Pengaruh Dry Period dan Days Open Terhadap Produksi Susu Sapi Friesian Holstein (FH) Di BBPTU-HPT Baturraden. Tujuan dari penelitian ini yaitu mengetahui rataan dan simpang baku, serta pengaruh dari dry period dan days open terhadap produksi susu sapi FH di BBPTU-HPT Baturraden. Metode analisis data yaitu dengan korelasi dan regresi linier. Data diperoleh dari data primer dan data sekunder. Data primer diperoleh dari sapi sebanyak 50 ekor yang mempunyai catatan produksi dan reproduksi setiap individu sapi laktasi ke dua, yang meliputi produksi susu mingguan, tanggal lahir, beranak, inseminasi yang menghasilkan kebuntingan, dan tanggal kering kandang dari setiap ekor induk sapi. Data sekunder diperoleh dari hasil wawancara. Hasil penelitian menunjukan rataan dan simpang baku dry period 90,420±27,98 hari, days open 165,22±51,08 hari, poduksi susu laktasi kedua terkoreksi 3.760,76±1.163,67 l. Hasil analisis diperoleh koefisien korelasi dry period sebesar 0.197 dan days open sebesar 0.315, dengan nilai koefisien determinasi (r²) dry period = 3,9% dan days open = 9,91%. Persamaan regresi linier dry period  Y  = 3018,5 + 8,2094X dan days open diperoleh persamaan Y = 2575,8 + 7,1723X. Berdasarkan hasil penelitian dapat disimpulkan bahwa nilai koefisien korelasi menunjukan bahwa dry period dan days open memiliki hubungan positif yang rendah terhadap produksi susu. Semakin panjang days open maka dapat mempengaruhi produksi susu yang relatif semakin tingggi.

Effect of Dry Periods and Open Days on the Production of Friesian Holstein Milk (FH) at BBPTU-HPT Baturraden. The purpose of this study is to find out the standard and standard intersections, as well as the effect of dry period and days open on FH cow milk production in Baturraden BBPTU-HPT. Data analysis methods are correlation and linear regression. Data is obtained from primary data and secondary data. The primary data was obtained from cattle as many as 50 individuals who had the second production and reproduction record of each individual lactating cow, which included weekly milk production, date of birth, breeding, insemination that resulted in pregnancy, and dry date of the cage from each cows. Secondary data obtained from interviews. The results showed that the mean and dry period standard intersections were 90.420 ± 27.98 days, days open 165.22 ± 51.08 days, second lactation milk production was corrected 3,760.76 ± 1,163.67 l. The results of the analysis obtained dry period correlation coefficient of 0.197 and days open of 0.315, with the dry period r² determination coefficient = 3.9% and days open r² = 9.91%. Dry period linear regression equation Y = 3018,5 + 8,2094X and days open obtained the equation Y = 2575,8 + 7,1723X. Based on the results of the study it can be concluded that the correlation coefficient shows that dry period and days open have a low positive relationship to milk production. The longer days open can affect milk production which is relatively higher.
