Penelitian ini bertujuan untuk mengidentifikasi hubungan antara biokimia darah dengan kinerja reproduksi kambing Saanen di Balai Besar Pembibitan Ternak Unggul dan Hijauan Pakan Ternak Baturraden (BBPTU-HPT Baturraden). Penelitian ini dilaksanakan pada bulan Maret sampai dengan April 2017. Lima belas ekor kambing Saanen betina dalam kondisi laktasi ke-2 digunakan dalam penelitian ini. Indikator kinerja reproduksi didasarkan pada post partum estrous (PPE), service per conception (S/C), dan days open (DO). Sampel darah diambil tiga kali selama dua siklus estrus, kemudian dianalisis biokimia darahnya meliputi total protein, kolesterol dan blood urea nitrogen (BUN) di Laboratorium Penelitian dan Pengembangan Terpadu Universitas Gadjah Mada. Sampel darah diambil melalui vena jugularis sebanyak 3 mL sebelum pemberian pakan. Data kinerja reproduksi dan biokimia darah yang diperoleh dianalisis menggunakan model korelasi. Identifikasi fase estrus menggunakan metode vaginal smear. Pengamatan sel epitel vagina dilakukan di Laboratorium Fisiologi dan Reproduksi Ternak Fakultas Peternakan Universitas Gadjah Mada. Hasil penelitian menunjukkan 71,11% ternak berada pada fase proestrus. Rata-rata PPE, S/C dan DO berturut-turut 155,60���±14,60 hari; 2,73���±0,70 kali; dan 186,80���±23,60 hari. Rata-rata total protein darah, kolesterol dan BUN berturut-turut 6,71���±1,59 g/dL; 79,81���±20,73 mg/dL; dan 46,75���±9,82 mg/dL. Terdapat korelasi signifikan antara blood urea nitrogen dan post partum estrous (p<0,05) dengan koofisien korelasi -0,301. Variabel biokimia darah yang lain tidak memiliki korelasi signifikan (p>0,05) dengan kinerja reproduksi kambing Saanen. Kesimpulan dari penelitian ini adalah terdapat korelasi lemah dan bernilai negatif sebesar 9% antara blood urea nitrogen dengan post partum estrous.

This study was aimed to identify the relationship between blood biochemical with reproductive performance of Saanen goats in Balai Besar Pembibitan Ternak Unggul dan Hijauan Pakan Ternak Baturraden (BBPTU-HPT Baturraden). This research was conducted in March to April 2017. Fifteen female Saanen goats on 2nd lactation were used in this research. Reproductive performance was measured based on post partum estrous (PPE), service per conception (S/C), and days open (DO). Blood samples were collected three times during two estrous cycles, then analyzed for total protein, cholesterol and blood urea nitrogen (BUN) in the Integrated Research and Development Laboratory Universitas Gadjah Mada. Blood samples were taken through the jugular vein as much as 3 mL before fed. The data of reproductive performance and blood biochemical were analyzed using correlation model. Vaginal smear method used to identify the estrous cycle. The observation of vaginal epithelial cells was done in the Laboratory of Animal Physiology and Reproduction Faculty of Animal Science Universitas Gadjah Mada. The results showed that 66.67% of livestock was in the proestrus phase. The average value of PPE, S/C and DO were 147.66���±11.90 days; 2.33���±0.50 times; and 171.67���±12.08 days. The average value of total protein, cholesterol and BUN were 6.80���±0.99 g/dL; 79.50���±18.36mg/dL; and 48.14���±6.56mg/dL. There was significant correlation between blood urea nitrogen and post partum estrous (p<0.05), with significant correlation -0.301. There were no significant correlation between the other blood biochemical variables (p>0.05) to the reproductive performance of Saanen goats. The conclusion of this research, there was 9% of weak and negative correlation between blood urea nitrogen with post partum estrous.
