An Overview of Methods for Measuring the Impact of Sanitation Procedures for Swine Transport Vehicles

Publish Date: 04/10/2009

In todays swine industry, biosecurity protocols are perceived to be extremely important in order to protect the health status of a herd. While the easiest way to introduce a microorganism into a swine herd is through the introduction of infected animals, the potential for pathogen entry via contaminated fomites, i.e. boots, transport vehicles, etc. has…

How to mix gestating sows housed in groups

Publish Date: 11/14/2014

Due to specific state legislation or market requirements many farms will have to house gestating sows in groups. Management practices will have to be modified for farms to be successful when housing sows in groups during gestation. Gilts and sows have a dominance hierarchy based on aggression and avoidance. Fighting among sows mainly occurs during the first 2 to 3 hours after mixing. The hierarchy is primarily established within 24 hours. An important consideration will be how to mix sows and gilts in groups to reduce overall, prolonged aggression. This article will provide guidelines that can be used to formulate standard operating procedures for mixing sows into gestation pens. For this ‘How-To’ sheet, it will be assumed that females (gilts and sows) will be mixed after they are mated.

Heat Exchangers in Swine Facilities

Publish Date: 04/04/2012

Ventilation air-to-air heat exchangers are used in swine housing facilities to reduce supplemental heating cost and to preheat incoming fresh air. There is potential for heat exchanger use in some swine barns, since as much as 90% of the total heat loss from an insulated swine nursery facility occurs through the minimum ventilation air exchange. Heat exchangers recover a portion of this loss, depending upon design and maintenance. In addition to reducing fuel use, heat exchangers preheat the incoming ventilation air thereby reducing the potential for drafts on piglets and reducing frosting problems when air enters directly from outside. Heat exchangers also improve air distribution, because warmed inlet air will not drop as rapidly as cold inlet air.

Facility Maintenance and Modernization

Publish Date: 06/06/2006

A general understanding of the operation of swine facilities is required in order to develop a maintenance program. The objective of this paper is to provide an understanding of swine facility operation and to indicate key areas necessary for an effective maintenance program. Any implemented maintenance program may or may not require all key areas…

Effect of Pen Density on Nursery Pig Performance

Publish Date: 09/18/2006

Purdue University 1997 Swine Research Report. The implementation of improved health management strategies including segregated early weaning and all-in, all-out rearing has resulted in increased post-weaning growth. The improved growth rate in turn results in pigs achieving 60 to 70 lbs. live weight after 6 to 8 weeks in the nursery. Limited research has been…

An Evaluation of Growth Performance in Swine Raised in Commercial and Unrestricted Environments

Publish Date: 09/18/2006

Purdue University 1998 Swine Research Report. Environmental factors including disease exposure, social stress and less than optimal stocking density limit growth. As a result, pigs managed under commercial conditions are unlikely to express their maximum potential protein accretion, even when allowed ad-libitum access to a high quality, nutrient dense diet. The operational protein accretion is…

Measuring emission rates of particulate matter from fan ventilated swine barns

Publish Date: 09/07/2006

Kansas State University Swine Research. Methods for measuring concentrations and emission rates of particulate matter (PM) from mechanically ventilated livestock buildings were evaluated in a laboratory facility and in a swine-finishing barn. Concentrations of PM were measured inside the room (room sampling) and at the exhaust duct (exhaust sampling). Concentrations at the exhaust duct were…

Comparison of Bioaerosol sampling methods for swine barns

Publish Date: 09/07/2006

Kansas State University Swine Research. Two bioaerosol sampling methods (Andersen sampler and filtration sampler) were compared. The two samplers were used to assess the bioaerosol loads in two swine finishing barns. They were similar in terms of the species of microorganisms sampled. The persistent strains of microorganisms were various species of the following genera: Staphylococcus,…

Use of infrared thermography to evaluate differences in mean body surface temperature and radiant heat loss in growing pigs

Publish Date: 09/07/2006

Kansas State University Swine Research. Eighty barrows were used in two experiments to determine the relationship between feed intake or dietary energy concentration and mean body surface temperature (MBST) and mean body surface radiant heat loss (MBSL) as measured using infrared thermographic images. In Exp. 1, feed intake level was varied. As expected, pigs with…

Examination of Stocking Density and Marketing Strategies in a Commercial Production Environment

Publish Date: 09/07/2006

Kansas State University Swine Research. The influence of stocking density (7.4 or 6.6 sq ft per pig) and marketing strategy (0, 1, or 2 sorts before closeout) was examined in a commercial production environment. No interaction between stocking density and marketing strategy was observed. Higher stocking density had no negative effects on growth performance or…
