“…For each dairy farm, we computed the annual surplus of nitrogen (N) and phosphate (P 2 O 5 ) using input-output accounting at farm level. This surplus is derived from the difference between farm inputs and farm outputs, with respect to N and P 2 O 5 , while the farm itself is considered a black box (Ondersteijn et al, 2002). Farm inputs of N and P 2 O 5 considered were: clover N-fixation, deposition, and import through roughage, concentrates, animals and manure.…”

“…The P content in some protein supplements, especially in RSM, is high compared with the basal diet based on forages and grains (MTT, 2014). According to literature, N and P are routinely overfed to ruminants, which leads to nutrient surpluses (Jonker et al, 2002;Ondersteijn et al, 2002;Dou et al, 2003). Therefore, it is important to evaluate if protein supplements can be reduced or excluded from grass silage-based diets without compromising animal performance.…”

The objective of this meta-analysis was to develop empirical equations predicting growth responses of growing cattle to protein intake. Overall, the data set comprised 199 diets in 80 studies. The diets were mainly based on grass silage or grass silage partly or completely replaced by whole-crop silages or straw. The concentrate feeds consisted of cereal grains, fibrous by-products and protein supplements. The analyses were conducted both comprehensively for all studies and also separately for studies in which soybean meal (SBM; n = 71 diets/28 studies), fish meal (FM; 27/12) and rapeseed meal (RSM; 74/35) were used as a protein supplement. Increasing dietary CP concentration increased ( P < 0.01) BW gain (BWG), but the responses were quantitatively small (1.4 g per 1 g/kg dry matter (DM) increase in dietary CP concentration). The BWG responses were not different for bulls v. steers and heifers (1.4 v. 1.3 g per 1 g/kg DM increase in dietary CP concentration) and for dairy v. beef breeds (1.2 v. 1.7 g per 1 g/kg, respectively). The effect of increased CP concentration declined ( P < 0.01) with increasing mean BW of the animals and with improved BWG of the control animals (the lowest CP diet in each study). The BWG responses to protein supplementation were not related to the CP concentration in the control diet. The BWG responses increased ( P < 0.05) with increased ammonia N concentration in silage N and declined marginally ( P > 0.10) with increasing proportion of concentrate in the diet. All protein supplements had a significant effect on BWG, but the effects were greater for RSM ( P < 0.01) and FM ( P < 0.05) than for SBM. Increasing dietary CP concentration improved ( P < 0.01) feed efficiency when expressed as BWG/kg DM intake, but decreased markedly when expressed as BWG/kg CP intake. Assuming CP concentration of 170 g/kg BW marginal efficiency of the utilisation of incremental CP intake was only 0.05. Increasing dietary CP concentration had no effects on carcass weight, dressing proportion or conformation score, but it increased ( P < 0.01) fat score. Owing to limited production responses, higher prices of protein supplements compared with cereal grains and possible increases the N and P emissions, there is generally no benefit from using protein supplementation for growing cattle fed grass silage-based diets, provided that the supply of rumen-degradable protein is not limiting digestion in the rumen.

“…Losses during animal feeding were included in the manure production. According to Ondersteijn et al (2002) and Børsting et al (2003), a nutrient use efficiency coefficient (NUE) was calculated to evaluate the efficient conversion of total inputs into products sold (meat, dairy products and cash crops), as follows:…”

A traditional dairy production system is still common today in the mountain environment of the Italian Alps, enhancing the economic valorisation of milk through the production of quality cheese such as Fontina PDO (Protected Designation of Origin), and favouring the agroenvironmental management of marginal areas. This type of dairy system depends mainly on summer grazing: farmers set up the farm stock on the basis of the high-altitude grassland areas available. For the rest of the year, the livestock is housed on the farm lowland, consequently reaching high stocking rates. Since grassland areas are limited in size here, animal feeding is largely based on acquired forages. In order to study the environmental sustainability of the lowland farm areas, agronomic management, nitrogen (N) and phosphorus (P) farm-gate balances were calculated for 22 livestock farms in the Valle d'Aosta region. Lowland surfaces show a quite high variability, with an average value of 6.8 ha. An unbalanced stocking rate referred to the lowland is common showing an average value of 5.7 livestock units (LU) ha -1 , but reaching a maximum of 26.8 LU ha -1 . Lowland milk production is approximately 1700 kg per LU per year, but some farms could reach 3500 kg per LU The feed efficiency varies from 1.1 to 4.7 kg milk per kg feed, depending on the farm feeding strategy. The average N farm-gate balance is equal to 75 kg N ha -1 . The two main input components are represented by purchased hay and feed, both showing the highest variability between farms. The output data also differ substantially among farms. The manure sold is the most important output component and represents 70% of the total output on average. The P farm gate balance surplus is equal to 6 kg ha -1 , but more than 25% of the farms considered show a negative value. The surpluses calculated in this work can be compared with the values belonging to a distribution calculated for bovine farms under different management and environmental conditions in Italy and Europe. They occupy the lower part of the distribution and are similar to those measured in mountains or other extensive environments.
