Key Biotin Metabolic Functions
What is Biotin?
Biotin is a B-group vitamin and is an essential nutrient for all animals.
What does it do?
Biotin is critical for a diverse array of metabolic pathways. Of special importance are:
Keratin and lipid synthesis - important for horn production, horn quality and strength
Glucose synthesis - the main energy source for milk production
Natural sources of Biotin
Biotin is present in many foods and feedstuffs in minute amounts (parts per billion).
Biotin is synthesised by rumen microbes. Historically it was assumed that this supply was sufficient for high yielding dairy cows. Trials show that dairy cows respond to supplementary Biotin which suggests that endogenous Biotin supply is sub-optimal.
Why supplement dairy cattle with ROVIMIX® Biotin?
There is an apparent reduction in rumen Biotin synthesis when high-energy diets are fed.
Biotin status of high yielding cows may be reduced when demand is highest.
Trials show increased milk production and improved hoof health when cows are supplemented with ROVIMIX® Biotin.
Benefits of ROVIMIX® Biotin Supplementation
In the past 10 years more than 15 published scientific studies show that Biotin can benefit hoof health and improve milk production. The return on investment is considerable, even in well managed herds.
Consequently, many leading dairy nutritionists, advisors and vets are now recommending Biotin supplementation for dairy cows.
ROVIMIX® Biotin Supplementation Guidelines for Dairy Cattle
1g ROVIMIX® Biotin contains 20 mg biotin.
ROVIMIX® Biotin is a specialist product designed for use by feed manufacturers. Simply ask your feed supplier to add ROVIMIX® Biotin to you dairy concentrates or minerals.
Improving hoof strength reduces the likelihood of problems associated with lameness. Cows with sound hooves eat more, produce more, and are more willing to breed. Treatment costs are also reduced. The overall result is that cows are more profitable.
By improving hoof health, and optimizing horn quality and strength, ROVIMIX® Biotin helps reduce the number of losses due to lameness.
Its outstanding bioavailability means ROVIMIX® Biotin visibly increases strong hoof horn formation. This helps reduce incidences of common problems including white line disease, sole ulcers and digital dermatitis.
Fewer of these problems means lower vet bills and reduced antibiotic use.
Lameness in dairy cows
Lameness is one of the most costly production diseases in dairy farming today. On average, a single case of digital lameness costs around £200. Lameness is a multifactorial disease. Many factors, which often interact, are known to contribute to the onset of clinical symptoms.
Good nutritional management together with improving the environment and management of cows can help reduce the incidence of many common types of lameness. Recent studies show that ROVIMIX® Biotin can help reduce the risk of dairy cow lameness, which contributes to better profitability and animal welfare.
How does ROVIMIX® Biotin work?
ROVIMIX® Biotin improves horn quality. This helps reduce the risk of lameness.
Biotin is essential for keratin synthesis, the major structural component of horn.
Biotin promotes optimal composition and distribution of intercellular cement, which is required for good horn quality and strength.
Field trial results
Over the past seven years, a total of at least 10 controlled research trials have been published on the effects of ROVIMIX® Biotin on the incidence of hoof disorders in dairy and beef cattle. These studies show that supplementing dairy cows with 1 g/d ROVIMIX® Biotin (20 mg Biotin) results in reduced incidence of several of the most common hoof disorders including sole ulcer, white line disease, sandcracks and digital dermatitis.
In a university study with over 2700 Holstein Freisian cows, biotin supplemented herds had:
better locomotion scores
more than 75% reduction of clinical lameness
fewer antibiotic and other treatments
reduced milk somatic cell count (SCC)
To gain the best results, supplementation of ROVIMIX® Biotin should be continuous, all year round. ROVIMIX® Biotin is also important for dry and transition cows to help minimise the disruption of horn growth that occurs around calving.
Biotin is essential for milk production as it increases the production of glucose by the cow. More glucose means higher milk yields. Supplementing high-yielding cows with ROVIMIX® Biotin has resulted in milk yield increases of almost 2kg per cow per day.
Increase milk production
New studies show ROVIMIX® Biotin increases milk production in high yielding cows
The following shows a summary of milk production - response to 1g/day ROVIMIX® Biotin (20 mg Biotin)
How does it work?
ROVIMIX® Biotin improves the efficiency of energy metabolism through its involvement in numerous enzyme systems and metabolic pathways. Ultimately, ROVIMIX® Biotin increases the amount of glucose synthesised in the liver. Glucose is the most important source of energy for milk production.
