| Abstract | ||
| This study was conducted in the Agricultural Research Center of American University of Beirut from 11/3 to 21/4/2005 to evaluated the performance of two commercial broiler hybrids ( Cobb 500 and Hubbard Classic )for investigating the more respond one of these hybrids to breeding within environment conditions under control .400 of one- day- aged unsexed birds were used ( 200 for each hybrid ). The results of the statistical analysis of data collected during the experiment period from 1_21 and 22_42 days-old showed that the performance of the Cobb 500 hybrid was significantly ( P ≤ 0.05 ) superior to that of Hubbard Classic . The live body weight for Cobb 500 was heavier in that , the mean reached ( 690.5 and 2210 g ) at 21 and 42 day age respectively , while Hubbard weights ( 618.75 and 2095.75 g ) at both ages respectively. The type of hybrid as well had significant effect ( P ≤ 0.05 ) on the feed conversion where the birds of hybrid Cobb 500 were superior in this trait than those of Hubbard Classic , the feed conversion coefficient of two types of hybrids were (1.495 and 1.548 g feed intake / g weight gain ) during the starter period and ( 2. 067 and 2.120 g feed intake/ g weight gain ) during the growth period for both hybrid respectively.The mortality percentage was significantly low in Cobb 500 hybrid than Hubbard Classic during the total breeding period where was (2.89 and 14.88 % ) for both hybrids respectively .The results of yield factor of the total breeding period showed that significant differences to hybrid Cobb 500 vs Hubbard Classic revealed and were (269.8 and 214.42 ) for both respectively . According we can conclude that the hybrid Cobb 500 was superior in all essential production indicatory than Hubbard Classic . | ||
