El rumen es un ecosistema complejo donde los nutrientes consumidos por rumiantes son digeridos mediante proceso de fermentación realizado microorganismos ruminales (bacterias, protozoos y hongos).Dichos están en simbiosis, debido a su capacidad adaptación e interacción, mientras el rumiante proporciona ambiente necesario para establecimiento estos proporcionan energía al animal, la que proviene productos finales fermentación.Dentro del rumen, coexisten entorno reducido pH cercano...
The differential expression of the Trichomonas vaginalis cysteine proteinase TVCP4 by iron at protein synthesis level and prediction an iron‐responsive element (IRE)‐like stem‐loop structure 5′‐region T. 4 gene ( tvcp4 ) mRNA suggest a post‐transcriptional mechanism regulation in trichomonads mediated IRE/IRP‐like system. Gel‐shifting, UV cross‐linking competition experiments demonstrated that this IRE‐like specifically bound to human regulatory protein‐1. IRP‐like cytoplasmic proteins...
Solid-state fermentation can be used to produce feeds for ruminants, which provide an enriched population of yeasts improve ruminal fermentation. Fermentation apple bagasse was performed obtain a yeast-rich product, with the objective isolating, identifying, and characterizing yeast strains testing their capability enhance in vitro fibrous feeds. Yeasts were isolated from fermented under conditions, using rumen liquor obtained cannulated cows alfalfa as substrate. A total 16 new identified...
The objective of this study was to identify and characterize yeast strains isolated from the ruminal ecosystem that are capable enhancing fermentation in bovines consume high-fibre diets recommended by livestock feed guidelines Cuba. yeasts were rumen Holsteincows had been fed a biofermented product. Isolated colonies purified, identified, characterized using biochemical molecular methods, their effects on compared measuring vitro gas production. Thirteen new production with potential use as...
Caracterizar el crecimiento ayuda en la toma de decisiones manejo, comercialización y mejoramiento genético. El objetivo fue identificar un modelo no lineal (MNL) para describir curva borregas registro a través siete razas. Se evaluó peso vivo, desde nacimiento hasta los 230 d edad, las razas Blackbelly (BB; n= 19,084), Pelibuey (PE; 39,025), Dorper (DR; 35,814), Katahdin (KT; 74,154), Suffolk (SF; 10,267), Hampshire (HS; 7561) Rambouillet (RB; 7,384). evaluaron MNL: Brody (BRO), Verhulst...
The aim of this work is to characterize the natural microflora artisanal Ranchero cheese and identify Lactococcus isolates. Ten samples made with raw milk were obtained from local producers located in different geographical areas. Aerobic mesophilic, Staphylococci, Psychrophilic , total coliforms, molds, yeast and, lactic acid bacteria (LAB) (Lactococcus Streptococcus mesophilic thermophilic, Lactobacillus Enterococcus, Leuconostoc) numbered through agar plating. LAB isolates classified by...
Oocyte developmental competence is the ability of a mature oocyte to be fertilized and subsequently support embryonic development. Such gained during folliculogenesis facilitated by bidirectional communication into compacted cumulus–oocyte complex (COC). Human tissue inhibitor metalloproteinases-1 (TIMP1) participates in biological processes, including cell growth, differentiation, apoptosis. This study aimed evaluate influence TIMP1 as growth factor on vitro maturation (IVM) culture bovine...
The aim of this study was to explore the relationships between a Gram-positive bacterial population and methane production in rumen dairy cows supplemented with monensin tallow, alone or combination. Under each treatment condition, following ruminal fermentation parameters were measured: pH, oxidation-reduction potential (ORP), VFA, production. Quantification bacteria present performed by amplifying 16S rDNA gene using PCR. Diversity analysis PCR–denaturing gradient gel electrophoresis...
En el Caballo de Pura Raza Española (CPRE), los objetivos selección son las disciplinas ecuestres en que se desenvuelve, y criterios medidas zoométricas (MZ). El objetivo este trabajo fue caracterizar CPRE con análisis componentes principales (ACP); estimar parámetros genéticos (PAG) para MZ, generados ACP. Las MZ analizadas 1806 individuos (n) fueron: perímetro torácico (PT), rodilla, caña, longitud escápulo – isquial (LEI), anchura pecho (AP), altura del hueco sub esternal (AHS), (ALP), a...
