Abstract:
SUMMARYItalian autochthonous goats have been discriminated for centuries, first by laws which have limited their rearing, then because foreign breeds, such as Saanen and Alpine, were preferred. Recently, this trend changed and now the number of autochthonous goats is increasing. In Italy, the only goat which can be considered as being wild is the Capra di Montecristo. Among domesticated goats, the Vallese is classified as Capra prisca; the Maltese, the Rossa Mediterranea, the Garganica, the Orobica, the Frontalasca, the Verzaschese, the Sarda, the Argentata dell'Etna and the Locale are classified as Capra hircus hircus while the Girgentana is classified as Capra hircus girgentana.Data have been published on the production and reproduction of each of these breeds, on the importance of the populations and on development trends; many reports exist on the rearing areas of these breeds.

Abstract:
We assessed polymorphisms in exon IV of the κ-casein gene (CSN3) in ten different breeds of domestic goat (Capra hircus) from three continents and in three related wild caprine taxa (Capra <ibex> ibex, Capra <ibex> sibirica and Capra aegagrus). Thirty-five DNA samples were sequenced within a 558 bp fragment of exon IV. Nine polymorphic sites were identified in domestic goat, including four new polymorphisms. In addition to four previously described polymorphic positions, a total of 13 polymorphisms allowed the identification of 13 DNA variants, corresponding to 10 protein variants. Because of conflicting nomenclature of these variants, we propose a standardized allele designation. CSN3*A, CSN3*B, and CSN3*D were found as widely distributed alleles in European goat breeds. Within Capra ibex we identified three variants and showed that the sequence of Capra aegagrus is identical to the most common Capra hircus variant, consistent with Capra aegagrus being the wild progenitor of domestic goats. A dendrogram was drawn to represent the molecular network between the caprine CSN3 variants.

Abstract: This study provides the first characterization of maternal ancestry and mitochondrial DNA (mtDNA) diversity in the Croatian Spotted goat (CSG), the most important autochthonous goat breed in Croatia. CSG (n = 25) were randomly sampled from seven herds and a 660-bp fragment from the mtDNA D-loop region was sequenced. Those sequences were compared with 122 corresponding GenBank sequences from goat populations in Albania, Austria, Egypt, Greece, Italy, Romania and Switzerland. CSG showed a great polymorphism (only three out of 17 haplotypes were shared) with high a haplotype (Hd = 0.967 ± 0.019) and nucleotide diversity (π = 0.01305 ± 0.00068). When compared with Mediterranean and ancient goats, all of the 25 CSG were randomly scattered inside haplogroup A showing the weak phylogeographic structure with within-breed variance accounting for 91.76% of the genetic variation. In addition, population expansion tests (mismatch distribution and Fu’s Fs statistic) supported these results suggesting at least one population expansion.

