“…Many low input, predominantly non-irrigated livestock systems have little impact on freshwater resources from consumable water use [73]. Due to the higher proportion of concentrate in the diet, the total water consumption per hectare and per kg of beef body weight by animals is higher for GS consistent with prior research [32,74]. Our simulated water use for pasture improvements was higher per kg of beef body weight (BW) compared to extensive, but was lower per hectare in the Cerrado (−13%) and Amazon (−5%) biomes (Supplementary Materials, Table S4).…”

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.

“…Varios autores han relacionado el efecto positivo de reducir la frecuencia de suplementación sobre los costos operativos en sistemas de producción de carne, como una consecuencia directa del menor gasto en mano de obra, combustible, horas de trabajo en máquina, entre otros (de-Paula et al, 2010;de-Figueiredo et al, 2015;Bonadimann et al, 2017). En el presente trabajo no se registró una ventaja comparativa entre las frecuencias de suplementación y el tratamiento sin suplementación, probablemente motivado por la poca respuesta biológica en ganancia de peso asociada a las dietas, las cuales no lograron compensar el costo incremental en el suministro del alimento y a la calidad nutricional de las pasturas evaluadas.…”

Introducción. La producción de carne bovina se ve afectada por la estacionalidad forrajera y el costo de alimentación. La evaluación de diferentes frecuencias de alimentación en función de la pastura, podría sugerir una práctica apropiada para mejorar la rentabilidad. Objetivo. Evaluar técnica y económicamente la frecuencia de suplementación de novillos de ceba Brahman en pastoreo. Materiales y métodos. En el valle medio del Río Sinú, Colombia, se utilizaron 108 novillos distribuidos en un diseño de parcelas divididas en tres pasturas (Cynodon nlemfuensis, Megathyrsus maximus y Brachiaria hybrida, parcela principal) y tres esquemas de suplementación (subparcela): todos los días (STD), cada dos días (SDpM) y sin suplementación (SS). En el animal se evaluó la ganancia diaria de peso (GDP) y características morfométricas. En la canal: peso, rendimiento, longitud, perímetro de pierna, espesor de grasa e índice de compacidad. Los resultados biofísicos alimentaron la evaluación financiera de la tecnología implementada. Resultados. Hubo interacción entre la pastura y la frecuencia de suplementación (p<0,05) sobre la GDP. La mayor GDP se observó en animales de los tratamientos STD y en la gramínea C. nlemfuensis (680 g día-1), mientras que con la pastura de B. hybrida cv Mulato II en SDpM se encontró la menor GDP (500 g día-1). Hubo efecto (p<0,05) de la dieta en la longitud corporal (150 vs 152 cm para novillos no suplementados y suplementados, respectivamente). No hubo diferencias (p<0,05) entre tratamientos, sobre las características de la canal. Conclusiones. La respuesta biológica en GDP no compensó el costo operativo diferencial en animales suplementados. Es necesario evaluar nuevas dietas con materias primas y niveles de inclusión que contribuyan al aumento de la producción animal, para generar una respuesta diferencial del beneficio técnico y económico de la tecnología.

“…Reducing the frequency of supplementation can reduce labor and transportation costs, with potential for increased profits (DREWNOSKI; POORE, 2012). Bonadimann et al (2017) found that the supplementation concentrated in three times a week did not affect the performance of animals but led to a reduction in the distribution of labor costs necessary to provide concentrated supplement during the rainy season.…”

With the objective to evaluate different frequencies of supplementation on the performance and ingestive behavior of Nellore calves kept on Urochloa brizantha cv. Marandu pasture, 56 animals with initial average body weight (BW) of 174.5 kg were submitted to the following treatments: no supplement and 1x, 3x, and 7x supplementation per week. The supplement was provided in the amount of 3.5 g kg-1 of BW day-1. BW and evaluation of behavior were assessed every 28 days. The randomized block's design with two repetitions was used. The analyses of variance were carried out by the GLM procedure in the SAS software, and the means were compared by the Tukey’s test at 5% significance. The supplementation increased the average daily gain (ADG; P ? 0.05); however, it did not differ between frequencies (0.005, 0.190, 0.183, and 0.177 kg head-1 day for the no supplement treatment and 1x, 3x, and 7x per week, respectively). The animals in the no supplement treatment showed longer grazing time (P ? 0.05) compared to those receiving the supplement. However, results did not differ between frequencies (10.44, 8.57, 8.32, and 8.59 hours day-1 for no supplement treatments and 1x, 3x, and 7x per week, respectively). Thus, the frequency of supplementation can be reduced to once a week without reducing animal performance.
