Der volle Inhalt der QuelleIn the early 2020s, suckler cattle producers in the Charolais region are facing a number of difficulties. Despite their real contribution to conservig biodiversity, storing carbon and maintaining the countryside, Charolais breeders are going through a serious crisis. These production units generate very low levels of added value, making farm income extremely dependent on public support. Added to this are socio-environmental factors, with farms that are highly vulnerable to the effects of climate change, a clearly arduous workload, particularly at calving time, and a rise in critical discourse about meat consumption that weighs heavily on the meaning of a farmer's job.However, there is nothing cyclical about these difficulties, which are the result of a major increase in herd size to the detriment of value added, against a backdrop of industrialisation of the sectors and liberalisation of agricultural and market policies.Using the cases of Saône-et-Loire and Nièvre, this doctoral thesis sets out to characterise and explain the crisis experienced by Charolais breeders, using a comparative agriculture approach supplemented by contributions from economics, sociology and agronomic sciences. Once the crisis has been characterised, attention will be paid to individual and collective attempts to change the situation, and to the conditions that need to be met if there is to be any hope of emerging from the crisis

Der volle Inhalt der QuellePermanent pastures represent potential reservoirs of forage and cover more than 66% of the area of mountain zones. Nonetheless, these zones have strong natural limitations that make it difficult to use herbage resources. Geographic characteristics of fields and farm organization must thus be considered in more detail in the management of forage areas to improve pasture-based livestock systems functioning. Simultaneous production of dairy and beef cattle herds (i.e. “mixed dairy-beef cattle systems”) falls within the scope of agroecological approaches and may appear as factor favoring the functioning of cattle systems with greater forage autonomy and better economic and environmental performances. We analyzed and modeled the functioning of these mixed dairy-beef cattle systems to explore compromises between livestock management and the production level of the herds, overall forage autonomy, use of the geographical diversity, level and variability of profits and sustainability of pasture use.To address this issue, we tested three hypotheses: (I)- Mixed dairy-beef cattle systems use grazed herbage better than specialized cattle systems (dairy or beef) in zones with constraints while maintaining good economic performance. (II)- Under conditions of optimal economic functioning, mixed dairy-beef cattle systems adapt better to price variations, generating more stable and higher profits, than specialized cattle systems. (III)- Mixed dairy-beef cattle systems use biomass well, with better environmental performances, while conserving ecosystem services of the vegetation.We used the bioeconomic optimization model Orfee (Optimization of Ruminant Farm for Economic and Environmental assessment), developed to assess livestock systems, based on data from two farms in a steady state (case studies BL18 and BL22 from the French livestock-network database DIAPASON). Orfee was adapted to consider geographic constraints and field heterogeneity based on the French typology of permanent prairies. We then used the model to predict the best equilibria, corresponding to optimal conditions of functioning of farms, represented by the two case studies in five scenarios (100D, 75D, 50D, 25D and 0D, where D represents the percentage of dairy cattle in the herd). Analysis with the simulations yielded robust biotechnical and economic indicators for assessing mixed dairy-beef cattle systems in mountain zones.Based on the results, mixed dairy-beef cattle systems, especially those with 50% dairy cattle, maximize the use of grazed herbage in zones with constraints on mechanization and access of dairy cows to pastures. These systems have a greater ability to adapt to economic variations, with better levels of animal production and more attractive and less variable economic performances than those of specialized cattle systems. These systems also have better compromises between environmental performances than specialized cattle systems

Der volle Inhalt der QuelleIn grassland based livestock systems, diversification of animal species is considered a tool allowing a reduced use of inputs. The present thesis aims at comparing practices of grass management, gastrointestinal parasitism management and work organisation of specialised saddle horse breeding systems and mixed saddle horse - beef cattle farming systems, which have been surveyed across two French pasture areas. The investigated mixed farms are on average larger than specialised equine farms. In the northern foothills of Massif Central, mixed farms have a higher farm stocking rate and buy less forage than specialised farms. There is a high land proportion grazed alternately by cattle (main production in this region) then horses. In Normandy, where horses have a higher genetic value, farm stocking rate is identical in both types of systems. Only the plots grazed alternately by horses then cattle (<10% of the total grazed area) are more heavily used than other grazing combinations. Grinding is less used there, as well as in plots grazed simultaneously by both species. Faecal egg counts carried out on young horses from the Massif Central show that those kept on mixed pasture with cattle excrete half as many strongyle eggs as those kept in specialised systems. This dilution effect of equine parasitism by cattle suggests that limiting the use of chemical drugs in mixed systems is possible, while treatments remain systematic in all surveyed farms. Saddle horse breeding requires a very large amount of routine work, due to the individual valorisation of young horses. Beef cattle breeding has little effect on the workload or its organisation. Work does not seem to be a factor preventing the implementation of mixed grazing. The link between analysis of practices, work organisation and economic performance of farms must be further investigated
