Beef cattle

I’ve been working with the British meat grading industry for 6 years now, and earlier this month, I also had the opportunity to visit Switzerland for the second time to work on ultrasound meat grading for sheep. This week, I flew to Ames in Iowa, to see how the CUP Lab are running their ultrasound technician training programme, and learn how the Americans are collecting data on intramuscular fat percentage (IMF%) in cattle. There are other data processing laboratories in the USA, but it was Quality Assurance Manager Emily’s willingness to discuss her......

Dog breeding

New regulations announced in 2016 are coming into force this Monday, the 1st of October 2018. The catchy title for this new legislation is the ‘Animal Welfare (Licensing of Activities Involving Animals) (England) Regulations 2018.’ This act repeals both the Breeding of Dogs Act 1991 and the Breeding and Sale of Dogs (Welfare) Act 1999 and also revokes the Sale of Dogs (Identification Tag) Regulations 1999 and Breeding of Dogs (Licensing Records) Regulations 1999. Lack of knowledge regarding this legislation is not a defense in the case of non-compliance – yet, with 4......

canine pregnancy

The publication date of the book ‘Ultrasound for Canine Pregnancy Scanning’ is fast approaching, and with that, some final touches and triple-checking research into some of the remaining puzzles of ultrasound imaging. Those with scanning experience already will know very well how bone appears on ultrasound. Not only does it return very strong reflections, making it appear bright white, but solidified bone also affects imaging of surrounding tissue, casting a shadow behind it. This is due to both its high reflectivity (and why it’s so reflective is explained thoroughly in the book) but......

A weekend in Switzerland

The Swiss Sheep Society (Schweizerischer Schafzuchtverband or SSZV) have just introduced an ultrasound machine for the first time, supplied by Vet Image Solutions in Bromley. Using a linear probe, they will begin collecting data on fat and muscle depth in sheep across Switzerland. I visited the society on Saturday, and we spent the day going through the controls of their new system – particularly the importance of frequency, depth, gain and focal point. Optimising image resolution is particularly important for meat grading work, where measurement accuracy is so important (you can read......

Lamb meat grading

Fat and muscle depth have been measured using ultrasound in cattle, pig and sheep meat grading work for well over two decades. In sheep, measurements are most commonly taken at the 12th-13th ribs, although using the third to forth lumbar vertebrae has been shown by some to give greater correlation with actual carcass measurements (Thériault et al., 2009). Signet Breeding Services are UK leaders in such work, and using tailor-made ultrasound equipment from Bromley-based Vet Image Solutions, they also favour this site. Obtaining these measurements involves a steep learning curve, but once......
