El objetivo del presente trabajo fue determinar la calidad de leche ganado bovino en el municipio Tarímbaro, Michoacán. se realizó Septiembre a Diciembre 2012 Michoacán con 100 hatos lecheros raza Holstein Friesian y criollo. Se tomó una muestra bote recepción cada hato, las cuales fueron transportadas al laboratorio bacteriología FMVZ UMSNH para su procesamiento. encontró que 70% muestras cumplen lo establecido Norma NMX-F-700-COFOCALEC-2004, mientras resto (30%) no cumple. Respecto México...
La mastitis es una patología, generalmente en el ganado bovino lechero. El objetivo de este trabajo fue aislamiento patógenos causantes vacas lecheras. estudio se realizó 14 hatos lecheros la raza Holstein-Friesian. Para toma muestras leche, utilizaron frascos plástico esterilizados con tapón hermético los cuales previamente anotó identificación necesaria del establo. procesamiento las leche obtenidas día muestreo. Las fueron sembradas agar 110 estafilococos, sangre azida y Mc Conkey....
Mastitis is the most frequent and expensive disease in Animal Production Units (UPAS-Animal Units) of dairy cattle, due to its serious consequences on economic losses quantity quality milk produced.Its cause directly related aspects well-being, health hygiene sanitation high milkproducing animals.In this work, important be taken into account for diagnosis, prevention, treatment, antimicrobials finally vital importance prevent bovine mastitis UPAS cattle are described.
This study provides the first description of autumn migration routes juvenile Short-toed Eagles Circaetus gallicus tagged in southeastern Spain. Three nestlings were with Argos/GPS satellite transmitters, which two reached their wintering grounds Mali, close to Inner Niger Delta. Onset, duration and differed between individuals, but both eventually settled approximately same area (c. 170 km apart). The located more than 2500 away from breeding sites, although birds covered some 3800–4700...
Abstract The aim of this study was to assess whether vulvar morphometric changes occurring in female pigs during proestrus and oestrus could be objective, accurate predictive indicators the onset thus performed artificial inseminations at most appropriate time. For that purpose, pictures vulvas from 60 hyperprolific females (30 gilts 30 sows) were taken once a day. Vulva measurements (area, perimeter, length width) on these using image processing ImageJ software. Gilts sows showed...
Summary The aim of this study was to determine the histomorphological changes that occurred in response two treatments for oestrus synchronization three different regions gilt's uterine tubes epithelium: ampulla ( AMP ), ampulla–isthmic junction AIJ ) and isthmus IST ). Nine prepuberal gilts were divided into groups n = 3): (1) e CG 400 IU h 200 (e /h (2) progesterone agonist P 4) (3) control group. number secretory cells (stained with periodic acid– S chiff reaction or PAS ‐positive cells)...
Summary We evaluated the effect of glycerol on perinuclear theca (PT) boar sperm. Samples from six ejaculates obtained three different boars were incubated in detergent Brij 36-T. Spermatozoa treated with a concentration either 2 or 4%, and for 10 30 min; two other samples protease inhibitors (PI; leupeptin an inhibitor commercial cocktail), mixed 4% glycerol, min. A third glycerol-free group was used as control. The processed electron microscopy evaluation. PT remained intact 78% control...
At the beginning of 1980s, a series very profound changes were initiated in milk cow nutrition approaches, as consequence highest levels production per that reached by productive systems northern hemisphere. Nutrition is defined processes through which an organism acquires and assimilates food to promote its growth replace worn or damaged tissues. The nutrients are fundamental for animals carry out their different functions. When we consider aspects touch field ruminants, understand...
The aim was to assess the reproductive efficiency of different techniques used preserve spermatozoa in artificial insemination semen doses (AI-doses) by evaluating refrigeration at 15°C, cryopreservation and encapsulation. Forty-two hyperprolific sows were treated with buserelin inseminated once a single fixed time. fertility rate, embryonic vesicles viability early mortality (arrested conceptuses) evaluated post-mortem 24th day pregnancy, analysed order effectiveness each proposed...
El estres oxidativo de los espermatozoides, se refiere al dano que pueden sufrir en la integridad sus componentes estructurales y fisiologicos; cuyo efecto esta directamente relacionado con disminucion sobrevivencia capacidad fecundante despues ser eyaculados. oxidativo, es provocado por formacion gran cantidad especies reactivas oxigeno (ROS) o moleculas contienen radicales libres, las cuales hacen presentes durante el manejo manipulacion del eyaculado, comprometiendo viabilidad...
The study evaluated the influence of age (30, 60, 90 and 120 days) on dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), free condensed tannins (FCT), fiber-bound (FBCT), protein-bound tannin content (PBCT), in vitro degradation rate DM (DMkd), CP (CPkd) NDF (NDFkd) Morus alba (MA) Hibiscus rosa-sinensis (HRS). For MA leaves, there was a quadratic (p < 0.01) relationship between age: days-old leaves similar, but it lower than that 30 leaves. HRS decreased linearly as...
Two groups were formed in order to evaluate the effect of an obesogenic diet on body and liver weight, fat accumulation histometric characteristics testicles New Zealand rabbits during peripuberal period.One group received a standard farm other with canola oil added.During study, weight both was recorded.At end euthanized liver, testicles, visceral, scapular scrotal weighed.Tissue samples obtained from carry out analysis.Body mass index, visceral significantly different (P<0.01) when...
During seminal freezing, sperm undergo oxidative stress, reducing their motility, viability, and acrosomal integrity. To prevent these damages, antioxidants have been added at the time of freezing. The objective was to assess antioxidant effect combination α-tocopherol with quercetin, diluent for freezing boar semen. semen boars Pietrain York/Pietrain breeds frozen in 0.5 ml straws, before a concentration 4 mg/ml (T1), quercetin concentrations 25, 50 100 µM (T2, T3 T4), + Quercetin 25 µM,...
Staphylococcus aureus se considera el principal agente causal de la mastitis bovina, que afecta a producción leche en las vacas. Para determinar presencia subclínica y frecuencia infección caracterización los fenotipos presentes S. aureus. Por conveniencia, obtuvieron 580 muestras compuestas vacas del sistema familiar baja escala. Identificar patógenos asociada caracterizar Los resultados evaluaron mediante prueba estimación proporciones (p<0,05). La subclínicas fue 24% 9% clínicas total...
El objetivo del presente trabajo fue determinar la calidad microbiológica de leche ganado bovino población Chiquimitio municipio Morelia, Michoacán a través cuenta bacterias mesófilas aerobias y organismos coliformes. Se recolectaron 50 muestras bote recepción igual número hatos lecheros obtenidos durante ordeña matutina; Las fueron analizadas técnica vaciado en placa, para Organismos Coliformes (OC) Bacterias Mesófilas Aerobias (BMA). Los resultados el conteo Unidades Formadoras Colonias...

Animal reproductive biotechnology, represents an opportunity to optimize the potential and productive animals. The aim of this paper is a brief review biotechnology in animal reproduction with future possibility application thepotential animals, such as vitro fertilization, cloning transgenesis.
Despite the advances that exist today on feasible technologies applied in breeding and animal production, few farmers or ranchers have shown concern for improving general environmental conditions of their Units Animal Production, without taking into account these are largely responsible health, welfare altering them impacting significantly presence problems reproductive productive nature, increasing production costs dairy industry. In this paper, some nutritional causes can cause disorders...
