Effect of different colours of light on survivability and performance of the helmeted guinea fowl keets
Abstract
A total of four hundred and fourteen-2-weeks old guinea fowl keets raised in the humid tropical environment were used to evaluate the performance of guinea fowl reared under 6 (six) different colours of light. The experimental design was a complete randomized design and each of the treatment groups were replicated thrice. The birds (keets) were subjected to a starter diet formulated to contain 12.05 MJ/Kg ME and 21% CP and were allotted to treatments of Green, Blue, White, Red, Yellow and Black lights. Each colour of light was provided with a 60 watts bulb placed in a room to provide temperature of 270C-300C and was monitored with a thermometer hung at the middle if the pens and read 3 times each day. At the end of 7 weeks, daily feed intake, daily body weight gain, daily water intake and mortality were recorded while feed conversion ratio was calculated. There were no significant differences (P>0.05) among the treatment means in the final body weight, daily weight gain and feed conversion ratio. But the birds showed significant differences (P<0.05) in their feed intake, water intake and mortality. Birds reared under yellow light gave the best value (3.25g) as per the daily weight gain, while those reared under yellow light gave the least value (2.46g) with feed conversion ratio ranging from 4.62-5.84, showing no significant difference of (13.98) was obtained among treatments when daily feed intake was considered. Birds reared under green, blue, white, red and yellow (13.04 – 13.98) were comparable while those reared under black light (14.45g) showed significant difference. In conclusion, green produced low value of 1.45% better than other colours viz11.59, 7.25 and 4.435.
