Brazil is known for its enormous natural animal resources, typically associated with a large diversion of biomes. Although they do not originate in the country, the sheep and goats that were incorporated by settlers after the discovery became the so-called locally adapted animals. This adaptation obeyed the environmental challenges imposed, being more severe in the semi-arid zone - Caatinga biome. Similar to the African savannah, important and unique genotypes of small ruminants live in the Caatinga. Most of them are under some degree of extinction risk mainly because there is no economic interest and/or indiscriminate reproduction with commercially exploited sheep and goats around the world, such as Dorper and Boer, respectively. These specimens were included in the Brazilian Germoplasma Bank. Many genetic conservation strategies for these offspring include maintaining conservation units for a few dozen females and a few males, DNA, semen and embryos. The embryo biobank is the most viable and fastest strategy for preserving genuine specimens and rebuilding the herd, being the best option for preserving mammals in a situation of extinction. Initially, the Brazilian Bank of Embryos of Sheep and Goats was supported by the surgical recovery of embryos. Over time, after great Brazilian efforts and increases in the efficiency of non-surgical embryo recovery (NSER), the embryo bank became more pronouncedly composed of embryos of NSER origin. This document will take the reader through the history of the Brazilian Embryo Bank of Sheep and Goats with important information about the breeds included and techniques for preserving them MenosBrazil is known for its enormous natural animal resources, typically associated with a large diversion of biomes.

Sterile males (SMs) of C. capitata have been proposed as vectors of entomopathogenic fungi (EF). However, they are also susceptible to virulent strains. This work evaluates the effects of supplementing the artificial diet with antimicrobial compounds on the larvae and adults of C. capitata tsl Vienna-8 and their resistance to virulent EF strains. Even a lower dose of methylparaben (MPB) (0.5?g kg-1) inhibited the mycelial growth of Metarhizium anisopliae LCB255 and Beauveria bassiana LCB289. Sodium benzoate (BNZ) at 2.5?g kg-1 reduced mycelial growth of both strains by 50%, while citric acid did not interfere with fungi development. Supplementing the larval and adult diets with MPB (2.0?g kg-1) plus BNZ (2.5?g kg-1) or only MPB significantly reduced the mortality of pupae and adults treated with LCB255 or LCB289. Feeding larvae and adults with diets amended with the antimicrobials significantly reduced SMs? mortality and its mortality curve (p <0.05). SMs fed with the supplemented diet showed a significantly higher median survival time (8 days) than the control group (3?4 days) (p <0.05). As a result, there was an efficient transference of EF conidia to females during mating and mating attempts, thus increasing female mortality. The results were confirmed in a field-cage experiment when SMs were fed diets supplemented with antifungal compounds, which showed a higher median survival time. |