Abstract:
(1) Reliable measures of population abundance are essential for managing wildlife effectively. Aerial surveys provide a rapid and efficient means of surveying large mammals and many techniques have been developed to adjust for the inability to count all animals within transects. The probability of detection varies according to a range of factors which are important to consider when estimating density. Standardised survey methods developed in flat country are not readily transferable to steep terrain due to safety, access and difficulties delineating transect widths. Other methods have logistic constraints and must adhere to various other assumptions. (2) Density estimators are seldom examined using actual population size, hence their ability to correct for true bias is unknown. Studies that compare techniques are difficult to interpret because of the uncertainty of adherence to their respective assumptions. Factors influencing detection probability, estimators that correct for bias, the validity of their assumptions and how these relate to true density are important considerations for selecting suitable methods. The aim of this study was to obtain accurate and reliable methods for estimating the density of feral goats by improving predictions of detection probability, investigating the assumptions of aerial surveys, and examining the accuracy of 15 density estimators by comparing with total counts of feral goats. (3) Group size, vegetation and observer were the most important factors influencing the probability of observing a group of goats during aerial surveys. However, different approaches to analysing these data influenced the significance of variables and the predicted probabilities. Goat colour, type of helicopter, site and rear observer experience in hours were also found to be significant (P<0.05) when using likelihood equations based on all animals in the population rather than only those in the sample. The slope of the terrain was also shown to significantly (P=0.014) affect the probability of detection. (4) Indices are commonly used in wildlife management for their simplicity and practicality, but their validity has been questioned because of variable probability of detection. Results of this study suggest aerial survey indices are useful in monitoring a range of medium-sized mammal species across space and time if differences in detection probability between species, group size, vegetation and observer are considered and their effects are standardised. (5) An assumption of most sampling regimes that is fundamental but rarely examined is that animals are not counted more than once. In this study the behavioural responses of feral goats to helicopters were investigated as a basis for estimating the probability that goats were recounted. No long-term consequences were evident in feral goat behaviour of responses to helicopters. However, helicopter surveys were found to alter the structure of 42% of groups observed, with 28% of groups merging with others and 14% splitting into separate groups. Therefore, group size estimated from the air should not be considered as biologically important, and when estimating density, researchers should also avoid using group sizes determined from independent ground observations to correct group sizes determined from aerial surveys. Goats were also more likely to flush further when helicopters were within 150 m, which is close to or within standard helicopter strip widths. Substantial movement occurred between transects and 21% of goats were estimated to be available for recounting in adjacent transects. (6) Different detection probabilities between groups of goats may be particularly relevant when using double-counting, where multiple observers are �capturing� and �recapturing� animals in the same instant. Many analyses test and adjust for this �unequal catchability� assumption in different ways, with the approaches of Huggins and Alho allowing prediction of unique probability values for a range of co-variates. The approach of Chao attempts to correct for skewed distributions in small samples. The Horvitz-Thompson approach provides a useful basis for estimating abundance (or density) when detection probability can be estimated and is known to vary between observations according to a range of independent variables, and also avoids errors associated with averaging group size. (7) After correcting for recounting, the Alho estimator applied to helicopter surveys was the most accurate (Bias = 0.02) and reliable of all techniques, which suggests that estimates were improved by taking into account unconditional detection probability and correcting individual observations according to their characteristics. The positive bias evident in the Chao (Bias = 0.28) and Petersen (Bias = 0.15) aerial survey estimators may have been a result of averaging detection probability across all observations. The inconsistency and inaccuracy of the ground-based area-count technique emphasises the importance of other assumptions in density estimation, such as representative sampling and availability bias. The accuracy of index-manipulation-index techniques was dependent on the indices used. Capture-recapture estimates using mustering showed slight negative bias (Bias = -0.08), which was likely a result of increased probability of re-capture (i.e. trap happy). Ground-based capture-resight estimates were labour intensive and positively biased (Bias = 0.13), likely due to underestimating the area sampled, or overestimating the number of unmarked individuals with each sample. (8) Helicopter survey using double-counting is recommended for estimating the density of feral goats in steep terrain. However, consideration of recounting under intensive sampling regimes and adjustments for the factors that influence unconditional detection probability is required.

Abstract:
Visando melhoria das técnicas de colheita embrionária por via transcervical em caprinos, o presente experimento testou a viabilidade da utilização da sonda uretral humana nessa espécie animal. Utilizou-se 18 animais da raça Boer puros de origem como doadores de embriões que, após serem superovulados foram tranqüilizados e colocados em uma mesa específica para colheita com o animal em estação. Com auxílio de um espéculo vaginal, a sonda foi introduzida via transcervical no interior do corpo uterino e procedeu-se as lavagens com solução fosfatada (PBS). Após as lavagens o conteúdo foi filtrado e os embriões avaliados e selecionados. Os percentuais relativos à viabilidade da passagem da cérvice, embriões coletados e volume de líquido coletado foram de 83,3%, 81,15% e 94,3% respectivamente. Viabilizando a técnica adotada, em função das dificuldades de se ultrapassar a cérvice em fêmeas primíparas, recomenda-se a adoção de outras técnicas

