In the veterinary clinic, contraceptive surgery is the most commonly performed surgery in female cats. However, it is not established which surgical technique is the most appropriate. In order to reduce postoperative pain, recovery time, surgery time and technical ease for the surgeon, different surgical techniques and variations of these techniques have been described. This has created the dilemma of performing ovariohysterectomy versus oophorectomy; type of approach: midline, lateral or laparoscopic; and method of ovarian pedicle ligation: harmonic scalpel, plastic and titanium clips, bipolar electrosurgical unit, pedicle knot and traditional ligation. With this in mind, with the objective of establishing which is the most adequate contraceptive surgery in female cats and supported by evidence-based medicine, a systematic review was carried out. Using Google Scholar, Web of Science, PubMed and SciELO search engines, with the following variables to be evaluated: pain, time and technical difficulty. It was found that there is little evidence to establish the superiority of any surgical technique over another and that the choice of surgical technique should be made based on the patient, the surgeon's skills and the availability of materials.
在兽医诊所，避孕手术是对母猫进行的最常见的手术。然而，目前还没有确定哪种手术技术是最合适的。为了减少术后疼痛、恢复时间、手术时间和外科医生的技术便利性，不同的手术技术和这些技术的变化已经被描述。这就造成了进行卵巢子宫切除术还是卵巢切除术的困境;入路类型:中线、外侧或腹腔镜;卵巢蒂结扎方法:谐波刀、塑料钛夹、双极电刀、蒂结、传统结扎。考虑到这一点，在循证医学的支持下，为了确定哪一种是雌性猫最适当的避孕手术，进行了一项系统评价。使用谷歌Scholar, Web of Science, PubMed和SciELO搜索引擎，评估以下变量:疼痛，时间和技术难度。研究发现，几乎没有证据表明任何一种手术技术比另一种手术技术优越，手术技术的选择应根据患者、外科医生的技术和材料的可用性来确定。

Diabetes mellitus is a metabolic disorder with complications such as metabolic syndrome and delayed wound healing. In this experimental study, 36 male Wistar rats were randomly divided into three groups: control, diabetic, and diabetic-extract-treated. Twenty four h after the wound was created in the diabetic group treated with topical B. serrata cream 2.5%, and the rats also received aqueous B. serrata extract (400 mg/kg) by oral gavage daily for 3 weeks. Diabetes was induced in the rats by subcutaneous injection of alloxan monohydrate (120 mg/kg). After anesthesia, the full-thickness of the dorsal skin (25 mm × 25 mm) was removed. On days 4, 7, 14, and 21, and wound specimens were collected to evaluate histopathological wound healing. After the treatments, blood samples were collected to measure biochemical factors. Consumption of B. serrata extracts in the diabetic group significantly decreased glucose, liver enzymes, kidney indicators and lipid profile compared to the diabetic control group (P<0.05). Histopathologic studies showed that the rate of epithelial tissue and collagen fibers formation, as well as wound healing, was higher in the group treated with B. serrata than diabetic groups. Hence, it might be useful in diabetic patients, especially the ones with diabetic wounds.

El oxigeno (O2) y el dioxido de carbono (CO2) son gases vitales para el embrion durante el proceso de incubacion, su nivel es imprescindible en el momento del picaje, con la finalidad de evaluar el efecto del nivel de dioxido de carbono de la incubadora sobre el desarrollo embrionario, los parametros de eclosion y el posterior crecimiento del pollo de engorda, se midio la perdida de humedad, incubabilidad, peso del pollo, tamano del pollo, glucosa sanguinea, hematocrito y proteinas plasmaticas. Un total de 600 huevos de reproductora comercial Cobb 500 de 41 semanas, se seleccionaron por peso de 65 y 70 g, se distribuyeron en dos maquinas incubadoras. Una maquina se mantuvo a 4000 ppm y la otra a 3000 ppm de CO2. Se utilizo un diseno factorial 2 x 2. La incubabilidad fue mayor a 3000 ppm de CO2 y peso de huevo de 65 g; el pollo mas pesado fue con huevo de 70 g, a mayor ppm de CO2 menor perdida de humedad, a menor ppm de CO2 se observo un pollo mas grande, los niveles de glucosa no se afectaron, pero los valores de proteinas plasmaticas fueron menores a 3000 ppm de CO2. Se mejoran los parametros de eclosion al bajar las ppm de CO2 durante el proceso de incubacion.
氧（O2）和二氧化碳（CO2）是孵化过程中对胚胎至关重要的气体，它们的水平在切碎时至关重要，为了评估孵化器的二氧化碳水平对育肥鸡胚胎发育、孵化参数和随后生长的影响，测量了水分损失、孵化率、鸡重、鸡大小、血糖，红细胞压积和血浆蛋白。共有600个41周龄的Cobb 500商业繁殖蛋，按重量分别选择65和70克，分布在两台孵化机中。一台机器保持在4000 ppm，另一台机器保持在3000 ppm二氧化碳。使用了2 x 2阶乘设计。孵化率高于3000ppm二氧化碳和65g蛋重；最重的鸡肉是70克的鸡蛋，较高的二氧化碳含量会降低水分损失，较低的二氧化碳含量会观察到较大的鸡肉，葡萄糖水平不会受到影响，但血浆蛋白值低于3000 ppm二氧化碳。在孵化过程中降低二氧化碳的ppm，提高了孵化参数。

