“…Pens were randomly assigned to receive one of three treatments: (1) no Celmanax supplementation during the experiment (n = 7 pens), (2) supplementation with Celmanax (14 g/steer daily) from days 14 to 69 (n = 7 pens) or (3) supplementation with Celmanax (14 g/ steer daily) from days 31 to 69 (n = 7 pens). Celmanax inclusion rate was based on Ponce et al (2012), and according to manufacturer's recommendation (Church & Dwight Co., Inc.). Celmanax consists of the liquid medium used to grow strains of Saccharomyces cerevisiae; hence composed of dead cell walls, the medium, and an undetermined number of live yeast cells.…”

“…Supplementing cattle with yeast-derived products, such as yeast cultures and extracts, has been shown to enhance immune function during feedlot receiving (Cole et al, 1992;Brown and Nagaraja, 2009). Ponce et al (2012) supplemented heifers during a 35-day feedlot receiving period with a commercial source of yeast culture + enzymatically hydrolyzed yeast products (Celmanax). These authors reported greater ADG, dry matter (DM) intake and reduced morbidity in supplemented v. non-supplemented heifers, and associated these outcomes to innate immunomodulatory properties of Celmanax components such as β-glucans and mannanoligosaccharide (Nocek et al, 2011).…”

However, Ponce et al (2012) did not evaluate immune and physiological responses to elucidate the biological benefits of Celmanax supplementation. Moreover, Ponce et al (2012) began supplementation 1 day after feedlot arrival, which is after the critical period of stress caused nutrient deprivation during road transport (Marques et al, 2012).…”

Hence, we hypothesized that beginning Celmanax supplementation to beef cattle before transport, such as within a 30-day post-weaning preconditioning period (Pritchard and Mendez, 1990), would further increase cattle health and performance during feedlot receiving.…”

This experiment evaluated the impacts of supplementing a yeast-derived product (Celmanax; Church & Dwight Co., Inc., Princeton, NJ, USA) on productive and health responses of beef steers, and was divided into a preconditioning (days 4 to 30) and feedlot receiving phase (days 31 to 69). In all, 84 Angus × Hereford steers were weaned on day 0 (BW=245±2 kg; age=186±2 days), and maintained in a single group from days 0 to 3. On day 4, steers were allocated according to weaning BW and age to a 21-pen drylot (4 steers/pen). Pens were randomly assigned to (n=7 pens/treatment): (1) no Celmanax supplementation during the study, (2) Celmanax supplementation (14 g/steer daily; as-fed) from days 14 to 69 or (3) Celmanax supplementation (14 g/steer daily; as-fed) from days 31 to 69. Steers had free-choice access to grass-alfalfa hay, and were also offered a corn-based concentrate beginning on day 14. Celmanax was mixed daily with the concentrate. On day 30, steers were road-transported for 1500 km (24 h). On day 31, steers returned to their original pens for the 38-day feedlot receiving. Shrunk BW was recorded on days 4, 31 and 70. Feed intake was evaluated daily (days 14 to 69). Steers were observed daily (days 4 to 69) for bovine respiratory disease (BRD) signs. Blood samples were collected on days 14, 30, 31, 33, 35, 40, 45, 54 and 69, and analyzed for plasma cortisol, haptoglobin, IGF-I, and serum fatty acids. Preconditioning results were analyzed by comparing pens that received (CELM) or not (CONPC) Celmanax during the preconditioning phase. Feedlot receiving results were analyzed by comparing pens that received Celmanax from days 14 to 69 (CELPREC), days 31 to 69 (CELRECV) or no Celmanax supplementation (CON). During preconditioning, BRD incidence was less (P=0.03) in CELM v. CONPC. During feedlot receiving, average daily gain (ADG) (P=0.07) and feed efficiency (P=0.08) tended to be greater in CELPREC and CELRECV v. CON, whereas dry matter intake was similar (P⩾0.29) among treatments. No other treatment effects were detected (P⩾0.20). Collectively, Celmanax supplementation reduced BRD incidence during the 30-day preconditioning. Moreover, supplementing Celmanax tended to improve ADG and feed efficiency during the 38-day feedlot receiving, independently of whether supplementation began during preconditioning or after feedlot entry. These results suggest that Celmanax supplementation benefits preconditioning health and feedlot receiving performance in beef cattle.

