| RESUMO O objetivo do presente estudo foi investigar a ocorrência da síndrome do segundo parto em uma granja comercial de suínos e apresentar alternativas para minimizar esse problema reprodutivo. Os dados foram obtidos de 363 fêmeas de genética comercial (DB-30) de primeiro e segundo partos, entre os anos de 2010 e 2011. Os animais pertenciam a uma granja comercial de ciclo completo com 1200 matrizes, cujos índices zootécnicos não permitiam detectar a presença da síndrome do segundo parto. O período de lactação foi de 24,6±3,3 dias. Foram analisados o número de nascidos totais e nascidos vivos, o peso da leitegada ao nascimento, o número de desmamados e o peso ao desmame do lote e também individualmente de cada marrã ao longo do ano. As médias e o... |

| A study was conducted in 24 gilts to determine the effect of Trypanosoma brucei infection on their reproductive efficiency. The infected gilts developed clinical trypanosomosis following a prepatent period of 2-3 days with 1.8 x 10⁶ trypanosomes per gilt. The clinical signs were observed intermittent fever, pale mucus membranes, short moist cough, moist rales, mucopurulent ocular discharges and hyperemia of the skin, reduced feed intake, and loss of body condition, recumbency, uncoordinated movements, posterior paresis and death of gilts. The cause of death in the pigs was pneumonia caused by Escherichia coli. Grossly, the lungs were severely congested and had undergone gray hepatization. Histopathologically, the lungs had thickened and congested alveolar... |

| ABSTRACT: Fixed-time artificial insemination (FTAI) is a reproductive technology that aids in obtaining an appropriate time to perform single artificial insemination (AI), thus reducing the number of inseminations per sow bred. FTAI protocols can either be based on estrus detection or day of weaning, aiming to synchronize ovulation using ovulation inducers. The protocols involving estrus detection usually employ porcine luteinizing hormone (pLH) as an inducer and, in general, satisfactory reproductive performance is observed. For protocols based on weaning day, the main hormone used is analog of gonadotropin-releasing hormone such as triptorelin and buserelin. Regardless of the protocol, the number of piglets born is usually not affected by FTAI. However,... |
