Why add extra vitamins to mink feed?
In the past, adding extra vitamins to feed was considered unnecessary, as the feed compound already contained added and natural vitamins. It has now been proven that moisture content and ingredient quality fluctuate, and therefore a mink farmer can never be sure that the mink’s need for vitamins is fully met in critical periods. Adding extra vitamins to the feed ensures that the mink has the ideal prerequisites for breeding and fur development.
– Liquid vitamin B. Vitamin supplement containing all the important B vitamins.
As many mink are fed raw fish such as herring and sprat, these same mink quickly become deficient in thiamine (vitamin B1), as these fish species contain the enzyme thiaminase, which breaks down thiamine.
Thiamine deficiency is apparent when the mink’s general health begins to deteriorate. Gestating minks miscarry, whereas other minks lose their appetite, resulting in weight loss and infirmity. Ultimately the mink dies. If there is a risk of thiamine deficiency, Success B-Complex can be added to the diet.
Certain B vitamins have a very positive impact on the liver’s fatty-acid metabolism, and without these vitamins, a nutritional imbalance could arise, which in some instances causes death due to an enlarged fatty liver. This is typically seen in fat male kits and fat breeding animals. Adding Success B-Complex to the diet can remedy this nutritional imbalance caused by vitamin-B deficiency.
As a supplement for ordinary feed.
Mink at risk of thiamine deficiency, fatty liver, nursing disease or fur disorders and when developing fur.
In confirmed instances of thiamine deficiency or nursing disease, it is advisable to supplement Success B-Complex with our injectable vitamin Becoplex Vet, as directly injecting the vitamin accelerates uptake.
As a supplement or for winter-fur development: 1–2 ml/kg of feed
- Natural vitamin E with liquid selenium
Vitamin E with selenium has a positive effect on the mink’s internal production of antioxidants. This helps to support the mink’s immune response system and enhances its resistance to disease.
Vitamin E can also be administered before mating as it helps to increase fertility at reproduction.
Success E-100000/d-alpha/Selenium is made especially for mink, as the composition of natural vitamin E and selenium protects mink’s cells against oxidants. Oxidants are prevalent in feed containing large amounts of unsaturated fatty acids, e.g. fish fat or rancid fat, for instance. Without this cellular protection, mink can become malnourished and develop “yellow fat disease”, seen in rapidly growing mink kits, etc.
Breeding animals before mating, nursing females and mink kits after weaning.
Is given during critical periods of stress, heightened disease frequency and higher incidence of sudden deaths.
For vitamin E deficiency or during critical periods: 1–1.5 ml/kg of feed
Natural or synthetic vitamins?
As synthetic vitamins have to be decomposed in the mink’s intestines before they can be absorbed, this reduces the absorption window and, as a result, the mink does not get the maximum benefit of synthetic vitamins.
The results of an experiment conducted by Søren Krogh Jensen (Aarhus University, 2004) conclude that during the first four weeks of nursing, mink bitches and mink kits absorb natural vitamin E 2.5 to 3 times better than synthetic vitamin E.
