Description

Technical Field

[0001] The utility model belongs to the technical field of environmental monitoring, and more specifically, relates to a pig feed production and storage environment monitor. Background Art

[0002] Pig feed typically consists of protein feed, energy feed, roughage, green feed, silage, mineral feed, and feed additives. It can be categorized into complete feed, concentrate feed, and premix feed. A complete feed is a compound feed consisting of protein feed, energy feed, roughage, and additives and can be fed directly to the pigs. Concentrate feed is a premix of protein ingredients and additives, requiring the addition of energy feed during feeding, offering the advantage of convenience. Premix feed is an intermediate feed product made by uniformly mixing one or more trace components with a diluent or carrier in the required proportions.

[0003] After pig feed is processed, excess feed is typically stored in silos. Large quantities of pig feed are often piled up in warehouses for long-term storage. First, avoid direct sunlight: Sunlight exposure can reduce the nutritional value of pig feed and even produce harmful substances. Therefore, pig feed should be stored in a cool, shady place, away from direct sunlight. Second, prevent moisture and ensure ventilation: Pig feed is hygroscopic and should be stored in a dry, well-ventilated area to prevent moisture-induced mold and deterioration. Warehouses should be located in dry, well-ventilated, and cool locations, with moisture-proof floors and walls. Third, control humidity and temperature: Pig feed should be stored in an environment with a relative humidity below 70%, and the moisture content should not exceed 12.5%. Long-term storage is possible if the ambient temperature is kept below 15°C and the relative humidity below 80%. The storage temperature should be kept between 15°C and 25°C, avoiding the effects of high or low temperatures.

[0004] Currently, both pig feed manufacturers and pig farms store feed in dry, open spaces, away from direct sunlight and drafts. However, the ambient temperature and humidity are not monitored. Consequently, during rainy seasons, pig feed can easily spoil. Pigs that eat spoiled feed can become ill, requiring medical treatment and experiencing a sharp drop in weight, resulting in significant losses for the farm. Utility Model Content

[0048] Temperature: Pig feed storage should be kept within a range of 10-25°C to avoid temperatures that are too low or too high, which can lead to fatty acid oxidation and vitamin degradation in the feed. High temperatures (e.g., above 15°C) stimulate enzyme activity, accelerating the decomposition of nutrients while promoting the growth of microorganisms and pests, leading to heat and mold in the feed. Experiments have shown that when the ambient temperature is below 15°C, pests become inactive and microbial growth is inhibited.

[0049] Humidity: Humidity in pig feed storage rooms should be kept below 60% to prevent moisture and mold. Excessive humidity causes the feed to absorb moisture, promoting the growth and reproduction of mold, which consumes and decomposes nutrients in the feed, affecting feed quality and pig health. Feed moisture content should be reduced to below 13%, which reduces the risk of insect and mold growth even when stored at higher temperatures.

[0050] Ventilation: The pig feed storage room should have good ventilation conditions to keep fresh air circulating and reduce the growth of odor or mold. Poor ventilation will cause moisture and harmful gases in the air to accumulate, affecting the preservation of feed.

[0051] Specific measures:

[0052] Control temperature: The temperature of the storage room can be adjusted by using air conditioning or refrigeration equipment to ensure that it is within the appropriate range.

[0053] Control humidity: Use a dehumidifier or open windows regularly to ventilate the room to reduce humidity and keep the environment dry.

[0054] Ventilation: Ensure that the storage room has good ventilation facilities and regularly inspect and maintain ventilation equipment.
