Embodiment 1
[0027] This embodiment provides a method for alleviating the quality decline caused by broiler transportation stress, including:
[0028] 1. Choose Aiboyijia broiler chickens, and randomly divide them into 3 treatments, each treatment has 7 replicates, and each replicate has 8 chickens.
[0029] Treatment groups include: control group, fed with basal diet without transportation;
[0030] Transport group, fed basal diet and carried out 3h transport on the 42nd day;

The invention relates to the technical field of animal feed, in particular to application of saccharomyces cerevisiae in relieving chicken quality decline caused by transportation stress. It is found that in the broiler chicken transportation process, the problem that the quality of chicken meat is reduced due to emergency transportation can be remarkably relieved by adding the saccharomyces cerevisiae into the chicken feed. For example, in the transportation process of broiler chickens, 500-2000 mg / kg of saccharomyces cerevisiae is added into chicken feed, so that the technical effects of remarkably improving the total antioxidant capacity of pectoralis muscles and leg muscles, reducing the content of malondialdehyde in the pectoralis muscles and the leg muscles, improving the content of glutathione peroxidase in the leg muscles, or reducing the mRNA expression quantity of avUCP of the pectoralis muscles and the leg muscles and the like can be achieved. and a feasible scheme is provided for solving key problems of broiler chicken production.
Description
technical field [0001] The invention relates to the technical field of animal feed, in particular to the application of Saccharomyces cerevisiae in alleviating the decline in chicken quality caused by transportation stress. Background technique [0002] Transportation stress refers to a series of instinctive discomfort reactions produced by the animal body under the comprehensive action of stressors such as fasting / restricted feeding, environmental changes, bumps, and psychological stress during transportation. However, with the continuous advancement of the intensive farming process, the process of broiler chickens from the farm to the slaughterhouse inevitably suffers from transportation stress. Studies have shown that under transportation stress conditions, animals will show shortness of breath, rapid heartbeat, fear and anxiety, etc., causing severe stress to broilers. Physiologically, it is mainly manifested as an increase in plasma corticosterone levels and a decrease ...
