“…3A) likely represents the ruminal cooling effect of feeding, reported by other authors as well (e.g. Cunningham et al, 1964), and the subsequent increase in the temperature difference probably reflects the heat of fermentation in the rumen, also discussed elsewhere (Reynolds, 1999).…”

“…However, there are limitations in using rumen temperature as a measure of T b . In cattle, average rumen temperature is usually 0·8–1·6°C higher than abdominal or rectal temperature (Cunningham, Martz, & Merilan 1964; Beatty et al. 2008).…”

Summary1. Measuring physiological and behavioural parameters in free-ranging animals -and therefore under fully natural conditions -is of general biological concern but difficult to perform. 2. We have developed a minimally invasive telemetry system for ruminants that is capable of measuring heart rate (HR), body temperature (T b ) and locomotor activity (LA). A ruminal transmitter unit was per os placed into the reticulum and therefore located in close proximity to the heart. The unit detected HR by the use of an acceleration sensor and also measured T b . HR and T b signals were transmitted via short-distance UHF link to a repeater system located in a collar unit. The collar unit decoded and processed signals received from the ruminal unit, measured LA with two different activity sensors and transmitted pulse interval-modulated VHF signals over distances of up to 10 km. 3. HR data measured with the new device contained noise caused by reticulum contractions and animal movements that triggered the acceleration sensor in the ruminal unit. We have developed a software filter to remove this noise. Hence, the system was only capable of measuring HR in animals that showed little or no activity and in the absence of rumen contractions. Reliability of this 'stationary HR' measurement was confirmed with a second independent measurement of HR detected by an electrocardiogram in a domestic sheep (Ovis aries). 4. In addition, we developed an algorithm to correctly classify an animal as 'active' or 'at rest' during each 3-min interval from the output of the activity sensors. Comparison with direct behavioural observations on free-ranging Alpine ibex (Capra ibex) showed that 87% of intervals were classified correctly. 5. First results from applications of this new technique in free-ranging Alpine ibex underlined its suitability for reliable and long-term monitoring of physiological and behavioural parameters in ruminants under harsh field conditions. With the battery settings and measurement cycles used in this study, we achieved a system lifetime of approximately 2 years.

“…Muskoxen may also reduce the effort of regulating ruminal conditions during winter because the endogenous heat increment after consumption of a standard meal declines between summer and winter; that is, muskoxen spend less energy on processing a meal in winter than in summer (Lawler and White 2003). Furthermore, ingestion of cold fluids and reductions of ruminal temperatures (Cunningham et al 1964) may also reduce microbial populations and activities in muskoxen during winter. Fermentative processes such as ureolysis and fiber adhesion are impaired at low temperature (Olubobokun et al 1988;Roger et al 1990; Barboza et al 1997).…”

We studied castrated adult muskoxen fed a standard diet of grass hay and supplement throughout the year to determine seasonal changes in digesta passage, fill, and fermentation without the confounding effects of reproductive demands or changes in food quality. Although food intake increased by 74% between spring and autumn, mean retention times of fluid and particulate digesta markers were maintained between seasons in both the rumen (9-13 h) and the intestines (27-37 h). The rumen contained 84.5% of digesta and accounted for 79% of dry matter digestion in the whole digestive tract. Ruminal fluid space and whole-gut digesta fill increased by 31%-34%, while ruminal rates of in situ degradation increased by more than 100% between spring and autumn for cellulose and hemicellulose. Hyperphagia in autumn was accompanied by increased bacterial counts in ruminal fluid (30%), declines in ruminal pH, and increases in the concentration of fermentation acids (16%) when compared with spring hypophagia. Consumption of fresh hay and supplement increased the concentrations of acids most markedly during winter and spring when bacterial counts were low. Low food intakes in winter and spring may limit the microbial population, whereas hyperphagia in autumn may foster a much more active microflora that requires consistent supplies of substrate. Plasticity of fill and fermentation in muskoxen minimizes winter costs and maximizes nutrients and energy gained from coarse forages in small home ranges throughout the year.
