HUBUNGAN PERIODE LAKTASI DENGAN PRODUKSI SUSU SAPI PERAH PERANAKAN FRIES HOLLAND (PFH) DI BALAI BESAR PELATIHAN PETERNAKAN BATU

2018 
This study aims to determine the relationship between lactation period and milk dairy cattle production with the material used is Fries Holland (PFH) dairy cows as many as 20 heads which are lactation both 12 heads, third lactation 3 heads, and fourth lactation 5 heads. The research method is field survey with the data obtained is to follow and record the amount of milk in milking process every lactation period. With the observed variables is the amount of milk production each lactation period, age, environment, feeding and disease prevention, then the existing data were analyzed using simple linear regression analysis with SPSS program statistic version 17.0. Results of this study the average production of milk dairy cows is highest in the second lactation and decreased in the third and fourth lactation sequentially ie 11.26 liters/head/day, 10.00 liters/head/day and 8.88 liters/head/day. The lactation period (lactation 2-4) had significant effect (P<0,05) with milk production, and low correlation coefficient value between lactation period and milk production was 0,24%. Penelitian ini bertujuan untuk mengetahui hubungan periode laktasi dengan produksi susu sapi perah. Materi yang digunakan adalah sapi perah Peranakan Fries Holland (PFH) sebanyak 20 ekor yang terdiri dari laktasi kedua 12 ekor, laktasi ketiga 3 ekor, dan laktasi keempat 5 ekor. Metode penelitian survei lapang, data diperoleh dengan mengikuti dan mencatat jumlah susu pada proses pemerahan setiap periode laktasi. Variabel yang diamati adalah jumlah produksi susu setiap periode laktasi, umur, lingkungan, pemberian pakan dan pencegahan penyakit. Data dianalisis menggunakan analisis regresi linear sederhana dengan program SPSS statistik versi 17.0. Hasil penelitian menunjukan produksi susu sapi perah paling tinggi terdapat pada laktasi kedua dan menurun pada laktasi ketiga dan keempat secara berurutan yaitu 11,26 liter/ekor/hari, 10,00 liter/ekor/hari dan 8,88 liter/ekor/hari. Periode laktasi (laktasi 2-4) berpengaruh nyata (P<0,05) dengan produksi susu, dan nilai koefisien korelasi 0,24%.
