Abstract (croatian)
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.
Abstract (english)
The objective of this study was to determine the effect of dry whey supplementation to alfalfa haylage (AH) on fatty acids concentration in the rumen of whether sheep. Total of 3 feeding treatments were used in the study: (i) 100% AH; (ii) AH supplemeneted with of 5 g whey kg-1 body weight of wether sheep (AH5) and (iii) AH supplemeneted with 10 g whey kg-1 body weight of wether sheep (AH10). The supplementation of whey to AH reduced the proportion of acetic acid in the rumen of wether sheep (P<0.001), and increased the proportion of propionic (P<0.001) and butyric acid (P<0.001). In the AH5 and AH10 treatments, a higher proportion (P<0.01) of isobutyric acid was found compared to the AH treatment. A higher proportion of isovaleric acid was determined in the AH10 treatment compared to the AH and AH5 treatment (P<0.001). It was concluded that the supplementation of whey to alfalfa haylage reduces the proportion of acetic acid and increases the proportion of propionic and butyric acid in the rumen of wether sheep.
