Ideal mating time
The optimal fertilization of a sow depends on several factors, among them, mating in a specific moment of the oestrus.
Trouble-shooting herd fertility problems
Let us assume that the expected farrowing rate and live-born litter sizes are 90% and 12.5, respectively, but that current performance is 82% and 11.3, respectively. This means that too many sows are bred but failing to farrow and those that farrow are having fewer pigs.
Planning weaning (I): How many sows should I wean?
