“…Protein supplements can be composed by two protein sources: true protein and NPN. True protein sources have different RDP contents, such as cottonseed meal and corn gluten, which have about 65 and 18% RDP in their composition, respectively [66].…”

“…In pasture production systems, it is necessary to optimize the use of nutrients and forage digestibility to maximize weight gain, even though the supplement promotes direct input of nutrients required by animal [66]. In this scenario, protein supplementation can increase forage intake due to the supply of N-NH 3 to ruminal microorganisms, and a consequent increase in energy intake, responsible for the increase in animal performance.…”

“…However, corn is an ingredient traditionally consumed by humans and monogastric animals which, in the context of system sustainability, generates competition between livestock and society [70]. Likewise, cottonseed meal and soybean meal are the most conventionally used protein ingredients in animal feed, due to the high CP content, which varies between 30 and 50%, and RUP, which contributes to increase the protein flow to the intestine [71][72][73]. Despite being important protein sources, they are costly ingredients that increase the production costs of beef cattle systems.…”

“…An alternative protein ingredient is dried distillers' grain with soluble (DDGs), a co-product of ethanol from corn or sorghum production, which has been gaining attention in animal nutrition for meeting the energy and protein demands of diets in pasture or feedlot systems [71]. In Brazil, however, most industries produce DDG without soluble, resulting from dry milling of corn processing for ethanol production [66]. DDG is typically characterized by its high protein content with low ruminal degradation, presenting between 50 and 62% of RUP in its composition, responsible for the greater supply of MP to the ruminant [86].…”

The increasing demand of meat requires the adoption of sustainable intensification livestock systems, applying nutritional strategies to reduce any negative contribution from beef cattle to global warming and, at the same time, to increase animal performance and productive efficiency. The pasture management practices and feed supplementation, mainly using non-edible feed with less costs, could minimize environmental and social impacts, resulting in higher productivity with less inputs utilization. Tropical grass submitted to grazing management according to plant height present high soluble protein and low levels of indigestible neutral detergent fiber contents. Energy or rumen undegradable protein supplementation, associated to alternative additives to antibiotics effects, such as probiotics, tannin, essential oils and saponin, can help to fully exploit the animal genetic potential and nutrient utilization efficiency, which decreases greenhouse gases emissions and improves animal performance. Hence, more information about these tools can make the livestock systems in tropical pasture more efficient and eco-friendlier.

“…Pasture intensification can be achieved through the adoption of diverse technologies, such as fertilization and pasture management, to optimize the forage consumed by animals, and animal supplementation [10][11][12]. In this study, pasture intensification refers to intensive grazing management acquired through a combination of increased stocking rate, N fertilization, and grazing management practices.…”

Intensive Production and Management of Marandu Palisadegrass (Urochloa brizantha ‘Marandu’) Accelerates Leaf Turnover but Does Not Change Herbage Mass

Pasture intensification through higher stocking rates, nitrogen fertilization and intensified grazing management in beef cattle production optimizes pasture use by increasing the forage harvested. We aimed to assess its effects on the morphogenesis and canopy structure of Urochloa brizantha ‘Marandu’ (marandu palisadegrass) pastures. The treatments consisted of marandu palisadegrass pastures managed under continuous stocking and a canopy height of 25 cm, with different levels of intensification: extensive, semi-intensive, and intensive systems N-fertilized with 0 kg, 75 kg, and 150 kg N ha−1 year−1, respectively, as ammonium nitrate (32% of N), with four replicates (paddocks) in a completely randomized design. Phyllochron (9.8 days) and leaf lifespan (34.7 days) were shorter in intensified pastures, whereas herbage mass was similar among treatments. Extensive pastures had a higher proportion of senescent material; thus, more intensive systems showed higher proportions of leaves and stems, although the leaves-to-stem ratio remained similar across production systems. The defoliation interval was lower in intensive (14.4 days) and higher in extensive (18.7 days) treatments. Thus, pasture intensification accelerates leaf appearance, decreases leaf lifespan, shortens the tiller defoliation interval and increased herbage accumulation rate but does not change herbage mass. The extensive system produces excessive forage losses due to dead material.

Ammonia, nitrous oxide and methane emissions from excreta of cattle receiving rumen undegradable protein

We hypothesized that supplementation with rumen undegradable protein (RUP) during the rearing phase mitigates nitrous oxide (N 2 O), methane (CH 4 ), and ammonia (NH 3 ) emissions from excreta of Nellore animals in Urochloa brizantha 'Xaraés' pasture. The treatments applied to soil were urine and dung of animals supplemented without RUP or with RUP in the middle and end of the rearing phase. We assessed N 2 O and CH 4 emissions using a static closed chamber and NH 3 emissions using the semi-open static chamber method. No effects were observed for supplement, excreta type, period, or interaction on N 2 O emissions. The mean emission factor was 0.03% of N in the excreta lost as N 2 O. Higher NH 3 losses were observed for the urine treatments in the end period, regardless of the supplement type. The mean NH 3 emission factor for urine was 2.96 and 13.8% for the middle and end periods, respectively, while the mean value for dung was 3.9%. The type of supplement did not affect CH 4 emissions, and the mean dung emission factor was 0.12 kg CH 4 head -1 year -1 . In summary, the supplementation of beef cattle in pastures with RUP did not mitigate NH 3 , N 2 O, and CH 4 emissions from excreta. The excreta emission factors for the GHGs measured, regardless of differences in the type of excreta, type of supplement, and period, were lower than the default value of Intergovernmental Panel on Climate Change revised guidelines. Further studies will be needed to fully understand the mechanisms underlying the effects of RUP on greenhouse gas emissions.
