Abstract

Objective: The effect of feeding yeast-fermented feed in various forms on broiler growth performance and bone mineralization was studied.

Materials and methods: Initially, a corn-soy-based diet was formulated and fermented in anaerobic conditions at 28°C in laboratory space for 48 h with yeast (2.0%) and moisture (50%). Afterward, the 150 newly hatched Arbeor Acres commercial broiler chicks were divided into 5 dietary groups (30 chicks, 6 cages, and 5 birds per cage). Each group received one of the following formulated and fermented diets: dry feed (DF), moist feed (MF), yeast-added dry feed (Y-DF), yeast-added moist feed (Y-MF), or yeast-fermented moist feed (YF-MF). Water and feed were supplied ad libitum. Six birds per group were slaughtered at age 37 for the determination of carcass traits and tibia ash.

Results: Fermentation improved crude protein from 20.7% to 22.8% but declined crude fiber from 7.9% to 6.3% in the YF-MF group compared to the DF group. High body weight gain was recorded in 771, 830, and 992 gm in the MF, Y-MF, and YF-MF groups, respectively, compared to the DF (762 gm) group (p < 0.01). The feed conversion ratio was better in the Y-MF (1.57) and YF-MF (1.57) groups than in the DF (1.75) group. Feeding a fermented, moist diet resulted in improved carcass yield (69%) in the YF-MF group. Bone mineralization expressed a better tibia ash percentage (35% from 30%) in the YF-MF group compared to the DF group.

Conclusion: Therefore, YF-MF enhanced the quality of feed and improved growth, carcass weight, and bone mineralization in broiler.

面包酵母发酵湿润饲料对肉鸡生长和骨骼矿化的影响

目的：研究不同形式的酵母发酵饲料对肉鸡生长性能和骨骼矿化的影响：研究不同形式的酵母发酵饲料对肉鸡生长性能和骨骼矿化的影响：首先，配制以玉米-大豆为基础的日粮，并在28°C的实验室厌氧条件下用酵母（2.0%）和水分（50%）发酵48小时。然后，将 150 只刚孵化的 Arbeor Acres 商品肉用雏鸡分成 5 个日粮组（30 只雏鸡、6 个笼子、每个笼子 5 只鸡）。每组分别饲喂以下一种配方和发酵日粮：干饲料（DF）、湿饲料（MF）、酵母添加干饲料（Y-DF）、酵母添加湿饲料（Y-MF）或酵母发酵湿饲料（YF-MF）。水和饲料自由供给。每组 6 只鸡在 37 日龄屠宰，测定胴体性状和胫骨灰分：与 DF 组相比，发酵使 YF-MF 组的粗蛋白从 20.7% 提高到 22.8%，但粗纤维从 7.9% 下降到 6.3%。与 DF 组（762 克）相比，MF 组、Y-MF 组和 YF-MF 组的增重分别为 771、830 和 992 克（p < 0.01）。Y-MF 组（1.57）和 YF-MF 组（1.57）的饲料转化率优于 DF 组（1.75）。饲喂发酵湿润日粮提高了 YF-MF 组的胴体产量（69%）。与 DF 组相比，YF-MF 组的胫骨灰分百分比（从 30% 提高到 35%）更高：因此，YF-MF 提高了饲料质量，改善了肉鸡的生长、胴体重量和骨矿化。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
