The environmental sustainability of beef production is a significant concern within the food production system. Tannins (TANs) can be used to minimize the environmental impact of ruminant production because they can improve ruminal fermentation and ruminants’ lifetime performances and mitigate methane (CH4) emissions. The objective of this study was to evaluate the effects of dietary supplementation with TANs as sustainable natural alternative to reduce the environmental impact on growth performance, rumen fermentation, enteric CH4 emissions, and nitrogen (N) use efficiency of beef cattle through a meta-analysis. A comprehensive search of studies published in scientific journals that investigated the effects of TANs’ supplementation on the variables of interest was performed using the Scopus, Web of Science, and PubMed databases. The data analyzed were extracted from 32 peer-reviewed publications. The effects of TANs were assessed using random-effects statistical models to examine the standardized mean difference (SMD) between TANs’ treatments and control (non-TANs). The heterogeneity was explored by meta-regression and subgroup analysis was performed for the covariates that were significant. TANs’ supplementation did not affect weight gain, feed consumption, feed efficiency, or N use efficiency (p > 0.05). However, it reduced the concentration of ammonia nitrogen in rumen (SMD = −0.508, p< 0.001), CH4 emissions per day (SMD = −0.474, p< 0.01) and per unit dry matter intake (SMD = −0.408, p< 0.01), urinary N excretion (SMD = −0.338, p< 0.05), and dry matter digestibility (SMD = −0.589, p< 0.001). Ruminal propionate (SMD = 0.250) and butyrate (SMD = 0.198) concentrations and fecal N excretion (SMD = 0.860) improved in response to TANs’ supplementation (p< 0.05). In conclusion, it is possible to use TANs as a CH4 mitigation strategy without affecting cattle growth rate. In addition, the shift from urinary to fecal N may be beneficial for environment preservation, as urinary N induces more harmful emissions than fecal N. Therefore, the addition of tannins in the diet of beef cattle could be used as a sustainable natural alternative to reduce the environmental impact of beef production.

The objective was to analyze the effects of adding anthocyanin delphinidin-3-O-sambubioside and cyanidin-3-O-sambubioside of Hibiscus sabdariffa L. in animal diets. Scientific articles published before 2021 in clinics, pharmacology, nutrition, and animal production were included. The grains/concentrate, metabolic exigency, and caloric stress contribute to increasing the reactive oxygen species (ROS); the excess of ROS unbalance the oxidants and antioxidants. Cyanidin-3-O-sambubioside and delphinidin-3-O-sambubioside have antioxidant, antibacterial, antiviral, and anthelmintic activities. In the rumen, anthocyanin might show interactions and/or synergisms with substrates, microorganisms, and enzymes which could reduce the fiber degradability, but increase the potential methane (CH4) emissions; since anthocyanin interferes in the biohydrogenation of fats, they increase the fat milk and meat quality. Anthocyanins reduce plasma oxidation and deposit in tissues, increasing the milk and meat antioxidant activities. Cyanidin-3-O-sambubioside and delphinidin-3-O-sambubioside act as inhibitors of the angiotensin-converting enzyme (ACEi) and rennin expression which may improve milk yield (there is not enough evidence in ruminants, though). Polyphenols affect the reproductive potential. Sub products of HS contain as many amounts of polyphenols as calyces, and their inclusion in diets would positively affect the average daily gain and fat meat quality. Including HS in ruminant diets can improve the meat and milk quality.

The objective of this study was to determine the effects of the supplementation of a polyherbal mixture (HM) on the productive performance, carcass characteristics, meat quality, and the profile of blood metabolites of lambs fed a high-concentrate diet. Thirty-six male Pelibuey lambs (25.21 ± 0.96 kg BW) were housed in individual pens during a 56-day feeding period and were randomly assigned to four treatments: (1) Control (CON): Basal diet without HM; (2) HM1: CON + 1 g of HM kg−1 dry matter (DM); (3) HM2: CON + 2 g of HM kg−1 DM; and (4) HM3: CON + 3 g of HM kg−1 DM. Data were analyzed using the GLM (General Linear Model) procedure of statistical analysis system (SAS), and linear and quadratic effects were tested to evaluate the effects of the HM level. A quadratic increase was observed in the dry matter intake and in daily weight gain (p < 0.05) of lambs fed with HM2 and HM1, respectively. However, final body weight, body condition, carcass characteristics, and meat quality were similar among treatments (p > 0.05). It was observed a linear increase (p < 0.05) in the mean corpuscular hemoglobin concentration. Lymphocytes in blood from lambs supplemented with the HM1 diet increased and segmented neutrophils decreased compared to lambs receiving the CON treatment (p < 0.05). The concentration of uric acid in the blood had a linear increase (p < 0.05) and the serum creatinine level decreased (p < 0.05) as the HM dietary dose increased. In conclusion, dietary inclusion of 2 and 1 g of HM kg−1 of DM improves feed consumption and daily weight gain, respectively, without affecting carcass characteristics, meat quality, and health status on finishing lambs.

