Live Yeast & Buffers in Beef Animals

Whether beef prices are on the up or on the way down, it is always possible to improve returns by increasing efficiency. The use of Biosprint live yeast in beef diets can help to do just that; the benefits include reduced cost per kilo live weight gain, a reduction in the overall feed bill and a faster turnaround of animals. The Wynnstay Prime Beef range incorporates Biosprint to maximise the benefits of this premium range. Biosprint is a unique strain of yeast that has been shown to increase live weight gain and
feed convers ion efficiency in both semi-intensive and intensive feeding systems. Data submitted to the EC for approval of Biosprint as a feed additive shows the boost in growth rate for Beef Cattle ranges from 7 to 10.6%, with 9% improvement being typical on semi-intensive diets. Where starch content of the biosprint logodiet is increased, as seen in intensive beef systems, the enhancement tends to be at the higher end of that range.

Where starch content of the diet is increased, as seen in intensive beef systems, the enhancement tends to be at the higher end of that range.

Biosprint works by helping the rumen microbes cope with the challenges of modern ruminant diets, acidic silages or high levels of starch. The yeast stimulates efficient bacterialbeef cattle smethcote action and helps reduce the challenges of acidosis by modulating rumen pH. Live yeast also acts as an oxygen scavenger helping keep the rumen anaerobic, again improving rumen efficiency. So what does this mean to the cost of producing beef in 2015? Using today’s prices for feeding stuffs on a semi-intensive system (beef nuts and grass silage), where livestock at 400-500 kg live weight are expected to grow at say, 1.2kg per day, diet cost averages 130p per kilo live weight gain (LWG). Using Prime Beef nuts and increasing live weight gain to 1.3kg, the cost per kilo LWG reduces to 120p, so the longer Prime Beef with Biosprint is in the diet, the greater the benefit. When fed to intensively finished cattle on Prime Beef Premium, the improvement in efficiency can reduce dietary cost per kilo LWG from, 134p to 123p, with livestock reaching target weight quicker and on Biosprint graphaverage, saving 240kg per head of finishing nuts.

However, it does not end there, in a trial of 64 finishing Limousin steers (32 treatment, 32 control) the Biosprint fed group improved LWG by 9% and improved carcass conformation and killing out percentage – better grading is another way to improve margin!

With EBLEX currently reporting the average live weight price of all Prime Beef cattle at 188p per kilo*, this saving represents an increase in margin of over feed cost of 18.5%. Naturally all livestock and feeding stuffs vary and individual costing depend upon individual circumstances.
