Distillers dried grain can be used as a feed ingredient for the growth of freshwater snail (Semisulcospira coreana) and abalone (Haliotis discus hannai)

Abstract

Two feeding experiments were conducted to evaluate dietary distillers dried grain (DDG) as a feed ingredient that partially replaces soybean meal and wheat flour for the growth of juvenile freshwater snail (Semisulcospira coreana) and abalone (Haliotis discus hannai). Three experimental diets were formulated to contain 0 g kg−1 DDG (DDG0), 200 g kg−1 DDG from rice (diet DDG‐R) and 200 g kg−1 DDG from rice and wheat flour (diet DDG‐RW). In the first experiment, three replicate groups of the freshwater snails averaging 133.0 ± 2.48 mg were fed one of the experimental diets for 12 weeks. Weight gain of the juvenile freshwater snails was not affected by dietary DDG (P > 0.05). In the second experiment, three replicate groups of the juvenile abalones averaging 296.3 ± 1.73 mg were fed one of the three experimental diets for 22 weeks. Weight gain of the abalones was not affected by dietary DDG (P > 0.05). Proximate and amino acid compositions of the whole body in the freshwater snails and soft body in the abalones were not affected by dietary DDG (P > 0.05). The results of the two experiments indicated that DDG can be used as a suitable feed ingredient for partial replacement of soybean meal and wheat flour at a level of 200 g kg−1 in diets without any adverse effects on the growth performance of freshwater snail and juvenile abalone.

“…alam dan budidaya juga 22,3 dan 26,6% lebih berat jika dibandingkan dengan berat cangkang abalon kontrol, dengan ratio berat daging terhadap berat utuh abalon pada penelitian ini berkisar antara 0,68-0,70 (Tabel 5). Nilai rasio pada penelitian ini lebih tinggi jika dibandingkan dengan penelitian Rahman et al (2016) yang melaporkan rasio daging terhadap berat tubuh abalon dengan kisaran 0,62-0,64. Jung et al (2016) melaporkan rasio daging terhadap berat tubuh abalon dengan pakan berbeda mencapai 0,56-0,62.…”
