PENGARUH BERBAGAI JENIS BAHAN LITTER TERHADAP KUALITAS LITTER BROILER FASE FINISHER DI CLOSED HOUSE
B.INGGRIS Broiler will breed maximally in an environment with the temperature range between 15 - 28oC. Climate change and extreme temperature lead to the difficulty in setting the appropriate temperature and humidity for broiler breeding. To address such issues, the use of closed house plays an important role. Closed house is a postal system cage that requires litter for its maintenance. The use of various types of litter materials can affect the litter quality including litter moisture content, ammonia levels, pH, and temperature that will ultimately stimulate the productivity of the broiler This study aims to: 1) determine the effect of the use of rice husk, wood shavings, rice straw as litter material on litter quality for broiler during the finisher phase in closed house, 2) determine the best type of litter material on litter quality for broiler during the finisher phase in closed house. The duration of the study was 26 days. The study was started from 15 April to 10 May 2014 in the closed house owned by PT. Rama Jaya Lampung Krawang Sari Village, the District of Natar,Southern Lampung regency. The experimental design for the study was completely randomized design (CRD) with three levels of treatment and six replications. The treatment levels were the types of litter material (i.e. rice husk, wood shavings, chopped straw and rice). The samples were 270 broilers which were divided into 18 plots. Therefore, there were 15 broilers in each plot (per square meter). The data were statistically analyzed using ANOVA with 5% significance level. Duncan test with 5% significance level was conducted for further testing should the ANOVA obtained any significant results. The results showed that(1) the use of rice husk , wood shavings and rice straw as the litter materials in closed house showed a significant effect (P <0.05) on litter moisture content, but not significantly (P> 0.05) on ammonia levels, pH, and litter temperature. (2) The litter materials of rice husk and rice straw in a closed house improved the litter quality. B.INDONESIA Broiler akan berproduksi secara maksimal apabila dipelihara pada lingkungan dengan suhu yang berkisar antara 15--28oC. Seiring dengan perubahan iklim dan cuaca yang ekstrim menyebabkan suhu dan kelembapan sulit untuk disesuaikan dalam pemeliharaan broiler, untuk mensiasati hal tersebut maka diperlukan penggunaan closed house. Closed house merupakan kandang sistem postal yang memerlukan litter dalam pemeliharaan. Penggunaan berbagai jenis bahan litter dapat memengaruhi kualitas litter yang digunakan meliputi kadar air, kadar amonia, pH, dan suhu litter yang akhirnya akan berpengaruh terhadap produktivitas broiler tersebut. Penelitian ini bertujuan untuk : 1) mengetahui pengaruh penggunaan sekam padi, serutan kayu, jerami padi sebagai bahan litter terhadap kualitas litter broiler fase finisher di closed house, 2) mengetahui jenis bahan litter yang terbaik terhadap kualitas litter broiler fase finisher di closed house. Penelitian ini dilaksanakan selama 26 hari yaitu pada 15 April--10 Mei 2014, di closed house milik PT. Rama Jaya Lampung Desa Krawang Sari, Kecamatan Natar, Kabupaten Lampung Selatan. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan dan enam ulangan. Perlakuan terdiri atas jenis bahan litter (sekam padi, serutan kayu, dan cacahan jerami padi). Jumlah broiler yang digunakan sebanyak 270 ekor, dengan jumlah petak sebanyak 18 petak, sehingga setiap petak berisi 15 ekor (per meter persegi). Data yang diperoleh dianalisis ragam secara statistik pada taraf nyata 5%. Apabila pada analisis ragam diperoleh hasil nyata maka akan dilanjutkan dengan uji lanjut menggunakan uji Duncan pada taraf 5%. Hasil penelitian ini menunjukkan : (1) penggunaan jenis bahan litter sekam padi, serutan kayu dan jerami padi pada closed house menghasilkan pengaruh nyata terhadap kadar air litter, tetapi tidak berpengaruh nyata terhadap kadar amonia, pH, dan suhu litter. (2) perlakuan jenis bahan litter sekam padi dan jerami padi pada closed house memberikan pengaruh yang baik terhadap kualitas litter.
