Penelitian ini bertujuan untuk mengkaji pengaruh pemeliharaan pada kepadatan kandang yang berbeda terhadap performa ayam broiler. Materi yang digunakan dalam  penelitian ini adalah ayam broiler unsexed sejumlah 280 ekor berumur 2 minggu dengan bobot badan 298,37±23,33 gram (CV = 7,81%) yang dipelihara selama 42 hari. Rancangan  percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan. Perlakuan yang digunakan adalah kepadatan kandang dengan T1 = kepadatan kandang 8 ekor/m2, T2  = kepadatan kandang 12 ekor/m2, T3  = kepadatan kandang 16 ekor/m2 dan T4  = kepadatan kandang 20 ekor/m2. Data yang diperoleh dianalisis menggunakan analisis variansi dan uji F pada taraf 5% kemudian dilanjutkan uji wilayah ganda Duncan jika ada pengaruh perlakuan. Hasil penelitian menunjukkan bahwa kepadatan kandang berpengaruh nyata pada konsumsi ransum, pertambahan bobot badan, dan konversi ransum dimana T1 dan T2 dengan kepadatan kandang 8 ekor/m2 dan 12 ekor/m2 lebih tinggi daripada yang lainnya, tetapi jika di hitung dengan satuan luas T4 lebih efisien. Simpulan dari penelitian ini dilihat dari bobot badan per ekor semakin padat semakin rendah tetapi di tinjau dari satuan luas penggunaan kandang per m2 T4 lebih efisien.

Penelitian bertujuan untuk mengkaji pengaruh penggunaan tepung Azolla microphylla fermentasi terhadap performans ayam kampung persilangan. Materi penelitian adalah 80 ekor ayam kampung umur 5 minggu, ayam kampung ini persilangan antara ayam kampung keturunan Bangkok dan Lohman 202 dari peternakan rakyat Temanggung dengan bobot badan 469,80 ± 38 gram (CV = 3,33%). Bahan pakan yang digunakan yaitu jagung, bungkil kedelai, tepung ikan, pollard, bekatul, CaCO3, premix dan tepung azolla fermentasi. Fermentasi azolla menggunakan larutan EM4 dengan perbandingan 3 gram : 10 ml. Perlakuan pakan T0 (ransum basal tanpa tepung azolla fermentasi), T1 (ransum mengandung tepung azolla fermentasi 10%), T2 (ransum mengandung tepung azolla fermentasi 15%) dan T3 (ransum mengandung tepung azolla fermentasi 20%). Kandungan protein pakan 17% dan energi metabolis 2800 kkal/kg. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Parameter yang diamati adalah konsumsi ransum, pertambahan bobot badan dan konversi ransum. Data dianalisis dengan analisis ragam. Hasil penelitian menunjukkan bahwa perlakuan penggunaan tepung azolla terfermentasi berpengaruh nyata (P<0,05) terhadap konsumsi pakan dan pertambahan bobot badan, sedangkan hasil penelitian perlakuan penggunaan azolla terfermentasi tidak berpengaruh nyata (P<0,05) terhadap konversi pakan. Kesimpulan dari penelitian ini adalah pemberian tepung azolla terfermentasi dapat meningkatkan konsumsi pakan dan pertambahan bobot badan pada perlakuan T2, sedangkan untuk konversi pakan pada perlakuan penggunaan tepung azolla terfermentasi menurun.

The aim of this study was to determine the differences of intensive and semi-intensive rearing systems on the performance of female Tegal ducks in feed composition and consumption of nutrients, feed conversion, and egg production. The study was conducted in April -May 2018 at Bulu farmer groups farm in Bulu Village, Pemalang District, Central Java. The material used in the study was 2265 female Tegal ducks from 13 farmers at the KTT Bulusari consisting of 6 semi-intensive breeders and 7 intensive rearing systems. Tegal duck were reared for 40 days. This research was a quantitative descriptive research that interpreted data from research samples, analyzed by the Mann-Whitney test. The results showed that the of feed and HDP of female Tegal ducks that were reared intensively was 7.09 and 57.57%, while the ducks that were kept semi-intensive were 1.43 and 58.84%. Semi-intensive rearing system is more profitable because less feed can produce optimal productivity.

This study was aimed to know the effects of dietary nucleotide on the immune organs performance of broiler chickens raised under different environmental conditions. The material used was unsexed 165 birds broiler chickens 15 days old with an average body weight of 462.20±9 g (CV 3.95%), and nucleotide supplemen. The experiment was completely randomized design with factorial patern 3×3 and 5 repeats. The first factor is three different levels of dietary nucleotide T0=0g/kg, T1=0.5g/kg and T2=1g/kg of feed and the second factor is environmental conditions with S 1 =32±1°C, S 2 =23±1°C and S 3 =24 -34°C. The parameters observed were: relative weight of immune organs that is bursa fabricius, thymus and spleen. Data were analysis of variance to determine the effect of treatment at the level of 5%. It will be followed by Duncan's test if there is real treatment effect. The results showed that there was no interaction of dietary nucleotide with raised under different environmental conditions (P>0.05) and fed dietary nucleotide. Comfortable environment signifficantly (P<0.05) improved relative weight of thymus, however hot environment reduced relative weight of thymus and bursa while enhanced relative weight of spleen. In conclusion, comfortable environment supported performance of immune organs, and hot environment inhibited performance of immune organs.

This study aimed to determine the level of feed consumption, egg production, feed conversion ratio (FCR), and the income over feed cost (IOFC) of layers at CV. Popular Farm, Kendal, Semarang. The study used 100 laying hens aged 40 weeks with average body weight 1,815 ± 0.12 g (CV = 6.65%). Feed compositions used for this research were corn flour, bran, premix, soy, meat bone meal and given additional sinbiotik). Experiments at-designed with a completely randomized design (CRD) with 4 treatments and 5 replications. There were 20 units and each unit consists of 5 laying hens. Giving sinbiotic given as 0%, 0.5%, 1%, and 1.5% in the feed. Sinbiotik gave effect at level of 0.5-1% (P<0.05) to reduce the number of intake and feed conversion ratio. Best treatment combination with the performance of chicken layer with a level of 0.5% with the results better of income over feed cost.
