Abstract

An eight weeks restricted feeding trial was conducted to investigate the effect of restricted feeding and strain on the growth performance and haematological parameters of two strains of pullet chicks. Five hundred and forty chicks comprising of Isa Brown (270) and Bovans Nera (270) strains were assigned to six treatments arranged in a 2 x 3 factorial arrangement of Isa Brown and Bovans Nera on ad libitum (R ), skip-a-day (R ) and skip-2-days (R ) restrictions per week, respectively. Final live weight and weight gain of pullet chicks reduced (P < 0.05) with increasing level of feed restriction. Chicks on ad libitum showed improved (P<0.05) final live weight and weight gain. Results showed significant (p<0.05) reduction in feed intake and body weight of chicks due to restricted feeding. The birds maintained on R feed restriction group recorded the highest significant (p<0.05) values of final body weight (544.57g), feed intake per day (33.70g/day) and daily weight gain (9.82g/day). R birds recorded significantly (p<0.05) higher values of final weight, feed intake and weight gain when compared with R birds with final body weight of 480.84g, daily feed intake of 28.42g/day and daily weight gain of 8.48g. Furthermore, Bovans Nera pullet chicks recorded significantly higher (p<0.05) final weight and daily weight gain when compared with the Isa Brown birds of same age. The R pullets had significantly higher (p<0.05) white blood cells when compared with the R and R birds. Heterophil/lymphocyte ratio (0.52) was  significantly (p<0.05) lower with the Isa brown birds.