Introducción: El objetivo del presente estudio, fue evaluar el efecto de la adición de β-mananasa sobre el consumo de materia seca (CMS) en los periodos pre y posparto, la producción (PL) y calidad de la leche, el contenido de nitrógeno ureico (NU), y el conteo de células somáticas (CCS) en leche de vacas Holstein-Friesian.Método: En el estudio se utilizaron 30 vacas (Peso vivo (PV)=781±83 kg; de más de dos lactancias) de aproximadamente 260 d de gestación, las cuales se estratificaron por PV y PL en la lactancia previa y se asignaron aleatoriamente a uno de dos tratamientos: 1) Dieta completa (Maíz-ensilado de Maíz), Control; y 2) Control+0.10% de β-mananasa (CTCZYME; Seoul, South Korea).Resultados: El CMS preparto no fue diferente (14.44±0.70 vs 15.66±0.70 kg d-1; p>0.05) entre tratamientos. En el posparto, de manera similar, no hubo diferencias (p>0.05) entre las vacas complementadas con las enzimas y las vacas Control. Por el contrario, PL fue mayor (42.66±1.31 vs 38.24±1.31 kg vaca-1 d-1; p0.05) ninguno de los componentes de la leche. Por el contrario, las vacas que se alimentaron con la enzima fueron más eficientes (p

An alternative method for sustainable production of natural forage resources is the use of silvopastoral systems. The study evaluated the impact of a seasonal sheep silvopastoral system on soil and vegetation of a pine-oak forest. The experiment was conducted in the municipality of Jilotzingo, in the State of Mexico, Mexico. The study was performed in Sierra de Las Cruces Mountains, part of the Trans-Mexican neo-volcanic belt. Altitudes were between 2756 and 2870 m. Climate is temperate sub-humid C(w) with rainfalls from June through September. Average annual precipitation is 2680 mm. The experimental plot was delimited in the pine-oak forest, and this area was grazed rotationally by Creole sheep (n = 8) during the rainy season. The microclimate was characterized by air temperature and relative humidity. Soil compaction, leaf litter and floristic composition were assessed before and after the silvopastoralism. The microclimate was more homogeneous in mixed forest than in grassland without trees for both temperature (coefficient of variation: 21.5 vs 24.8%) and relative humidity (coefficient of variation: 37.6 vs 39.3%). Soil compaction showed no significant differences between the condition before and after the silvopastoralism (1.05 vs 0.98 kg cm−2, respectively; P > 0.05). Leaf litter cover and depth were similar before than after the silvopastoralism (85 vs 88% and 7.6 vs 7.4 cm, respectively; P > 0.05). Plant types before silvopastoralism were 10.5% trees, 40.0% shrubs, and 49.5% herbaceous, presenting a balanced relative importance index, although higher values for Cornus excelsa (27.7%), Garrya laurifolia (17.5%), Symphoricarpos microphyllum (17.1%), Bromus carinatus (16.5%), and Smilax moranensis (16.5%). Micro-histological analysis confirmed that sheep selected herbaceous (S. moranensis), shrubs (C. excelsa, Viburnum stenocalyx), and trees (G. laurifolia, Prunus serotina, Crataegus mexican). Results indicate that the pine-oak forest favors the establishment of a sheep seasonal silvopastoral system. The plant diversity of the pine-oak forest provides sheep with a daily diet of herbaceous, shrubs and trees of nutrient quality. Sheep defoliation is selective and stimulates regrowth of some species sheep consume. They also favor and accelerate incorporation of organic matter into the soil due to feces deposition and trampling.
