ANALYSIS
Discover our analysis and our laboratory
We invite you to come and discover our laboratory located in Marcy l'Etoile: you will discover the route of your samples and the realization of analysis that you have entrusted to us.
A simple telephone call to NBVC and we will be happy to arrange this visit for you.
Our technicians perform every day dozens of blood and urine tests.
These analyses are both descriptive of a deteriorated situation: for instance, the exploration of blood parameters of a downer cow, Calcium, Magnesium, Thyroxine, Haptoglobine But they may also be predictive of a situation that is likely to deteriorate: this is the case of nutrition exploration at the return of lactating cows before calving or urinary acid-base balance of dairy cows.
You will find in our page « early indicators » the description of our parameters.
Come discover our quality process, unique in Europe for this type of analysis and you will find in our part « written for you » various publications validating our process and our analysis.
Our analysis grouped into packages offer you the opportunity to explore at once all the relevant parameters. You will find a description of these packages in both our analysis request form and our catalogue of benefits (Analysis rates and Fodder rates).
Acid-base balance
Everyone knows of one or several farms that « do not work », where cows do not produce milk as they should, where cows are apathetic, etc… and where a classic » alimentation approach « (UFL, PDI, calcium, phosphorus, chronic acidosis) does not identify any explanation. Obviously in these farms, the answer lies elsewhere ...
Our numerous interventions on farms have enabled us to identify emerging issues to understand problems so far unresolved. These issues are based on evaluating mineral and acid-base balance
.
Indeed, anomalies of supply (deficiency or excess) of strong ions ( Na, K, Cl ), may lead to disturbances of the acid-base balance and cause important clinical signs in the herd, such as sub-ingestion, under-production, massive incidence of downer cows, udder oedema during lactation, etc.…
Correcting these imbalances may lead to spectacular results within the herd (an increase of 3 to 5 litres of milk per cow, more tonic cows,…).
At the moment, the only way to objectify these disorders is by the analysis of urinary macro-elements.
We have developed innovative and unique in France analysis to enable veterinary practitioners to find answers to the problems of farmers. Aurine collection of 5 cows from the herd as well as an instantaneous measurement of urinary pH are sufficient to make a prodigious jump in understanding the problems.
Do not hesitate to contact us, one of our specialists will be available to guide you through your first steps!
And to illustrate their use we offer a clinical case of dairy cows.
Clinical case
Livestock: 70 DC in strawed area Straw ration + ration of corn silage
Troubles: downer cows at calving time, low persistence, under production and reverse rates
First tracks: acidosis in the herd, transition dry - lactation unsatisfactory.
The study of diet and food conduct did not show risk factors for acidosis.
It was decided to do urinary analysis

The acid-base balance shows a state of metabolic alkalosis, the correlation between pH and bicarbonates is of 0.61, which is acceptable. The excretion of bicarbonates is high, it may come from direct contributions. The other source of these excretions corresponds to an insufficient supply of chlorine, because the sum of bicarbonates + chlorine is necessarily a constant. In livestock, the levels of chlorine and potassium are marginal, so it is possible to add these elements in the diet.
RECOMMENDATIONS
Reduce the intake of bicarbonate to 80g per day.
Provide 100g per day of OD Ionik for a month and make a urinary control in 15 days
One month later

The urinary acid-base balance has normalized.
Continue inputs
IN THE LIVESTOCK Production has increased by 3L per cow with a more pronounced effect on multiparous (see production curves OPLAIT ) rates are standardized (see output curves of OPLAIT) says the farmer, cows drink more and have a shinier hair.
EPILOGUE
The farmer won 3L of milk per cow which leaves a comfortable margin even after purchasing the product and the payment of analysis.
These were crucial in this success. A classic approach of livestock would have led to an acidosis situation, confirmed, it's true, by the analysis of fat and protein rates. It would have been logical to distribute sodium bicarbonate in order to fight against this state.
This supply would have caused a significant decrease in production since we were in alkalosis (see urinary pH and urinary TCO2u = urinary bicarbonates of the first analysis) chlorosensible (see urinary Chlorine of the same analysis ).
A supply of bicarbonates would have exacerbated the state of alkalosis and at the same time, hypokalemia. The insufficient supply of chlorine would have maintained hypovolemia and under production.
However, it is the supplements of Potassium, Magnesium and Chlorine, which have dramatically improved the results of this livestock.
The livestock has been under, OD-IoniK since.
