“…Previously, the clustering of cattle breeds based on genetic distance and the genetic tree was commonly performed using Bos taurus and Bos inducus (Chung, 2013;Xuan et al, 2010), since reference related to Bali cattle as Bos javanicus cluster has been scarcely available. Genetic diversity of cattle breeds could be researched not only according to partial fragment of D-loop mtDNA (Correia et al, 2017;Sari et al, 2016), complete fragment of dloop mtDNA (Lorenzo et al, 2018), but also whole sequence of mtDNA genome (Pramod et al, 2018). Yet, it is noteworthy that the results of the analysis using entire fragments are expected to collect comprehensive relationships between individuals within species or among species closely related with divergence time (Rehman et al, 2017).…”

This study aimed to investigate the diversity of the complete sequence of D-loop mitochondrial DNA (mtDNA) in Bali and Sumba Ongole (SO) cattlebreeds. A total of 24 blood samples were collected from Bali cattle (19 heads) and SO cattle (5 heads), and were extracted and then analyzed to obtain the sequence of D-loop mt DNA.Multiple alignments of the whole sequence of D-loop mtDNA were determined using clustal W. Genetic distance was calculated using a p-distance method, while the genetic tree was constructed using neighbor-joining (NJ) based on MEGA 6. Haplotype number, haplotype diversity (Hd) and nucleotide diversity (Pi) were analyzed using DnaSP version 6. As a result, the sequence of D-loop mtDNA in Bali cattle (921-1119 bp) and SO cattle (913 bp) was reported to have 8 and 4 haplotypes. Hd and Pi of Bali cattle reached 0.625±0.139 and 0.0266±0.0145, respectively, which wwere different from that of SO cattle, namely 0.900±0.1610 and 0.0064±0.0015, respectively. Specifically, we found 22 bp-repetitive nucleotide in Bali cattle, existing 3-9 times with a length of 66-198 bp present in D-loop mtDNA. This unique feature did not exist in SO cattle. Genetic distance and genetic tree determined according to sequence in hypervariability (HV-1) region of D-loop mtDNA (166 bp) resulted in satisfied separation, successfully classifying Bos javanicus, Bos indicus, and Bos taurus cluster.

“…interfere with baseline temperament expression (Tucker et al 2015). In a previous study carried out by our research group, the value of blood cortisol, measured together with rectal temperatures and eye infrared thermography, was 7.77 ± 0.38/dl of plasma (Correia, 2017). These samples were collected from Lidia breed cows after passing through the cattle chute on the day of artificial insemination, without previous habituation.…”

The present study was designed to assess the effect of stress on the reproductive performance of cattle. For this purpose, a total of 137 cows were divided into two groups: 65 belonging to the Azores Lydia breed and 72 crossing Aberdeen-Angus with Limousine, free of IBR, Chlamydia and BVD diseases and with a body condition score ranging from 2.75 to 4.0. Eight days before starting the experimental procedures, animals passed through the containment sleeve every other day for routine and human presence. For the synchronization protocol, a progesterone-impregnated controlled internal drug release (CIDR®) insert was placed intravaginally, and an injection of GnRH was given. After 7 days, PGF2α was administered, and the CIDR® was removed. Sixty hours after removal, cows were inseminated once after another injection of GnRH to induce ovulation, and pregnancy diagnosis was performed by ultrasonography 30 days after artificial insemination. Peripheral blood was collected in 5 ml tubes with a Z Serum Sep Clot Activator, and cortisol was measured using the IMMULITE 2000 Immunoassay System ®. Our results indicated significant differences (p≤0.05) in the cortisol levels among both groups (beef crossbred cows vs Azores Lydia) of 4.3±0.3 ng/dl and 5.8±0.4 ng/dl, respectively. The pregnancy results were also significantly different: 63.7% vs 45.6%, respectively, for beef crossbred and "Azores Lydia" cows. The present study clearly demonstrated a negative correlation between cortisol levels and pregnancy rates after fixed-time artificial insemination. The low levels of cortisol observed in the animals and particularly in the Azores Lydia breed, when compared to other studies carried out on these animals, must be due to the passage of the animals in the sleeve, allowing them to habituate to a routine, as well as to human presence.

“…There are authors who claim that, arrived in the Iberian Peninsula from North Africa through the Strait of Gibraltar [2]. Nowadays the Lidia bovine breed is mainly distributed in the west and southwest of Spain, Portugal, south of France, and in South America [3] The arrival of bovines in the Azores began in the 15th century with the colonization of the islands, by the Portuguese population. Also, at the beginning of the 20th century, different Lidia lineages, that also included the "Casta Portuguesa", began to be selected on Terceira Island (Azores) for a cultural event called "Tourada à Corda" [4][5][6].…”

In Terceira Island -Azores -Portugal, agriculture and particularly the livestock sector is the mainstay of the economy, employing more than 50% of the total population. Besides the major farm resources include dairy cattle, a Lidia bovine population called "Brava dos Acores", destined to the typical Azorean street bullfighting "touradas à corda", as well as the traditional equestrian bullfight (in the ring), has an important place in cattle breeding in the Azores and particularly in Terceira Island. These farms are located essentially in the center of the island in areas where the edaphoclimatic conditions are poorer, integrating this livestock farming into the landscape and in the community. The system is characterized by land scarcity and the major livestock feed resources include grazing on marginal lands where animals are raised in special conditions, distinguished by its extensive management. For this reason, farm data-recording systems at the smallholder Lidia cattle level are either totally absent or incomplete, so it is usually difficult to get reliable data with which to evaluate the performance of smallholder cattle. Actually, about 2500 of Lidia animals are registered in the Zootechnical register of the bovine breed "Brava dos Açores" distributed to 42 breeders. From these animals, data related to the reproductive events of 94 females aged more than 24 months and distributed by four herds were followed and a database outlined created for each farm. Data of reproductive parameters included the number of registered cows, mean age of the breeding herd, the number of calving's, the average age at first calving, the apparent fertility rate, and the actual fertility rate, as well as the calving interval.Results demonstrated that considering all animals, the mean age of females of the reproductive herd was 100.08 ± 23 months. As far as the first calving is considered it has been observed than, on average it occurs at 36 ± 8.5 months, ranging from 30-48 months. For the calving interval, on average cows only the gave birth almost every two years (680 ± 75 days). For apparent and real fertility, results were respectively 76.5% and 41%. Results obtained in the present study clearly allows concluding that, falling fertility rates are a big concern for Lidia farmers as these animals are very dependent on the environment, the fact of not there is a large amount of food during the spring and summer, can explain the low fertility observed. Moreover, measures to improve the reproductive performance in females, could pass throughout making sure herd's diet meets the necessary protein, fat, energy and mineral requirements, besides in practice, getting it right is a little trickier. As normally the body condition score of this females are very low, supplementation with protein and energy could solve part of the problems as it is well known that certain fats increase progesterone -a hormone that plays an important role in facilitating healthy pregnancies.
