“…Previous studies have indicated that most Curraleiro herds and animals are found in the states of Tocantins and Goiás (Fioravanti et al, 2011). In contrast, the ABCBCP indicated that the state of Piauí has the most herds and animals (Personal communication with Fernando Gayoso).…”

“…Curraleiro originated from an admixture of the three Bos taurus ibericus breeds, Alentajana, Galega and Mirandesa, whose introduction to Brazil, from Spain, Portugal and the Cape Verde Islands started in the first half of the sixteenth century (Primo, 1992;Britto and Mello, 1999;Rangel, Zucci and Ferreira, 2004;Mariante and Cavalcante, 2006). It developed initially in the states of Pernambuco, Sergipe, Alagoas, Paraíba, Ceára, Maranhão and Piauí, and also spread to the north into the state of Pará and to the southwest into the states of Tocantins and Goias (Britto and Mello, 1999;Carvalho et al, 2010;Fioravanti et al, 2011). Today, the Curraleiro is the only naturalized bovine breed in Northeastern Brazil (Figure 2), a large territory of about 980 000 km 2 mainly dominated by the Caatinga, a semiarid bush-savannah characterized by a mean precipitation of 900 mm/year, high levels of evaporation and relative humidity that is sometimes lower than 30 percent during the dry season (Bianchini et al, 2006).…”

“…Despite the low costs of breeding the Curraleiro, and its good adaption to local environmental conditions, the absence of artificial selection has been accompanied by low economic efficiency (Fioravanti et al, 2011). In order to intensify agricultural production, more productive European and (mainly African) zebu breeds were introduced to Brazil and started to displace the Curraleiro at the end of the nineteenth century Egito et al, 2007;Oliveira, 2008).…”

The Curraleiro, also called Pé-Duro, is the only naturalized bovine breed of Northeastern Brazil. The breed originated via admixture of different Iberian breeds that were introduced during the sixteenth century and the subsequent natural adaptations to the semi-arid environment. The introduction of zebu bovine breeds during the twentieth century led to the replacement of the Curraleiro, which is now on the brink of extinction. With the aim of supporting the establishment of a conservation programme, the present study focused on assessing the management of the existing Curraleiro populations. Data on 2 366 head of cattle were obtained by interviewing 22 owners of Curraleiro herds. The number of animals in the herds varied from 4 to 384. The average herd size was 131.4 (standard deviation = 120.3). All animals were bred under extensive conditions, without any supplementary feed, and in 50 percent of all cases without any specialized technical assistance. Data indicated that breeders maintain the cattle not for economic reasons, but because of tradition. The Curraleiro was characterized by the breeders as being resistant to water stress and parasites. The animals can be bred without feed supplements on all kinds of native-grass pastures. These characteristics, in addition to its low production costs, could make the Curraleiro attractive, especially for low-income families. RésuméLe bétail Curraleiro, aussi appelé Pé-Duro, représente la seule race bovine naturalisée du Nord-est du Brésil. La race s'est formée suite au croisement de différentes races ibériques introduites au cours du seizième siècle et par l'adaptation naturelle à l'environnement semiaride. Les races zébuines introduites pendant le vingtième siècle ont remplacé la race Curraleiro qui se trouve actuellement au bord de l'extinction. Afin de soutenir l'établissement d'un programme de conservation, cette étude s'est concentrée sur la caractérisation de la conduite des élevages de race Curraleiro encore existants. Les données de 2 366 animaux ont été obtenues en enquêtant 22 propriétaires de troupeaux Curraleiro. Le nombre d'animaux par exploitation a varié de 4 à 384. La taille moyenne des troupeaux était de 131,4 avec un écart type de 120,3. Tous les animaux ont été élevés dans des conditions extensives, sans aucun complément alimentaire, et dans le 50 pour cent des cas sans aucune assistance technique spécialisée. Les données indiquent que les éleveurs maintiennent la race non pas pour des raisons économiques mais par tradition. Les éleveurs ont souligné que la race Curraleiro est résistante au manque d'eau et aux parasites. Les animaux peuvent être élevés, sans aucune supplémentation alimentaire, sur la base de n'importe quel pâturage natif. Ces caractéristiques, liées aux faibles coûts de production, pourraient rendre la race Curraleiro attirante, en particulier pour les familles à faibles revenus.

Tropically adapted Bos taurus breeds are descended from the cattle which were brought from the Iberian Peninsula to Latin America by the colonizers and which adapted over time to local conditions. These breeds have become a genetic treasure that must be preserved. The objective of this study was to characterize ovarian follicular emergence and divergence in tropically adapted B. taurus cows and heifers. Cyclic heifers (n = 11) and nonlactating, multiparous cows (n = 11) were examined at 8-hour intervals using ultrasonography starting on the day following the final application of PGF, which was used to synchronize the estrous cycle, and ending 5 days after ovulation. Blood samples were collected immediately following the ultrasonographic examinations in order to evaluate FSH and estradiol-17β (E) concentrations. The interval between ovulation and follicular wave emergence (11.6 ± 3.3 hours vs. 20.3 ± 2.5 hours, P < 0.05) and ovulation and follicular wave divergence (52.4 ± 5.2 hours vs. 71.8 ± 4.1 hours, P < 0.05) was shorter in the cows than in the heifers, respectively. Plasma FSH concentrations increased (P < 0.05) and serum E concentrations decreased earlier in cows than in heifers before ovulation. Following follicular wave emergence, no difference in follicular development was found between the cows and the heifers. Consequently, following follicular wave emergence, the data from both the cows and the heifers were combined and categorized by dominant follicle (DF) and second largest follicle (SF). The DF and SF were identified at the same time (P > 0.05). The mean number of small (≤4 mm, 7.2 ± 5.1) and medium (4 to ≤ 8 mm, 6.8 ± 3.5) follicles was greater than that of large follicles (≥8 mm, 0.6 ± 0.5) from ovulation until 5 days after ovulation. The DF diameter (8.1 ± 1 mm) did not differ (P = 0.09) from SF diameter (7.6 ± 0.9 mm) at the time of follicular divergence (around 45 hours after follicular emergence). The DF and SF growth rates were similar (P > 0.05) until follicular divergence, at which point the SF growth rate decreased, whereas the DF growth rate remained constant. Serum E concentrations did not change (P > 0.05) during the divergence period, whereas FSH concentrations decreased between 48 and 32 hours before follicular wave divergence. In conclusion, cows and heifers differed only in the interval from ovulation to follicular wave emergence and divergence, which was confirmed by the different patterns of FSH and E concentrations.
