    • Early pregnancy diagnosis in alpaca (Lama pacos) and llama (Lama glama) by ultrasound 
      Parraguez Gamboa, Víctor; Cortéz, Sandra; Gazitúa, Francisca; Ferrando Ratto, Germán; MacNiven Rengifo, Verónica; Raggi Saini, Luis (1997)
      An ultrasonography study of early pregnancy diagnosis was carried out in 19 alpacas and 12 llamas, after controlled matings. The aim was to determine the earliest gestational age at which pregnancy diagnosis by transrectal ...
    • Expression of vascular endothelial growth factor and endothelial nitric oxide synthase is increased in the ... 
      Parraguez Gamboa, Víctor; Miljenko, Atlagich; Urquieta, Bessie; Galleguillos, Marco; Reyes Solovera, Mónica de los; Kooyman, David L.; Araneda, Silvia; Raggi Saini, Luis (CANADIAN VET MED ASSOC, 2010-07)
      Fetal weight and the placenta of sheep at high altitude (HA) are affected by hypoxia. Placental changes (an increase in placental size and vascularization) are greater in ewes from populations that have lived for several ...
    • Feeding and foraging behaviour of alpaca in northern Chile 
      Raggi Saini, Luis; Jiliberto, E.; Urquieta Mangiola, Bessie (1994)
      Alpaca play a primary role in the Andean peasant economy. Major constraints to productivity include lack of knowledge of relations between reproduction and nutrition and of the potential of alpaca outside their normal ...
    • Ovine placenta at high altitudes: Comparison of animals with different times of adaptation to hypoxic environment 
      Parraguez Gamboa, Víctor; Atlagich, Miljenko; Díaz, Rodrigo; Cepeda, Raquel; González, Carlos; Reyes Solovera, Mónica de los; Bruzzone Valdés, María Eugenia; Behn Thiele, Claus; Raggi Saini, Luis (ELSEVIER, 2006-09)
      Fetal growth and newborn weight from ovine gestations at high altitudes (HA) are greater in ewes that live at HA for several generations than in those native to low altitudes (LA) exposed to HA only during pregnancy. Because ...
    • Plasma progesterone in alpaca (Lama pacos) during pregnancy, parturition and early postpartum 
      Raggi Saini, Luis; Ferrando, Germán; Parraguez Gamboa, Víctor; MacNiven, Verónica; Urquieta, Bessie (ELSEVIER SCIENCE BV, 1999-01-29)
      Plasma progesterone concentration during pregnancy and the early postpartum period was measured by radioimmunoassay in five alpacas (Lama pacos), of the Huacaya breed, whose pregnancy length had a mean of 344.8 +/- 4.4 ...
    • Prediction of gestational age by ultrasonic fetometry in llamas (Lama glama) and alpacas (Lama pacos) 
      Gazitúa, Francisca J.; Corradini Rojas, Paulina; Ferrando Ratto, Germán; Raggi Saini, Luis; Parraguez Gamboa, Víctor (2001)
      Fetal biparietal diameter (BPD) and thorax height (TH) were measured by ultrasound during intrauterine growth in pregnant llamas (Lama glama) and alpacas (Lama pacos). The goal was to establish representative curves that ...
    • Secreción biliar en el cabrito lactante anestesiado. Efectos de la administración exógena de secretina y ... 
      Raggi Saini, Luis; Crossley C., Jorge; Albala B., Alejandro; Lazo A., Walezca (Universidad de Chile, 1988)
      El objetivo del presente trabajo es estudiar el efecto de la administracion exogena de secretina y CCK-PZ sobre el flujo y composicion de la bilis en el cabrito lactante anestesiado. Se utilizaron 20 cabritos lactantes de ...
