Evaluating the influence of dietary phytogenic blends on gestating and lactating sows and suckling piglets

This experiment was conducted to determine the effect of dietary inclusion of phytogenic blends on the performance of sows during gestating and lactating period and suckling piglets. Fifty one multiparous sows (Landrace × Yorkshire) were randomly distributed into three treatments (17 sows per treatment): T1 (basal diet); T2 (T1+ 0.05% AC blend (Astragalus membranaceus and Chinese Liquorice); T3 (T1+ 0.05% SL blend (Scutellaria baicalensis and Lonicera japonica). Feeding the sows with diets supplemented with AC and SL blends decreased (P < 0.05) body weight loss after farrowing to weanling. The number of piglets, average daily feed intake, backfat thickness, and estrus interval was not influenced (P > 0.05) by diets. Suckling piglets of sows fed with AC and SL blends showed higher (P < 0.05) weanling body weight and average daily gain weight. Piglet survival rate and birth weight were not affected by treatments. Feeding sows with AC and/or SL blends did not significantly influence the composition of colostrum or milk. There was not any significant impact on fecal score of suckling piglets. These results indicated that supplementation of phytogenic blends to the diet of sows during gestating and lactating period led to a decline in body weight loss after farrowing and could improve litter performance.
