Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi 3% susu bubuk afkir terhadap produksi dan komposisi susu sapi perah Peranakan Friesian Holstein (PFH) awal laktasi. Delapan ekor sapi perah PFH awal laktasi dibagi menjadi dua kelompok sehingga tiap kelompok terdiri dari empat ekor, yaitu kelompok kontrol dan kelompok perlakuan. Pakan yang diberikan adalah hijauan dan konsentrat dengan perbandingan 60 : 40. Kelompok kontrol mendapatkan konsentrat dengan kandungan BK 80,00%, PK 11,52% dan TDN 68,08%, sedangkan kelompok perlakuan mendapatkan konsentrat dengan kandungan BK 82,90%, PK 15,52% dan TDN 73,53%. Air minum diberikan secara ad libitum. Data konsumsi nutrien, produksi dan komposisi susu yang diperoleh dianalisis dengan Uji Independent Sample T-test. Hasil penelitian menunjukkan bahwa produksi susu (16,01 ± 2,43 vs. 20,92 ± 5,16 L/ekor/hari), produksi 4% FCM (16,39 ± 2,70 vs. 21,46 ± 5,53 kg/ekor/hari), kadar lemak (3,96 ± 0,25 vs. 3,97 ± 0,19%), kadar protein (3,18 ± 0,09 vs. 3,25 ± 0,17%), kadar laktosa (4,18 ± 0,12 vs. 4,17 ± 0,12%), kadar solid non fat (7,56 ± 0,21 vs. 7,66 ± 0,27%) dan kadar total solid (11,50 ± 0,42 vs. 11,63 ± 0,17%) antara kelompok ko ntrol dan perlakuan tidak menunjukkan pengaruh yang nyata terhadap pemberian suplementasi 3% susu bubuk afkir pada sapi perah awal laktasi. Pemberian suplementasi 3% susu bubuk afkir dengan kandungan protein dan energi yang lebih tinggi pada sapi perah Peranakan Friesian Holstein awal laktasi tidak berpengaruh nyata terhadap produksi dan komposisi susu, walaupun demikian pada kelompok perlakuan ada tendensi kenaikan pada parameter yang diukur. [This study was conducted to determine the effect of supplementation 3% outdated milk powder to milk production and composition of early lactation Friesian Holstein Crossbred (PFH). Eight early lactation Friesian Holstein Crossbred (PFH) cows were divided into two groups. Four animal s were used as a control group and another group as treatment object. The feed for cattle is forages and concentrates with a ratio of 60 : 40. The control group getting concentrate containing dry matter (DM) 80.00%, crude protein (CP) 11.52% and total digestible nutrien (TDN) 68.08%, while the treatment group getting concentrate containing dry matter (DM) 82.90%, crude protein (CP) 15.52% and total digestible nutrien (TDN) 73.53%. Water was given by ad libitum. Data nutrient consumption, milk production and composition were tested using T-test analysis. Result showed that milk production (16.01 ± 2.43 vs. 20.92 ± 5.16 L/head/day), 4% FCM (16.39 ± 2.70 vs. 21.46 ± 5.53 kg/head/day), fat content (3.96 ± 0.25 vs. 3.97 ± 0.19%), protein content (3.18 ± 0.09 vs. 3.25 ± 0.17%), lactose content (4.18 ± 0.12 vs. 4.17 ± 0.12%), solid non fat content (7.56 ± 0.21 vs. 7.66 ± 0.27%) and total solid content (11.50 ± 0.42 vs. 11.63 ± 0.17%) between control and treatment were not significant to supplementation 3% outdated milk powder on early lactation dairy cattle. Supplementation 3% outdated milk powder with high protein and energy content on early lactation Friesian Holstein Crossbred are not significant on milk production and composition, although the treatment group there are a tendency to increase in the measured parameter.]
