Agroecological tropical farming systems through crop–livestock integration

An analysis of the operations and performance of 17 farms in three different tropical zones (Guadeloupe, Brazil, Cuba) demonstrates that systems are more agroecological, efficient and resilient when a diverse range of activities are practiced and nutrient cycles are closed with higher-intensity crop–livestock integration flows.

Precision livestock farming at the service of animal welfare

Precision tools are of increasing importance on livestock farms, usually to improve production efficiency. Several of them were discussed during the INRA-IRSTEA symposium held during the Clermont-Ferrand Livestock Summit in 2018. Numerous systems utilise the activity of animals to detect those which are sick or in heat. But information on activity is still under-used to evaluate animal behaviour and wellbeing, even though behaviour is generally a good reflection of how an animal is feeling in terms of its good or poor condition.

Macaws that blush: facial expressions demonstrated for the first time in birds

In order to carry out studies of facial behavioural indicators, INRA scientists teamed up with the Beauval Zoo to look at blue-and-yellow macaws (Ara ararauna), who have the distinctive characteristic of having a portion of their cheeks devoid of feathers. During their experiment, the scientists were able to describe for the first time facial expressions in the birds within a context of positive valence: the macaws blushed and ruffled their crown feathers.
