The objective was to evaluate Heit Chrose (HC) as a feed supplement for dairy cows, which was measured through digestibility, milk production, milk components and body conditions scores. The research was conducted at UPTD Pagerkukuh Wonosobo using 21 dairy cows in late lactation period (12 cows in 2nd lactation and 9 cows in 4th lactation). The diet provided contained 10.1% crude protein and 60.5% total digestible nutrients. The experimental study was conducted with a nested design. The treatments given were R0: control feed + 0 HC, R1: control feed + 1% HC and R2: control feed + 2% HC. The results showed that HC supplementation did not affect feed consumption but increased the dry matter (DM) and organic matter (OM) digestibility. The HC supplement increased milk production in both 2nd and 4th lactations and increased total solid in 2nd lactation. However, the total solid in 4th lactation decreased due to HC supplementation. In other milk components (fat, protein and SNF) HC supplementation created no significant effect. The conclusion of this research is that supplementing HC at the level of 1% in dairy cows feed during late lactation period can increase total solid in 2nd lactations and tend milk production.
