United Kingdom: £20 million for farming and forestry businesses
A new £20 million fund to help rural businesses increase profits and reduce their impact on the environment.
Dietary crude protein and phytase-xylanase supplementation of wheat grain based diets affect energy metabolism and enteric methane in growing finishing pigs
A combination of dietary crude protein and P reduction with added phytase is the key to optimize pig production efficiency, while minimizing their environmental impacts.
Effect of biofuel co-products in pig diets on the excretory patterns of N and C and on the subsequent ammonia and methane emissions from pig effluent
This study was conducted to investigate the effects of incorporation into pig diets of 20% of different co-products from the biofuel industries on animal growth performance, on N and carbon C excretions, and on the subsequent ammonia volatilisation and methane production during the storage of slurry.
Commission urges France and Greece to strengthen measures to combat water pollution by nitrates
In France, the current legal framework and the nitrates action plans for zones vulnerable to nitrate pollution do not effectively guarantee that this pollution is addressed effectively, as required by EU law. Greece too has a number of failings in this area.
Reduction of greenhouse gas emission from swine manure by using a low-protein diet with synthetic amino acids
Under ad libitum feeding, a low crude protein amino acid supplemented diet can reduce N excretion in manure with no impact on animal growth.
Computer simulation to find the best feeding strategy
Production of pig meat worldwide exceeds that of any other meat. Traditionally, linear programming is used to generate minimum cost diets that to meet the pig nutrient requirements. Of greater importance to the pig producer than least cost diets is the maximisation of gross margin (per pig place or per pig place per year).
United Kingdom - New research will help farmers reduce greenhouse gas emissions
Jim Paice, Minister of State for Agriculture, today announced funding of £12.6 million, from Defra and the Devolved Administrations, to improve our understanding of how UK agriculture contributes to climate change.
Farm practices survey and modelling to estimate monthly NH3 emissions from swine production in 12 Ecoregions of Canada
This paper describes a new model to estimate NH3 emissions from the swine sector, relying heavily on a recent survey of swine producers to determine the present N and manure management practices.
Spain - MARM presents ECOGAN
The Spanish Minister of Agriculture has presented the software ECOGAN, an application for the estimation of emissions and consumption of resources in farms.
USA - NIFA Air Quality Projects to help prevent and reduce greenhouse gas emissions
USDA’s National Institute of Food and Agriculture (NIFA) announced more than $5 million in grants to address air quality issues, including reducing agricultural atmospheric emissions and developing new mitigation practices.
UE - Nitrate pollution falling, but greater efforts still needed to meet water quality standards across the EU
The report shows that the implementation of legislation to prevent nitrates from agricultural sources polluting ground and surface waters is proving effective.
Water quality in pigs
Water is the most essential nutrient to livestock nutrition and must be considered as much as possible. It should be drinkable, it should not contain harmful substances and should be readily available for the animals concerned.
Influence of source and concentrations of dietary fibre on in vivo nitrogen excretion pathways in pigs as reflected by in vitro fermentation and nitrogen incorporation by faecal bacteria
The in vitro method may be a useful tool to predict the potential NH3 emissions of the different feed ingredients
Spain - The UdL develops a roboticized system to reduce costs and contaminating residues in swine herds
The research group of agriculture and precision livestock farming, agrotics and agrotechnology at the Universidad de Lleida (UdL), directed by Jesús Pomar, in collaboration with Agriculture and Agri-Food from Canada, has developed a roboticized system aimed at reducing costs and contaminating residues in swine herds.
Industry profits from pork CRC research
Australia’s pork industry is finally enjoying better times with rising pig prices, falling grain prices and a very welcome return to profitability, a situation that’s been enhanced by some vitally important research from the Pork Cooperative Research Centre (CRC).
