Effect Of Different Light Colours And Patterns On The Performance Of Broilers - 1990
Although poultry industry is dynamic for having tremendous potential to produce quality protein from meat and eggs which has a significant impact on the economy of our country. Yet it is not a stable business because a slight variation in environment upsets its profit margins. Different lighting schedules play a prominent role for rearing the broiler birds. In recent years efforts have been made to develop more efficient lighting schedules so as to save the electricity expenditure and to produce cheaper broiler meat.
An experiment therefore, was designed to work out an ideal lighting pattern.
In this experiment two hundred and twenty day old chicks were reared together for the first fifteen days, then one hundred and eighty chicks were randomly selected and subjected to different lighting patterns and clours of red, green and normal lights. They were divided in to groups i.e. A,a B,b and C,c exposed to continuous and intermittent pattern of red, green and normal light.
The maximum weight gain was obtained by group subjected to green continuous lght and the lowest by group exposed to normal intermittent light. Likewise the maximum amount of feed was consumed by the group provided normal continuous light and minimum by the group exposed to red intermittent light. So far as the FCR is concerned, it was comparatively better in green continuous light group and poorest in normal intermittent light group. Another purpose of this experiment was to observe whether coloured and intermittent pattern of lights have better effects than that of the normal ones. The chicks subjected to green continuous light gave better body weight and FCR as compared to all other treatments. The results of the experiment suggest that we can save both electricity and feed by rearing broilers under continuous green lighting pattern.
