The objective was to determine the long-term effect of 3-nitrooxypropanol (3-NOP) on CH
The objective of this study was to investigate whether the CH4 mitigation potential 3-nitrooxypropanol (3-NOP) in dairy cattle affected by basal diet (BD) composition. experiment involved 64 Holstein-Friesian cows (146 ± 45 d milk at start trial; mean SD) 2 overlapping crossover trials, each consisting measurement periods. Cows were blocked according parity, milk, and yield, randomly allocated 1 3 diets: a grass silage-based (GS) 30% concentrates 70% silage (DM basis), silage- corn...
Diurnal patterns of ruminal fermentation metabolites and microbial communities are not commonly assessed when investigating variation in CH4 production. The aims this study were to monitor diurnal of: (i) gaseous dissolved metabolite concentrations the bovine rumen, (ii) H2 emitted, (iii) rumen microbiota. Furthermore, effect dietary inclusion linseed oil on these was assessed. Four multiparous cannulated cows used a cross-over design with two 17-d periods treatments: control diet...
The aim of this study was to determine the methane (CH4) mitigation potential 3-nitrooxypropanol and persistency its effect when fed dairy cows in early lactation. Sixteen Holstein-Friesian (all multiparous; 11 their second parity 5 third parity) were blocked pairs, based on actual calving date, parity, previous lactation milk yield, randomly allocated 1 2 dietary treatments: a diet including 51 mg 3-nitrooxypropanol/kg dry matter (3-NOP) placebo at same concentration (CON). Cows 35% grass...
Grass silage is typically fed to dairy cows in temperate regions. However, vivo information on methane (CH(4)) emission from grass of varying quality limited. We evaluated the effect two rates nitrogen (N) fertilisation grassland (low (LF), 65 kg N/ha; and high (HF), 150 N/ha) three stages maturity at cutting: early (EM; 28 days regrowth), mid (MM; 41 regrowth) late (LM; 62 CH(4) production by lactating cows. In a randomised block design, 54 Holstein-Friesian (168±11 milk; mean±standard...
DNA based methods have been widely used to study the complexity of rumen microbiota, and it is well known that method extraction a critical step in enabling accurate assessment this complexity. Rumen fluid (RF) fibrous content (FC) fractions differ substantially terms their physical nature associated microorganisms. The aim was therefore assess effect four (RBB, PBB, FDSS, PQIAmini) differing cell lysis and/or recovery on observed microbial diversity RF FC using samples from cannulated dairy...
Next to rumen acidosis, other forms of acidosis may also affect lactational performance cows. Therefore, the effects hindgut induced via abomasal infusion ground corn, and metabolic NH4Cl, were studied in cows early lactation. Observations made on intake digestibility nutrients, lactation performance, energy N partitioning, blood acid-base status, fermentation characteristics. In a 6 × Latin square design, rumen-fistulated, second-lactation Holstein-Friesian dairy (48 ± 17 d milk) subjected...
Rumen microbial communities are known to drive methane (CH 4 ) production, but their dynamics in variable “real-world” farming environments less understood. This research aims identify specific taxa linked CH emission commercial dairy farms by employing 16S rRNA gene sequencing, thereby providing a more ecologically relevant understanding of production real-world settings.Rumen fluid samples were collected from 212 cows across seventeen Dutch farms. Methane was measured these using the...
This study aimed to investigate the effect of administering a standardized blend cinnamaldehyde, eugenol, and capsicum oleoresin (CEC) lactating dairy cattle for 84 d (i.e., 12 weeks) on enteric CH4 emission, feed intake, milk yield composition, body weight. The experiment involved 56 Holstein-Friesian cows (145 ± 31.1 in at start trial; mean SD) completely randomized block design. Cows were blocked pairs according parity, lactation stage, current yield, randomly allocated 1 2 dietary...
Estimating daily enteric hydrogen (H2) and methane (CH4) emitted from dairy cattle using spot sampling techniques requires accurate schemes. These schemes determine the number of samplings their intervals. This simulation study assessed accuracy H2 CH4 emissions various for gas collection. Gas emission data were available a crossover experiment with 28 cows fed twice at 80% to 95% ad libitum intake, an that used repeated randomized block design 16 libitum. Gases sampled every 12 15 min 3...
