Abstract EN
This research was conducted at Fedio farm (Faculty of Agriculture, University of Tishreen /Syria) to evaluate the effect of reciprocal hybridization between two Syrian poultry genotypes (Black and Brown) on some productive traits such as weight gain, average fodder consumption, living weight and feed conversion ratio.
Results showed that reciprocal hybridization between the two Syrian poultry genotypes black (Bl) and brown (Br) revealed significant decrease (P < 0.05) in the average of living weight of 49 days old chicks compared to the only brown type.
The living weight at 49 days old of the genetic groups was Br X Br (529.99 g), Bl X Bl (415.14 g), Bl X Br (397.24 g) and Br X Bl (413.60 g).
The average of daily weight gain decreased significantly (P < (0.05 in crossbreds chicks compared to the only brown type; But this decrease was non-significant compared to the black type, the average of daily weight gain was Br X Br (10.05 g/bird/day), Bl X Bl (7.70 g/bird/day), Bl X Br (7.35 g/bird/day) and Br X Bl (7.68 g/bird/day).
The crossbreeding between brown male with black female revealed non-significant decrease in the average daily fodder consumption by 4.48 and 6.63 g/bird/day, respectively compared to the black and brown types.
Whereas crossbreeding between black male with brown female revealed non-significant increase in this average by 1.45 g/bird/day compared with the black type, and non-significant decrease by 0.7 g/bird/day compared to the brown type.
While crossbreeding between black male with brown female revealed significant increase in feed conversion ratio (FCR) by (1.16 kg feed /kg meat) compared to the brown type, but the crossbreeding between brown male with black female revealed significant decrease in FCR by 0.57 compared to the black type.
