An online questionnaire was emailed to 110 small animal veterinarians who attended the course between 2007 and 2017. The questionnaire comprised three sections: general attendee information, questions pertaining to the received laparoscopic and thoracoscopic training, and finally enquiries on cumulative post-training and current MIS practice. Forty-five veterinarians answered the questionnaire. Most respondents had prior laparoscopy and/or thoracoscopy experience (95.2 %), but close to half (46.7 %), modified their clinical practice as a result of the training. Seventy-five percent of the totally inexperienced participants started practicing MIS within two years of attending the course. A large proportion of respondents indicated their need for additional training for more advanced laparoscopy (71.1%) and thoracoscopy (77.8%) procedures. Accordingly, the main difficulty found by respondents regarding MIS implementation was insufficient training (37.8%). The most frequently encountered difficulty during procedures was bleeding (46.7%), while the most feared complication was related to anesthesia (31.1%). Ovariectomy and ovariohysterectomy were the most frequently performed minimally invasive procedures in trainee working centers. MIS training promotes the introduction of laparoscopy and thoracoscopy into clinical practice and expands the type of surgeries performed with these approaches. Nonetheless, a single intensive program does not comply with the diverse training needs of small animal practitioners.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46426293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The anesthetic protocol began with a simultaneous intrapectoral injection (IP) of MED (50 μg/kg) and MID (0.5 mg/kg), followed by IP administration of 25 mg/kg of KET 10 min later. Anesthesia was then maintained for 30 min by 2% SEVO (with a 500 ml/min oxygen flow), using an Ayres T piece device. Heart and respiratory rates, cloacal temperature, reflex response and electrocardiogram (ECG) parameters were recorded at time cero (T0) before anesthesia (BA, baseline values), at time of MED+MID administration (T1), at time of ketamine injection (T2), 30 min after the start of SEVO inhalation (T3) and at recovery. Blood was also drawn at T0 and T3 to assess albumin, creatinine, glucose and liver enzyme concentrations. Cloacal temperature, heart and respiratory rates differed from baseline values at all time intervals during anesthesia (p<0.05). Heart rate decreased following the MED + MID injection (at T1, T2 and T3), and partially recovered by the reanimation period. Reflex response also differed between time 0 and all anesthesia time points (p<0.05). Mean amplitude of the P wave of the ECG was increased during MED + MID (T1) and KET (T2) anesthesia. The mean ST interval showed a large increase at T1, which was maintained throughout anesthesia (p <0.05). Albumin, glucose and the ALT enzyme decreased between T0 and T3. In conclusion, the use of MED+MID+KET and SEVO as an anesthetic combination altered cardiorespiratory and biochemical parameters of chickens, but no life-threatening effects were observed as a result of these changes. Hence, this drug combination can be adequately used as an anesthesia protocol in chickens.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.22201/fmvz.24486760e.2020.1.620","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46148189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five extract concentrations were assessed in the inhibition tests (25.0, 12.5, 6.2, 3.1 and 1.5 mg/mL), using distilled water and Thiabendazole (0.5 mg/mL) as negative and positive controls, respectively. The results were analysed under a 2 × 2 × 6 completely randomized factorial design, and mean differences were established by the Tukey’s post hoc test. The 50% (EC50) and 90% (EC90) effective concentrations for each extract were determined using a Probit analysis.A concentration-dependent ovicidal effect of hydro-alcoholic extracts from both leaves and fruits was observed, reaching a 100% efficacy against both nematode species with the 25.0 mg/mL concentration (p < 0.05). The EC50 for the fruit and leaves extracts were established as 1.63 and 3.91 mg/mL, and as 3.98 and 11.68 mg/mL, against H. contortus and H. placei, respectively.

Diets were provided ad libitum in a mash form, from days 8 to 21 of age. In Experiment 1, one day old male broiler chicks (n=210) were assigned to one of 7 treatments, with 3 replicates of 10 birds each. Animals in treatment 1 (T1) were fed a basal diet formulated to be deficient in nonphytate P (0.14%). Birds in T2 and T3 received the basal diet supplemented with 0.05% or 0.10% of P from monodicalcium phosphate (MCP), respectively. Phosphorus from DDGS was added to diets in T4 (0.05% from DDGS A), T5 (0.1% from DDGS A), T6 (0.05% from DDGS B) and T7 (0.1% from DDGS B). Percent of inclusion of DDGS was dictated by total P content as determined by chemical analyses. Growth performance and P intake were assessed in all birds. Phosphorus bioavailability was determined using the slope ratio assay, with tibia ash as the response variable. For Experiment 2, one-day-old male broiler chicks (n=200), were assigned to 5 treatments with 4 replicates of 10 birds each. A sorghum-soya control diet was given to animals in T1. Treatments 2 and 3 included this same diet supplemented with either 5% or 10% of DDGS A. Birds in T4 and 5 received the control diet with either- 5% or 10% of DDGS B. Amino acid digestibility was measured from ileal contents in 7 euthanized birds from each group at day 21. Apparent metabolizable energy was determined in oven dried feces from all animals during the last 3 days of the experiment.  Weight gain and feed consumption increased (P <0.001) with larger inclusion of dietary P in birds from experiment 1. Relative P bioavailability for DDGS A and B was 72% and 86% respectively, from a P total content of 0.85% and 0.94%.,. Growth performance was similar for all treatment groups in experiment 2 (P >0.05). The average apparent ileal amino acid digestibility coefficient for DDGS A 76.5% and B was 76.4%.

Su notificación debe ser inmediata y obligatoria. A pesar del nombre que se le ha dado, el caballo es sólo un huésped incidental. La manifestación clínica de las tres encefalitis es muy similar, por lo que se requiere de una correcta toma y envío de muestras al laboratorio para lograr un diagnóstico diferencial. Los ciclos de infección se presentan de dos formas: enzoótica, en la que el virus permanece por largos períodos circulando entre los huéspedes reservorios y el vector transmisor; y epizoótica, que involucra a los huéspedes incidentales y a los vectores transmisores. Los principales signos en caballos son alteración del comportamiento, dificultad visual, deambulación, caminata en círculos, dificultad en la deglución, ataxia, paresia, parálisis y convulsiones. No existe tratamiento, por lo que su manejo se enfoca a la terapia de soporte, con un pronóstico desfavorable, ya que la tasa de mortalidad (dependiendo de la encefalitis de la que se trate) puede llegar al 90%. La EEV es endémica en México y es la que presenta más riesgo, ya que, a diferencia de las otras dos, los caballos afectados suelen desarrollar viremia, por lo que pueden transmitir la enfermedad a través del piquete de mosco a otros huéspedes animales o al ser humano. En cuanto a las EEE y EEO aún no se han reconocido oficialmente en el territorio mexicano. Sin embargo, en marzo del presente año, se detectaron 44 casos de EEO en equinos en Nayarit.

Over 50% of farmers have an activity other than cattle breeding, mostly raising crops and other livestock. Weaned calves, primarily destined for the national market, are the foremost commercial product. Nevertheless, 20% of farmers in the northern region export their calves. European X Zebu crossbred cattle are widespread (over 45% of operations), followed by Bos taurus taurus breeds (22%). Criollo and predominantly Zebu cattle are present in <15% of farms, and dairy breeds in <5%.
