“…Interestingly, the fish with a higher blood profile (PHB 1.0) were found to have higher blood performance than the control, which indicates better fish health. Similar results were reported for combined medicinal herbs [12] and figwort, Scrophularia striata, fed to common carp [40]. Furthermore, the considerable rise in the heterophil counts observed in PHB-0.5 and PHB-1.0 could be indicative of innate immune system stimulation and the PHB's potential to activate heterophils in African catfish.…”

A 56-day feeding trial was conducted to evaluate the dietary effect of Nigeria polyherbal mixture (PHB) on growth, haemato-immune parameters, antioxidant enzyme activities, and intestinal morphometry of African catfish, Clarias gariepinus. Four diets were formulated with PHB powder at inclusion of 0 g/kg (control), 0.5 g/kg (PHB 0.5), 1.0 g/kg (PHB 1.0), and 2.0 g/kg (PHB 2.0) and fed to African catfish ( 6.32 ± 0.02 g /fish, 15 fish/50 L tank) in triplicates. Fish fed PHB 2.0 recorded higher final weight, weight gain, and specific growth rate ( p < 0.05 ) compared to the control. There were no statistical differences ( p > 0.05 ) in feed conversion ratio and protein efficiency ratio among the dietary groups. The haematological profile indicates that the fish fed PHB-1.0 had higher Hb, RBCs count, and Hct, and blood performance ( p < 0.05 ) compared to the control. ALT levels were found higher in the control and the lowest values recorded in PHB groups ( p < 0.05 ); however, AST did not differ significantly among the groups ( p > 0.05 ). The highest heterophil counts and respiratory burst activity were recorded in PHB-1.0 and PHB-0.5 and PHB-2.0, respectively, while a numerically improved total immunoglobulin value was recorded in PHB-0.5 compared to the control ( p > 0.05 ). Antioxidant enzymes such as superoxide dismutase and catalase had a significant improvement in fish fed PHB-based diet compared to the control ( p < 0.05 ), while glutathione peroxidase showed no statistical differences between the groups ( p > 0.05 ). Intestinal morphometric measurements showed that the fish fed PHB-1.0 had the highest villus height, area of absorption, and villus height/cryptal depth ratio compared to the control. Muscle thickness increased ( p < 0.05 ) with increasing PHB level with the highest value recorded PHB-2.0. In conclusion, dietary PHB could improve growth, blood profile, immunity, antioxidant enzyme capacity, and intestinal morphometry of African catfish without any significant alteration in the liver function enzymes.

Early-life exposure to mild stressors can assist animals in coping with more stressful events in later life. This study was aimed at investigating how early stress and dietary lipid contents affect growth, hematology, blood biochemistry, immunological responses, antioxidant system, liver enzymes, and stress responses of oscar (Astronotus ocellatus) ( 6.8 ± 0.7 g). Six experimental treatments were HL0Stress (high-lipid diet and without stress), HL2Stresses (high-lipid diet and two-week stress), HL4Stresses (high-lipid diet and four-week stress), LL0Stress (low-lipid diet and without stress), LL2Stresses (low-lipid diet and two-week stress), and LL4Stresses (low-lipid diet and four-week stress). During the ten-week trial, fish fed high-lipid diets grew faster ( 46.41 ± 4.67 vs. 38.81 ± 2.81 ) and had a lower feed conversion ratio (2.21 vs. 2.60) than those fed low-lipid diets ( P < 0.05 ). After acute confinement stress (AC stress), high-lipid groups had higher survival than low-lipid treatments (81.25% vs 72.92%) ( P < 0.05 ). Fish subjected to two-time stress (2Stresses) had a higher survival rate after AC stress (90.63% vs. 62.50%), hematocrit, white blood cell, blood performance, total protein, high-density lipoproteins, cholesterol, triglyceride, alternative complement activity (ACH50), superoxide dismutase, glutathione peroxidase, and alkaline phosphatase levels than those not stressed ( P < 0.05 ). Contrariwise, glucose, cortisol, alanine aminotransferase, and aspartate aminotransferase levels were significantly lower in the 2Stresses groups compared with 0Stress fish ( P < 0.05 ). Collectively, these findings suggest stressing the signs of adaptation in 2Stresses fish. However, a higher number of early stress events (4Stresses) appears to exceed the threshold of manageable stress levels for this species. In conclusion, the HL2Stresses group outperformed the other treatments in terms of growth, health status, and stress responsiveness. Although fish welfare must be considered, these results suggest that early mild stress can result in a greater survival rate after fish are exposed to later acute stress.

“…These herbs can promote the performance of hens and improve antioxidant capacity and flesh quality; and stimulate digestive enzymes, appetite, and the immune system [6]. In our previous studies, we observed the positive effects of garlic (Allium sativum) [7,8], barberry (Berberis vulgaris) [9,10], figwort (Scrophularia striata) [11] and dill (Anethum graveolens) [12] on animal growth and health. In chicken, among a long list of herbs, garlic, ginger (Zingiber officinale), turmeric (Curcuma longa), and green tea (Camellia sinensis) have…”

Objective: This study investigated the effects of extruded flaxseed with and without herbs mixture on egg performance, yolk fatty acids (FAs), lipid components, blood biochemistry, serological enzymes, antioxidants and immune system of Hy-Line W-36 hens for nine weeks.Methods: Two hundred forty laying hens were randomly distributed to eight treatments, resulting in six replicates with five hens. Graded levels of dietary extruded flaxseed (0, 90, 180, and 270 g/kg) with and without herbs mixture (24 g/kg: garlic, ginger, green tea, and turmeric 6 g /kg each) were designed as treatments. Results:The two-way ANOVA indicated that hens fed herbs mixture had a higher value of egg production, yolk high-density lipoprotein, superoxide dismutase, glutathione peroxidase, and white blood cell and lower contents of yolk cholesterol, glucose, and blood low-density lipoprotein than those fed diets without herb mixtures (p<0.05). The Flx27 (270 g/kg flaxseed) (153.5 g/kg n-3 FAs) and Flx27+H (270 g/kg flaxseed plus 24 g/kg herbs mixture) (150.5 g/kg n-3 FAs) groups were the most promising treatments in terms of yolk n-3 FAs content. Interaction effect (herbs-flaxseed) for blood cholesterol, high- A c c e p t e d A r t i c l edensity lipoprotein (HDL), malondialdehyde, glutaredoxin, alanine transaminase (ALT), aspartate transaminase (AST), haemoglobin and immune parameters was significant (p<0.05). The results showed layers fed herbs mixture (Flx9+H, Flx18+H, and Flx27+H) had a better value of total antibody, immunoglobulin M, immunoglobulin G, ALT, AST, and blood HDL as compared with representative flaxseed levels without herbs. Conclusion:High inclusion levels of extruded flaxseed (270 g/kg) without herbs to enrich eggs with n-3 appears to impair the antioxidant system, immunohematological parameters, and serological enzymes.Interestingly, the herbs mixture supplementation corrected those effects. Therefore, feeding layers with flaxseed-rich diets (270 g/kg) and herbs mixture can be a promising strategy to enrich eggs with n-3 FAs.
