“…In recent years, functional diet supplementation has become a topic of interest for improving not only growth rate and feed utilization but also health status of farmed fish (Tiengtam, Khempaka, Paengkoum, & Boonanuntanasarn, 2015). Proteases were added to feed with the purpose of increasing dietary protein hydrolysis, thus enabling improved nitrogen utilization (Oxenboll et al, 2011), which has been shown to have beneficial effects on growth and physiological state of fish and poultry (Li et al, 2015;Peek et al, 2009). In our study, the protein content in the PC diet has been shown to be suitable for Gibel carp (Qian, 2001 fish fed the NC diet without protease supplement, and with increasing values with incremental increases in dietary protease up to 300 mg/ kg, and the FCR and PER were also improved in fish fed the diets with supplemented with protease.…”

“…() reported that adding protease in low fishmeal pelleted diet, but not to the extruded diet, improved the growth and nutrient utilization of large Carassius auratus gibelio (35.0 ± 0.2 g), but the dietary protease on physiology and biochemistry of Carassius auratus gibelio was not involved. Nevertheless, Peek, Van der Klis, Vermeulenc, and Landmana () reported that the adherent mucus layer of the duodenum, jejunum and caeca was significantly thicker in broiler chickens fed the protease‐supplemented diet.

This study was conducted to investigate the effects of dietary protease on growth performance, feed utilization, whole-body proximate composition, nutrient digestibility, intestinal and hepatopancreas structure of juvenile Gibel carp, Carassius auratus gibelio (mean weight 8.08 ± 0.18 g). Six diets were prepared, including a positive control diet (dietary protein 350 g/kg, PC), one negative control diet (dietary protein 33 g/ kg, NC) and four protease supplementations diets, which were 75, 150, 300 and 600 mg/kg protease NC diet. After 12 weeks of diet feeding in indoor recycle aquarium tanks, no significant difference (p > .05) was found on growth performance between fish fed diet with 75-600 mg/kg protease and the PC group. Compared with the fish fed the NC diet, the specific growth rate of fish fed 300 mg/kg protease increased significantly (p < .05), as well as protein efficiency ratios (p < .05), while feed conversion was the opposite (p < .05). The nutrient digestibility of crude protein and lipid was higher (p < .05) in fish fed 150 mg/kg protease diet than the PC diet. Wholebody proximate composition of fish was not affected (p > .05) by the dietary treatment. Serum alkaline phosphatase and albumin were significantly affected by dietary protease (p < .05), while the content of total protein, glucose, triglyceride, total cholesterol, aspartate aminotransferase and alanine aminotransferase activities in serum was not affected (p > .05). Foregut muscular thickness was thinner (p < .05), when the fish fed diets supplementation of protease in 150 or 600 mg/kg diet than the NC diet.Protease activities in hepatopancreas and foregut were higher (p < .05), in the fish fed 150 or 300 mg/kg protease diet than the fish fed the PC diet, but those in the mid-and hindgut were not significantly affected (p > .05) by the dietary treatments. Based on the regression analysis of weight gain rate, the optimal dietary inclusion level of protease was 400 mg/kg in the diet for juvenile Carassius auratus gibelio.

“…Peek et al (2009) suggest that higher mucosal turnover in the jejunum might represent a lower mucosal protection against an Eimeria infection. The phenomenon of changes of mucin quantity in the jejunum compared to the mucin layer in the duodenum was documented in our experiment.…”

We studied the effect of oregano supplemented diet on mucin dynamics in small intestine, peripheral blood leukocytes, and jejunal immunocompetent cells in ROSS 308 hybrid broilers infected with Eimeria acervulina chickens' oocyst. From the day of hatching chicks of groups 1 and 2 were fed a commercial diet without anticoccidial drug, the diet of group 3 was supplemented with oregano (0.707g·kg -1 ), and that of group 4 with anticoccidial drug (Robenidin hydrochloride -33 mg·kg -1 ). Chickens of groups 2, 3, and 4 were inoculated with E. acervulina oocysts (25.10 3 ) on day 12. The samples were collected on 3, 10, 17 days post infection (dpi). In blood on 3 dpi significant increase of leukocytes was found in group 3 compared to groups 1, 2, and 4, higher density of IgM+ cells in group 3 than group 2, and on 10 dpi phagocytic activity of group 3 was higher than group 1. Number of jejunal CD4+ and CD8+ cells in group 3 was consistent with values in group 4, despite higher density of E. acervulina meronts on 10 dpi. The quantity of jejunal mucin adherent layer of group 3 was similar to that in group 4. Counts of oocysts in faeces were lower in group 3 than group 2. Results suggest that dietary supplementation of oregano to chickens infected with E. acervulina has a modulating effect on some blood indicators and functions of phagocytes. The beneficial effect of oregano components on jejunal mucin quantity and its turnover is the first finding published in relation to oregano and coccidia.

“…Since enzyme supplementation promotes a better distribution of the nutrients in the organism of the layer (Selle & Ravidran, 2007), it enables a better structure for intestinal protection of the layers and a greater efficiency in this defense. To evaluate such effects, Peek (2009), working with protease supplementation in the diet of broilers, observed that supplementation improved the health of the animals, for the incidence of eimeriosis was reduced. This fact was corroborated by this study, because with supplementation of enzyme complex, the bacterial count was reduced (Table 8).…”

“…Enzymes are added to animal feed in order to increase digestibility (Li et al, 2010), to remove antinutritional factors, and to improve nutrient availability, as well as for environmental reasons, and can be an improvement to intestinal health in relation to bacterial contamination (Peek, 2009). A large variety of carbohydrases, proteases, phytases and lipases are used for these purposes.…”

-The objective of this study was to evaluate the reduction of protein, the formulation of diets and supplementation of an enzyme complex for laying hens. The layers were distributed in a completely randomized 2 × 2 × 2 factorial arrangement, with two levels of crude protein reduction (0.0 and 4.0 g/kg), two kinds of diet formulation (without and with reformulation, considering 75 kcal of metabolizable energy) and two enzyme supplementations (without and with enzyme complex supplementation), totalizing 8 treatments of 8 layers each, with 7 replications, in a total of 448 laying hens at 30 weeks of age. After data analysis, it was found that the enzyme complex supplementation in the diet of layers improves performance, promotes a similar egg quality and improves the bone and intestinal health of the layers.
