin height and Haugh units compared with the control group. However, there was no significant influence of split feeding on egg weight, egg specific gravity, shape index, egg yolk quality, albumin%, and eggshell traits. It could be concluded that split feeding of Dandarawi layers at their late phase of egg laying cycle has led to decreasing feed consumption, improving feed conversion ratio, saving in feed cost and increasing egg number and egg mass.
