Abstract

Survey perunggasan ayam ras pedaging di tingkat peternak plasma telah dilakukan di dua kabupaten, yaitu Subang dan Ciamis yang masing-masing sistem management usahanya memiliki pola khas. Pelaksanaan kemitraan pengadaan sarana produksi ditangani oleh Pengusaha Pengelola sebagai pihak inti melalui kontrak kerjasama upah bagi hasil bagi peternak plasma. Lama pemeliharaan ayam broiler di Kabupaten Subang terdiri atas dua kategori; pertama 28 – 32 hari dan kedua 32 – 42 hari, sedangkan di Kabupaten Ciamis 32 – 42 hari. Rataan pendapatan per ekor di Kabupaten Subang Rp 100,45 dan di Ciamis Rp 112,55. Dari hasil penelitian dapat disimpulkan dua macam pola pengembangan, yaitu : di Kabupaten Ciamis berbentuk pola entrepreneur, sedangkan di Kabupaten Subang pola manajer. Penetapan formula harga ditentukan oleh faktor input utama, output di tingkat pasar lokal dan konversi ransum dengan penerapan asumsi : Harga ayam potong di pasar ≥ 2,7 harga ransum + 1,5 harga anak ayam umur sehari adalah paling tepat untuk peternak plasma. Kata Kunci : Pola pengembangan usaha, perunggasan.

Abstract

The purpose of this experiment was to study the optimal of dietary protein level of medium type layer in growing period associated with the growth of reproductive organ and the effect on laying performance. The experiment used 480 pullets of 10 weeks old grouped into three treatments of three protein levels, 12, 15 and 18. In laying period all of the treatments used the same ration with 15% protein. The results showed that dietary protein level in growing period significantly affected the growth of reproduction organ, growth performance and eggs quality. Effects of treatment in laying period was significantly different on laying performance only in early laying period, and subsequent period was not differently different. The conclusion of this experiment was the level of 12% adequate for minimal growth, level of 15% adequate for optimal growth and level 18% showed better performances during laying period. The results suggest that in growing period the dietary protein level is not below 15%.     Key Words: Protein, Reproduction Organ, Laying Performance
