The effects of feeding 2 ppm supplemental folic acid (FA) on fetal survival and development were assessed in sows (n = 32). Number of live fetuses and fetal survival at day 45 ± 3 of gestation was not influenced by FA. Fetal pig weight, length, protein and RNA content were increased (P < 0.05) with FA treatment, suggesting enhanced development of embryo/fetal tissues with maternal FA supplementation.

The Impact

The objective of this project was to assess the impact of periconceptional folic acid supplementation on the reproductive performance of prolific and non-prolific ewes, in the estrous and anestrous seasons. Two initial trials took place during the estrous season at two experimental sites where 38 Dorset and 39 half-Finn half-Dorset ewes (site A) as well as 80 Dorset ewes (site C) were divided into two groups receiving either 0 or 210 mg ewe-1 d-1 of folic acid over a period which extended from 21 d premating to 30 d postmating. Three other trials were conducted in the anestrous season where 80 Dorset ewes (site A), 56 half-Romanov ewes (site B) and 78 Dorset ewes (site C) were subjected to the same protocol as the one used in the breeding season. In all the trials, the folic acid supplement increased plasma and red cell folates, but had no effect on fertility, embryonic mortality, or the size or weight of the litter at birth. Folic acid supplementation did not improve the reproductive performance of prolific and non-prolific ewes, either in the estrous season or in the anestrous period.

Acid Administration

In a group of 88 litters (group A), 252 piglets were chosen to measure the effect of folic acid during gestation on hemoglobin (Hb), hematocrit (Ht) and liveweight of piglets at birth, 7 and 14 d after birth. Forty-three dams received 10 intramuscular injections of folic acid during gestation; 45 received no supplemental folic acid in addition to what was present in the diet. Results showed that supplemental folic acid during gestation counteracted the magnitude of the decrease in Hb [Formula: see text] and Ht [Formula: see text] during the first week after birth and tended to increase [Formula: see text] the liveweight of piglets during the second week after parturition. In an second group (group B), 131 piglets from 45 litters were used to measure the effect of folic acid supplementation during gestation on serum iron at 4 and 11 d of age. Twenty-one dams were treated with folic acid and 24 received no supplemental folic acid during gestation. Two weeks after birth, piglets liveweight tended to decrease [Formula: see text] when folic acid was administered to dams during gestation. Serum iron concentrations were similar between treatments at 4 d of age but tended to be slightly higher [Formula: see text] 11 d after birth in piglets from sows injected with folic acid during gestation. Because of the conflicting results, on growth rate, the interpretation of the effect of folic acid during gestation on piglets growth remains ambiguous. However, folic acid administration during gestation did not affect iron body reserves of newborn piglets. Key words: Sow, folic acid, gestation, anemia, piglets
