“…These active substances, that have medicinal property can be extracted and used in different forms to prevent or treat some diseases (SOFOWORA, 1996). In ovo feeding research has shown that vegetal extracts from plants such as Toussaintia patriciae, Eugenia jambolana and Guiera senegalensis, improved chicken immune status against infectious bursal virus, avian influenza virus (H5N1) and fowl poxvirus (NYANDORO et al, 2014, SOOD et al, 2012, LAMIEN et al, 2005. Moringa oleifera is also another promising tree with a good profile of important trace elements, good sources of proteins, vitamins and can be used as animal feed (ANWAR et al, 2007;DOUGNON et al, 2012;SULTANA et al, 2015).…”

Moringa oleifera in feed post-hatch improves growth in early postnatal life. One may question the effects of Moringa oleifera after in ovo feeding. This study was carried out to determine the effect of different time periods of in ovo inoculation of Moringa oleifera leaves (MOL) extract on hatchability and juvenile growth performance. For the experiment, a total of 868 fertile broiler eggs identified by candling were used. They were randomly allotted to 7 groups with 124 eggs per group. Three groups were used for MOL extract inoculation at d 16, 17 and 18 (M groups).Further three groups were used for saline solution inoculation at d 16, 17 and 18 as positive controls (T groups) for those used for MOL extract inoculation. A negative control (T0) received no inoculation at all. The results showed that in ovo inoculation of MOL extract on d 18 of incubation significantly increased hatchability and reduced late embryonic mortality rate and hatching curve. In addition, MOL extract injection improved the percentage of day-old chicks with high quality as well as the average chick quality score (P < 0.05). Furthermore, post-hatch growth up to 7 days of age showed that the chicks hatched from eggs inoculated with MOL extracts on d 18 of incubation had significantly higher body weight gain than those injected on other days. It can be concluded that in ovo inoculation of MOL extract on d 18 of incubation into the air chamber provided the best strategy to improve hatchability, chick quality and post hatch growth of broiler.

“…Data were obtained from the macroscopic image of CAM and the number of pock lesions was counted on the CAM of the ECEs in all groups [9,26]. Group VIII, a control for the herbal and herbal toxicity test, was used to determine the maximum non-toxic concentration of each extract concentration [8,9].…”

“…Mortality is usually low in birds with a mild cutaneous form of the disease; however, it becomes a significant problem with systemic infection when diphtheric lesions are dominant or when the disease is accompanied by other infections or poor environmental conditions [ 5 - 7 ]. Therapy for avian pox is not available; however, an alternative to control avian pox may lie in the use of medicinal plants [ 8 , 9 ].…”

In ovo inhibition of avian pox virus replication by mangosteen rind and red ginger ethanolic extracts

Background and Aim: Avian pox is a contagious disease caused by the avian pox virus (APV). Mangostin and γ-mangostin in mangosteen rind (MR) and gingerol in red ginger (RG) exhibit antiviral activity. In this study, we evaluated the effect of MR and RG ethanolic extracts on APV based on pock lesions on the chorioallantoic membrane (CAM) of specific pathogen-free (SPF) embryonated chicken eggs (ECEs). Materials and Methods: Three APVs from chicken isolates (C1, C2, and C3), one APV from a pigeon isolate (P), 1.5% and 3% MR ethanolic extract, 5% and 10% RG ethanolic extract, and a combination of 1.5% MR and 5% RG at 0.1 mL/ egg were inoculated in ovo (7th day incubation, chorioallantoic route) in SPF ECEs. A control group inoculated in ovo with APV alone was also established. Each treatment consisted of three replicates. Parameters including embryo survival, CAM lesions, and average number of pock lesions were determined. Results: In ovo inoculation of MR and RG ethanolic extracts was not harmful to the ECEs and did not induce CAM lesions. The average number of pock lesions in the control group (C1, C2, C3, and P) was 35, 14, 10, and 17, respectively, whereas in all treatment groups, the number was 0, except in the 5% RG group of C1, which had a value of 10. Conclusion: In ovo inoculation of 1.5% and 3% MR, 5% and 10% RG, and the combination of 1.5% MR plus 5% RG ethanolic extract s at 0.1 mL/egg inhibit APV by reducing the number of pock lesions on the CAM of the ECE.

“…Notably, methanolic extracts of different Sudanese medicinal plants were observed to exhibit antiviral activity against FWPV [57] as well as aqueous decoctions and acetone extracts of galls of Guiera senegalensis J. F. Gmel. (Combretaceae) in vitro, in ovo, and in vivo [58][59][60]. Treatments with an ethanolic extract of the root bark from Synadenium glaucescens Pax (Euphorbiaceae) demonstrated significantly higher mean embryo weight in an in ovo assay against FWPV compared with other extracts of the same plant [61].…”

Viruses have a high mutation rate, and, thus, there is a continual emergence of new antiviral-resistant strains. Therefore, it becomes imperative to explore and develop new antiviral compounds continually. The search for pharmacological substances of plant origin that are effective against animal viruses, which have a high mortality rate or cause large economic losses, has garnered interest in the last few decades. This systematic review compiles 130 plant species that exhibit antiviral activity on 37 different virus species causing serious diseases in animals. The kind of extract, fraction, or compound exhibiting the antiviral activity and the design of the trial were particularly considered for review. The literature revealed details regarding plant species exhibiting antiviral activities against pathogenic animal virus species of the following families–Herpesviridae, Orthomyxoviridae, Paramyxoviridae, Parvoviridae, Poxviridae, Nimaviridae, Coronaviridae, Reoviridae, and Rhabdoviridae–that cause infections, among others, in poultry, cattle, pigs, horses, shrimps, and fish. Overall, 30 plant species exhibited activity against various influenza viruses, most of them causing avian influenza. Furthermore, 30 plant species were noted to be active against Newcastle disease virus. In addition, regarding the pathogens most frequently investigated, this review provides a compilation of 20 plant species active against bovine herpesvirus, 16 against fowlpox virus, 12 against white spot syndrome virus in marine shrimps, and 10 against suide herpesvirus. Nevertheless, some plant extracts, particularly their compounds, are promising candidates for the development of new antiviral remedies, which are urgently required.
