European Union: new MRLs for altrenogest
Weaning on Friday and using altrenogest to avoid weekend farrowings; is it possible?
What if we were to wean on Friday and were able to block farrowings for 2 days? The bulk of farrowings would be concentrated on Monday.
Hormone management V: Using altrenogest to restore the metabolic state of weaned sows
When gilts were mated at a little more than 100 kg, productivity at 2nd parity had a huge decline and the sow was never able to reach their maximum potential.
Replacement planning and altrenogest management using spreadsheets
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.

Clinical case: Altrenogest for the prevention of premature farrowings
The farm, with an elevated number of animals, had been experiencing for several days an increased number of births in gestation on the weekend before moving the sows to the farrowing pens. Mortality in these births was 100%.
Farrowing induction IV: Guidelines
In this chapter we will take a look at some other aspects of farrowing induction...

Mating guidelines (III)
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.
Mating guidelines (I)
As mentioned in the previous chapter, theoretically, the ideal mating time is around 10-12 hours before ovulation.
Organization of Replacements VI
Adjustment of replacement on farms working on 3-week batch system.
Farrowing programming III
Next we will consider some aspects that can be taken into account in order to adjust the day to induce farrowing.
Organization of replacements V
On many farms the introduction of gilts is not homogenous. However, the introduction of a similar number of gilts to each productive batch would be ideal. How can we do this?
Farrowing programming II
The gestation period in the majority of sows is usually around 113 to 115 days. However, a percentage of sows can farrow normally up to 3 days before or after.
Farrowing batches: keeping the breeding groups full
In the last chapter we looked at the importance of achieving homogenous farrowing batches (age distribution + nº sows). In this chapter we will begin to see how to achieve this.
