| Layers | Broilers |
| Layers are egg-laying birds, managements for the purpose of getting eggs | Broilers are maintained for getting meat |
| Layers start producing eggs at the age of 20 weeks. so they are kept for layer periods that depends upon laying period | They are raised upto 6-7 weeks in poultry farms and then sent to market to meat production |
| They require enough space and adequate lighting | they require conditions to grow fast and lown mortality |
| They require restricted and calculated feed with vitamins minerals and micronutrients | Their daily food requirments is rich in protein and vitamin-A and K.the fat content also should be adequate |
14.
Need to increase food productivity. This is because:
(i) human population is increasing and demand of food is increasing.
(ii) the present increase in food porduction is not substantial to meet the increasing demand.
(iii) the per capita availability of land is decreasing year after year.
Therefore, there is only way to meet out future food demand is to increase the productivity.
To meet increase productivity and meet future food demand, the possible way is efficient management of both
(i) natural resources such as soil, water and forests
(ii) man made resources such as fertilizers, pesticides and agricultural machinery.
