dietary arginine surplus does not improve intestinal Nutrient Absorption capacity amino acid metabolism and oxidative status of gilthead sea bream sparus aurata juveniles
Aquaculture, 2016Co-Authors: Filipe Coutinho, C. Castro, M.a. Gallardo, Sadasivam Kaushik, Eva E Rufinopalomares, Borja Ordonezgrande, Aires Olivateles, H. PeresAbstract:Abstract This study aims to evaluate the effects of dietary arginine (Arg) surplus on gilthead sea bream growth, intestinal Nutrient Absorption capacity, hepatic and intestinal amino acid (AA) metabolism, and oxidative status. For that purpose a 6 weeks growth trial was performed with gilthead sea bream juveniles fed four isolipidic (18%) and isoproteic (44%) diets supplemented with 0, 0.5, 1 and 2% Arg. Dietary Arg did not affect fish growth performance, feed and nitrogen utilization, body composition, and activity of the main AA catabolic enzymes in liver and intestine. Similarly, intestinal Nutrient Absorption capacity, evaluated by intestinal brush border membrane vesicles technique, was also unaffected by the dietary Arg surplus. On the other hand, enzymatic antioxidant response was modulated by dietary Arg increment, which led to a reduced glutathione peroxidase activity in the liver and the intestine and increased superoxide dismutase activity in the intestine, but did not affect the overall lipid peroxidation values. Some differences in liver and intestine antioxidant enzymatic responses were identified, with the liver showing higher catalase and glucose-6-phosphate dehydrogenase activities, while the intestine presented higher glutathione peroxidase and glutathione reductase activities. Overall, dietary Arg excess showed limited potential to enhance gilthead sea bream performance and intestinal Nutrient Absorption capacity, but it was shown to modulate hepatic and intestinal antioxidant defences, without affecting overall lipid peroxidation. Statement of relevance Recently some fish species have been shown to benefit from dietary arginine surplus, while evidences also exist of an Arg-Lys antagonism in other fish species. This manuscript gives further insight on the potential of dietary arginine supplementation in gilthead sea bream, a major aquaculture species in the Mediterranean.

different characteristics of Nutrient Absorption and utilization between inbred japonica super rice and inter sub specific hybrid super rice
Field Crops Research, 2018Co-Authors: Haiyan Wei, Ying Zhu, Leiming Zheng, Zhifeng Chen, Peiyuan Cui, Baowei Guo, Qigen Dai, Hongcheng ZhangAbstract:Abstract Although previous researchers have revealed that inter-sub-specific hybrid rice between indica and japonica has super-high yield potential, the mechanisms underlying Nutrient Absorption and utilization remain limited. The present study assessed Nutrient accumulation and utilization, root morphology, and physiology of inter-sub-specific hybrid super rice cultivars (IHSRC) Yongyou 12 and Yongyou 15, using inbred japonica super rice cultivars (IJSRC) Nanjing 44 and Ningjing 3 as control. Total nitrogen (N), phosphorus (P), and potassium (K) accumulations in IHSRC were 12.53%, 20.81%, and 17.30% higher than those in IJSRC respectively. The larger amounts of accumulated Nutrients in IHSRC were mainly attributable to the high rates of Nutrients accumulation before elongating and the long growth duration without premature senescence after elongating. The apparent recovery efficiency of N fertilizers, agronomic N use efficiency, and the partial factor productivity of applied N in IHSRC were all higher than those in IJSRC, whereas the physiological N use efficiency and internal N, P, and K use efficiencies of IHSRC were similar to or lower than those of IJSRC. Compared with IJSRC, the root weights of IHSRC were heavier with greater length and bigger volume, the total and active Absorption areas were also larger. In conclusion, with strong and active root systems, IHSRC are more efficient in Nutrient Absorption than utilization.
