“…La suplementación con probiótico o prebiótico, solos o combinados, no incrementó significativamente el consumo de alimento, mientras que la suplementación con APC redujo significativamente el consumo con respecto al control (p<0.05); sin embargo, es posible que esto sea un artefacto debido al cambio de olor o sabor del afrechillo de trigo por la adición del APC. Reducciones significativas en el consumo han sido observadas al incrementar la concentración de Znbacitracina en la ración de pollos de engorde (Reis et al, 2014). Barros et al (2008) tampoco encontraron incrementos significativos en el consumo de alimento en lechones suplementados con probiótico, prebiótico y simbiótico en comparación con el grupo control.…”

Efecto de la inclusión de probiótico, prebiótico y simbiótico en la dieta sobre los parámetros productivos del cuy (Cavia porcellus) Effect of dietary probiotic, prebiotic and their combination on the productive performance of guinea pigs (Cavia porcellus) RESUMENEl presente estudio evaluó el efecto de la inclusión de probiótico, prebiótico y la combinación de ambos (simbiótico) en la dieta sobre los parámetros productivos del cuy (Cavia porcellus). Se seleccionaron 50 cuyes machos de 3 días de edad de una línea materna Prolífica-Lechera desarrollada en la Estación IVITA-El Mantaro (Perú) y fueron distribuidos aleatoriamente en cinco tratamientos consistentes en una dieta basal de forrajes (rye-grass y trébol rojo) complementada con afrechillo de trigo (T5), más probiótico (T1), prebiótico (T2), simbiótico (T3) y antibiótico promotor del crecimiento (APC) (T4). El probiótico fue un consorcio de seis especies bacterianas aisladas del intestino y heces de cuy; el prebiótico fue un mananoligosacárido comercial y el APC fue Zn-bacitracina. La respuesta a los tratamientos fue evaluada por 56 días en términos de ganancia de peso, consumo de alimento y conversión alimenticia. No se observaron respuestas significativas ni consistentes por efecto de los tratamientos. La falta de respuesta al APC y las buenas ganancias de peso obtenidas sugieren que, bajo las condiciones del estudio, el balance microbiano intestinal de los animales era apropiado.

“…Many additives, including growth promoters, are periodically used to control the proliferation of pathogens in the intestinal segment of birds. However, the use of antimicrobials in animal feed has been restricted in several countries in recent years because they present the possibility of selecting resistant microorganisms and antibiotic resistance by pathogenic bacteria to humans, becoming an obstacle to commercialize meat in domestic and foreign trade (Reis et al 2014). Thus, research has been intensified for alternatives which may replace antimicrobial additives in order to eliminate the risks, especially to human health.…”

The objective of this study was to evaluate the replacement of a growth-promoting antibiotic by fennel (Foeniculum vulgare) and citronella (Cymbopogon winterianus) essential oils in the quail diet on performance variables (weight gain, feed intake, feed conversion), as well as the carcass and cut yield. To do so, 240 one-day-old male and female European quails were distributed in a completely randomized design with four treatments, five replications and 12 animals per experimental unit. The treatments consisted of: PC – positive control diet without fennel or citronella essential oils and with the growth promoter (zinc bacitracin); NC – negative control diet without essential oils and without growth promoter; CEO - Diet with +0.078% citronella essential oil without the growth promoter; and FEO - Diet with +0.078% fennel essential oil without the growth promoter. The experiment lasted 42 days, in which the performance variables were analyzed in three periods (1-14 days; 14-21 days; and 22-42 days) and the carcass and cut yield in two periods (at 21 and 42 days). The observed data were submitted to analysis of variance and the comparison of means was performed using the Tukey’s test at 5% significance. The presence of essential oils positively influenced (P<0.05) the performance variables and the carcass and cuts yield in all analyzed periods. The use of fennel and citronella essential oils to replace zinc bacitracin in the diet of European quails improves performance and the carcass and cut yield.

“…The poultry industry is affected with C. perfringens that causes necrotic enteritis in chickens which is a disease of increasing importance to the poultry industry, resulting in a total cost worldwide of more than $6 billion per year due to disease outbreaks ( Wade et al, 2015 ). Bacitracin is one of the most common antimicrobial agents used to control this bacterial enteric avian disease and has also been used as a performance enhancer in poultry in several countries ( Reis et al, 2014 ; Han et al, 2015 ). However, the extensive use of bacitracin appears to have led to the isolation of bacitracin-resistant C. perfringens strain ( Charlebois et al, 2012 ).…”

Antimicrobial and Synergistic Activity of 2,2′,4-Trihydroxybenzophenone Against Bacterial Pathogens of Poultry

et al. 2019

In poultry farming, the spread of bacterial pathogens results in disease outbreaks causing significant economic losses to this industry. Many of these pathogenic bacteria are zoonotic and have a substantial impact on public health. Antimicrobials are essential for the prevention and treatment of these bacterial infections. However, the indiscriminate use of these agents provides favorable conditions for selection, propagation and persistence of bacteria and development of antimicrobial resistance. We developed a new antimicrobial candidate that could be used alone or in synergy with research protocols for therapeutic, prophylactic and growth promoter uses in the poultry industry. The present study aimed at evaluating the antimicrobial activity of the synthetic compound 2,2′,4-trihydroxybenzophenone against pathogenic bacteria that cause important diseases in poultry and public health. We tested the hemolytic effect of this compound, studied its synergistic effect with conventional antimicrobials and analyzed the site of action on the bacteria. The results of our study showed antimicrobial activity of benzophenone against Gram-positive and Gram-negative bacteria with a similar effect in ATCC (American type culture collection) and field isolates. This compound was non-hemolytic. 2,2′,4-trihydroxybenzophenone acted on the bacterial cell wall. We identified the synergistic effect between 2,2′,4-trihydroxybenzophenone and bacitracin, this effect indicate that antimicrobial synergism may be useful for the treatment of necrotic enteritis in poultry. This compound may also be used as a growth promoter by reducing the dose of bacitracin and thus decreasing the pressure of bacterial resistance in poultry which would circumvent the development of cross-resistance in humans.
