Penelitian ini bertujuan untuk mengevaluasi kinerja itik lokal berdasarkan umur potong sehingga dapat membantu pengembangan itik lokal kedepannya. Pemeliharaan dan pemotongan itik Cihateup, Laboratorium Lapangan Institut Pertanian Bogor (IPB). Data konsumsi pakan, bobot badan, konversi pakan, persentase bobot karkas, persentase daging-tulang-kulit dada dan paha diuji dengan analisis ragam kemudian dilanjutkan dengan uji jarak berganda Duncan menggunakan software SAS versi 9.3 (32) . Hasil penelitian ini menunjukkan bahwa berat dada dan persentase potong payudara terhadap bobot hidup pada umur 4, 8 dan 12 minggu berturut-turut adalah 72,41 ± 1,74 g ekor-1 (14,88 ± 0,27%); 180,89 ± 3,20 g ekor-1 (15,94 ± 0,30%); 286,41 g ekor-1 (18,42 ± 0,32%). Bobot paha dan persentase paha terhadap bobot hidup potong pada umur 4, 8 dan 12 minggu berturut-turut adalah 93,45 ± 3,50 g ekor-1 (19,32 ± 0,55%); 181,12 ± 6,49 g ekor-1 (15,93 ± 0,58%); 249,87 ± 8,51 g ekor-1 (16,08 ± 0,58%). Kesimpulannya persentase dada dan paha itik Cihateup yang dipotong pada umur 4, 8 dan 12 minggu berpengaruh nyata terhadap bobot hidup. (P<0,05). Semakin tua umur potong, persentase dada itik umur 8 dan 12 minggu berpengaruh nyata, tetapi persentase paha itik umur 8 dan 12 minggu tidak berpengaruh nyata.
Corn straw and cob are wastes from corn farming which are not utilized. These corn wastes have potential as an alternative feed for livestock, but have low nutritional quality. Therefore, these corn wastes are fermented to improve its nutritional quality. The purpose of this study was to analyze the effect of corn straw and cob fermentation on the fiber fraction content. This experiment used a completely randomized design with 6 treatments, namely control (elephant grass and grinting grass), corn straw, fermented corn straw, corn cob, and fermented corn cob. Each treatment was repeated 5 times. The variables measured were Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), hemicellulose, cellulose, and lignin. The results showed that the treatment had a very significant effect on the content of NDF, ADF, hemicellulose, cellulose, and lignin. Based on the results of this experiment, it can be concluded that corn cob fermentation can reduce lignin content thus corn cob lignin content can match elephant grass but on the contrary corn straw fermentation cannot be able to reduce lignin content.
This research aimed to determine the alteration of physical characteristics of Muscovy duck hatching egg of natural hatching. The information obtained will be used as a reference to modern hatching (artificially). Muscovy ducks as one of a poultry’s meat producer needs to be improved by population breeding with modern hatching. To be able to artificially incubate the eggs and achieve high hatchability, it is necessary to observe the natural hatching by mother duckling. The observation method was on egg shape index, hygiene of eggshell, shell temperature, egg weight loss, and hatchability. Ten mother ducklings were used during brood time with 15 eggs on each duck. The results showed the eggs that successfully hatched in this research had egg shape index equal 73.6%, egg weight loss 9.6%, eggshell temperature 36.9-38.0ºC, and hatchability 86%. The conclusion of this research during the natural hatching, the eggs undergo physical alteration that were egg weight loss, alteration in the eggshell appearance, and the temperature of the eggshell increased from day one to 28 but decreased at the end of the hatching process.
This study aims to evaluate the age of off-odor detection to ensure more efficient and economical provision of antioxidants in the production of Cihateup ducks. This study used a Completely Randomized Design (CRD) with 3 different treatments of slaughter age, i.e. 4, 8 and 12 week. Each treatment consisted of 6 replications and each replication consisted of 13 ducks. The results showed that the percentage of fat content at the age of 12 weeks was higher than the age of 4 and 8 week. High fat-containing meat tends to undergo fat oxidation. High levels of Fe at 12 week of slaughter age cause high levels of myoglobin in duck meat. Fe2+ is a catalyst in the process of fat oxidation. the brightness value (L) is inversely proportional to the value a of Cihateup duck meat. The darker brightness of the meat causes the flesh to be redder due to myoglobin level in duck meat. The percentage of polyunsaturated fatty acids (ALTJG) is 4- and 12-week slaughter age lower than 8 week of age. The high levels of MDA at 12 week of slaughter age are due to fat oxidation which causes off-odor. Based on the result, the conclusion is that the high fat content, Fe content, color of Cihateup duck meat at 12 weeks of slaughter age caused the percentage of polyunsaturated fatty acids (ALTJG) to be low due to fat oxidation. Fat oxidation caused high levels of MDA in duck meat (12 weeks of slaughter age) resulting in Off-odors in Cihateup duck meat.
Penelitian ini bertujuan untuk menurunkan serat kasar bungkil inti sawit yang sudah difermentasi dengan kapang Neurospora Sithopilla yang mengandung beta karoten dalam ransum untuk meningkatkan kualitas telur puyuh. Pemeliharaan burung puyuh dilaksanakan pada tanggal 09 November 2013 sampai dengan 21 Desember 2013 yang bertempat di kandang percobaan Produksi Ternak Unggas Fakultas Peternakan Universitas Jambi, Mendalo Darat, Jambi. Data yang diperoleh pada penelitian ini dianalisis dengan analisis ragam (ANOVA) sesuai dengan rancangan yang digunakan. Apabila terdapat pengaruh yang nyata maka dilakukan uji jarak berganda Duncan (Steel dan Torrie, 1991). Penelitian ini dilaksanakan dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan 5 ulangan, setiap unit terdiri dari 5 ekor puyuh. Hasil penelitian ini menunjukkan bahwa penggunaan BISF sampai taraf 30% dalam ransum berbeda tidak nyata (P>0,05) terhadap berat telur, tebal kerabang telur dan haugh unit telur puyuh. Hasil penelitian bahwa penggunaan BISF sampai taraf 30% dalam ransum berbeda nyata (P<0,05) meningkatkan warna kuning telur dan indeks kuning telur. Hasil penelitian ini dapat disimpulkan bahwa penggunaan Bungkil Inti Sawit Fermentasi (BISF) dalam ransum puyuh petelur sampai taraf 30% dapat meningkatkan kualitas telur puyuh pada warna dan indeks kuning telur.
