“…In addition, few studies explored soil surface temperature (n = 4) and solar radiation (n = 3). The incidence of solar radiation and, consequently, radiant thermal load varies as a function of tree arrangement and position, which can impact on soil surface temperature and consequently influence the lying behaviour of cattle (De-Sousa et al, 2021b). To reach a consensus on the positive and critical points of each tree arrangement, more research is needed; importantly, studies must give complete details of the characteristic of SPS.…”

“…However, during the summer, Carnevalli et al (2020) found the highest frequency of rumination in the moderate tree density. Ruminating generates heat, and usually, the peak of this behaviour occurs in the hottest hours of the day, indicating that it is more comfortable to perform it in the shade (Deniz et al, 2021b). De-Sousa et al (2021a) found that cows spent less time ruminating in the scattered tree arrangement than in the single row of trees on the border fence; in the arrangement of scattered trees, the cows spent more time performing other behaviours, which, according to the authors, may be related to grooming behaviour.…”

This review aimed to provide a critical and systematic evaluation of the scientific literature about the effect of tree arrangements of the silvopasture system on the thermal environment, behaviour, and performance of cattle. We conducted a search using Web of Science and Google Scholar to identify the key literature of the theme. Peer-reviewed published articles written in English, comparing one or more tree arrangements of SPS to treeless pasture or comparing shaded and sunny areas within the SPS, were selected. The resulting manuscripts (n=191) underwent a four-step PRISMA appraisal process. This process resulted in a final sample of 37 articles, which were used for recording metadata, bibliometric analysis, and assessment of the results, using the software R. Of the 37 articles, 20 studies evaluated dairy cattle (behaviour: 14; performance: 7) and 17 evaluated beef cattle (behaviour: 6; performance: 12). The main behaviours evaluated were grazing (95%) and ruminating (90%), while weight gain (89%) was the main performance variable evaluated. The co-occurrence network analysis highlighted that the studies related the animals’ response to improving the thermal environment promoted by silvopasture systems. The main difference among tree arrangements evaluated by the studies was tree density, which ranged from 5 to 800 trees/ha; most studies covered SPS with row of trees (single row, n=16 and multiple rows, n=19). Most studies (n=32) were carried out in Brazil. The evidence of this review showed that regardless of tree arrangement, the silvopasture system improves the thermal environment for cattle, although some effects on behaviour and performance are inconclusive.

“…Trees in the pasture alter the local microclimate, as they reduce the radiant thermal load by promoting lower air temperatures and soil surface temperatures in shaded areas (de Sousa et al , 2021b). Thus, we hypothesized that the different conditions (shaded and sunny) of the SPS influence the effectiveness of D. flagrans .…”

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.
