Modern day high producing dairy cows are under continuous pressure to produce milk and sometime in the most difficult of conditions. Balancing the ration to maximize the rumen turnover can sometimes meet up to two third of the energy and protein requirement for milk production. Feeding by-pass protein has traditionally been the channel used to meet the extra protein requirements of the cows. Except when feeds like fish meal, which is not allowed in most countries in ruminants rations, is fed, the most limiting amino acid (METHIONINE) in the rations of ruminants is not balanced.
Performances of dairy cows and beef cattle are therefore not always optimal.
The best approach to feeding modern dairy cows and beef cattle should integrate precision balancing of the ration for limiting amino acids, most importantly methionine and to some extent lysine. When protein blends or straights (rapeseed, soya meal etc.) are the main protein source of the ration of high performing dairy and beef herd, balancing for METHIONINE, the most limiting amino acid, is required to optimize performance.
Aside from the important benefit of improving performance (yields, milk quality, fertility, and health) there is also the cost saving benefit of balancing for limiting amino acids. With soya price so high, precision balancing for limiting amino acids can save on the cost of feeding by replacing some expensive protein sources in the ration. Depending on the feeding objective, the feeding of MEPRON can either be cost neutral or cost saving for the farmer.
Whatever the balancing objective adopted, there is consensus in the literatures/ on farms on the milk yield effect when fed as top up or to replace some expensive protein concentrate or blend. Additional benefit in milk protein, reduction in post calving problems and improved health have been reported in literatures and on farms.
There is also the added contribution of methionine balancing to the reduction of another important greenhouse gas (nitrous oxide) from dairy and beef herds.
In addition to improved absorption in the mammary gland, methionine supplementation increased gastrointestinal tract absorption and consequently improves nitrogen efficiency.
Feeding rumen protected methionine (MEPRON) has been demonstrated to reduce urine/ faecal nitrogen excretion and has the potential to improve efficiency of protein utilization for milk production by 20%.
Balancing for methionine allows for a reduction of anything between 1 and 2.5% protein in the ration. The consequence of which is a reduction in urea and nitrogen excretion in the faeces and urine. This will reduce the nitrogen content of the slurry/ muck and consequently reduce nitrous oxide emission into the environment.
Nitrous oxide has global warming potential that is 298 times as powerful as carbon dioxide (methane has global warming potential of 28 times as powerful as carbon dioxide).
We recommend the feeding of MEPRON during transition. This is because methionine, being a methyl donor, can help to reduce ketosis.
Feeding rumen protected methionine (MEPRON) during transition has also been demonstrated to help to improve intake post calving. Since most of the health issues, post calving, is related to negative energy balance, increasing the intake of the cow will return fresh cows/ heifer into neutral and then positive energy balance quicker.
It has also been reported that feeding rumen protected methionine like MEPRON during transition and continuing into lactation can help to improve fertility (please refer to the link below to get more information on how feeding methionine during transition improved performance).
Growing and finishing cattle rations can also benefit from methionine balancing. Aside from savings in feed cost, better weight gain has been achieved on many farms that we have replaced some or all traditional protein sources with MEPRON.
There are numerous methionine and lysine sources in the market. However, not all of them are suitable for ruminant animals. Only those that are rumen protected (not analogues) and, most importantly, true methionine sources (like MEPRON) give the best and most consistent results. It is for this reason that Ruminant Management Limited has endorsed and is promoting the rumen protected methionine source (MEPRON).

Conserved forages are the most important feed on most farms because of their influence on the extent of farm’s profitability. Coincidentally, they are also the only feed on the farm that the farmer has a significant level of control over.
It is almost impossible to make good quality silage without some form of intervention. The consequences of bad weather at harvest are for example unavoidable. However, measures should be taken to prevent avoidable consequences like mycotoxins, loss of nutrients, fermentation by bad bugs, aerobic instability etc.
An investment in silage additive is therefore considered to be the smartest, smallest, and arguably, the most important investment a farmer will be making every year. That's right, "it has been proven beyond reasonable doubt, that farmers are throwing money away by not using silage additive." I know you've read or heard it a million times but it's true.
But are farmers using the right silage additive? It is undeniably a trying proposition when farmers must choose from dozens of different products that all claim to do the same thing. The fundamental reason to invest in silage inoculants is to:
Unfortunately, not all silage additives available in the market are equipped to perform these fundamental roles.
That is why we researched the market and endorsed ADDCON’s KOFASIL range of silage additives. All Kofasil range of silage additives have been tried and tested under the UK condition and they all carry the German Agricultural Society (DLG) SEAL OF APPROVAL.
All Kofasil range of silage additives and preservatives can also be sourced through Ruminant Management Limited.
