1. Produção e conforto térmico de bovinos da raça Nelore terminados em sistemas integrados de produção agropecuária
RESUMO O objetivo deste trabalho foi avaliar a pastagem, o desempenho, o conforto térmico e os parâmetros hematológicos de bovinos Nelore na fase de terminação em sistemas integrados de produção agropecuária com duas densidades de árvores (ILPF-1L= 196 árvores ha-1 e ILPF-3L=448 árvores ha-1) e em pleno sol (ILP). Foram avaliados a massa e a compo

2. O uso de sistemas agroflorestais diversificados na restauração florestal na Mata Atlântica
Resumo Com a nova legislação ambiental brasileira vislumbra-se a possibilidade do uso de sistemas agroflorestais diversificados para recompor áreas de preservação permanente e reserva legal, principalmente em pequenas propriedades rurais. Uma pergunta que surge, diz respeito à capacidade desses sistemas em reduzir custos na restauração florestal e, a

3. PRODUCTIVITY AND NUTRITIVE VALUE OF TIFTON 85 IN SUMMER, WITH AND WITHOUT IRRIGATION UNDER DIFFERENT NITROGEN DOSES
ABSTRACT The pasture irrigation has expanded, mostly in small areas in order to boost the production system, along with the use of soil improvement techniques and high-productivity grasses. Thus, this study, carried out on a small dairy farm property, aimed to evaluate the productivity, botanical composition and nutritive value of Tifton 85 with different ni

4. Soil Properties and Plant Biomass Production in Natural Rangeland Management Systems
ABSTRACT Improper management of rangelands can cause land degradation and reduce the economic efficiency of livestock activity. The aim of this study was to evaluate soil properties and quantify plant biomass production in four natural rangeland management systems in the Santa Catarina Plateau (Planalto Catarinense) of Brazil. The treatments, which included

5. Salinomycin and virginiamycin for lactating cows supplemented on pasture
Animals on pasture generally show higher feed efficiency as a result of the use of antibiotics. This study evaluated the effect of the antimicrobials salinomycin and/or virginiamycin on production and the ruminal parameters of supplemented dairy cows grazing on Panicum maximum cv. Tanzania. Twelve Holstein/Zebu multiparous cows were used, distributed in thre

6. Influência da estrutura da vegetação de um fragmento florestal nas características físicas e químicas da água e no funcionamento do ecossistema de um córrego rural
Riparian ecosystems are being rapidly degraded due to deforestation for conversion of natural areas to agriculture, pasture, and urban development. In rural areas, riparian forest remnants can be very important for biodiversity conservation and for the maintenance and improvement of water physical and chemical characteristics as the deforested stream passes

7. Simulated multipolarized MAPSAR images to distinguish agricultural crops
Many researchers have shown the potential of Synthetic Aperture Radar (SAR) images for agricultural applications, particularly for monitoring regions with limitations in terms of acquiring cloud free optical images. Recently, Brazil and Germany began a feasibility study on the construction of an orbital L-band SAR sensor referred to as MAPSAR (Multi-Applicat

8. Santa Inês sheep supplementation on urochloa grass pasture during the dry season: intake, nutrient digestibility and performance
This study was conducted with the objective of evaluating the effect of concentrate supplementation, formulated with different ingredients (Mesquite pod meal, sorghum meal or wheat meal and mineral supplementation) on performance, intake and digestibility of nutrients in Santa Inês lambs grazing on urochloa grass during the dry season. Twenty-four uncastrat

9. Production performance of lactating dairy cows at pasture fed concentrate supplemented with licuri oil
The objective of this study was to determine the optimal level of licuri oil to use in the concentrate of lactating dairy cows on pasture, through growth performance, feed conversion and cost of the supplementation. A total of 16 dairy cows, Holstein × Zebu crossbreed, were kept on Tanzania grass pasture. Cows were divided into four Latin squares, 4 × 4, f

10. Introdução de Stylosanthes guianensis Cv. mineirão em pastagem de Brachiaria ruziziensis: Influência na produção animal e vegetal.
A introdução de leguminosas em pastagens de gramíneas, na forma de consórcio, tem sido apresentada como uma estratégia para repor as quantidades de N que se tornam indisponíveis para as gramíneas ao longo dos anos. O efeito positivo desta prática para o ganho de produção animal é conhecido porém, ainda são escassos os resultados que demonstrem q

11. Manejo da micorriza arbuscular em sistemas integrados de lavoura e pastagens no Cerrado.
ABSTRACT: The arbuscular mycorrhizal fungi community is low in Cerrado soils and it gradually increases with soil cropping. Rotations of crops and of production systems stimulate propagation of those fungi in the soil, mycorrhiza formation and its effects in the plants. The crop-pasture integrated systems are well recommended, as pastures favors spores multi

12. Joining Time and Stocking Rate on the Production of Corriedale and Romney Sheep Lambing on Winter Improved Pasture in Southern Brazil.
Wool weight, fleece components and reproductive performance of Corriedale and Romney sheep joined within three periods (14 january-25 february, 01 march-12 april and 15 april-27 may) and stocked at two rates (10 ewes/ha and 15 ewes/ha) on paddocks of winter improved pasture (Trifolium repens and Lolium multiflorum) up to weaning, were examined during 5 years
