Colostral immunity is very important. It is vital that piglets receive sufficient colostral uptake within the first 6 h. Colostrum intake should continue during the next 18 h. Cross-fostering should cease after 24 h as then there is a danger of a further spread of microorganisms. Ideally the immunity status of a group of piglets is fixed after 24 h. In many instances teeth clipping is unnecessary. It is vital to keep clippers as sterile as possible. Ideally several pairs should be on the go at any one time, so that the spare pairs can be stored in disinfectant. Needles for iron injections and any vaccinations should be regularly changed. One per litter should be considered as a minimum. Sows/gilts should be given a good wash and treated for parasites before entering the farrowing house. Parasitic burdens in the sow result in the animal becoming disadvantaged or in poor condition. In this state its colostrum levels might be compromised, having a detrimental effect on the piglets.
