Pengaruh Taraf Penyemprotan Air dan Lama Penyimpanan Terhadap Daya Tahan Ransum Broiler Finisher Berbentuk Pellet

Abstract

The storage is very important in a farm management, because this activity can take care of feed stability which enough and preferable to be consumed by animal and also strive for animal food availability continuously. The purpose of this research is to know the water spraying level and variation of storage period against the endurance of pellet broiler finisher ration. This research was designed by a Completely Randomized Design Factorial with two factors (water spraying different level and storage period) with four replicates, the significant result were analyzed by orthogonal contras test. On this experiment, the different level of water spraying (0, 3, 6%) were conducted during mixing at conditioning process, and then the ration were stored until four weeks to study the endurance of pellet e.g.: water content (%), water activity, specific gravity (ton/m 3 ), pellet durability index (%), attack of insect. The water content, specific gravity, and pellet durability index was very significantly (P<0.01) reduce by water spraying different level, and not significantly on water activity. The storage period showed very significantly (P<0.01) increase the specific gravity, pellet durability index, and the insect attacks, and significantly (P<0.01) decreased the water activity, but not effect on water content. Interaction among spraying level and storage period is very significantly (P<0.01) on the values of water content, water activity, specific gravity and pellet durability.

Evaluasi Penggunaan Tepung Keladi terhadap Kualitas Fisik dan Kandungan Nutrien Pelet Pakan Ayam

“…Parameter yang diukur adalah sifat fisik pelet yaitu ketahanan gesekan dan ketahanan benturan. Ketahanan gesekan atau durability pelet diukur dengan metode post tumbling sesuai dengan pendapat Retnani et al (2011). Metode post tumbling dilakukan dengan cara memasukan sampel pelet sebanyak 500 gram ke dalam sebuah drum yang berputar selama 10 menit dengan kecepatan 50 rpm, kemudian disaring dan pelet yang tertinggal pada saringan ditimbang.…”

“…Cutlip et al (2008) menyatakan bahwa proses penguapan dan temperatur mempengaruhi durabilitas pelet. Retnani et al (2011) menyatakan bahwa selain kandungan pati pelet binder yang juga mempengaruhi durability pelet adalah jenis mesin pencetak pelet. Ada dua jenis mesin pelet, yaitu pelet mill dan farm fed peleter.…”

Pengaruh Lama Penyimpanan Terhadap Sifat Fisik Dedak Padi

“…2009). Penyimpanan sangat berperan penting dalam usaha peternakan, karena kegiatan ini dapat menjaga stabilitas penyediaan ransum yang cukup dan aman untuk dikonsumsi ternak (Retnani et al, 2011). Saat masa penyimpanan, bahan pakan sangat dipengaruhi oleh suhu dan kelembapan gudang pakan.…”

The Physical of Biscuit Complete Ration Based on Hymenacne Acutigluma Supplemented with Different Legumes

“…The increase in density due to the supplementation of a legume that is rich in mineral (inorganic). Retnani et al [16] suggest that the density has an important role in the processing, handling, and storage. In addition, specific gravity also has an important role in , 0 (2018) E3S Web of Conferences https://doi.org/10.1051/e3sconf /201868010 68 10 1 st SRICOENV 2018 21 21 the density.…”
