Sažetak

The objective of this paper was to determine the effect of 5 % and 10% in dry matter (DM) of dehydrated whey (DW) supplemented to alfalfa haylage (AH) (Medicago sativa L.) on the ration ad libitum intake and in vivo digestibility in wether sheep. The results show increase in ad libitum intake of DM (P<0.005) and organic matter (OM) (P<0.05) with DW supplementation but reduced in vivo digestibility of DM (P<0.01), OM (P<0.05) and crude protein (CP) (P<0.001). The level of DW supplementation (5% in comparison with 10%) did not influence AH ad libitum intake (P>0.05) neither in vivo digestibility (P>0.05). It was concluded 5% and 10% of DW supplementation to AH in wether sheep encourages intake of AH but decreases in vivo digestibility probably due to increased rate of the ration passage through the digestive system.