In the present study, the Population structure and genetic diversity of 104 Yucatan black hairless pigs (YBH) and 8 Duroc breeds were BY using an SNP50K chip characterized. The population structure was obtained, as well as the calculation of Principal Component Analysis (PCA), Minor Allele Frequency (MAF), heterozygosity observed (oH), Relationship (F), Fixation index of individuals within subpopulations (Fis), the t (outcrossing rate or allogamia index) was made, also the association analysis to identify SNP with population differences. The genetic component of Duroc in YBH subpopulations is low, from 0.00363 to 0.03532, thus, it was observed (appreciating) a subpopulation with greater genetic diversity and lower values of F and Fis, as well as higher oH and t. SNPs were identified (p<1.213E-50 to p< 6.4E-20), associated with genes and biological processes. Genes EHF, DST, PDE8A, FOXA1 and VCL are related to epithelial cell differentiation, morphogenesis, and development of epithelium. Other 30 SNPs are related to nutrient metabolism, 23 SNPs to nutrient transport, 11 SNPs to Immunity, 10 SNPs to muscle, skeletal and embryonic, and 7 SNPs to synapses and receptors. YBH is distant from Duroc with different population structure and genetic diversity with different genes that involve important biological processes.

The genetic variability of S. aureus strains isolated from some cases of bovine mastitis was determined. 335 cows from 27 stables were sampled in 10 municipalities in the state of Jalisco. S. aureus strains were identified from milk samples of each mammary gland of each cow, which were grown in blood agar and based on the characteristics of the culture, biochemical tests, and finally their molecular confirmation by PCR. The genetic variation in the strains was identified by pulsed- field electrophoresis technique. The images of the gels were analyzed using the Bionumerics® software. 2.26% of clinical mastitis and 40.45% of subclinical mastitis were diagnosed with the California test. A frequency of appearance of S. aureus of 9.8% of the total sampled glands was recorded. A genetic variation of 14.9% was observed. The 32 strains analyzed were grouped into pulsotypes with 95% or more of genetic similarity, resulting in 12 pulsotypes. It is concluded that there is great diversity in the genetic variability of S. aureus strains from different stables in the state of Jalisco and a great genetic similarity of strains within each stable.

The BCG (Bacillus Calmette-Guerin) vaccine for the control of bovine tuberculosis has variable efficacy and the generation and testing of new vaccines is required. For this reason, an exploratory study was carried out to evaluate the genotoxicity of two potential vaccines, recombinant bovine tuberculosis in Holstein Freisan calves with an average age of 9 months, using micronucleated erythrocytes (MNE). Five groups were formed: 1) Saline solution, 2) The vector pVAX1 (Vector without insert), CV), 3) Vaccine Mycobacterium bovis (M. bovis) type 1 (PE11 [VR1]), 4) Vaccine M. bovis type 2 (PPE68 [VR2]), 5) Both vaccines (VR1 + VR2). Five blood samples were taken from each organism: the first one prior to treatment, the second to the fourth sample every 24 hours and the fifth one 90 days after treatment. The samples were analyzed with microscopy and MNE/10,000 erythrocytes were counted. MNE frequencies decreased with age (Kruskall Wallis, 95%). When analyzing the treatments with respect to the control, a lower value of MNE was identified in the VR2 groups and in VR1 + VR2 (P = 0.02). These results appear to have a cytoprotective effect; however, it could be a masked myelosuppressive (cytotoxic) effect, since the frequency of MNE decreases due to myelosuppression. To confirm cytotoxicity, it is to continue the study in younger organisms suggested.

