“…Grazing with water buffalo is really significant because selective grazing affects the structure and the dynamics of plant communities [67,71,72] which can be important for economic aspect too. It is well confirmed in the literature that buffalo can consume woody plants [73] and the Solidago species, which is rich in saponin [46] because the slow passage of food from the digestive system of buffaloes [58] makes them capable to consume low quality forage that is high in fiber [74][75][76][77]. Hence, based on the current investigation, water buffaloes really do not eat so selectively [60].…”

In nature conservation today, there is a global problem with the aggressive expansion of invasive plant species and the conservation of valuable grassland vegetation. Based on this, the following question has been formed: Is the domestic water buffalo (Bubalus bubalis) appropriate for managing various habitat types? How does grazing by water buffalo (Bubalus bubalis) affect on grassland vegetation? This study was carried out in four areas of Hungary. One of the sample areas was in the Mátra Mountains, on dry grassland areas where grazing had been applied for two, four and six years. The other sample areas were in the Zámolyi Basin, where wet fens with a high risk of Solidago gigantea and in a typic Pannonian dry grassland were investigated. In all areas, grazing was carried out with domestic water buffalo (Bubalus bubalis). During the study, we carried out a coenological survey, examining the change of cover of plant species, their feed values and the biomass of the grassland. According to the results, both the number and cover of economically important grasses (from 28% to 34.6%) and legumes (from 3.4% to 25.4%) increased in Mátra as well as the high proportion of shrubs (from 41.8% to 4.4%) shifted toward grassland species. In the areas of the Zámolyi Basin, invasive Solidago has been suppressed completely, the pasture has been converted completely (from 16% to 1%) and the dominant species has become Sesleria uliginosa. Thus, we have found that grazing with buffalo is suitable as a habitat management method in both dry grasslands and wet grasslands. Therefore, in addition to its effectiveness in the control of Solidago gigantea, grazing with buffalo is successful in both nature conservation and economic aspects of grassland vegetation.

“…Therefore, different approaches such as nitrogen balance and default factors have been attempted to estimate nitrogen excretion. Although IPCC [32] shows criteria useful to assess nitrogen excretion, as indicated, the approach suggested by Patra et al [38] to estimate the nitrogen excretion (urinary and fecal) in buffaloes was adopted, as did Romano et al [8].…”

“…Patra et al [38] stated that, in lactating animals, no models containing milk yield as a predictor were reliable for predicting NE, probably due to poor number of studies included in the dataset. In agreement with these authors, we adopted the same model for both lactating and dry cows.…”

Role of Corn Silage in the Sustainability of Dairy Buffalo Systems and New Perspective of Allocation Criterion

et al. 2022

This paper aims to compare the cradle-to-farm gate sustainability of two dairy buffalo systems, according to life cycle assessment guidelines (LCA). Primary data were obtained by five intensive farms with feeding plans based on non-corn silage (NCS) and five with corn silage (CS) based rations. Both systems were characterized by the presence of two farms with wheat grain yields, sold for human consumption. All the farms were in Southern Italy and seven were included in the Protected Designation of Origin (PDO) area of “Mozzarella di bufala campana”. The functional unit (FU) adopted was 1 kg of normalized buffalo milk (NBM); impact categories investigated were: global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), agricultural land occupation (ALO), water depletion (WD). Two different economic allocation procedures were tested: a first step aimed to mitigate the environmental impacts sharing among wheat grain, where present, and milk. The second stage involved culled buffalo cows. Neither the allocation nor the combination of allocation and feeding system showed significant effects (p > 0.05). Corn silage-based system (CS) showed lower impacts than non-corn silage (NCS) one for AP and EP (p = 0.002 and p = 0.051 respectively). High average dry matter yield per hectare of corn silage probably had a positive effect on SO2 and PO43− equivalents.

“…Although the IPCC guidelines indicate some criteria useful to assess nitrogen excretion, we followed the approach reported by Romano et al [7] because some studies showed that buffaloes have a greater efficiency of N utilization compared with cattle [19,20]. Consequently, we adopted the equations suggested by Patra et al [21] aimed to estimate the nitrogen excretion (urinary and fecal) in buffaloes. The N intake was counted by knowing the crude protein amount distinguished by livestock categories and farms.…”

Dairy Buffalo Life Cycle Assessment (LCA) Affected by a Management Choice: The Production of Wheat Crop

et al. 2021

View full text Add to dashboard Cite

Life cycle assessment (LCA) was performed in dairy buffalo farms representative of Southern Italian farming systems, similar due to several characteristics, with the exception of wheat production. This work evaluated the impacts derived from this management choice, comparing farms with wheat crop (WWC) or not (NWC). In agreement with the literature, economic allocation was chosen as a useful strategy to attribute equivalents to by-products, i.e., culled animals; the same criterion was also adopted to assign pollutants to wheat grain, limited to WWC farms. Environmental impacts in terms of Global Warming Potential (GWP, kg CO2 eq), Acidification Potential (AC, g SO2 eq), Eutrophication Potential (EU, g PO43-eq), Agricultural Land Occupation (ALO, m2y) and Water Depletion (WD, m3) were estimated. The production of wheat crop significantly affected (p < 0.05) the Agricultural Land Occupation (ALO) category as WWC farms need adequate land. WWC farms could allow a significant reduction in eutrophication (EU) compared to NWC farms (p < 0.05).
