“…Tannin concentrations above 2% of DM in the diet can reduce DM intake and, consequently, animal performance [10,41]. Consequently, the results obtained in the present study were consistent because the inclusion of a low concentration of hydrolyzable tannins did not affect the DMi and ADG.…”

“…However, they have been banned because of the possibility of increase in bacterial resistance and issues with human health [8]. Thus, phytogenic additives, such as essential oils and tannins, could be a better choice because they have antimicrobial properties and can reduce the concentration of ruminal ammoniacal nitrogen, increasing the efficiency of N utilization, as with the use of essential oils [9,10].…”

The objective of this study was to evaluate the intake and digestibility of nutrients, emission of enteric CH4, and productive performance of Nellore bulls grazing Urochloa brizantha cv. Marandu palisade grass pastures during the rainy season, receiving an energy supplement or mineral supplement, with or without the inclusion of phytogenic additives. Forty-eight Nellore bulls were treated with: (1) energy supplement without the inclusion of phytogenic additives; (2) energy supplement with the inclusion of phytogenic additives; (3) mineral supplement without the inclusion of phytogenic additives; and (4) mineral supplement with the inclusion of phytogenic additives. Consumption of total dry matter (DM), crude protein (CP), apNDF, and energy; digestibility of DM, CP, and energy; average daily gain; stocking rate; and gain per area were higher in animals consuming energy supplements than those consuming mineral supplements. Digestibility of DM, NDF, and energy levels were lower in animals that consumed phytogenic additives. Compared with mineral supplements, the supply of energy supplements provides higher nutrient intake, increases enteric CH4 emission, and improves nutrient digestibility, providing a greater productive performance. The inclusion of phytogenic additives negatively affected nutrient intake and digestibility, did not reduce enteric CH4 emission, and influenced productive performance.

“…Beauchemin et al [ 67 ] also highlighted that harvesting forage at an earlier maturity stage is a strategy that can be used to decrease enteric CH 4 production. Meister et al [ 68 ] also found that CH 4 production for Panicum maximum cv Tanzania increases linearly with the number of grazing days, possibly reflecting a reduction in quality. De Souza Filho et al [ 69 ] revealed that the intensity of defoliation affected CH 4 production in the tropics, and a target height of 230–300 mm has the potential of reducing CH 4 emissions by 13–14%.…”

The demand for dairy products is ever increasing across the world. The livestock sector is a significant source of greenhouse gas (GHG) emissions globally. The availability of high-quality pasture is a key requirement to increase the productivity of dairy cows as well as manage enteric methane emissions. Warm-season perennial grasses are the dominant forages in tropical and subtropical regions, and thus exploring their nutritive characteristics is imperative in the effort to improve dairy productivity. Therefore, we have collated a database containing a total of 4750 records, with 1277 measurements of nutritive values representing 56 tropical pasture species and hybrid cultivars grown in 26 different locations in 16 countries; this was done in order to compare the nutritive values and GHG production across different forage species, climatic zones, and defoliation management regimes. Average edaphoclimatic (with minimum and maximum values) conditions for tropical pasture species growing environments were characterized as 22.5 °C temperature (range 17.5–29.30 °C), 1253.9 mm rainfall (range 104.5–3390.0 mm), 582.6 m elevation (range 15–2393 m), and a soil pH of 5.6 (range 4.6–7.0). The data revealed spatial variability in nutritive metrics across bioclimatic zones and between and within species. The ranges of these nutrients were as follows: neutral detergent fibre (NDF) 50.9–79.8%, acid detergent fibre (ADF) 24.7–57.4%, crude protein (CP) 2.1–21.1%, dry matter (DM) digestibility 30.2–70.1%, metabolisable energy (ME)3.4–9.7 MJ kg−1 DM, with methane (CH4) production at 132.9–133.3 g animal−1 day−1. The arid/dry zone recorded the highest DM yield, with decreased CP and high fibre components and minerals. Furthermore, the data revealed that climate, defoliation frequency and intensity, in addition to their interactions, have a significant effect on tropical pasture nutritive values and CH4 production. Overall, hybrid and newer tropical cultivars performed well across different climates, with small variations in herbage quality. The current study revealed important factors that affect pasture nutritive values and CH4 emissions, with the potential for improving tropical forage through the selection and management of pasture species.

“…Waghorn & Clark (2011), stated that diets containing high fibre concentrations and very low CP contents are not optimal for high-producing ruminants. Since, it implies a longer retention time in the rumen owing the lower rate of passage, thus leading to greater CH4 emission (Meister et al, 2021).…”

“…Livestock plays an important role in the livelihoods of rural households and the economies of developing countries (McDermott, Staal, Freeman, Herrero, & Van de Steeg, 2010;Herrero et al, 2013;Thornton & Gerber, 2010;Do-Lam, Trung-Thanh, & Grote, 2019;Torres, Heredia-r, Toulkeridis, & Estupiñ, 2022). Nevertheless, meat and dairy production in arid, equatorial and tropical regions is often lower than productive in temperate regions due to the lower nutritional quality of forage grasses, infertile soils and adverse climatic conditions (Lee, Davis, Chagunda, & Manning, 2017;B, Heredia-r, Valencia, & Torres, 2021;Meister et al, 2021). Sustainable intensification as a form of production wherein yield increase without adverse environmental impact and without the cultivation of more land, are being largely considered (Barreto-álvarez, Heredia-rengifo, Padillaalmeida, & Toulkeridis, 2020; Nicolás et al, 2018).…”

Grazing management is a key element to optimize growth cycle of forages, which are enhanced in their chemical composition leading to the reception of greater nutritive values for feeding ruminants. Several studies have showed that the accuracy and precision of the feeding values are critical to achieve this goal, unfortunately, in Ecuador there are not referential data, despite of Megathyrsus maximus is the most forage used by livestock farmers. The predominant aim of the current study was to approach and estimate the feeding values by INRA feed evaluation system of Tanzania grass (Megathyrsus maximus) subjected at different grazing strategies. The statistical design was a randomized complete block, with a 3 × 2 factorial arrangement. Where the treatments were combinations of three grazing frequencies (GF) (30 d; termed GF30, 45 d, GF45 and 60 d, GF60) and two cutting heights (CHs; 30 and 45 cm). The agronomic data did not vary by season effect (P = 0.24 to 0.82), but GF60 had higher plant heigh and dry matter (DM) contents (P < 0.001) than other GF, although with less tiller populations (241 vs. 304 tiller/m2). By CHs effect, Tanzania grass at 30 cm had a greater DM content than 45 cm of CHs (5565 vs. 4221 ± 603 kg/ha-1; P = 0.073). All chemical determinations were affected by GF, CHs and their interaction (P < 0.001 to 0.004) with the exception on ADF between CHs (P = 0.50). Whereas only the CP and ADF values were conditioned by season effect (P = 0.001 to 0.011). Subsequently, Tanzania grass subjected at moderate rest periods and low defoliation intensities showed greater energy and proteins values than traditionally used GF60. Based in these findings, the defoliation frequency had influence on agronomic and chemical characteristics, whilst the feeding values was mainly affected by grazing intensities and weather conditions. So, the best combination regarding nutritive values should be at GF30 and GF45 combined with 45 cm of CHs.
