Abstract
CONTEXT
Integrated crop-livestock systems are facing the pressure to intensify worldwide, yet decoupling crops and livestock can lead to specialized systems relying on greater external inputs and potential negative externalities.
OBJECTIVE
Our goal was to compare rice-pasture, as the business-as-usual rotation, with two intensified systems, rice-soybean and rice-cover crop, to address the following objectives: 1) quantify partial carbon footprint (CF) including both crop and livestock, 2) develop a multi-criteria performance index based on productivity, economic, and environmental indicators at the systems-level, and 3) evaluate the stability of this index over the study period.
METHODS
To understand how increasing the frequency of annual grain crops influences whole-system sustainability, we evaluated 10 productivity, economic and environmental indicators as well as a multi-criteria performance index and its stability in three rice-based rotation systems over 7 years in Uruguay. Treatments were: (a) rice?pasture [a 5 yr rotation of rice?ryegrass (Lolium multiflorum Lam.)?rice, then 3.5 yr of a perennial mixture of tall fescue (Festuca arundinacea Schreb.), white clover (Trifolium repens L.), and birdsfoot trefoil (Lotus corniculatus L.)], (b) rice?soybean [a 2-yr rotation of rice?ryegrass?soybean (Glycine max [L.] Merr.)? Egyptian clover (Trifolium alexandrinum L.)], and (c) rice?cover crop (an annual rotation of rice?Egyptian clover).
RESULTS AND CONCLUSIONS
Rice-soybean had medium productivity and energy use, resulting in the highest nitrogen and energy use efficiency and among the lowest yield-scaled C footprint. Field greenhouse gas emissions and embodied energy in fuel and agrochemicals were similar in rice-pasture and rice-soybean, but the increase in soil organic carbon in pasture rotating with rice was able to offset this by almost 50%. Rice-cover crop had the highest economic incomes but also the highest input costs, translating into the lowest gross margin. Although the rice-soybean and rice-pasture had a similar gross margin, the variability in rice-pasture was lower and with lower input costs. Rice-soybean and rice-pasture had a multi-criteria performance index 65% higher than rice-cover crop (0.35). Rice-pasture had the highest overall stability across four different stability parameters calculated. We conclude that the intensification of rice-pasture with annual crops could reduce the stability of sustainability without increasing economic performance, even for rice-soybean that showed the best the multi-criteria performance but with less stability across indicators.
SIGNIFICANCE
The findings of this study demonstrate how the integration of rice and pastures with livestock achieves the best combination of stability across profitability and environmental performance, thus mitigating vulnerability to external stressors. MenosAbstract

Abstract:
Eimeria bovis, Eimeria zuernii, Eimeria ellipsoidalis, Eimeria auburnensis, Eimeria canadensis and Eimeria alabamensis were identified on different dairy farms in Uruguay. The most prevalent species were E. bovis and E. zuernii, which were mainly found in the feces of calves with diarrhea. The dynamics of oocyst excretion were evaluated via the weekly determination of oocysts per gram (OPG) values in fecal samples from 97 calves over seven months. Three groups of calves were formed according to their age in days: Group 1 (1?20 days old), Group 2 (21?40 days old) and Group 3 (41?65 days old). In Group 1, the median OPG was zero, and the maximum OPG was 1,680. In Group 2, the median OPG was between zero and 8,240, and the maximum OPG was 428,800. In Group 3, the median OPG was between zero and 220, and the maximum OPG was 16,000. For the evaluation of the relationship between OPG and age group, a proportional odds model was built. Two samples from 60 bovines evaluated in Group 2 and in Group 3 were selected. OPG was categorized as negative, moderate (lower than or equal to 4,000) or high (greater than 4,000). Calves of Group 2 (21?40 days old) were significantly (p < 0.001) more affected by eimeriosis than calves of Group 3 (41?65 days old). Considering that diarrhea in calves is a multifactorial disease, eimeriosis should be considered when evaluating the control measures for diarrhea syndrome, particularly in calves of 21?40 days of age. |
