Problems solved by technology

In conclusion, the effect of music on animals is still controversial. It should not be considered that playing any type of music on all species will have a good effect, and further research is still needed

Embodiment 1

[0029] Example 1. Method for assessing the effect of musical stimulation on weaned piglets

[0030] 1. Treatment of weaned piglets: test group I (playing classical music Mozart K.448 from 10:00-16:00 every day, with a loudness positioning of 60dB), test group II (playing the original commercial piglet from 10:00-16:00 every day) The background noise recorded in the breeding environment mainly includes mechanical noises such as fans and the noise of pigs, with a loudness of 80dB). The experimental group III is the control group (the daily sound range is 20dB, and no musical intervention is performed on the weaned piglets, but it is the same as the musical stimulation group. , place a music player, but no music).

[0031] 2. The weaned piglets of the above-mentioned three experimental groups were raised in three environmental control rooms with the same structure (sound isolation, consistent temperature and humidity adjustment), and the schematic diagram of the environmental con...

Embodiment 2

[0040] Example 2. Method for assessing the effects of musical stimulation on weaned piglets

[0041] The steps are the same as those of Example 1, except that in test group I (the classical music Mozart K.448 is played from 10:00-16:00 every day, and the loudness is positioned to 70dB), and the test group II (the commercial music is played from 10:00-16:00 every day) The background noise recorded in the original feeding environment of piglets in the pig house mainly includes mechanical noise such as fans and the noise of pigs, with a loudness of 85dB). The same as the music stimulation group, a music player was placed, but no music was played).

[0042] Use the following experiments to verify the effect:

[0043] Randomly select 12 weaned piglets that have undergone an open field test, and after euthanasia by injection of sodium pentobarbital, the brains are quickly removed and placed on ice, and the prefrontal cortex, hypothalamus, amygdala, accumbens and hippocampus tissues...

Abstract

The invention provides a method for evaluating the influence of musical stimulation on weaned piglets, belonging to the field of animal husbandry. The purpose of the present invention is to judge the influence of music on the emotional response of weaned piglets. The invention provides a method for evaluating the influence of musical stimulation on weaned piglets. First, the weaned piglets are treated. One group plays classical music Mozart K.448, and the loudness is positioned at 60-70dB. The noise loudness was 80‑85dB. One group did not perform musical intervention on the piglets, and the sound loudness range was 20‑40dB. The weaned piglets were subjected to an open field test for 5 minutes, followed by a novelty test for 5 minutes, and finally the behavior of all weaned piglets was counted. To explore whether classical music can improve the positive emotions of piglets, and whether environmental background noise has a negative impact on piglets, to provide a theoretical basis for the application of music in production practice to improve animal welfare and health.

Description

technical field [0001] The invention belongs to the field of animal husbandry, and in particular relates to a method for evaluating the influence of musical stimulation on weaned piglets. Background technique [0002] As music continues to deepen in human research, it is increasingly used as a means of environmental enrichment in animal husbandry and veterinary medicine. It has been reported that music, as a regular sound, can enrich the auditory environment of domestic animals and has many benefits in behavioral, emotional and brain nervous system development. Using chimpanzees as research subjects, Videan found that instrumental music increased male-female attachment behavior, and vocal and slow-paced soft music was effective in reducing fighting behavior in male chimpanzees. In addition, music increased play behavior in weaned piglets and reduced aggressive behavior and the degree and number of injuries in weaned mixed herds. Studies of pen-housed and group-housed sows ...
