摘要

Present study was aimed to evaluate the hatching traits and subsequent performance of broilers strains under the intermittent and continuous light regime during incubation. In total, 2250 eggs from Hubbard classic, Cobb-500, and Ross-308 strains (750 eggs from each of same age breeders) were incubated under three different light durations. First treatment was the incubation totally under darkness where no light was able to penetrate in the assigned section of machine. In the second treatment, eggs were incubated at 12 h of lightness and 12 h of darkness. In the third treatment, the eggs received lightning of 24 h. Data were collected for hatching traits and hatch window, growth performance, welfare aspects, and meat quality. A two-way factorial analysis was performed using SAS software applying Duncan's multiple range test. The results showed that hatching traits were improved when Hubbard breeder eggs were provided with light period of 12 h. However, gait score was non-significantly different among the treatment. The meat quality was better in Hubbard broilers obtained after 12 h of intermittent light during incubation. Blood biochemistry was also improved in Hubbard broilers of 12 h of light duration. It was concluded that 12 h of light period during incubation is beneficial for getting better hatchability and subsequent performance of Hubbard broilers.
