低温干燥对肉鸡和去盲肠蛋鸡排泄物中含氮化合物和肌醇磷酸的影响Effect of low‐temperature drying on the nitrogenous compounds and inositol phosphates in broiler chickens and cecectomized laying hen excreta 总氮基于凯氏法使用格哈特Gerhardt公司Vapodest 50s全自动凯氏定氮仪测定 氨氮使用使用格哈特Gerhardt公司Vapodest 50全自动蒸馏滴定凯氏定氮仪测定 Total N and ammonia in excreta were measured without further processing. For all other analyses, the excreta were freeze dried and ground to a powder using a vibrating disc mill (Fritsch Pulverisette 9; Fritsch GmbH). Kjeldahl digestion was performed on the Vapodest 50S analysis system (C. Gerhardt GmbH & Co. KG). Ammonia was measured by steam distillation and titration by using the Vapodest 50 analysis system (C. Gerhardt GmbH & Co. KG) as described by Hofmann et al. (2019). The official methods for nutrient analyses in Germany (Verband Deutscher Landwirtschaftlicher Untersuchungs- und Forschungsanstalten 2007) were followed for dry matter (no. 3.1), total N (no. 4.1.1), crude ash (no. 8.1), crude fat (no. 5.1.1) and crude fiber (no. 6.1.1) content of the diets. The diets were ground in a centrifugal mill and passed through a 0.5 mm sieve (Retsch GmbH, Hann, Germany) prior to analyses.
