Effects of a mixture of and fibrolytic enzymes on silage fermentation, aerobic stability, and performance of growing beef cattle.

This study evaluated the effects of novel silage inoculants containing lactic acid bacteria and fibrolytic enzymes on ensiling, aerobic stability , and the performance of growing beef cattle. Whole-plant corn forage was either uninoculated or inoculated with a mixture of LAB containing (cfu g fresh forage) 1.5 × 10 (CNCM I-4785), 1.

Effects of feeding a pine-based biochar to beef cattle on subsequent manure nutrients, organic matter composition and greenhouse gas emissions.

Biochar in ruminant diets is being assessed as a method for simultaneously improving animal production and reducing enteric CH emissions, but little is known about subsequent biochar-manure interactions post-excretion. We examined chemical properties, greenhouse gas (GHG) emissions and organic matter (OM) composition during farm scale stockpiling (SP) or composting (CP) of manure from cattle that either received a pine-based biochar in their diet (BM) or did not (RM). Manure piles were monitored hourly for temperature and weekly for top surface CO, NO and CH fluxes over 90 d in a semiarid location near Lethbridge, AB, Canada.

Molecular speciation and aromaticity of biochar-manure: Insights from elemental, stable isotope and solid-state DPMAS C NMR analyses.

The use of biochar (BC) in feedlot cattle diets has recently been explored as an approach to simultaneously improving animal production and reducing enteric methane (CH) emissions. This study examines the impact of BC on manure properties and whether BC affects manure composition and carbon (C) and nitrogen (N) outputs from feedlot steers offered a barley-based diet with BC at 0.0, 0.

Effect of a pine enhanced biochar on growth performance, carcass quality, and feeding behavior of feedlot steers.

The objective of this study was to evaluate the effect of enhanced biochar (EB) on growth performance, carcass quality, and feeding behavior of feedlot steers fed high-forage and high-grain diets. A total of 160 crossbred steers (initial 286 ± 26 kg body weight [BW]) were blocked by BW and randomly assigned to 16 pens (10 steers per pen), 8 of which were equipped with the GrowSafe system for monitoring feeding behavior. Treatments were EB included in the diet at 0% (control), 0.
