The ideal sow herd structure does not have a triangular shape any more
Traditional culling policies have a threshold number of farrowings after which sows are culled —after weaning. But, what would happen if this policy were to be modified to actually consider the performance of each sow?

08-Dec-2017Marcelo PeterI love these article, i was upset with my veterinary officer who failed to offer me such an advice when i had challenges of feeds, mastitis and too many sows on the farm.
I just have all my answers well articulated here.
Thanks to these teams for shining this bright lights.

Hyperprolific? Yes, but not so much
Sows with more than 16 piglets Total Born (TB) per litter have twice as many stillbirths (SB) as those with 13 to 16 TB litters, and three times more SB than sows farrowing litters smaller than 13 TB.

4 week batch farrowing: another option for small farms
This article discusses 4-week batch farrowing (4WBF), very common in small farms (250 sows) in some other countries, including France. Analysis will be based on a comparison with 3-week batch farrowing (3WBF).

"Ghost sows" and the other 8 most frequent errors when processing data (1/2)
This first part deals with backward and impossible data, i.e. the sows that are no longer in the farm but still appear both in the management softwatre and the 100% delivery rates in gilts.

Lameness blindness (2/2)
The number of sows that suffer some kind of leg injury is much higher than is apparent, and even more so in second farrowings.

What is the best age for the first service? Well, it depends
The month of the sow's birth affects the number of piglets born alive in the first farrowing.

27-Feb-2016ZOOTECHDear Bvendelboe, Allow me to disagree with you, Genetics is a very delicate issue, 16 piglets is not standard for any genetic. Your choice of genetics, maybe depends on the type of pigs you produce, so it's not "correct" to conclude. Back to our topic; It's a rule that gilts are not served before 270 days of age, and the more we approach the 300 days deadline the better parity performance you get, meaning a better ROI per gilt properly selected & served.
At long last, we can now predict a sow's performance from her first farrowing
We can predict a sow's production based on the number of piglets born alive at first farrowing. In addition, the best sows' performance will outdo the others' continuously.

Are sows asking for the pig334? (1/2)
As you probably know, the name pig333 web comes from the length of the sow's gestation, which is "3 months, 3 weeks and 3 days". This paper proposes the necessity to review the length of gestation on our farm.
