Microbial, immune and antioxidant responses of Nile tilapia with dietary nano-curcumin supplements under chronic low temperatures

A 56-day feeding period was performed to investigate the possible impacts of dietary nano curcumin (0, 50, 100, 150, and 200 ppm) on the growth, nutrient utilization, non-specific immune parameters, antioxidants in Nile tilapia under chronic low temperature (21.02 ± 0.11 °C). Fishes (n = 225; Initial weight = 4.39 ± 0.08 g/fish) were randomly stocked at 15 fish/tank for five experimental groups in triplicates. Under low-temperature circumstances, dietary curcumin in nano form showed no notable alteration in growth variable, nutrient efficiency, digestive enzymes efficiency, biometric indices, survival rates, and hematological components. Meanwhile, the serum of fishes with nano curcumin diets under low-temperature stress displayed higher total protein as well as lower glucose, cortisol, and total cholesterol compared with the control group. Moreover, fish fed nano curcumin diets displayed higher lysozyme and …

Genetic evaluation for milk and semen variables on Egyptian buffaloes

2584 lactation records of Egyptian buffaloes calving between1992 to 2010 kept at Natafe El Gadded farm were studied. Several variables Animal model (SVAM) was used. Milk variables are milk production (MP), days in milk (DM), and calving interval (CI) and semen quality are ejaculate volume (EV) life of sperm (LS) and total Motility (TM). The overall means of MP, LL, CI, EV, LS, and TM were 2025 kg, 203 d, 447 d, 3.25 ml, 65.91% and 58.40%, respectively. Heritabilities were 0.23, 0.13, 0.02, 0.08, 0.27 and 0.24, for milk production, lactation length, current calving interval, ejaculate volume, live of sperm and total motility, respectively. Genetic association among MP and each of DM and CI were positive and were 0.80, 0.04, respectively, while among DM and CI was negative (-0.54). Genetic association among EV and each of LS and TM were. 04 and-0.03, respectively, while among LS and TM was (1.0). In conclusion, our findings provide useful information on the heritability of milk production, life of sperm and mass motility traits in Egyptian buffaloes and relationships among them and should assist in selection for improvement of milk yield and semen traits in Egyptian buffaloes and bulls.

Toxicity and therapeutical impacts of Bee venom (Apis mellifera L.) on Nile tilapia juvenile (Oreochromis niloticus)

Bee venom (BV) has been widely studied for its therapeutic properties in various medical applications. However, its effects on aquatic organisms, particularly Nile tilapia (Oreochromis niloticus), remain poorly understood, particularly concerning toxicity and therapeutic impacts. This study investigated the effects of bee venom (BV) injection on Nile tilapia (O. niloticus) by examining growth, feed efficiency, biometric parameters, whole-body chemical analysis, and the activity of antioxidant enzymes in the liver. Nile tilapia juveniles were injected with BV at doses of 0, 3, 6, 9, and 12 mg/kg of fish weight. Observations were made on the 14th day post-injection (DPI). No significant differences were found in growth, feed utilization, survival rate, biometric indices, and whole-body composition among the BV dosage groups. Similarly, the activity of intestinal enzymes (amylase, protease, and lipase) showed no significant …

Effect of dietary sage (Salvia officinalis L.) on the growth performance, feed efficacy, blood indices, non-specific immunity, and intestinal microbiota of European sea bass …

Adding medicinal herbs to aquafeed is recommended for feasible aquaculture activity. This study tested for 90 days the effect of dietary sage (Salvia officinalis L.) on the growth performance, feed efficacy, blood indices, non-specific immunity, and intestinal microbiota of European sea bass (Dicentrarchus labrax; n = 300 fish). Fish with an initial weight of 12 ± 0.1 g/fish were distributed in five treatments and fed sage at 0, 2, 4, 6, and 8 g/kg. Dietary sage at 2 g/kg diet improved the growth, feed consumption, and growth hormone secretion in European sea bass. The blood parameters in European sea bass fed on experimental diets showed normal levels for healthy fish. Significantly higher lysozyme and phagocytic activities were recorded with sage supplement at the 4 g/kg diet compared to other groups. Regarding overall bacterial count, fish given a sage-free diet (the control) showed more significant microbiota …

Administration of bee pollen, Nigella sativa oil, and their combination as a strategy for improving growth performance, immunity, and health status of newborn friesian calves …