The aim of this study was to assess the effect inclusion fermented apple bagasse (FAB) obtained through solid state fermentation on pH, ammonia nitrogen (N-NH 3 ), volatile fatty acids (VFA) content, in vitro dry matter digestibility (IVDMD), lactic acid and microbial counting alfalfa hay under rumen environment; four levels FAB were evaluated (0, 0.25, 0.50 0. 75 g/dry FAB) replacing 1.5 g (DM) incubated at different times 4, 8, 12 24 h) using a complete random design with repeated measures...
Introducción: El agua es una sustancia indispensable para la vida por lo que se considera como el recurso natural más apreciado en planeta. En norte de México existe “Programa ambiental México-Estados Unidos: Frontera 2020”; cual participan instituciones mexicanas Junta Municipal Aguas y Saneamiento (JMAS) mientras parte los Estados Unidos Norteamérica Taskforce U.S., Agencia Ambiental (USEPA) Universidad Estatal Nuevo Mexico, entre otras (PAMEUF, 2013). dicho programa municipio Ascensión...
The objective of this study was to evaluate the microbial kinetics, fermentative and chemical characteristics during solid state fermentation (SSF) apple bagasse (AB), which determined over course 4 incubation times: 0, 24, 48, 72 h, in a completely randomized design with repetitions. pH values, lactic acid concentration, numbers total aerobic bacteria, yeast lactobacilli, dry matter digestibility neutral detergent fiber were determined. True crude protein, also measured. Results revealed...
Obtener ovocitos madurados in vitro, que sean competentes para fertilizarse y originar un porcentaje superior al 50 % de blastocitos viables, es una las principales metas existen en el desarrollo vitro embriones bovinos. Es por ello necesario entender los procesos celulares, desembocan la maduración del ovocito durante foliculogénesis su subsecuente transición embrión. La embrión proceso complejo involucra inactivación genómica activación genoma embrionario. Este se da bovinos etapa 8 a 16...
During germline establishment and its molecular control, the Figla gene, which codes a transcription factor, is preferentially expressed in oocytes, key for oogenesis/folliculogenesis, ovarian function, female fertility. However, specific subcellular localization (cytoplasmic or nuclear) of this factor unknown. We analyzed FIGLA protein using computer programs NucPred, SubCellProt, NLStradamus to predict localization; also, we established platform artificial expression murine gene cultured...
El objetivo fue identificar QTL asociados a polimorfismos de nucleótido único (SNP) cuya acción contribuya al desarrollo fenotípico productivo, reproductivo y salud del ganado lechero raza Holstein.

The microRNAs (miRNAs) that participate in regulating oocyte growth and oocyte-embryo transition must be identified characterised to understand maturation, fertilization embryo development mechanisms bovine reproduction.With the purpose of identifying new miRNAs may play a role maturation early embryogenesis, genome library from ovarian was developed.After analysing concatamers 40 clones, two were labeled bta-mir-8548 bta-mir-8549.These showed stable stem-loop structure accordance with...
Bouteloua gracilis es un pasto nativo del norte de México, que utilizado como fuente forraje para el ganado por su alto contenido nutritivo; tiene elevada tolerancia al estrés osmótico le permite vivir en climas secos; sin embargo, los mecanismos moleculares confieren esta aún no se han reportado. Existe una clase RNAs pequeños (sRNAs) llamados microRNAs (miRNAs), unen complementariedad a mensajeros blanco, etiquetándolos degradación o supresión la traducción. En este trabajo reporta...
The ashwin gene in Xenopus is expressed the neural plate, and later embryonic brain, eyes, spinal cord, regulates cell survival during gastrulation anterioposterior patterning. also maternally zygotically expressed, suggesting its importance embryo development. Here, bovine ASHWIN homolog was isolated from an ovary cDNA library. expression analysis of this by RT-PCR adult heart, lung, muscle, ovary, testis demonstrated ubiquitous 699 bp transcript.
