Provita Advance+ silage inoculant is a unique formulation combining EU approved and UFAS approved lactic and acetic acid bacterial strains at a guaranteed rate of 1.2 million cfu per g of forage. Performance benefits include +1 litre of milk per cow per day and up to +30% better growth rates. Better fermentation is also shown with 46% more sugar, 33% less ammonia and double stability time at feed out. (Source: EU reg data and in-house data) Read more

The question is often asked as to whether silage inoculants are needed when the weather is good, or is it just when the weather is poor? Provita Advance+ is like the icing on top of the cake, silage will be even higher in sugars and nutritional quality in good weather conditions. Read more
At this time of year farmers are bombarded with information on silage inoculants. With so much variation between years and cuts, it’s very difficult to compare silage inoculants or even treated verses untreated crops. Many products claim to be better than the next one, so how can they actually be compared?
It is advisable to check the bacterial strains are EU approved. The EU registration system has standard parameters to measure efficacy such as dry matter losses, pH, lactic acid and ammonia plus stability for wholecrop and maize silages. Parameter testing shows efficacy on easy, moderate and difficult to ensile crops. Some of the inoculants, in particular the ones that only apply 100,000 bacteria per g of grass, failed to show a benefit in moderate and difficult to ensile crops.
Ryan McMullan runs 60 Holstein cows in Carnlough, Co Antrim. They are currently yielding 8000L on 46kg silage mixed 50:50 1st and 2nd cut plus 5kg in wagon and rest of meal topped in parlour to yield. A few years ago he decided that he needed to improve silage quality in order to improve herd performance.
The first aim was to cut silage earlier; however with heavy land this can be difficult. The silage ground gets 4000 gallon per acre, this year it was put on with his umbilical slurry system, which has been invaluable. Next only 60 units of N is applied for the first cut in early April, this means silage can be cut from early May, second cut get 2 bags per acre of 27.4.4 plus sulphur and it was cut third week of June, third cut was delayed until September . Again mowing and ensiling is done by Ryan’s machines. It is mowed with a mower-spreader, gets a 24 hour wilt weather permitting, rowed up and then ensiled with a trailed harvester, aiming for a DM of 28% to 32%. Read more
One of the most common questions around silage making time is, how many tonnes per acre are there?
Provita’s Tommy Armstrong suggests the following method.
“Silage yield can be assessed very easily by simply weighing the actual quantity of grass cut from a half metre by half meter quadrat.
“When doing farm trials this year, I wanted to be very accurate in the application of our silage inoculant Advance+.
Its strains have been tested through the EU registration system plus it has been tested on farm in mini-silo and split-silo tests.
“We’ve tested it on farm from 18% to 60% dry matter, from 0.7% to 9% sugars on grass wholecrop and maize. Provided good management is also practiced its use results in better fermentation, stability and predicted animal performance,” commented Tommy Armstrong.
