Complying with BPEX AI Standard

UK - Seven years since its launch, the BPEX AI Quality Standard continues to focus on improving the reproductive performance of the UK pig industry, says JSR Genetics.

The Standard states that all participating AI centres must demonstrate compliance to 10 major areas including collection, transport, dilution, storage and data recording, to mention just a few.

An additional part of the BPEX Standard also includes sampling semen at random from not only JSR customer farms, but also any other farms supplied by a BPEX approved AI centre. The farmer would be approached and asked to donate a sample of which a BPEX representative would collect and transport in a temperature-controlled storage box to an independent testing laboratory.

The sample would be tested on the date of expiry for motility, semen concentration and bacterial contamination and a report would be produced as seen in Table 1.

At the JSR studs, every collection is tested for motility - which should be at a minimum of 70 per cent on the day of collection, concentration – a minimum of 2.3 billion sperm per dose, and a full morphology check with results being a maximum of 30 per cent abnormalities. The BPEX standard stipulates a morphology check is required on every fourth collection. However, JSR far exceed this requirement by testing every dose supplied to customers.

Further testing takes place on a monthly basis internally in the JSR lab and the findings are reported back to BPEX for them to monitor and record the results.

Every sire line pool is double-checked after dilution by the SP100 Nucleo Counter, which measures the number of sperm per dose of semen, to ensure the semen is at the correct level of concentration. A sample of diluted semen for every batch supplied to a customer is kept at the AI centre and is checked to monitor that the motility is at 60 per cent or above on the date of expiry.
