| dc.description | Poultry keeping in the past was a sideline occupation. In some communities, the fowl is still
used as in the past, as a means of knowing the time. Today, poultry keeping has developed to
the level of commercial enterprise involving thousands of birds. Large poultry units have
replaced small one’s while more efficient strains and breeds of birds, balanced feeds,
intensive housing and better poultry equipment have come into used. The poultry industry has
become a diverse industry with a variety of business interests such as egg production, meat
production, hatchery and poultry equipment business. However, the decision to start a poultry
farm depend on whether or not the farmer is aware that poultry production is one of the most
promising sources of additional income, protein intake and quick returns from investments.
Poultry can be established with a minimum cost and as a side project. Moreover, they can
feed for themselves on free range without much care. | en_US |
| dc.description.abstract | The present study was conducted on Broiler Strains (Cobb-500 & Arbor Acres) maintained
atKazi farms located in Northen part of Bangladesh to compare the egg production
performance, Mortality rate, Hatchability and feed (kg) per hatching egg from 25 to 64 weeks
of age.The highest egg production of Cobb-500 were observed in 30 to 34 weeks of age
(79.76 ± 0.893) and the lowest in 60 to 64 weeks of age (46.76 ±0.724). The highest egg
production of Arbor Acres were observed in 35 to 39 weeks of age (75.12 ± 0.257) and the
lowest in 60 to 64 weeks of age (47.88 ±0.86). There were no significant difference (p<0.05)
in egg production between Cobb-500 and Arbor Acres strain (79.76 ± 0.893 and 74.24 ±
0.851) at 30-34 weeks of age and (74.92 ± 0.257and 75.12 ± 0.25) at 35-39 weeks of age but
significant difference between two strains at the age of 25-29, 40-44, 45-49, 50-54, 55-59,
and 60-64 weeks.The highest mortality of Cobb-500 were observed in 60 to 64 weeks of age
(0.9600
0.07543) and the lowest in 40 to 44 weeks of age (0.2900
0.02470). The highest
mortality of Arbor Acres were observed in 60 to 64 weeks of age (1.2260
0.05519) and the
lowest in 40 to 44 weeks of age (0.4800
0.0446). There were no significant difference
(p<0.05) in mortality between Cobb-500 and Arbor Acres strain at different weeks of age
.The highest hatchability of Cobb-500 were observed in 35 to 39 weeks of age (92.0680
0.11249) and lowest in 60 to 64 weeks of age (75.7640
0.34243). The highest hatchability
of Arbor Acres were observed in 40 to 44 weeks of age (89.0140
0.20061) and the lowest in
60 to 64 weeks of age (73.4300
0.35355). There is no significant difference (p<0.05) in
hatchability between Cobb-500 and Arbor Acres strain (92.4060
.10260 and 88.1880
.42407) at 35 to 39 weeks of age and (92.0680
.11249 and 89.0140
.20061) at 40 to 44
weeks of age but significant difference was found between two strains at the age of 25-29,
30-34, 45-49, 50-54, 55-59 and 60-64 weeks. There were no significant difference (p<0.05)
in feed requirement of per hatching egg between Cobb-500 and Arbor Acres strain at age of
30-34, 40-44 and 45-49 weeks but significant differences were found among other weeks. In
conclusion Cobb-500 strain was appeared to be most economic to rear than Arbor Acres in
response their performance record. | en_US |