A caprinocultura é considerada um segmento de grande importância em agronegócios no país, gerando importante fonte de carne e leite, principalmente na região Nordeste. Entretanto, este criatório sofre grandes perdas econômicas devido às parasitoses que acometem o trato digestório. Dentre estas, destaca-se, o gênero Haemonchus, cujas espécies H. contortus e H. placei parasitam abomaso de caprinos e bovinos, respectivamente, havendo possibilidade de infecção cruzada dessas duas espécies helmínticas. O objetivo do presente estudo foi avaliar a viabilidade do parasitismo por H. placei em caprinos e compará-la à patogenicidade por H. contortus. Foram utilizados 14 caprinos, recém-nascidos, mantidos em gaiolas metálicas de piso suspenso, assim distribuídos: GI - quatro cabritos inoculados com 5000 larvas infectantes (L3) de H. placei, GII – quatro infectados com 5000 larvas infectantes (L3) de H. contortus, GIII – quatro animais inoculados com 2500 larvas L3 de H. contortus + 2500 H. placei e GIV – dois cabritos que receberam apenas água (controle). Exames de contagem de ovos de estrongilídeos por grama de fezes (OPG) foram realizados diariamente, após o 7º dia da inoculação. Os períodos pré-patentes foram de 24 dias para H contortus e de 31 dias para H. placei. O grupo inoculado apenas com H. placei apresentou médias de OPG inferiores quando comparado aos demais grupos. Decorridos 42 dias pós-infecção, os 14 caprinos foram eutanasiados e necropsiados, sendo coletados “in totum” os exemplares de Haemonchus. O grupo I apresentou média de 25,5 espécimes H. placei, o grupo II média de 619,5 de exemplares de H. contortus, o grupo III média de 120 exemplares de H. placei e 604,75 de H. contortus e no grupo IV nenhum helminto foi diagnosticado. Não foram constatadas quaisquer outras espécies e nem formas imaturas de Haemonchus no trato gastrintestinais dos caprinos. Fragmentos do abomaso foram coletados e armazenados em formol tamponado para análise histopatológica. Foram observados no grupo I lesões microscópicas leves apenas com poucos focos inflamatórios. Nos grupos II e III foram diagnosticadas lesões extensas, como edemas, focos inflamatórios difusos, infiltrado de eosinófilos, diminuição das células parietais. No grupo IV nenhuma alteração histopatológica foi diagnosticada. Nas condições desse estudo, a espécie caprina foi razoavelmente susceptível ao parasitismo por Haemonchus placei, sendo esse parasitismo mais proeminente nos animais que receberam infecção mista (H. placei + H. contortus).
Goat breeding is considered a very important segment in Brazilian agribusiness, generating a significant source of meat and milk. However, this industry suffers great economic losses due to parasitic diseases that affect the digestive tract, compromising their development. Among these, the Haemonchus genus stands out, with H. contortus and H. placei parasitizing goats and cattle, respectively, with the possiblity of cross infection between these helminth species in abomasu of hosts. The objective of the present study was to estimate the viability of H. placei parasitism in goats, and compare it with H. contortus pathogenicity. Fourteen newborn goats were used, distributed in the following way: GI - four goats inoculated with infective larvae (L3) of H. placei; GII – four animals infected with infective larvae (L3) of H. contortus; GIII - four caprines inoculated with larvae L3 of H. contortus + H. placei; and GIV - two goats that received only water (control). Each animal received 5000 L3 of Haemonchus species, in a single dose, orally. Egg per Gram of Feces (EPG) exams were performed daily after the 7th day of inoculation, establishing that the pre-patent period of H. contortus was 24 days and H. placei was 31 days. The group inoculated only with H. placei presented lower EPG means when compared to the other groups. After 42 days post-infection, all 14 goats were euthanized and necropsied, and Haemonchus specimens were collected “in totum". Group I presented an average of 25.5 specimens, while the mean of group II was 619.5, group III obtained an average of 120 specimens of H. placei and 604.75 of H. contortus and group IV did not present any specimens. No other species and no immature forms of Haemonchus were found in gastrintestinal tracts of experimental animals. Fragments of abomasum were collected and stored in buffered formalin for histopathological analysis, in which GI group showed mild microscopic lesions with only a few inflammatory foci, while groups II and III had extensive lesions, such as edema, diffuse inflammatory foci, eosinophilic infiltrate and hyperplasia of parietal cells. Group IV showed no changes. Under conditions of this study, the caprine species did not present itself as susceptible to parasitism by Haemonchus placei, with such parasitism being more prominent when in consortium with Haemonchus contortus.

After T. gondii inoculation, 12 nonpregnant female breeder goats serologically negative for the main reproductive diseases, especially toxoplasmosis, were synchronized and then exposed to natural mating by those males previously inoculated, being: five females submitted to natural mating by the male A (GI), five females exposed to natural mating by the male B (GII) and two females submitted to natural mating by the uninfected male (GIII). In sera obtained from all female goats on days -14, -7, -1, (before natural mating) and on days 3, 6, 9, 11, 14 and weekly until partum, the presence of antibodies against T. gondii was investigated by ELISA test. Bioassay in mice and PCR were performed on samples of semen and tissues of males and females and on their products which were stillbirths, fetus and offspring. Ten out of 12 females used showed specific antibodies against T. gondii after natural mating, being five from group GI and five from group GII. On several dates in which natural mating occurred, T. gondii was identified in semen samples of infected males by bioassay and PCR. Subsequently, after euthanasia, it was possible to isolate T. gondii in some of tissue samples from experimentally infected males. Moreover, by PCR and bioassay techniques it was also possible to identify T. gondii in tissue samples from experimentally infected females as well as their products (stillbirths, fetus and offspring). It was not possible to notice any clinical signs of toxoplasmosis Therefore, these results proved, for the first time, the sexual transmission of toxoplasmosis in goat species

