Digital phenotyping of individual feed intake in Atlantic salmon (Salmo salar) with the X-ray method and image analysis

Frontiers in Animal Science, 2023
The primary barrier to research into feed efficiency of Atlantic salmon (Salmo salar) is the lack of a reliable method to assess individual feed intake in large cohorts of fish over a growth period.

Flow and passage rate studies at the ileal level in the rabbit [PDF]

Reproduction Nutrition Développement, 1989
Six female rabbits fitted with a simple glass cannula in terminal ileum and a further 6 non-cannulated rabbits were used to perform digesta flow and transit measurements. The animals received ad libitum a diet based mainly on lucerne meal. Flow and transit measurements were carried out using two particulate markers: ytterbium (Yb) fixed on lucerne meal

Replacement of wheat bran with spineless cactus in sugarcane-based diets for steers

Revista Brasileira de Zootecnia, 2016
The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum ...

Estimating entropy production rates with first-passage processes [PDF]

Journal of Physics A: Mathematical and Theoretical, 2022
AbstractWe consider the problem of estimating the mean entropy production rate in a nonequilibrium process from the measurements of first-passage quantities associated with a single current. For first-passage processes with large thresholds, references (Roldánet al2015Phys. Rev.
