“…Our results were consistent with prior research [32], where, compared with the extensive system, pasture systems using intensification strategies had higher costs, but beef production almost doubled with combined intensification techniques including pasture fertilization [32]. Our modeled strategies had higher production costs, but meat production and profitability were also higher than extensive, as system intensification is required to achieve higher slaughter weight and carcass yield which dilutes costs per kg of beef [46].…”

Economic development, international food and feed demand, and government policies have converted Brazil’s natural ecosystems into agricultural land. The Integrated Farm System Model (IFSM) was evaluated using production, economic, and weather data collected on two cooperating farms in the Legal Amazon and Cerrado biomes in the Midwest state of Mato Grosso, Brazil. Three sustainable agricultural intensification strategies, namely grain supplementation, pasture re-seeding, and pasture fertilization were simulated in IFSM with double the beef cattle stocking density compared to extensive grazing. Livestock dry matter consumption simulated in IFSM was similar for pasture grazing estimates and actual feed consumed by beef cattle on the two collaborating farms. Grain supplementation best balanced beef production and profitability with lower carbon footprint compared to extensive grazing, followed by pasture fertilization and pasture re-seeding. However, pasture re-seeding and fertilization had greater use of water and energy and more nitrogen losses. Human edible livestock feed use was greatest for grain supplementation compared to other modeled systems. While grain supplementation appears more favorable economically and environmentally, greater use of human edible livestock feed may compete with future human food needs. Pasture intensification had greater human edible feed conversion efficiency, but its greater natural resource use may be challenging.

“…The water holding capacity (WHC) of meat may be influenced by the rate and extent of pH descends (Oliveira et al 2018). In the present study, the type of diets did not affect the WHC of beef muscle, possibly due to a lack of significant differences in the final pH of the meat.…”

Carcass parameters, meat quality, fatty acid profile, and amino acid composition of Simmental bulls fed a diet based on various forage silages (VS) compared with the one based on only corn silage (CS) were investigated. A total of thirty male Simmental (440.5 ± 11.5 kg) was selected and assigned randomly divided into two treatments. All animals were fed twice daily (0700 and 1700 h) and water was supplied ad libitum, feed considering 5 to 10% refusals. The period of 207 days fattening trial was divided into three stages as P1 (1 to 64 days), P2 (65 to 130 days), P3 (131 to 207 days). Six beef cattle were slaughtered from each group at the end of the experiment. Substituting CS with VS in the finishing diet did not have a significant effect on slaughter performance, nutrient content, fatty acids, and amino acids profile (P > 0.05). However, the intramuscular fat and connective tissue content of the VS diet was lower compared with the CS diet (P < 0.05). Also, beef cattle fed VS diet could improve eye muscle area, increase histidine content and diameter of muscle fiber. In conclusion, substituting corn silage with various forage silages in the diet of beef cattle could potentially reduce the negative effect under the studied conditions. © 2021 Friends Science Publishers

“…The stocking rate increases due to the intensification of the beef cattle production system, with a consequent increase in LW gain and carcass production per hectare (Cardoso et al, 2016). The IHS system resulted in 1.6-, 2.1-, and 6.5-fold higher production of kilograms carcass compared with the DHS, DMS, and DP systems, respectively (Oliveira et al, 2018). Management strategies that improve FE or productivity by using better forage and high-yield animals can reduce CH 4 emissions per unit of product (Patra, 2012;Oliveira Silva et al, 2017).…”

Increasing greenhouse gas emissions from anthropogenic activities have contributed to global warming and consequently, to climate change. Among all sources of emissions, the agricultural sector accounts for just under a quarter, mainly because of the intensification of food production systems necessary to supply the growing demand of the population. As ruminal fermentation is the largest source of methane emission in the livestock industry, emission by cattle has become the focus of studies. The aim of this study was to evaluate enteric methane emission and emission intensities of Nellore cattle at different ages submitted to levels of intensification of the grazing system. Twenty-four animals per cycle (age of 21.8 and 13.1 months in cycles 1 and 2, respectively) were randomly distributed across different grazing systems: irrigated pasture with a high stocking rate (IHS), dry land pasture with a high stocking rate (DHS), recovering dry land pasture with a moderate stocking rate (DMS), and degraded pasture (DP). Methane emission was measured using the sulfur hexafluoride technique in each season of the cycle. Intensive systems provided higher yields of good-quality forage, as well as superior animal performance when compared to DP. Methane yields were different between seasons and cycles. CH4 emissions per average daily weight gain and dry matter digestible intake were difference between treatments. Differences in the results were observed when they were analyzed per hectare, with the highest gain yield (P = 0.0134), stocking rate, weight gain, carcass production, and total methane emission (P < 0.0001) being found for the intensive systems. There were no differences in emissions per weight gain or carcass production between production systems, while a difference was observed between cycles (P = 0.0189 and P = 0.0255, respectively), resulting in lower emission intensities for younger animals. We conclude that more intensive systems resulted in a higher kg production of carcass per hectare; however, animals at 19 months of age raised in the IHS and DMS systems had a lower emission intensity in kg of CO2-eq. per kg of carcass. Moderate intensification (DMS) using animals at about 19 months of age might be an effective strategy to mitigate GHG emissions from Brazilian tropical pastures. Further studies are needed to understand the relationship between increasing productivity and decreasing environmental impacts, especially methane emission from ruminants.
