    • Chronic Neospora caninum infection and repeat abortion in dairy cows: a 3-year study 

      Pabón, M.; López Gatius, Fernando; García Ispierto, Irina; Bech Sàbat, Gregori; Nogareda, Carmina; Almería, S. (Elsevier, 2007)
      The serological status of Neospora was monitored in animals older than 6 months in a dairy herd with a 3-year history of prevalent N. caninum and N. caninum-associated abortions. The numbers of animals in the herd tested ...
    • Climate factors affecting conception rate of high producing dairy cows in northeastern Spain 

      García Ispierto, Irina; López Gatius, Fernando; Bech Sàbat, Gregori; Santolaria Blasco, Pilar; Yániz Pérez de Albéniz, Jesús; Nogareda, Carmina; De Rensis, F.; López-Béjar, M. (Elsevier, 2007)
      Summer heat stress is a main factor related to low conception rate in high producing dairy herds in warm areas worldwide. We assessed the impact of several climate variables on conception rate in high producing dairy cows ...
    • Dynamics of anti-Neospora caninum antibodies during gestation in chronically infected dairy cows 

      Nogareda, Carmina; López Gatius, Fernando; Santolaria Blasco, Pilar; García Ispierto, Irina; Bech Sàbat, Gregori; Pabón, M.; Mezo, M.; Gonzalez-Warleta, M.; Castro Hermida, J. A.; Yániz Pérez de Albéniz, Jesús; Almería, S. (Elsevier, 2007)
      The dynamics of antibody production against Neospora caninum during the gestation period was examined in chronically infected dairy cows. Data were obtained from 86 pregnant parous dairy cows, 21 of which had suffered ...
    • Early postabortion recovery of Neospora-infected lactating dairy cows 

      Santolaria Blasco, Pilar; López Gatius, Fernando; Yániz Pérez de Albéniz, Jesús; García Ispierto, Irina; Nogareda, Carmina; Bech Sàbat, Gregori; Serrano, Beatriz; Almería, S. (Elsevier, 2009)
      This study was designed to assess the reproductive performance of Neospora caninum–infected dairy cows (Bos taurus) after abortion. The population examined was composed of 92 aborting cows subsequently subjected to at ...
    • Effects of crossbreed pregnancies on the abortion risk of Neospora caninum-infected dairy cows 

      Almería, S.; López Gatius, Fernando; García Ispierto, Irina; Nogareda, Carmina; Bech Sàbat, Gregori; Serrano, Beatriz; Santolaria Blasco, Pilar; Yániz Pérez de Albéniz, Jesús (Elsevier, 2009)
      Previous studies have shown that the use of beef bull semen significantly reduces the rate of abortions due to Neospora caninum in artificially inseminated (AI) seropositive dairy cows. In addition, certain beef breeds ...
    • Factors affecting the response to the specific treatment of several forms of clinical anestrus in high producing dairy cows 

      López Gatius, Fernando; Mirzaei, A.; Santolaria Blasco, Pilar; Bech Sàbat, Gregori; Nogareda, Carmina; García Ispierto, Irina; Hanzen, Ch.; Yániz Pérez de Albéniz, Jesús (Elsevier, 2008)
      This study was designed to examine estrous response rates to the therapeutic treatment of clinical anestrus in high producing dairy cows and to identify the factors that could affect these rates. Cows with silent ovulation ...
    • Progesterone supplementation during mid-gestation increases the risk of abortion in Neospora-infected dairy cows with high antibody titres 

      Bech Sàbat, Gregori; López Gatius, Fernando; Santolaria Blasco, Pilar; García Ispierto, Irina; Pabón, M.; Nogareda, Carmina; Yániz Pérez de Albéniz, Jesús; Almería, S. (Elsevier, 2007)
      Progesterone has been reported to reduce Th1 responses during pregnancy. Thus, given that an excessive Th1 response could lead to abortion in Neospora-infected dairy cows, we hypothesized a reduction in abortion risk ...
    • Some factors affecting the abortion rate in dairy herds with high incidence of Neospora-associated abortions are different in cows and heifers 

      García Ispierto, Irina; Bech Sàbat, Gregori; Serrano, Beatriz; Nogareda, Carmina; Almería, S.; Santolaria Blasco, Pilar; López Gatius, Fernando; Yániz, J. L.; Sanchez Nadal, J. A. (Blackwell, 2010)
      The aim of this study was to determine if the factors affecting the abortion rate in dairy herds with high incidence of Neospora-associated abortions are different in pregnancies of cows and heifers chronically infected ...