“…Una de esas alternativas, para minimizar el impacto ruminal de las dietas que contienen granos, es el uso de levaduras vivas ya que tienen muchas ventajas (Evans et al, 2012), mismas que además de contribuir a mejorar la eficiencia alimenticia (White et al, 2008;Holtshausen y Beauchemin, 2010;Ondarza et al, 2010a), producción y contenido de proteina en leche (Shaver y Garrett, 1997;Ondarza et al, 2010b), ganancia diaria de peso (Ponce et al, 2012), incremento de las poblaciones de microorganismos totales del rumen (Fokkink et al, 2009) y en muchos casos el incremento en la digestibilidad de los forrajes (Bacha, 2002), aunque en otros no presentan efecto (Hinman et al, 1998;O'Connor et al, 2002). Los betaglucanos presentes en la pared externa de las levaduras estimula el sistema de defensa natural del organismo; además de estimular de forma selectiva el crecimiento de las poblaciones de bacterias consumidoras de lactato (Megaspharera elsdenii y Selenomonas ruminantium) lo que reduce la presencia de ácido láctico, evitando así las caídas pronunciadas de pH ruminal, lo que disminuye la incidencia de acidosis y por lo tanto los problemas digestivos, las cojeras y los altos conteos de células somáticas asociadas a esta causa (Clayton et al, 1999;Bacha, 2002).…”

Levadura viva (Saccharomyces cerevisiae) en la degradabilidad in vitro de una dieta para bovinos basada en forraje más concentrado Resumen S e evaluaron cuatro niveles de cultivo de levadura viva (Saccharomyces cerevisiae) en la digestibilidad in vitro de una dieta para bovinos basada en forraje más concentrado. Se utilizó líquido ruminal de dos toros fistulados, como inoculo bacteriano. Se emplearon dos incubadores Ankom® para digestibilidad in vitro, donde se depositaron bolsas F57 (Ankom Technology) que contenían las muestras de tratamientos experimentales. Los tratamientos fueron; T1: dieta testigo a base de forraje más concentrado, T2: T1 más 1 g de CL (Cultivo de levadura) kg -1 de alimento, T3: T1+2 g de CL kg -1 de alimento y T4: T1+3 g de CL kg -1 de alimento. La incubación se efectuó en siete tiempos; y la degradación se detuvo mediante refrigeración a 4 ºC. El experimento duró 90 días. Se evidenció a las 3, 12 y 72 h de incubación ruminal, la degradabilidad in vitro (DRIV) de la materia seca (DIMS), no presentó cambios por efecto de la suplementación del CL. No obstante, aunque de una manera no lineal, este CL provocó diferencias para los periodos de incubación de 0, 6, 24 y 48 horas. La DRIV de la materia orgánica (DIMO) tampoco presentó un comportamiento lineal por efecto de la adición creciente del CL a la dieta base, existiendo diferencias sólo en los tiempos de incubación de 3, 24 y 48 horas, pero no en el mayor tiempo de incubación (72 h). Los CL no provocan cambios claros en la degradabilidad de las dietas estudiadas.Palabras clave: cultivo de levadura, incubación in vitro, king grass, líquido ruminal Abstract F our levels of live yeast (Saccharomyces cerevisiae) culture in the in vitro digestibility of a more concentrated forage based cattle diet were evaluated. Ruminal fluid of two fistulated bulls was used, as a bacterial inoculum. Two Ankom® incubators were used for in vitro digestibility, where F57 bags (Ankom Technology) containing the samples of experimental treatments were deposited. The treatments were; T1: control diet with more concentrated forage, T2: T1 plus 1 g of CL (Yeast Culture) kg -1 of feed, T3: T1 plus 2 g of CL kg -1 of feed and T4: T1 plus 3 g of CL kg -1 of food. The experiment was developed in the Laboratory of Nutrition Rumiology and Metabolism with a duration of 90 days. In vitro dry matter degradability (DIMS) showed no changes at 3, 12 and 72 h of ruminal incubation because of CL supplementation. However, although in a non-linear manner, this CL caused differences for the incubation periods of 0, 6, 24 and 48 hours. The DRIV of organic matter (DIMO) did not present a linear behavior because of the increasing addition of CL to the base diet. There were differences only in incubation times of 3, 24 and 48 hours, but not in the longest incubation time (72 h). CLs do not cause clear changes in the degradability of the diets studied.
