Scientific research shows that although pigs can only see blue and green light, they are not very sensitive to light color and color temperature, but they have a greater impact on light intensity and light time, especially for pigs grown in different periods, which directly affects the rearing The slaughter time and economic benefits of the pig farm. According to this principle, it is a question we have to consider. Making full use of light to raise pigs has so many benefits. Then, the application of led lamps in pig farms is more important.
1. The effect of LED lamp light on piglets.
Mainly affect the immune function and material metabolism of piglets
Studies have shown that after 16 hours of light treatment per day during pregnancy, the immune status of piglets produced by sows at the age of 14 days is better than that of the 12-hour light group. The illumination intensity increased from 10Lux to 60Lux and then 100Lux, the incidence of piglets decreased by 24.8%～28.6%, the survival rate increased by 19.7%～31.0%, the daily weight gain increased by 0.9kg～1.8kg, and the light intensity increased to 350Lux. The effect was better than that of 60Lux. Poor, it is recommended that the light intensity of nursery pigs be 50 Lux ~ 100 Lux. In the conservation phase, it is recommended to use a heating plate or a non-light heating lamp. The traditional heating lamp produces a large amount of non-heating visible light waves during use, which wastes a lot of energy. Can use 3000k-4000k color temperature led tube.
2. The impact of LED lamp light on sows.
Extended light can promote embryonic development and sow reproductive system development
Because light can stimulate the hypothalamus of the back sow to reduce the secretion of melatonin, promote the release of gonadotropin-releasing hormone, and accelerate the maturation of the sow's follicles. Studies have shown that ensuring 16 hours of light a day can make Rongchang pigs 18.5 days of puberty earlier, and the number of litters will increase by 2.8. In addition to the light time, we must also pay attention to the light intensity. Compared with the light intensity of 40 Lux, the light intensity of 200 Lux and 1000 Lux cannot reduce the secretion of melatonin in the sow.
The light intensity in the breeding sow house increased from 6 Lux to 8 Lux to 70 Lux to 100 Lux, the litter size, newborn weight and litter weight, average daily gain, and weaning litter weight increased by 4.5% to 8.5%, 4.5% to 16.7% ( 0.7 kg to 1.6 kg), 5.6%, 5.1% to 12.2%. The study pointed out that compared with 8 hours of light per day, 16 hours of light per day during lactation can significantly increase the number of 21-day-old and weanable pigs. This may be because long light can increase the number of lactations of piglets and the lactation of sows. There is no significant difference.
It is recommended that the appropriate light intensity for the reserve/bringing sows is about 100 Lux, and the light time is 14 to 16 hours per day. If the illuminance is required to change, our Langte provides dimming LED tubes, which can adjust the brightness of the light as needed.
3. The effect of LED lamp light on fattening pigs.
It is recommended that the light intensity for growing and finishing pigs is generally 40 Lux ~ 50 Lux.
The illumination time is within the range of 12 hours to 24 hours. The shorter the illumination time, the more conducive to improving the growth performance of fattening pigs, reducing the feed-to-meat ratio and morbidity, and reaching a significant level. The fattening pigs were fed under two light periods (70 Lux, light period: 14: 10 and 8: 16 respectively in the dark period). The results showed that the feed and meat ratio of fattening pigs in the long light period (4.3) Very significantly lower than the short photoperiod (5.21). This shows that for growing and finishing pigs, the light time should not be too long, and the 8-hour light-to-meat ratio should be higher than 14 hours, so the light time should not exceed 12 hours as much as possible. That is, in order to grow quickly, try to let the pigs rest under low illumination and low illumination to grow fat. In order to shorten the time to market and create economic benefits.
4. how to choice led tube?
Generally, the area of pig farms is relatively large, and the LED tube illuminates a large area, which is cost-effective. It is an ideal light source. However, pay attention, try to use waterproof LED tubes, the main reason is the humid environment of the pig farm. In this way, while satisfying the lighting, it will not affect the life of the lamp tube. After all, such an environment is still relatively corrosive. Electronic products are afraid of humid and corrosive environments.
Ultraviolet light tube, this kind of light tube can disinfect the pig farm. Because it is physical disinfection, it does not pollute the environment, so it is an ideal sterilization and disinfection tool. There are three types of 40w ultraviolet lamp 1.2m, 30w ultraviolet lamp 0.9m and 20w ultraviolet lamp 0.6m, which can be reasonably selected according to the size of the area.
General lighting: You can choose according to the color temperature. The color temperature is low, it looks warm; the color temperature is high, it looks cold. CRI is generally 80ra. The power and length of the led tube can be produced as required.
