ENERGY BOOST FOR HIGH YIELDERS IMPROVES FEED


EFFICIENCY Cargill Animal Nutrition has introduced the energy boosting feed product Turbopro® to its range this autumn (2019). A blend of rumen protected B-vitamins and palatability enhancers, it has been shown to improve milk production by 1.8kg per day in early lactation and by 1.2kg per day in mid lactation. Turbopro is added to minerals or in


feed and recommended for high yielding cows producing more than 29 litres of milk per day in early or mid lactation. Its main function is to support glucose production in the liver.


“Propionate is a fatty acid produced in


the rumen that, in the liver, is synthesised into glucose,” says Cargill ruminant technical manager Philip Ingram. “We know that 85% of gluconeogenesis occurs in the liver, and that glucose is the main energy source used in milk production. So, if the efficiency of this process is improved there will be more energy made available for milk production.” A key component of Turbopro is the


rumen-protected B-vitamins. This additional supply of B-vitamins is available in the intestine of the cow for key functions such as milk production, health, fertility and maintenance. “Unprotected B vitamins can be


digested in the rumen, for example only about 2% of standard vitamin B12 passes through the rumen, as opposed to 60% of the supplemented rumen-protected vitamin B,” adds Dr Ingram. “High yielding cows can benefit from additional amounts of this vitamin.”


Cargill trials on more than 1,000 dairy


cows have shown improvements in milk production where Turboprop has been added to diets of milking cows from early lactation. Results have also shown that an improvement of 1.2kg per day of milk in mid


lactation did not significantly affect fat or protein production. Turbopro can be fed to all lactating


cows and it is an ideal follow on to Cargill’s LiFT™ that is fed to cows three weeks pre calving to prime the liver for better energy management and help to reduce ketone production – that affects intakes – and improve how the liver processes fat from body reserves. “Nutritionists and dairy producers are


encouraged to look beyond the rumen when it comes to improving feed efficiency in our milking herd,” says Dr Ingram. “Improving how efficiently the diet is used by the cow, rather than adding more high value feed inputs, will increase feed conversion in the cow.”


Turbopro has been shown to provide


a return on investment of 5:1 based on a milk price of 25ppl, or 6:1 based on a milk price of 30ppl.


NEW WEAPON IN BATTLE


AGAINST MYCOTOXINS Combining independently proven activated clay minerals with glycerine to provide enhanced mycotoxin control and improved liver function, Mycotrap from UFAC-UK is a new mycotoxin adsorbant, effective against the eleven most commonly occurring mycotoxins in animal feeds. Mycotoxins are toxins produced by


moulds and fungi that colonise feedstuffs. Even at low levels they will reduce performance in cattle, sheep, pigs and poultry. Producers will benefit from including supplements in the diet which bind or adsorb the toxins rendering them inactive and excretable so reducing the risk. From independent tests at Gent


University in Belgium, Mycotrap has been shown to have exceptional binding capacity for a broad range of economically damaging and commonly occurring mycotoxins including Aflatoxins, Fumonisin, DON and


ZEN. It is proven to be effective at all the pH ranges found throughout the gastrointestinal tract in ruminants and monogastrics. “Mycotrap contains a specialised


mineral complex which effectively adsorbs the majority of mycotoxins known to cause reduced productivity and increased disease risks in all classes of farm animals,” explains Mike Chown of UFAC-UK. “As well as minimising the risk of mycotoxin poisoning, Mycotrap has uniquely been developed to help the animal cope with the consequences with the inclusion of glycerine.” As a precursor of glucose, the addition


of glycerine helps boost the animal’s energy supply to fight infections by supporting recovery of the immune system. In addition, glycerine helps minimise the deterioration of feeds caused by the moulds which produce mycotoxins by inhibiting mould growth in both feeds and finished rations. “Mycotrap gives producers a two-


pronged approach to preventing mycotoxins from reducing livestock performance and productivity. By minimising the initial risks and then helping the animal resist the challenge, Mycotrap is a new weapon in the battle against the most commonly occurring mycotoxins.” The typical feed rate for ruminants is


25 grams/head/day or included at 3-5kg/ tonne in finished feed. It costs around 6p per cow per day.


MOLASSES BLEND BOOSTS


ROBOT VISITS A new super-filtered molasses blend developed by ED&F Man and the Lely Centre Yeovil will increase daily visits to robot milking systems and increase milk production.


“Optimising voluntary visits per day is


vital to drive maximum performance from robotic milking systems,” Dr Phil Holder from ED&F Man explains. “Robo-Mol has been developed to help increase the animals’
