Effect of light level in sow farrowing room on sows and piglets
The light level in the delivery room We know that there is a big difference between the piglet and the sow in the delivery room temperature, but the light needs to be different between the staff and the sow? The BPEX (UK Swine Commission) knowledge exchange bulletin board Give the answer.
We know that there is a big difference in the delivery room temperature between the piglet and the sow, but does the lighting need to be different between the worker and the sow?
Defra (Department of Environment Food and Rural Affairs, UK) stipulates that supplemental lighting intensity must be at least 40 lux in closed pig houses without natural light and lighting time is at least 8 hours per day. However, under the lux of 40 lux, the staff could not observe the details of the pigs and could not achieve excellent delivery room management. According to the users of the e-net, what level of light is required to achieve the best working efficiency of the staff, what level of light the sow needs, and how can you improve your productivity by adjusting light energy?
Sow needs
Studies have shown that in very bright, 400-500 lux, 16-hour-per-day (8-hour dark) environment, piglet weaning is significantly more important than low illumination, because high light levels make the piglet's feeding frequency and Pigs have increased milk yields.
In addition, studies conducted in dry sows and lactating sows showed short light (250 lux, 8 hours of light per day, 16 hours compared to the case of long light (250 lux, 16 hours of light per day, 8 hours of darkness). In the case of hourly darkness, the level of cortisol in the sow is higher, and cortisol can measure stress levels.
However, free-range sows look for dark areas during nesting to build nests and deliveries. Therefore, it may be necessary to consider increasing the intensity and duration of light after all sows have been delivered in the delivery room. Studies have shown that increased light intensity and time after delivery can promote piglet suckling and sow lactation, thereby increasing weaning weight.
Staff needs
The level of illuminance the breeder needs (lux) depends on the specific work, the details of the observations required, and the hazards and risks of the specific pig house. In general, the minimum required illumination is 200 lux, with an average of 250 to 450 lux. The more detail you need to observe, the higher the illuminance requirement.
In order to increase productivity, measure the lighting of your pig house (lux) today.
Lighting Tips
Installation time switch: This can save energy, but also save labor, otherwise someone will have to remember to turn off the lights every day. Check the light bulb in the pig house to see if it can save energy without affecting the lighting resources. Brush the walls white for more reflection.
1000Hz High Frequency LiDAR System
JRT High Frequency Range LiDAR Sensor is 2021 new product, that's a low-cost tof sensor but High frequency (up to 1000Hz). With 5cm high accuracy, the LiDAR Module can measure 80m.
