Abstract

Technological stresses in the poultry industry directly affect the broiler-chicken’s performance and the production intensification. The technological stress factors affect the metabolic pathways occurring in the chicken’s body. The objective of the survey was to assess the efficiency of the feed additive used for broiler chickens in the technology-related stress environments in the broiler chicken industry. The feed additive used for the broiler chickens reared in the preslaughter period could allow us to maintain their productive performance due to decreasing the technological load on the bird’s body. This was proven by increasing the average daily liveweight gain, the absolute liveweight, the welfare benefit, the meat yield, and the gross revenue in the chickens of the experimental group by 0.7, 2.3, 1.5, 13.4, and 49.2%, respectively. The 22.54, 22.5, and 5.07% higher contents in serum total protein, calcium, and phosphorus, respectively, along with the 6.12, 2.22, and 7.05% lower levels of total lipids, cholesterol, and glucose, respectively, were recorded in the experimental group of broiler chickens compared to that in the control.

抗应激饲料添加剂在肉鸡生产中的效率

摘要

家禽业的技术压力直接影响肉鸡的性能和生产集约化。技术压力因素影响鸡体内发生的代谢途径。该调查的目的是评估在肉鸡行业中与技术相关的压力环境下，用于肉鸡的饲料添加剂的效率。在屠宰前饲养的肉鸡所用的饲料添加剂由于降低了禽类身体的技术负荷，可以使我们保持生产性能。实验组鸡的平均日增重，绝对活重，福利，肉产量和总收入分别增加了0.7％，2.3％，1.5％，13.4％和49.2％，这证明了这一点。22。