Bioassay in mice and PCR were performed on samples of semen and tissues of males and females and on their products which were stillbirths, fetus and offspring. Ten out of 12 females used showed specific antibodies against T. gondii after natural mating, being five from group GI and five from group GII. On several dates in which natural mating occurred, T. gondii was identified in semen samples of infected males by bioassay and PCR. Subsequently, after euthanasia, it was possible to isolate T. gondii in some of tissue samples from experimentally infected males. Moreover, by PCR and bioassay techniques it was also possible to identify T. gondii in tissue samples from experimentally infected females as well as their products (stillbirths, fetus and offspring). It was not possible to notice any clinical signs of toxoplasmosis Therefore, these results proved, for the first time, the sexual transmission of toxoplasmosis in goat species

Abstract:
The physiological effects of etorphine, and etorphine combined with xylazine and etorphine combined with azaperone on respiratory and cardiovascular function were determined in. Boer goats. The goats were habituated to the experimental procedures allowing the determination of respiratory and cardiovascular function while the animals stood quietly at rest. This resulted in the physiological changes induced by the three immobilizing drugs being measured and compared with those obtained prior to the administration of the immobilizing drugs. The: effectiveness of diprenorphine and atipamezole in antagonising the physiological changes induced by the immobilizing drug treatments was also determined. All three immobilizing drug treatments depressed respiratory function resulting in a decrease in PaO2and an increase in PaCO2. Etorphine caused limited changes to these blood gases as a result of decreases in respiratory minute volume and alveolar minute ventilation caused by a fall in respiratory rate. The administration of etorphine / azaperone did not decrease the efficiency of respiration more significantly than when etorphine was administered on its own. Etorphine injected in combination with xylazine resulted in a severe decrease in respiratory function. The decrease in PaO2 and the increase in PaCO2 were much greater than the changes to these two blood gases following the administration of either etorphine or etorphine in combination with azaperone. Compared to etorphine administered on its own, etorphine combined with xylazine caused more significant decreases in tidal volume and alveolar minute ventilation, and more significant elevations in both physiological shunt fraction and percentage dead space ventilation. The administration of etorphine, etorphine / xylazine and etorphine / azaperone caused three different sets of changes to cardiovascular function. The injection of etorphine resulted in significant increases in both total peripheral resistance and systemic mean arterial blood pressure, and a significant decease in cardiac output. The administration of etorphine / xylazine resulted in a rapid and significant decrease in the systemic mean arterial blood pressure, followed by a decrease in cardiac output. The peripheral resistance remained unchanged. Etorphine / azaperone caused a progressive decline in the total peripheral resistance. As the cardiac output did not change significantly, the systemic mean arterial blood pressure fell progressively. The administration of etorphine resulted in a gradual and limited decrease in the oxygen consumption index. Following the injection of etorphine / xylazine a rapid and significant decrease in the oxygen consumption index resulted, which was significantly lower, when compared to the goats immobilized with etorphine, at 5 and 35 minutes PDA. The injection of etorphine / azaperone resulted in a gradual decrease in the oxygen consumption index which reached a minimum value at 35 minutes PDA. At this time, the oxygen consumption index due to etorphine / xylazine was not significantly different from the value due to etorphine / azaperone. Diprenorphine effectively reversed the respiratory and cardiovascular effects due to etorphine. The physiological changes induced by the administration of etorphine / xylazine were partially and temporarily antagonised by the administration of diprenorphine, it was only following the injection of atipamezole that they return to the values measured in the goats prior to immobilization. Diprenorphine effectively reversed the respiratory depression induced by etorphine / azaperone, however a mild acidosis persisted until the end of the trial period. The cardiac output and systemic mean blood pressure improved dramatically following the injection of diprenorphine but there was no immediate change in total peripheral resistance.

