Ishrana jarčeva u toku godine, u periodu mirovanja, odnosno, kada se ne pripuštaju na koze, sastoji se od obroka koji je jednak onome koji dobijaju koze u toku prvog perioda bremenitosti. U sezoni mrkanja, obrok se povećava i sličan je onom koji dobijaju koze u toku druge polovine bremenitosti. U periodu mirovanja, koji obično traje oko 10 meseci, jarčevi se mogu hraniti senom koje može biti i osrednjeg kvaliteta. Količina sena zavisi od njihove telesne mase i obično se kreće od 2 - 3 kg po grlu na dan. Dodavanje koncentrata obrocima, u tom periodu nije potrebno. Ishranu jarčeva treba pojačati na 6-8 nedelja pre početka parenja. U tom periodu cilj ishrane je da se pored obezbeđenja hranljivih materija za spermatogenezu, očuva i kondicija grla. Zbog toga kvalitetu hrane treba posvetiti posebnu pažnju. Ishrana u periodu pripreme grla u samoj sezoni pripusta mora da bude prilagođena kondiciji grla i njihovom opterećenju u priplodu. Smešu koncentrata treba uvesti u ishranu jarčeva na mesec u po dana pre početka parenja, u količini od 400 - 500 g, što u mnogome zavisi od njihove kondicije. Obrocima treba dodavati i mineralne materije, kao i vitamine u vidu premiksa. Takođe, da bi bili sposobni za uspešnu oplodnju koza, jarčevi ne smeju biti iznureni i mršavi kao ni utovljeni tj. gojazni. Ključne reči: ishrana jarčeva, sezona pripusta, hranljive materije.
