A framework to estimate the environmentally attainable intake of dairy cows in constraining environments

open access: yesAnimal, 2023
Most intake models for dairy cows have been developed to make predictions under normal conditions, in which animals can meet their nutritional requirements. To estimate intake under constraining conditions, i.e.

Disentangling the dynamics of energy allocation to develop a proxy for robustness of fattening pigs

open access: yesGenetics Selection Evolution, 2023
Background There is a growing need to improve robustness of fattening pigs, but this trait is difficult to phenotype. Our first objective was to develop a proxy for robustness of fattening pigs by modelling the longitudinal energy allocation coefficient ...

Dairy goats adjust their meal patterns to the fibre content of the diet

open access: yesAnimal, 2021
Few studies have investigated how meal patterns of ruminants are affected by diet fibre content. Dairy goats (N = 32) in late lactation and early gestation were housed in eight groups of four goats, with all combinations of breed (Alpine and Saanen) and ...

Repeatability of traits for characterizing feed intake patterns in dairy goats: a basis for phenotyping in the precision farming context

open access: yesAnimal, 2020
In ruminants, feeding behaviour variables are parameters involved in feed efficiency that show variation among individuals. This study aimed to evaluate during the first two production cycles in ruminants the repeatability of feed intake pattern, which ...

Pour une analyse systémique de la technique : exemple de la production de terre cuite architecturale

open access: yesCahiers François Viète, 2019
Conceptual principles of systemic theory are applied through the example of architectural terracotta. They show that the implementation of the technique, such as its representation or improvement, depends largely on social, cultural or economic factors ...

Vers une approche systémique de l'évaluation

open access: yesThe Journal of Quality in Education, 2017
La problématique de l'évaluation est multidimensionnelle et de ce fait elle doit être approchée d'une maniêre systémique et globale. Le systême éducatif est un tout indissociable qui englobe des inputs, des processus et des outputs en interactions ...

Animal board invited review: Quantification of resilience in farm animals

open access: yesAnimal, 2023
Resilience, when defined as the capacity of an animal to respond to short-term environmental challenges and to return to the prechallenge status, is a dynamic and complex trait.

Maquette virtuelle cognitive. Entre espace de représentation et espace de conception [PDF]

open access: yesSHS Web of Conferences
L’expansion du numérique a provoqué la mutation du mode de représentation traditionnel de l’architecture vers la maquette virtuelle. D’un côté, l’aptitude du modèle architecturologique de Boudon à intégrer les nouvelles technologies est questionnée.

Modelling impacts of performance on the probability of reproducing, and thereby on productive lifespan, allow prediction of lifetime efficiency in dairy cows

open access: yesAnimal, 2016
Reproductive success is a key component of lifetime efficiency – which is the ratio of energy in milk (MJ) to energy intake (MJ) over the lifespan, of cows.

Quantifying growth perturbations over the fattening period in swine via mathematical modelling

open access: yesPeer Community Journal, 2022
Background: Resilience can be defined as the capacity of animals to cope with short-term perturbations in their environment and return rapidly to their pre-challenge status. In a perspective of precision livestock farming, it is key to create informative
