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.

Richard can tell you a thing or two about pigs. Hes been rearing them for the last 20 years on his farms in East Yorkshire and Nottinghamshire. Hes also well known in the industry as a tireless campaigner for improved training and higher standards of animal welfare.

One of the main goals for a sow herd is to achieve a correct homogeneity of the productive batches.

When external administration of the hormonal product is stopped, the levels of progesterone fall.

The Danish pig producers’ research organisation has tested a number of different designs. They recommend pen dimensions of 2.7x1.8 m to accommodate modern prolific breeds.

In the first part of management of the breeding chart we basically looked at how it can help us to control returns. In this second part we will look at other applications.

With the current part you can assess your knowledge on pig welfare during the fattening phase: How much space do they need?, What is the maximum level of noise?, etc.

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