Analyse comparative des stratégies nutritionnelles utilisées dans les fermes laitières robotisées au Canada

Une étude récente menée auprès d’exploitations agricoles canadiennes dotées de robots de traite a révélé une grande variabilité dans les stratégies nutritionnelles utilisées. Quelle que soit la stratégie adoptée par ces fermes, une fréquence moyenne plus élevée des visites au robot de traite était associée à une production laitière plus importante.

L’adoption des systèmes de traite robotisé dans l’industrie laitière canadienne continue sur sa lancée. Avec ce type de système, nous constatons également un changement dans la gestion nutritionnelle, la ration étant divisée entre une ration partiellement mélangée (RPM) et un supplément nutritionnel (souvent sous forme cubée) distribué par le robot.

Benchmarking the nutritional strategies used on Canadian automated milking farms

A recent study of Canadian farms using automated milking demonstrated high variability in the nutritional strategies utilized on those farms. Regardless of strategy, the higher average robot milking visit frequency on those farms was associated with greater milk production.

There has been much variation in the dairy industry in how nutritional management occurs on automated milking system farms. In a recent large benchmarking study of automated milking system farms from across Canada, we aimed to quantify that variation, describing the diets fed on those farms and also detecting associations of nutritional practices with productive metrics from those farms.

Managing high-straw dry cow diets

Maintaining dry matter intake pre-calving by feeding a high-straw diet with proper straw chop length, as well as adding water and molasses, will help keep transition cows healthy through post-calving.

The transition period from the dry period to lactation is a vulnerable time for the dairy cow because she experiences several physiological, metabolic, and behavioural challenges.

Particle size matters for high-straw dry cow diets

In the weeks leading up to calving and the early postpartum period, various behavioral, metabolic and physiological challenges are imposed on the dairy cow.

Managing robot herds to optimize health and welfare

Trevor DeVries and Meagan King

Milking with single-box automated (robotic) milking systems (AMS) has revolutionized the way we can manage and milk dairy cows. Adoption of this technology continues at an exponential rate here in North America.

Give cows the time they need to eat and ruminate

Optimizing the health and production of dairy cows is largely achieved by ensuring cows maintain sufficient nutrient intakes to meet their requirements.

Proper management of dairy cows during the transition period is critically important for both the productivity and profitability of any dairy herd. Nutrition, housing and management during this period all have a direct influence on the health, production and reproduction of cows in the subsequent lactations.

Optimizing the health and production of dairy cows is largely achieved by ensuring that cows maintain sufficient nutrient intakes to meet their requirements. For that reason, high-quality diets need to be formulated to meet those requirements.

Importance of feed access in robotic dairies

We all know feed consumption by dairy cows is critical for maintaining a high level of production. Given that, it is not surprising dairy producers put a lot of time and energy into making sure they have high-quality feedstuffs put together into rations for their cows.

Knowledge of calf behaviour improves performance, weaning

February 27, 2015

Trevor DeVries

If we look at the dairy industry, there are numerous approaches to calf rearing. While there is no one single, current-day approach that is best, there is one optimal way to rear calves we can learn much from. That optimal way of rearing calves is to leave the calf with her dam. This is the way the calf was designed to be raised and nurtured.
