The environmental impact of greenhouse gases caused by livestock farms plays a fundamental role due to the implications and environmental consequences that livestock practices entail, affecting the stability of the entire ecosystem connected to them, especially as a consequence of the growing demand for products of animal origin. The aim of this work was to quantify the CH4 emissions factor in lactating buffaloes by comparing four different types of livestock management: family, conventional, organic and sustainable. To determine the enteric CH4 emissions from buffalo, information about animal production and farm management was analyzed, and the CH4 emission factor was calculated using the IPCC Tier 2 model. ANOVA was conducted to evaluate significant differences between the farms; Pearson’s correlation was used to evaluate the relationship between parameters. In a conventional farm, the CH4 emission factor for buffalo was 27.69 kg CH4/head/yr compared to 22.77 and 21.61 kg CH4/head/yr respectively for organic and family-run. These data may also depend on the higher protein and fiber content in the administered unifeed. Furthermore, the ratio of enteric emissions factor of CH4 / gross energy intake ratio reflected these data (12.04 vs 10.93 vs 10.16 vs 10.65 for conventional, organic, sustainable, and family-run farms, respectively).

“…In general, the herd/date effect was the most important source of variation. An important factor differentiating the mineral contents of milk from different buffalo herds is probably feeding, as shown by studies on mineral supplementation (Shahzad et al, 2007;Begum et al, 2010;Neglia et al, 2014). Days in milk significantly affected all the traits examined, in particular K and Mg concentrations (P < 0.001).…”

The aims of this study were (1) to assess variability in the major mineral components of buffalo milk, (2) to estimate the effect of certain environmental sources of variation on the major minerals during lactation, and (3) to investigate the possibility of using Fourier-transform infrared (FTIR) spectroscopy as an indirect, noninvasive tool for routine prediction of the mineral content of buffalo milk. A total of 173 buffaloes reared in 5 herds were sampled once during the morning milking. Milk samples were analyzed for Ca, P, K, and Mg contents within 3h of sample collection using inductively coupled plasma optical emission spectrometry. A Milkoscan FT2 (Foss, Hillerød, Denmark) was used to acquire milk spectra over the spectral range from 5,000 to 900 wavenumber/cm. Prediction models were built using a partial least square approach, and cross-validation was used to assess the prediction accuracy of FTIR. Prediction models were validated using a 4-fold random cross-validation, thus dividing the calibration-test set in 4 folds, using one of them to check the results (prediction models) and the remaining 3 to develop the calibration models. Buffalo milk minerals averaged 162, 117, 86, and 14.4mg/dL of milk for Ca, P, K, and Mg, respectively. Herd and days in milk were the most important sources of variation in the traits investigated. Parity slightly affected only Ca content. Coefficients of determination of cross-validation between the FTIR-predicted and the measured values were 0.71, 0.70, and 0.72 for Ca, Mg, and P, respectively, whereas prediction accuracy was lower for K (0.55). Our findings reveal FTIR to be an unsuitable tool when milk mineral content needs to be predicted with high accuracy. Predictions may play a role as indicator traits in selective breeding (if the additive genetic correlation between FTIR predictions and measures of milk minerals is high enough) or in monitoring the milk of buffalo populations for dairy industry purposes.

“…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.…”

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

et al. 2021

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).
