Ojective. genetical characterization the creole Colombian sheep and their relationships with breeds of European origins. Materials and methods. Blood samples of 261 sheeps from the following populations were collected: Criollos de Lana (CL), Mora Colombiana (MC), Criollo de Pelo (CP), criollos mestizos (Mes), Hampshire (Hamp), Corriedale (Corr), Katahdin (Kath), Pelibuey (Pel), in 40 farms of 8 departments (Cordoba, Magdalena, Cesar, Atlantico, Valle del Cauca, Narino, Boyaca, Tolima) and 30 samples of Merino Spanish, Merino Precoz (MP), Merinofleischschaf (MF), Segureno (Seg) and Uda (UD) de Nigeria. A total of 15 microsatellites markers were included inthis study. Results. In creole sheep, the average number of alleles was found 6.20±1.48 (CL), 7.27±1.39 (CP) y 3.60±1.55 (MC); high genetic diversity found (high heterozygosities 75%), negative values in the FIS revealed high degree of introgression; furthermore the FST revealed genetic structure in both: Creole sheep (FST=0.02**) and departments (FST=0.039**).According to genetic distance, the creole Colombian sheep differs with outsider sheep. Conclusions. The results recommend protecting the Creole sheep production because it has been threatened by constant cross with foreign breeds, which would lead to the loss of genetic identity and adapting traits of creole sheep.themselves.
Ojective。哥伦比亚克里奥尔羊的遗传特征及其与欧洲起源品种的关系。材料和方法。在8个省(科尔多瓦、马格达莱纳、塞萨尔、Atlantico、cauka山谷、Narino、Boyaca、Tolima)的40个农场采集了以下种群261只羊的血样:Criollos de Lana (CL)、Mora Colombiana (MC)、Criollo de Pelo (CP)、Criollos mestizos (Mes)、Hampshire (Hamp)、Corriedale (Corr)、Katahdin (Kath)、Pelibuey (Pel)，以及30只西班牙美利奴、美利奴Precoz (MP)、Merinofleischschaf (MF)、Segureno (Seg)和Uda (UD) de Nigeria。本研究共纳入15个微卫星标记。结果。克里奥尔羊平均等位基因数分别为6.20±1.48 (CL)、7.27±1.39 (CP)和3.60±1.55 (MC);遗传多样性高(杂合度高75%)，FIS值为负值表明遗传渗入程度高;此外，FST还揭示了克里奥尔羊(FST=0.02**)和科(FST=0.039**)的遗传结构。根据遗传距离，克里奥尔哥伦比亚羊与外来羊不同。结论。研究结果建议保护克里奥尔羊的生产，因为它一直受到与外国品种杂交的威胁，这将导致克里奥尔羊自身遗传特性和适应性特征的丧失。

Objective. To describe the prevalence of canine mammary gland tumors (CMT) in females in the municipality of Manizales-Colombia from 2014-2017. Materials and methods. A database of 15961 patients was consolidated. The variables analyzed were, breed, age, reproductive history, weight, diet type and clinical characterization of the tumor with the TNM (tumor-node-metastases) staging system. The statistical analysis include Pearson’s chi-squared test with Yates correction for continuity and Fisher’s exact test (p<0.05), relative risk and odds ratio (CI95%) and Kaplan-Meier estimator for survival analysis. Results. The incidence in purebred dogs was 79.14%, with a peak at the average age of 9.3 years old. Pearson’s chi-squared test and the relative risk and odds ratios indicated a high risk for purebreds (p=0.019, 3.96/100, 1.64, respectively). Females of ages between 9 and 12 years old showed a 74% likelihood of developing a mammary tumor. No found significant relation to weight or reproductive stage but indeed a high association with homemade diet (p<0.001). The inguinal mammary pairs were the most affected (6.9%). The Kaplan-Meier estimate showed a higher survival of surgically-intervened patients, with 2013 days of survival after diagnosis with surgery compared to 1484 days without surgery. Conclusions. The study confirmed the relevance of risk factors, breed type, age, body condition and diet type in the mammary tumor presentation. Furthermore, it highlights the need for improving and integrating the veterinary diagnostic information systems, considering their importance in public health.

