Ginger oil, Zingiber officinale, improve palatability, growth and nutrient utilisation efficiency in Nile tilapia fed with excess of starch

Dietary Supplementation with Ginger (Zingiber officinale) Residue from Juice Extraction Improves Juvenile Black Rockfish (Sebastes schlegelii) Growth Performance, Antioxidant Enzyme Activity and Resistance to Streptococcus iniae Infection

“…Ahmadifar et al [ 40 ] reported an increase in enzyme activity (amylase) in fish fed 0.1–0.3% dietary ginger powder, but no effect on growth (SGR). In contrast, Cardoso et al [ 20 ] observed improvements in O. niloticus growth with ginger supplementation but no differences in digestive enzyme activity (protease, lipase, and amylase).…”

“…These authors also described that zingiberene is the most concentrated compound in the dehydrated ginger powder, terepene is known for its smell and flavor [ 37 ], and this substance improved the feed intake and feed conversion ratio, resulting in enhanced growth and PER. Ginger oils are known to enhance palatability, which may reflect improved FE and fish growth, as reported for O. niloticus [ 20 ]. Ginger extracts also stimulate digestive enzyme secretion in Oncorhynchus mykiss and Mesopotamichthys sharpeyi , improving growth performance through better feed utilization [ 38 , 39 ].…”

“…Dietary GRJE supplementation significantly improved rockfish growth (final weight, weight gain, and SGR) and feed utilization (FE and PER), even at the lowest dose (0.25% GRJE). Numerous studies have shown that dietary supplementation with various types and concentrations of ginger significantly affects growth and feed utilization in fish [ 1 , 20 , 21 , 34 , 35 , 36 ]. Similar to our study, Naliato et al [ 19 ] showed that growth performance parameters of Oreochromis niloticus including final body weight, WG, SGR, feed intake and feed conversion ratio, and PER were responsive to the increase on dietary ginger powder supplementation, showing a dose-dependent response and a linear correlation.…”

“…Among medicinal plants, ginger ( Zingiber officinale Roscoe) has been widely studied due to its antioxidant [ 9 ], antibacterial [ 10 , 11 , 12 , 13 ], antiparasitic [ 14 ], anti-inflammatory [ 1 ], immunostimulatory [ 15 , 16 , 17 ], and growth-promoting [ 1 , 17 , 18 ] properties. The benefits of ginger powder, ginger essential oil, and ginger extracts as a diet supplement for fish have been reported [ 6 , 19 , 20 , 21 ]. However, the efficacy of using a ginger by-product from juice extraction as a feed supplement for black rockfish ( Sebastes schlegelii ) has not been investigated.…”
