An empirical analysis of the cost of rearing dairy heifers from birth to first calving and the time taken to repay these costs [PDF]

, 2017
Rearing quality dairy heifers is essential to maintain herds by replacing culled cows. Information on the key factors influencing the cost of rearing under different management systems is, however, limited and many farmers are unaware of their true costs.

Microplastics from Wearable Bioelectronic Devices: Sources, Risks, and Sustainable Solutions

Advanced Functional Materials, EarlyView.
Bioelectronic devices (e.g., e‐skins) heavily rely on polymers that at the end of their life cycle will generate microplastics. For research, a holistic approach to viewing the full impact of such devices cannot be overlooked. The potential for devices as sources for microplastics is raised, with mitigation strategies surrounding polysaccharide and ...

The use of mid-infrared spectrometry to predict body energy status of Holstein cows [PDF]

, 2011
Energy balance, especially in early lactation, is known to be associated with subsequent health and fertility in dairy cows. However, its inclusion in routine management decisions or breeding programs is hindered by the lack of quick, easy, and ...

Cold Quad‐Modal Nanocomplex for Precise and Quantitative In Vivo Stem Cell Tracking

Advanced Functional Materials, EarlyView.
Multimodal albumin–bismuth sulfide–superparamagnetic iron oxide (ABS) nanocomplexes are developed for stem cell tracking across four different imaging modalities: MRI, MPI, MSOT, and CT. Combining its flexibility with high sensitivity, this quad‐modal imaging agent enables a robust quantification of ABS‐labeled stem cells in vivo.

Conséquences de l’augmentation de la prolificité sur l’élevage des agneaux et sur la production de viande

INRAE Productions Animales, 1991
L’accroissement de la taille de la portée entraîne une réduction du poids de chacun des agneaux produits. Cette diminution est de l’ordre de 20 % par agneau supplémentaire dans les races "classiques" et voisine de 15 % pour les races prolifiques.