This study aimed to evaluate the effect of dietary supplementation of bee pollen (BP), black seed oil (BS, Nigella sativa), or their comb ination on growth performance, immunity, and health status of females of newborn Friesian calves. A total of 20 newborn calves (37.51±0.92 kg LBW) were divided into 4 groups. During the suckling period, animals in the 1 st group were fed a starter without any addition (G1, control). Animals in G2, G3, and G4 were fed the same starter supplemented with BP (10g/kg), BS oil (10g/kg), or their combination (5g Bp+ 5g BS oil), respectively. Results showed that all immunoglobulin types (IgG, IgM, and IgA), total protein, albumin, globulin, glucose, total lipids, total cholesterol, and total antioxidant capacity in blood serum, and RBCs, WBCs, Hb, and PCV increased (P< 0.05) in treated than in the control calves, being the highest with the combination treatment. Urea-N and creatinine concentrations, and AST and ALT activities decreased (P< 0.05) in treated compared with the control calves, with the lowest values for the combination treatment. The treated calves were heavier with higher weight gains than the control one, being the highest with the combination treatment. In conclusion, addition of a combination of 5g bee pollen and 5g black seeds oil/kg in the starter during the sucking period improves live body weight, weight gain, immunity, kidney and liver functions, and antioxidant status of female newborn Friesian calves. This administration is considered a good strategy for raising dairy calves in dairy farms.

Growth performance, immunity, and general health status of newborn friesian calves fed milk supplemented with propolis, thyme, or their combination, as antioxidants, during the …

Aim of the resent study was to determine impacts of feeding milk supplemented with propolis thyme, or both, as antioxidants, on growth efficiency, liver function, kidney function, total antioxidant capacity, and immune response of Friesian calves from 7 to 105 days of age as an experimental period. Newborn male calves (n= 20) weighing 37.92±0.63 kg were divided into 4 groups, five calves/group. The first group (G1, control) included animals without treatment. During the whole suckling period each animal in G2, G3, and G4 daily received milk supplemented with propolis (5 g), thyme oil (2 ml), or 5 g propolis plus 2 ml thyme oil, respectively. Results showed that animals in fed both propolis and thyme combination showed the highest LBW, total gain, counts and percentages of blood cells, hemoglobin, total proteins and their fractions, total lipids, total cholesterol, and glucose, and the lowest urea and creatinine levels (P< 0.05). Plasma immunoglobulins (IgG, IgA, and IgM) and total antioxidant capacity increased to the maximal values, while AST and ALT activities decreased to the minimum values in G4. Feeding Friesian calves on milk supplied with propolis (5 g) plus thyme oil (2 ml) per calf during the suckling period can improve growth performance, general health status, immune response, and total antioxidant capacity. From an economical point of view, this treatment could increase profits by reducing morbidity, diarrhea cases, and mortality, and improving the performance of breeding male calves during suckling and the early post-weaning period.

Effect of marjoram (majorana hortensis) leaves supplementation on the growth performance and body composition of common carp, cyprinus carpio fries

An investigation was conducted to evaluate the effect of dietary different levels of (0, 2.5, 5 and 10 g/kg) marjoram leaves supplementation for common carp (Cyprinus carpio) fries. 420 fries (averaged 0.34±0.1 g) were randomly distributed into four treatments, three replicates in 12 aquaria and fed experimental diets four times per day. Results revealed that marjoram leaves as feed additives in the diets for common carp fries did affect the growth performance parameters with significant differences (P<0.05) among all dietary treatments. A decreasing trend was observed when the inclusion of marjoram leaves in the diets increased. Fish fed M1 (2.5 g/kg) diet showed the best FCR and significantly differed (P<0.05) among all dietary treatments. No significant differences were observed in the survival of fish fed the examined diets and fish fed M3 diet gained the highest value (96.2%). Also, significant differences (P<0.05) were observed in the protein content of fish body and fish fed M3 diet gained the highest value. Also, the lipid content was similar among all treatments. However, the inclusion of marjoram leaves in the experimental diets did not significantly (P>0.05) affect the condition factor (K), gonadosomatic (GSI), and hepatosomatic (HSI). Moreover, significant differences (P<0.05) were observed in viscerasomatic (VSI) indices values among all treatments. No diet-related histopathological changes were noted in all examined tissues such as liver, intestine and gonads of common carp fries.  The normality of all examined fish tissues indicated that marjoram leaves are safe to use in fish diets and can be added at 2.5 g/kg diet to improve the …

Effect of Probax, thyme extract, and their combination on growth performance, rumen function, and blood parameters of Friesian calves

