摘要
本研究旨在测定补充曲哈糖(Tre)对不同饲养密度(SD)下饲养的肉鸡的生长、肠道形态、肠道细菌和脚垫皮炎(FPD)的影响。将 400 只刚孵化的 Ross 308 公鸡随机分配到四组,每组八只,采用 2 × 2 因式排列的随机完全区组设计,使用两种饲养密度(正常,11 只;高饲养密度,14 只/平方米)和两种日粮:含 0.5% Tre 的基础日粮和不含 0.5% Tre 的日粮。在开食期/生长期补充 Tre,但不在育成期补充。数据采用双向方差分析法进行分析。我们观察到,单独或联合使用 SD 或 Tre 对初生/生长期的体重增加(BWG)、采食量(FI)和饲料转化率(FCR)均无明显影响。然而,在育成期,高 SD 会降低 BWG(P < 0.001)和 FI(P < 0.05),增加 FCR(P < 0.001)。作为主效应,Tre降低了FCR(P < 0.05),但没有观察到对FCR的综合效应。在整个期间,高 SD 会对体重和饲料报酬率产生负面影响(P < 0.001),而 Tre 会显著降低饲料报酬率,其影响不受 SD 的影响。SD和Tre对空肠形态没有明显影响。高SD不会影响回肠中产气荚膜梭菌的丰度(P > 0.05),但Tre会显著降低其丰度。高SD和Tre都不会改变乳酸杆菌的数量;然而,高SD会增加FPD病变评分,而Tre则没有影响。该研究表明,在开产期/生长期添加Tre可提高育成期的FCR,这可能是通过减少肉鸡体内的产气荚膜杆菌数量实现的。
Trehalose Supplementation Effects on Growth, Intestinal Morphology, Gut Bacteria, and Footpad Dermatitis of Broiler Chickens Reared at High Density.
This study aimed to measure the effects of trehalose (Tre) supplementation on the growth, intestinal morphology, gut bacteria, and footpad dermatitis (FPD) of broiler chickens reared at different stocking densities (SD). Four hundred newly hatched Ross 308 male chicks were randomly allocated to four groups of eight, following a 2 × 2 factorial arrangement in a randomized complete block design using two SDs (normal, 11; high, 14 birds/m2) and two diets: basal with and without 0.5% Tre. Tre supplementation was provided during the starter/grower phase, but not the finisher phase. Data were analyzed using a two-way analysis of variance. We observed no significant effects of SD or Tre, individually or combined, on body weight gain (BWG), feed intake (FI), and feed conversion ratio (FCR) during the starter/grower period. However, high SD decreased both BWG (P < 0.001) and FI (P < 0.05), and increased FCR (P < 0.001), during the finisher period. Whereas Tre reduced FCR (P < 0.05) as a main effect, no combined effect was observed on FCR. Over the total period, high SD negatively affected BWG and FCR (P < 0.001), and Tre significantly reduced FCR, with its effect unaffected by SD. No significant effects of SD or Tre were observed on jejunal morphology. The ileal abundance of Clostridium perfringens (P > 0.05) was not affected by high SD but was significantly reduced by Tre. Neither high SD nor Tre altered Lactobacillus spp. counts; however, high SD increased FPD lesion scores, whereas Tre had no effect. The study showed that Tre supplementation during the starter/grower period improved FCR during the finisher period, possibly by decreasing the abundance of C. perfringens in broiler chickens.
