How do I formulate my starter and growing mash feed?
From the questions asked - I can make out the guys are new to poultry and small operators. Romulo, John and Nyra, please study the basics of poultry nutrition before venturing into formulations. However for your information, many feed companies sell starter and finisher concentrates, you have to add corn, rice broken, rice bran, wheat or what ever grains available in your area, and make a feed for the broiler chicks, after few batches of chicks, you can start making your own concentrates, the pellet mill, crumblers, conditioners and mixers and grinders, etc., are for big feed mills or operators, not for you, don't waste time on these at the moment, master the art of feeding birds with the simpliest feed, get the efficiency and the required body weights and move forward, it will be the best way.
Initially, the ideal solution for you is to go for the ready made branded feed avaiable in your area. Before buying ascertain the nutritional values of their feed and you can try for feed analysis for safety. Generally most of the branded feed manufacturers do give the nutritional values and they will suggest you what best suits for your farm.
