| 23/12/07 Trouw Nutrition has developed a new silage corrector product
                      to help livestock producers counter some of the rumen problems
                      associated with this season’s poor quality forages.
                     The company reports that silages on many farms this winter
                      have a “fruity” character, with chemical analyses
                      showing lower energy levels and high concentrations of
                      acetic acid and/or lactic acid.
 “Units with poorer quality silage are responding
                      as usual by feeding additional concentrates, often in combination
                      with a rumen buffer to counter rumen acidosis problems,” reports
                      Trouw Nutrition technical manager John Twigge.
 
 “However, this winter the buffer response time often
                      seems to be greatly extended. Normally, we’d expect
                      a response within seven days, but on some farms there has
                      been little sign of improvement until 15-20 days post buffer
                      introduction.
 
 “This suggests the problem lies less in the simple
                      neutralisation of excess rumen acid, but more to do with
                      the colonisation of the rumen with a particularly aggressive
                      bacterial population that is producing large amounts of
                      acid. It appears the rumen really is a bacterial battleground
                      this winter.”
 
 “What seems to be happening this year is that the
                      rumen micro-organisms which produce lactate (such as Streptococcus
                      bovis) are gaining the upper hand over the lactate users
                      (such as S.ruminantium and M. elsdennii.) But where this
                      is happening, the introduction of the new Maxcare Silage
                      Corrector product will be a useful tool to help producers
                      right the balance,” John Twigge says.
 
 Maxcare Silage Corrector is fed at 150g/cow/day, this product
                      is a combination of live yeast – to increase lactate
                      utilisation and regulate the rate of substrate fermentation – and
                    rumen buffer to neutralise excess rumen acid.
