Objetivo. Determinar las variables fermentativas in vitro de un consorcio bacteriano celulolítico (CBC) aislado de una búfala de agua en cocultivo con bacterias ruminales totales (BRT) en sustratos fibrosos. Materiales y métodos. Un CBC se aisló de fluido ruminal de una búfala de agua en medios selectivos celulolíticos. El diseño experimental fue un diseño completamente al azar con arreglo factorial 3x2, los factores fueron tratamientos [BRT, CBC y un cocultivo (BRT + CBC)] y sustratos (pasto pangola y rastrojo de maíz). La producción de gas total y metano (CH4) se midieron a diferentes intervalos de tiempo. Además, se estimó pH, nitrógeno amoniacal (N-NH3), degradación de materia seca (DMS) y de fibra detergente neutro (DFDN), y la población de bacterias totales a 72 h de incubación. Resultados. El cocultivo produjo mayor (p≤0.05) cantidad de gas a las 3, 6 y 24 h en ambos sustratos. A las 48 y 72 h, el cocultivo produjo mayor (p≤0.05) gas en pasto cobra. El cocultivo y las BRT no presentaron diferencias (p>0.05) en la producción de CH4 a 48 y 72 h, y en DMS y DFDN (p>0.05). En el pasto cobra, la concentración de N-NH3 con el cocultivo fue mayor (p≤0.05) que con BRT. Conclusión La producción de gas y degradación de materia seca de los consorcios bacterianos celulolíticos procedentes del rumen de una búfala de agua muestran que son una alternativa para mejorar la fermentación de carbohidratos estructurales del pasto cobra cuando se cocultivan con bacterias ruminales bovinas.

“…(2002) reported that sheep fed diets with the CT-containing forage L. corniculatus (3.2% CT DM) had lower populations of proteolytic bacteria and thus reduced proteolysis in the rumen. Moreover, CT-containing diets reduced ammonia-N concentrations in sheep (Christensen et al., 2016) and increased plasma essential amino acids out-flow from the rumen into the small intestine. In the present study, goats supplemented with PS had a linear reduction of rumen ammonia-N concentration compared to goats fed the control diet.…”

The aim of this study was to determine the effects of tannin-rich peanut skin (PS) supplementation on growth performance, ruminal and blood metabolites, and carcass traits associated with internal parasite infection in meat goats under confined conditions. Twenty-one Kiko crossbred male goats were blocked by body weight (BW) and randomly assigned to one of 3 treatment groups. Experimental diets contained different levels of peanut (Arachis hypogaea) skin replacing alfalfa (Medicago sativa) pellets (ALP) in a control diet. Experimental treatments included: 30% ALP (control), 15% PS and 15% ALP, and 30% PS. Peanut skin was incorporated in the grain mix portion of the diets. Animals were fed once daily, and the intake was adjusted every 3 to 4 d. Each animal was each artificially infected with 5,000 larvae of the 3rd stage of barber's pole worm (Haemonchus contortus). Body weights, dry matter intake (DMI), and fecal samples for fecal egg counts (FEC) were taken at d 0, 12, 23, and 41. Rumen fluid and blood samples were collected at d 45. The performance period lasted 45 d and at the completion of the study, goats were harvested, and carcass characteristics, abomasal worm counts were measured. The results showed that DMI, BW, carcass traits, and meat color were not affected by PS supplementation, whereas average daily gain (ADG, P < 0.01), blood glucose (P < 0.001), phosphorus (P < 0.05), and cholesterol levels (P < 0.001) significantly increased with increasing levels of PS supplementation. There was a linear (P < 0.01) reduction in rumen acetate to propionate ratio, ammonia-nitrogen, FEC, and H. contortus worm counts, with increasing levels of PS supplementation. This study shows that PS supplementation up to 30% of the diet can improve ADG and rumen fermentation while reducing gastrointestinal parasite infection in meat goats.

“…Lotus species, rich in CT, have been demonstrated to provide different benefits, such as favoring the weight gain, the growth of wool, improvement of the production and composition of milk and reducing the number of anthelmintic products in farming animals [ 81 ]. In cattle, the production of methane was reduced and enhanced ruminal fermentation when the animals were fed with Lotus corniculatus , which was attributed to the CT [ 82 ]. The administration of L. corniculatus has shown positive effects on milk production and gastrointestinal function of sheep [ 80 ].…”

Tannins are polyphenolic compounds historically utilized in textile and adhesive industries, but also in traditional human and animal medicines or foodstuffs. Since 20th-century, advances in analytical chemistry have allowed disclosure of the chemical nature of these molecules. The chemical profile of extracts obtained from previously selected species was investigated to try to establish a bridge between traditional background and scientific data. The study of the chemical composition of these extracts has permitted us to correlate the presence of tannins and other related molecules with the effectiveness of their apparent uses. The revision of traditional knowledge paired with scientific evidence may provide a supporting background on their use and the basis for developing innovative pharmacology and food applications based on formulations using natural sources of tannins. This traditional-scientific approach can result useful due to the raising consumers’ demand for natural products in markets, to which tannin-rich extracts may pose an attractive alternative. Therefore, it is of interest to back traditional applications with accurate data while meeting consumer’s acceptance. In this review, several species known to contain high amounts of tannins have been selected as a starting point to establish a correlation between their alleged traditional use, tannins content and composition and potential bioaccessibility.
