  1. INACTIVE DRIED YEAST (Saccharomyces cerevisiae) www.yeastbrazil.com

  2. INACTIVE DRIED YEAST • Inactive Yeast is known for its prophylactic action, increasing the animal’s 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. www.yeastbrazil.com

  3. ADVANTAGES OF YEAST USAGE • Layers - Inactive Dried Yeast increases the production factor, improves egg shell quality and fertility. • Broilers - Inactive Dried Yeast should be used mainly on initial phase (1 to 21 days old, or 1 to 10 days old), it decreases deleterious effects caused by stress factors such as high temperature, over population, mycotoxins contamination, etc. www.yeastbrazil.com

  4. INDICATION OF USE POULTRY • Initial Phases 1.0% to 2.5% of total feed • Other phases 0.5% to 2.5% of total feed www.yeastbrazil.com

  6. THE USAGE OF INACTIVE DRIED YEAST IN THE BROILER FEED.BUTOLO, J.E., BUTOLO, E.A.F., NOBRE, P.T., SERAFINI, F.V. • EXPERIMENTAL DATAS: • Local: Supremais Research Center • Animals: 300 chickens (one day old) • Periods: 1-21, 21-35, 35-42 and 1-42 days. • Treatments: 0%, 2.5%, 5.0% and 7.5% of yeast inclusion. • Experimental Period: 71 days www.yeastbrazil.com

  7. Broilers Weight Gain (g) www.yeastbrazil.com

  8. Broilers Feed Conversion www.yeastbrazil.com

  9. CONCLUSION • The best performance were reached with inclusion rate of 2.5% of Inactive Dried Yeast. • The broilers fed with 2.5% of Inactive Dried Yeast showed better (P>0.05) results of weight gain, feed intake and feed conversion in the total period than the others treatments. • The evidences suggest low levels of Inactive Dried Yeast inclusion rate provided positive results to broilers performance. www.yeastbrazil.com

  10. STUDIES ABOUT HEN FEEDING WITH GROWING LEVELS OF INACTIVE DRIED YEAST (Saccharomyces cerevisiae).BOTELHO, F.G. A., BUTOLO, E.A.F., NOBRE, P.T.C., BUTOLO, J.E., LIMA, I.A.V., SERAFINI, F.V. EXPERIMENTAL DATAS: • Local: Supremais Research Center • Animals: 360 ISA Brown hens (18 weeks old) • Treatments: 0%; 2.5%; 5.0% and 7.5% of yeast inclusion • Experimental Period: 16 weeks (4cycles) www.yeastbrazil.com

  11. Table1. Average of hens productives parameters feeded with molasses yeast www.yeastbrazil.com

  12. DWG=daily weight gain; DFI=daily feed intake; FC(12 eggs)=feed conversion to twelve eggs; FC (egg mass)=feed conversion to mass of egg. Cycle1 – 20 to 23 weeks; Cycle2 – 24 to 27 weeks; Cycle3 – 28 to 31 weeks; Cycle4 – 32 to 35 weeks; Total – 20 to 35 weeks www.yeastbrazil.com

  13. RESULTS 1 • Weight gain - the linear growth of Inactive Dried Yeast in feeds, provided increases on weight gain (P<0.04) in the 1st cycle. In general, best results were obtained with 2.5% of Inactive Dried Yeast inclusion rate. • Eggs production (laying) - there was significant increase (P<0.04) of eggs production only in the 2nd cycle. Best result was achieved when using 5.0% of Inactive Dried Yeast. • Eggs weight - 2.5% of Yeast addition improved the eggs weight in the 2nd, 3th and 4th cycles (P<0.03). www.yeastbrazil.com

  14. RESULTS 2 • Feed conversion - the lowest levels of Yeast inclusion provided a better response in on feed conversion rates. • Yolk egg color - there was linear positive effect (P<0.02) on the egg yolk color only on the 2nd cycle, with inclusion of 2.5% of Inactive Dried Yeast. www.yeastbrazil.com

  15. CONCLUSION • It is feasible to add Inactive Dried Yeast up to 7.5% in the hens feed, during the period of 19 to 35 weeks of age. • Evaluating the two first cycles (27 weeks age), best results of laying, daily weight gain, feed intake and feed conversion, were found when used 5.0% of Inactive Dried Yeast. • In the 3th and 4th cycles (28 weeks-), low inactive dried yeast inclusion levels (2.5% and 5.0%) provided the best responses on egg weight and feed conversion. www.yeastbrazil.com
