We studied 50 consecutive patients to test the hypothesis that successful treatment of obstructive sleep apnea with nasal continuous positive airway pressure (nasal CPAP) will decrease automobile accidents in apnea. Thirty-six (72%) reported using CPAP regularly during 2 yr. Fourteen they had not used The this study a higher crash rate than all drivers state Colorado (0.07 versus 0.01 per driver year, p < 0.02). Patients who were treated lower while being before 0 0.03). Untreated continued...
The objective of this study was to investigate the effect including plantain (Plantago lanceolata L.; PL) in a perennial ryegrass (Lolium perenne PRG) and white clover (Trifolium repens WC) pasture mixture grazed by dairy cows on DMI, milk production composition, N excretion throughout grazing season. Twenty-six (6 primiparous 20 multiparous) Holstein-Friesian were blocked parity assigned 1 2 dietary treatments, balanced for economic breeding index, calving date, BW BCS at calving,...
Abstract Background Despite its importance to animal production potential, genetic gain for forage nutritive value has been limited in perennial ryegrass ( Lolium perenne L.) breeding. The objective of this study was phenotype a training population and develop prediction models assess the potential predicting organic matter digestibility (OMD) neutral detergent fiber (NDF) with genotyping‐by‐sequencing data. Methods Near infra‐red reflectance spectroscopy calibrations OMD NDF were developed...
The objective of this experiment was to investigate the effect concentrate supplement level and type on milk fat production grazing dairy cows in early mid-lactation during a high-risk period for reduced synthesis. Eighty Holstein Friesian averaging (mean ± SD) 55 14 DIM were blocked based their pre-experimental parity randomly assigned 1 5 dietary treatments: pasture-only (P) control supplemented with 0.27 kg DM/cow per day mineral vitamin pack (P0); P 2 an industry-standard (P2); 4 (P4);...
Abstract Increasing herbage dry‐matter ( DM ) production and utilization on‐farm improves efficiency sustainability. The objective of this study was to investigate the effect perennial ryegrass, Lolium perenne L., ploidy white clover, Trifolium repens inclusion on in an intensive animal grazing system, with high nitrogen (N) inputs (250 kg N ha −1 a stocking rate (2.75 livestock units ). 2 × factorial design, consisting diploid tetraploid cultivars sown as grass‐only grass‐white clover give...
Grazed grass is considered the cheapest feed available for dairy cows in temperate regions, and to maximise profits, farmers must utilise this high-quality where possible. Recent research has reported that including white clover (Trifolium repens L.) swards can have a positive effect on milk production. The aim of present study was quantify tetraploid diploid perennial ryegrass (Lolium perenne L.; PRG) sown with without production grazing cows. Four treatments were used study;...
The objective of this study was to investigate the effect cow genotype and parity on dry matter intake (DMI) production efficiencies in pasture-based systems. Three dairy genotypes were evaluated over 3 yr; 40 Holstein-Friesian (HF), Jersey × HF (JEX), Norwegian Red JEX (3WAY) each year, with grazed equal numbers 1 4 grazing treatments a 2 factorial arrangement [diploid or tetraploid perennial ryegrass (Lolium perenne L.) without white clover (Trifolium repens L.)]. A total 208 individual...
For ruminant production systems, the requirement to meet specific nutrient targets in animal’s diet must be balanced with aim of achieving high utilisation forage overall feed budget. A focus research and extension an Irish industry context has been these objectives using grazed pasture as predominant source. This prompted investigation improve understanding components defining nutritive value, well management factors affecting its intake by animals. Similarly, quantifying animal performance...
The objective of this study was to examine fluctuations in white clover (Trifolium repens L.) content perennial ryegrass (Lolium perenne swards within a high nitrogen (250 kg N/ha) input grazing dairy system. data came from larger, overall system experiment which all management and growing condition variables were categorised each year for the 40 paddocks that contained ryegrass-white swards, over four years. Within study, eight cultivars examined, sown individually with two 50:50 mix...
Context High nitrogen (N)-fertiliser application levels and high stocking rates have been shown to optimise herbage dry-matter (DM) production in grass-only systems. Conversely, swards including white clover (Trifolium repens L.) are commonly suited systems at low N-fertiliser (&lt;150 kg N/ha) (fewer than two livestock units (LU) per hectare). Despite this, the use of N fertiliser on grass–clover has generally increased during past few decades, particularly more intensively managed...