El objetivo de este trabajo fue determinar la microbiota vaginal aerobia de cabras criollas, asi como el perfil de susceptibilidad a quimioterapeuticos. Se tomaron muestras de mucosa vaginal de 51 hembras caprinas sanas en edad reproductiva mediante hisopos esteriles. Las muestras fueron procesadas bajo tecnicas de identificacion bacteriologica estandar. Se obtuvo aislamiento bacteriano en el 41.2% de las muestras. Las bacterias aisladas con mayor frecuencia fueron cocos Gram positivos (GP) (65.6%), los generos principales identificados fueron Staphylococcus spp. (31.2%) y Aerococcus spp. (21.9%). En cuanto a bacterias Gram negativas (GN), los aislamientos correspondieron a Escherichia coli (15.6%). Del perfil de resistencia a antibioticos los aislamientos de Aerococcus y Corynebacterium jeikeium, en proporcion, fueron los mas susceptibles a los antibioticos analizados contra bacterias GP. Los antibioticos con menor perfil de resistencia ante aislamientos GP fueron dicloxacilina, cefotaxima y ampicilina. Los aislamientos de E. coli mostraron ser altamente resistentes a todos los antibioticos probados (95%), siendo ciprofloxacina el antibiotico con menor resistencia (60%). Los hallazgos de este trabajo ponen de manifiesto la importancia de la microbiota vaginal en cabras criollas como agentes ecologicos con potencial patogenico, ademas de demostrar la alta resistencia de estas bacterias a agentes quimioterapeuticos.

En la raza ovina Pelibuey, no esta establecida completamente la dosis de gonadotropina corionica equina (eCG) a emplear en protocolos de sincronizacion de estros. El objetivo del estudio fue analizar el efecto de dos diferentes dosis de eCG, incluidas en protocolos de sincronizacion de estros basados en progestagenos, sobre la respuesta reproductiva de ovejas Pelibuey. Para ello, 28 y 24 ovejas durante dos anos consecutivos, fueron sometidas a un protocolo de sincronizacion; el primer grupo (BAJA) recibio un CIDR durante siete dias y a su retiro se administro 0.125 mg de Cloprostenol y eCG a una dosis i.m. de 300 U. El segundo grupo (ALTA) recibio el mismo protocolo con una modificacion, el empleo de una dosis de 400 U de eCG. Para evaluar las variables obtenidas, se realizo la prueba exacta de Fisher (datos en porcentaje) o analisis de varianza. No existieron diferencias (P>0.05) entre grupos para el porcentaje de ovejas en estro (92.31%), la tasa de concepcion total (82.69%) y de las ovejas con estro sincronizado (87.50%). Adicionalmente, el inicio del estro (47.75±1.43 h) y la prolificidad (1.86 crias/parto) fue similar (P>0.05) entre grupos. En conclusion, los protocolos de sincronizacion de estros para ovejas Pelibuey que utilizan CIDR por siete dias, pueden emplear eCG a una dosis de al menos 300 U, sin afectar sus indicadores reproductivos asociados.

This study aimed to evaluate productive indicators of growth, carcass aspects and the proximal composition of the meat of the Guinea Fowl (GF) reared under tropical conditions in Mexico. It was carried out from July 2016 to May 2017. The productive behavior (PB) of 100 keets in 14 weeks was evaluated and for the trait of the carcass (TC) samples of 5 males and 5 females were analyzed. It was evaluated in PB, Weight gain (WG), feed consumption (FC) and feed conversion (FCO) and in TC, carcass yield (CY), water retention capacity (WRC), pH and color. Descriptive statistics were performed and a generalized linear model (GLM) was used to detect differences between sexes, using the SAS statistical package (Ver. 9.4). The final average weight was 1161.56 ± 94.82 g with a WG of 10.98 ± 0.95 g/bird, FC of 62.04 ± 2.48 g and an FCO of 5.65 ± 0.57 g. Males were superior (79.3%) in the CY, without statistical differences (P> 0.05). The WRC and the pH were very similar. GF production is an alternative meat supply being a source of animal protein.

34 Alpine goats were used with the objective of evaluating the effect of energy density in the diet, on the return to postpartum ovarian activity. Three experimental groups were formed: E80: 80% of the postpartum energy requirements, E100: 100% of the requirements and E120: 120% of the requirements. The diet was provided 3 weeks before and up to 60 days after delivery. Female weight was determined every five days and the ovaries were scanned by ultrasonography twice a week to assess follicular growth. The day the females ovulated was determined by radioimmunoassay, based on the progesterone concentration. The goats in E120, observed higher weights than in E80 and E100 (P≤0.05). In E100 the first follicle presented earlier (27.09 ± 08.5 days; P≤0.05) and presented the highest percentage of ovulation (54.54%). There were no differences in the calving-ovulation interval between E100 and E120 (P <0.05). The level of energy consumption in the diet stimulates postpartum ovarian activity; however, a low percentage of animals ovulate, which may indicate that there are other factors that can condition the complete recovery of the ovary, such as suckling.
