Productive and reproductive performance of golden Montazah and Matrouh chickens as affected by some light colours
Abstract: The aim of the present experiment is to study the effect of strain (Golden Montazah and Matrouh) and light colour (green, white and incandescent) and interaction between them on the performance during the growing and laying periods. At 12 weeks of age, a total of 270 chicks and 45 cockerels (decreased to 27 cockerels at 20 weeks of age) for each strain, were used in the present study. All pullets were individually leg-banded and divided into three groups of each strain. Each group consisted of 90 pullets and 15 cockerels distributed into 3 replicates of 30 pullets and 5 cockerels. The groups of chicks were assigned at random to be reared during experimental period (from 12 to 44 weeks of age) under one of three light colour treatments, being (green or white fluorescent and incandescent).
The obtained results can be summarized as follows:
Rearing period
The Golden Montazah pullets were significantly higher than those of Matrouh ones in live body weight, body weight gain, and feed consumption from 12 to 20 weeks of age. However, the opposite trend was detected for Matrouh strain which showed the higher values of feed conversion ratio from 12 to 20 weeks of age than those of Golden Montazah strain.
The birds exposed to the green light were the best in respect of live body weight, body weight gain and feed conversion ratio. However, the birds exposed to white light consumed obviously the biggest amount of feed at the intervals 12-20 weeks of age followed by those kept under incandescent and green lights in a descending order.
Laying period
The Golden Montazah birds secured significantly higher means than Matrouh ones in live body weight, feed consumption and egg number. However, the opposite trend was recorded for Matrouh strain which showed the higher values of age at different rates of egg production, feed conversion ratio, egg weight, fertility and hatchability at 42 weeks of age.
The birds exposed to the green light recorded the highest values in respect of live body weight, body weight gain age at different rates of egg production, live body weight, feed conversion ratio, egg weight and hatchability. However, the birds exposed to white light were the best in respect of egg number and fertility than other colours. Interactions between strain and light colour in all traits under study were significant at the whole experimental period from 12 to 44 weeks of age.
