Abstract:
Eimeria bovis, Eimeria zuernii, Eimeria ellipsoidalis, Eimeria auburnensis, Eimeria canadensis and Eimeria alabamensis were identified on different dairy farms in Uruguay. The most prevalent species were E. bovis and E. zuernii, which were mainly found in the feces of calves with diarrhea. The dynamics of oocyst excretion were evaluated via the weekly determination of oocysts per gram (OPG) values in fecal samples from 97 calves over seven months. Three groups of calves were formed according to their age in days: Group 1 (1?20 days old), Group 2 (21?40 days old) and Group 3 (41?65 days old). In Group 1, the median OPG was zero, and the maximum OPG was 1,680. In Group 2, the median OPG was between zero and 8,240, and the maximum OPG was 428,800. In Group 3, the median OPG was between zero and 220, and the maximum OPG was 16,000. For the evaluation of the relationship between OPG and age group, a proportional odds model was built. Two samples from 60 bovines evaluated in Group 2 and in Group 3 were selected. OPG was categorized as negative, moderate (lower than or equal to 4,000) or high (greater than 4,000). Calves of Group 2 (21?40 days old) were significantly (p < 0.001) more affected by eimeriosis than calves of Group 3 (41?65 days old). Considering that diarrhea in calves is a multifactorial disease, eimeriosis should be considered when evaluating the control measures for diarrhea syndrome, particularly in calves of 21?40 days of age. |

Investments in high quality phenotyping are needed to fully exploit the potential of genomic data, and consequently, to contribute for more efficient plant selections, shorter breeding cycles, and rapid advances in breeding. Based on a global network of wheat partners, several precision fieldbased wheat phenotyping platforms are being developed with the support of the CGIAR Research Program on Wheat and co-investing national agricultural research institutes. The objective is to generate higher precision multi-location phenotypic data on prioritized traits, under defined good practices, short- and longer-term training and sharing of the generated knowledge, as well as fostering global germplasm exchange among participating NARS and scientists. The selected locations represent key environments, as for example, hotspots for specific diseases and future climate analogue sites. Within this network, phenotyping activities are being conducted for wheat blast (Magnaporthe oryzae) in Bolivia, Septoria tritici blotch (STB) in durum wheat in Tunisia, and for multiple diseases (leaf rust, Fusarium head blight, and STB) in bread wheats in Uruguay. Subject to further funding, additional platforms to be developed include the ones for evaluation of heat and drought tolerance (Morocco - already funded - India, Pakistan, Bangladesh, Nepal, Turkey), yield potential (China, India, Pakistan, Egypt, Zimbabwe), and wheat diseases (China, Turkey, Bangladesh-Nepal). The generated information will contribute to a faster development of broad genetic based resistant, high yielding wheat varieties, complementing evaluations currently performed for diseases (Kenya, Ethiopia, Turkey, Mexico) and heat/drought/yield potential (Mexico).
