Se estima que la población microbiana del contenido del rumen durante el proceso de digestión, podría situarse entre 10.000 y 50.000 millones de gérmenes por cada ml. Son fundamentalmente bacterias, protozoarios y hongos. Las bacterias pertenecen a gran variedad de géneros y especies, entre las que por lo menos 28 especies son funcionalmente importantes. Los protozoarios se encuentran en concentraciones menores, en torno a 1 millón por ml, y los hongos (levaduras y mohos) llegan a constituir más del 8% de la biomasa microbiana.It is estimated that the microbial population of rumen content during the digestion process, could stand between 10,000 and 50,000 million germs per ml. They are mainly bacteria, protozoa and fungi. The bacteria belong to a variety of genera and species, among those that at least 28 species are functionally important. Protozoa are found in lower concentrations, around at 1 million per ml, and fungi (yeasts and molds) reach constitute more than 8% of the microbial biomass.
Dentro de esta población, algunas especies, están especializadas en atacar los componentes de las fibras vegetales haciéndolas asimilables; utilizan para su crecimiento amoniaco, con el que construyen sus proteínas que después serán digeridas por el animal. Estas especies microbianas, en perfecta simbiosis con el hospedador, reciben a cambio un medio ambiente idóneo para su desarrollo, con condiciones como la ausencia de oxígeno, temperatura de 39 a 40ºC, pH comprendido entre 6 y 7, un grado de humedad adecuado, y sobre todo un casi continuo aporte de nutrientes para su desarrollo.Within this population, some species are specialized in attacking the components of plant fibers making them assimilable; they use for their growth ammonia, with the one that builds their proteins that will later be digested by the animal. These microbial species, in perfect symbiosis with the host, they receive in return an ideal environment for their development, with conditions such as the absence of oxygen, temperature from 39 to 40 ° C, pH between 6 and 7, a degree of adequate humidity, and above all an almost continuous contribution of Nutrients for its development.
Muchas de estas especies, entre ellas las celulolíticas, cuando las condiciones del medio ambiente no son las adecuadas para su desarrollo, forman esporas, y esperan a que las condiciones sean de nuevo favorables para eclosionar de nuevo. Otras, las que no tienen esta capacidad, ante condiciones adversas del medio, mueren. En general, las bacterias son muy sensibles a los cambios de pH, de modo que cuando se hace muy ácido obliga a la esporulación a las que tienen esta capacidad, mientras que las demás mueren.Many of these species, including cellulolytics, when environmental conditions are not suitable for their development, form spores, and wait for the conditions are again favorable to hatch again. Others, those that do not have this capacity, under adverse conditions from the middle, they die. In general, bacteria are very sensitive to pH changes, so when it becomes very acidic it forces the sporulation to those with this capacity, while the others die.
En los laboratorios especializados que estudian el comportamiento digestivo de los rumiantes y la capacidad nutritiva de los diferentes alimentos, el líquido ruminal se utiliza para investigar in vitro la fermentación de estos alimentos y sus productos finales de digestión que pasan al intestino.In specialized laboratories that study the digestive behavior of ruminants and the nutritional capacity of different foods, ruminal fluid is used to investigate in vitro the fermentation of these foods and their final digestion products that pass into the intestine.

La presente invención se ilustra adicionalmente mediante el siguiente ejemplo en modo alguno limitativo.The present invention is further illustrated. by the following example in any way limiting.
EjemploExample
En el presente ejemplo, se parte de la obtención del contenido del rumen en el momento del sacrificio de un animal, seccionando la panza del mismo y extrayendo dicho contenido ruminal (sólidos y líquidos). Dicho contenido ruminal se mezcla con leche ácida a volúmenes iguales, con lo que se acidifica hasta pH comprendidos entre 3 y 5, obligando a las especies celulolíticas a esporular, y al resto de microorganismos a morir.In the present example, we start from obtaining of the content of the rumen at the time of the sacrifice of an animal, sectioning the belly of the same and extracting said ruminal content (solids and liquids). Said ruminal content is mixed with milk acid at equal volumes, thereby acidifying to pH between 3 and 5, forcing cellulolytic species to sporular, and the rest of microorganisms to die.
Esta leche ácida se obtiene mediante la fermentación de leche pasteurizada sembrada con Lactobacíllus acidophílus, de modo que producen ácido láctico. Cualquier ácido orgánico o inorgánico podría usarse con el mismo fin, siempre que no sea especialmente bactericida, y que los pH logrados estén comprendidos entre 2,5 y 5,5.This acidic milk is obtained by fermentation of pasteurized milk seeded with Lactobacillus acidophílus , so that they produce lactic acid. Any organic or inorganic acid could be used for the same purpose, provided it is not especially bactericidal, and if the pH achieved is between 2.5 and 5.5.
Una vez acidificado el contenido del rumen, se siembra el conjunto sobre un sustrato rico en proteína, en concreto, harina de soja convenientemente humedecida, y se mezcla íntimamente. Por cada 100 kg de harina de soja se añaden 20 litros de la mezcla de rumen y leche ácida y además se incorporan 30 litros de agua potable para obtener un sustrato de fermentación de aproximadamente 150 kg.Once the content of the rumen is acidified, it sow the whole on a substrate rich in protein, in concrete, conveniently moistened soy flour, and mixed intimately 20 liters are added per 100 kg of soybean meal of the mixture of rumen and acidic milk and 30 are also incorporated liters of drinking water to obtain a fermentation substrate of approximately 150 kg
La masa así preparada se deja fermentar en un medio privado de oxígeno durante 4 a 6 días (microsilos), a una temperatura de entre 37 y 39ºC. Durante este tiempo se produce un intenso crecimiento de la flora seleccionada que termina formando esporas tras la fermentación, al volverse el medio disgenésico.The dough so prepared is left to ferment in a medium deprived of oxygen for 4 to 6 days (microsilos), at a temperature between 37 and 39 ° C. During this time there is a intense growth of the selected flora that ends up forming spores after fermentation, upon becoming the dysgenetic medium.
Con posterioridad, se deshidrata dicha masa en un secadero de aire caliente (entre 40 y 45ºC de temperatura). El tiempo de deshidratación es de 24 a 48 horas una vez puesto en el secadero y dependiendo de la fuerza de secado y cantidad de masa. Por último, se microniza y se envasa en sacos de plástico perfectamente sellados.Subsequently, said mass is dehydrated in a hot air dryer (between 40 and 45ºC temperature). He Dehydration time is 24 to 48 hours once placed in the dryer and depending on the drying force and amount of dough. Finally, it is micronized and packaged in plastic bags perfectly sealed.
Los microorganismos así preparados permanecen en forma de vida latente con capacidad de eclosionar de nuevo y producir fermentación, durante un periodo como mínimo de tres años, a temperatura ambiente. Si bien es recomendable su conservación en lugares secos y nunca bajo los rayos directos del sol.The microorganisms thus prepared remain in latent way of life with ability to hatch again and produce fermentation, for a period of at least three years, at room temperature. Although its conservation is recommended in dry places and never under direct sunlight.
Así, las esporas directamente seleccionadas del rumen, como las obtenidas por el proceso anteriormente descrito, son capaces de digerir la fibra siempre que se las sitúe en un medio idóneo.Thus, the spores directly selected from the rumen, like those obtained by the process described above, they are able to digest fiber whenever they are placed in a suitable medium.
