摘要

Goat production is increasing in the USA due to high ethnic demand, but infection with gastrointestinal nematodes (GIN) is a major constraint to the industry. Increasing GIN resistance to chemical anthelmintics world-wide has led to the development ofalternative control strategies, including use of forages containing condensed tannins (CT). Sericea lespedeza [SL, Lespedeza cuneata (Dum-Cours.) G. Don], a high CT forage, has been shown to reduce GIN levels in goats when fed as hay, but little is known about its effect on growth rate in young goats. An experiment was designed using infected and non-infected male kids (Kiko X Spanish, 6 mo. old) fed diets consisting of 75% hay [SL or bermudagrass (BG; Cynodon dactyon (L.) Pers.)] and 25% concentrate (n = 10 per treatment). The kids were weighed every 2 weeks, and fecal and blood samples taken weekly for fecal egg count (FEC) and packed cell volume (PCV) determination, respectively. Parasite infection levels were relatively low in both infected groupsby the end of the trial, but SL infected kids had consistently lower (P<0.05) FEC and higher (P<0.05) PCV than the BG infected goats. The SL infected and non-infected kids gained 0.22 and 0.24 1bs/d, respectively, compared with 0.16 and 0.18 Ibs/d in BG-fed kids. Feeding SL hay reduced GIN infection levels and increased animal performance compared with BG hay, suggesting that the CT in this plant had beneficial nutritional and anti-parasitic properties.

Don]，高CT牧草，已被证明在喂养干草时减少山羊的杜松子酒水平，但对幼山羊的生长速度几乎不了解。使用受感染和无感染的男性儿童（Kiko X西班牙语，6 Mo。旧）设计了一个实验。喂食饮食，包括75％干草[SL或百慕大（BG; Cynodon丁磺（L.）。）和25％浓缩物（每次治疗n = 10）。儿童每2周重量，每周服用粪便和血液样品，分别为粪便蛋计数（FEC）和包装细胞体积（PCV）测定。在试验结束时，寄生虫感染水平相对较低，但SL感染的孩子始终如一（P <0.05）FEC和更高（P <0.05）PCV而不是BG感染的山羊。与BG喂养的儿童中，分别分别为0.22和0.24 1bs / d，分别感染和未感染的儿童。与BG干草相比，喂养SL干草降低了GIN感染水平和增加的动物表现，表明该植物中的CT具有有益的营养和抗寄生性能。
