Description

Technical Field

[0001] This invention relates to the field of pigeon farming technology, and in particular to a method for improving the stress resistance of Hainan pigeons against typhoon disasters. Background Technology

[0002] Located in the tropical monsoon climate zone, Hainan Province receives abundant rainfall, providing favorable conditions for typhoon formation. Furthermore, Hainan's surrounding sea and frequent monsoon activity further fuel typhoon formation and movement, resulting in frequent typhoon impacts. On average, 8-9 typhoons directly make landfall or affect Hainan annually. Typhoons cause sudden changes in the breeding environment, leading to significant stress responses in most pigeons. This results in decreased feeding and absorption, weakened immunity, poor health, impaired reproductive capacity, and reduced resistance to typhoon conditions, leading to high mortality rates. Additionally, slower growth in later stages reduces breeding efficiency. Summary of the Invention

[0003] In view of this, the present invention proposes a method to improve the stress resistance of Hainan pigeons against typhoon disasters, in order to solve the above-mentioned problems. The present invention helps pigeons alleviate the environmental stress brought by typhoons, reduces their stress response, improves their immunity, promotes their later growth, and increases breeding efficiency by formulating suitable pigeon feed.

[0070] Young pigeons, aged 90±10 days, that had just experienced a typhoon, were raised according to the methods described in Examples 1-3 and Comparative Examples 1-5. The pigeon breed was Shiqi pigeon, and the breeding base was Sanjiang Yegeyao Pigeon Breeding Base. In Examples 1-3 and Comparative Examples 1-5, 100 young pigeons of equal numbers (male and female) were fed to each group for 60 days. The mortality rate of the young pigeons was recorded from day 0 to day 60. After the feeding period, the dressing percentage was determined according to the "Terminology and Measurement Statistical Methods for Poultry Production Performance" (NY / T823-2004). The levels of immunoglobulin A (IgA) and immunoglobulin G (IgG) in the post-slaughter serum were measured using an immunoglobulin kit. The results are shown below.

[0071] Table 1 Performance Indicators of Meat Pigeons

[0072] Example 1 0 91.05 Example 2 2 90.78 Example 3 1 90.64 Comparative Example 1 6 89.13 Comparative Example 2 9 87.27 Comparative Example 3 13 83.16 Comparative Example 4 11 85.39 Comparative Example 5 4 88.50

[0073] The above results indicate that the feeding methods described in Examples 1-3 of this invention can effectively reduce the stress of pigeons to typhoons, improve their adaptability to the environment, effectively enhance their immunity, promote the absorption and utilization of nutrients, promote growth and development, effectively reduce mortality, and result in a higher slaughter rate of pigeons after 60 days of feeding. Compared with Example 1, Comparative Example 1 changed the proportion of feed ingredients; Comparative Example 2's feed did not contain lignans, kaempferol, or vitamin C ethyl ether; Comparative Example 3's feed did not contain plant additives or compound probiotics; Comparative Example 4 did not feed grit; and Comparative Example 5 changed the raw material formula and dosage of disinfectant. These changes led to a decrease in the efficiency of nutrient absorption and utilization in the feed, poor adaptability after typhoons, reduced growth and stress resistance, and thus affected the performance of the pigeons.

[0075]

[0076]

[0077] The above results indicate that the feeding methods described in Examples 1-3 of this invention can promote the increase of immunoglobulin levels in pigeon serum, thereby enhancing the pigeons' immunity, effectively promoting the absorption and utilization of nutrients, improving their resistance to typhoons, and reducing stress responses. Compared with Example 1, Comparative Example 1 changed the feed ingredient ratio; Comparative Example 2's feed did not contain lignans, kaempferol, or vitamin C ethyl ether; Comparative Example 3's feed did not contain plant additives or compound probiotics; Comparative Example 4 did not feed grit; and Comparative Example 5 changed the raw material formula and dosage of the disinfectant, all of which affected the immunoglobulin levels in pigeon serum. Furthermore, feeding young pigeons aged 100-180 days using the methods described above can also effectively improve their stress resistance to typhoon disasters, resulting in high breeding efficiency.

[0078] In summary, this invention, by using suitable carvacrol, Sichuan pepper extract, and areca nut extract as disinfectant raw materials to disinfect pigeon lofts after a typhoon, can reduce the spread and infection of pathogens, regulate the appropriate ambient temperature of the pigeon loft, reduce stress response in pigeons, improve the immunity of pigeons by adjusting and optimizing the feed formula and grit formula, promote the digestion and absorption of feed nutrients, enhance resistance to pathogens, improve growth efficiency after a typhoon, effectively alleviate the stress pressure on pigeons caused by typhoons, and improve the resistance of pigeons to typhoon disasters.
