Mass mortality associated with luminescence has been dbserved in sorne Thai and Ecuadorian penaeid shrimp hatcheries in recent years. Samples collected from hatcheries in these two different areas revealed luminescent sucrose-negative Vibrio strains in larVal rearing tanks where mortality occurred. Pathogenicity trials were carried out to identify the causative agents of mortality and to study the course of infection . . Results showed that strains isolated from Thai hatclleries were more virulent than Ecuadorian strains when tested on different larval stages of Penaeus monodon. The virulence of these strains was also estimated. Trials on other species ofpenaeid shrimp demonstrated the specifie action of Thai strains. Drug sensitivity patterns revealed a... |

The paper highlights particular benefits and challenges coming along with ruminant production on permanent grasslands and rangelands. A threefold synergy is i) the utilisation of a nutrient source which is independent of arable land, ii) the ecological benefits of maintained permanent pastures and iii) the production of food with a high nutritional and sensory quality. However, a sustainable use of these pastures requires appropriate management, facing very different challenges depending on the regional conditions. Systemic management schemes based on specific characteristics of the pastures are required for their maintenance and/or development. A further challenge are pasture-bound gastro-intestinal parasites control, which are, however at least partly... |

La séparation précoce mère-veau est une pratique courante dans la plupart des élevages laitiers, mais est sujette à de nombreuses interrogations tant chez les éleveurs (coûts engendrés, travail) que dans la société (bien-être animal). Des pratiques alternatives mises en place par certains éleveurs permettent aux veaux d'être allaités par leur mère ou une autre vache, appelée « nourrice ». Quoiqu’anciennes, ces pratiques demeurent peu connues et leur intégration aux conditions d’élevages modernes questionne. Des enquêtes ont ainsi été réalisées en 2018 pour connaître la motivation des éleveurs, la diversité et les conséquences de ces pratiques sur les résultats techniques. Cent deux élevages, identifiés par des réseaux divers (conseil en élevage, chambres... |

In dairy farms calves and cows are usually separated shortly after birth but this practice raises the question of animal welfare. This social concern may lead to bring back dairy calves to their mother. Even though suckling is quite seldom in dairy production, some farmers are using such a practice for many years. The present study aims to better know farmer’s motivations, practical implementation and farmer’s perception of the impact of suckling on performance and animal behaviour. In January 2018 a semi-quantitative survey was performed on 44 farms where calves suckle at least 24 hours their mother or a nurse cow. The farming systems differed on the size (20 to 140 cows), the type (19 conventional, 25 organic farms), the suckling (28 by the mothers, 16... |

Take home message: Various methods and practices are available to efficiently reared calves through suckling in dairy cows, using specific nurse cows or not. |
