Comparative study of growth performance, meat quality and haematological parameters of Fayoumi, Rhode Island Red and their reciprocal crossbred chickens

Abstract

A total of 2001 unsexed day-old-chicks of each Fayoumi, Rhode Island Red (RIR), RIR × Fayoumi (RIFI) and Fayoumi × RIR (FIRI) were obtained from hatchery of Poultry Research Institute, Rawalpindi. The birds were maintained on deep litter system for a period of 20 weeks. The results revealed that the average day old weight was highest in RIR and FIRI, intermediate in RIFI and lowest in Fayoumi chickens. The RIR breed consumed more feed and gained maximum (P<0.05) weight gain than those of Fayoumi and crossbred chickens at all ages of growing phase. The poor (P<0.05) feed conversion was observed in Fayoumi and better feed conversion was recorded in RIR and both crossbred chickens. The crossbred chickens had lowest (P<0.05) mortality than purebred chickens. The highest dressing percentage was observed in FIRI (62.60) followed by RIFI (62.40%), RIR (57.50) and Fayoumi (54.08) chickens. The breast and thigh meat composition had non-significant (P>0.05) difference among pure and crossbred chickens. There was non-significant (P>0.05) difference in haematological values among all chickens. The total erythrocyte number, haemoglobin and packed cell volume increased with the advancement of age. However, erythrocyte sedimentation rate, mean corpuscular volume and mean corpuscular haemoglobin values decreased gradually with the advancement of age. It may be concluded that crossbred chickens gained better body weight than Fayoumi and moderate than RIR chickens with lower mortality. The crossbred chickens of FIRI showed better performance in all traits than crossbred chickens of RIFI.

The Growth Performance, Carcass Characteristics, and Meat Quality of Egg-Type Male Growing Chicken and White-Mini Broiler in Comparison with Commercial Broiler (Ross 308)

“…Growth performance of EM, WB, and CB increased under identical diet and feeding conditions are presented in Table 2 . The ADG and gain:feed were the highest in CB, intermediate in WB, and the lowest in EM ( p <0.05), consistent with previous reports ( Khawaja et al ., 2012 ; Lichovnikova et al ., 2009 ; Lonergan et al ., 2003 ). Huque et al .…”

Comparative study of growth performance, meat quality and haematological parameters of three-way crossbred chickens with reciprocal F1 crossbred chickens in a subtropical environment

“…Our previous work on the growth pattern in chickens of reciprocal crossing between RIR and Fayoumi breeds has been published recently (Khawaja et al 2012). The results showed that crossbred chickens of FIRI (Fayoumi male)RIR female) showed better performance in all traits than crossbred chickens of RIFI (RIR male )Fayoumi female).…”

Performance differences of Rhode Island Red, Bashang Long-tail Chicken, and their reciprocal crossbreds under natural cold stress

“…Previous studies have reported that White Leghorns crossed with Bedouin fowl (a breed that is adapted to desert conditions and can withstand both hot summers and cold winters) can produce chickens that are similarly well adapted [ 6 ]. Other studies report that Fayoumi, a heat tolerant breed, can be crossed with other breeds to produce crossbreds with improved adaptation and fitness traits [ 11 ]. Thus, crossing BS with a commercial line to produce cold tolerant high performance laying chickens might be feasible.…”
