Abstract
The effect of choline supplementation (434 mg/kg of diet) on reproductive performance and incidence of spraddle leg condition in baby pigs was studied in two experiments, using 128 gilts (64 Lacombe + 64 Yorkshire) in exp. 1 and 64 primiparous sows and 64 gilts, half from each breed, in exp. 2. In exp. 1 (winter) supplemental choline significantly (P < 0.05) increased the number of live pigs born (9.64 ± 0.41 vs. 7.90 ± 0.31) and weaned (7.50 ± 0.68 vs. 6.73 ± 0.25) for Lacombe, but not for Yorkshire (8.40 ± 0.56 vs. 9.00 ± 0.45 and 7.40 ± 0.33 vs. 8.10 ± 0.33, respectively) gilts. The mean birth weights and weight gains to 3 and 5 wk of age were similar for the control and choline-supplemented groups. In exp. 2 (summer) choline supplementation had very little effect on reproductive performance of gilts or sows from either breed. The incidence of spraddle leg condition was very low in both experiments and was not influenced by choline supplementation. These results indicate that the choline content of barley-wheat-soya diets was adequate for reproduction in Yorkshire gilts and sows, but Lacombe gilts may require supplemental choline during winter for optimum reproductive performance.
