“…Currently, materials from cut 6 growth stage are used for comparison of cultivar performance as a standard protocol (UK National List Statutory Ryegrass trials; Dr T. Gilliland, personal communication). Mellon & Sharma (2002) reported that 'poorly digestible materials were associated with a high WL value in the first peak (PK1)', and this conclusion was based on results from an initial study. 1).…”

“…The TG runs were at a heating rate of 20°C min 21 through a temperature range of 30-600°C at an airflow rate of 20 mL min 21 (Mellon & Sharma, 2002), and the change in sample weight was monitored continuously at 4-s interval.

“…The nutritional value of maize measured as cell wall digestibility has been evaluated by both thermogravimetry (TG) and differential scanning calorimetry (DSC) (Marvin et al, 1996). Mellon & Sharma (2002) reported a preliminary study on the use of TG for assessing digestibility of perennial ryegrass. Thermal analysis can identify changes in proportions of non-structural (carbohydrate), structural (such as ligninhemicellulose complex and cellulose) and inorganic components of grass (Mellon & Sharma, 2002).…”

Thermal analysis can identify changes in proportions of non-structural (carbohydrate), structural (such as ligninhemicellulose complex and cellulose) and inorganic components of grass (Mellon & Sharma, 2002). In the past decade, the application of TG for quality evaluation of cell wall fractions in a range of plant materials including peat (Bergner & Albano, 1993), flax fibre and wheat straw have been reported by Sharma & Kernaghan (1988) and Sharma et al (2000).…”

Thermogravimetry (TG) can be used for assessing the compositional differences in grasses that relate to dry matter digestibility (DMD) determined by pepsincellulase assay. This investigation developed regression models for predicting DMD of herbage grass during one growing season using TG results. The calibration samples were obtained from a field trial of eight cultivars and two breeding lines. The harvested materials from five cuts were analysed by TG to identify differences in the combustion patterns within the range of 30-600°C. The discrete results including weight loss, peak height, area, temperature, widths and residue of three decomposition peaks were regressed against the measured DMD values of the calibration samples. Similarly, continuous weight loss results of the same samples were also utilised to generate DMD models. The r 2 for validation of the discrete and the best continuous models were 0.90 and 0.95, respectively, and the two calibrations were validated using independent samples from 24 plots from a trial carried out in 2004. The standard error for prediction of the 24 samples by the discrete model (4.14%) was higher than that by the continuous model (2.98%). This study has shown that DMD of grass could be predicted from the TG results. The benefit of thermal analysis is the ability to detect and show changes in composition of cell wall fractions of grasses during different cuts in a year.

“…With a thermogravimetric analysis apparatus, pyrolysis characteristic experiments of king grass (Pennisetum purpureum Â P. american) were carried out at different heating rates [27]. Mellon and Sharma [28] determined the relationships between DTG weight-loss parameters of perennial ryegrass and dry matter digestibility.…”
