Doe Productivity Index of Saburai Goats at Sumberejo and Gisting Districts, Tanggamus Regency

Saburai goat is a local genetic resource of Lampung Province. Sumberejo and Gisting district are Saburai goat development area. To increase the productivity of Saburai goats in both districts, selection on doe was done based on doe productivity index (DPI).The study was conducted from July 1st, 2017 to October 30th, 2017 to estimate the productivity of Saburai goats based on DPI. Materials of this research were a recording of mating, birth, and weaning weight of 50 of Saburai goat kids, kept in Sumberejo and Gisting district. The Does were in second parity and had weaned the goat kids. Variables observed were litter size (LS), kidding interval (KI), weaning weight (WW) and DPI. The Result indicated that in Sumberejo LS, KI, WW and DPI were 1.74±0.44 heads, 22.00±0.95 months, 21.48±4.04 kg, and 57.52±8.15 kg, respectively. While in Gisting LS, KI, WW, and DPI were 1.44±0.50 heads, 7.86±0.35 months, 15.18±4.32 kg, and 21.02±4.86 kg, respectively. It could be concluded that Saburai doe in Sumberejo district could be selected for breeding stock.

Model Kurva Pertumbuhan Pra Sapih Kambing Saburai di Kabupaten Tanggamus

Kurva pertumbuhan merupakan gambaran kemampuan individu untuk menampilkan potensi genetik dan perkembangan tubuh mencapai dewasa. Penelitian mengenai model kurva pertumbuhan kambing Saburai sejak lahir sampai umur 3 bulan telah dilaksanakan di wilayah sumber bibit Kabupaten Tanggamus. Tujuan penelitian ini adalah untuk mengetahui model kurva pertumbuhan kambing Saburai pada periode pra sapih. Penelitian ini menggunakan metode observasi dengan sample acak sebanyak 145 ekor kambing. Data yang diperoleh dianalisis regresi. Hasil analisis menunjukkan bahwa model kurva pertumbuhan kambing Saburai dari lahir sampai 3 bulan mengikuti model persamaan regresi Y=0,16x + 3,29 untuk anak kambing saburai jantan dan Y=0,149x + 3,25 untuk betina.
