U radu su prikazane razlike u dnevnim prirastima tovljenih kopuna hibridne linije Ross-308 držanih u turnusima A (jesen/zima) i B (proljeće/ljeto). Za vrijeme oba turnusa praćen je utjecaj temperature (u oC) i relativne vlage zrake (u %) na dnevne priraste tovljenih kopuna. Turnus B prelaskom na hranidbu kukuruznom prekrupom pokazuje znatan pad dnevnih prirasta kao i turnus A. Izraženiji pad dnevnih prirasta turnusa B rezultat je visokih dnevnih temperatura, te skraćenja tova za tri tjedna.The paper deals with the differences in daily gains in capon fattening of Ross-308 hybrid line. The capons were raised in groups A (autumn – winter period) and B (spring – summer period). In both groups the influence of air temperature (oC) and relative air humidity (%) on capons daily gains was recorded. In group B, as well as in group A, significant drop in daily gains was evidented when capons were fed with ground corn. A bigger drop of daily gains in group B is a result of high daily air temperatures and two weeks shortage of fattening time
