What is the optimum particle size of corn grain for production of pelleted feed of 3mm and 4.5mm pellet size?
And also for mesh feeding to broilers 3 weeks plus age?

Syed Farjad Zaidi The optimum particle size for about 5-8% of the total diet should be about 1200 microns. Include only 3% course ground corn in starter feed to allow birds condition their gut, and then increase this to about 5% in the grower diet, and up to 8% in the finisher diet. This will help the bird condition their gizzard, which is the pace-setter for gut motility and intestinal function.

Syed Farjad Zaidi adding coarse feed particle ia very beneficial for git development,.. in your feed you must have 20-30% particle size >1 mm for stimulating git development.. better using roller Mill than hammer Mill for produce coarse particle size...

Intan Nursiam 20-30% particle size >1 mm ? >1 mm means 5 mm? 8mm? 10mm? 20 mm?

But broiler intestinal organs are much sensitive against coarse ground particles of corn

Asif Obaid what intestinal organs are sensitive? and what do you mean by sensitive? do birds get sick? do birds die? organs stop working?

Khaled Itani the villi are less intect. Intestine will lose integrity with the increased percentage share of coarse corn.

Asif Obaid published papers on this please? Title of paper is enough. Thank you. PS. How much in % is the coarse corn in the diet? How coarse is the corn? What do you mean by “less intect ”??

Khaled Itani this was my own research...in which I replaced graded levels(i.e 0%, 25%,50%, 75% and 100%) of coarse corn with fine corn
i.e. 420 VS 1620 microns... Although the performance remained no significant among all the treatment in Broilers. The differences are in the intestinal health and Pellet durability. The intestinal parenchyma indicates increase is variable lenghts of villi, epithelium is not intact( sluffed off) so surface area is reduced. No goblet cells and demaging effects are increased with the increase in percentage of coarse corn.

Dear Intan
Right you are one can get better uniformity of particle size with roller mill and having proper number of groves in one inch on roller produce best particles. Current day rations are Corn Soya based if Soya is flaked it's good. Particle size in mesh feed is of great importance as Dr Perter Ferket mention the percentages of course particle.
PDI index is that's why important particularly in corn Soya feed as both have low PDI
