Abstract
A comparison of production potential and egg characteristics of birds of
Lyallpur Silver Black (LSB). Fayoumi (FAY) and Rhode Island Red (RIR) breeds was
conducted. Ninety nine birds, 33 from each breed (30 females and 3 males), were
used as experimental birds. The birds of each breed were divided into three
experimental units (10 females + 1 male), making a total of nine units from the
breeds under study (3 units/breed). All the experimental birds were placed on a
layer ration. Observations on egg production, feed consumption, egg weight and
egg quality characteristics viz. shell thickness, shell weight, breaking
strength, albumen diameter, albumen weight and yolk weight were recorded. The
data thus collected were utilized for the calculation of FCR, Haugh unit and
yolk index values. Maximum egg production and egg
weight were noted in the RIR birds. RIR birds also used their feed more
efficiently, both on per dozen eggs and per Kg egg mass produced basis, than
other breeds. Feed consumption was higher in Fayoumis than other breeds. Maximum
breaking strength, shell weight, shell thickness and yolk index were observed in
LSB birds. Haugh unit values were non-significantly different amongst all the
breeds. Based upon these results, it may be concluded that the RIR birds
exhibited better production potential, whereas LSB birds produced eggs with
better egg quality characteristics than other breeds.
