The poultry sector can enhance production of eggs and chicks from quail parent flocks through effective lysine phase feeding system, besides reducing dietary costs.

These were the findings of a recent research conducted in the department of poultry production at Avian Research and Training Center UVAS by an M.Phil researcher Abdul Samad Haidary under the supervision of a renowned team of scientists including Dr Muhammad Akram, Khalid Javed, Abdul Waheed Sahota and Jibran Hussain.

Abdul Samad Haidary told The Nation that researchers of department of Poultry Production has conducted a research to evaluate the egg production of four different close-bred stocks of Japanese quail supplemented with different lysine levels during first four weeks of life. The group-A was provided the diet containing 1.3% lysine throughout the grow-out period of 28 days, while the group-B with 1.4% lysine up to the age of 14 days and then 1.2% up to the age of 28 days. The group-C was split into three phases; i.e. 0- 9. 10 -19 and 20-28 days which were supplemented with 1.5, 1.3 and 1.1% lysine respectively.

The researcher said that he and his team found that among different strains of Japanese quails, major showed better weight gain, egg production, feed conversion ratio-FCR/12 eggs and FCR/g egg mass, giving rise to more profit margin for quails breeder farmer.  Fertility and Hatchability was higher in flocks reared under group-B (1.4% lysine for the age of 14 days and then 1.2% last 14 days, up to the age of 28 days).

It is hoped that this research would bring a great revolution in the poultry industry. By adopting this research, farmers would be able to cut down the cost of production of broiler by achieving more number of chicks and maximum weight gain with less feed intake resulting into better feed conversion ratio. Hence this would help the farmer to offer high quality protein at a cheaper price.

Abdul Samad Haidary said that his research had even exercised good effect on the egg quality traits which gave the better health status to the bird which would ultimately produce better higher albumen height, yolk height, yolk index, Haugh unit score, yolk weight, shell weight and albumen pH which ultimately improves quality of eggs for consumers. It has been observed that maximum albumen weight was observed in phase 2.

Phase feeding can be an effective measure to reduce dietary costs without losing performance and can be resulted into more number of chicks which ultimately increase the profit as compared to single-phase feeding for all grow-up period.
