“…The addition of suitable amounts of ingredients with smallsized peptides in feed increased digestive enzyme activity in the intestine of hybrid grouper (Yang et al, 2021), turbot (Jia et al, 2019), and sea bass (Zambonino Infante et al, 1997). Small-size peptide in HFP may play essential roles in regulating enzyme activity by promoting the secretion of digestive enzymes in aquatic animals (Madeira and Paula-Barbosa, 1999).…”

“…Due to its rapid growth rate, hardiness to environmental conditions, high disease resistance, and high nutritional value, it is an ideal species for intensive aquaculture (Ch'ng and Senoo, 2008;Jiang et al, 2015;Arrokhman et al, 2017;Bunlipatanon and U-taynapun, 2017). With regard to marine fish culture output in China, groupers are ranked third (Yang et al, 2021). Hybrid grouper with a higher disease resistance, faster growth rate, and better feed conversion ratio (FCR) was produced at the University of Malaysia Sabah from brown-marbled grouper (Epinephelus fuscoguttatus ♀) and giant grouper (Epinephelus lanceolatus ♂) (Rahimnejad et al, 2015;Firdaus et al, 2016).…”

The effect of hydrolyzed fish protein powder (HFP) on the growth, intestinal development, gene mRNA expression, and enzyme activity in the intestine and liver of juvenile hybrid grouper (Epinephelus fuscoguttatus ♀ and Epinephelus lanceolatus ♂) was assessed after an 8-week feeding trial. Seven isonitrogenous (50%) and isolipidic (9%) diets were fed to hybrid grouper with 0% (CT), 1% (H1), 1.5% (H2), 2% (H3), 2.5% (H4), 3% (H5), and 4% (H6) HFP. No significant difference (p > 0.05) in weight gain rate (WGR), specific growth rate (SGR), feed conversion ratio (FCR), and survival rate (SR) was observed in all the groups. The crude protein content in the H6 group was significantly higher than in the other groups (p < 0.05). Intestinal lipase and trypsin activity were significantly higher in H3 and H5 groups (p < 0.05). In the serum, superoxide dismutase (SOD) activity was significantly higher in H5 and H6 groups, while malondialdehyde (MDA) activity was lower (p < 0.05) compared to other treatments. Insulin-like growth factor (IGF-I) and target of rapamycin (TOR) mRNA expression levels in the intestine and muscle were significantly higher in the H2 group and H1 group (p < 0.05), respectively. The most abundant intestinal bacteria found at the genus level are Acinetobacter, Vibrio, and Flavobacteriaceae. The villus was significantly longer in hybrid grouper fed with different levels of HFP compared to the control, and fish in the H2 group had thicker intestinal muscle compared to the other groups (p < 0.05). In conclusion, the addition of HFP to the low fishmeal (FM) diets of juvenile grouper improved the intestinal development and increased the levels of intestinal digestive enzymes.

“…Similarly, in blunt snout bream [ 67 ] and turbot [ 68 ], FM replaced by alternative proteins also decreased the AA transporters’ expression. A lower level of AA transporters reduced the AA transmembrane transport efficiency, resulting in an overall decrease in muscle AA levels [ 69 , 70 ]. A restricted AA level in muscle would directly affect the activity of nutrient sensing signaling pathways, and further changed the body growth and metabolism [ 27 , 71 ].…”

Our previous study demonstrated that based on growth performance and feed utilization, cottonseed meal (CSM) could substitute 20% fishmeal (FM) without adverse effect on golden pompano (Trachinotus ovatus). Muscle deposition was also an important indicator to evaluate the efficiency of alternative protein sources. Therefore, the present study was conducted to explore the changes of physiobiochemical and nutrient metabolism in muscle after FM replaced by CSM. Four isonitrogenous and isolipidic experimental diets (42.5% crude protein, 14.0% crude lipid) were formulated to replace 0% (CSM0 diet), 20% (CSM20 diet), 40% (CSM40 diet), and 60% (CSM60 diet) of FM with CSM. Juvenile fish (24.8 ± 0.02 g) were fed each diet for 6 weeks. The results presented, which, compared with the CSM0 diet, CSM20 and CSM40 diets, had no effect on changing the muscle proximate composition and free essential amino acid (EAA) concentration. For glycolipid metabolism, the CSM20 diet did not change the mRNA expression of hexokinase (hk), glucose transport protein 4 (glut4), glucagon-like peptide 1 receptor (glp-1r), while over 20% replacement impaired glucose metabolism. However, CSM20 and CSM40 diets had no effect on altering lipid metabolism. Mechanistically, compared with the CSM0 diet, the CSM20 diet did not change muscle nutritive metabolism through keeping the activities of the nutrient sensing signaling pathways stable. Higher replacement would break this balance and lead to muscle nutritive metabolism disorders. Based on the results, CSM could substitute 20–40% FM without affecting the muscle nutritive deposition. All data supplemented the powerful support for our previous conclusion that CSM could successfully replace 20% FM based on growth performance.

“…Porcine mucosal protein hydrolysate (PMH) is obtained from the mucosa of the small intestine of pigs for the production of sodium heparin, an anticoagulant drug (Mateos et al, 2014), and is characterized by a high content of free amino acids, generated from enzymatic hydrolysis (Mora et al, 2014) and low molecular weight peptides (Yang et al, 2021), which makes this ingredient more attractive to animals (Soares et al, 2020;Vázquez et al, 2022), increasing its consumption, as observed in this work, where there was a preference for the ration with the addition of 1% of PMH. This fact may reflect on the growth performance of the animal, since ingestion is essential to ensuring the consumption of the required nutrients (Jingting et al, 2020).…”

“…Low molecular weight peptides have bioactivities that improve that can act as palatabilizers and attractants for the ingestion of offered diets (Saadoui et al, 2019;Yang et al, 2021). Porcine mucosa hydrolyzate (PMH) is an enzymatic hydrolyzate, being a by-product generated from the production process of heparin sodium, an anticoagulant drug (Mateos et al, 2014).…”

Este trabalho teve como objetivo avaliar a inclusão do hidrolisado de mucosa suína (HMS) como estimulante de consumo em dietas para juvenis de tilápias. Para isso, foram utilizados 12 juvenis de tilápias, distribuídos em 12 aquários, onde foram realizadas gravações em vídeo para obter dados de atratividade e palatabilidade: (a) tempo de captura do primeiro pélete; (b) rejeição dos péletes pela tilápia; (c) aproximação sem ingestão; (d) percentual de ingestão; (e) tempo que a tilápia levou para consumir todos os péletes. Foram avaliados seis tratamentos em relação ao controle, sendo eles sem inclusão de HMS e de um a cinco por cento de inclusão do HMS. O tratamento com 1% de inclusão apresentou a maior ingestão dos péletes, e as demais variáveis não diferenças entre os tratamentos avaliados, porém em comparação com o controle, houve uma redução maior no consumo do tratamento com 3% de inclusão. Deste modo, sugere-se a inclusão de 1% do HMS para melhorar a palatabilidade da ração ofertada.
