Processing grains for feed is aimed at getting the easiest digestible grains to maximize starch availability, thus increasing the energy supply. [22] Hutjens (1999) reported that milk performance was significantly better when the cattle were fed with ground corn. A study compared the digestibility of various corn particle sizes and distribution ...
Chickens could be sent to slaughterhouses for butchering and processing into prepackaged commercial products to be frozen or shipped fresh to markets or wholesalers. Meat-type chickens currently grow to market weight in six to seven weeks whereas only fifty years ago it took three times as long. [ 20 ]
