Abstract Elephant grass has high biomass production, with qualities suitable for conversion into bioenergy, but has long been used exclusively for animal feed and only in recent years has it become an energetic alternative. Therefore, it is necessary to select genotypes with potential for energy production. This study evaluated the effect of five harvest times (8, 12, 16, 20, and 24 weeks) on the yield and chemical composition related to biomass quality through combined polynomial regression analyses of the following elephant grass genotypes: Cubano Pinda, Mercker 86-México, Pusa Napier n°1, Mole de Volta Grande, P-241-Piracicaba, and King Grass. A completely randomized design with three replicates, in a split-plot arrangement, was adopted, including two factors (plots = genotypes, subplots = harvest times). The evaluated variables were whole-plant dry matter yield, in t ha-1 (DMY), percentage of neutral detergent fiber (%NDF), and percentage of acid detergent fiber (%ADF). The elephant-grass genotypes Cubano de Pinda, Mercker 86-México, and P-241-Piracicaba showed a linear first-degree effect as a function of the harvest intervals, indicating that they did not reach their maximum production potential. Genotypes Pusa Napier n°1, Mole de Volta Grande, and King Grass, in turn, had a linear second-degree effect. For the NDF variable, all genotypes showed a significant linear second-degree effect as a function of the harvest intervals, except P-241-Piracicaba, for which no regression was observed. For this genotype, there was a significant linear first-degree effect on the %ADF variable.

Resumo: O vírus da artrite encefalite caprina e vírus maedi visna são retrovírus, comumente designados de lentivírus de pequenos ruminantes, que causam sérias perdas econômicas. O objetivo deste trabalho foi avaliar e comparar proteínas de antígenos produzidos a partir de cepas do vírus da artrite-encefalite caprina (CAEV) e do vírus da maedi-visna (MVV), visando o imunodiagnóstico. Para tanto, os diferentes antígenos oriundos das cepas CAEV-Cork, CAEV-CE e MVV-K1514 foram submetidos à eletroforese em SDS-PAGE, posteriormente ao teste de Western Blot, a fim de se analisar as proteínas imunogênicas. O perfil proteico dos diferentes antígenos foram similares, apresentando bandas proteicas variando em peso molecular de 162,08 a 15,02KDa. Além disso, as seguintes proteínas imunogênicas foram observadas: gp45, p28, p19 e p15. Concluiu-se que os antígenos produzidos possuem características imunogênicas semelhantes, demonstrando a similaridade dessas cepas virais. Proteic and immunogenic analysis of antigen from Small Ruminants Lentivirus. Abstract: The caprine arthritis encephalitis virus and maedi visna virus are retrovirus, in general designated from Small Ruminants lentivirus, which causes serious economic prejudice. The objective of this study was evaluate and compare the different proteins expressed by antigens produced from strains of CAEV Cork, CAEV CE and MVV, aiming the immunodiagnosis. To this, different antigens samples arising from strains CAEV-Cork, CAEV-CE and MVV-K1514 were subjected to electrophoresis on SDS-PAGE, posteriorly to Western blot test, in order to analyze immunogenic proteins. The proteic profile and antigenic of the various antigens were similar, showing the protein bands ranging in molecular weight from 162.08 to 15.02 KDa. Furthermore, were present the following immunogenic proteins: gp45, p28, p19 and p15. It is concluded that the antigens produced were similar, demonstrating similarities of these viral strains.
