“…There continues to be increased pressure on livestock producers to reduce and/or remove antimicrobials from animal diets from both consumers and federal legislation (i.e., veterinary feed directive; Clark et al, 2012 ). Additionally, there is a demand from advocacy groups and consumers to produce cattle using more “natural” means, which includes halting the use of antimicrobials, growth implants, and other synthetic supplements in support of using nonsynthetic supplements ( Stackhouse et al, 2012 ; Ovinge et al, 2018 ). Therefore, there is an increasing number of cattle producers turning to natural or organic production systems ( Karreman, 2009 ).…”

“…Thus, the need exists to provide producers with viable alternatives to traditional management practices that allow producers to maintain cattle performance and health while helping them align with consumer demand and federal regulations ( McEwen and Fedorka-Cray, 2002 ). Currently, many different feed supplements are being produced and marketed that may be able to fill this need ( Kegley and Spears, 1995 ; Young et al, 2016 ; Ovinge et al, 2018 ).…”

“…There are many feed supplements that may have the ability to modulate the immune responsiveness of cattle and other livestock species. Various yeast and yeast-based products have been demonstrated to reduce the acute phase response while either not altering or improving performance ( Burdick Sanchez et al, 2013 ; Finck et al, 2014 ; Broadway et al, 2015 ; Ovinge et al, 2018 ). NatureSafe (Diamond V, Cedar Rapids, IA) is a Saccharomyces cerevisiae fermentation product (SCFP) that was developed to promote immunity in cattle.…”

This study was conducted to determine if feeding a Saccharomyces cerevisiae fermentation product (SCFP) to calves would alter the acute phase response to a lipopolysaccharide (LPS) challenge. Crossbred steer calves (n = 32; 274 ± 1.9 kg BW) were randomly allotted to 2 treatment diets for 21 d: 1) Control, fed RAMP (Cargill, Dalhart, TX), and 2) SCFP, fed the Control ration supplemented with NaturSafe at 12 g·hd-1·d-1 mixed into the TMR (NaturSafe®, Diamond V, Cedar Rapids, IA). On d 22, steers were fitted with indwelling jugular catheters and rectal temperature monitoring devices and placed in individual bleeding stalls. On d 23 steers were challenged i.v. with 0.25 µg/kg body weight LPS. Blood samples were collected at 0.5-h (serum) or 2-h (complete blood counts) intervals from -2 to 8 h and again at 24 h relative to the LPS challenge at 0 h. Sickness behavior scores (SBS) were recorded after collection of each blood sample. Rectal temperatures were greater in SCFP steers from 6 to 11 h, at 13 h, from 15 to 20 h, and from 22 to 24 h following the LPS challenge compared to Control steers (treatment × time: P = 0.01). Additionally, SCFP-supplemented steers had reduced (P < 0.01) SBS compared to Control steers. Platelet concentrations remained greater in SCFP-supplemented steers compared to Control steers throughout the study (P = 0.05), while there was a tendency (P = 0.09) for SCFP steers to have greater white blood cells and eosinophils concentrations than Control steers. There was a treatment × time interaction for serum cortisol and glucose (P < 0.01). Specifically, cortisol was greater at 0.5 and 2 h post-challenge but was reduced at 3 h for SCFP steers compared to Control steers. Glucose was greater in SCFP steers at -0.5, 2, and 7.5 h compared to Control steers. Serum amyloid A was reduced in SCFP steers at 0.5 h, yet greater at 1 and 7.5 h post-challenge compared to Control steers (treatment × time: P < 0.01). Fibrinogen concentrations were greater (P < 0.01) in SCFP compared to Control steers. There was a treatment × time interaction (P < 0.01) for tumor necrosis factor-α such that concentrations were reduced in SCFP steers from 1 to 2 h post-challenge compared to Control steers. Overall these data suggest that supplementing calves with SCFP may have primed the innate immune response prior to the challenge, particularly platelets, which resulted in an attenuated sickness behavior and TNF-α response to LPS.

“…Samples, DM, ash, CP, NDF, ADF, and hemicellulose (HEM) were also analyzed for each sample. The AIA concentration consumed and observed in fecal samples were used to calculate total tract apparent digestibility of individual nutrients, as described by Ovinge et al (2018).…”

“…The low digestibility of forages in ruminant diets may limit the supply of energy and nutrients. Several strategies may be used to improve fiber digestion in cattle diets, such as selection of forage hybrids (Bean et al, 2013), chemical treatments (Shreck et al, 2015), and use of direct-fed microbials (Ovinge et al, 2018). In addition, some exogenous fibrolytic enzymes have also been developed to improve fiber digestibility by ruminants (Krueger et al, 2008).…”

The effects of dietary pretreatment with fibrolytic enzyme-based cocktail were evaluated in 2 studies: (1) in vitro true digestibility; and (2) intake, digestibility, feeding behavior, and ruminal fermentation of beef steers fed growing diets. For the in vitro assessment, the ruminal inoculum was collected from 2 steers (BW = 543 ± 45 kg; 4-h after feeding; growing diets) and enzymes included or not (Trichoderma reesei fermentation extract; 0.75 µL/g of substrate DM). Within in vitro batches (n = 4), 12 substrates were incubated and in vitro true nutrient digestibility was evaluated. For study 2, 5 ruminally cannulated beef steers (BW = 520 ± 30 kg) were used in a 5 × 4 unbalanced Latin square using a 2 × 2 factorial arrangement of treatments: (a) diet quality (high = HQ; and low = LQ) and (b) enzyme inclusion (0 or 0.75 mL/kg of diet DM). Steers were fed ad libitum during four 21-d periods consisting of 14-d of adaptation and 7-d of collections. An enzyme × substrate was observed (P < 0.01), in which DM, OM, and NDF disappearance of sorghum grain increased with enzymes addition. Addition of enzymes increased (P < 0.01) ADF digestibility for all substrates. No diet quality × enzyme (P ≥ 0.18) was observed for intake variables in study 2. Enzyme-fed steers increased (P ≤ 0.05) intake of DM, digestible DM, NDF, and ADF compared with steers not fed fibrolytic enzymes. Addition of enzyme did not affect (P ≥ 0.28) apparent total tract digestibility of beef steers. Steers fed HQ diets consumed more (P ≤ 0.04) DM, digestible DM and OM, and less (P ≤ 0.03) total and digestible fiber than steers fed LQ diets. Ruminal pH average decreased (P = 0.01) for steers fed HQ or enzyme-fed diets compared with other treatments. A tendency (P = 0.06) toward improved total VFA was observed on enzyme-fed steers with HQ diets, but not for LQ diets. The molar proportion of ruminal propionate increased (P = 0.01) when steers were fed enzyme. Steers fed HQ diets had greater (P < 0.01) propionate and valerate molar proportions, lower (P < 0.01) acetate and acetate:propionate ratio than steers fed LQ diets. In vitro methane and total gas production were not affected (P ≥ 0.50) by dietary treatments. Fibrolytic enzymes positively affected digestion of multiple roughage sources commonly fed to cattle and might have additional benefit when used on unprocessed sorghum grain. Fibrolytic enzymes in beef cattle growing diets stimulated intake and generated positive impacts on ruminal fermentation.
