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 (2/2)

"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.

Apparently, lameness problems amount to just 5% of the causes for sending pigs to slaughter...

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.

Data, hormones and holidays (2/2)
This article explains how the massive use of hormones helps synchronize heats and farrowings when workload scheduling, synchronization and production rates stability are priorities.

Data, hormones and holidays (1/2)
A strict schedule allows us to concentrate all the important events, and time periods where more attention/work is required, within the working days.

Are sows asking for the pig334? (2/2)
Thanks to the combination of a decrease in the number of stillborn and an almost 30% decrease of preweaning mortality (down to 10.2%), the ultimate goal is finally achieved: to wean an additional piglet per sow.

30-Apr-2015GhenadieLow birth weight and high stillborn percentage are common for early induced farrowing. Most of our farms have weekly batches. Some of them are using prostaglandin on day 116 in sows with no signs of farrowing to reduce the distribution of farrowing in the same batch. Some of our farms are just switching not farrowed late sows with farrowed ones in the next room to close the batch earlier. This way we reduce intervention and cost for hormones and following a more natural way. Last 10 years the gestation length increased with about 1 day. In our farms the average gestation length is 116,3-116,5 days.
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.

Non-productive days (2/2): €16,000 hidden in the gestation
After checking that our farm loses days in the servicing of the gilts, the detection of empty sows housed in yards and the culling (sending of the sows to the abattoir), we propose a package of measures…

Sow overmanagement consequences (2/2)
The results reveal that the stress that the sows due to excessive interventions around the moment of the farrowing causes a clear increase in the pre-weaning mortality.

Sow overmanagement consequences (1/2)
We saw aggressiveness in the sows, and we suspected that it could have been caused by the handling around the moment of the farrowing. We decided to register and analyze the data relative to the handling in order to confirm our suspicions.

26-Mar-2014mester.karoly_1The question is not so simple. Increase the fermentable fiber is a good idea, but it does not resolve the issue.
The sow's head two interesting symptom. The eye conjunctiva inflammation. The sow mouth on the edge of white foam. In which I am not sure, but I see the picture of the sow snout skin tissue necrosis.
This causes additional problems. I think that the sow does not compensate, combo, acidosis, metabolitikus and respiratory system eye visible symptom. The other big problem with the release of ammonia poisoning, a symptom of the frothing at the mouth.
To compensate for the acidosis enters the renal route, this is known as escaping the glutamine → 2 HCO3- + 2 NH+ 4. The kidneys of the ammonium ions should choose, but I do not know. At this point, the Organization would reach the goal of having a glutamine residue, namely the two breaks down to HCO3-ion which would compensate the acidosis. Further it is possible to process the liver detoxication function where the urea cycle in the detoxication of ammonia. The liver does not go in the urea cycle,
Two reasons
1. small number of intact liver parenchyma cells in the liver.
2. lysine-arginine antagonism of the urea cycle, unable to function.
This causes the ammonia poisoning. Due to the unfortunate sow liver and kidney damage.
The acidosis can develop kidney problems, liver problems due to ketosis is the sow it causes a huge acid load the animal. The respiratory acidosis due to kidney failure can develop.
Renal insufficiency → blood pressure increase → hypertrophic heart in work → blood stasis in the pulmonary circulation → pulmonary oedema → reduced the effectiveness of respiration, carbon dioxide exhalation → respiratory acidosis.
Ammonia poisoning symptom:
Ammonia is added to the liquor, the displacement of the ammonia paralyses muscle motor cells. Therefore, you can not swallow the sow, so it builds up in the saliva foam in the mouth. The nervous excitement of ammonia poisoning is caused by the State. Muscle tremors, gnash one’s teeth, panic condition.
Notice the pregnant sows is ammonia poisoning.
Why is there such a high mortality in the piglets ?
1. Prenatal asphyxia can also be due to prenatal. In this case, the hogs are special acidosis in utero. At this point the piglets the blood pH from 6.0 to pH also may be affected. Due to the vitality of these pigs have no life.
2. the characteristic of the meconium birth of a pig?
3. you must have surfactant deficient piglets.
4. you see mulberry heart disease neonatal piglets?
5. do you have the villous atrophy in piglets?
Wrong thinking.
There is no shortage of animals symptom, not the problem that we do not do something in the feed mixture.
Solving the problem is that some of the material to be removed from the feed mixture!
Wisely.
This is a serious nutrition physiological causes. I feel sorry for the animals, and the economic damage is enormous.
I have been doing for years. There are a lot of practical experience.
It is not easy, but it can be removed.
Unfortunately my English is not good. Excuse Me.
