A terra na alimentação de pintos
ResumoThis paper deals with an experiment to determine the optimum period (number of days) in fattening chickens. Thirty chickens R. I. R. were numbered, weighed and feeded in crate, with one standard ration (17% crude protein). The chickens were weighted every two days and the results obtained indicate the optimum is reached between 12 and 16 days of feeding. It was observed that after 16 days the weights stop or decrease progressively as showed by the Grafic I.
