In the last chapter on hormone management we looked at the advantages of “a la carte” altrenogest treatment as opposed to the 18 day treatment used to synchronize gilts.

In this chapter the use of progesterone derivatives to modify the duration of estrus in sows is explained.

A good result in stillbirths is difficult to achieve without inducing farrowings.

In this chapter we will present the farrowing stages and how to control it.

In Denmark the most common practice is to always stimulate with the boar together with a complete 5 point pattern of stimulation carried out by the inseminator.

In addition to amino acid intake, proper energy intake is essential for maximizing milk production in sows. Both the amount of and type of energy can influence milk production.

The milk production of sows is one of the parameters that has evolved the most over the last several decades.

In this chapter we will take a look at some other aspects of farrowing induction...

This may be a good option when farrowings and litter control during the first days are the priority.

On large farms, it is common to wean more than once per week. This way, tasks can be homogenized throughout the week: each day will have a similar volume of work as the previous day.

Despite the increases in the pork supply, deficit scenarios are expected in the 1st and 2nd quarters of 2011.

A large part of the work on a swine farm can be divided into 3 key tasks: weaning, mating and farrowing. The day chosen for weaning determines the other two tasks; first, the matings, and then, as a consequence, the farrowings (the 2 ‘great events’ of which productivity of a farm depends on).

In the last chapter we examined mating guidelines that came rather close to being ideal, given that they achieve the following objectives: At least one mating should be adjusted to meet the ideal time and achieve the first objective with the least number of matings.

The ideal mating guideline should follow 2 objectives: At least one mating should be adjusted to meet the ideal time and achieve the first objective with the least number of matings.

As mentioned in the previous chapter, theoretically, the ideal mating time is around 10-12 hours before ovulation.

The optimal fertilization of a sow depends on several factors, among them, mating in a specific moment of the oestrus.
