“…This may suggest that the animals’ gain was due to supplementation, with a possible substitutive effect. For Santos et al [ 43 ], supplement energy levels are a tool for pasture management, reducing forage consumption and increasing stocking rate.…”

The objective was to characterize the pastures by grazing cycle, as well as to evaluate the performance of buffaloes in intensive rotational grazing in a silvopastoral system in the eastern Amazon supplemented with agro-industry co-products in order to characterize the grazing cycles, the composition of the fractions, and the carcass yield. Fifteen non-castrated, crossbred water buffaloes (Murrah × Mediterranean) were used. All animals used in the study were clinically healthy and weighed approximately 458 kg. The animals were grazed in a single group, and supplementation (1% of live weight—LW/day) was divided into three treatments: control (control—conventional ingredients); Cocos nucifera coconut cake (Cocos nucifera) (coconut cake—70%); and palm kernel cake (Guinean elaeis) (palm kernel cake—70% palm kernel cake). The chemical composition of the forage is different in each part of the plant, with higher protein values in the leaves (11.40%) and higher acid detergent fiber (ADF) values in the stems (50.03%). Among the ingredients of the supplement, corn has the highest percentage of indigestible protein (35.57%), most of the protein in palm kernel cake is B3 (49.11%), and in Coco, B2 (51.52%). Mombasa grass has a higher percentage of B3 and B2 proteins; the indigestible fraction is lower in the leaves (17.16%). The leaf/stem ratio also varied between grazing cycles, being better in the second cycle (2.11%) and with an overall average of 1.71. Supplement consumption varied between cycles and was higher in the control treatment, with an overall mean of 4.74. There was no difference in daily weight gain and carcass yield, with an average of 1 kg/day and 49.23%, respectively. Therefore, it can be concluded that including supplements based on by-products from the coconut and palm oil agro-industries promotes performance and carcass yields compatible with conventional supplements. Their use reduces production costs, optimizes the utilization of forage mass, enhances the sustainability of the production chain, and, therefore, is recommended.

Sustainability Assessment of Intensification Levels of Brazilian Smallholder Integrated Dairy-Crop Production Systems: An Emergy and Economic-Based Decision Approach

et al. 2023

This study aimed to evaluate the sustainability of integrated dairy–crop production systems by employing emergy and economic theory perspectives, and to identify strategies to improve the intensification of dairy production systems. A case study of a small Brazilian dairy production system (PROP) was created to assess dairy herd feed exchanges as a sustainability pathway. Three scenarios were proposed for the examination of a dairy production system: extensive (EXT); semi-intensive (SIS); and intensive (INT). The Interlink Decision Making Index (IDMI) was used to compare sustainability among them. The PROP demonstrated higher environmental performance than the other scenarios (ESI = 1.30, 0.65, 0.95, and 0.71, for PROP, INT, SIS, and EXT, respectively); however, PROP’s profitability was 1.6 times lower than that of SIS and INT, although PROP’s profitability was higher than that of the EXT scenario. Notably, the IDMI identified the SIS scenario as having the best sustainability among those studied. We concluded that the consideration of the energy contribution for feed ingredients yields a more equitable evaluation of environmental performance in integrated dairy–crop production systems, which leads us to propose the following suggestions: (i) target higher profit performance by changing extensive dairy systems to semi-intensive systems that utilize feed ingredients produced at the farm, and (ii) promote higher environmental performance by transforming intensive dairy systems to semi-intensive systems that are directed more toward maintaining environmental factors. In our view, public policies should focus on bonifications that upgrade dairy systems to promote and utilize best practices for dairy–crop integration.
