摘要：This study was conducted to evaluate the rumen fermentation and milk quality of Friesian Holstein (FH) cows given complete feed silages during lactation. Twelve FH cows in 5th mo lactation were offered four dietary treatments in a completely randomized design with three replications. The treatments were, control diet (NS) containing 50% concentrate, 45% elephant grass and 5% sun flower meal; grass complete feed silage (GS) containing 50% concentrate, 45% elephant grass and 5% sunflower meal; rice straw complete feed silage (RSS) containing 50% concentrate, 30% elephant grass, 15% rice straw and 5% sunflower and palm oil frond complete feed silage (PKS) containing 50% concentrate, 30% elephant grass, 15% palm oil frond, and 5% sunflower meal. Ensilage was done with addition of Lactobacillus plantarum 1A-2 and cellulase enzyme. Analysis of variance and Duncan test were applied to compare the different among the means of treatments. Complete feed silages had range of pH between 3.89-4.44, temperature of 28.0-29.67 oC and lactic acid bacteria of 0.54-1.50 x 108 cfu/g. Crude protein intake of RSS was the highest among treatments. Acetate concentration in rumen liquor was more than 70%. Milk yield and protein were not different among treatments. GS gave the highest milk fat (5.66%). The conclusion was that both complete feed silages, using rice straw or palm oil frond can be used as alternative rations for lactating dairy cows.
其他摘要：Penelitian ini bertujuan untuk mengevaluasi fermentasi rumen dan kualitas susu sapi Friesian Holstein. Dua belas ekor sapi dibagi menjadi empat perlakuan dalam rancangan acak lengkap dengan tiga ulangan. Perlakuan terdiri atas kontrol (NS), yaitu ransum bukan silase yang terdiri atas 50% konsentrat, 45% rumput gajah, 5% bungkil biji matahari; silase komplit rumput (GS) terdiri atas 50% konsentrat, 45% rumput gajah, 5% bungkil biji matahari; silase komplit jerami padi (RSS) terdiri atas 50% konsentrat, 30% rumput gajah, 15% jerami padi, 5% bungkil biji matahari; dan silase pelepah sawit (PKS) terdiri atas 50% konsentrat, 30% rumput gajah, 15% pelepah sawit, 5% bungkil biji matahari. Silase komplit dibuat dengan penambahan bakteri Lactobacillus plantarum 1A-2 0,5 ml/kg dan enzim selulase 1 ml/kg. Data dianalisis menggunakan analisis ragam dan rataan perlakuan yang menunjukkan perbedaan diuji menggunakan uji Duncan. Silase komplit yang dihasilkan berkualitas baik dengan pH 3,89-4,26, suhu 28-29,67 o C, dan total bakteri asam laktat (BAL) 0,54x108 -1,50x108 cfu/g. Sapi yang diberikan RSS memiliki konsumsi protein kasar paling tinggi, konsentrasi asetat cairan rumen lebih dari 70%, dan nyata meningkatkan kadar lemak (5,66%). Kesimpulan kajian ini adalah bahwa silase komplit jerami padi maupun pelepah sawit dapat digunakan sebagai ransum alternatif untuk sapi perah.
