THE EFFECT OF SUPPLEMENTING THE SOW LACTATION DIET
WITH FERROUS FUMARATE AS A PROPHYLAXIS FOR BABY PIG ANEMIA

R. G. Conness, H. D. Wallace and G. E. Combs -I


Several investigations have suggested that it is physiologically impossible to
effectively increase the iron concentration of the sow's milk for the purpose of pre-
venting anemia in the young pig (1, 2, 3, 4, 5, 6, 7). However, recent reports have
indicated that supplementing the sow's diet with ferrous fumarate has been effective
in the prophylaxis of baby pig anemia (8, 9, 10, II).

The purpose of this experiment was to determine if ferrous fumarate in the diet
of the lactating sow would be effective in preventing baby pig anemia. If so, it
was further desired to determine if such prevention was a reflection of an increase
in the iron concentration of the sow's milk or by direct assimilation of iron as a
result of fecal contamination of the premises by the sow.

Experimental Procedure

Seventeen litters consisting of 120 pigs were farrowed in farrowing stalls with-
in a central house floored with concrete. The litters remained in these stalls for
approximately one week at which time they were moved to pens in the same house for
the duration of the trial. The trial was superimposed on a long range experiment to
study the nutritional effects of feeding distillers dried solubles to sows and their
progeny. Sows were therefore allotted to two dietary iron treatment groups accord-
ing to previous diet, parity and breed. The sow treatment groups (Table I) were as
follows:

1. Basal lactation diet.

2. Basal lactation diet plus 900 mg. of iron as ferrous fumarate per pound of
feed.

3. Basal lactation diet with 5 percent distillers dried solubles included.

4. Basal lactation diet with 5 percent distillers dried solubles included
plus 900 mg. of iron as ferrous fumarate per pound of feed.

The sow diets were fed beginning on the 110th day of gestation and continued
through the second week of lactation. The sows were individually fed in a feeding
area separate from the farrowing stalls. The farrowing stalls were kept as free of
fecal contamination as possible.

Within twenty-four hours after the last pig in each litter was born, all pigs
were identified by ear notching. Initial weights and blood samples were taken at
the time of marking. Pigs were allotted to two treatment groups within litters ac-
cording to initial weight and initial hemoglobin level. One-half of the pigs in
each litter received an intramuscular injection of 23.3 mg. of iron at seven days of
age and again at nine days of age. The other half of the pigs in each litter served
as controls and did not receive iron injections.

Final two-week weights and hemoglobin determinations were obtained on each pig.


Results and Discussion

The overall results of this study are summarized in Table 2. Statistical anal-
ysis of the final hemoglobin values failed to show a significant difference due to
sow dietary treatment. There was, however, a slightly higher average hemoglobin
value in those litters from sows receiving the high level of ferrous fumarate. This
difference could be attributed to the assimilation of iron present in the feces of
those sows given the high iron treatment, since it was impossible under the experi-
mental conditions employed to completely eliminate fecal contamination.

Pig hemoglobin analysis showed a highly significant difference (P<.OI) in fa-
vor of those pigs receiving iron injections compared to those pigs not receiving
injections.

Although several pigs had low hemoglobin levels and exhibited symptoms of be-
ing slightly anemic, no fatalities could be attributed directly to anemia.

Weight gains of pigs from the iron-fed sows were greater but the difference
was not statistically significant. Likewise, the injected pigs gained more weight
but the difference was not statistically significant.

The diets containing the high levels of iron did not appear to be unpalatable
to the sows. Symptoms of gastric irritability or diarrhea were not observed.


Summary

The results of this study indicate that supplementation of the sow diet with
ferrous fumarate (900 mg. of elemental iron per pound of feed) did not effectively
increase the concentration of milk iron. Adequate hemoglobin levels were not main-
tained in suckling pigs when they were denied access to the feed and given limited
access to the feces of ferrous fumarate supplemented sows.

Two week hemoglobin levels of pigs receiving iron injections were significantly
(P<.01) above those not receiving injections.

Weight gains in the pigs at two weeks of age were not significantly affected
by either sow dietary treatment or iron injections.
