Nutri-LINK Transition Dry Cow 400

If calcium metabolism is impaired the symptoms include:

Poor Muscle Contraction

The rumen and uterus are two key muscles. Calcium deficiency at calving reduces the strength of these muscles.

Calving Difficulties

Where the uterus is slow to contract and the calving process takes too long. Often causes weak or dead calves.

Retained Cleansings

Similar to the above, contraction is weak and fails to expel the cleansing post calving.

Sub Clinical & Clinical Milk Fever

A metabolic disorder when the calcium “demand” is not available quickly enough for milk production at or immediately after calving.

Poor Dry Matter Intake Post Calving

The rumen being a key muscle requires calcium to “drive” feed intake post calving. Poor dry matter intake pre-disposes the cow to negative energy balance in early lactation.
Some or all of these symptoms may be present in the herd.

The Cause

The presence of these symptoms is a possible/likely indicator of an imbalance of cations and anions in the diet of the cow (DCAB balance). Put simply, too many cations leads to a higher pH in the blood – this leads to poor solubility of calcium and therefore, poor availability in the body.

These extra cations are produced from excess potash from forage, commonly increasing in grass silage over recent years. Slurry spread in the spring rather than autumn, leads to increased potash levels in the silage when 1st cut is taken.

How to Diagnose a Challenge to Dry Cows

Silage mineral analysis. Take a sample from the dry cow pit. Mole Valley Feed Solutions will analyse for a complete mineral profile. An excess ratio of potash (potassium) and sodium to other elements such as chloride and sulphur is relevant to high CAB values in forage.

The Solution

We must rebalance the cations and anions in the diet. The Transition Dry Cow 400 supplement fed for a relatively short period can have major positive benefits.
Incorporate straw as part of the total diet as it is very low in potassium to help counter the effects of many grass silages which can be high. The use of straw also improves rumen function and reduces metabolic problems during the immediate calving period.

Feeding Rate

Feed Transition Dry Cow 400 at 400g/cow/day in the last 21 days pre calving. Immediately withdraw the supplement post calving and move cows onto a traditional lactating dairy mineral.

Transition Dry Cow 400 must be mixed with the TMR at all times before feeding.

Contains

  • Range of anionic salts
  • Chelated forms of organic copper, manganese, zinc and Selplex as standard
  • Very high levels of vitamin E to help boost immunity and muscle function
  • Multiple sources of copper
  • Fully fortified with minerals, vitamins & trace elements

Important

A mineral specialist should be consulted before feeding a partial DCAB transition ration.

Efficient Calcium metabolism is absolutely vital for successful, problem free calving of dry cows. Calcium has a major role in muscle contraction, nervous function and is a major component of milk.
We are able to modify the dry cow system to suit the needs of progressive UK dairy farmers who are looking to feed a TMR transition diet to dry cows in the last 21 days pre-calving.
