En las ultimas decadas, se desarrollaron varias tecnologias en el area de la reproduccion animal. El semen sexado es una biotecnologia reciente que aun se encuentra en fase de estudio y perfeccionamiento en diversas etapas, debido a que el proceso de sexaje causa estres al espermatozoide, y lo deja mas sensible al proceso de almacenamiento; esto interfiere directamente en la fertilidad. Esta tecnologia, que llego a Brasil en 2004, viene ganando adeptos entre productores que desean producir animales mas homogeneos para el sacrificio o para la produccion lechera. El uso del semen sexado ha sido difundido en muchos rebanos del mundo, ya que se presenta como una tecnica con un direccionamiento mayor en la seleccion del sexo. Muchas tecnicas han sido utilizadas con el fin de buscar una mayor separacion de espermatozoides portadores de cromosomas X y Y, con minima agresion espermatica. De esta forma, la utilizacion del sexaje espermatico ha obtenido resultados en la aplicacion de biotecnologias de la reproduccion asistida, y con eso ha elevado la ganancia en el mejoramiento genetico y ha optimizado la productividad en el sexo escogido. Entretanto, aun existen muchas limitaciones, principalmente referentes al tiempo de exposicion, la taza de aprovechamiento y los resultados de tazas de gestacion en condiciones de campo. Por otro lado, la dosis de semen sexado puede costar de dos a ocho veces el valor de una convencional; asi mismo, su uso avanza en Brasil. EnglishThis study aimed to present a complete and updated review on the origin of sexed semen, as well as on the requirements and techniques of sperm sexing. In the last decades, several technologies were developed in the field of animal reproduction. Sexed semen is a recent biotechnology that is still under study and refinement in various stages, because the sexing process causes stress to the sperm, leaving it more sensitive to the storage process; this directly interferes with fertility. This technology, which arrived in Brazil in 2004, has been gaining support among producers who want to produce more homogeneous animals for slaughter or for dairy production. The use of sexed semen has been disseminated in many herds of the world, since it is a technique with better results in the selection of sex. Many techniques have been used in order to seek a greater separation of sperms carrying X and Y chromosomes, with minimal sperm aggression. In this way, the use of sperm sexing has obtained results in the application of assisted reproductive biotechnologies, which has increased the gain in genetic improvement and has optimized productivity in the chosen sex. In the meantime, there are still many limitations, mainly concerning exposure time, exploitation rate, and the results of pregnancy rates in field conditions.

EnglishBovine viral diarrhea virus (BVDV) is a pathogen that affects bovine health; it produces clinical signs such as bronchopneumonia, diarrhea, teratogenicity, and reproductive losses. This study aimed to determine seroprevalence and some other factors associated with exposure to BVDV in a total of 930 calves from 31 dairy herds in the Bogota savanna. The data of the herds, as well as individual information of the calves, were collected through an epidemiological survey. An ELISA test was used to detect antibodies to BVDV p80. Data were analyzed with frequency and descriptive statistics, univariate analysis, and a binary logistic regression model, in which confounding factors were evaluated through a comparison between crude and adjusted odds ratios (OR). The average seroprevalence of BVDV was 27.1% (range 0-90%); additionally, antibodies against BVDV were observed in 83.9% of the herds. The factors associated with exposure to BVDV were: 1) age of animals under 4 months (OR = 4.9; 95% CI: 2.52-9.56); 2) records of abortion of the mother (OR = 6.4; 95% CI: 3.91-10.46; p = 0.001); and 3) records of diarrhea (OR = 2.6; 95% CI: 1.58-4.46; p = 0.010). This study allowed confirming a high exposure to the virus in these herds and identifying some associated factors, which contributes to a better understanding of the epidemiology of the disease. portuguesO virus da diarreia viral bovina (VDVB) e um patogeno que afeta a saude bovina; produz sinais clinicos como broncopneumonia, diarreia, teratogena ","PeriodicalId":21407,"journal":{"name":"Revue De Medecine Veterinaire","volume":"47 1","pages":"63-73"},"PeriodicalIF":0.0,"publicationDate":"2017-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91362078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prevalence of ovarian cysts was 32%, distributed in follicular cysts (21%) and luteal cysts (11%). In addition, there was a correlation between the presence of cysts and body condition ≤ 3 (23%), presence of metritis (9%), and the use of hormonal products (10%). Ovarian cysts were clinically manifested through symptoms of anestrus in cows with luteal cysts (90%) and the presence of irregular estrus in cows with follicular cysts (40%).

Isoespintanol and thymol are molecules of natural origin with a high antioxidant activity, which makes them potentially useful for reducing semen oxidative stress during cryopreservation. This study aimed to evaluate the effect of isoespintanol and thymol on total antioxidant and enzymatic activity of equine semen diluted for freezing purposes. The semen of five Colombian creole horses was diluted in a freezing medium, divided into three aliquots that were randomly assigned to treatments with isoespintanol (40 μM), thymol (50 μM), or control (no antioxidant). Total antioxidant capacity (TAC) was evaluated using ORAC and FRAP tests. Catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activity were evaluated by enzymatic assays. The statistical evaluation was performed using mixed models, correlation analysis, and comparison of means by Tukey’s test. SOD and GPx activities were lower for isoespintanol (6.7 ± 2.2 U/ml and 0.16 ± 0.02 U/ml), compared to thymol (6.9 ± 2.2 U/ml and 0.20 ± 0.02 U/ml) and to control (7.2 ± 2.2 U/ml and 0.22 ± 0.02 U/ml) (p 0.05). Isoespintanol reduces SOD and GPx activity in equine semen diluted for freezing purposes.","PeriodicalId":21407,"journal":{"name":"Revue De Medecine Veterinaire","volume":"87 1","pages":"149-158"},"PeriodicalIF":0.0,"publicationDate":"2017-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75160787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
