Effects of dietaryNutrafito Pluson growth, haemotological parameters and total ammonia-nitrogen excretion of juvenile striped catfishPangasianodon hypophthalmus

Abstract

A feeding trial was performed to determine the effect of a commercial source of Yucca schidigera and Quillaja saponaria extracts (Nutrafito Plus®), in practical diets, on striped catfish Pangasianodon hypophthalmus growth, feed utilization, body composition, total ammonia‐nitrogen (TAN) excretion and haematological parameters. Four experimental diets were supplemented with Nutrafito Plus® at 0%, 0.01%, 0.02% and 0.03% (diets: control, N01, N02 and N03 respectively). Three replicate groups of striped catfish, with initial mean weight of 1.78 ± 0.05 g, were fed one of the four diets for 12 weeks. The specific growth rate (SGR) and final weight of fish fed diet N03 was significantly higher (P < 0.05) than fish fed the other dietary treatments. The growth performance of fish fed diets N01 and N02 were not significantly different compared to fish fed the control diet. Striped catfish fed diet N03 had improved feed conversion ratio (FCR), net protein utilization (NPU) and protein efficiency ratio (PER) than the control (P < 0.05). The inclusion of the high dietary level of Yucca schidigera and Quillaja saponaria, diet N03, reduced TAN compared to all groups. Dietary inclusion of Yucca schidigera and Quillaja saponaria at all levels investigated did not affect the whole body proximate composition of the striped catfish (P > 0.05). The packed cell volume (PCV) and haemoglobin level in fish fed diet N03 was significantly higher than in the fish fed the control diet. The present study demonstrates that dietary inclusion of Yucca schidigera and Quillaja saponaria induced positive effects on growth performance and haematological parameters and decreased TAN excretion in striped catfish.

Quillaja saponaria and/or Yucca schidigera ameliorate water quality, growth performance, blood health, intestine and gills histomorphology of Nile tilapia, Oreochromis niloticus

“…The present study demonstrated that the lowest significant value of TAN and UIA was reported in QS/YS, YS and QS compared with CG. These results correspond with Güroy et al (2016) who found a significant reduction in TAN excretion with 0.3% dietary inclusion of YS and QS extract to the juvenile striped catfish diet, compared to the control. In this context, many studies have focused on the role of YS in mitigating ammonia in aquaculture water with promising findings (Castillo Vargasmachuca et al, 2015;Hassan et al, 2017;Yang et al, 2015;Yu et al, 2015).…”

The effects of dietary Eleutherine bulbosa on the growth, leukocyte profile, and digestive enzyme activity of the striped catfish Pangasianodon hypophthalmus

“…Dorojan et al (2015) also reported that fish fed diets containing at least 200 mg kg -1 of ginseng herb (Ginsana® G115) for 17 weeks, had enhanced growth performance, feed efficiency, and hematological indices. Similar results concerning the effect of a commercial source of Yucca schidigera and Quillaja saponaria extracts (Nutrafito Plus®), in practical diets, on striped catfish P. hypophthalmus growth, feed utilization, and hematological parameters have also been reported by Guroy et al (2016). .…”

Dietary Supplementation of a Mixture of Saponin-Rich Plants to Reduce Ammonia-Nitrogen Excretion in Juvenile Nile Tilapia (<i>Oreochromis</i> <i>niloticus</i>)

“…Güroy et al [20] showed a beneficial impact of a supplementation of juvenile striped catfish (Pangasianodon hypophthalmus) with a mixture of Y. schidigera and Q. saponaria, on the fish growth. Overall, in results obtained in the litterature on the use of saponin-rich plants in aquaculture, an improvement seems to be observed for supplementation doses lower than 1000ppm.…”

“…Finally, Güroy et al, reported a beneficial impact of a supplementation of juvenile striped catfish (P. hypophthalmus) with a mixture of Y. schidigera and Q. saponaria, on the fish TAN reduction, associated with an improvement in fish growth [20].…”
