The objective of this study performed in the Atlantic forest region of the South of Bahia (Brazil) was to examine the influence of the presence of the forage legume Desmodium ovalifolium in pastures of Brachiaria humidicola on the nitrogen recycled through plant litter over stocking rates of 2, 3 and 4 head ha-1. The results demonstrated that the presence of the D. ovalifolium in the pasture significantly increased the protein content of the associated Brachiaria grass, and the rate and quantity of N recycled through the litter pathway. While had no significant increase in animal weight gain due this legume, the increase in N recycled through the litter pathway should provide an increase in the sustainability of pasture production, especially at the lower stocking rate where the grazing pressure was lower and the proportion of legume was higher. |

The use of different progestin devices in ovarian stimulation protocol affects gene expression in sheep cumulus-oocyte complexes (COC). |

Conteúdo: |
Progesterone (P4) and its analogues (progestins) are commonly used in estrus synchronization protocols and to hold the LH surge during ovarian stimulation to allow oocyte recovery in live donor ewes. However, recent evidence suggests that some progestins may have a deleterious effect on embryo quality after long-term use. Thus, the present study aimed to evaluate the effect of two progestin devices used during ovarian stimulation on the COC quality in donor ewes. In conclusion, the progestin device alters the expression of genes related to quality and the steroidogenesis pathway in fully-grown COCs, and the use of a natural P4 device may improve the development competence of COCs. Further studies including IVP are necessary to confirm our findings. |
