Judul: Correlation Between Somatic Cell Count and Composition of Sapera Goat Milk
Abstrak: Kualitas dari susu kambing dapat dipengaruhi oleh jumlah sel somatik (JSS). Penelitian bertujuan mengetahui pengaruh JSS terhadap komposisi susu kambing Sapera yang dibudidayakan di Balai Penelitian Ternak Ciawi Bogor. Sampel susu diambil dari delapan ekor kambing Sapera setiap pekan selama tiga pekan. Pemeriksaan dilakukan untuk mengetahui kandungan lemak, berat jenis (BJ), laktosa, protein dan bahan kering tanpa lemak (BKTL) menggunakan milk analyzer, sedangkan pada parameter bahan kering (BK) dilakukan akumulasi jumlah lemak dengan BKTL serta menghitung JSS dengan metode Breed. Data sampel yang didapat, dibagi menjadi 2 kelompok yakni sampel dengan JSS ≤ 1 x 106 sel/ml (kelompok JSS rendah) dan ≥ 1 x 106 sel/ml (kelompok JSS tinggi). Selanjutnya, komposisi antar dua kelompok yang didapat dianalisis menggunakan T-test serta dilakukan analisis korelasi Pearson antara JSS dengan komposisi susu. Hasil menunjukkan perbedaan sangat nyata pada lemak, BJ, laktosa, protein, BKTL dan BK antara kelompok JSS tinggi dan kelompok JSS rendah (P<0,01), sedangkan pada hasil korelasi memperlihatkan JSS memiliki korelasi positif terhadap lemak dan BK serta berkorelasi negatif dengan BJ, laktosa, protein dan BKTL. JSS tinggi menyebabkan penurunan sintesis laktosa dan proteolisis, sehingga menurunkan angka BJ, prosentase kadar protein, laktosa, BKTL dan menaikkan prosentase kadar lemak dan BK., Goat milk quality could be affected by somatic cell count (SCC). Purpose of study was to determine the affect of SCC toward the composition of Sapera goat’s milk which bred in Balai Penelitian Ternak Ciawi Bogor. Samples were taken from eight Sapera goats once every week for three weeks. The SCC calculation used Breed method and milk analyzer was used to examine and determine Sapera goat milk’s fat content, density, lactose, protein and solid non-fat (SNF). Fat and SNF was adding up to count total solid parameter. Data samples then divided in two groups which are sample SCC ≤ 1 x 106 cell/ml (low SCC group) and ≥ 1 x 106 cell/ml (high SCC group). Based on the obtained data, composition between two groups has been analyzed using T-test and correlation between SCC and milk content also has been analyzed using Pearson correlation. Result showed that there was significant distinction between fat, density, lactose, protein, SNF and solid in low SCC group and high SCC group (P<0,01), as the correlation result showed that SCC obtained positive correlation toward fat and solid but had negative correlation toward density, lactose, protein and SNF. High SCC content could reducing lactose synthesis and proteolisis as it reducing density, percentage of protein, lactose, and SNF, also increasing percentage of fat and solid.

Judul: Kualitas Susu Segar sebagai Bahan Baku Keju Ditinjau dari Jumlah Sel Somatis, Kadar Lemak, dan Kadar Protein
Abstrak: The aim of this study was to observed quality of fresh milk reviewed by somatic cells count, fat and protein levels. This research was conducted in February 2011 to July 2012. There were 35 bulk milk were taken from six farms. Data were analyzed descriptively and using linear correlation. The highest number of somatic cell, fat, and protein 2 780 000.00 ± 1 146 423.01 cell/ml, 4.05 ± 0.34%, and 3.66 ± 0.28% respectively. The result showed that positive correlation between bulk milk somatic cells count with fat and protein levels from dairy farmers which suppliers of cheese industry.
