Diurnal Body Temperature and Rate of Passage of Loggers in Lions [PDF]

Animals, 2020
The documentation of diurnal patterns in body temperature in lions could be important because disruption of circadian patterns can be a useful measure of distress. This study quantified changes in body temperature of seven African lions (Panthera leo) at

Prediction models of reticulorumen particles and solutes passage rate in growing goats

Animal, 2022
The reticulorumen (RR) fractional passage rate (kp; /h) of particles and solutes plays an important role in fiber digestion, methane production, and microbial yield.

Rate of feed passage in Japanese quail

Animal, 2020
The rate of passage (ROP) in the gastrointestinal tract (GIT) influences the exposure time of food to the digestion and absorption processes. Consequently, ROP affects the efficiency of nutrient utilization and energy from the diet.

Ruminal fermentation and degradation, kinetic flow of digesta and milk fatty acid composition of cows fed sugarcane silage-based diets supplemented with whole cottonseed

Semina: Ciências Agrárias, 2020
The aim of this study was to evaluate the ruminal fermentation and degradation parameters, the kinetic flow of digesta in the gastrointestinal tract, and the milk fatty acid (FA) profile in Holstein x Gyr cows fed 59% sugarcane silage-based diets with 0%

A comparison of parameters of the passage of nylon capsules and digesta calculated from faecal excretion data obtained in lactating cows

Czech Journal of Animal Science, 2005
The aim of the study was to compare parameters of passage of nylon capsules and digesta represented by Cr-labelled maize silage through the digestive tract of dairy cows. The capsules were made of nylon cloth (42 µm pore size, 10 mm outside diameter) and

Universal tradeoff relation between speed, uncertainty, and dissipation in nonequilibrium stationary states

SciPost Physics, 2022
We derive universal thermodynamic inequalities that bound from below the moments of first-passage times of stochastic currents in nonequilibrium stationary states of Markov jump processes in the limit where the thresholds that define the first ...

Feed restriction strategy in the growing rabbit. 1. Impact on digestion, rate of passage and microbial activity

Animal, 2009
The effects of a quantitative feed restriction on the digestive physiology of the young rabbit remain largely unclear. Several digestive functions were thus analysed in the rabbit after weaning, using a monofactorial design that produces a linear ...
