Utjecaj dodatka sirutke sjenaži lucerne na sadržaj masnih kiselina u buragu kastriranih ovnova
View through CrossRef
Cilj istraživanja bio je utvrditi utjecaj dodatka sirutke u prahu sjenaži lucerne (SL) na udio masnih kiselina u buragu kastriranih ovnova. U istraživanju su korištena 3 hranidbena tretmana: (i) 100% SL; (ii) sjenaža lucerne uz dodatak 5 g sirutke kg-1 tjelesne mase kastriranih ovnova (SL5) i (iii) sjenaža lucerne uz dodatak 10 g sirutke kg-1 tjelesne mase kastriranih ovnova (SL10). Dodatak sirutke u prahu SL smanjio je udio octene kiseline u buragu kastriranih ovnova (P<0,001), te povećao udio propionske (P<0,001) i mliječne kiseline (P<0,001). Kod tretmana SL5 i SL10 je utvrđen viši udio (P<0,01) izomaslačne kiseline u usporedbi s tretmanom SL. Kod tretmana SL10 je utvrđen viši udio izovalerijanske kiseline u usporedbi s tretmanom SL i SL5 (P<0,001). Zaključeno je da dodatak sirutke u prahu obroku baziranom na sjenaži lucerne smanjuje udio octene kiseline, a povećava udio propionske i maslačne kiseline u buragu kastriranih ovnova.
