Relationship of hemoglobin types and blood groups with bodyweight and dimensions in unimproved Awassi ewes

The study was conducted on 216 ewes of unimproved Awassi sheep breed to determine the effect of hemoglobin type and blood group on body weight and dimensions. Results showed a significant effect (P˂0.05) of hemoglobin type on live body weight, the highest body weight was noticed in ewes with hemoglobin ABHb compared with the lowest body weight which was noticed in ewe group with hemoglobin BHb namely, 43.93 and 36.81 Kg respectively. No significant effect of blood group on live body weight. Interaction among hemoglobin types and blood groups effected significantly (P˂0.05) on body weight , the highest body weight was in group with ABHbR genotype (45.25 kg) while the lowest body weight was in group with BHbD genotype (34.75 kg). Results showed a significant effect (P˂0.05) of hemoglobin type on some of body dimensions. The longest body was in ewe groups with hemoglobin BHb while the shortest body was in hemoglobin type AHb namely,66.5 and 62.43 cm respectively. The highest hip width and heart girth were noticed in group with hemoglobin AHb namely, 29.81 and 99.12 cm respectively while least values were noticed in the group with hemoglobin BHb namely, 27.75 and 95.18 cm respectively. The highest values were noticed in group with blood group R namely, 32.25 and 72.66 cm respectively. Interaction among hemoglobin types and blood groups effected significantly (P˂ 0.05) on body dimension, ewes with BHbB genotype had a longer body than the other groups (68.50 cm). The group with AHbR had a wider shoulder than the other groups (31.25 cm) while the group with BHbR had a wider hip and higher shoulder compared with the other groups.
