Without adding more space, the only way to accommodate an increase in weaning age is to decrease the breeding herd inventory.

An economic model was developed that assessed financial loss through the pyramid from nucleus to multiplier to commercial herd on a per litter basis for traits with an incidence higher than 0.10%.

A survey was undertaken in a large anonymous European Breeding Company over a four year period ending March 2010. In total, 175843 pigs born were evaluated to establish the incidence of congenital defects and additional assessments were made at 95kg. More than half the total defects were identified in the growing and fattening period rather than at birth.

Here we present a new section about the economics of swine disease: the first presentation is about the economic benefits of disease control in swine barns.

Porcine Respiratory Disease Complex (PRDC) is the result of a complexity of events, including infections, environmental factors and host’s immune system weakness deriving from genetic causes.

The most common problems are due to interference with maternal antibodies and coincidence of vaccination with a recirculation of PRRS: viremic animals.

There is sufficient genetic variation in host response to infection to allow future breeding goals for enhanced resistance or tolerance so that there are grounds to believe that it may be possible to breed commercial animals that have increased genetic resistance or tolerance to the disease.

As better information systems capable to measure change in disease patterns, vector distribution and environmental conditions are put in place, we may be surprised about the range of diseases directly or indirectly already affected by climate change.

With the earth warming up there is evidence of accelerated changes in habitat distribution changes that in turn may be affecting disease patterns and emergence of diseases.

To many pig producers cleaning and disinfection is a chore they view as an expensive tedious burden.

The best approach is to submit dead pigs or live affected pigs to the diagnostic laboratory for post-mortem examination.

There are 15 recognised serotypes of APP (designated 1 – 15) that greatly differ in their virulence potential.

As a result of dedicated implementation of guidelines for the progressive zoning approach, the zero case scenarios was sustained to date, with continuous complementation of stricter animal movement management and sustained cooperation of all concerned stake holders. Luzon at present is virtually divided into three zones.

The recognition of Mindanao and Visayas-Palawan-Masbate by OIE as FMD free zones without vaccination were two of the most significant achievements by the National FMD Control and Eradication Project.

Complete examination of the urinary system is possible on a post mortem examination.

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.
