Abstract: -The objective of this work was to determine the apparent digestibility coefficient (ADC) of crude protein, crude energy, fat, and dry matter of fish protein hydrolysate (FPH), made of by-products of Nile tilapia (Oreochromis niloticus) and whole sardines (Cetengraulis edentulus), and to evaluate the productive performance and muscle fiber growth of Nile tilapia post-larvae. Two trials were conducted, the first one to determine the digestibility in 120 fingerlings (70.0±2.0 g), and the second one to evaluate t… Show more

“…Also, endogenous enzymes (e.g., proteases existing in fish) continue enzymatic hydrolysis of proteins or exogenous enzymes in order to promote the hydrolytic process, so the molecular size and hydrophobicity of the hydrolysate were strongly influenced (Batista, Ramos, Coutinho, Bandarra, & Nunes, ). The protein availability and subsequent digestibility increased because of small polypeptide chains or short chains of amino acids that produced during the hydrolytic process (Silva, Rocha, Moreira, Signor, & Boscolo, ). Siddik, Howieson, Partridge, Fotedar, and Gholipourkanani () observed increased micromorphology of intestinal parameters such as fold height (hF), microvillous height (hMV) and external circumference of serosa (ECS) with the inclusion of PH in diets which could enhance growth performance of fish through increased nutrient uptake in more surface area, but Cahu, ZamboninoInfante, Quazuguel, and Gall () suggested the saturation of intestinal transport mechanisms by high luminal peptides and amino acids as a possible reason for inferior growth in some species.…”

“…Previous studies demonstrated higher intestinal absorption of PH containing dipeptides and tripeptides than only free amino acids. Dipeptides and tripeptides are absorbed in proximal and distal intestine but amino acids are only absorbed in the former (Silva et al, ). Furthermore, stimulating the secretion of digestive enzymes accounts for a positive effect of fish PHs on fish species (Aguila et al, ; Cahu et al, ; Olivia‐Teles et al, ).…”

“…Research shows that diets containing fish-based hydrolysate proteins blended with other animal's processing wastes, even in low levels, have been presenting positive effects on productive performance, immune system activities and digestibility in the first developmental stages of several species (Chotikachinda et al, 2013;Ovissipour et al, 2014;Srichanun et al, 2014;Silva et al, 2017). Therefore, the present study was designed to determine the compelling palatability of poultry hydrolysate protein (PHF), swine liver hydrolysate protein (PHS), and feather hydrolysate protein (PHP) for Nile tilapia.…”

“…A way of reducing costs with commercial feeds would be the use of agro-industrial by-products, seen that these are currently underutilized or discarded by industries, leading to environmental damage (Decarli et al, 2016). In this context, by-products may be potential raw materials for the production of ingredients such as meals, oils and protein hydrolysates at a low cost (Decarli et al, 2016;Ferreira et al, 2017;Mullen et al, 2017;Silva, Rocha, Moreira, Signor, & Boscolo, 2017).…”

“…Several investigations have been carried out with fish protein hydrolysates and mixtures of other slaughtered animals as a nutritional component of diets, in the initial developmental stages of several fish species, and demonstrated positive effects in productive performance, immunological activities and digestibility (Bernardi et al, 2016;Broggi et al, 2017;Bui, Khosravi, Fourmier, Herault, & Lee, 2014;Chotikachinda, Tantikitti, Benjakul, Rustad, & Kumarnsit, 2013;Decarli et al, 2016;Silva et al, 2017). The inclusion of sardine protein hydrolysate with high hydrolysis degree stimulated the search for food in Rhamdia quelen juveniles (Broggi et al, 2017).…”
