This video from the My Forage System channel explains how to analyze cow manure to assess their health and the quality of their diet.
Visual observation is the first step in analysis. The consistency, color, and content of the manure should be examined.
Consistency: The ideal consistency is between a score of 1 (liquid manure) and 4 (firm manure). Manure that is too liquid indicates a digestive problem, while manure that is too firm can be caused by a lack of water or fiber.
Color: The color of manure varies from light brown to dark brown, depending on the type of food consumed. Black manure may indicate a health problem, while green manure may indicate the presence of pests.
Contents: The content of manure may include grains, fibers, and undigested food particles. The presence of pieces of plastic or metal is a sign that the cow is consuming unwanted objects.
Chemical analysis can be used to confirm visual observations and to measure the amount of starch, protein, and minerals in manure.
The interpretation of the results of the manure analysis makes it possible to:
Assessing cow health
Identifying digestion problems
Detect nutrient deficiencies or excesses
Adjusting the cow's diet
Additional tips:
It is important to observe the manure of several cows to get a good idea of the health of the herd.
It is important to take samples of fresh manure as the composition of the manure may change over time.
It is important to work with a veterinarian or animal nutritionist to interpret manure analysis results.
