The effects of dietary supplementation with butyrate and polyhydroxybutyrate on the digestive capacity and intestinal morphology of Pacific White Shrimp (Litopenaeus vannamei)

Effect of Halomonas storage poly‐β‐hydroxybutyrates on survival, growth and vibriosis resistance of half‐smooth tongue sole Cynoglossus semilaevis juveniles

“…We observed increased intestine fold, epithelium height and surface of the fish fed 3% HM.PHB. This accords with the observation that L. vannamei fed with PHB‐supplemented diet presented increase in the length and width of intestinal villi (Silva et al., 2018). The improved intestinal condition should benefit the nutrient absorption and contribute to the better growth and survival of the fish.…”

Supplementation of tributyrin, alone and in combination with fructooligosaccharide in high soybean meal diets for shrimp ( Litopenaeus vannamei ): Effects on growth, innate immunity and intestinal morphology

“…Digestive enzyme activities are strongly related to growth and feed utilization, especially trypsin, amylase and lipase. In the present study, shrimp fed high SBM‐based diet showed remarkably lower trypsin and lipase activities in the hepatopancreas, the principal digestive organ in shrimp (Silva et al., 2016), whereas adding TB in the diet could significantly increase the trypsin activity. These results are in line with the findings of the earlier works in juvenile black sea bream ( A. schlegelii ) (Volatiana, Sagada, et al, 2019; Volatiana, Wang, et al, 2019) and juvenile yellow drum ( Nibea albiflora ) (Tan et al., 2020).…”

“…Silva et al. (2016) found that butyrate supplementation in shrimps ( L.vannamei ) diet increased intestinal lipase and hepatopancreatic trypsin activities. Several reports have shown that oligosaccharide‐supplemented diets result in increased digestive enzyme activity in aquatic animals such as freshwater crayfish ( Cherax destructor ) (Sang et al., 2011), Caspian roach ( Rutilus rutilus ) (Soleimani et al., 2012), blunt snout bream ( Megalobrama amblycephala ) (Zhang et al., 2014), triangular bream ( Megalobrama terminalis ) (Zhang et al., 2015) and regal peacock ( Aulonocara stuartgranti ) (Mirzapour‐Rezaee et al., 2017).…”

“…Butyrate, the principal energy source for intestinal epithelial cells, has been confirmed to show positive effects, especially in improving intestinal morphological structure and modulating intestinal microbiota by reduced pH level and inhibited pathogens (Aalamifar et al., 2020; Abdel‐Latif et al., 2020; Robles et al., 2013; Silva et al., 2016). However, butyrate usage in feed is greatly limited owing to its tasteful odour, volatility, corrosivity and rapid absorption before arriving in the small intestine (Mallo et al., 2012).…”

Effects of dietary supplementation of monobutyrin and tributyrin on growth, feed efficiency, innate immunity, digestibility and disease resistance of Pacific white shrimp ( Litopenaeus vannamei ) against Vibrio harveyi

“…Also, they easily chelate cations to increase the absorption of P, Ca and other minerals (Boling‐Frankenbach et al, 2001; Øverland et al, 2000). Organic acids increase the nutrient digestion and absorption ability, thereby improving the growth of shrimps (Duan et al, 2017; Romano et al, 2016; Silva, Jesus, et al, 2016). In a search to improve efficiency and ability of the organic acids along the gastrointestinal tract, an encapsulated organic acids and salts, and non‐smelling and non‐corrosive (poly) esters of organic acids have been investigated.…”
