The objective of this study was to evaluate the genotypic stability of agronomic traits in hybrids of Panicum maximum. Hybrids originating from the crosses between two sexual parents and cultivars Mombasa and Tanzania were evaluated in an incomplete-block design. Evaluated traits were total dry matter, leaf dry matter, stem dry matter, percentage of leaves, and leaf:stem ratio. These traits were evaluated in six harvests. Overall, higher repeatability was observed for the traits total dry matter and leaf dry matter, especially when harvests 4, 5, and 6, occurring in spring and summer, were evaluated. The leaf dry matter was the trait that provided the greatest repeatability and determination. The repeatability of stem dry matter, percentage of leaves, and leaf:stem ratio had a low magnitude, even when the coefficient was estimated based on the harvests of better stabilization for the other variables. The hybrids achieved genotypic stabilization in the harvests made in the second rainy season. Harvests made in the rainy season provide greater repeatability and determination, and the inclusion of the dry-season harvest is detrimental to the process of selection of low-repeatability traits such as percentage of leaves. |

The aim of the present study was to determine the prevalence of Babesia bovis and Babesia bigemina in dairy cattle from São Luis Island in the state of Maranhão, Brazil. A total of 281 blood samples were collected. In total, 275 (97.9%) animals were B. bovis-reactive and B. bigemina-reactive in the Enzyme-Linked Immunosorbent Assay (ELISA). The microscopy examination detected 22 (7.8%) animals that were positive for Babesia sp. and the Polymerase Chain Reaction (PCR) analysis showed that 91 animals (32.38%) and 23 animals (8.18%) were positive for B. bovis and B. bigemina, respectively, while 17 animals (6.04%) were co-infected. There is a high level of transmission of these protozoa in Maranhão, and the animals were naturally exposed. Therefore, it is possible to characterize the island as enzootic stability for babesiosis, indicat-ing a risk of financial losses when susceptible animals are introduced from areas of enzootic instability or free regions of B. bovis and B. bigemina. |
