Influence of dietary probiotic inclusion on growth performance, blood parameters, and intestinal microflora of male broiler chickens exposed to posthatch holding time

Utility of Feed Enzymes and Yeast Derivatives in Ameliorating Deleterious Effects of Coccidiosis on Intestinal Health and Function in Broiler Chickens

“…However, in general, most commercial probiotic feed additives for poultry are of bacterial preparations e.g., (49)(50)(51)(52)(53). The few non-bacterial (yeast or fungal) probiotics includes Aspergillus oryzae (54,55), Candida pintolopesii (54), Candida saitoana, Saccharomyces bourlardii (56), and S. cerevisiae (57). Arguably, yeast-based probiotics are indispensable in ruminant nutrition for their effectiveness in modulating rumen microbiome (58,59).…”

“…There are limited studies on yeast probiotic (e.g., S. boulardii) supplementation in broilers (111,112). The common approach is a blend of yeast probiotics with bacterial cultures on the premise that beneficial effects of probiotics are genus, species and strain specific and use of multi-strain and multi-species might be more effective than mono-strain probiotics (54,55). Indeed, some investigations have shown that co-supplementing yeast and bacterial probiotics enhanced their survival and growth (113,114).…”

“…bulgaricus, L. acidophilus, Lactobacillus rhamnosus, Bifidobacterium bifidum, Streptococcus salivarius ssp. thermophilus, Enterococcus faecium, A. oryzae, and Candida pintolepesii) did not ameliorate negative effects of delayed feed access in newly hatched chicks on growth performance and gastrointestinal physiology (54). A challenge of evaluating studies of probiotic blends is that experimental design does not always incorporate single strains to characterize responses of each strain vs. combination.…”

Probióticos y su mecanismo de acción en alimentación animal

“…Los géneros Lactobacillus y Bifidobacterium producen ácidos orgánicos como ácido láctico y acético, que pueden ser tomados por otras bacterias, entre ellas patógenas, en el tubo digestivo, reducen su pH intracelular a niveles letales (Daskiran et al, 2012). Estos ácidos orgánicos, además pueden contribuir a la disminución del pH en el tubo digestivo, creando condiciones favorables para la microbiota existente y disminuyendo el riesgo de ser colonizado por microorganismos patógenos (Chaucheyras-Durand y Durand, 2010).…”

Desarrollo de una mezcla microbiana para la inclusión como probiótico en la industria avícola: estudio de su acción sobre hongos contaminantes y micotoxinas

“…Los antibióticos se han incorporado como promotores de crecimiento en alimentos para pollos de engorde durante los últimos 40 años. La microbiota gastrointestinal de pollos de engorde sanos puede mantenerse estable mediante el uso de antibióticos en dosis preventivas (Daşkiran et al 2012;Zulkifli et al 2000),…”
