Pig Farming: Hot Useful Tips

[Henlus]

For piglet diarrhea, here are some info I got after some research:

weaning age also contribute. Experts recommend 26-28 days or more as oppose to 21 days so that the piglets will develop strong Immune system and gastro-intestinal tract.

Other contributing factors are housing, population density, parity segregated production and the feeding regimen after weaning.

Maintain 26–28 °C. Cold conditions will make post weaning diarrhoea more severe. Feeding weaners 2x per day with a restricted amount of feed is bad. Rather feed 3x or more per day with or without restricting feed. Pelleted feed and inadequate feeder space also contribute.

Reducing the level of soybean meal in the feed reduces the severity and frequency of PWD (post weaning diarrhea) and oedema disease. Adding organic acids, probiotics, prebiotics, or  zinc oxide (2400–3000 ppm in feed or zinc methionine (ZnM) at 500 mg/kg feed) and reducing feed protein content also help. Note that giving higher level of zinc will increase the diarrhoea incidence.

Good organic acids include citric, acetic, fumaric, lactic, propionic, benzoic and formic acids
