The objective was to evaluate the effect of phytogenic supplementation in the feed of lactating sows on the performance parameters of sows and suckling piglets. Ninety-three lactating sows of commercial lines (sows TN70) were distributed in a completely randomized design. The treatments adopted were a control diet without phytogenics (control) and a control diet with phytogenic supplementation in the feed. Performance parameters and the behaviors of sows and piglets were evaluated, in addition to milk composition and the biochemical parameters of the animals. The use of phytogenics did not affect the feed intake or tissue mobilization of the sows. However, it improved the production and quality of milk and reduced the possibility of light piglets at weaning by 22.16 percentage points. Regarding biochemical parameters, phytogenics improved animal recovery in the lactation period, as proven by an increase in the serum concentration of total protein and urea. Sows that received phytogenics exhibited increased behaviors of inactivity (3.16%), breastfeeding (1.15%), and water consumption (0.95%). In conclusion, using phytogenics in the feed of lactating sows improves the performance of the litters without affecting the body condition of the sows, with increased milk production and enhanced protein and lactose concentration.
目的是评估在泌乳母猪饲料中添加植物源添加剂对母猪和哺乳仔猪生产性能参数的影响。93头商业品系的泌乳母猪（TN70母猪）采用完全随机设计进行分配。采用的处理方式为不含植物源添加剂的对照日粮（对照）和在饲料中添加植物源添加剂的对照日粮。除了评估母猪和仔猪的生产性能参数及行为外，还对乳汁成分和动物的生化参数进行了评估。使用植物源添加剂并未影响母猪的采食量或组织动员。然而，它提高了乳汁的产量和质量，并使断奶时仔猪体重较轻的可能性降低了22.16个百分点。关于生化参数，植物源添加剂改善了泌乳期动物的恢复情况，总蛋白和尿素血清浓度的增加证明了这一点。接受植物源添加剂的母猪表现出不活动行为（增加3.16%）、哺乳行为（增加1.15%）和饮水行为（增加0.95%）。总之，在泌乳母猪饲料中使用植物源添加剂可提高仔猪的生产性能，且不影响母猪的体况，同时增加了乳汁产量，提高了蛋白质和乳糖浓度。
