In this chapter we will look at how hormones can be used to influence the time of farrowing according to our needs.

In reproductive disease, submission of several whole affected litters is advisable to provide material for diagnosis of PRRSV and other diseases causing reproductive or neonatal problems.

The gestation unit is basically a parking unit where sows should be kept comfortable to allow the pregnancy to develop

When the sow is pregnant, the corpus luteum remains and continues to produce progesterone. While the levels of progesterone are high the sow does not become in heat and maintains gestation.

Low maternal feed levels cause a reduction in muscle fibre numbers, whereas enhanced maternal nutrition resulted in a higher number of muscle fibres in specific muscles.

Since 1987, Porcine Reproductive and Respiratory Syndrome virus (PRRS) has become a global drain on pig productivity, profitability, and many a producers’ morale. One thing that remains certain is PRRS virus continually finds ways to circumvent our best bio-management efforts. PRRS marches on in a ceaseless continuum of antigenic change making current vaccines and other control techniques of limited value.

A breeding chart would be like a type of computer without wires, screen or keyboard.

Piglets face a very stressful process at weaning and feed intake becomes one of the most limiting issues.

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

Although many studies have shown that addition of fat to sow diets during late gestation can improve piglet status at birth and growth performance before weaning, less attention has been placed on the type of fatty acid in the diet and how specific fatty acids might improve piglet growth and survival.
