R. de  aMaintenance energy requirements of free ranging goats and sheep.  aLogan, Utah: Utah State Universityc1987  a115p.  aTese Doutorado.  aThis study investigated the energy expenditures of goats and sheep under grazing conditions, with the aim of better understanding the amount of energy needed by the free-grazing animals. The Carbon Dioxide Entry Rate Technique (CERT), which was used to estimate the energy expenditures of the free-ranging animals, was later compared with the oxygen consumption method for the same animals under confinement.  aenergy  agrazing  asheep  aEnergia  aNutrição Animal  aOvino  aPastejo  aCaprinos  aOvinos  aRequerimento  aRequirement
