Three density levels of 1114,928 and 743 sq cm/bird were tried. The experiments were identical in all respects except for season.
The climatic variables during the first experiment was not favourable when compared to the second experiment. Data on weight gain revealed no significant difference between the three treatments. However, broilers reared with a floor space allowance of 1114 sq cm/bird had higher final body weight. The feed consumption, ready to cook yields and per cent mortality did not exhibit statistically significant differences between the density treatments. The per cent litter moisture did differ significantly (p<0.05) between the three density treatments. The high density group had the highest followed by medium and then low density treatment.
The climatic variables during the second experiment reflected of more comfortable conditions for the birds. Data on body weight gains between treatments exhibited statistically significant (p<0.05) differences. The low density group had the highest weight gains followed by medium density group. The high density group had the lowest weight gain. There was no significant difference in feed consumption between treatments. Per cent ready-to-cook yield did not differ significantly. Per cent litter moisture content exhibited statistically significant (p<0.05) difference between treatments.
Data on weight gain and feed consumption between the two experiments revealed statistically significant difference. The monsoon reared birds gained higher body weight and consumed more feed in all treatments. Mortality percentages did not reveal any seasonal effect. Approximately there was an increase of 10% litter moisture in monsoon season for all the treatment groups. Per cent ready-to-cook yield revealed statistically significant difference between the two seasons.
