Home/Laboratories/Producers/Milk analysis

We offer you various milk analyses that can be carried out following milk recording, from a bulk tank sample or as a special analysis. Our laboratories operate year-round, 6 days a week (Monday to Saturday), and your samples sent by standard mail are tested within 24 hours of reception. 

To ensure you get representative results, be sure to follow the right sampling, storage and transportation procedures.

Get the maximum amount of information from each milk sample

Milk recording samples offer the advantage of providing management data that is simple, reliable and affordable for each of your cows. Since we also carry out bulk tank milk analyses, for payment from Les Producteurs de lait du Québec, we are well-equipped to get more useful information from your samples for your herd management.

Individual cow analysis results are provided to you through your herd management reports as well as your Valacta Mobile application. Bulk tank analysis results are published in your extranet on Les Producteurs de lait du Québec's website. 

State-of-the-art analyses

For most of our analyses, we use Fourier transform infrared spectroscopy analyze of the latest generation. These devices offer the advantage of offering a particularly high sensitivity, resolution and data acquisition speed. In fact, they can test over 600 samples per hour. 

Thanks to the evolution of infrared technology, we can now measure with enhanced accuracy, allowing us to develop new analyzes that will profit dairy producers for years to come.

Our milk analyses for your herd management

Milk components: fat, crude protein, true protein and lactose

Whether for individual cows or for your herd, milk component data, especially fat and protein, is the basis for all the decisions you need to make on a daily basis in dairy production.

It is important to note that fat levels vary during a milking session and that the cream separates itself in the bulk tank. Therefore, precautions need to be taken to ensure that the samples sent to the laboratory are really representative.

Results for fat and lactose for individual cows are expressed in kg/100 kg while bulk tank results are expressed in kg/100 litres of milk. You can go from one unit to another by multiplying the kg/100 kg of milk by 1.03.

Results for protein are expressed as kg of crude protein/100 kg of milk for individual cows and as kg of true protein/100 liters of milk for bulk tanks. You can convert between kg crude protein/100 kg to true protein/100 liters first by substracting 0.19 and then by multiplying by 1.03. 

Somatic cell count (SCC)

Somatic cell count is an indicator of both the cows' udder health and milk quality. It is the foundation of any udder health & milk quality management program in a herd.

We offer the total count of somatic cells by cytometry for individual cow samples as well as bulk tank samples. It is important to collect samples with a lactometer to get a milk representation that includes all four quarters. 

Milk Urea Nitrogen analysis (MUN)

Our MUN analysis service allows you to follow and quickly find your cows with non-standard urea levels. Milk urea is a great indicator of how efficiently the ration's protein is used. A highly concentrated urea level indicates a waste of the feed's protein and a high level of nitrogen excretion in the urine. This is a most valuable tool in feed management. 

These analyses are offered for individual cows following a milk recording. 

Bulk tank urea analysis

Bulk tank urea analysis allows to confirm around 15 times per month (at each milk delivery) if your herd's feed is efficiently used. This is an interesting tool to test a new ration between 2 milk recording tests and ensure a better control of your production costs!

However, bulk tank urea analyses alone do not allow to target exactly where adjustments need to be made. It thus needs to be used in combination with individual cow MUN analyses. 

KETOLAB analysis

When the organism draws on their fat reserves as a source of energy, it produces ketone bodies. Their presence in excess indicates that your cows risk suffering from ketosis, a metabolic illness that often occurs at the beginning of lactation as a result of transition period management issues. Our KETOLAB analyses are made on your lactating cows and measure the BHB rate that serves as an indicator. You can then quickly take the action required to solve potential issues with the help of your advisor. 

GESTALAB analysis

Simple, affordable and reliable, GESTALAB allows to detect pregnancy in the milk as soon as 26 days after the service. It is an ELISA test distributed by the company IDEXX Laboratories. A clinical study that has been carried out in collaboration with veterinarians demonstrated that the GESTALAB accuracy was equivalent to that of ultrasounds.

Analyses can be made on samples taken during milk recording or at any time between tests. For the latest option, you first need to request a sampling kit to your Valacta technician, your Ciaq representative or by contacting our customer service. Then, you simply need to send us your samples by mail.

For an accurate test result, it is important to know the date of service and follow the recommended sampling procedures for milk recording. Make sure to provide the date of service so it can be made available in the database. For robot milking herds, we do not accept samples taken from a milking system sampler for our GESTALAB analyses. However, samples taken manually from the cow are accepted.

Paratuberculosis and leukosis detection

Paratuberculosis (or Johne's disease) and leukosis are infectious illnesses that can lead to major financial losses in a herd. Thanks to a prevention and biosafety program established with your veterinarian, we offer the paratuberculosis and leukosis detection in milk, both for the herd (sample and bulk tank) and individual cows. Ask your veterinarian who will advise you on the best detection strategy for your herd.

Our milk quality analysis

Total bacteria count in your bulk tank milk is offered as a special analysis. This analysis requires specialized materials and specific precautions for sampling and transportation. It is important to contact our milk quality laboratory to get the material needed and properly understand the procedures to follow. Also contact our laboratory if you wish to analyze the foreign water rate in your bulk tank milk.
