The study objective was to evaluate the combined effects of supplementing monensin (MON) and methane (CH4) inhibitor 3-nitrooxypropanol (NOP) on enteric CH4 emissions, growth rate, feed conversion efficiency backgrounding finishing beef cattle. Two hundred forty crossbred steers were used in a 238-d feeding fed diet for first 105 d (backgrounding phase), transition diets 28 d, followed by (finishing phase). Treatments as follows: 1) control (no additive); 2) MON (monensin supplemented at 33...
Objective . To summarize the recent studies on effect of conjugated linoleic acid (CLA) hepatic steatosis and adipose lipid metabolism highlighting potential regulatory mechanisms. Methods Sixty-four published experiments were summarized in which trans -10, cis -12 CLA was fed either alone or combination with other isomers to mice, rats, hamsters, humans compared. Summary Conclusions Dietary induces a severe mice more muted response species. Regardless species, when present, concurrent...
The study addressed the importance of yeast (Saccharomyces cerevisiae) viability for reducing incidence subacute ruminal acidosis (SARA) and improving total tract nutrient digestibility in beef heifers. Six ruminally cannulated heifers (680 ± 50 kg BW) were used a replicated 3 × Latin square design fed diet consisting 40% barley silage, 10% chopped grass hay, 50% grain-based concentrate (DM basis). Treatments 1) no (Control), 2) active dried (ADY; 4 g providing 10(10) cfu/g; AB Vista,...
The study objective was to evaluate the effects of sustained reduction enteric methane (CH4) emissions with dietary supplementation inhibitor 3-nitrooxypropanol (NOP) on growth rate and feed conversion efficiency growing finishing beef cattle. Eighty-four crossbred steers were used in a 238-d feeding fed backgrounding diet for first 105 d (backgrounding phase) transition diets 28 followed by (finishing 3 doses NOP (0, 100, 200 mg/kg DM). experiment completely randomized design using 21 pens...
The objective of the present study was to determine dose response methane (CH4) inhibitor 3-nitrooxypropanol (NOP) on enteric CH4 production and dry matter intake (DMI) for beef cattle fed a high-forage or high-grain diet. Fifteen crossbred yearling steers were used in two consecutive studies (high-forage backgrounding, finishing), each designed as an incomplete block with 28-day periods 7-day washout between treatments corresponding six doses NOP (0 (Control), 50, 75, 100, 150, 200 mg/kg...
Abstract The individual and combined effects of 3-nitrooxypropanol (3-NOP) canola oil (OIL) supplementation on enteric methane (CH4) hydrogen (H2) emissions, rumen fermentation biohydrogenation, total tract nutrient digestibility were investigated in beef cattle. Eight heifers (mean body weight ± SD, 732 43 kg) with ruminal fistulas used a replicated 4 × Latin square 2 (with without 3-NOP) OIL) arrangement treatments 28-d periods (13 d adaption 15 measurements). four were: control (no 3-NOP,...
Abstract Background The major greenhouse gas from ruminants is enteric methane (CH 4 ) which in 2010, was estimated at 2.1 Gt of CO 2 equivalent, accounting for 4.3% global anthropogenic emissions. There are extensive efforts being made around the world to develop CH mitigating inhibitors that specifically target rumen methanogens with ultimate goal reducing environmental footprint ruminant livestock production. This study examined individual and combined effects supplementing a high-forage...
Abstract We evaluated the effects of a Bacillus-based direct-fed microbial (DFM) on total in vitro gas production, dry matter (DM), neutral detergent fiber (NDF), and starch disappearance different feedstuffs mixed rations (TMR) three experiments. In experiment 1, six single fiber-based were evaluated: alfalfa hay, buffalo grass, beet pulp, eragrostis oat smutsvinger grass. Experimental treatments control (with no probiotic inoculation; CON) or incubation mixture containing Bacillus...
The objectives of this study were to evaluate the relationship between residual feed intake (RFI; g/d) and enteric methane (CH) production (g/kg DM) compare CH carbon dioxide (CO) emissions measured using respiration chambers (RC) GreenFeed emission monitoring (GEM) system (C-Lock Inc., Rapid City, SD). A total 98 crossbred replacement heifers group housed in 2 pens fed barley silage ad libitum their individual intakes recorded by 16 automated feeding bunks (GrowSafe, Airdrie, AB, Canada)...
We evaluated the effects of supplementing bacterial direct-fed microbial (DFM) on performance, apparent total-tract digestibility, rumen fermentation, and immune parameters lactating dairy cows. One hundred fourteen multiparous Holstein cows (41 ± 7 DIM) were used in a randomized complete block design with an experiment comprising 14 d covariate (pre-experimental sample data collection) 91 experimental period. Cows blocked based energy-corrected milk (ECM) yield during period following...
Twenty ruminally cannulated beef heifers were fed a high corn grain diet in randomized block design to determine the effect of three direct microbial (DFM) strains Propionibacterium on ruminal fermentation, nutrient digestibility and methane (CH4) emissions. The blocked five groups basis BW used 28-day periods. Dietary treatments included (1) Control (2) P169, (3) P5, (4) P54. Strains administered directly into rumen at 5×109 CFU with 10 g maltodextrin carrier gel capsule; received only. All...
This study examined the effects of chopping or + blender maceration red clover lucerne on pre-fermented juice (PFJ) and determined PFJs quality silage silage. The from (PFJ-RC) (PFJ-LC) had a higher lactic acid bacteria (LAB) count than that (p < 0.05) were used as additives. Compared with Control both silages, adding PFJ increased LAB, (LA), in vitro digestibility dry matter (IVDMD) 0.05), while pH, acetic (AA), ammonia nitrogen/total nitrogen (NH3-N/TN) decreased 0.05). For PFJ-RC...
The objective of this study was to test the efficacy different Propionibacterium strains in mitigating methane (CH4) emissions beef heifers fed a high-forage diet. Twenty ruminally cannulated were used randomized block design with 28-d periods. Treatments included 1) Control, 2) acidipropionici strain P169, 3) P5, and 4) jensenii P54. Strains (5 × 10(9) CFU) administered daily directly into rumen 10 g maltodextrin carrier gel capsule. Control received only. All basal diet (70:30 forage...
