Description

[0001] The present invention relates to the technical field of poultry farming, and specifically to a method for restoring the feed intake of meat pigeons after a typhoon disaster. Background Art

[0002] In the southern part of China, typhoons often occur or are affected by typhoons. The accompanying wind and rain weather of typhoons cause scares and injuries to meat pigeons. A single typhoon attack will cause direct economic losses to farmers. Therefore, under special climates, especially restoring the normal farming of meat pigeons after a typhoon is very important. Dietary supplementation is a way to enhance one's own immunity and resistance through the nutrients in food, and the physical constitution can be improved through dietary supplementation. Therefore, high-quality meat pigeon feed with dietary supplementation effects is particularly important. The Chinese herbal medicine Dendrobium contains various bioactive components such as alkaloids, polysaccharides, and amino acids, and has effects such as anti-inflammatory, anti-tumor, antioxidant, anti-fatigue, blood sugar lowering, and immune regulation. The effect of dietary supplementation with Dendrobium is better than taking medicine. At present, there is little research on restoring the feed intake of meat pigeons after a typhoon disaster, and most of the research on meat pigeons focuses on the farming methods of meat pigeons in normal growth environments and optimized growth environments. For the typhoon climate, there are mainly the following problems in meat pigeon farming: First, there is a lack of feeding methods and coping methods under stress conditions; second, there is a lack of preparation and supply of special feed and special drinking water under stress conditions. The previous farming methods and feed raw material ratios are not applicable to farming under special conditions. Therefore, in the context of quickly resuming production and farming after a typhoon disaster, a method for restoring the feed intake of meat pigeons after a typhoon has application prospects.

[0052] A total of 160 meat pigeons were randomly selected and divided into 3 groups in the experimental group (Experimental Groups 1 - 3) and 5 groups in the control group (Control Groups 1 - 5), with 20 pigeons in each group. Experimental Groups 1 - 3 were raised using the methods of Examples 1 - 3 of the present invention, and Control Groups 1 - 5 were raised using the methods of Comparative Examples 1 - 5. The number of dead pigeons in each group was counted on the 3rd day and the 6th day respectively, and the mortality rate was calculated, as shown in Table 1. The statistical results showed that both the 3 - day mortality rate and the 6 - day total mortality rate of the meat pigeons raised using the methods of Examples 1 - 3 decreased. The 6 - day total mortality rate of the meat pigeons raised using the methods of Examples 1 - 3 ranged from 10% to 15%, while the 6 - day total mortality rate of the meat pigeons raised using Comparative Examples 1 - 5 ranged from 20% to 25%.

[0055]

[0056] The 20 meat pigeons in each group of Experiment 1 were screened, and the meat pigeons with a birth age between 20 and 22 days were selected for feed intake statistics and body weight measurement experiments. The total feed intake and body weight on the 0th day, 3rd day, and 6th day were recorded. The average daily feed intake within 6 days is shown in Table 2.

The statistical results in Table 3 showed that the average body weight gain of the meat pigeons raised using the methods of Examples 1 - 3 on the 3rd day and the 6th day was higher than that of Comparative Examples 1 - 5. The average body weight gain of the meat pigeons raised using the methods of Examples 1 - 3 on the 3rd day ranged from 35 g to 41 g, and the average body weight gain on the 6th day ranged from 80 g to 87 g, which was significantly higher than that of Comparative Examples 1 - 5.
