ABSTRACT The objective of the study was to determine the effect of probiotic preparations Pro-Biotyk EM-15 and EMFarma™ and sex on morphometric characteristics of the digestive system and leg bones, and caecal microflora in Ross 308 broiler chickens. One-day chicks were distributed into two groups in two rooms (control, experimental). Each facility contained 9000 Ross 308 chicks and was divided into four compartments. A total of 48 Ross 308 broiler chickens aged 42 days were evaluated, including 12 males and 12 females which received no probiotics, and 12 males and 12 females supplemented with EM preparations. At the age of 42 days, EM supplemented broilers had significantly greater total intestine length, higher intestine–body length ratio and higher proventriculus percentage in body weight. Regardless of the treatment, males exhibited higher body weight, duodenum, jejunum, ileum lengths and total intestine length, higher intestine–body length ratio and spleen weight, and lower duodenum diameter and liver percentage. The group × sex interaction was significant for smallest breadth of the corpus of femur bone and greatest diagonal of proximal end, smallest breadth of the corpus and smallest breadth of distal end of tibia bone.

益生菌制剂 (EM) 和性别对肉鸡消化系统、腿骨和盲肠微生物群落形态特征的影响

摘要 本研究的目的是确定益生菌制剂 Pro-Biotyk EM-15 和 EMFarma™ 以及性别对 Ross 308 肉鸡消化系统和腿骨以及盲肠微生物群落形态特征的影响。一天的小鸡被分成两组在两个房间（对照，实验）。每个设施包含 9000 只罗斯 308 雏鸡，并分为四个隔间。总共评估了 48 只 42 日龄的 Ross 308 肉鸡，其中 12 只雄性和 12 只雌性未接受益生菌，12 只雄性和 12 只雌性补充了 EM 制剂。在 42 日龄时，添加 EM 的肉鸡具有显着更长的总肠长、更高的肠-体长比和更高的体重百分比。不管治疗如何，雄性表现出较高的体重、十二指肠、空肠、回肠长度和总肠长，较高的肠体长比和脾重，以及较低的十二指肠直径和肝脏百分比。股骨骨体最小宽度和近端最大对角线、骨体最小宽度和胫骨远端最小宽度的组×性别交互作用显着。
