Alternatives to antibiotics for organic poultry production: types, modes of action and impacts on bird's health and production

Incidence of gastrointestinal parasites in pigeons with an assessment of the nematocidal activity of chitosan nanoparticles against Ascaridia columbae

“…To overcome and control microbial infections and parasitism, many approaches could be applied such as; using biological control ( Hegazy et al., 2022 ), application of antiparasitic chemical drugs ( Attia et al, 2022 ; Soliman et al., 2022 ), or using natural plant extract ( Abd El-Hack et al, 2021 , 2022 , 2022a ; El-Saadony et al, 2022 ; Saad et al, 2022 ).…”

Parasitological and histopathological examination of Cocktail lovebirds infected with Eimeria aratinga (Apicomplexa: Eimeriidae)

“…Birds are an integral part of virtually every ecosystem, and it is not surprising that they are commonly found in households and zoos worldwide ( Attia and Salem, 2022 ; Cocumelli et al, 2021 ). Many serious pathogens can infect avian spp., including bacteria ( Abd El Hamid et al, 2019 ; Marouf et al, 2020 , Marouf et al., 2022 ), viruses ( Setta et al, 2018 ), parasites, and fungi, as well as environmental and management stressors, revealing in severe economic losses ( Abd El-Hack et al, 2021a , b ; 2022b ). However, there is much literature on avian medicine, including parasitic diseases ( Olsen and Orosz, 2000 ).…”

“…Many treatment strategies are abundant among avian species, including antibiotics, chemical preparations, and anthelmintics. Still, recently the world has been directed to find new safe and environmentally friend products as herbal extract ( Abd El-Hack et al, 2022a ), bioactive plant compounds ( El-Saadony et al, 2021 ), natural pigments ( Ashour et al, 2021 ), polyphenols ( Ashour et al, 2020 ), organic acids ( Abd El-Hack et al, 2022b ), amino acids ( Abou-Kassem et al., 2022 ; Alagawany et al, 2021a ; Arif et al., 2022 ), probiotics, essential oils ( El-Tarabily et al, 2021 ; Alagawany et al, 2021b ; Abd El-Hack et al, 2022c ), nanomedicine ( Yousry et al, 2020 ; Salem et al, 2021 ), and vaccination strategies ( El-Naggar et al, 2022 ) to control such infections, and enhance birds’ performance. Therefore, this study aimed to identify the possible cause of such problem with the demonstration of postmortem and histopathological alterations in the affected tissues as well as, check the blood parameters of the infected birds.…”

Organic Egg Consumption: A Systematic Review of Aspects Related to Human Health

“…Specifically, it has been found in studies based on biochemical analyses of egg composition that, compared to conventional eggs, organic eggs are lower in saturated fat (conventional eggs: 85.7 g kg−1 yolk; organic eggs: 68.1 g kg−1 yolk) (20), have a lower n-6/n-3 ratio (conventional eggs: 11.5; organic eggs: 7.8) (20), and have fewer endocrine disruptors such as dimethyl phthalate (DMP) (conventional eggs: 76%; organic eggs: 52%) (33). In addition, other review studies reported that organic eggs are less exposed to antibiotics (34) and are less contaminated by Salmonella (35). These biological differences are supposed to be largely explained by animal feed based on feed made with mostly organic products and under extremely hygienic conditions (29,36).…”
