| Abstract: |
A crossbreeding experiment was executed between the local strain of Golden Montazah (GM) and a standard breed of White Leghorn (WL). Data of 5029 chicks were produced by 79 sires and 441 dams from five genetic groups (two foundations of GM and WL, three crossbreds of GM x WL, (GM × WL)2 and ((GM× WL)2)2. Body weight of these chicks were individually recorded in grams at hatch (BW0), 4 (BW4), 8 (BW8), 12 (BW12) and 16 (BW16) weeks of age. Daily gains in weight (grams) during the age intervals of 0-4 (DG4), 4-8(DG8), 8-12(DG12) and 12-16(DG16) weeks were calculated. Single-trait animal model analysis was used to analyze the data of body weight and daily gain traits. Results showed that GM strain had superiority (p |
