Data sharing - Broiler Digesta Collection Methods.xlsx

Data collection involved monitoring bird performance (BW, FI, FCR, and mortality) from day 1 to day 18, constituting the non-experimental phase. The experimental diet was then introduced on day 18 and continued until day 21. Feed intake data were calculated during this period as well. On day 21, ileal content was collected from all birds. Individual ileal samples were pooled by cage, lyophilized, and sent to a laboratory for further analysis, along with corresponding diet samples. Laboratory analyses included assessing amino acid and TiO2 content in both the digesta and diet samples.

本数据集的收集涵盖了第1日至第18日期间家禽生产性能的监测，包括体重（Body Weight, BW）、采食量（Feed Intake, FI）、料重比（Feed Conversion Ratio, FCR）及死亡率，该阶段为非实验期。实验日粮于第18日开始饲喂，并持续至第21日，此期间同样采集并计算采食量数据。第21日时，采集所有家禽的回肠内容物。将单只家禽的回肠样本按笼组进行混合，经冷冻干燥处理后，与对应的日粮样本一同送至实验室开展后续分析。实验室分析内容包括测定食糜与日粮样本中的氨基酸及二氧化钛（TiO2）含量。
