Abstract

This study was carried out to determine the effects of the inclusion of high level of potato starch (27%) on growth performance, blood parameters and intestinal bacteria of rainbow trout, Oncorhynchus mykiss. A 60-day feeding trial was carried out on triplicate groups of 180 fish (mean ± standart devision =17.03 ± 2.68) in 140-L fiberglass tanks. There were no significant differences in haematological variables such as red blood cell count, hematocrit ratio, hemoglobin concentration; in immunological variable such as respiratory burst activity, and in serum biochemical variables such as total protein, albumin, globulin, triglyceride, cholesterol, and glutamic-pyruvic transaminase of fish fed experimental diets. However, 27% potato starch supplementation negatively affected growth performance (FCR, SGR and weight gain), some immunological parameters (lysozyme and myeloperoxidase activities), and some serum biochemical variables (glucose, lactate dehydrogenase, glutamic oxaloacetic transaminase, alkaline phosphatase). In addition, the total counts of bacteria and lactic acid bacteria in the 27% potato starch supplementation group was found to be significantly higher than the control group (p<0,05). The results of the study revealed that the supplementation of high level of potato starch (27%) in aquafeed has been found to cause undesirable effects on rainbow trout

Özet

Bu çalışma gökkuşağı alabalığı, Oncorhynchus mykiss yemlerine yüksek oranda patates nişastası (% 27) ilavesinin balıkların büyüme performansı, kan parametreleri ve bağırsak bakterileri üzerine etkisini belirlemek için yapılmıştır. 140 L tanklarda üç tekrarlı yürütülen besleme denemesinde 180 adet balık (ortalama ± standart sapma= 17,03 ± 2,68) kullanılmıştır. Hematolojik değişkenlerden kırmızı kan hücresi sayısı, hematokrit oranı, hemoglobin konsantrasyonu; immünolojik değişkenlerden respiratori bürst aktivitesi; biyokimyasal değişkenlerden toplam protein, albümin, globülin, trigliserit, kolesterol ve glutamik-piruvik transaminaz deneme grupları arasında önemli bir değişim göstermemiştir. Ancak, % 27'lik patates nişastası ilavesi, büyüme performansını (SBO, YDO ve ağırlık artışı), bazı immünolojik parametreleri (lizozim ve miyeloperoksidaz aktiviteleri) ve bazı serum biyokimyasal değişkenleri (glukoz, laktat dehidrojenaz, glutamik oksaloasetik transaminaz, alkalin fosfataz) olumsuz yönde etkilemiştir. Ek olarak, toplam bakteri ve laktik asit bakterilerinin sayısı % 27'lik patates nişastası ilaveli grupta kontrol grubuna göre önemli derecede fazla bulunmuştur(p<0,05). Genel olarak, bu çalışmadan elde edilen sonuçlara dayanarak, yeme yüksek miktarda patates nişastası (% 27) ilavesinin gökkuşağı alabalığı üzerinde istenmeyen etkilere neden olduğu bulunmuştur.
