BookPublisher: 1997Subject(s): Department of Livestock ProductionDDC classification: 0525,T Dissertation note: This experiment was designed to compare different male and female progeny of the opposite male and female grand parent meat line breeders of ROSS-I and AVIAN strains with commercial broiler chicks of the same strains.
The objective of the experiment was to ascertain the genetic potential for the growth of these different lines of strains and their use as a commercial broiler.
The following observations were recorded on; Average feed consumption, Average weekly body weight gain, Average feed efficiency, Average dressing percentage, Mortality (if any) and Economics of meat production.
A total of 180 one -day old chicks purchased from local market were divided into six groups i.e. A having male chicks of female grand parent meat line of Ross-I strain, B having female chicks of male grand parent meat line of Ross strain, C having commercial broiler chicks of Ross strain, D having male chicks of female grand parent meat line of Avian strain, E having female chicks of male grand parent line of Avian strain and F having commercial broiler chicks of Avian strain. Chicks were reared for a period of 42 days (6 weeks) under identical managemental conditions. Same rations (Starter and Finisher) were fed to all the groups.
The results indicated that there was difference (P<0.01) in feed consumption among various groups. Group E containing female chicks of the male grand parent line of Avian strain consumed highest feed (3997 gms) during 0-42 days. It was also noted that weight gain amongst all the groups from 0 to 42 days was different (P<0.01). Highest weight gain was recorded in group E having female chicks of the male grand parent meat line of Avian strain.
The FCR of groups A, B, C, D, E and F during starter and during finisher phase was difference (P<0.05). However, the efficiency of feed utilization was highest in group E. Dressing percentage of different groups was not different (P> 0.05).
The economic evaluation of all the six groups for meat production showed that the birds of group E having female chicks of male grand parent line of Avian strain proved to be the most economical whereas birds of groups B having females of male grand parent line of Ross strain proved 2nd during grading.
RECOMMENDATIONS
The overall picture of the trail reveals that male and female progeny of the opposite male and female grand parent lines can be used as commercial broilers.
