Management Procedures for Maximising the Mating Programme(82) Managing the mating program for maximum throughput without creating pig flow problems requires good forward planning to achieve consistency.
Calculate the entry to exit time per crate in days e.g.
3 days cleaning time
4 days entry to farrowing
Total = 28 days
In theory therefore each crate could be used 365 ÷ 28 = 13 times per annum. Calculate the actual number. This will indicate the efficiency of use.
2. Fig.3-30 shows a farm example on a weekly basis whereby production is monitored against the cumulative targets. Such a method gives an opportunity to manipulate the system if there is a major loss and compensate for it.
3. For small herds up to 350 sows a circular calendar can provide an excellent and simple visual method. Sows due for culling can be identified by a colour code. In this particular herd summer infertility is a regular phenomenon with increased matings carried out to compensate and disadvantaged sows culled.
4. Another option to maintaining the programme is to serve all sows weaned each week and cull some sows 3 1/2 weeks later to adjust the number of pregnancies to those required.