This study aimed to examine the effect of Probax (Lactobacillus acidophilus), thyme (Thymus vulgaris) extract (THM), and their combination on productive performance, rumen function, hematological and blood biochemical components, and immunity of newborn Friesian calves from calving to weaning (105 d) and post-weaning (150 d of age). Total of 20 male Friesian calves at three days of age and 35.07±0.56 kg body weight were allotted into four groups (5 calves/group). In the 1st group (G1), calves were fed whole cow milk and the starter plus berseem hay after 7 days of age (control). Calves were fed the same control diet supplemented with 50 mg Probax /kg BW (G2), 40 mg of THM/kg BW (G3), and 50 mg of Probax and 40 mg of THM (G4). Growth performance parameters, ruminal VFAs concentration, protozoal count, RBCs, Hb, PCV, and concentration of total proteins, albumin, globulin, glucose, urea, total cholesterol, triglycerides, IgG, IgM, and IgA in blood serum were the highest (P˂0.05), while creatinine concentration, and AST and ALT activities were the lowest in G4. Dietary supplementation of Probax+THM (50 and 40 mg/kg BW) improved growth performance, rumen function, hematology, blood biochemicals, and immunity of Friesian calves at weaning, and at 150 days of age.

NUTRITIONAL STUDIES ON SOME FRESH WATER FISHES

This study was conducted in the Fish laboratory at Poultry and Fish Department, Faculty of Agriculture, Menoufia University. It was consisted of two experiments to evaluate the effect of some feed additives in the diets for mono-sex Nile Tilapia and common carp fries. The obtained results showed that the supplementation of zeolite at 10 g/kg diet improved the growth and feed utilization. The minerals composition of fish feces indicated that Fe in feces increased by increasing the dietary zeolite and it was excreted and did not accumulate in the fish body. However, the inclusion of marjoram leaves in the diets for common carp fries had a positive effect on the growth performance and the best addition was 2.5 g/kg diet. No diet-related histopathological changes were noted in all examined tissues of the fish among all treatments in both experiments.

IMMUNITY RESPONSE AND REPRODUCTIVE PERFORMANCE OF‎ LACTATING FRIESIAN COWS TREATED WITH BENTONITE

This study was conducted to determine the effect of dietary supplementation of bentonite on the immune status and reproductive performance of lactating Friesian cows. A total of 30 pregnant Friesian cows (4-6 years of age) were divided into three groups (10 cows in each). In the 1st group; G1, animals were fed the control diet, while those in the 2nd; G2 and 3rd; G3 groups were fed the control diet supplemented with 20 or 40 g bentonite/kg concentrate, respectively, from 60 days prepartum up to 120 days postpartum. Blood samples were taken at estrus and 120-d postpartum. Results show that calf weight at calving and placental drop time improved (P<0.05) in G3, while uterine horn symmetry and cervical closer improved in G2 and G3 compared with G1. Plasma immunoglobulins (IgG, IgM, and IgA) increased (P<0.05) in G3 than in G1 and G2. Count of RBCs and WBCs, hemoglobin, and PCV improved (P<0.05) by both treatments, being the highest (P<0.05) in G3. Interval to first estrus, service period, and days open were the best (P<0.05) in G3. Concentration of P4 was the lowest at estrus, and the highest at 120-d postpartum in G3. Number of services/conception and pregnancy rate were 1.4 and 50% in G1, 1.6 and 80% in G2, and 1.4 and 100% in G3.

Dietary coenzyme Q10 (CoQ10) and vitamin C (Vc) are natural immunostimulants and antioxidants involved in improving the performances and health conditions of aquatic animals. In this context, six diets were formulated and supplemented with CoQ10 and Vc at 0/0 (D1), 0/400 (D2), 0/600 (D3), 20/0 (D4), 20/400 (D5) and 20/600 (D6) mg of CoQ10/Vc per kg diet and fed to Nile tilapia for 56 days. The obtained results displayed higher weight gain, specific growth rate, and feed efficiency ratio in all groups than the control group (D1). Concurrently, feed intake, amylase, lipase, and protease activities were significantly higher in D5 and D6 groups than the other groups (P < 0.05). Conversely, the whole-body crude lipid content was markedly decreased with dietary CoQ10 or/and Vc, and the highest value was in fish fed D1 (P < 0.05). Interestingly, fish fed on D5 and D6 diets exhibited the lowest glucose, cortisol, total …
