dc.description.abstractA 60-day feedingtrial was conducted to asses the potential nutritive value of sesame seed mealas a dietary replacement for soybean meal in the diets of rainbow trout (Oncorhynchus mykiss Walbaum, 1792). Alldiets were prepared to be isonitrogenous (49% protein), isolipidic (19% lipid)and isoenergetic (22 kJ g-1). Four different diets containing 0% (C), 10%(10SSM), 15% (15SSM) and 20% (20SSM) sesame seed meal were formulated forrainbow trout with a mean weight of 81.02±0.02 g and fish were hand fed feedtwice a day to apparent satiety under a natural light regime. At the end ofstudy, significant differences were found in final body weight, weight gain andspecific growth rate (SGR, %) between control group (C) and the experimentalgroups (p<0.05). While there were no significant differences between theexperimental groups in terms of feed conversion ratio (FCR) and proteinefficiency rate (PER) (p>0.05), Apparent Net Protein Retention (ANPR)differed significant between C and 10SSM and 15SSM and 20SSM groups(p<0.05). The moisture, protein, lipid and ash contents in the bodycomposition of the fish increased in all experimental groups. The moisture, lipidand ash content were not significantly differed among the groups (p>0.05)but protein contents of fish in 15SSM and 20SSM groups was significantly higherthan fish in control and 10SSM groups (p<0.05). There were also nodifferences in the digestibility of crude protein among groups (p>0.05).Comparable performance in growth, nutrient utilization and crude proteindeposition of rainbow trout fed by diet containing 15% sesame seed meal showedthat these meals could be used as this rate.
dc.description.abstract60 günlük beslemedenemesi, gökkusagi alabaligi (Oncorhynchusmykiss Walbaum, 1792) diyetlerinde soya küspesi yerine susam tohumuküspesinin potansiyel besleme degerini degerlendirmek için yapilmistir. Tümdiyetler izonitrojenik (%49 protein), isolipidik (% 19 yag) ve isoenerjik (22kJ g-1) olarak hazirlanmistir. %0 (C), %10 (10SSM), %15 (15SSM) ve %20 (20SSM)susam tohumu küspesi ihtiva eden dört farkli diyet ortalama agirligi 81.02 ±0.02 g olan gökkusagi alabaliklari için formüle edilmistir ve baliklar dogalisik rejimi altinda görülebilir tokluga ulasincaya kadar günde iki kez ellebeslenmistir. Çalismanin sonunda, kontrol (C) ve diyet gruplari arasinda finalvücut agirligi, agirlik kazanci ve spesifik büyüme oraninda (SGR,%) önemlifarkliliklar bulunmustur (p<0.05). Yem dönüsüm orani (FCR) ve protein etkinlik orani (PER) açisindan deneygruplari arasinda anlamli bir fark yokken (p>0.05), Görünen Net ProteinTutumu (ANPR) bakimindan C-10SSM ve 15SSM-20SSM gruplari arasindakifarkliliklarin önemli oldugu belirlenmistir (p <0.05). Baliklarin vücutkompozisyonundaki nem, protein, lipit ve kül içerikleri tüm deneme gruplarindaartmistir. Nem, yag ve kül miktari bakumindan farkliliklar gruplar arasindaönemli bulunmamistir (p> 0.05),  fakat15SSM ve 20SSM diyetleriyle beslenen baliklarin protein içerikleri C ve 10SSMdiyetleriyle beslenen baliklardan daha yüksek oldugu belirlenmistir. Bu gruplararasindaki farkliliklar önemli bulunmustur (p<0.05). Gruplar arasinda hamprotein sindirilebilirlik oraninda önemli farklilik tespit edilmemistir(p>0.05). %15 susam tohumu küspesi içeren diyetle beslenen gökkusagialabaliklarinin büyüme, besin kullanimi ve ham protein birikimindeki performanskarsilastirildiginda, susam tohumu küspesinin bu oranda kullanilabileceginigöstermistir.
