Einsatz von behandelten Saatwickenkörnern (Vicia sativa L.) in der Legehennenfütterung

Die Saatwicke ist eine proteinreiche Körnerleguminose, enthält aber antinutritive Faktoren. Basierend auf der Hypothese dass eine Behandlung ihren Futterwert verbessern kann, haben wir rohe, gekeimte und silierte Wicken sowie eine Kontrollration in einem Fütterungsversuch mit Legehennen verglichen

An updated method for the jugular catheterization of grower pigs for repeated blood sampling following an oral glucose tolerance test

Jugular catheterization is a common procedure used under experimental conditions. However, there is considerable variation in the reported techniques, particularly for grower pigs (>40 kg and 10 mL) are required. This paper provides a complete methodology including the use of current equipment and anaesthetic regimen for grower pigs. This surgical jugular catheterization method was carried out in 30 large white grower pigs. Firstly, the pigs were habituated to human handling for at least two weeks prior to surgery. Animals were sedated and anesthetized. Following intubation, an incision was made in the jugular fossa, and the jugular vein was located. A catheter was then inserted and fixated. The wound was stapled and the catheter line secured to the back of the neck. The pigs recovered fully from the surgery and the catheters remained patent for the duration of the blood sampling period (min 72 h). Twenty millilitres of blood were collected every 15 min, taking approximately 2 min per pig. No haemolysis was detected in any samples. Jugular catheterization of pigs using this procedure proved successful both in terms of animal recovery and quality of samples. Catheters remained patent and pigs remained calm during sampling

Case study of a newly-developed genotype for dual-purpose rearing of male chicks

Session 62, Theatre 3International audienceThe culling of male layer chicks has been subject to widespread disapproval and led to its ban in Germany and France.One approach to divert from this practice is the use of dual-purpose genotypes (DPG) with a balanced performancein egg and meat production. Practitioners and stakeholders selected males of a DGP with a focus on laying (C) foron-farm evaluation under organic conditions in France and Germany. In Germany, the medium-growing JA757 (D)while in France the naked neck strain S757N (F) were reared as control groups. Data collection included mortality,feed consumption, live weight, welfare indicators, behaviour observations and carcass characteristics. In Germany,C cockerels were slaughtered at 16 while D at 13 weeks (wks) of age. In France there were two slaughter dates for Cand F: 13 and 15 wks of age. In Germany, the carcass weight of C was 1.8 kg and that of D 2.4 kg. Carcass weights(incl. necks) at 13 and 15 wks of age were 2.9 and 3.3 kg for F while C weighed 2.0 and 2.5 kg in France. The FCRof DPG C until wk 13 was 3.7 for both countries, and 2.6 for F and 2.7 for D. In Germany, D showed dirtier breastsand more footpad lesions than C; on behavioural aspects, D spent more time resting than C while C spent more timeforaging. DPGs could be an alternative to end the practice of chick culling, and thus fulfil the societal demand fora shift towards welfare-oriented production. A longer fattening period with higher FCR of DPG cockerels may beeconomically feasible if their meat is sold at higher price than that of usual genotypes. A perspective is to decipherwhether they could valorise side products of the food industry to decrease feeding cost. Furthermore, the productivityof the females should be considered for a complete economical analysis of DPG.

Welfare barriers and levers for improvement in organic and low-input outdoor pig and poultry production systems

International audienceThe PPILOW project aims to co-construct innovations to improve Poultry and Pig Welfare in Low-input outdoor and Organic farming systems through a multi-actor approach. Its first step was to sum up animal welfare challenges observed in these systems and levers of improvement, from a review of literature data and research projects. Data were completed with information from key informants of the supply chains of poultry meat, eggs and pork in Italy, France, the United Kingdom and Finland. The interviews indicated that the main issues in poultry were: feeding, biosecurity, lack of range use and range management, feather pecking, weather, regulation, flock size or density, predation, bone fractures, lack of robustness, parasitism, pododermatitis, arthrosis, nervousness, water quality, catching and time spent by farmers. The main issues in pig were: feeding, tail biting, mortality, weather, predation, lack of robustness, lack of range use, castration, animal aggressiveness and competition, water quality, range management, human welfare, biosecurity issues, flock size or density, parasitism, insolation burns, joint abnormalities, parturition in freedom and pollution. This information has implemented a participatory approach for proposing welfare-improvement levers. Some issues and potential solutions were included in PPILOW experiments (phytotherapy against parasitism, involvement of animal personality in range use, rearing of entire pig males, genetic selection for reduced piglet mortality, improved farrowing huts for sows and piglets reared on range, avoiding feather pecking in laying hens with intact beaks, avoiding the killing of day-old male chicks etc.), and solution costs evaluated. The results will provide a combination of practical solutions for welfare improvement in Europe.

The PPILOW project: Innovations improving welfare in low input and organic pig and poultry farms

International audienceThe PPILOW project aims to co-construct innovations to improve Poultry and Pig Welfare in Low-input outdoor and Organic farming systems through a multi-actor approach. PPILOW implements a participatory approach for proposing and studying welfare-improvement levers. It will provide a combination of practical solutions that can be applied at a pan-European level with specific adjustments depending on citizen’s expectations and the target market. The multi-actor approach consists in involving end-users including farmers, breeding companies, feed producers, consumer associations, retailers, advisers, processors, and scientists in National Practitioner Groups (NPG) in six participating countries. PPILOW partners facilitate the groups by connecting NPG at European level, transferring scientific information, interacting with partners engaged in animal experiments, and co-creating innovations rising from NPG-specific demands. They co-build with PPILOW partners welfare self-assessment tools (development of the PIGLOW app for pigs and refinement of the EBENE® app for poultry), and innovative breeding, feeding, and rearing strategies and techniques to improve the welfare of animals. They co-design protocols, test innovations on farm, and disseminate the results. In turn, they receive insights on methods and scientific results, and inputs from other NPG reinforcing the value of the expected outcomes. Approaches focus on avoiding physical damage and the elimination of layer male chicks, on reducing boar taint of intact male pigs, promoting positive behaviours, animal health, and robustness through field studies with pigs and poultry. Multicriteria analyses of the most effective levers of welfare improvement will be performed to evaluate their economic, social, and environmental impacts based on the ‘One Welfare’ concept; economic and business models will also be developed. To ensure the rapid uptake of the project results by end-users, the close involvement of PPILOW’s NPG throughout the EU will ensure disseminationactivities and the facilitation of change.
