| The objective of this study was to determine the effects of GDF-9, IGF-I, and GH alone or combined on preantral follicle survival, activation and development after 1 and 7 days of in vitro culture. Either fresh (non-cultured) or cultured ovarian tissue was processed for histological and fluorescence analysis. For all media tested, the percent of normal follicles was greater when compared to minimum essential medium supplemented (MEM+) alone, except when ovarian tissue was cultured with GDF-9/IGF-I or GDF-9/GH (P < 0.05). Fluorescence analysis showed that the percent of viable follicles after 7 days of culture was similar for non-cultured tissue and for all treatments tested. The percent of primordial follicles was reduced (P < 0.05) and there was a... |

| Abstract: The objective of this work was to describe the effect of genetic composition on body condition score (BCS), on total lactation production, and on metabolic and hormone profiles of Holstein x Gyr cows under the same pre- and postpartum management conditions. The genetic groups ½ (n=8), – (n=10), and ≥⅞ (n=10) Holstein x Gyr (HG) were evaluated within the same farm, and all of them showed typical lactation curves. The time required to reach peak production did not differ between groups. The groups also did not differ as to time to reach the lowest BCS after calving or to recover BCS after calving, nor as to their BCS values in the week of first ovulation, number of weeks required for first ovulation, and service period. However, ½ HG cows had... |

| Avaliou-se o efeito da somatotropina bovina recombinante (rbST) sobre a qualidade do corpo lúteo e do embrião e sobre a concentração de progesterona (P4), em ovelhas da raça Santa Inês doadoras de embriões. Foram utilizadas 13 doadoras, distribuídas aleatoriamente em dois grupos, G1 (n=7) e G2 (n=6). Em ambos os grupos, as doadoras foram sincronizadas com implante vaginal por 14 dias, receberam 100µg de PGF2α (Ciosin®) no sétimo dia e foram superovuladas, a partir do 12º dia, com 250UI de FSH (Folltopin-V®) em seis doses decrescentes. No dia da retirada do implante, as doadoras do G2 receberam 125mg de rbST (Boostin®) e foram cobertas por macho Santa Inês a cada 12 horas até o final do estro. No sexto dia após a primeira cobrição, foram avaliadas, por... |

| Tibetan (TB) and Bama (BM) miniature pigs are two popular pig breeds that are used as experimental animals in China due to their small body size. Here, we analyzed single-nucleotide polymorphisms (SNPs) in gene fragments that are closely related to growth traits [growth hormone (GH), growth hormone receptor (GHR), and insulin-like growth factor (IGF)-1)] in these pig breeds and a large white (LW) control pig breed. On the basis of the analysis of 100 BMs, 108 TBs, and 50 LWs, the polymorphic distribution levels of GH, GHR, and IGF-1 were significantly different among these three pig breeds. According to correlation analyses between SNPs and five growth traits - body weight (BW), body length (BL), withers height (WH), chest circumference (CC), and abdomen... |
