Abstract: The aim of this study was to verify the efficacy of reusing intravaginal progesterone (P4) devices on the reproductive parameters in Santa Inês ewes. Females received intravaginal P4 devices for their first, second or third use for five days plus 300 IU eCG IM and 5mg dinoprost laterovulvar 24h before device removal. Blood was collected at different moments. Transrectal ultrasonography was performed from device removal to ovulation. Part of the ewes were submitted to artificial insemination by laparoscopy (IAL - n=55) with fresh semen, whereas the rest were bred by fertile rams (n=41). On the initial 18 h, ewes that received devices for the first time showed higher P4 concentrations (5.1±1.8 vs 3.5±1.4 vs 2.4±1.1 - P<0.05). However, after the first 48h no difference was observed among all treatments and P4 supraluteal concentrations were detected in all ewes upon device removal. Estrous response, interval from device removal to estrus, rate of ovulating animals, number of ovulations, time from device removal to ovulation and average conception rates after IAL or natural mating were similar among all 3 groups. Intravaginal progesterone devices can be used up to three times without altering reproductive parameters in Santa Inês ewes. Características reprodutivas de ovelhas Santa Inês que receberam dispositivos de progesterona reutilizados. Resumo Avaliou-se a eficácia da reutilização de dispositivos intravaginais de progesterona (P4) sobre características reprodutivas em ovelhas Santa Inês. As fêmeas receberam dispositivos intravaginais contendo P4 para o seu primeiro, segundo ou terceiro uso por cinco dias, associado a 300 UI eCG IM e 5mg dinoprost laterovulvar 24h antes da remoção dos dispositivos. Ultrassonografia transretal foi realizada da remoção dos dispositivos até a ovulação. Parte das ovelhas foi submetida à inseminação artificial laparoscópica (IAL? n=55) com sêmen a fresco, enquanto outra parte foi acasalada por machos férteis (n=41). Nas 18 h iniciais, as ovelhas que receberam dispositivos pela primeira vez apresentaram maior concentração de P4 (5.1±1.8 vs 3.5±1.4 vs 2.4±1.1 ? P<0.05). Entretanto, após as primeiras 48h nenhuma diferença foi observada entre os tratamentos quanto as concentrações circulantes de progesterona. Foram encontradas concentrações de progesterona supraluteais em todas as ovelhas na retirada dos dispositivos. Estro, intervalo da retirada ao estro, taxa de animais que ovularam, número de ovulações, momento da retirada à ovulação e taxa média de concepção após IAL ou monta natural foram similares entre os tratamentos. Dispositivos intravaginais de progesterona podem ser usados até três vezes sem alterar as características reprodutivas de ovelhas Santa Inês.

The addition of co-substrates as adjuvants to the bioremediation process enables almost complete removal of the polycyclic aromatic hydrocarbons (PAH) in the soil. The aim of this work was to associate biostimulation and bioaugmentation, represented respectively by the addition of residues from the processing of three oilseeds, and by the addition of consortia formed by Pseudomonas aeruginosa and Burkholderia cepacia strains, in the removal of phenanthrene and pyrene from a soil contaminated by a lubricating oil mixture containing approximately 50 mg/kg PAH. Three consortia were prepared from antimicrobial activity tests and each was stimulated with cotton, peanut or sesame cakes (20 and 40 mg/kg). The biodegradation tests were carried out on polyethylene reactors filled with 200 g of sandy soil. After 60 days incubation at room temperature, between 65 and 80% of the phenanthrene and pyrene was removed with preferential degradation of the three consortia by pyrene. In all cases, the most successful condition was obtained when the cake contents were added, independent of amount of contaminant content (40 or 80 mL/kg), emphasizing the importance of the use of co-substrate and reuse of agro-industrial wastes in bioremediation. Phytotoxicity assays demonstrated that Zea mays was the best indicator of soil fertility after treatment. |
