Abstract:A Participatory rural appraisal (PRA) was conducted in dairy farms of the North West Region of Cameroon. The aim of the PRA was to have a better understanding of the prevailing dairy systems, identify problems, and set priorities for research and development that can contribute to improved systems of production. A multidisciplinary team of researchers and extension agents was constituted. It was made up of scientists of the following fields: cattle management, forage science, agro economy, veterinary, dairy technology, nutrition and extension. The research team visited farmers' groups and
divided itself into subgroups for farm and village walks during which direct observations were also noted. The extension agent of the locality, key informant, gave additional information overlooked by farmers. Interviews were also carried out with other stakeholders of the dairy sector. The research team met the day following the visit to agree on a common report. Results show that five small scale dairy production systems
are found in the region: transhumance, improved extensive, semi intensive, zero grazing
and peri-urban. Agriculture is well integrated to dairying. Main constraints include in
order of importance: poor marketing opportunities and long distances to market, limited
grazing land and poor supplementation of cattle, limited health control, inadequate
knowledge in processing, conservation and storage of milk, poor reproductive
management and prolonged calving interval, lack of water in the dry season, poor
housing, poor organization of group, limited number of dairy cows and poor record
keeping. In market oriented farms, reproduction and feeding were the most important
constraints. Main factors influencing dairy production are: milk collection, fresh milk
price, consumer demand, genotype and management. These results suggest that much
can be done to improve production by extending improved packages to dairy farmers.

Abstract:
Diversity of rhizobia nodulating Lotus corniculatus grown in geographical regions with different rainfall regimes in northern and southern Uruguay, was estimated using 168 root nodule isolates. ERIC-PCR analysis revealed no correlation between observed fingerprints and the geographical origin of isolates. Despite the commercial strain U510 has been used for decades to inoculate L. corniculatus, none of the isolates corresponded to this strain. Phylogenetic analyses using 16S rRNA and atpD genes, and ITS sequences clustered all the isolates within genus Mesorhizobium. A great majority of the isolates likely belong to the species M. huakuii, as does the commercial strain U510. The remaining isolates were closely related to either M. septentrionale or M. caraganae. Although no M. loti-like bacteria were identified, all isolates carried symbiotic genes closely related to M. loti and other narrow host range Lotus rhizobia. A significant portion of the Uruguayan isolates were as efficient as the reference strain U510 in symbiosis with L. corniculatus. A few of the isolates were also capable of nitrogen fixation in symbiosis with L. uliginosus, albeit with lower efficiency than reference strains. Our results indicate that rhizobia nodulating L. corniculatus in Uruguay are genetically and phenotypically diverse, and that the commercial strain U510 is probably not adapted to survive the Uruguayan edaphoclimatic conditions. |
