Introduction.
The environment of the pig house is an important factor affecting the growth, health and performance of pigs. A good pig house environment can not only improve the survival rate of pigs and reduce the occurrence of diseases, but also improve the growth rate and feed conversion rate of pigs, thereby increasing the economic benefits of breeding. Therefore, the evaluation criteria for the pig house environment are particularly important. This paper will focus on the evaluation criteria of the pig house environment, and analyze it in combination with actual data.
Environmental evaluation standards for pig houses.
1.Temperature: The temperature in the barn is essential for the growth and health of the pigs. The suitable temperature range varies from season to season, but in general, the suitable temperature is 20 -25 in winter and 25 -30 in summer. Temperatures that are too high or too low can lead to slowed growth, loss of appetite, and disease susceptibility.
2.Humidity: Humidity is also an important factor in the pig house environment. Excessive humidity can cause the air to become humid, providing conditions for the growth of bacteria and mould, which can cause diarrhea and respiratory diseases in pigs. The suitable humidity range should be between 50% and 60%.
3.Air quality: The air quality in the barn has a direct impact on the health of the pigs. High concentrations of harmful gases such as ammonia and hydrogen sulfide can cause damage to the respiratory system of pigs and cause respiratory diseases. Therefore, it is essential to keep the air in the barn fresh and reduce the concentration of harmful gases.
4.Light: Light has an important impact on the growth and reproduction of pigs. The right amount of light, light intensity, and light frequency can help pigs grow and health, while too much light can cause reproductive problems.
Practice Data & Assessment.
To evaluate the actual effects of the barn environment, we conducted an experiment. In the experiment, pigs of the same batch and the same age were selected and divided into two groups and raised in two different pig houses. The environmental conditions of one pig house meet the above evaluation criteria, while the environmental conditions of another pig house have some problems. The experiment lasted for 6 months, and the quality of the pig house environment was evaluated by regularly collecting samples of air, manure, feed and other samples in the pig house for testing and analysis.
The experimental data showed that the concentration of ammonia, hydrogen sulfide and other harmful gases in the pig house that met the evaluation standards was significantly lower than that in the pig house that did not meet the standards. In addition, the humidity, temperature and air quality in the pig house that meet the evaluation standards are also more suitable, which is conducive to the healthy growth of pigs. In the substandard barn, the incidence of diarrhoea and respiratory diseases in the pigs was significantly higher than that in the substandard barn due to the poor environmental conditions.
In terms of light, the light time, intensity and frequency in the pig house that meet the evaluation standards are more suitable, which is conducive to the growth and reproduction of pigs. Too long or too little light in a non-compliant barn can adversely affect the growth and reproduction of pigs.
In summary, the data show that a good pig house environment is of great significance for improving the growth rate of pigs, reducing the occurrence of diseases and improving feed conversion rate. At the same time, a good pig house environment can also improve the economic and social benefits of breeding. Therefore, farmers should pay attention to the maintenance and management of the pig house environment to ensure that the pig house environment meets the above evaluation standards, so as to improve the breeding efficiency and reduce the risk of disease.
Conclusions and recommendations.
A good pig house environment is a key factor in ensuring the healthy growth and performance of pigs. Through the evaluation and management of environmental factors such as temperature, humidity, air quality and light, the environmental quality of the pig house can be effectively improved. At the same time, farmers should regularly monitor and maintain the pig house environment to ensure the suitability of environmental conditions. In addition, farmers should also pay attention to the application of new technologies and methods in improving the environment of pig houses to improve breeding efficiency and management level.
In short, the evaluation standard of the pig house environment is an important means to ensure the healthy growth of pigs. Through the practical data and evaluation, we can see that the pig house environment that meets the evaluation criteria is of great significance for improving the efficiency of breeding and reducing the risk of disease. Therefore, we call on the majority of farmers to pay attention to the maintenance and management of the pig house environment to achieve better economic and social benefits.
