Contrary to elevated C[O.sub.2], [O.sub.3], or UV-B decreases CMIC, metabolisable
C, and soil Nt content leading to higher C/N of soil organic matter.
However, unreplicated feed tests conducted by farmers have shown that this halophytic pasture species can produce forage that is suitable as a maintenance diet for ruminants throughout the summer period, with ash concentrations ranging from 10 to 12%, metabolisable
energy values up to 9.5 MJME/kg DM, and crude protein up to 17%, when the sward has been well managed.
Canola oil was included in the diets to increase the content of metabolisable
energy (ME) according to NRC (1998) standards.
A typical analysis shows a dry matter of 67-70%, crude protein of 9.5-10.5% and a metabolisable
energy content of 14-14.5MJ/kg.
energy intake and daily energy expenditure in relation to the size of herbivorous waterfowl: limits set by available foraging time and digestive performance.
Influence of growth type and season on the prediction of the metabolisable
energy content of herbage by near-infrared reflectance spectroscopy.
A limit to metabolisable
energy intake in mammals and birds.
Efficiency of metabolisable
energy utilization requirement for maintenance ([k.sub.m]), the ratio of net energy requirement for maintenance (NEm)/MEm, was used to determine metabolisable
energy requirement in beef cattle feeding system worldwide.
Up to 8 weeks of age, the birds were fed starter diet having crude protein (CP) 18 % and metabolisable
energy (ME) 2750 Kcal/kg of feed.
A second sample was dried at 60oC for 48 h prior to grinding through first a 5 mm and then a 1 mm screen, and a 150 g sub-sample of this material was then dried at 80EC for 24h to determine neutral detergent fibre (NDF), acid detergent fibre (ADF), crude protein (CP), DM digestibility (DMD), digestible organic matter (OM) on a DM basis (DOMD), water soluble carbohydrates (WSC) and metabolisable
energy (ME) by near Infrared infrared reflectance spectroscopy (NIRS) using a Bruker multi-purpose analyser (MPA, Bruker Optik GmbH, Ettlingen, Germany) and OPUS software (version 5.1) with calibrations developed by the New South Wales' Department of Primary Industries' Feed Quality Service (FQS).
energy content was determined by calculation from fat, carbohydrate and protein contents using conversion factors, 4kcal/g for protein, 9 kcal/g for fat and 4 kcal/g for carbohydrates.
