Effects of dietary vitamin B₁on growth performance, blood metabolites, body composition, intestinal enzyme activities and morphometric parameters of juvenile yellow catfish (Pelteobagrus fulvidraco)

Abstract

The effects of vitamin B1 on growth, blood metabolites, body composition, intestinal enzyme activities and morphometric parameters were evaluated by a 63‐day feeding trial in Pelteobagrus fulvidraco fed diets containing vitamin B1 with 4.29, 6.02, 7.86, 11.94 and 19.05 mg/kg, respectively. Results showed that 7.86 mg/kg vitamin B1 resulted in significantly higher weight gain (WG), specific growth rate (SGR) and protein efficiency ratio (PER) (p < .05). Serum triglyceride, cholesterol and whole‐body lipid were observed in 11.94 mg/kg vitamin B1 group significantly higher than those in 4.29 mg/kg group, accompanied by the lower serum glucose content in the same group (p < .05). Significantly higher values of whole‐body protein, serum total protein, relative intestinal length, fold height, intestinal trypsin, amylase, alkaline phosphatase, Na+/K+‐ATPase, γ‐glutamyl transpeptidase, creatine kinase, muscular layer thickness and intestosomatic index were observed in 7.86 mg/kg vitamin B1 group compared with those in 4.29 mg/kg group (p < .05). These results suggested that diets supplemented with vitamin B1 improved growth performance, feed utilization, intestinal digestive and absorption capacity of juvenile yellow catfish. The optimal dietary vitamin B1 requirements estimated using a two‐slope broken‐line model based on WG and PER of yellow catfish were 7.42 and 6.01 mg/kg, respectively.

Effects of dietary thiamin (vitamin B1) on the growth performances, serum biochemistry factors, immune response, and antioxidant activity of great sturgeon (Huso huso) juveniles

“…activity of trypsin, chymotrypsin, amylase, and lipase increased signi cantly with the consumption of thiamin-supplemented diets. These results are consistent with ndings reported in Jian carp(Huang et al 2011), golden pompano(Xun et al 2019), and yellow cat sh (Pelteobagrus fulvidraco) juveniles(Zhao et al 2020). In contrast with the present study,Xun et al 2019 reported that dietary thiamin content did not signi cantly affect amylase activity in golden pompano.…”

“…In the present study, TP, TG, and CHO were signi cantly affected by different levels of thiamin. Similar results were reported byZhao et al 2020. The results obtained herein from the evaluation of blood metabolites show that the concentration of thiamin in the diet at 15 and 25 mg/kg feed increases serum TP contents with no signi cant difference between them.…”

“…In contrast with the present study,Xun et al 2019 reported that dietary thiamin content did not signi cantly affect amylase activity in golden pompano. The elevated activity of intestinal enzymes with thiamin may be related to the integrity, growth, and development of digestive organs in sh(Zhao et al 2020). Creatine kinase (CK) is involved in the energy metabolism of cells and catalyzes the transfer of phosphate to creatine in an ATP-dependent manner(Zhao et al 2020).…”

Creatine kinase (CK) is involved in the energy metabolism of cells and catalyzes the transfer of phosphate to creatine in an ATP-dependent manner(Zhao et al 2020). ALP is an important enzyme in the absorption of nutrients such as lipids, glucose, calcium, and inorganic phosphate(Tengjaroenkul et al 2000).…”

Effects of dietary sodium butyrate on growth, digestive enzymes, body composition and nutrient retention-related gene expression of juvenile yellow catfish (Pelteobagrus fulvidraco)

“…Wheat flour, fish oil and soybean oil were used as carbohydrate and lipid sources. The levels of nutrients met the requirements of yellow catfish according to previous studies conducted in our laboratory ( Cao et al, 2012 ; Chen et al, 2016 ; Zhao et al, 2020 ). Five isonitrogenous and isolipidic diets were formulated to contain SB at 0 (control), 250, 500, 1,000 or 2,000 mg/kg, by supplementing SB (purity ≥ 98%).…”
