The diallel cross constitutes an informative genetic design for choosing genitors and crosses in breeding programmes since it provides estimates of general (GCA) and specific (SCA) combining abilities. Because the breeding programme for Urochloa humidicola ([Rendle] Morrone & Zuloaga; syn. Brachiaria humidicola [Rendle] Schweick) at Embrapa Beef Cattle is recent, these estimates are still unknown. Thus, the aim of this study was to obtain the estimates of GCA and SCA from the partial diallel cross design between sexual and apomictic parents. The crosses involved nine sexual and ten apomictic parents. Seventy‐one full‐sib progenies were obtained and evaluated in an incomplete block design, using all parents and the cv. BRS Tupi as a check. The agronomic and forage quality traits were evaluated using seven harvests. Statistical analysis was performed using the mixed model approach. Significant variations were associated with GCA among sexual parents for biomass yield and forage quality traits. However, this cannot be observed for apomictic parents for GCA. The SCA effect was not significant for the assessed traits. These results showed the predominance of additive effects. Sexual parents SEX3 and SEX4 presented the highest potential for contributing favourable alleles in hybrid combinations. The absence of GCA among apomictic parents and SCA suggests the need to increase genetic variability for the generation of breeding populations of U. humidicola. |

Abstract: The objective of this study, was to evaluate the exogenous FSH dose effect on gonadotrophic treatment over ewes ovulatory follicle dynamics. Twenty four Santa Inês ewes were submitted to estrus synchronization with intravaginal progesterone device (CIDR®, Pfizer, Hamilton, New Zealand) inserted on Day 0 and remaining until the Day 8. On Day 0 and Day 8 were intramuscular (IM) administered 0.125 mg of PGF2? synthetic analogue (Sincrocio®, Ouro Fino, Cravinhos, Brazil). The gonadotrophic treatment started 48 hours before the progesterone removal (Day 6) when females were randomly allocated into three experimental groups according to the total dose of exogenous porcine FSH (Folltropin-V®, Bioniche, Belleville, Canada): G200 (n = 8) - 200 mg; G133 (n = 8) - 133 mg, and G100 (n = 8) - 100 mg. Total doses were administered in eight IM injections with 12 hours intervals (20, 20, 15, 15, 10, 10, 5 and 5% of a total amount). On Day 6, the females received 300 IU of eCG IM (Novormon®, Shering-Plough S. A., Syntex S.A., Buenos Aires, Argentina). B-mode ultrasonography was performed to assess the follicular growth and ovulation moment of the ovulatory wave. The statistical analysis was performed with software R® (R Foundation for Statistical Computing, Vienna, Austria) and results were compared using the Kruskal Wallis test and Dunns posttest (P < 0.05) (mean values ± standard deviation). Rates were compared by Chi-square test. The day of emergence (6.17 ± 0.92), maximum diameter (mm; 5.96 ± 0.86), day of maximum diameter (9.38 ± 0.58), duration of growth (h; 78.76 ± 18.38), rate growth (mm/day;1.06 ± 0.30) and ovulatory diameter (mm; 5.76 ± 0.78) showed no statistical difference between the experimental groups (P > 0.05); ovulatory moment occurred later in animals from G200 (h; P = 0.0037; 45.36 ± 11.46) compared with G100 subjects (40.39 ± 12.19) and G133 (39.61 ± 11.11); preovulatory follicle size reduction and preovulatory follicle size reduction rate were greater (mm; mm/day; P = 0.0027 e 0.0024, respectively) in the G200 ewes (0.26 ± 0.38; 0.52 ± 0.77, respectively) compared with the G100 (0.13 ± 0.30; 0.25 ± 0.59, respectively), however were similar on G133 (0.23 ± 0.39; 0.46 ± 0.83, respectively). It was concluded that different exogenous FSH doses (100, 133 and 200 mg) does not interfere in the ovulatory follicle dynamics in superovulatory protocols, exception for ovulatory moment, preovulatory follicle size reduction and preovulatory follicle size reduction rate. [Efeito da dose de FSH em protocolo de superovulação sobre a dinâmica folicular ovulatória em ovelhas]. Resumo: O objetivo deste estudo foi avaliar o efeito da dose de FSH exógeno no tratamento gonadotrófico sobre a dinâmica folicular ovulatória em ovelhas. Vinte e quatro ovelhas Santa Inês foram submetidas à sincronização do estro com um dispositivo intravaginal de progesterona (CIDR®, Pfizer, Hamilton, Nova Zelândia) inserido no D0 e permaneceu até D8. No D0 e D8 foram administrados 0,125 mg de um análogo sintético da PGF2?, intramuscular (Sincrocio®, Ouro Fino, Cravinhos, Brasil). O tratamento gonadotrófico teve início 48 horas antes da retirada da progesterona (D6), quando as fêmeas foram aleatoriamente divididas em três grupos experimentais de acordo com a dose total de FSH suíno exógeno (Folltropin-V®, Bioniche, Belleville, Canadá): G200 (n=8) - 200 mg; G133 (n=8) - 133 mg; e G100 (n=8) - 100 mg. As doses totais foram administradas em 8 aplicações a intervalos de 12 horas, intramuscular (20, 20, 15, 15, 10, 10, 5 e 5% de FSH). No D6, as fêmeas receberam 300 UI de eCG, intramuscular (Novormon®, Shering-Plough S. A., Syntex S.A., Buenos Aires, Argentina). Foram realizadas avaliações ultrassonográficas (Modo B) com o propósito de acompanhar o crescimento folicular e o momento da ovulação da onda ovulatória. A análise estatística foi realizada com o software R® (R Foundation for Statistical Computing, Vienna, Austria) e os resultados foram comparados pelo teste de Kruskal Wallis e pós-teste de Dunns (P < 0,05) (valores médios ± desvio padrão). As taxas foram comparadas pelo teste Chi-quadrado. O dia da emergência (6,17 ± 0,92), diâmetro máximo (mm; 5,96 ± 0,86), dia do diâmetro máximo (9,38 ± 0,58), duração de crescimento (h; 78,76 ± 18,38), taxa de crescimento (mm/dia;1,06 ± 0,30) e diâmetro ovulatório (mm; 5,76 ± 0,78) não apresentaram diferença estatística entre os grupos experimentais (P > 0,05); momento ovulatório ocorreu tardiamente nos animais pertencentes ao G200 (h; P = 0,0037; 45,36 ± 11,46) em relação ao G100 (40,39 ± 12,19) e G133 (39,61 ± 11,11); redução do tamanho do folículo pré-ovulatório e taxa de redução do tamanho do folículo pré-ovulatório foram maiores (mm; mm/dia; P = 0,0027 e 0,0024, respectivamente) para ovelhas do G200 (0,26 ± 0,38; 0,52 ± 0,77, respectivamente) em relação ao G100 (0,13 ± 0,30; 0,25 ± 0,59, respectivamente), entretanto semelhante ao G133 (0,23 ± 0,39; 0,46 ± 0,83, respectivamente).
