Increased Foraging in Outdoor Organic Pig Production—Modeling Environmental Consequences
Consumers' motivations for buying organic products include a wish of acquiring healthy, environmentally friendly products from production systems that also ensure a high level of animal welfare. However, the current Danish organic pig production faces important challenges regarding environmental impact of the system. High ammonia emissions arise from outdoor concrete areas with growing pigs and...
متن کاملSurvival and transmission of Salmonella enterica serovar typhimurium in an outdoor organic pig farming environment.
It was investigated how organic rearing conditions influence the Salmonella enterica infection dynamics in pigs and whether Salmonella persists in the paddock environment. Pigs inoculated with S. enterica serovar Typhimurium were grouped with Salmonella-negative tracer pigs. Bacteriological and serological testing indicated that organic pigs were susceptible to Salmonella infections, as 26 of 4...
متن کاملTail-biting in outdoor pig production.
A study was performed in five identical outdoor production units in the same geographic area using growing-finishing pigs of similar genetic makeup, age, diet and feed management. The severity of tail-biting (TS) was scored 1-4. The average group prevalence of bitten tails at slaughter on different farms was between 14.1+/-2.1% and 20.1+/-3.0% (P<0.05). The odds of a barrow being bitten were 2....
متن کاملAmmonia Losses from Outdoor Pig Fattening at Two Swedish Organic Farms
Ammonia (NH3) emissions originate predominantly from manure. In outdoor pig production, excretory behaviour creates nitrogen (N) point loads. This study examined ammonia losses from pigs on grassland at two farms by calculating N field balances per pen and sub-areas preferred (P) and not preferred (NP) for excretion. Spatial variation in ammonia losses was measured with an equilibrium concentra...
متن کاملTraditional adventure activities in outdoor environmental education
Recently, the place of adventure activities in outdoor education has become contentious, particularly in Australia and the United Kingdom. It can be challenging for outdoor leaders to incorporate adventure activities with attempts to foster environmental awareness, understanding and action. Recently, some authors have suggested practitioners eliminate the tension by removing adventure activitie...
