; Gatica Jorquera, María Carolina; Celi Mariátegui, Irma del Rosario; Guzmán Guerrero, José Luis; Zarazaga Garcés, Luis Ángel (CSIRO Publishing, 2015)
This study examines the effect of body condition score (BCS), independently of bodyweight (BW), on the onset of puberty in Blanca Andaluza female kids born in Autumn (November). Thirty-six female kids were distributed into ... -
Caracterización reproductiva de la raza caprina blanca andaluza : papel de la condición corporal, peso vivo y fotoperiodo
Gallego Calvo, María Lourdes (Universidad de Huelva, 2016)
La raza caprina Blanca Andaluza es una raza autóctona calificada como en peligro de extinción y cuenta con un reducido número de criadores, así como con una carencia casi total de datos reproductivos. Por eso, el objetivo ... -
Exogenous melatonin does not improve the freezability of Blanca Andaluza goat semen over exposure to two months of short days
Gallego Calvo, María Lourdes; Gatica Jorquera, María Carolina; Santiago Moreno, Julian; Guzmán Guerrero, José Luis; Zarazaga Garcés, Luis Ángel (Elsevier Masson, 2015)
This paper compares the effects of exposure to exogenous melatonin (MEL), short days (SD, 8 h of light) and long days (LD, 16 h of light), on reproductive activity, sperm motility and other reproductive variables, in Blanca ... -
The isolation of females from males to promote a later male effect is unnecessary if the bucks used are sexually active
Zarazaga Garcés, Luis Ángel; Gatica Jorquera, María Carolina; Hernández, H.; Gallego Calvo, María Lourdes; Delgadillo, J. A.; Guzmán Guerrero, José Luis (Elsevier, 2017)
It has been suggested that female goats in permanent contact with males become refractory to their presence, and need to be previously separated from them for 40–45 days if the presence of bucks is to induce reproductive ... -
The reproductive performance of female goats treated with melatonin is not improved after introduction to bucks displaying springtime sexual activity if these does are experiencing decreasing body weight/condition score
Zarazaga Garcés, Luis Ángel; Gatica Jorquera, María Carolina; Gallego Calvo, María Lourdes; Guzmán Guerrero, José Luis (Elsevier Masson, 2017)
The aim of the present work was to determine whether treatment with melatonin modifies the reproductive response of female goats experiencing increasing or decreasing body weight (BW)/body condition score (BCS) when ... -
Role of body condition score and body weight in the control of seasonal reproduction in Blanca Andaluza goats
Gallego Calvo, María Lourdes; Gatica Jorquera, María Carolina; Guzmán Guerrero, José Luis; Zarazaga Garcés, Luis Ángel (Elsevier Masson, 2014)
The reproductive activity of 84 female Blanca Andaluza goats was monitored over 17 months to determine the role of body condition score (BCS) and body weight (BW) in its control. Following a 3 × 2 factorial experimental ... -
Seasonal changes in reproductive activity, sperm variables and sperm freezability in Blanca Andaluza bucks
Gallego Calvo, María Lourdes; Gatica Jorquera, María Carolina; Santiago Moreno, Julian; Guzmán Guerrero, José Luis; Zarazaga Garcés, Luis Ángel (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2015)
Interest in the preservation of endangered breeds such as the Blanca Andaluza goat, has increased and some steps should be therefore taken to ensure it. The study was designed to determine the seasonal reproductive pattern ...
