Enzyme has been used widely in livestock industry in order to improve efficiency on feed utilization (FCR). Indonesian Research Institute for Animal Production has been able to produce enzyme BS4 which has been proven can improve nutrient digestibilities of some feedstuffs and the FCR on improved breed chickens. A research was designed to evaluate the effectivity of the BS4 enzyme on the growing local-KUB chickens. Three dietary treatments, i.e., control diet (C); C + low level BS4; and C + high level BS4 enzyme were fed to KUB chickens from 1 day old to 12 weeks old. Each dietary treatment was fed to 5 replicates x 24 birds per replicate reared on litter cages. Observations were made on body weight at 1 day, 3, 6, 9 and 12 weeks of age, feed intake, FCR and the mortality during the experiment. All data were analysed statistically in order to show the effect of the treatments. Results showed that BS4 enzyme supplementation did not show significant effect on mortality, feed intake and body weight of KUB chickens. However, supplementation of BS4 enzyme improved the FCR overall period of experiment, although it was only statistically significant (P<0.05) for the period of 0-9 weeks of age. It is concluded that supplementation of BS4 enzyme with dose 24 U/kg feed was effective to improve the FCR of the local-KUB chickens.
Pusat Pelatihan Peternakan di Kabupaten Wonosobo dengan Pendekatan Kenyaman Termal adalah wadah/fasilitas yang mengakomodasi para peternak sapi berupa tempat pelatihan sekaligus tempat praktek, untuk memperoleh kemahiran yang berkaitan dengan budidaya, panen, pengolahan susu, dan pengolahan limbah kotoran yang dihasilkan dari sapi perah di Kabupaten Wonosobo dengan mengkondisikan tingkat kenyamanan dan kepuasan pengguna terhadap lingkungan termal yang melibatkan aspek fisik, fisiologis dan psikologis. Pengkondisian lingkungan di dalam bangunan secara arsitektural dapat dilakukan dengan mempertimbangkan perletakan bangunan (orientasi bangunan terhadap matahari dan angin), pemanfaatan elemen-elemen arsitektur dan lansekap serta pemakaian material/bahan bangunan yang sesuai dengan karakter iklimnya.
Sentul-G5 chicken is prepared to be one of the best of pure chicken breed in the local national chicken industry. Therefore, the maximum biological performance information in maintenance with optimum feed supply is needed to know in production efficiency. The aim of this experiment was to determine the effect of levels of dietary protein and energy on the growth and economic efficiency of Sentul-G5 chicken. The experimental design used was a complete randomized design with 6 treatments; R1 (21% CP, 3,000 kcal ME/kg); R2 (21% CP, 2,800 kcal ME/kg); R3 (19% CP, 3,000 kcal ME/kg); R4 (19% CP, 2,800 kcal ME/kg); R5 (17% CP, 3,000 kcal ME/kg); and R6 (17% CP, 2,800 kcal ME/kg). Each treatment was conducted in four replicates, each containing nine days old female chicks. The results showed that Sentul-G5 females up to 15 weeks performed well significantly (P<0.05) when fed diet of R1 (21% CP, 3,000 kcal ME/kg). Key Words: Sentul-G5 Female, Dietary Protein, Dietary Energy ABSTRAKAyam Sentul-G5 dipersiapkan untuk dijadikan salah satu galur unggul murni ayam lokal dalam industri ayam lokal nasional. Oleh karena itu, informasi kinerja biologis maksimum dalam pemeliharaan dengan pasokan pakan optimum perlu diketahui dalam rangka efisiensi produksi. Tujuan dari percobaan ini adalah untuk mengetahui pengaruh berbagai kadar protein dan energi ransum terhadap pertumbuhan dan efisiensi ekonomis ayam Sentul-G5 yang dipelihara sampai umur 15 minggu. Rancangan percobaan yang digunakan adalah rancangan acak lengkap dengan 6 perlakuan; R1 (21% PK, 3.000 kkal ME/kg); R2 (21% PK, 2.800 kkal ME/kg); R3 (19% PK, 3.000 kkal ME/kg); R4 (19% PK, 2.800 kkal ME/kg); R5 (17% PK, 3.000 kkal ME/kg); dan R6 (17% PK, 2.800 kkal ME/kg). Setiap perlakuan dilengkapi dengan empat kelompok ulangan yang masing-masing berisi sembilan ekor anak ayam Sentul-G5 betina umur satu hari. Hasil percobaan menunjukkan bahwa ayam Sentul-G5 betina sampai umur 15 minggu menunjukkan kinerja nyata (P<0,05) terbaik ketika diberi perlakuan pakan R1 (21% PK, 3.000 kkal ME/kg).Kata Kunci: Sentul-G5 Betina, Protein Ransum, Energi Ransum PENDAHULUANAyam Sentul-G5 adalah ayam asli Indonesia berasal dari rumpun Sentul, yang diseleksi untuk pertumbuhan optimum sesuai permintaan pasar, rata-rata bobot hidup 1 kg per ekor umur 10 minggu (Hasnelly et al. 2011). Ayam Sentul-G5 dipersiapkan untuk dijadikan salah satu galur unggul murni ayam lokal dalam industri ayam lokal nasional. Oleh karena itu, informasi kinerja biologis maksimum dalam pemeliharaan dengan pasokan pakan optimum, perlu diketahui dalam rangka efisiensi produksi.Peningkatan produktivitas pada ayam Sentul akan diikuti dengan peningkatan kebutuhan gizinya.
