“…Por otro lado, algunos estudios muestran el impacto positivo en los parámetros productivos, integridad intestinal, respuesta inmune y microbiota intestinal (Emami et al, 2017;Polycarpo et al, 2017;Araujo et al, 2018;Nguyen et al, 2018;Adhikari et al, 2020;Al-Mutairi et al, 2020), beneficios que inicialmente han sido atribuidos al efecto que tienen sobre el ambiente del tracto gastrointestinal (TGI), en el proceso de digestión y como fuente de energía; pero principalmente como protección del mismo. Los AO se encuentran de manera natural en TGI de las aves; entre los que se incluyen ácido láctico en mayor proporción en el intestino delgado; mientras que los ácidos propiónico, acético y butírico se localizan mayormente en los sacos ciegos; esto es debido al proceso de fermentación (Meimandiopur et al, 2011;Khan e Iqbal, 2016;Rhot et al, 2017).…”

“…Sin embargo, la información no menciona los valores de pH. Otras investigaciones en pollos utilizaron una mezcla de ácidos orgánicos (ácido propiónico, ácido fórmico y ácido butírico), para acidificar el agua a un pH de 3 a 4.5; los resultados arrojaron beneficios en los parámetros productivos, microbiota intestinal, respuesta inmune, digestibilidad de nutrientes y calidad de la canal (Ghulam et al, 2013;Emami et al, 2017;Polycarpo et al, 2017;Araujo et al, 2018;Nguyen et al, 2018;Adhikari et al, 2020;Al-Mutairi et al, 2020 ); sin embargo, la literatura disponible sobre el uso de estos AO utilizados en el agua de bebida y dirigidos a demostrar sus beneficios sobre el desempeño zootécnico y pH intestinales, son escasos. El objetivo del presente trabajo fue evaluar el desempeño zootécnico del pollo de engorda, a la adición de una mezcla de AO en el agua de bebida durante su vida productiva; así como el pH digestivo y morfología del duodeno, pH sanguíneo, resistencia a la tracción del yeyuno y amarillamiento de la piel.…”

“…There have been mixed reports on the effects of probiotics on broiler performance. Some investigators have reported positive effects on bird performance (Palamidi et al 2016;De Cesare et al 2017;Pereira et al 2019), while others have not seen any significant probiotic effect (Olnood et al 2015b;de Souza et al 2018;Zarei et al 2018;Araujo et al 2019). Similar outcomes have been reported in humans, with investigators explaining that 'probiotics don't work for everyone,' and suggesting factors such as strain of probiotic organism, dose, route and period of administration, and health conditions of the host (Islam 2016), as being responsible for these discrepancies.…”

“…There is no doubt that feed additives and supplements such as probiotics, prebiotics, organic acids, and exogenous enzymes can modulate the intestinal microbial community of the host to promote health (Adeola and Cowieson 2011;Kim et al 2011;Teng and Kim 2018;Araujo et al 2019;Pereira et al 2019;Yadav and Jha 2019;Haberecht et al 2020) and are especially recommended for use in poultry to build or reestablish normal flora during periods of stress and other challenges that cause immunosuppression.…”

The use of probiotics in poultry production has increased rapidly, and this movement has been promoted by global events, such as the prohibition or decline in the use of antibiotic growth promotants in poultry feeds. There has been a persistent search for alternative feed additives, and probiotics have shown that they can restore the composition of the gut microbiota, and produce health benefits to the host, including improvements in performance. Probiotics have shown potential to increase productivity in poultry, especially in flocks challenged by stressors. However, the outcomes of probiotic use have not always been consistent. There is an increasing demand for well defined products that can be applied strategically, and currently, probiotic research is focusing on delineating their mechanisms of action in the gut that contribute to an improved efficacy. In particular, mechanisms involved in the maintenance and protection of intestinal barrier integrity and the role of the gut microbiota are being extensively investigated. It has been shown that probiotics modulate intestinal immune pathways both directly and through interactions with the gut microbiota. These interactions are key to maintaining gut homeostasis and function, and improving feed efficiency. Research has demonstrated that probiotics execute their effects through multiple mechanisms. The present review describes recent advances in probiotic use in poultry. It focuses on the current understanding of gut homeostasis and gut health in chickens, and how it can be assessed and improved through supplementation of poultry diets with probiotics in poultry diets. In particular, cellular and molecular mechanisms involved in the maintenance and protection of gut barrier structure and function are described. It also highlights important factors that influence probiotic efficacy and bird performance.

“…There have been mixed reports on the effects of probiotics on performance indices when fed to broiler chicks. Some investigators have reported positive effects on bird performance ( Patel et al., 2015 ; Palamidi et al., 2016 ; De Cesare et al., 2017 ; Pereira et al., 2019 ), whereas others have not seen any significant effect of specific probiotics ( Olnood et al., 2015 ; De Souza et al., 2018 ; Zarei et al., 2018 ; Araujo et al., 2019 ). The addition of H57 to the diet of challenged birds (NE-H57 birds) from day 0 to day 21 ameliorated the damaging effects of NE on gut mucosa.…”

Probiotic Bacillus amyloliquefaciens H57 ameliorates subclinical necrotic enteritis in broiler chicks by maintaining intestinal mucosal integrity and improving feed efficiency

Subclinical necrotic enteritis ( NE ) was induced in broiler chicks using a high dose of Eimeria spp. vaccine in the drinking water on day 9, and Clostridium perfringens ( Cp ) culture mixed in the feed on days 14 and 15. The aim was to evaluate the effects of probiotic Bacillus amyloliquefaciens strain H57 ( H57 ) in preventing NE in chicks. Day-old Ross 308, male broilers were weighed and randomly assigned to 6 treatment groups (6 replicate cages/treatment and 8 birds/cage). Birds in group 1 (control) were fed the basal wheat-soybean diet without H57 or NE infection; in group 2 ( Eimeria ) were treated with Eimeria alone; in group 3 ( Cp ) were treated with Cp alone; in group 4 (NE) received both Eimeria and Cp ; in group 5 (NE-H57) received NE infection and H57; and group 6 (H57) received H57. The basal diet of chicks in groups 5 and 6 was supplemented with H57 at a density of 2 × 10 8 spores/g feed from 1 D of age. On day 21, there were no significant treatment effects on BW and feed intake between control and H57 birds. However, on day 21, the feed conversion ratio of NE-H57 birds was significantly improved when compared with NE birds (1.28 vs. 1.36; P < 0.001). Birds challenged with NE had a higher occurrence of pasty vent than birds infected with either Eimeria , Cp , or NE-H57 (41 vs. 27 vs. 29 vs. 19%, respectively; P < 0.001). Intestinal lesion scores of NE birds were also higher than those of Eimeria , Cp , and NE-H57 birds (5.67 vs. 2.56 vs. 2.78 vs. 2.10, respectively; P < 0.001) and correlated with pasty vent (Pearson's r = 0.56; P < 0.001). Microscopic evaluation showed mucosal damage and necrosis in NE birds. In contrast, villi from NE-H57 birds were normal, with no damage or infiltration with Eimeria or Cp . H57 appears to be effective in challenged birds, as it maintained epithelial barrier integrity and improved feed efficiency.
