Ảnh hưởng của hàm lượng vitamin C bổ sung vào thức ăn đến thành phần sinh hóa và hình thái xương cá chim vây vàng <i>Trachinotus blochii</i> (Lacepède, 1801) giai đoạn giống

Abstract

ABSTRACT

This study assessed the effects of different dietary levels of vitamin C (150, 300, 600, 1,200, and 2,400 mg/kg feed) on the biochemical composition and skeletal morphology of juvenile snubnose pompano (Trachinotus blochii). After 10 weeks, results showed that vitamin C supplementation did not affect moisture or ash content but significantly influenced protein and lipid levels in the fish. The highest protein and lipid levels were observed at a supplementation level of 300 mg/kg feed. Furthermore, no skeletal deformities were detected, even in the absence of vitamin C supplementation, possibly because the vitamin C content in the basal diet was sufficient to meet the bone development requirements of juvenile snubnose pompano. These findings provide a scientific basis for optimizing the nutrition of snubnose pompano and suggest further research on vitamin C storage in the liver and muscle tissues of fish.
