Performance of Cobb 500 and Hubbard broilers on different treatment

• Broschiertes Buch

Produktbeschreibung

Fertility is not dependent on egg storage treatments employed. Egg storage temperature at 16 0C and fumigation significantly (P0.001) improved hatchability in both breeds. Hubbard broiler strain grew faster (P 0.01) than Cobb 500 during the finisher and entire growth period. Cobb 500 seems high in FCR in both interactions. FCR seems high (P0.05) in Cobb 500 chicks hatched from eggs not fumigated and exposed to medium pre-incubation temperature than all the rest 3 way interaction, but Hubbard showed the lowest in the same treatment combination during starter period. Cobb 500 has heavier breasts and liver weight, while Hubbard had heavier abdominal fat. Fumigation and strain significantly (P0.05) affected mortality during starter and finisher phases, respectively. Fumigation and medium temperature (about 16 0C) is important for better hatching yield and post-hatching performance regardless of the strain. Furthermore, the result of the present experiment revealed that hay-box used for layers can be adopted for brooding broiler chicks with appropriate modification of dimension, which require further research.
