Effects of ginger extract and/or propolis extract on immune system parameters of vaccinated broilers. Poult Sci 2023; 102:102903. [PMID: 37506621 PMCID: PMC10413198 DOI: 10.1016/j.psj.2023.102903] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 06/18/2023] [Accepted: 06/24/2023] [Indexed: 07/30/2023] Open
Abstract
Newcastle disease (ND), avian influenza (AI, H5N8), and infectious bronchitis (IB) are important diseases in the poultry industry and cause significant losses. Vaccination is the most practical method for controlling infectious diseases. To reduce vaccination costs and several disorders in poultry farms, using herbal water supplements for immunomodulation with vaccination is critical to improving or preventing some conditions in the poultry industry. However, drinking water supplementation of ginger extract (GE)/propolis extract (PE) alone/in combination may increase broilers' humoral and cellular immunity due to the immunomodulatory effects of ginger and propolis. This protocol aimed to see how GE/PE alone or in combination improved the immunity, immune organ gene expression, and histology of the immune organs of broilers for 35 d after vaccination against NDV, H5N8, IBV, and IBDV. The chicks were dispensed into 5 groups according to GE and/or PE with vaccination. The control group was offered normal drinking water without any supplements or vaccinations. The GE group was supplemented with ginger extract (1 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The GE+PE group was supplemented with GE (0.5 mL/L drinking water) and PE (0.5 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The PE group was supplemented with propolis extract (1 mL/L drinking water) in the drinking water before and after vaccination for 2 and 3 d, respectively. The fifth group was the vaccinated untreated group. This experiment showed the immunomodulatory properties of GE and/or PE against 3 common diseases, NDV, AI, and IB, in broiler chicken farms for 35 d applied to a vaccination program. Thus, ginger extract and propolis extract supplementation in drinking water increased antibody titer, INF, IL10, and IL2 and TLR3 gene expression in the bursa of Fabricius, thymus, and spleen, respectively, as well as cellular immunity as indicated by increased CD3, CD4, and CD8 in the bursa of Fabricius, thymus, and spleen, respectively, with normal lymphocytes in the medulla of the bursa, thymus, and spleen. In conclusion, propolis extracts alone or with GE improved all of the metrics mentioned above without harming the histology of the immune organs.

Effects of Bee Pollen on Growth Performance, Intestinal Microbiota and Histomorphometry in African Catfish. Animals (Basel) 2022; 13:ani13010132. [PMID: 36611741 PMCID: PMC9817710 DOI: 10.3390/ani13010132] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 12/23/2022] [Accepted: 12/28/2022] [Indexed: 12/30/2022] Open
Abstract
This study aimed to determine the dietary effects of honeybee pollen (BP) on growth parameters, intestinal microbiota, hepatic histoarchitecture, and intestinal histomorphometry of African catfish Clarias gariepinus juveniles. The feeding experiment was carried out in a recirculating aquaculture system under controlled conditions for 21 days to achieve more than a 10-fold increase in weight in fish from the control group. Fish were fed well-balanced commercial feed without any supplements and served as a reference group (group C) and other diets enriched with varying BP levels as 1% (BP1), 2% (BP2), and 3% (BP3). Results showed a significant (p < 0.05) effect of the dietary BP not only on the growth parameters (such as final body weight: 5.0 g to 6.6−7.5 g, weight gain: 0.23 g/d to 0.31−0.35 g/d, body length: 84.7 mm to 93.8−95.9 mm, and specific growth rate: 11.7%/d to 13.1−13.7%/d, group C vs. experimental groups, respectively) but also on the development of beneficially important gut microbiota, such as lactic acid-producing bacteria. In BP-enriched groups, an average of 45% higher body weight gain was observed compared to those reared in the control group. The histological analysis showed that dietary BP may have a positive effect on the development of the intestinal tract and may enhance the absorption of nutrients with the potential ability to maintain a normal hepatic histoarchitecture of the treated African catfish. The results obtained suggest the optimum level of BP additive to feed for African catfish should be 1%.

The Application of Pollen as a Functional Food and Feed Ingredient-The Present and Perspectives. Biomolecules 2020; 10:biom10010084. [PMID: 31948037 PMCID: PMC7023195 DOI: 10.3390/biom10010084] [Citation(s) in RCA: 65] [Impact Index Per Article: 16.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 12/30/2019] [Accepted: 01/02/2020] [Indexed: 12/11/2022] Open
Abstract
Pollen is recognized as an excellent dietary supplement for human nutrition, which is why it can be found in different forms on the market (granules, capsules, tablets, pellets, and powders). But, the digestibility of pollen’s nutrients is strongly affected by the presence of a pollen shell, which can decrease the bioavailability of nutrients by 50% and more. Since consumers have become more aware of the benefits of a healthy diet and the necessity to improve pollen digestibility, different pollen-based functional food products have been developed and extensive studies were done to estimate the beneficial effects of pollen-based feed on animal growth, health, and rigor mortise stage. Considering the positive effects of pollen nutrients and phytometabolites on human and animal health, the aim of this paper was to give an overview of recent achievements in the application of pollen in the formulation of functional food and animal diets. Special attention was paid to the effects of pollen’s addition on the nutritional, functional, techno-functional, and sensory properties of the new formulated food products. Anti-nutritional properties of pollen were also discussed. This review points out the benefits of pollen addition to food and feed and the possible directions in the further development of functional food and feed for the wellbeing of everyone.

Grabek-Lejko D, Tomczyk-Ulanowska K. Phenolic content, antioxidant and antibacterial activity of selected natural sweeteners available on the Polish market. JOURNAL OF ENVIRONMENTAL SCIENCE AND HEALTH. PART. B, PESTICIDES, FOOD CONTAMINANTS, AND AGRICULTURAL WASTES 2013; 48:1089-1096.

Abstract
Seventeen natural sweeteners available on the Polish market were screened for total phenolic content, by the Folin-Ciocalteu method, and for antioxidant activity, using the ferric reducing antioxidant power (FRAP) assay and the 2,2'-Azinobis (3-ethylbenzthiazoline-6-sulphonic acid) radical cation decolorization assay (ABTS(·+)). In addition, we analyzed antibacterial activities against Staphylococcus aureus strains: both those susceptible and those resistant to methicillin (MRSA). The results of the study showed that total phenolic content, antioxidant activity and antibacterial activity differ widely among different samples of sweeteners. Phenolic content, expressed as a gallic acid equivalent, ranged from 0 mg kg(-1) in white, refined sugar, xylitol and wheat malt syrup to 11.4 g kg(-1) in sugarcane molasses. Antioxidant activity was lowest in refined white sugar, xylitol, brown beet sugar, liquid fructose, and rape honey; it was average in spelt syrup and corn syrup, and highest in sugar cane, beet molasses, date and barley syrups. Despite the great variety of sweeteners, a strong correlation was noted between the concentration of phenolics and antioxidant properties, as determined by the ABTS(·+) method (r = 0.97) and the FRAP assay (r = 0.77). The strongest antibacterial activity was observed in sugarcane molasses, which was lethal to S. aureus strains at 2 and 4% concentrations in medium for susceptible and MRSA strains respectively. Other sweeteners kill bacteria in 6-15% solutions, whereas some did not show any antibacterial activities against S. aureus strains, even at 20% concentrations. Due to their high antioxidant and antibacterial activities, some of the tested sweeteners have potential therapeutic value as supporting agents in antibiotic therapy.
