Product Description

Prevention of milk fever and hypocalcaemia in newly calved cows

Abnormal low calcium level in the blood around calving is one of the major precursor for a range of production and health problems of dairy cows. All cows will experience a lower calcium level around calving and just a small deviation from the normal level can have a large impact on the cow production performance. Resent research has confirmed that decreased blood calcium level, even within the normal range (>2.2 mmol/L), is associated with increased risk of displaced abomasum, lower milk yield in the first part of lactation and a reduced reproductive performance due to an increased number of empty days.

X-Zelit, the new strategy for improving the transition feeding, has become very popular. The strategy is based on the idea of low calcium supply to dry cows. With less calcium available from the feed, the cow will adjust her hormones to the low-calcium environment condition and begin mobilising calcium from her own bones. In other words the cow’s natural defence mechanism for preventing hypocalcaemia is activated, making her able to use calcium from her own bones and in that way maintain the calcium at a natural level around calving. However, due to the natural content of calcium in common feed ingredients, this is almost impossible to practice under normal feeding conditions. The invention, making it possible to reduce the uptake of ration calcium by adding a calcium binder to the feed, has revived the low feed calcium principle.

The principle is simple; the calcium binder effectively binds feed calcium in the intestine making the calcium less available for absorption. At the time when the supply of the calcium binder is ceased at calving, the hormonal system is then primed and capable of absorbing sufficient calcium into the blood and thereby to the udder.

Importance of a good start of lactation

One of the most important factors for providing a good start of lactation is the calcium level around calving. The calcium level has shown to be one of the most important predictor of other diseases.

Calcium level is important for the muscle function and the immune system. Thus, all levels differing from the optimum will impair the productivity and health status of the animal.

Supplementing X-Zelit in the dry period stimulates the cows own hormone system making her able to maintain the calcium level around calving.

Inadequate calcium level is a widespread issue

More than 50 % of dairy cows suffer from low calcium level at calving

CHART

Low calcium level can be divided into two major categories:

1. Clinical hypocalcaemia or clinical milk fever

Cows need treatment to get back on their feet again, the gastrointestinal function basically stops. Around 4-8 % of dairy cows suffer from this disease

2. Subclinical hypocalcaemia or “invisible” milk fever

The calcium level is below the normal level but the cow will still be standing. More than 50 % of all dairy cows are expected to suffer from low level of calcium around calving. Since this group of animals seldom is treated, it might have greater impact on the economy than the clinical cases of hypocalcaemia.

Importance of a good start of lactation

Calcium plays a major role in muscle function and in cows’ immune system. Preventing the decrease in blood calcium level will consequently decrease the frequency of diseases and increase production efficiency.

Efficiency of X-Zelit

Clinical hypocalcaemia
Using the calcium binder in the two last weeks before calving on 22 farms, which were recognized by veterinarians to have high incidence of clinical milk fever, resulted in 86 percent decrease in milk fever frequency.

On herds, having a low number of subclinical hypocalcaemia X-Zelit has given the following results:
– Increased milk yield (P<0.05)
– Reduced SCC (P<0.1)
– Decreased incidence of metritis (P<0.05)
– Lower risk of culling for multiparous cows (P<0.05)

Directions for use
– 500 g X-Zelit per cow daily the last 2 weeks before calving
– Increased appetite if X-Zelit is mixed into the feed
– Stop applying after calving
