Abstract:

The applied technology is an alternative approach to pigkeeping-systems. An outdoor pig production breeding sows are kept at pasture either year-round or in a certain period of the year. The important equipments of outdoor pig production are farrowing or grouping sows inhuts, which protect pigs against the effects of extreme weather, and electric fences, which surround and divide the pasture. Concentrate feed can be fed from the ground or from feeders which are made of steel or timber. One of main advantages of this pig keeping system is the total mobilizable keeping technology.Within the scop

This study examined the environmental impact of the three common organic pig husbandry systems, indoor (n = 24), partly outdoor (n = 30), and outdoor (n = 10), in eight European countries. Global warming (GWP), acidification (AP), and eutrophication potential (EP) was assessed per 1000 kg pig live weight on 64 farrow-to-finish pig production chains (cradle to farm gate). GWP, AP, and EP varied greatly, and the most important source was feed production, followed by housing.

Between 1890 and the present, the total number of pigs in the USA has remained at 50–60 million, but dramatic changes in swine husbandry over the course of the 20th century have metamorphosed pig production from small, extensive (outdoor), labor-dependent enterprises into large, intensive (indoor), capital-dependent, production systems.

AbstractThe EU regulation for organic pig production requires outdoor access to promote the animal welfare. This may increase the risk of infection of the common pig parasites, Ascaris suum and Trichuris suis, because their eggs can survive for many years in the soil. The egg contamination of these parasites in outdoor areas with different managements and the faecal egg output from the pigs was investigated on 11 Swedish organic pig farms in 2008. We found eggs of A. suum and, to a minor extent, T. suis in the soil from outdoor areas, which had previously been used for pig rearing and/or for s

Abstract:

In the last few years, there has been an increase in outdoor pig production in many countries. Outdoor herds, on average, are still less productive than indoor herds, often due to higher pre-weaning piglet mortality. Hypothermia is one of the most important underlying causes of piglet mortality in early post-natal life (English and Morrison, 1984). Although the extent of hypothermia suffered by the new-born piglet in an indoor system has been demonstrated (Pattison et al, 1990), no data of this kind are available regarding the outdoor situation.

Due to its distinct properties, wild boar meat is considered a highly desirable consumer product, in a market that is expanding. Outdoor production is also favoured by consumers who value animal welfare and environmental sustainability when choosing meat products. There is evidence that farms that include pasture for grazing typically have reduced feeding costs. Such production systems can also be more environmentally sustainable as the input (pasture) is inedible to humans, compared to conventional indoor systems, which use human-edible feeds (e.g., soya).

Previous studies have focused on dietary modification as a way of reducing rooting behaviour and pasture damage (e.g. Braund et al. 1998). Although these methods helped to reduce rooting behaviour they were ineffective at decreasing long-term pasture damage. This experiment examined the effectiveness of providing a speci

Traditionally fed outdoor sows at commercial stocking rates can deposit onto soil in excess of 500 kg of nitrogen per hectare per annum from unused dietary nutrients. This has the potential to give rise to serious environmental pollution problems, and it is therefore important to seek methods to reduce this amount or to influence its pollution potential. One major determinant will be the extent to which it can be captured and utilised in grass growth, but this will be dependant on the extent to which the rooting activity of the pigs has destroyed the vegetation cover.

Abstract:

The competent authorities of the Member States of the European Union are required to perform animal welfare inspections on livestock farms. The data obtained from these official inspections performed in Finnish cattle and pig farms in 2010–2015 were used with the aim of estimating the prevalence of the most common non-compliances and identifying underlying risk factors. The prevalence of non-compliant cattle and pig farms was 24.2% and 27.9%, respectively. In cattle, the most common problem was an inadequate lying area followed by deficient housing conditions for calves; in pigs, it was a lack

Abstract:

The presence of Listeria monocytogenes in the pork production chain was followed from farm to slaughterhouse by examining the farm and slaughterhouse levels in the same 364 pigs, and finally by analyzing the cut meats from the same pig lots. Both organic and conventional farms were included in the study. Altogether, 1,962 samples were collected, and the 424 L. monocytogenes isolates were analyzed by pulsed-field gel electrophoresis. The results from microbial analyses were combined with data from an on-farm observation and a questionnaire to clarify the associations between farm factors and pr

Abstract:

AbstractOpportunities for alternative swine production and marketing are emerging across the value chain. Given the developing nature of the differentiated pork industry, measurements of niche performance and success are not yet fully known. For this reason, the objectives of this study were to determine performance metrics across all major life phases for niche pork production and compare such metrics with national averages of conventional commodity pork production. Additionally, this study aimed to quantify producers’ reasoning and barriers to successfully raising niche swine. Niche meat pro

Transmission ofOesophagostomum dentatumandTrichuris suiswas studied in outdoor reared pigs. Six farrowing paddocks were naturally contaminated in May to mid-June 2001 by experimentally infected seeder pigs. In early July 1 sow farrowed on each paddock and starting at week 3post-partum(p.p.) the offspring was slaughtered serially every 2 weeks for parasite recovery. Faeces were collected regularly for parasite egg counts and acid-insoluble ash (AIA) content as an indicator of geophagy. Weaning took place at week 7 p.p. by removing the sow. Paddock infection levels were estimated in mid-June (O.

Abstract:

Nose ringing is widely used in conventional outdoor pig production as the only reliable method of preventing sows destroying pasture by rooting (Edwards et al., 1998), but is prohibited by some organic sector bodies as it inhibits the sows’ behaviour. Some organic producers use a rotation policy in which the sows are moved to fresh pasture about three times a year, after green cover has been destroyed. As well as limiting nutrient leaching, frequent movement also limits parasite build-up in a system which prohibits the routine use of anthelmintics. However, it has a high labour demand. An alte

Abstract:

In pig production, the widespread conventional indoor system with a slatted floor currently dominates. However, this production system is becoming less socially acceptable. In addition to general environmental protection issues, animal welfare, the absence of suffering and distress, and the management of pain also constitute societal concerns. In this context, alternative production systems are gaining ground. Although they are popular with consumers and other citizens, these alternative systems have their critical points. Here, we reviewed the international scientific literature to establish

Abstract:

Climate control is of the foremost importance in structures for intensive animal rearing because many animals (e.g. pigs and broilers) tolerate a small range of climate conditions (mainly air temperature and relative humidity) that may differ considerably from the outdoor environment. For this reason, the indoor climate in the majority of structures for animal husbandry is guaranteed by HVAC systems. On the one hand, the use of mechanical systems makes it possible to avoid production risks due to the unpredictability of the outdoor weather conditions and to maximize the feed efficiency, with p

Abstract. Title of the paper: Systematic crossbreeding as a tool to conserve endangered pig breeds Live conservation of purebred populations of old endangered pig breeds requires high financial subsidies because they are very inferior to actual commercial hybrids in overall economy. But subsidies may be considerably reduced if the endangered breeds can be integrated into regional crossbreeding schemes adapted to ecological production niches or designed for specific quality products.
