Abstract

Prebiotics are widely used in the swine industry to enhance sow and piglet performance. Euglena gracilis, a β-glucan-rich prebiotic derived from algae, has shown potential to enhance immunity and promote growth of animals. This study evaluated the effects of maternal E. gracilis supplementation during late gestation and lactation on sows reproductive and piglet performances, serum and colostrum immunoglobulin (Ig) concentrations, and colostrum and milk compositions. A total of 61 crossbred sows (Landrace × Yorkshire) were categorized into parity classes and randomly assigned to either a standard diet (control; n = 30) or the standard diet supplemented with 1 g per day of E.gracilis (E.gracilis; n = 31) from day 85 of gestation to day 21 of lactation. Sow and piglet performances were monitored from birth until day 21 of lactation. Blood and colostrum samples from sows at farrowing and piglet blood samples on day 21 of lactation were analyzed for IgG, IgA, and IgM. Colostrum and milk samples (days 3 and 10 of lactation) were evaluated for chemical compositions. Supplementation of E. gracilis did not affect sow reproductive performance. However, piglets suckled by E. gracilis-supplemented sows had greater body weight on day 21 of lactation than those from the control group (P = 0.047). Colostrum samples collected from E. gracilis supplemented sows had greater concentrations of IgG (P = 0.036), protein (P = 0.012), casein (P = 0.008), and Brix index (P = 0.043) compared to the control group. However, the chemical composition of milk on days 3 and 10 of lactation did not differ between the groups. Piglets suckled by sows supplemented with E. gracilis had lower serum IgM level than those suckled by the control sows (P = 0.007). In conclusion, E. gracilis supplementation in sow diet during late gestation and lactation enhanced colostrum quality, thereby enhancing piglet growth during the suckling period.

妊娠后期和哺乳期母猪补充细叶茅β-葡聚糖可提高初乳免疫球蛋白G水平，提高仔猪生产性能

益生元被广泛应用于养猪业，以提高母猪和仔猪的生产性能。细叶藻（Euglena gracilis）是一种从藻类中提取的富含β-葡聚糖的益生元，具有增强免疫力和促进动物生长的潜力。本研究评价了妊娠后期和哺乳期母猪饲粮中添加细叶乳杆菌对母猪繁殖性能和仔猪生产性能、血清和初乳免疫球蛋白（Ig）浓度以及初乳和乳成分的影响。选用61头长白×约克郡杂交母猪，按胎次分类，随机分配标准日粮组(对照组；n = 30)或在标准日粮中添加1 g /天的股薄叶泻子(股薄叶泻子；N = 31)从妊娠第85天至泌乳第21天。从母猪出生至泌乳第21天监测母猪和仔猪的生产性能。分析母猪产犊血液、初乳和仔猪泌乳第21天血液中IgG、IgA和IgM的含量。测定初乳和乳样品（泌乳第3天和第10天）的化学成分。添加细叶菊对母猪繁殖性能无影响。然而，在泌乳第21天，添加细叶菊的母猪的仔猪体重高于对照组（P = 0.047）。母猪初乳中IgG （P = 0.036）、蛋白质（P = 0.012）、酪蛋白（P = 0.008）和Brix指数（P = 0.043）的含量均高于对照组。然而，在哺乳第3天和第10天，各组之间的牛奶化学成分没有差异。饲粮中添加细叶菊仔猪血清IgM水平低于对照组（P = 0.007）。综上所述，妊娠后期和哺乳期母猪饲粮中添加细叶菊可提高初乳质量，从而促进哺乳期仔猪生长。

期刊介绍： Animal Feed Science and Technology is a unique journal publishing scientific papers of international interest focusing on animal feeds and their feeding. Papers describing research on feed for ruminants and non-ruminants, including poultry, horses, companion animals and aquatic animals, are welcome. The journal covers the following areas: Nutritive value of feeds (e.g., assessment, improvement) Methods of conserving and processing feeds that affect their nutritional value Agronomic and climatic factors influencing the nutritive value of feeds Utilization of feeds and the improvement of such Metabolic, production, reproduction and health responses, as well as potential environmental impacts, of diet inputs and feed technologies (e.g., feeds, feed additives, feed components, mycotoxins) Mathematical models relating directly to animal-feed interactions Analytical and experimental methods for feed evaluation Environmental impacts of feed technologies in animal production.
