The results of the cross reactions of the 27 strains of Azospirillum spp. with 4 fluorescent antibodies (FA) show a neat differentiation between the two species. A. lipoferum represents a more homogenous group in respect to FA reactions and highly fluorescent preparations were obtained with strains from a large scope origin against Sp59 FA, the type strain. In contrast A. brasilense contains at least three sub groups in respect to FA reactions. The first includes all denitrifing strains (nir+) which react with FA from Sp7 the type strain. None of the nir- strains reacted strongly with Sp7 FA. One part of the A. brasilense nir- group which includes the strains isolated from well sterilized rice and wheat roots (Sp 107, 107 st, 106 and 109 st) reacts with FA of their reference strain Sp107 but not with that of Sp28 FA. The strains isolated from unsterilized roots and soils reacted with SP28 FA and not with that of Sp107 FA. In addition there were 3 strains (Sp A4, 34 and 67) which reacted with neither of the FAs. |

The present study aimed to evaluate the chemical composition, profle and fermentative losses, microbial population and the aerobic stability of mixed silages of cactus pear and gliricidia. The treatments corresponded to the addition levels of gliricidia (Gliricidia sepium (Jacq.) Steud), in the silages of cactus pear (Opuntia fcus indica Mill.), at ratios 0%, 25%, 50%, 75% and 100% gliricidia. The data were subjected to analysis of variance and regression to evaluate the efect of the addition levels of gliricidia. The average related to the opening days were compared by the Tukey?s test and the average hours of exposure to air were compared by the Student?s t-test. The addition of gliricidia in cactus pear silage provided a linear increasing efect for pH, crude protein (CP), neutral detergent fbre (NDF), acid detergent fbre (ADF), acid detergent lignin (ADL), neutral detergent insoluble protein (NDIP), and increased aerobic stability (AS). The highest dry matter recovery was estimated in the silages with 58% gliricidia. Based on the fermentative, chemical composition and silage losses, all the silages tested were adequate. However, considering aerobic stability, the addition of at least 25% gliricidia is recommended to provide the animal a feed with important quality and high nutritional value. |
