Integrated crop–livestock systems (ICLS) have sustainably intensified modern agricultural practices worldwide. This research assessed how production and crop types impact the chemical properties of an Oxisol in Brazilian Cerrado, grain yield corn intercropped with palisade grass (Urochloa) off-season ICLS, (GY) soybean succession. Intercropped monocropped were a three-year field experiment: + Urochloa ruziziensis–soybean; U. brizantha cv. Piatã–soybean; Paiaguás–soybean (ICL–Paiaguás);...
The adoption of integrated production systems may be an alternative for improving soil health and increasing production. aim this study was to evaluate changes in fertility microbial metabolism, as well the impact on soybean productivity, different conservation contrast conventional system, after four years adopting systems. experimental design used a randomized block with seven treatments three replications. included species forage grasses, no-tillage soybean–maize system succession,...

Resumo O objetivo deste trabalho foi avaliar a produção de forragem capim-marandu (Urochloa brizantha) e os atributos químicos físicos do solo, em sistemas integrados produção. Foram avaliados integração lavoura-pecuária lavoura-pecuária-floresta, linhas simples (200 árvores por hectare) triplas (500 hectare), além plantio exclusivo eucalipto. A resistência mecânica à penetração solo não diferiram entre sistemas. infiltração água no menor nos agrossilvipastoris. Após dois anos da implantação...
Food production in sandy soils has evolved significantly, most notably through the advent of integrated crop–livestock systems (ICLSs). ICLSs increase soil cover, which maintains moisture and sequesters carbon (C). Here we investigate influence on physical, chemical, biochemical properties, grain yield (GY) tropical short-time. We compared seven two consecutive crops seasons (with soybean or maize as cash crops) southeastern Brazil. These were (1) corn + Urochloa brizantha cv. BRS...
Interest in improving feed efficiency of cattle has been increasing. The residual intake (RFI), the most commonly used measurement efficiency, is expensive and can only be a small number animals. Kleiber Index also proposed to measure RFI. In this study, we estimated genetic parameters for average daily weight gain adjusted weights obtain more comprehensive understanding potential responses selection support development breeding strategies. Genetic analyses were conducted on animal records...
ABSTRACT The objective this paper was to evaluate the effect of two categories beef finished in pasture with supplementation herbage allowance on performance, carcass and meat characteristics. Thirty-six Guzera cattle were used, 18 steers heifers an initial age 20 months. There significant difference daily weight gain for animal category allowance, which higher males animals submitted high allowance. Steers showed final weight, forequarter yield compared heifers, although hindquarter however...
RESUMO O objetivo deste trabalho foi avaliar a pastagem, o desempenho, conforto térmico e os parâmetros hematológicos de bovinos Nelore na fase terminação em sistemas integrados produção agropecuária com duas densidades árvores (ILPF-1L= 196 ha-1 ILPF-3L=448 ha-1) pleno sol (ILP). Foram avaliados massa composição morfológica da forragem, ganho médio diário, peso por área taxa lotação no verão outono, bem como as variáveis climáticas dos três horários animais (n=60). A forragem superior...
We evaluated animal production on black oats (Avena strigosa Schreb.) and italian ryegrass (Lolium multiflorum) pasture submitted to nitrogen top fertilization of 0; 150 300 kg ha-1, in the form urea. used 36 calves with average age weight 10.5 months 180 kg, respectively, as test-animals. The grazing system was continuous variable stocking rate. block design completely randomized three replicates (paddock). Average gain similar for levels (0.925; 0.969 1.045 day-1, respectively). Stocking...
The present study aimed to assess the productive performance, ingestive behavior, and thermal condition of crossbred beef heifers in an integrated livestock-forest (ILF) system with different tree-planting designs. Seventy-two ½ Angus Nellore were divided three treatments—conventional (CS) without eucalyptus, livestock 187 eucalyptus ha−1 (ILF-1L), 446 (ILF-3L)—, winter summer. Total dry mass forage (TDM), chemical analysis Marandu palisadegrass, average daily gain [...]
The objective of this study was to characterize the displacement patterns Nellore cattle in areas crop livestock and forest integration systems with density 196 448 eucalyptus ha-1. Paddock maps were drawn from satellite images experimental area. In each evaluated system there one trained observer, that on paddock map recorded place animals stayed every 10 minutes. exploration area by observed for 12 hours, starting at 6 a.m. ending p.m. ILP during evaluation bigger than ILPFs systems,...

Corn and grass intercropping is an interesting practice, forage plants belonging to the genus Urochloa are most commonly used in these situations. These show excellent adaptation low-fertility soil, easy establishment, considerable biomass production, as well being important competitor with weeds. In agrosilvopastoral systems, yield of corn crops grown together trees hindered due reduced radiation incidence caused by tree shading. This study aimed evaluate growth, light interception,...