Abstract:
O crescimento da caprinocultura no Brasil e a necessidade de controle sanitário dessas criações justificam o estudo de avaliação do teste tuberculinico na espécie caprina. Utilizando os parâmetros de Silva et al. (2006) foram avaliados 600 caprinos procedentes dos Estados de Minas Gerais, Paraná, Pernambuco, Paraíba e São Paulo. Baseados nos valores do Teste Cervical Comparativo (TCC) 60 animais foram selecionados e submetidos a exame clínico, eutanásia e colheita de material para exames microbiológicos, histopatológicos e moleculares. Dos 36 caprinos positivos, 27 (72%) resultaram em isolamento de micobactérias tipificadas como sendo do complexo M. tuberculosis. Foram identificados focos de tuberculose em caprinos nos Estados de São Paulo, Minas Gerais e Paraíba. Além do isolamento de micobactérias do complexo M. tuberculosis, foram identificados em alguns animais outras bactérias como M. kansasii, M. flavescens, M. avium, complexo M. florentinum M. lentiflavum M. simiae, Corynebacterium pseudotuberculosis e C. bovis. Em um caso houve o isolamento de C. bovis concomitante com micobactéria do complexo M. tuberculosis. As lesões macroscópicas e histopatológicas não diferenciaram a infecção provocada por C. bovis. ou por micobactéria do complexo M. tuberculosis. Os resultados bacteriológicos, histopatológicos e de identificação genética validam a utilização do padrão de interpretação de Silva et al. (2006) no TCC para o diagnóstico da tuberculose em caprinos.
The development of farming goats in Brazil, and the need of sanitary control of these flocks, justify the study of tuberculin test evaluation in goats. Using cut-off points established by Silva et al. (2006), 600 goats from Minas Gerais, Paraná, Pernambuco, Paraíba and São Paulo states were evaluated. According to Comparative Cervical Test values, 60 goats were selected, and submitted to clinical exams, euthanized and materials collected for microbiologycal, histopathologycal and genetic typing. Out of the 36 positive goats, 27 (72%) had isolation of micobacteria classified like Mycobaterium tuberculosis complex. Focus of tuberculosis were identified in São Paulo, Minas Gerais and Paraíba states. Besides isolation of the M. tuberculosis complex micobacteria, other bacterias like M. kansasii, M. flavescens, M. avium, M. florentinum lentiflavum simiae complex, Corynebacterium pseudotuberculosis and C. bovis were identified in some animals. In one case, isolation of C. bovis occurred together with micobacteria of the M. tuberculosis complex. The macroscopic and histopathological lesions did not discriminate infection for C. bovis or of the M. tuberculosis complex micobateria. The bacteriological, histopathological and genetic typing results validate the use of cut-off points established by Silva et al. (2006), in the Cervical Comparative Test for diagnosis of tuberculosis in goats.

Abstract:
Sites of the Neolithic Jeitun Culture in southern Turkmenistan present the earliest evidence of animal husbandry, mainly based on sheep (Ovis aries) and goats (Capra hircus), in Central Asia. In its northern parts, subsistence economy relied on the exploitation of wild animal resources in the Neolithic and Chalcolithic. The steppes of north Kazakhstan played a prominent role in the domestication of the horse (Equus caballus) some time prior to 3000 bc. In subsequent periods, horse breeding was of great economic importance in this area. In the Bronze Age, the Bactrian camel (Camelus bactrianus) became a common livestock animal in the Eurasian dry zones. Its domestication seems to have taken place in the southwestern part of Central Asia. According to geography, vegetation, and climate, different types of animal keeping and herd management developed in the centuries of the Bronze and Iron Ages.

Abstract:
Mitochondrial DNA is an important tool for human identification and is used to differentiate between human and animal blood at the crime scene, because in extreme conditions nuclear DNA is severely destroyed while Mitochondrial DNA contains multiple copies (200–2000) per cell and resists harsh and more stable conditions. Seventy-two blood samples were collected from humans (Homo sapiens), sheep (Ovis aries), goats (Capra hircus), and cows (Bos taurus) (18 blood samples for each). All blood samples were withdrawn by a technician and 5 ml were aspirated using an aseptic technique and transferred to EDTA-Na2 tubes. They were mixed well and stored in a refrigerator. The collection took 2 weeks (May 15, 2019–May 30, 2019). All samples were collected from Al-Diwanyia city. The results of PCR testing revealed that the primer pairs were specific and non-specific products did not appear for all samples. The amplification of Homo sapiens mitochondrial DNA with primer pairs of other (Ovis aries, Capra hircus, and Bos taurus) and amplification of each with primer pairs of another genus gave negative results, and this is primary evidence for primer pair specificity. The amplicon of 16S rRNA gene of Homo sapiens was 1200 bp, Ovis aries was 1060 bp, Capra hircus was 820 bp, and Bos taurus was 1300 bp. The sequencing revealed that no cross-reactivity of designed primer pairs and the PCR assay based on the designed primer pairs will be simple, fast, sensitive, specific, and cost-effective. There is sensitivity, specificity, and accuracy in the designed species-specific primer pairs and applicability of the designed primer pairs in forensics to investigate blood spots or evidence belonging for human, sheep, goat, and cow.
