INACTIVE DRIED YEAST (Saccharomyces cerevisiae)

INACTIVE DRIED YEAST(Saccharomyces cerevisiae)

DEFINITION

• Inactive Dried Yeast, Brewers Yeast and Molasses
  Yeast are all the same ingredient, as all of them
  are made of 100 of Saccharomyces cerevisiae
  Yeast.
• Brewers Yeast comes typically from a beer
  fermentation. The Inactive Dried Yeast coming
  from alcohol fermentation, either from sugar cane
  molasses (Brazil) or from corn syrup (USA) can
  also be called as Brewers Yeast. In Brazil, the
  brewers yeast coming from sugar cane molasses
  fermentation is usually called as MOLASSES YEAST.
• ICC chose the definition of INACTIVE DRIED YEAST
  for our brewers yeast coming from molasses
  fermentation.

INACTIVE DRIED YEAST

• Inactive Yeast is known for its prophylactic
  action, increasing the animals resistance to
  illness and improving performance, this activity
  is often referred as Unidentified Growth
  Factors UGF.
• Due to its high palatability, Inactive Dried
  Yeast stimulates the feed intake.
• Inactive Yeast is a great protein source, with
  good amino acids balance and high levels of
  lysine and threonine and it is also the best
  source for natural occurring B vitamins.

ADVANTAGES OF YEAST USAGE

• Sows - feeding the sows with Inactive Dried Yeast
  increases the number of piglets born alive,
  piglets weight at birth and at weaning.
• Piglets - strengthen the immuno system and
  increase the production factor.

INDICATION OF USE

• Swines
• Pre initial and Initial 2 to 5 of total feed
• Growth and Finishing 1 to 3 of total feed
• Sows 1 to 3 of total feed

• When gestating and lactating sows are fed with
  21 of Inactive Dried Yeast (IDY) the
  improvements on litter weight at birth, at 21
  days and at 35 days were very important.
• Best litter weights were reached with 14 and 21
  inclusion rate of IDY.
• These results showed that the IDY can be used up
  to 21 of the diet, as a prophylactic micro
  ingredient for gestating and lactating sows.

• Inactive Dried Yeast (IDY) addition enhanced
  Bifitobacterias and Lactobalilli count in the
  feces, while decreased Clostridium Perfringe
  count.
• 3 of IDY in weaning piglets diet, was able to
  provide higher serum immunoglobulin G (IgG)
  levels.

• Inclusion of Inactive Dried Yeast (IDY) enhanced
  piglets performance.
• 5 of IDY provided better feed conversion in
  piglets (from 22 to 71 days old).

• 15 of Inactive Dried Yeast inclusion provided
  better feed conversion and serum hemoglobin level
  results.

• 20 of Inactive Dried Yeast level, decreased
  serum cholesterol and urea concentration in the
  weaned pigs.

CONCLUSION

• Inactive Dried Yeast, either from molasses
  fermentation or from brewers fermentation, can
  be considered an efficient ingredient for swine,
  especially for weaning piglets and for sows, both
  for its nutritional characteristics and for its
  prophylactic action. In general, Inactive Dried
  Yeast enhances the immunological system.
• Several trials showed that Inactive Dried Yeast
  decreases piglets mortality and increases weaned
  piglets livability.