Dogs with Giardia infections have diarrhea that persists for days, even after treatment. We managed canine giardiasis using two distinct approaches: treatment with the antiprotozoan secnidazole alone; and secnidazole plus a homeopathic product that is indicated for control of diarrhea in dogs. Treatment I: Ten beagle dogs showed clinical signs of severe diarrhea. Their feces revealed large numbers of cysts consistent with Giardia sp. Therefore, we treated the dogs with secnidazole (10 mg/kg, single dose) given orally. Five days after treatment, all dogs were negative for Giardia spp. Treatment II: Three months later, the same ten Beagles again presented with diarrhea. Feces were collected, revealing Giardia sp. in all dogs. This time, we treated them with an antiprotozoan (secnidazole, 10 mg/kg dose) combined with a commercial homeopathic drug for diarrhea control (3 g dose/animal at 12 h interval). We found that three to five homeopathic doses were needed to achieve normal fecal scores in all dogs. After 5 days of treatment, stool samples had normal consistency and were negative for Giardia. This is the first record of using secnidazole to control canine giardiasis associated with homeopathic drugs to prevent diarrhea.

Anamnesis: paciente canino, maltés, femenino, castrado, 4 años y 5 Kg. de peso El motivo principal de consulta fue tos y dificultad respiratoria grave. Hallazgos clínicos y de laboratorio: Durante la evaluación clínica, el paciente presentó cianosis, estridor inspiratorio y espiratorio severo, tos en graznido especialmente después de una emoción. Se realizó un examen a través de una broncoscopia, que reveló una disminución dinámica en el diámetro de la luz traqueal, un colapso severo en las porciones cervicales y torácicas. Enfoque de tratamiento: Debido a la gravedad del colapso traqueal, se decidió la implantación de un stent de nitinol. La elección del stent es fundamental; Fue necesario realizar una medición del diámetro y la longitud de la tráquea para minimizar los efectos secundarios y los rechazos. La tráquea presentó variabilidad del diámetro a nivel torácico por esta razón se decidió utilizar un stent dual, el stent se colocó en observación directa utilizando un broncoscopio pediátrico. Conclusión: Presentamos un caso en el que se usó un stent dual, indicado en casos en que el diámetro de la tráquea varía, obteniendo excelentes resultados ya que se ajustó a los diferentes diámetros traqueales que el paciente presentó en los niveles cervical y torácico.

Objective. To quantify the concentration and consumption of the protein fragments (NPN, TP, RDTP, SDTP, NDIP, and ADIP) present in the diet supplied to cattle, and its effect on the digestibility of crude protein. Materials and methods. Diets offered to Chino Santandereano cattle in stables were analyzed, receiving different levels of supplementation, using four animals in the 4x4 Latin square outline, the treatments being: NS, not supplemented; LOW, supplemented with an amount relative to 0.5% of body weight; MEDIUM, supplemented with an amount relative to 1.0% of body weight; HIGH, supplemented with a quantity relative to 1.5% of body weight. Consumption was determined daily, and digestibility through total stool collection in the last two days of each period. Results. A higher concentration of crude protein was found in supplement compared to grass (p<0.001), the forage exhibiting a higher concentration of CPNPN (p<0.001), at the same time, that the supplement presented higher concentration of TP (p<0.001) and RDTP (p=0.027). Supplemented animals presented higher consumption of CP, CPNPN (p=0.037), TP, NDIP, RDTP, ADIP and SDTP (p<0.05), however, when the concentration that represents the consumption of ADIP in the consumption of CP was determined, no difference was observed between supplemented and NS (p=0.078). Higher digestibility of CP was found in supplemented animals when contrasted with NS (p<0.001), an upward linear effect was observed between supplemented treatments as the level of supplementation increased. Conclusions. Supplementation improves the digestibility of crude protein by providing a greater amount of highly digestible nitrogenous fragments.

Objective. To determine Mycobacterium avium subsp. paratuberculosis (MAP) molecular diversity in environmental samples from Colombian dairy herds. Materials and methods. Environmental samples from 25 IS900-qPCR MAP-positive dairy herds were cultured by duplicate in Herrold ́s egg yolk medium with mycobactin J to obtain isolates. Suspicious colonies were confirmed by MAPIS900-qPCR. Positive DNA was sub-typed using mycobacterial interspersed repetitive units-variable number of tandem repeat (MIRU-VNTR) and multilocus short sequence repeats (MLSSR) techniques to analyze the genetic differences between the isolates. Results. Sub-typing revealed two different genotypes by MIRU-VNTR (INMV 2 and INMV 36). MLSSR technique was carried out to increase the
