Injecting prostaglandin F2α (PGF) or its analogues is effective for induction of farrowing, although a large range in the interval between treatment and farrowing is usual. Experience has shown that only 50% to 60% of PGF-treated sows farrow during the working day after injection and only these sows are candidates for farrowing supervision.

Until now we have spoken about the general parity structure of the herd, but in an ideal situation this optimum distribution should be put into practice in each of the productive batches of sows.

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

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.

For hormones to be efficient it is essential to use them with the right approach. For this we must know the reproductive cycle of the sow and the hormones that are involved.

Colostrum offers 3 essential properties to the piglet: very useful energy source (vital for generating movement and avoiding temperature loss), immune supply (protects against germs that the piglet begins to come into contact with) and natural growth factors (complete the maturity of the piglet).

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.

Normally the productivity of the sow is valued for the number of litters/sow/year multiplied by the number of weaned piglets per litter.

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.

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

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.
