      Background: During decades, dairy cows have been selected for its productive character, with the main focus on the breeding production, being submitted to constant conditions of metabolic disorders, likewise submitted to ...

    • Insertion of an intrauterine catheter for post-cervical artificial insemination in gilts : a case report 

      Ulguim, Rafael da Rosa; Vier, Carine Mirela; Betiolo, Felipe Basquera; Sbardella, Pedro Ernesto; Bernardi, Mari Lourdes; Wentz, Ivo; Mellagi, Ana Paula Gonçalves; Bortolozzo, Fernando Pandolfo (2018) [Artículo de periódico]
      The aim of this case report was to characterize the insertion of an intrauterine catheter (IC) in gilts to perform post-cervical artificial insemination (PCAI). Attempts to insert ICs through the cervixes of gilts were ...

    • Managing reproduction in hyperprolific sow herds 

      Bortolozzo, Fernando Pandolfo; Zanin, Gabriela Piovesan; Ulguim, Rafael da Rosa; Mellagi, Ana Paula Gonçalves (2023) [Artículo de periódico]
      The rearing of large litters from hyperprolific sows is a characteristic of modern genotypes. However, these sows have body and reproductive characteristics that differentiate them from the genotypes of the past decades, ...

    • Perspectives of intrauterine artificial insemination applicability in gilts 

      Will, Kelly Jaqueline; Mellagi, Ana Paula Gonçalves; Bernardi, Mari Lourdes; Bortolozzo, Fernando Pandolfo; Ulguim, Rafael da Rosa (2021) [Artículo de periódico]
      The application of the intrauterine artificial insemination (IUAI) technique allows optimization of a swine production system due to the reductions in volume and number of sperm cells in the insemination dose, and by ...

    • Porcine luteinising hormone given at oestrus onset by intramuscular route does not advance ovulation in gilts 

      Ulguim, Rafael da Rosa; Sbardella, Pedro Ernesto; Fontana, Diogo Luiz; Moroni, Júlia Linck; Pommerehn, Luíza; Bernardi, Mari Lourdes; Wentz, Ivo; Bortolozzo, Fernando Pandolfo (2015) [Artículo de periódico]

      Background: Body condition score is used widely in swine production to ensure adequate nutritional levels in sows during gestation and lactation. However, body condition score is not a gold standard for the estimation of ...

    • Reproductive performance of fixed-time artificial insemination in swine and factors for the technology success 

      Quirino, Monike; Pinheiro, Ana Raquel Almeida; Santos, Joabel Tonellotto dos; Ulguim, Rafael da Rosa; Mellagi, Ana Paula Gonçalves; Bortolozzo, Fernando Pandolfo (2019) [Artículo de periódico]
      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 ...

    • Reproductive performance of single fixed-time inseminated sows with semen doses submitted to different semen storage times
