Antioxidant and antimicrobial activities of Spirulina platensis extracts and biogenic selenium nanoparticles against selected pathogenic bacteria and fungi

“…The produced SeNPs were characterized using six advanced instruments. UV–Vis spectroscopy was used to estimate the optical property of the SeNPs mixture ( El-Saadony et al, 2020a , Saad et al, 2021a ). Fourier Transform-Infrared (FT-IR) spectroscopy (“Bruker Tensor 37, Kaller”, Germany) was used to identify the potential active compounds in the SeNPs mixture ( Beekes et al, 2007 , El-Saadony et al, 2021b ).…”

Hot red pepper powder as a safe alternative to antibiotics in organic poultry feed: an updated review

“…Biologically active constituents and properties of HRP are summarized in Figure 1 and Table 1 . Phytogenics are a heterogeneous group of feed additives of plant origin consisting of herbs, spices, fruit, and other plant parts ( Gheisar and Kim, 2018 ; Ashour et al, 2020 ; Reda et al, 2021b ; Saad et al, 2021b , c ). The applications of spices and herbs (phytobiotics) in broiler nutrition were previously studied ( Horosova et al, 2006 ; Cross et al, 2007 ; Al-Kassie et al, 2011a , 2012 ; Kostadinović and Levic, 2012 ; Puvača et al, 2013 , 2014 , 2015a , b ).…”

Necrotic enteritis in broiler chickens: disease characteristics and prevention using organic antibiotic alternatives – a comprehensive review

“…Antibiotics effectively repress and inhibit microorganisms until antibiotic-resistant bacteria appear. The tendency to use alternative eco-friendly compounds solves this problem ( Abd El-Hack et al, 2020b , c ; Abo Ghanima et al, 2021 ; Dosoky et al, 2021 ; Mohamed et al, 2021 ), such as phenolic compounds in herbal extracts ( El-Saadony et al, 2021a ; Saad et al, 2021a , b ), prebiotics ( Abd El‐Hack et al, 2021a , b , c ; Yaqoob et al, 2021 ), probiotics ( Abd El-Hack et al, 2020b ; Alagawany et al, 2021a ; El-Saadony et al, 2021b , c ), essential oils ( Alagawany et al, 2021b ; El-Tarabily et al, 2021 ), various plant extracts ( El-Saadony et al, 2021b ), phytogenic feed additives ( Abdelnour et al, 2020a , b ; Ashour et al, 2021 ; Raza et al, 2021 ; Seidavi et al, 2021a , b ), hen egg antibodies ( Wilkie et al, 2006 ), feed enzymes ( Llamas-Moya et al, 2020 ), vaccination ( Kulkarni et al, 2007 ), diet formulation with ingredient selection, cereal type, feed processing, and dietary protein source level ( Caly et al, 2015 ).…”
