“…The wilting leads to a decrease in moisture and the addition of inoculants affects the fermentation and reduces many negative effects of unacceptable fermentation (Wright et al, 2000). According to Borreani et al (2009), wilting is applied to reduce dry matter losses in the effluent and to lower the weight of water that has to be transported from the field to the silo.…”

ABSTRACT:The objectives of the study were to evaluate the effects of wilting and additives on the fermentation quality of field pea silage, and to determine the rumen degradability of organic matter of pea silage. The following additives were used: commercial bacterial inoculant (1 g/t) containing homofermentative lactic acid bacteria -Lactobacillus rhamnosus (NCIMB 30121) and Enterococcus faecium (NCIMB 30122) and chemical additive containing formic acid, propionic acid, ammonium formate and benzoic acid (4 l/t). Compared to the control and chemical additive, the addition of the inoculant to wilted silage increased the lactic acid content (P < 0.05) and lactic:acetic ratio (P < 0.001). Both bacterial and chemical additives decreased (P < 0.001) the pH value of wilted silage. Differences between the control and chemically treated unwilted silage were also significant (P < 0.01). The pH value of silage with chemical additive was lower compared to the control. Proteolysis determined in wilted silage was lower compared to unwilted silage. Rumen degradability of organic matter in wilted silage treated with the chemical additive was found to be higher (P < 0.05) than in control and inoculant treated silages.

“…The CV silage showed the highest values of pH, which is in agreement with PURSIAINEN & TUORI (2008); this result in both studies could reflect the low content of water-soluble carbohydrates of legume silage, which enhances clostridial fermentation and butyric acid production (BORREANI et al, 2009). The CV silage had the highest values of CP, which is a desirable nutritional component in rabbit nutrition; however, it should be taken into account that a higher protein content can be associated with higher rates of proteolysis in legume silage (CAVALLARIN et al, 2007).…”

Ensiling on chemical composition and in vitro fermentation in rabbits of different forages

The effect of chemical composition of silages on in vitro gas fermentation profiles in rabbits was examined. The study was performed using 7 silages: beans (Phaseolus vulgaris), faba bean (FB, Vicia faba), common vetch (CV, Vicia sativa), ryegrass (Lolium perenne), barley (B, Hordeum vulgare), barley with common vetch (BCV) and barley with faba bean (BFB). We used 3 New Zealand White (NZW) rabbits as donors of caecal content in each incubation run (n=3). Data were analyzed in a completely randomized experimental design. The CV silage showed higher values of crude protein (CP), followed by FB and bean silages (P<0.001). Barley silage had the lowest CP content (96g kg-1 DM) (P=0.001). The NDF and ADF content were lower (P<0.001) for beans and CV compared with the rest of the forage silages. Ryegrass silage had higher values of dry matter degradation, organic matter degradation, relative GP and SCFA (P<0.001). The highest values of digestible energy were for CV and bean silages (P<0.001). Ryegrass and CV silages showed higher levels in GP parameters, which could be associated with their better chemical composition characteristics, mainly protein and fiber content.

“…As climate causes differences in actual yield from year to year [30], we calculated annual average yield using provincial data on crop production from 2000 to 2008 (ISTAT, www.istat.it/ agricoltura/datiagri/coltivazioni.). As site-specific N content data are not available, we used average values commonly reported in the literature [31][32][33]. The variation in the crops' N content (mainly due to crop variety, climate, soil properties, and management) was assumed to be on the order of 25% [23].…”

A nitrogen mass balance, realized for the lower Oglio River basin (Po River Plain, northern Italy), suggested an elevated impact of agricultural activities in this watershed. Livestock manure, synthetic fertilizers, biological fixation, atmospheric deposition, and wastewater sludge contributed 51,34,12,2, and 1% of total N (TN) . About 34% of the N surplus was exported annually from the basin while the remaining amount (about 26 800 t N year À1) underwent other unaccounted for processes within the watershed.The relevance of nitrogen removal via denitrification in aquatic compartments within the watershed was evaluated. Denitrification in the secondary drainage network can represent a relevant nitrogen sink due to great linear extension (over 12 500 km), with estimated nitrogen loss up to 8500 t N year À1 . Denitrification in the riverbed and in perifluvial wetlands have the potential to remove only a small fraction of the nitrogen surplus (<3%). Evidence suggests the relevance of groundwater as a site of nitrogen accumulation. IntroductionIncreased reactive nitrogen (N) input to the biosphere by human activities has resulted in the gradual saturation of the N buffering capacity of terrestrial areas and augmented N loads toward surface and ground waters. Reactive N is now accumulating in the environment at all spatial scales, from local to global [1,2]. Farming activity is one of the primary causes for the current high N loads, as an unbalance between livestock manure production and agricultural lands for spreading causes an available N pool generally exceeding the crop requirements and the soil's metabolic capacity [3,4]. The control of N inputs to aquatic systems is of general public interest due to their known ecosystemic consequences, namely eutrophication [5][6][7] and the potential toxicity risks posed by a high nitrate (NO À 3 ) concentration in water resources [8,9]. Rivers are particularly critical because they link terrestrial and coastal ecosystems, and aggregate stressors occurring at the landscape scale. Human-driven alterations such as channelization, impoundment, water withdrawals, reduction of perifluvial vegetation, and wetlands have enhanced soil erosion and runoff processes, affected the biogeochemistry of riparian and in-stream zones and reduced the efficiency of the river network in mitigating N excess [10][11][12].Worldwide N budgets estimate that, on a long-term basis, up to $75% of the N load generated within catchments is generally retained within the basin and not exported via river discharge [2,13]. The ratio between exported and generated N can be considered an integrated measure of the watershed metabolic capacity toward N. The retained N is the result of several processes, among which some are well studied (i.e., crop uptake) while others are scarcely investigated (i.e., denitrification in lotic ecosystems, N storage in soils, and percolation to groundwater) and represent large unknown terms in N budgets [14]. Even if denitrification is accepted as the major sink of N excess in the...
