To study Lidia cow reproductive apparatus traits, a total of 90 organs were collected after slaughtering the cows from different Bos taurus breeds: (i) Lidia cattle breed - Brava dos Açores population (n=10) and Domecq lineage (n=11); (ii) Holstein Friesian females – 10-14-month-old heifers (n=15); 15-20-month-old heifers (n=10), 21-19-month-old heifers (n=18), and (iii) cows ≥ 30 months (n=26). The length and width were measured for five portions of the female reproductive apparatus (vulva and vagina, cervix, uterine body, uterine horns and ovaries). One-way ANOVA was performed with Tukey test. The level recognized to assume differences was p<0.05 to less. Differences were not shown between Lidia groups. In general, the Lidia cow reproductive apparatus was small in size that that of the matured cows in terms of all traits, with the exception of cervix rings (5.10 ± 0.17 rings) with p≤0.01 for all the groups (averages ranged from 3.33 ± 0.11 rings to 3.50 ± 0.15 rings). The vulva and vagina (L= 27.31 ± 0.53 cm; W=2.07 ± 0.14 cm), the uterine body width (3.01 ± 0.18 cm) and the uterine horns (L= 12.24 ± 0.32; W= 1.13 ± 0.10) showed were smaller in size than those of the evaluated heifers from HF breed that ranged in age from 10 to 14 months (p≤0.01). This study was the first to perform a morphometric characterization on the Lidia cow reproductive apparatus, and the results provide useful information for understanding reproductive approaches to be used with this breed.
Mycobacterium avium subspecies paratuberculosis (MAP) causes paratuberculosis, also known as Johne's disease, in domestic ruminants and wild species, resulting in economic losses among farmed ruminants. In Portugal, the true herd-level prevalence of paratuberculosis is unknown and the disease is considered under diagnosed. Particularly in the Azores only a very few studies were developed reporting this infection considering the potential loss in milk production. The aim of the present study is to evaluate the incidence of bovine paratuberculosis in a Lidia bovine population called "Brava dos Acores", destined to the typical Azorean street bullfighting as well as the traditional equestrian bullfight (in the ring). For such purpose, 68 animals belonging to that bullfight population mainly females (n= 55 vs 13 males) aged between 7 to 223 months were submitted to a blood collection, via the coccygeal vein, for diagnostic of paratuberculosis through the Elisa diagnostic test. Results showed that, from the 68 studied animals, 63 were negative for the presence of Paratuberculosis, 4 were positive and 1 was doubtful. The percentage of infected animals with positive and doubtful animals was 7.4%.In addition to the new knowledge obtained, it was concluded that further studies on this breed will be essential to expand the existing information.
