摘要：Background and Objective: Fibre feed is the basis of dairy cattle ration and its quality is directly related to the quality of milk, primarily milk fatty acids. The feeds quality varies between locations. This study compared fibre feed quality between the dairy cattle area and its impacts on milk production and quality. Materials and Methods: Five main fibre feed (Napier grass, natural grass, rice straw, corn stover and corn husk) from 4 dairy farm areas in West Java (Pangalengan, Lembang, Cibungbulang and Sukaraja) were evaluated on their effect on milk production and quality. Parameters observed were proximate composition, cell wall fractions, in vitro digestibility, Relative Forage Value (RFV), milk produced, milk component and milk fatty acids. The correlation between fibre feed and milk quality was investigated. Results: It was found an interaction between treatments on ash, crude protein, ether extract, silica, lignin and neutral detergent fibre digestibility parameters. Napier grass has the highest quality. The Pangalengan feeds have the highest RFV. Milk from Bogor has the best quality, high unsaturated fatty acids, conjugated linoleic acids, Hypocholesterolemic/Hypercholesterolemic (HH) ratio. Correlation analysis between feed and milk quality showed that milk production and quality are influenced positively by RFV and digestibility but negatively by CF, NDF and ADF. Conclusion: This study concluded that dietary fibre feed quality could not directly determine milk fatty acids composition.
