Daftar Isi:
- Penelitian dilaksanakan pada bulan November 2019 Februari 2020 di Unit Pelaksana Teknis Dinas Balai Pengembangan dan Perbibitan Ternak Domba dan Kambing (UPTD BPPTDK) Margawati, Garut, Jawa Barat. Penelitian bertujuan untuk mengetahui kurva pertambahan bobot badan Domba Garut jantan umur 13-16 bulan yang diberi ransum pada imbangan 40% hijauan dan 60% konsentrat. Domba garut jantan yang digunakan berjumlah 8 ekor yang dipelihara selama 12 minggu. Kurva PBBH dianalisis menggunakan aplikasi Curve Expert, model kurva terbaik ditentukan berdasarkan persamaan regresi yang memiliki koefisien determinasi (R2) terbesar dengan standart error (SE) yang terkecil. Hasil penelitian menghasilkan 3 model kurva dengan nilai R2 yang besar dengan SE yang kecil yaitu Fungsi Rasional (R2 = 0,999; SE = 10,31), Fungsi Eksponensial (R2 = 0,998; SE = 17,91) dan Fungsi Polinomial (R2 = 0,978; SE = 73,54). Model kurva PBBH terbaik diperoleh pada model kurva fungsi rasional karena memiliki R2 yang paling besar dengan SE yang paling kecil.Kata kunci: pertambahan bobot badan harian, domba garut, hijauan, konsentrat Body Weight Growth Curve of Garut Sheep Aged 13-16 Months Feed Ration Containing 40% Grass and 60% ConcentrateABSTRACTThe study was conducted in November 2019-February 2020 in Sheep and Goat Development and Breeding Center, Margawati, Garut, West Java. The study aimed to determine the average daily gain (ADG) curve of male garut sheep aged 13-16 months which were given rations at a balance of 40% forage and 60% concentrate. There are 8 male garut sheep used that are kept for 12 weeks. The ADG curve was analyzed using the Curve Expert application program, the best curve model was determined based on a regression equation that has the largest coefficient of determination (R2) with the smallest standard error (SE). The results of the study produced 3 curve models with large R2 values with small SE, namely Rational Functions (R2 = 0.999; SE = 10.31), Exponential Functions (R2 = 0.998; SE = 17.91) and Polynomial Functions (R2 = 0.978; SE = 73.54). The best ADG curve model is obtained in the rational function curve model because it has the largest R2 with the smallest SE.Keywords: average daily gain (ADG), concentrate, forages, garut sheep
