“…Furtado et al (2010) also found no probiotic influence on dietary fiber usage in horses with daily 15 g yeast supplementation. However, Agazzi et al (2011) found an improvement in DM, OM, NDF and ADF usage in the diet when horses were supplemented with 50 g of yeast. Another factor to be considered was that animal diets from both groups were balanced and provided the necessary nutrients for horses undertaking moderate activity (NRC, 2007).…”

This research analyses the yeast supplementation effect on the digestibility of nutrients and metabolic performance in training horses. Twelve horses were assigned into 2 groups: Pr (20 g of probiotics daily per horse) and control. The diet consisted of roughage (haylage) and commercial rations and all horses were trained for 6 weeks. LIPE ® indicator was used during 7 days and feces collected for five days to determine nutrient digestibility. DM, CP, DE, P, NDF, ADF, HCEL and lignin were determined. All horses were subjected to incremental ergospirometry test before and at the end of training. Horses that received live yeast showed an increase (p<0.05) of 4.1% in the digestibility of HCEL. After training, both horse groups presented higher tolerance to fatigue, with an increase in AT and VO2max. The training improved animal performance, hemicellulose digestibility and DE was higher in Pr, but these increases did not improve the performance of these animals.Index terms: Nutritional additives, equine, exercise, probiotics. RESUMOO trabalho avaliou o efeito da suplementação com leveduras na dieta de equinos em treinamento, sobre a digestibilidade dos nutrientes e o desempenho metabólico dos animais. Doze equinos foram distribuídos em 2 grupos: Pr (equinos que receberam 20 g de probióticos diariamente) e Controle. A dieta foi composta de volumoso (haylage) e concentrado comercial e todos os equinos foram treinados durante 6 semanas. A digestibilidade dos nutrientes foi avaliada utilizando o indicador LIPE ® (7 dias) e a coleta de fezes foi realizada durante cinco dias. Foi analisado MS, PB, DE, P, FDN, FDA, HCEL e lignina. Antes e após o treinamento, todos os cavalos foram submetidos a um teste incremental ergoespirométrico. Os equinos que receberam leveduras vivas apresentaram um aumento (p <0,05) de 4,1% na digestibilidade da HCEL. Após o treinamento, ambos os grupos apresentaram maior tolerância à fadiga, com um aumento na AT e no VO2max. O treinamento melhorou o desempenho dos animais, e a digestibilidade da hemicelulose e DE foi maior no grupo Pr, mas esses aumentos não melhoraram o desempenho desses animais.Termos para indexação: Aditivos nutricionais, equino, exercício, probióticos.

“…In contrast, acid insoluble ash (AIA) is an indigestible, naturally-occurring marker made of inorganic material (silica) in feeds that can also be measured in feces (Agazzi et al, 2011), allowing for apparent digestibility determination using the following calculation (Schneider and Flatt, 1975):…”

“…While this indirect method also requires a fecal collection apparatus to avoid soil contamination of silica with the fecal sample (Agazzi et al, 2011), it only requires enough fecal sample to accommodate the 20 g dry-sample minimum for analysis.…”

“…There have been multiple studies comparing total collection and the AIA method (Sutton et al, 1977;Van Keulen and Young, 1977;Doyle et al, 1994;Agazzi et al, 2011). Sutton et al (1977) demonstrated no significant difference between apparent digestibility of energy and nitrogen based on method (total collection and AIA), using geldings (n = 4) fed a grain and hay mix (Exp.…”

“…De acordo com Julliand (2006), a digestibilidade da matéria seca (MS), fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), proteína bruta (PB), energia bruta (EB) e hemicelulose da dieta varia com a cepa do microrganismo, a quantidade suplementada e a composição da dieta. Kim et al (1991) Agazzi et al (2011) também registraram maior digestibilidade aparente da MS e FDA em equinos adultos consumindo dieta com alto teor de fibra e suplementados com levedura. Já Lattimer et al (2007) testando o efeito da suplementação com leveduras em equinos consumindo dietas com alta proporção de fibra ou alta proporção de concentrado observaram aumento (p<0,05) somente na produção de acetato, nas dietas com alta proporção de concentrado.…”

ResumoO trabalho avaliou o efeito da suplementação com leveduras sobre a digestibilidade e consumo dos nutrientes de equinos Mangalarga Marchador submetidas a treinamento. Quatorze éguas Mangalarga Marchador foram distribuídos em dois grupos: Probiótico (equinos suplementados com 20 g de Saccharomyces cerevisiae diariamente) e Controle. A dieta foi composta por volumoso e concentrado comercial, na proporção de 50:50. As éguas foram treinadas durante seis semanas, de segunda a sábado, sendo o exercício realizado diariamente alternando o trabalho em esteira ergométrica e caminhador automático. A digestibilidade dos nutrientes foi avaliada utilizando o indicador LIPE ® (6 dias) e a coleta de fezes foi realizada durante cinco dias. Foi analisado MS, FDN, FDA, PB, EB, hemicelulose e consumo de matéria seca. Não houve diferença (P>0,05) em nenhuma das variáveis analisadas. A suplementação com 20 g de Saccharomyces cerevisiae não interfere na digestibilidade e consumo dos nutrientes em éguas Mangalarga Marchador submetidas a seis semanas de treinamento aeróbico. Palavras-chave: Equino, fibra, hemicelulose, levedura, probiótico AbstractThe study evaluated the effect of yeast supplementation on the digestibility and intake of nutrients of Mangalarga Marchador horses in training. Fourteen Mangalarga Marchador mares were divided into two groups: Probiotic (horses supplemented with 20 g of Saccharomyces cerevisiae daily) and Control. The diet consisted of commercial concentrate and roughage in the ratio of 50:50. The mares were trained for six weeks, Monday to Saturday, and the exercise performed daily alternating work on a treadmill and automatic walker. Nutrient digestibility was assessed using the indicator LIPE ® (6 days) end fecal collection was performed for five days. Was analyzed DM, NDF, ADF, CP, GE, hemicelluloses and dry matter intake. There was not difference (P>0,05) in any of the variables analyzed. Supplementation with 20 g of Saccharomyces cerevisiae does not affect the digestibility and nutrient intake in mares Mangalarga Marchador submitted six weeks of aerobic training.
