Egg Production, Egg Quality, Blood Profiles, Cecal Microflora, and Excreta Noxious Gas Emission in Laying Hens Fed withFenugreek (Trigonella foenum-graecum L.) Seed Extract

摘要

This study was designed to investigate the effects of dietary fenugreek seed extract (FSE) supplementation on egg production, egg quality, blood profiles, cecal microflora, and excreta noxious gas emission in laying hens. A total of 384 laying hens (26-weeks old, Hyline-brown) were fed three different levels of FSE (0, 0.05, and 0.1%) in a cornsoybean diet for 6 weeks. The inclusion of FSE in the laying hen diet did not affect egg production, feed intake, or feed conversion among treatments; however, egg weight, eggshell breaking strength, eggshell thickness, and yolk color increased in FSE-fed groups (linear, P.
