“…The current study demonstrated no benefit in apparent digestibility of DM, ADF, or NDF from the inclusion of yeast culture in the diet of mature horses. These results agree with the work reported by Webb et al (1985), Hall et al (1989), and Markey et al (2006) who reported no significant differences of apparent digestibility of nutrients by mature horses, 3 yr olds, or yearlings, respectively. The lack of effect on apparent digestibility could be attributed to insufficient intake or digestion and absorption of the yeast culture proximal to the hindgut (Webb et al, 1985;Hall et al, 1989).…”

The objective of this study was to test the hypothesis that feed additives such as chelated minerals, organic Se, yeast culture, direct-fed microbials, and Yucca schidigera extract would improve nutrient digestibility when included in an equine diet. Horses (Quarter Horse geldings 4.5 to 16 yr of age; mean BW 522 kg ± 46 kg) were acclimated to 100% pelleted diets formulated with (ADD) and without (CTRL) commercially available sources of the aforementioned additives followed by a 14-d collection period of feces and urine. Chelated sources of Cu, Zn, Mn and Co were utilized versus sulfated forms, at a 100% replacement rate. No significant differences among apparent the digestibility of DM, ADF, or NDF (P= 0.665, P = 0.866, P = 0.747, respectively) were detected between dietary treatments. Likewise, no differences in apparent digestibility of Cu (P = 0.724), Zn (P = 0.256), Mn (P = 0.888), Co (P = 0.71), or Se (P = 0.588) were observed. No differences were observed in serum Cu, Mn, or Co concentrations between ADD and CTRL at acclimation or collection time points (P > 0.05). While no difference in serum Zn concentrations were observed between ADD and CTRL groups at acclimation (P > 0.05), they were statistically higher at the collection time period for horses consuming CTRL (P < 0.0001). Whole blood Se concentration was greater in the CTRL group versus the ADD group both at acclimation (P = 0.041) and collection (P = 0.005) time periods. In reference to time, serum Cu concentrations increased (P = 0.012) for animals consuming CTRL, but not ADD (P > 0.05). Serum Zn concentrations of horses consuming both ADD (P = 0.021) and CTRL (P < 0.0001) increased over time from acclimation to collection time points. No time differences (P > 0.05) were observed in serum Mn concentrations. Serum Co concentrations increased over time in horses consuming both ADD (P = 0.001) and CTRL (P = 0.021). From acclimation to collection, whole blood Se concentration increased for horses consuming CTRL (P = 0.01) but not for ADD (P > 0.05). The results of this study indicate no effect on nutrient digestibility due to the inclusion of chelated minerals, organic Se, yeast culture, direct-fed microbials, and Yucca schidigera extract for horses at maintenance.

“…Por outro lado, Ribeiro (1998) relatou que a melhoria na digestibilidade proteica com a inclusão de levedura pode ser decorrente do aumento na atividade microbiana no intestino grosso, favorecendo a digestibilidade de compostos nitrogenados. Hall et al (1990) estimaram a digestibilidade de MS, PB, EE, FDN e FDA em potros alimentados com uma dieta à base de concentrado e volumoso com inclusão diária de levedura nos níveis de 0, 10, 20 e 40 g/animal e também relataram não ter ocorrido efeito da suplementação com levedura.…”

RESUMO -Com o objetivo de avaliar o efeito do uso de probiótico (Saccharomyces cerevisiae) em dietas para cavalos, utilizaram-se quatro equinos machos com média de 400 kg de peso corporal, em delineamento em quadrado latino 4 × 4. As dietas foram compostas de concentrado e feno de capim-tifton 85 (de baixa qualidade) ou feno de alfafa (de alta qualidade), com ou sem a adição de levedura. Cada período experimental teve duração de 36 dias, com coleta total de fezes, para determinação dos coeficientes de digestibilidade aparente dos nutrientes, e coleta de fezes, para determinação do pH e da microbiologia fecal. A utilização de probiótico não alterou os coeficientes de digestibilidade aparente dos nutrientes das dietas, com exceção do extrato etéreo. A qualidade nutricional do feno influenciou os coeficientes de digestibilidade da matéria seca (MS), da proteína bruta (PB) e do extrato etéreo (EE) apenas no caso das dietas com feno de capim-tifton sem probiótico e com feno de alfafa com probiótico. A utilização de cultura de levedura aumentou a população de Lactobacillus nas fezes dos animais que receberam a dieta com feno de capim-tifton com probiótico. Não houve uso de probiótico na população de Lactobacillus nas dietas com feno de alfafa (de boa qualidade). A população de Streptococcus nas fezes aumentou com suplementação de levedura, tanto na dieta com feno de capim-tifton como naquela com feno de alfafa. A dieta com capimtifton 85 sem probiótico promoveu redução nos valores de pH fecal 14 e 17 horas após a alimentação. Considerando ainda os valores de pH fecal nesses períodos após a alimentação, as dietas suplementadas com probiótico apresentaram valores superiores àqueles obtidos sem adição de levedura.Palavras-chave: cavalos, digestibilidade aparente, fezes, microbiologia, probiótico, volumoso Use of yeast in equine fed diets with hay with different nutritional qualitiesABSTRACT -In order to evaluate the effect of using probiotic (Saccharomyces cerevisiae) in diets for horses, it was used four male equines, with average body weight of 400 kg, in a 4 × 4 Latin square design. Diets were composed of concentrated and 85 Tifton grass hay (low quality) or alfafa hay (high quality), with or without addition of yeast. Each experimental period lasted 36 days, with total fecal collection for determination of apparent digestibility coefficients of the nutrients and fecal collection for determining pH and fecal microbiology. Use of probiotic did not affect apparent digestibility coefficients of the diets, except for ether extract. Hay nutritional quality affected coefficients of dry matter digestibility, crude protein and ether extract (EE) only for diets with Tifton grass hay without probiotic and with alfafa hay with probiotic. The utilization of yeast culture increased the Lactobacillus population in feces of animals fed diet with Tifton grass hay with probiotic. Probiotic was not used in population of Lactobacillus in diets of alfafa hay (good quality). Streptococcus population in the diet increased as yeast was supp...

“…Hill y Gutsell (1998) observaron un aumento de la digestibilidad de la FDN y la absorción intestinal del fósforo (P) en equinos que recibieron raciones con probióticos. Sin embargo, Hall et al (1990) no observaron efecto de la suplementación con levaduras a niveles crecientes sobre la digestibilidad de la MS, PB, FDN y de la energía. Por otro lado, Kim et al (1991) verificaron una mayor digestibilidad de la MS, PB, FDN, FDA, hemicelulosas y P en animales que consumieron una dieta con levaduras vivas y concluyeron que el mayor aprovechamiento de la PB y del P fue debido al estímulo de la actividad microbiana que aumentó tanto el reciclaje del nitrógeno endógeno como la producción de fitasa en el intestino grueso.…”
