Abstract: The aim of this study was to compare the preovulatory follicular development and superovulatory outcomes in superovulated ewes which were either stimulated or not stimulated by placement with rams. The treatment regimen to super-stimulate ovarian follicular development was imposed to 28 ewes on "Day 0", from which 14 were stimulated with active rams for 48 h, starting at the time of the fifth FSH dose, with the ram being removed from the pen with the ewes and replaced which other ram every 12 h, using four different rams (group GRE). The other 14 ewes remained isolated from rams throughout the protocol (group GCON). All ewes were administered 133 mg of FSH, into six doses in decreasing quantities, every 12 h. The follicular development and number of ovulations were determined using ultrasonography. Biostimulation resulted in an increased number of large follicles, follicle diameter, and embryo viability rate (viable embryos/recovered structures?100) was greater in ewes of the GRE than GCON group. The number of corpora lutea, follicular cysts, recovered structures, viable embryos, and degenerated and unfertilized structures was similar in ewes of the GRE and GCON group. Structures were recovered from more GRE than GCON ewes. In conclusion, biostimulation with rams during the last phase of the treatment regimen to induce superovulation enhanced the follicular growth and increased the embryo viability rate in ewes. |

The aim of this study was to assess physico-chemical fruit characteristics of 15 disease-resistant banana hybrids being evaluated by Embrapa and commercial cultivars ‘Grand Naine’ (AAA), ‘Pacovan’ (AAB) and ‘Prata Anã’ (AAB). Physical characterization included chroma, hue angle, yield, number of hands, number of fruits, bunch weight, pedicel length, pedicel diameter, peduncle weight, fruit length, fruit diameter, skin thickness, fruit length of the penultimate hand and fruit diameter of the penultimate hand. Chemical characterization included total carotenoids, reducing sugars, total sugar, titrable acidity, soluble solids, ash, moisture, protein and starch. The data were subjected to cluster analysis using the Unweighted Pair-Group Average (UPGA) method and Principal Component Analysis (PCA) from the correlation matrix. The cluster analysis showed the formation of three distinct groups. The first was formed by cultivars ‘Ambrosia’, ‘Bucaneiro’, ‘Calipso’, ‘FHIA-02’, ‘FHIA-18’, ‘BRS Maravilha’, ‘Grand Naine’ and ‘BRS Caipira’; the second was formed by ‘BRS Garantida’, ‘BRS Preciosa’, ‘BRS Japira’, ‘BRS Pacovan Ken’, ‘PV 79-34’, ‘Prata Anã’, ‘Pacovan’, ‘BRS Tropical’ and ‘BRS Platina’; and the third group was formed by ‘Thap Maeo’. The results were confirmed by PCA, where the first two components explained 47% of data variation |
