Pigs have a panoramic vision of 310º and binocular vision of 35-50º (Fig. 1). This means that compared to humans, pigs prioritise their lateral monocular vision and this increases their panoramic vision (greater capacity for detecting possible danger, food, other pigs, etc) and decreases their bifocal vision (greater difficulty for calculating distances).

Preventing vertical and horizontal spread of PRRSV from dam to offspring is critical for the production of naive replacement stock

The PHP 160 billion hog industry is the second leading contributor to Philippine agriculture coming in second to rice despite being almost exclusively without government subsidy.

Pigs must have permanent access to a sufficient quantity of material to enable proper investigation and manipulation activities, such as straw, hay, wood, sawdust, mushroom compost, peat ...

This is the first of a series of articles written by Tom Alexander for www.3tres3.com which we would like to publish again here as a way of paying homage and showing gratitude for his invaluable collaboration.

The objective of drinking device management is to provide water at a rate that satisfies the pigs thirst without either limiting intake because the rate of delivery is too low or resulting in increased spillage due to a rate that is faster than the pig can swallow.

Control of PCV2 infections are increasingly through piglet vaccination now that global supplies are increasing.

The presence of subpopulations of exposed and non-exposed sows in chronically PRRSV-infected breeding herds assists in the maintenance of virus circulation in the breeding herd over time.

Porcine circovirus type 2 (PCV2) infections can be extremely costly causing wasting and increases in mortality.

The purpose of a ventilation system is to remove excessive moisture and heat produced by animals in order to maintain an indoor climate within certain limits

It is assumed that the most probable route of PCV2 transmission is the oronasal tract, which would indicate that horizontal transmission (sow-piglet or piglet-piglet) is a frequent or very frequent occurence

The research data suggests that feeders designed for ad libitum feed access with diets in the mash form should have approximately 40% of the feeder pan covered with feed.

In the first of this series of articles on respiratory disease in pigs, the causes of coughing were reviewed. This second article reviews the production factors that are associated with respiratory disease.

In a previous article (March '99) we suggested a standardized terminology for the description of swine production systems. The terminology covered stages of production (breeding, nursery, finishing), management practices (isowean, sourcing of pigs, movement of pigs), and physical aspects and geographical locations of production facilities (numbers of buildings, loci, and sites).

A new proposed system for terms to use in describing the various one site and multi-site production systems that have evolved in the pork production industry, and a simplified system for diagraming various types of pig farms.
