“…Average values obtained in Carthusian mares were shorter than those obtained in different breeds such as, Thoroughbreds (Hintz et al 1992, Davies-Morel et al 2002, Kurtz Filho et al 1997, Duggan et al 2008, Sharma and Dhaliwal 2010, Freibergers (Giger et al 1997), Lipizzaners (Heidler et al 2004), Quarter Horses (Pool-Anderson et al 1994, Guay et al 2002, Duggan et al 2008), Hannoverians (Winter et al 2007), Pantaneira (Zúccari et al 2002), Andalusians (Valera et al 2006) and Arabians mares (Valera et al 2006, Cilek 2009). …”

“…Geographic area, climate, day length and environmental temperatures might partially explain the differences observed in GLs in the different investigations since that regions of similar latitudes, have similar GLs and are affected by similar factors (Kurtz Filho et al 1997, Davies-Morel et al 2002, Winter et al 2007). We have found that the shortest GL in the Carthusian broodmares appear when the animals were mated between May and July.…”

“…Indeed, several authors failed to detect differences in GL when comparing mares of different ages (Hintz et al 1992, Kurtz Filho et al 1997, Davies-Morel et al 2002, Guay et al 2002, Pérez et al 2003, Winter et al 2007.…”

The length of gestation in Carthusian broodmares was calculated on the basis of 339 spontaneous full-term deliveries taking place in the 8-year period 1998-2005 from 158 broodmares and 29 stallions in a major farm of Spanish horses of Carthusian strain in southern Spain. Ultrasonography was used to determine follicular dehiscence, 1 st day of pregnancy and to confirm conception in mares. Mean GL was 332.4 ± 12

“…In the literature, gestational length has been reported for Thoroughbred (Allen et al, 2002;Davies Morel et al, 2002;Duggan et al, 2008;Elliott et al, 2009), American Quarter Horse (QH; Duggan et al, 2008), Criollo (Winter et al, 2007), Pantaneiro Horse (Zuccari et al, 2002), Lusitano (Pérez et al, 2003;Valera et al, 2006) and Arabian (Valera et al, 2006) mares. In all of these studies, the mean gestational length ranged between 330 and 350 days (Satué et al, 2011a).…”

Factors affecting gestational length in the Mangalarga Paulista breed

The Mangalarga Paulista is a Brazilian horse breed that originated from a cross between Andalusian and Alter Real horses, and despite its national importance, no data exist regarding their gestational length. This study was conducted to determine the variation in gestation length and the influence of factors such as the sex of the foal, maternal age and parity, stallion and mating period. Retrospectively, data from 208 gestations of Mangalarga Paulista foals located in Piracaia, SP, Brazil, during the period from 1991 to 2012 were analyzed. The mean gestational length was 343.08 ± 0.66 days, with a range between 317 and 404 days. Gestation of mares carrying colts had a tendency to be longer than mares carrying fillies. Maternal parity significantly affected gestational length, with longer gestation for primiparous mares until the third gestation, shorter pregnancies between 4th and 8th gestation, and longer thereafter. Regarding mating period, mares that were mated at the end of the breeding season (January and February) had shorter pregnancies (P < 0.05). These results are of significant clinical and economic relevance for the equine industry, so that the monitoring of gestation and parturition can be performed effectively.
