“…Because the in vitro technique used in the present study allows VFA to be produced but not absorbed as it happens in vivo (Carpenter et al 2017), our results indicate that more fermentationand consequently greater VFA productionoccurred when creep feed was added to the pure bermudagrass. Moreover, they show that the rumen microorganisms were able to ferment even more of these compounds when the treatment BGLUC was used.…”

Two experiments were conducted to evaluate the inclusion of feed enzymes into beef cattle creep feeds. In the first one, the following treatments were tested in vitro: (1) 100% bermudagrass (GRASS); (2) a mixture of 75% bermudagrass and 25% creep feed (CREEP); (3) CREEP enhanced with endo-1,4-βxylanase (XYLAN); (4) CREEP enhanced with endo-1,3(4)-β-glucanase (BGLUC). Degradation of fibre was greatest (P ≤ 0.03) for BGLUC, whereas in vitro dry matter digestibility was greatest (P = 0.01) for XYLAN. In the second experiment, cow-calf pairs from 2 farms were split into 3 groups: (1) Group with no supplementation of calves (NO FEED); (2) Group where calves were supplemented in a creep feeding system (PLAIN FEED); and (3) Same feed regimen as PLAIN FEED, but with the addition of endo-1,4-β-xylanase due to the positive results observed in experiment 1 (ENZYME FEED). There was a numerical increase in calf average daily gain in the 2 groups that were supplemented, however, only ENZYME FEED was significantly different (P ≤ 0.03) than NO FEED. At one farm, supplement gain:feed was improved (P = 0.01) in ENZYME FEED, compared to PLAIN FEED. Collectively, these results indicate that xylanase can be used to enhance beef cattle creep feeds.

“…An 8-unit, dual-flow, continuous culture fermenter system with a modified pH control and measuring system were used in two consecutive 10-d experimental periods, similar to that described by Hannah et al (1986) and fermenter operation was similar to Ruiz-Moreno et al (2015) , Carpenter, et al (2017) , and Fessenden et al (2017) . Treatments were randomly assigned and duplicated within experimental period to create a randomized complete block design with four observations per treatment.…”

“…Period served as block with all treatments equally represented within block. Forages were analyzed as a fixed effect and period (block) was a random effect ( Ruiz-Moreno et al, 2015 ; Binversie et al, 2016 ; Carpenter et al, 2017 ). All treatment results were reported with least squares means, with significance declared at P < 0.05.…”

The objective of this study was to compare warm-season annual grasses to cool-season perennial (CSP) grasses for ruminal nutrient digestibility and N metabolism in a dual-flow continuous culture fermentation system. Dietary treatments were 1) fresh alfalfa, 2) CSP grasses and legumes, 3) brown-midrib sorghum-sudangrass (BMRSS), and 4) teff grass from an organic dairy production system. Eight dual-flow continuous culture fermenters were used during two consecutive 10-d periods consisting of 7 d for stabilization followed by 3 d of sampling. Fermenter samples were collected on days 8, 9, and 10 for analysis of pH, NH3-N, and VFA. Apparent DM, OM, NDF, and ADF digestibility were on average lesser (P < 0.05) in CSP grasses and legumes and warm-season annual grasses compared with alfalfa. True DM and OM digestibility were lesser (P < 0.05) for CSP grasses and legumes and warm-season annual grasses compared with fresh alfalfa. Total VFA were not affected (P > 0.05) by forage. The NH3-N concentrations were highest (P < 0.05) with alfalfa compared with the other CSP grasses and legumes and warm-season annual grasses. CP digestibility was not affected (P > 0.05) by forage treatment. Flow of NH3-N was greatest (P < 0.05) for alfalfa, reflecting the greatest NH3-N concentration. Flow of total N was greatest (P < 0.05) for alfalfa, intermediate for teff, and lowest for CSP grasses and legumes and BMRSS. Flows of bacterial N, efficiency of bacterial N, non-NH3-N, and dietary N were not affected (P > 0.05) by forage source. Overall, fermentation of warm-season grasses was similar to the cool-season grasses and legumes which indicate dairy producers may use warm-season grasses without concerns about negative impact on rumen health.
