Research on post-weaning weight gain in domestic camelias reared under two diferent nutritional regimes was conducted at the IVITA camelid research station in Marangani,(Cusco,Pera),withtheobjectiveofdeterminingtheeffectofnutritiononlive weightoffemalealpacasandllamasatoneyearofage.Inthefirstregime,T,,twogroups of30alpacasand30llamaswereeachkeptin2hectaresofcultivatedpastureona7day graze/40dayfallowrotationpattera.
