The problem of pain

Written to Coba Coba by Novalima

Our greatest challenge today...is to couple conviction with doubt. By conviction, I mean some pragmatically developed faith, trust, or centeredness; and by doubt I mean openness to the ongoing changeability, mystery, and fallibility of the conviction.
- Kirk Schneider, 1999, The Paradoxical Self, p. 7

This week was more about fallibility than conviction. We continue to have problems with the gilts savaging and cannibalizing their piglets in an incomprehensibly heartbreaking fashion. This behavior, which tears at the very core of our conviction, seems to fly in the face of Mark Twain's quote that 'nature knows no indecencies'.

The locals, i.e. the residents of Vargem Grande, are convinced that this is happening because our hogs are hungry, which hardly explains why only the mothers are cannibalizing their piglets, nor how the 'good' mothers are nursing their young outside the maternity houses, in plain view of the purportedly 'hungry' hogs, none of whom show more than a passing, good-neighborly interest in the new, smaller denizens of Hog Haven. For his part, Clair has decided that there are too many hogs in our pen, this in spite of the fact that said pen is approx. two hectares in size, considerably more space than the 51.75 m2 that a similar number of hogs would have access to in a confined feeding operation. In a confined feeding operation, each hog would reside in a grand total of 2.25 m2, including piglets. Also, if inexperience is the culprit, it is more than a little odd that things went haywire after the first two successful births, i.e. the Hannibelas (as in Lecter) had two perfect role models after which to pattern their maternal behavior. Furthermore, after gilt #3 savaged and cannibalized her five piglets, gilt #4 gave birth and was nursing her six piglets in the perfect image of motherhood before suddenly, without explanation, she, too, began to savage and cannibalize her young. Fortunately, we managed to save four of the six, which we placed with sow #1. Two of these four piglets are still alive. And as if to complete the maddening incongruity gilt #5 passed on the secure confines of a maternity house and broke the sequence of death by giving birth to five healthy piglets in the open air. In the same way that the well-known Christian scholar, C.S. Lewis, once called the “problem of pain,” atheism's most potent weapon against the Christian faith, the disconsolate truth of this phenomenon is that it defies any form of logic or attempt at explanation. At this point all we can do is either trust our conviction or accept its fallibility -and treasure the 17 healthy piglets that have survived thus far.

Finally, in a positive example of nature's enduring struggle, we were informed this week by the Polícia Militar Ambiental, who visited our fazenda in their continuing battle against poachers who illegally chop down between 5,000 and 10,000 acaí palm trees each week, that they had spotted a very rare, at least for our region, bird, the Lesser Seed-finch, most probably the Chestnut-bellied Seed-finch, or Curio in Portuguese, at Alfheim.

Hey guys, you're doing great!!! don't let a few crazy pigs get you down... I am sure it will all work out beautifully. besides, 17 piglets ain't bad for a couple of gringos. And as for space, Clair told me Sr. Paulo keeps 80 pigs in 200 square metres at his place!!!!! Remember, nothing good comes easy.

Dont get discouraged. (They call them pigs for a reason)

Maybe identify the females that show this behavior and take their newborns immediately and either hand feed them or safely confine them with tried and true females to nurse them.

Hi
I got interested in your problem and was reading up on it a little bit. Your percentage of savaging of 2 out of 5 or 6 gilts/sows is much higher than the published average of about 3%. I do not think that is significant because your total number of births is so small that you can not compare your experience to huge farms.
It does sound like first time parity, environmental factors and probably breed characteristics are all at play here. Reading through various reputable absracts there clearly is no consensus on how to totally prevent this problem.
The reality is that even the huge factory farms that physically confine and control every possible movement have a significant problem with this behavior so clearly it can not be completely eliminated. I have no doubt that as you gain experience you will identify management strategies that significantly reduce the impact of this behavior.
As a non sequitor: Rance I hope you are not completely protected from the evils of mainstream media down there in orgo-land as there is a kickass NBA finals going down with your beloved Lakers tipping off game 4 against Orlando in about 25 minutes, up 2 games to 1.
Keepo up your hard work, I am sure it will pay off.

One last thing:

This abstract seemed to have the largest numbers of gilt/sow births studied that I could find.

62 Savaging in gilts and second parity sows: a study
of seven commercial farms. M.J. Harris*1,2,3 , Y. Li1 , and
H.W. Gonyou1 , 1 Prairie Swine Centre Inc., Saskatoon, Saskatchewan,
Canada, 2 University of Saskatchewan, Saskatoon, Saskatchewan,
Canada, 3 Present address: Purdue University, West Lafayette, Indiana,
USA.
Savaging of piglets by their mothers is a harmful and costly behavior,
the extent and causes of which are largely unknown. A study was con-
ducted to investigate the incidence and correlates of savaging behavior
on seven new 600- or 2400-sow units (n = 4 and 3, respectively) during
their first two farrowing cycles. Females were sub ject to a light (continu-
ous or intermittent light) and sound (newborn piglet vocalizations or no
vocalizations) treatment before and during farrowing. Behavior records
were collected for the first farrowing of 6625 gilts (first farrowing cycle)
and 2175 gilts and 5232 sows (second cycle). The incidence of savaging
and number of piglets killed or injured by it were recorded.
During the first farrowing cycle 331 gilts (5.3%) displayed some piglet-
directed aggression, and of these, 201 (2.9%) fatally savaged one or more
of their young; 392 piglets (.6%) were killed by savaging and a further
114 (.14%) were non-fatally injured. Savaging levels were similar for the
gilts in the second farrowing cycle, while the problems were reduced to
approximately half among the sows. During the second parity, females
that had savaged as gilts were more likely to behave aggressively again
(14%) than those that had not (<1%; p<0.05). There was considerable
variation among farms in reported incidence of savaging and numbers
of piglets affected. During the first farrowing cycle, percentages of gilts
killing one or more of their offspring ranged from .8% to 5.8%, and
percentages of piglets killed by savaging ranged from .1%-1.1%.
During the first farrowing cycle, continuous light resulted in a reduc-
tion in the proportion of piglets fatally savaged (.47 vs. .77 %; p<0.05)
and reduced total reported mortality (.62 vs. .74 piglets/litter; p<0.05)
compared to intermittent light. Gilts farrowing in crates in the cen-
ter of rooms receiving the vocalization playback fatally savaged more
piglets (.12 piglets/litter) than did those in the front (.05 piglets/litter)
or back (.07 piglets/litter; p<0.05). We theorize that increased illumi-
nation allowed gilts to better see approaching piglets, reducing their fear
response. The sound treatment may have disturbed the gilts, and thus
extraneous sounds should be minimized during farrowing

Wow,Tony's last article may well have hit upon something with the idea that the approaching piglets may spook the mother.
I wonder if the researchers ever check for hormone levels in the different mothers to see if that has anything to do with the incidents.
I mean humans have problems being new mothers and some suffer more than others, we have found.
Lastly, our Lakers pushed to a win in OT for a 3-1 lead at this point.
I suspect that you have been following the games, however. LOL
Lots of love to you all.
