Effects of Soybean Oil Replacement by Palm Oil on Growth Performance, Muscle Nutritional Composition and Serum Biochemical Indexes of Juvenile Genetically Improved Farmed Tilapia (Oreochromis niloticus)
摘要
Abstract
This experiment was conducted to investigate the effects of soybean oil replacement by palm oil on growth performance, muscle nutritional composition and serum biochemical indexes of juvenile genetically im-proved farmed tilapia (GIFT) (Oreochromis nilotics).A total of 600 juvenile GIFT with an average body weight of 8.80 g were randomly divided into 5 groups with 3 replicates per group and 40 fish per replicate, and fed with their respective diet from the five isonitrogenous (31.60%) and isolipids (9.30%) diets, in which 0 (G0, as control), 25%(G25), 50%(G50), 75%(G75) and 100%(G100) soybean oil were replaced with palm oil in a basal diet.The experiment lasted for 56 days.The results showed as follows:1 ) there was no significant difference in final body weight, weight gain rate, specific growth rate, feed conversion rate and survival rate among all groups (P>0.05).2) Compared with the group G0, there were no significant differ-ences in condition factor, viscerosomtic index, hepatosmatic index and the contents of moisture, crude protein, ether extract and ash in muscle among the palm oil groups ( groups G25, G50, G75 and G100) ( P>0.05) , but the muscle ether extract content in group G50 was significantly higher than that in group G100 ( P<0.05) . 3) No significant differences were found among all groups in serum cholesterol, triglyceride, low density lipo-protein cholesterol and total protein contents with increasing palm oil replacement proportion in diets ( P>0.05) .Serum high density lipoprotein cholesterol content in groups G50 and G100, glutamic-pyruvic transami-nase activity in groups G25 to G50 and glutamic-oxalacetic transaminase activity in groups G50 to G75 were significantly decreased compared with the group G0 ( P<0.05) .The results indicate that soybean oil can be re-placed by palm oil completely in juvenile GIFT diets with the growth performance as the evaluation index. However, significantly differences are observed in muscle ether extract content and some serum biochemical in-dexes when replacement proportion is above 50%.关键词
