Abstract

Highlight ResearchEffects of carboxymethyl cellulose (CMC) binder on pellet water stability in shrimp diet.Evaluation of squid oil attractant on feed palatability.The quality of water after inclusion of CMC binder and squid oil in pellet.CMC and squid oil improved dry matter retention and feeding responses in shrimp. AbstractPellet water stability and feeding attractant are the crucial factors to be considered in the formulation of shrimp feed to minimize nutrient leaching and improve food palatability, respectively. The aim of this study was to determine the binding effect of supplementation of carboxymethyl cellulose (CMC) during pellet manufacturing, and feeding responses with the inclusion of squid oil in pellet. Both experiments were conducted separately in five feed formulations ranged from 0.00% to 3.00% of CMC and squid oil. All T0 was referred as control with no CMC or squid oil. Experiment was conducted using 30 shrimps/treatment with triplicates. The dry matter retention up to 120 min of immersion and the feeding response test were evaluated in pellet supplemented with CMC and squid oil, respectively. Results showed the percentage of dry matter retentions increased with the increase of CMC, over time. The CMC containing pellets at 2.00% and 3.00% had minimal disintegration in water and possessed high water stability after 120 min immersion. The addition of 3.00% squid oil in feed exhibited a significant result (p<0.05) in the time taken for shrimp to access the pellet, also increased the time starts for ingestion. No significant change was observed in water quality indicated no water contamination occurred throughout the study. Results demonstrated that the addition of CMC binder at 2.00% and 3.00% improved pellet water stability, whilst 3.00% squid oil was recommended to enhance feed palatability.

羧甲基纤维素（CMC）粘合剂和鱿鱼油引诱剂在凡纳滨对虾日粮配方中的评价

羧甲基纤维素(CMC)粘结剂对虾饲料中颗粒水稳定性的影响。鱿鱼油引诱剂对饲料适口性的影响。对CMC粘结剂与鱿鱼油包合后的水质进行了研究。CMC和鱿鱼油改善了虾的干物质保留和摄食反应。摘要颗粒水稳定性和饵料引诱剂分别是对虾饲料配方中减少养分淋失和提高食品适口性的关键因素。本研究的目的是确定在颗粒制造过程中添加羧甲基纤维素(CMC)的结合效果，以及在颗粒中加入鱿鱼油的摄食反应。两项试验分别在0.00% ~ 3.00% CMC和鱿鱼油的5种饲料配方中进行。所有T0均为对照组，不加CMC或鱿鱼油。试验选用30只对虾/处理，设3个重复。分别对添加CMC和鱿鱼油的颗粒进行浸泡至120 min时的干物质保留率和摄食反应试验。结果表明，随着时间的推移，干物质保留率随CMC浓度的增加而增加。含2.00%和3.00%球团的CMC在水中崩解最小，浸泡120 min后具有较高的水稳定性。饲料中添加3.00%鱿鱼油显著影响了对虾接近颗粒的时间(p<0.05)，并延长了对虾开始摄食的时间。在整个研究过程中，没有观察到水质的显著变化，表明没有发生水污染。结果表明，添加2.00%和3.00% CMC粘结剂可提高颗粒的水稳定性，添加3.00%鱿鱼油可提高饲料的适口性。然而，对处理后虾体酶活性的进一步研究将是一个优势。
