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 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.

An experiment was conducted to evaluate the effect of a polyherbal mixture based on Withania somnifera, Ocimum tenuiflorum, Tinospora cordifolia and Emblica officinalis, on lamb’s growth and blood metabolites. Thirty-two lambs (initial body weight BW 25 ± 4.1 kg) were randomly assigned to the treatments which consisted of the polyherbal ImmuPlus at dietary concentrations of 0, 0.1, 0.2 and 0.3% of dry matter (DM) for 60 days. There was a quadratic response to polyherbal in average daily gain (p < 0.01) and feed conversion (p < 0.05). The optimal concentration estimated by regression for maximum ADG was 0.14 ± 0.08% DM of ImmuPlus. Ruminal DM digestibility was not affected but pH was reduced linearly (p < 0.05). Ruminal N-NH3 (p < 0.01) and total VFA concentration showed a quadratic increment (p < 0.05) whereas butyrate proportion was increased linearly (p < 0.05). There was no effect in most blood metabolites related to energy metabolism, but uric acid was linearly reduced (p < 0.01) and bilirubin showed a quadratic decrement (p < 0.05). Mean corpuscular haemoglobin (p < 0.01) increased linearly (p < 0.10), lymphocytes and segmented neutrophils showed a quadratic response (p < 0.01) and platelets showed a linear reduction (linear p < 0.05). The inclusion of ImmuPlus improved the daily gain in finishing lambs and feed efficiency at 0.1% DM without altering blood chemistry and blood biometry.

To evaluate phenolic compounds and whether the combination of a tanniferous fruit and soybean oil could improve the performance, meat characteristics, and fatty acid (FA) profile in lambs, an experiment was conducted over 40 days with twenty creole male lambs (23.71±3.46 kg). The lambs were allotted in a completely randomised design, with factorial arrangement 2 × 2, with the following dietary treatments: (1) control diet, (2) 2%Caesalpinia coriariaground fruit dry matter (DM), (3) 2% soybean oil DM, and (4) 2%Caesalpinia coriariafruit plus 2% soybean oil. The concentration of condensed tannins (CT) inCaesalpinia coriaceawas 21.71 g/kg DM. No interactions were detected (P>0.05) among soybean oil andCaesalpinia coriaria, and there were no differences in daily gain, intake, and feed conversion. Soybean oil reduced (P<0.05) DM digestibility (68.05 versus 59.56%). In fat from thelongissimus thoracis et lumborum(LTL) muscle, only linoleic acid presented differences (P<0.05) between treatments. The combination ofCaesalpinia coriaceafruit and soybean oil did not improve lamb performance at the included levels.

•Supplementation in blocks increased dry matter digestibility in horses presumably by improving the fermentative capacity in the gut•Mineral supplementation did not affect gas production but slightly improved the in vitro digestibility AbstractThe effects of a mineral block for horses on in vivo digestibility and in vitro fermentability with equine fecal inoculum were evaluated. Fifty healthy horses from three groups (lactating mares n=19, working horses n=18 and maintenance horses n=13) were randomly assigned to two treatment groups (with or without the mineral block; Ca 10.0%, P 12.0%, Zn 12.1 mg/kg, Cu 2050 mg/kg, Mn 4050 mg/kg, Se 30 mg/kg and I 105 mg/kg). Dry matter digestibility was estimated with an internal marker. Samples of diet were incubated with equine fecal bacteria with varying amounts of mineral block (0, 1.1, 3.6 and 6.2 mg /g dry matter DM) to record gas production and to estimate in vitro DM digestibility. The results showed that mineral supplementation with the blocks increased in vivo DM digestibility (P < 0.01) in all groups, but there was an interaction (P < 0.01) with a greater response in the maintenance horses (55.5 vs. 78.0%) compared to lactating mares (62.8 vs. 79.6%) and working (70.3 vs. 75.1%). Block consumption was lowest in the lactating mares (12.8 g/d), intermediate in the working horses (44.6 g/d) and highest in the maintenance horses (74.2 g/d). The mineral supplementation did not affect the kinetics of gas production but tended (P = 0.10) to improve the in vitro DM digestibility (37.01 vs. 38.34%). Mineral block supplementation increased dry matter digestibility in horses. The unsupplemented control diet was deficient in several minerals, and block intake was not proportional to the mineral requirements.

Toxocariasis is a zoonotic disease that poses a threat to public health worldwide. This disease primarily affects children and is caused by the presence in the digestive tract of a common roundworm of dogs, Toxocara canis, or cats, Toxocara cati. Toxocara is responsible for the presentation of various syndromes in humans depending on the affected organs. In this study, the prevalence of anti-T. canis antibodies was investigated in children aged 3-16 years from semirural populations in the municipalities of Amecameca and Chalco in México. An ELISA was used to determine the presence of anti-T. canis antibodies in blood samples. Of the 183 sera obtained for this study, 22 were positive for anti-T. canis antibodies (12.02%). Of these, 6.50% were from males and 5.4% were from females. Risk factors were investigated and it was found that living near a cattle operation had a statistically significant association with (Chi(2) = 5.51 and p = 0.01) and was a risk factor for (OR = 4.25, p = 0.02) seropositivity to T. canis. Keeping dogs with short hair (Chi(2) = 3.24 and p = 0.07) showed a tendency toward seropositivity for T. canis, as did the habit of sleeping with pets (Chi(2) = 3.46 and p = 0.06). Seropositivity to T. canis was confirmed in children in the Amecameca and Chalco regions of México and the risk factors were identified. These findings provide important insight into the prevalence and spread of this zoonotic parasite.

Digestion of cell wall fractions of forage in the rumen is incomplete due to the complex links which limit their degradation. It is therefore necessary to find options to optimize the use of forages in ruminant production systems. One alternative is to use exogenous enzymes. Exogenous fibrolytic enzymes are of fungal or bacterial origin and increase nutrient availability from the cell wall, which consists of three fractions in different proportions depending on the species of forage: digestible, potentially digestible, and indigestible. The response to addition of exogenous enzymes varies with the type of forage; many researchers infer that there are enzyme-forage interactions but fail to explain the biological mechanism. We hypothesize that the response is related to the proportion of the potentially digestible fraction. The exogenous enzyme activity depends on several factors but if the general conditions for enzyme action are available, the potentially digestible fraction may determine the magnitude of the response. Results of experiments with exogenous fibrolytic enzymes in domestic ruminants are inconsistent. This, coupled with their high cost, has made their use unattractive to farmers. Development of cheaper products exploring other microorganisms with fibrolytic activity, such asFomes fomentariusorCellulomonas flavigena, is required.
