Cow trial in Australia evaluates effectiveness of Vilofoss' calcium binder
The effectiveness of Vilfoss' X-Zelit calcium binder was compared with the effectiveness of another product during a recent farm trial in Australia.
Both products aim at improving a cow's transition from the dry period to the lactation period by sustaining the level of calcium around calving.
Blood tests showed a high calcium level for both treatments - however, they further showed that X-Zelit treated cows had a higher level of serum calcium than cows treated with the other product.
A higher calcium level during calving has a positive effect on many production characteristics. Among other things, such a level contributes to the cows being more vigorous after calving and having a higher feed intake.
The rumination time was higher from the start of lactation for the X-Zelit group as well as throughout the 82 days during which the cows were observed. This indicates that cows that are off to a good start in lactation, retaining the benefit for a very long period. The result is consistent with the Cornell experiment, where a 30 minutes/day increase in rumination was observed in the first week of lactation.
Increased rumination and higher feed intake result in more milk.
The yield was higher from the start of lactation for the X-Zelit group, which also maintains a higher yield level throughout the first 82 days of lactation.
