“…The results of the present experiment are in agreement with the findings by Flemming & Freitas (2005), who also evaluated the prebiotic Bacillus subtilis and obtained better broiler performance with the diets with that probiotic as compared to the diet without promoters.…”

“…The results of the present study are consistent with the findings by Flemming & Freitas (2005), Cardozo (2006), and Da Silva (2008), who also tested a probiotic composed of Bacillus subtilis, and concluded that birds submitted to the diet without promoters presented the worst feed conversion ratio. Conversely, Corrêa et al (2003) and Lorençon et al (2007) showed that the performance of broilers in the starter phase was not affected by the use of probiotics or antibiotics.…”

“…These compounds may improve animal performance by excluding microorganisms which compete with them for food nutrients in the gastrointestinal tract (Macari & Furlan, 2005), and by favoring the microorganisms considered as beneficial (Flemming & Freitas, 2005). However, the indiscriminate use of antibiotic growth promoters (AGP) led to emergence of resistance in pathogenic bacteria, and as result, the European Union has banned the addition of several antibiotics in broiler feeds since 2006, and other countries should follow this trend soon (Palermo, 2006).…”

-This work was carried out to evaluate the use of Bacillus subtilis probiotic C-3102 (10 10 cfu/g) in diets with or without growth promoters on the performance of broilers in the period from 1 to 42 days of age. It was used 1,200 Cobb line broilers, distributed in a complete randomized block with five diets: negative controller (without promoters);Bacillus subtilis (30 g/t ration); Bacillus subtilis (50 g/t ration); Bacillus subtilis (30 g/t ration) + colistin (10 ppm); avilamycin (10 ppm) + colistin (10 ppm). Each diet was evaluated in 10 repetitions with 24 birds. From 21 to 42 days of age, feed intake, weight gain and feed conversion were evaluated, and at 42 days of age, productive efficiency index was evaluated. At the end of the experimental period, it was observed an increase in the consumption of diet with the lowest dose of Bacillus subtilis

“…Similar results were found by Flemming and Freitas (2005) who did not observe difference in feed conversion among the additives, when testing an association of probiotics (Bacillus subtilis and Bacillus licheniformis) in comparison to the antibiotic avilamycin. However, when comparing them with the treatment without additive (control) there was a greater weight gain of those.…”

ABSTRACT. An experiment was carried out with female broilers, aiming to evaluate the effect of using probiotics and symbiotics on growth performance and yield of carcasses and of the main commercial cuts and edible viscera. A total of 720 one-day-old Cobb chicks, distributed in a completely randomized experimental design with four treatments and six replicates of 30 birds each at a stocking density of 10 birds per square meter (m 2 ). At 42 days old two broilers of each experimental unit were sacrificed to evaluate the carcass yield and its parts. The carcass yield was not affected by the inclusion of probiotics and symbiotics in the diet being equivalent to the antibiotic group. No significant difference was observed among the treatments, even in the controls that did not receive any additive factor. All the performance parameters were similar for the four treatments, with the exception of weight gain, that was significantly lower in probiotic treatment. It was concluded that these additives are important alternative to replace antibiotics as growth enhancers, which have already been banned in many countries.Keywords: poultry farming; additions; performance.Desempenho e rendimento de carcaças de frangos de corte fêmeas alimentados com dietas contendo probióticos e simbióticos como alternativa aos melhoradores de crescimento RESUMO. Foi realizado um experimento com frangos de corte fêmeas, objetivando-se avaliar o efeito da utilização de probióticos e simbióticos sobre o desempenho e rendimento de carcaça e dos principais cortes comerciais e vísceras comestíveis destes animais. Foram utilizados 720 pintos de um dia de idade da linhagem Cobb, distribuídos em um delineamento experimental inteiramente casualizado, com quatro tratamentos e seis repetições de 30 aves cada em uma densidade de 10 aves/metro quadrado (m 2 ). Aos 42 dias de idade foram abatidos dois frangos por repetição, para a avaliação do rendimento de carcaça e suas partes. A inclusão de probióticos e simbióticos na ração não proporcionou diferença significativa no rendimento de carcaça e suas partes sendo equivalente ao tratamento com antibióticos. Não foi observada diferença significativa entre os tratamentos, inclusive nos controles que não receberam qualquer fator aditivo. Da mesma forma os demais parâmetros de desempenho foram equivalentes para os quatro tratamentos, com exceção do ganho de peso, que foi significativamente menor no tratamento probiótico. Conclui-se que esses aditivos são uma alternativa importante na substituição dos antibióticos como melhoradores de crescimento, os quais já foram banidos em muitos países.

“…The results found at the starter phase were contradictory when compared with those obtained by Hooge et al (2004), Flemming & Freitas (2005) and Meurer et al (2010), who found, in a generalized manner, improvement in feed conversion in both broilers from the AGP group and those fed diet containing BS.…”

Evaluation of the use of probiotic (Bacillus subtilis C-3102) as additive to improve performance in broiler chicken diets

-The objective of this experiment was to evaluate the use of probiotic based upon Bacillus subtilis C-3102 (BS) in broiler diets containing or not conventional additive growth-promoter (AGP). A total of 1,824 one-day-old chicks of the Cobb-500 strain were used and distributed into 48 plots (1.50 × 2.00 m). A completely randomized design with four treatments and 12 repetitions was adopted. The treatments evaluated were: 1-Negative Control -AGP-free diet (NC); 2 -Positive Control, with AGP halquinol 30 mg/kg diet (PC); 3 -NC + BS (3x10 5 cfu/g diet); and 4 -PC + BS (3x10 5 cfu/g diet). The diets were on corn, soybean meal and meat and bone meal basis, formulated according to the nutrient allowances of the Strain Cobb Guide, following a feed program with three diets (starter, grower and finisher). At 21 and 42 days of age, feed intake, weight gain and feed conversion were evaluated, and carcass yield characteristics were determined at 42 days of age. Throughout the trial period (starter and total phases), better feed conversion was found for broilers fed diet with both additives (AGP and BS) combined. At the end of the experiment (1 to 42 days), the highest weight gain also occurred in broilers fed diets with a combination of the two additives. In present study, the use of BS or AGP alone in diets did not affect the performance of broilers. The carcass yield was not influenced by the use of the additives and beneficial effects of supplementation of BS and AGP combined in the diet on broiler performance were observed.
