Ration formulation for laying

Dear Poultry Professionals and Nutritionists,

I´m a student B.V.Sc.&A.H. (9th sem.) at IAAS, Nepal. My family is running a small scale layers farm (Flock Size: 1500+1500+1500=4500) in Nawalparasi District, Nepal where we are manufacturing feed by ourselves. It has really been a challenging task for us to sustain us in this business due to huge production drop during summer months and extreme rise of cost price of Soyabean Meal (Rs. 65 per Kg at present). We would be very much pleased if anyone could let us know the manipulations required to be made in feed formulation during the summer months. Also we have heard about the use of Corn Glutean Meal these days in the big commercial feed industries as a potent feed stuff acting as both energy source as well as protein source which is totally new to our knowledge. Could anyone please tell us what is its nutrient composition? and what is its inclusion levels in different poultry feeds? Below is the formulation of L3 ration for Lohmann and Hi-sex chicken in our farm.

Can anyone please suggest us if there is anything wrong that we need to improve for better egg production and for better chicken health?
