Abstract

This experiment was conducted on crosses derived from broiler breeders (Arbor Acres) and native chickens (Fayoumi breed and Gimmizah strain) at marketing age (8 weeks) of age. A total of 200 individuals from the crosses (100 for each cross “50 males + 50 females”) from 5 broiler breeder with 25 Fayoumi female and 25 Gimmazh female by artificial insemination, and blood samples were collected randomly through venipuncture total sample=42 each crosses. The blood parameters analyzed included total protein, albumin, triglycerides, cholesterol, HDL, LDL, phosphorus, calcium, superoxide dismutase, ALT, and AST.  A one-way and two ways ANOVA test was applied to compare the means (p < 0.01) of blood parameters across groups. Showed that the mean body weight (AA x FM) and (AA x GM) was 28and 30gm, respectively. In this study, (AA x GM) showed a heavier body weight (1180 gm/bird) at 6 weeks and 8 weeks (2000gm) in comparison with other native chicken genotypes. The findings revealed that total protein (TP) plasma levels in parent groups were significantly higher than those in F1 crosses. Triglyceride (TG) values also showed significant differences between parent breeds and F1 crosses, with parent breeds exhibiting higher values than F1 crosses. The highest TG value was observed in Gimmizah (GM) females, while the lowest was in (AA × GM) females. Additionally, phosphorus concentration was significantly higher in GM♀ parent strain compared to other parent breeds and their crosses. At 8 weeks of age, the plasma level of AST was highest in Arbor Acres (AA) males and lowest in (AA × GM) males. In conclusion, this study recommends crossing broiler breeder males with native Gimmizah strain females to improve the physiological performance of chickens
