Abstract

ABSTRAK. Penelitian ini bertujuan untuk menguji kontribusi faktor klimat di musim kemarau terhadap kondisi mikroklimat closed house periode brooder dengan panjang kandang berbeda. Unit kandang digunakan yaitu kandang ukuran panjang 60 m dan 120 m. Pengamatan dilakukan pagi hari (05.00 WIB), siang hari (13.00 WIB) dan malam hari (21.00 WIB). Parameter makroklimat yang diamati meliputi suhu, kelembaban udara, kecepatan angin dan radiasi matahari serta kondisi mikroklimat meliputi suhu, kelembaban udara, kecepatan angin dan THI. Besaran kontribusi diukur berdasarkan keeratan hubungan dengan analisis korelasi. Koefisien korelasi yang menunjukkan hubungan cukup kuat dengan nilai r0,3, digunakan untuk membentuk persamaan regresi. Hasil penelitian menunjukkan besaran kontribusi komponen makroklimat pada pagi hari, siang hari maupun malam hari terhadap kondisi mikroklimat berupa suhu, kecepatan angin dan THI lebih besar di kandang panjang 60 m, sedangkan kontribusi makroklimat terhadap kelembaban udara mikroklimat lebih besar di kandang 120 m (p0,05). Rentang nilai r pada korelasi yaitu cukup kuat hingga sangat kuat. Hasil persamaan regresi yang terbentuk memiliki nilai determinasi R2 sangat kuat, sehingga layak digunakan sebagai prediktor. Prediktor kelembaban udara di kandang 60 m berupa kecepatan angin, kelembaban udara dan radiasi matahari makroklimat, sementara prediktor kelembaban udara di kandang panjang 120 m berupa suhu, kelembaban udara dan radiasi matahari. Simpulan penelitian yaitu kontribusi faktor makroklimat terhadap variasi kondisi mikroklimat berupa suhu, kecepatan angin dan THI pada periode brooder lebih besar di kandang 60 m daripada 120 m, sedangkan kontribusi komponen makroklimat terhadap kelembaban udara di kandang 120 m lebih besar dari kandang 60 m.(Contribution of climatic factor outside the lengths to the change of microclimate closed house with different lengths in brooder period in the dry season)ABSTRACT. This study conducted to calculate macroclimate contribution during brooding period house to different closed house length in dry season. Two broiler closed house 60 m and 120 m length here used in this research. Observed data were daily at 05.00 a.m, 1.00 p.m. and 9.00 p.m to represented microclimate condition in the morning, afternoon and night. Macroclimate parameters observed included temperature, relative humidity, air velocity, sun radiation and microclimate parameters included temperature, relative humidity, air velocity, THI. Macroclimate contribution on the microclimate was calculates based on the strength of the relationship using correlation analysis. Subsequently, regression equation formed on parameters which has r value more than 0.3. Results showed that macroclimate contributes on variation of microclimate condition such as temperature, air velocity and THI which is larger in the 60 m length than 120 m length closed house(p0.05). Macroclimate factors contributes on microclimate humidity which is larger in the 120 m than 60 m closed house length. The range of correlation r value are strong enough to very strong. Regression equations confirmed to having strong determination R value, thus can be used as a predictor of microclimate variation. Predictor parameter of microclimate humidity in 60 m closed house consist of air velocity, relative humidity and sun radiation, whereas microclimate humidity in 120 m closed house predictors consist of temperature, relative humidity and sun radiation. In conclusion macroclimate that contributes to the microclimate variation consist of temperature, air velocity and THI, which is larger in 60 m than 120 m closed house. Meanwhile, macroclimate that contributes to the microclimate humidity is larger in 120 m than 60 m closed house.

Abstract

ABSTRAK. Penelitian ini bertujuan untuk mengkaji pengaruh pemberian pakan dengan sumber protein berbeda terhadap efisiensi penggunaan protein ayam lokal persilangan. Materi penelitian adalah 126 ekor ayam lokal persilangan (unsexed) umur 2 minggu, bobot badan 129,02 6,34 g. Penelitian menggunakan rancangan acak lengkap (RAL), dengan 3 perlakuan, serta 7 ulangan, dan setiap unit percobaan terdiri dari 6 ekor ayam. Perlakuannya antara lain T1: 2 sumber protein (bungkil kedelai, tepung ikan); T2: 3 sumber protein (bungkil kedelai, tepung ikan, MBM (Meat Bone Meal)); T3: 4 sumber protein (bungkil kedelai, tepung ikan, Meat Bone Meal (MBM), Poultry Meat Meal (PMM)). Pakan sumber energi (jagung dan bekatul), pakan sumber mineral CaCo3. Pakan diberikan secara bebas memilih, ad libitum dan dalam benruk mash. Data yang diperoleh dianalisis menggunakan ANOVA (Analysis of Variance) dengan uji F taraf 5%, dan dilanjutkan dengan uji Duncan. Hasil penelitian menunjukkan bahwa pemberian pakan dengan sumber protein berpengaruh nyata (p0,05) meningkatkan konsumsi protein (T1: 7,65c; T2: 9,57b; T3: 11,40a) g/ekor/hari, menurunkan rasio efisiensi protein (T1: 1,65a; T2: 1,42b; T3: 1,40b), dan meningkatkan asupan protein (T1: 5,82c; T2: 7,30b; T3: 8,82a) g/ekor/hari. Disimpulkan bahwa pemberian pakan dengan sumber protein (bungkil kedelai dan tepung ikan) dapat meningkatkan efisiensi protein ayam lokal persilangan.(The influence of different protein source on efficiency protein of crossbred local chicken)ABSTRACT. This research was aimed to determine the influence of different protein source on protein utilization of Crossbred Local Chicken. Using 126 Crossbred Local Chicken unsexed 2 weeks old with the average body weight 129,02 6,34 g. Completely randomized design with 3 treatments and 7 replication applied, each experimental unit consistent of 6 chickens. The treatment are T1: 2 protein source (soybean meal, fish meal); T2: 3 protein source (soybean meal, fish meal, meat bone meal); T3: 4 protein source (soybean meal, fish meal, meat bone meal. poultry meat meal). Feed energy source (corn and rice bran) and mineral source (CaCo3). Feed given with method free choice feeding, ad libitum, mash. The data obtained were analyzed using Analysis of Variance F-test with level 5% and Duncan test. The research showed that different protein source significantly (P0,05), increase protein consumption (T1: 7,65c; T2: 9,57b; T3: 11,40a) g/day, descreased ratio protein efficiency (T1: 1,65a; T2: 1,42b; T3: 1,40b) and increase protein intake (T1: 5,82c; T2: 7,30b; T3: 8,82a) g/day. As a cconclusion that feeding with soybean meal and fish meal as protein source able to improve protein efficiency of crossbred local chicken.

Abstract

Time interval of supplementation of Morinda citrifolia L. by product on the performance broiler chickenABSTRACT. The research using Completely Randomized Design with 3x2 factorial arrangement and 4 replicated. Dose of Morinda citrifolia by product (T) that is 0 g/kg ( T0); 0.50 g/kg ( T1); 0.75 g/kg ( T2) and 1.00 g/kg (T3) as first factor and time interval that is continue (A1) and 1 week interval (A2) as second factor. The performance parameters observed were : feed intake, body weight and small intestine measure. The result showed that no significant effect of time interval and interaction between time interval with Morinda citrifolia by product dose (p0.05) on feed intake and small intestine measure. The addition dose of Morinda citrifolia by product increased (p0.05) body weight, there was interaction (p0.05) between time interval and Morinda citrifolia by product dose on body weight.
