Productivity and persistence of sown pastures remain the main demands of Uruguayans producers, immersed in a context of sustainable intensification of production systems, with adaptation to climate change. In INIA Uruguay we have developed a wide range of approaches to address these issues. The exploration of the productive potential of native species and the incorporation of vegetative structures that favor competition and persistence as rhizomes are examples of the works that have been carried out in such diverse species as Paspalum notatum, Bromus auleticus, Lotus corniculatus, and Tall Fescue. With the addition of some biotechnological tools, we have also been planned long-term research and interspecific hybridization, seeking to incorporate new and higher productivity vegetative structures into agricultural interest species. An additional venue is to investigate and to develop those microorganisms responsible for biological nitrogen fixation in legumes, and for alkaloids production for plant protection as fungal endophytes in grasses. In the case of the rhizobia, a novel strategy was developed to seek and to characterize new strains better adapted to our
environmental conditions. The same strategy is now being used for developing new alfalfa strains. Fungal endophytes (from the Epichloë genus) present in a Bromus auleticus germplasm collection are being descripted and characterized for the first time. This
presentation resumes different strategies of genetic improvement of forage plants using contrasting cases. First, the case of native species Paspalum notatum and Bromus auleticus where the breeding scheme transited collection, molecular and agronomic characterization, and selection of genotypes adapted. Secondly, interspecific hybridization between species with the aim of combining vegetative structure with reproductive strategies, and finally investigating and developing different microorganism related to the productivity and persistence of forage species.

Abstract: Neospora caninum is a major reproductive disease in cattle worldwide. In the Argentinian Humid Pampa, the seroprevalence, incidence of abortions, and economic losses due to neosporosis are considerably higher in dairy than in beef cattle. Despite this, we recently demonstrated that N. caninum subpopulations are indistinctly distributed in both dairy and beef production systems. The association between genotypic characteristics defned by microsatellite analysis and the virulence of the different strains?particularly with regard to the severity and extension of histological lesions?is largely unknown. Herein, we used a morphometric approach to analyze encephalic lesions in 62 bovine fetuses spontaneously infected by N. caninum. Morphometric parameters (average size of focal lesions, number of foci/cm2 and the percentage of the section afected by lesions) were compared according to the N. caninum subpopulations found in our previous microsatellite genotyping analysis, animal biotype (beef versus dairy), and fetal age (second stage of gestation versus third stage). The average size of the lesions difered signifcantly among fetuses with diferent gestational ages; however, no signifcant diferences among animal biotypes or genotypic patterns were found. Further research into the genetic, molecular, and husbandry factors that could account for this greater impact in Argentinian dairy herds is needed. |
