“…In our study, the cows remained longer in the shaded (70%) than sunny areas. Shaded areas present better microclimatic conditions and cows remain longer in these areas during the summer (Deniz et al ., 2020), even on days with relatively low levels of solar radiation (Schütz et al ., 2010). In the winter, cows could also use shade when motivated to do so, either to seek protection from the sun in the middle of the day or to rest (de Sousa et al ., 2021).…”

The aim of this Research Communication was to apply the data mining technique to classify which environmental factors have the potential to motivate dairy cows to access natural shade. We defined two different areas at the silvopastoral system: shaded and sunny. Environmental factors and the frequency that dairy cows used each area were measured during four days, for 8 h each day. The shaded areas were the most used by dairy cows and presented the lowest mean values of all environmental factors. Solar radiation was the environmental factor with most potential to classify the dairy cow's decision to access shaded areas. Data mining is a machine learning technique with great potential to characterize the influence of the thermal environment in the cows' decision at the pasture.

“…Crop-Livestock-Forest and agroforestry integration systems were identified as one of the technologies to be adopted among the measures proposed in the PLANO ABC (BRASIL, 2012), as they provide combined benefits such as water regulation (SONE et al, 2019), favorable microclimate (DENIZ et al, 2020;CASTILLO et al, 2020), biodiversity (FIALHO et al, 2021) and carbon stock (MORALES et al, 2020;NATH et al, 2021), contributing to providing environmental services and greater resilience to climate change (MURGUEITIO et al, 2011;LANDHOLM et al, 2019). Studies aimed at this research area were intensified and boosted by these public policies that invest in innovative technologies of a sustainable nature.…”

Produção de conhecimento em sistemas de integração lavoura pecuária floresta: uma análise cienciométrica

et al. 2021

View full text Add to dashboard Cite

A cienciometria estuda, através de indicadores quantitativos, uma disciplina específica da ciência. Sistemas integrados de produção são uma área do conhecimento científico voltadas para o desenvolvimento da produção rural sustentável. Estes sistemas demandam um planejamento adequado e minucioso dos componentes agrícolas florestais e pecuários, para assim, proteger adequadamente os recursos naturais. Estudos cienciométricos auxiliam na análise quantitativa destes estudos e geram instrumentos mais precisos para adoção de políticas públicas e científicas. O objetivo do presente trabalho foi fazer uma análise cienciométrica da produção de conhecimento para sistemas de integração Lavoura Pecuária Floresta, a nível mundial, de forma a identificar os (a) os autores mais produtivos (b) a evolução histórica do número de publicações e os periódicos que mais publicam em relação ao tema (c) os países que mais produzem conhecimento científico sobre o tema e (d) as principais abordagens que cobrem o tema. Foram recuperados 1592 estudos do banco de dados Web of Science e Scopus compreendendo o período de 1983 a agosto de 2020. O Brasil foi o país com o maior número de publicações sobre sistemas de integração lavoura pecuária floresta. A maioria dos artigos foram caracterizados na área de conhecimento sustentabilidade, biodiversidade e conservação. Nossos resultados indicam que os esforços científicos têm sido destinados aos estudos referentes a práticas sustentáveis de produção e os sistemas integrados vem sido apontado como um potencial sistema de produção que atende as demandas atuais de desenvolvimento sustentável principalmente nos países tropicais em desenvolvimento.

“…As a result, the silvopastoral system (SPS) has been adopted as an alternative to improve the thermal environment of farms (Deniz et al , 2019; Pezzopane et al , 2019). When raised in an SPS, animals have the opportunity to access different areas of the paddock, remaining in the sun on cold days (de Sousa et al , 2021a) or seeking shade on hot days (Deniz et al , 2020). This opportunity to choose the most comfortable location can change the dynamics of the deposition of faeces in the pasture, since shaded areas are variable throughout the day; this means that some faecal pads will remain exposed to solar radiation for longer than others.…”

The objective of this study was to evaluate the predatory activity of the nematophagous fungus Duddingtonia flagrans on infective larvae of gastrointestinal nematodes from dairy heifers in different conditions (shaded and sunny) of a silvopastoral system (SPS) on an agroecological farm. Ten Jersey heifers were divided into two groups: treated (received pellets containing fungus); and control (received pellets without fungus). Twelve hours after fungus administration, faeces samples were collected for in vitro efficacy tests. The animals then remained for 8 h in the experimental pasture area. At the end of this period, 20 faecal pads (10 treated and 10 control) were selected. Pasture, faecal pad and soil collections occurred at intervals of seven days (d), totalling four assessments over 28 d. To evaluate the influence of the conditions shaded and sunny, we registered the condition of the location of each faecal pad per hour. After 12 h of gastrointestinal transit in dairy heifers, a reduction of 65% was obtained through the in vitro test. The treated group presented a lower number of infective larvae (L3) in the faecal pad and upper pasture. Differences in numbers of L3 were observed between the conditions (sunny and shaded) in the faecal pad of the control group; while in the treated group there were no differences between the conditions. The predatory activity of the fungus was efficient over time in the shaded and sunny conditions of an SPS, decreasing the parasite contamination during the pasture recovery time in a subtropical climate.
