Karisma, Widi Putri and Prof. Dr.I r. Sucik Maylinda,, MS. (2023) Hubungan Statistik Vital Dengan Volume Ambing, Produksi Dan Kualitas Susu Sapi Perah Holstein Indonesia Di Peternakan Rakyat Kecamatan Pujon, Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Sapi perah Holstein Indonesia merupakan salah satu komoditi ternak ruminansia besar yang menghasilkan produk utama berupa susu dengan kandungan nutrisi tinggi. Penelitian ini dilaksanakan pada tanggal 18 Agustus – 20 September 2022 di Peternakan Rakyat Wilayah Kecamatan Pujon, Kabupaten Malang. Tujuan penelitian untuk mengetahui hubungan antara statistik vital dengan volume ambing, produksi dan kualitas susu sapi perah Holstein Indonesia. Materi yang digunakan sapi perah Holstein Indonesia betina dewasa laktasi sebanyak 30 ekor dengan periode laktasi 1 dan 2 dan umur 2-5 tahun. Metode penelitian yang digunakan adalah studi kasus melalui pengamatan langsung dan wawancara. Pengambilan sampel secara purposive sampling yaitu pengambilan sampel ditentukan oleh peneliti berdasarkan pertimbangan tertentu. Karakteristik sampel yang digunakan yaitu sapi perah Holstein Indonesia betina dewasa, sehat, sedang laktasi, periode laktasi 1 dan 2 serta umur 2-5 tahun. Analisis data koefisien korelasi, koefisien determinasi dan regresi linier menggunakan Microsoft Office Excel 2020. vii Hasil penelitian menunjukkan bahwa rata-rata nilai statistik vital di lokasi penelitian yaitu lingkar dada 185,1 ± 10,03 cm, panjang badan 152,7 ± 9,79 cm dan tinggi badan 136,6 ± 5,88 cm. Nilai tersebut lebih tinggi dari standar minimum menurut SNI (2012) yaitu lingkar dada 155 cm, panjang badan 123 cm dan tinggi badan 115 cm. Rata-rata nilai produksi susu 12,783 ± 3.42 liter. Hasil sesuai dengan standar produksi susu sapi perah Holstein Indonesia yaitu 10 liter per hari per masa laktasi (Haloho, dkk., 2021). Rata-rata nilai dari uji Lactoscan kualitas susu sapi yaitu berat jenis 1,03 ± 0.00 g/ml, kadar lemak 4,73 ± 1,18 %, Solid Non Fat 9,21 ± 0,53 % dan kadar protein 3,38 ± 0,19 %. Nilai yang diperoleh lebih tinggi dari standar minimum menurut SNI (2011) mengenai syarat mutu susu sapi segar yaitu berat jenis 1,0270 g/ml, kadar lemak 3%, kadar SNF 7,8% dan kadar protein 2,8%
English Abstract
The research was conducted at the Pujon Subdistrict, Malang Regency, to determine the relationship between vital statistics with udder volume, milk production and the quality of Indonesian Holstein dairy cows. The material used was 30 adult female Indonesian Holstein dairy cows who were lactating with the 1st and 2nd lactation periods and were 2-5 years old. The variables were vital statistics (chest circumference, body length and body heigh), milk production and quality (specific gravity, fat content, solid nonfat and protein content). Sampling was done by purposive sampling and data analysis using correlation coefficient analysis Microsoft Office Excel 2020. The results showed that the average of vital statistics was chest circumference 185.1 ± 10.03 cm, body length 152 .7 ± 9.79 cm and body heigh 136.6 ± 5.88 cm. The average of milk production was 12.783 ± 3.42 liters. The average milk quality was specific gravity 1.03 ± v 0.00 g/ml, fat content 4.73 ± 1.18 %, Solid Non-Fat 9.21 ± 0.53 % and protein content 3.38 ± 0.19 %. The results showed that there was a relationship between body length and udder volume in Indonesian Holstein dairy cows at the study site (p<0.05), while chest circumference and height did not have a relationship with udder volume. The results also showed no significant correlation between vital statistics on milk production and the quality of Indonesia Holstein dairy cows at the study site (p>0.05). The study concluded that every 1 cm increase in body length could increase udder volume by 1.5646 liters so that body length could be used to estimate udder volume.
