1, cut off the umbilicus. Cut off the umbilical cord and placenta when leaving 10 to 15 cm long, 2 cm from the abdomen for banding and disinfection to avoid infection.
2, eat early, eat enough colostrum. The interval between birth and the first dose of colostrum does not exceed 2 hours, and is eaten every 1 hour. Gradually it is extended to 2 hours. After 3 days, the sows are allowed to breastfeed.
3, fixed nipples. Within 2 to 3 days after childbirth, artificially fixed the teat, and put the weak piglet in the front middle section so that the entire litter of piglets develops evenly and neatly.
4, to strengthen the insulation, antifreeze and pressure. The suitable ambient temperature is 25 °C ~ 28 °C.
5, timely iron and selenium. Iron and selenium are essential elements for hematopoiesis and prevention of nutritional anemia. The piglets need about 7 milligrams a day for growth and only 1 milligram for breast milk, but supplementation should not be excessive. Within 3 days after birth and before weaning, piglets are injected intramuscularly with ferritin, iron-rich or 0.2% sodium selenite 1-1.5ml to supplement calcium, iron, zinc and other trace elements needed by piglets to enhance immunity. Reduce diarrhea in piglets.
6, cut teeth and broken tail. On the first day of birth, teeth and tails are cut off to avoid biting and mutual attacks.
7, are nest foster care. The piglets were mixed before the nest was raised and raised. The whole body of the piglets was wiped with the milk of the “nanny†and mixed at night so that the breeding sows could not distinguish the self-produced and fostered piglets.
With long range distance sensor with digital output, you can measure and monitor distances intergrated to your arduino, raspberry pi etc. The Laser Distance Sensor low cost is a competitive measure sensor, can measure from 3cm to 40m, 100m, max to 150m with +-1mm~+-3mm accuracy. Also, other requirements can be customized, like distance sensor analog output,long range ir sensor. We will give you full technical support when you testing our long distance sensor.
