This study assessed the responses of vitamin-D3 intraperitoneally injected to Rohu, Labeo rohita @ of 0 IU/kg bw (only solvent), 100 IU/kg bw and 500 IU/kg bw reared in 20 and 40 ppm of calcium (Ca) enriched water. The cellular changes in Corpuscles of Stannius (CS) gland, serum Ca, and inorganic phosphate (Pi) level were analysed up to the 60th day. Rohu administered with 100 IU/kg bw D3 and exposed to 40 ppm Ca-rich water exhibited notable hyperplasia of CS compared with their control groups. Notable changes with high serum Ca level (13.87 ± 0.3 mg/dl) was detected on the 5th day in fish exposed to 40 ppm Ca-rich water, while related values attained (13.74 ± 0.1 mg/dl) only after 7 days in 20 ppm Ca-rich water of 500 IU/kg bw vitamin D3 injection. Similarly, high serum Pi level (7.66 ± 0.2 mg/dl) in 40 ppm Ca injected with D3 at 500 IU/kg bw. The results demonstrated that the Ca homeostasis of Labeo rohita is influenced by intra-peritoneal vitamin D3. Progressive studies should be conducted by increasing the dose of vitamin D3 to investigate optimum dose/supplement in feed for commercially important aquaculture teleost Labeo rohita for maximum and sustainable absorption of Ca from the variable water Calcium levels to maintain Ca2+ homeostasis.

硬骨Labeo rohita(Hamilton,1822)在水中饲养的钙含量不同的两种浓度下,斯坦尼乌斯小球对腹膜内给予维生素D 3的反应

这项研究评估了腹腔注射Rohu,Labeo rohita @的维生素D 3对0 IU / kg bw(仅溶剂),100 IU / kg bw和500 IU / kg bw在20和40 ppm的钙(Ca )浓缩水。直至第60天,分析了Stannius(CS)腺小体,血清Ca和无机磷酸盐(P i)水平的细胞变化。给予Rohu 100 IU / kg体重的D 3与对照组相比,暴露在40 ppm的富含Ca的水中表现出CS明显增生。暴露于40 ppm高钙水中的鱼在第5天发现高血清钙水平(13.87±0.3 mg / dl)的显着变化,而20的第7天才达到相关值(13.74±0.1 mg / dl)每分钟注射500 IU / kg维生素D 3的ppm高钙水。类似地,在以500 IU / kg bw注射D 3的40 ppm Ca中,高血清P i水平(7.66±0.2 mg / dl)。结果表明,腹腔内维生素D 3影响Labeo rohita的Ca稳态。应通过增加维生素D 3的剂量进行逐步研究研究商业上重要的水产硬骨鱼类Labeo rohita饲料的最佳剂量/补充量,以从可变的水钙水平中最大且可持续地吸收钙,以维持Ca 2+稳态。
