Dietary fenugreek seed extract improves performance and reduces fecal E. coli counts and fecal gas emission in lactating sows and suckling piglets. Can. J. Anim. Sci. 95: 561-568. This study evaluated the efficacy of fenugreek seed extract (FSE) in sows and suckling piglets. The trial was conducted with 78 multiparous sows and their litters in a 28-d feeding trial, and one of three diets: CON (control, basal diet); FSE1 (basal diet 0.1% FSE), and FSE2 (basal diet 0.2% FSE). Piglets suckling sows fed the FSE1 and FSE2 diets had higher average daily gain compared with those suckling sows fed the CON from week 2 to weaning (linear, P<0.05). At weaning, sows fed the FSE1 and FSE2 diets had higher immunoglobulin G and lower low-density lipoprotein-cholesterol concentrations compared with those fed the CON diet (linear, P<0.05). Sows fed the FSE2 diet linearly reduced total cholesterol concentrations at weaning (P<0.05). Piglets suckling sows fed the FSE2 diet had higher immunoglobulin G and red blood cell concentrations compared with those suckling sows fed the CON diet (linear, P<0.05). Sows fed the FSE2 diet had higher apparent total tract digestibility of N and gross energy and reduced fecal E. coli counts and ammonia gas emission compared with those fed the CON diet at weaning (linear, P<0.05). In conclusion, results indicate that feeding sows a diet supplemented with FSE in late gestation and lactation improved performance in sows and suckling piglets.
