“…In agreement with the present study, different types of yeast in the diets of laying hens had no effect on body weight , feed intake (Vogt et al, 1974;Bornstein et al, 1982;Rojas Ramirez et al, 1985;Ö nol and Yalçın, 1995), egg production (Vogt et al, 1974), egg weight (Vogt et al, 1974;Bornstein et al, 1982;Richter et al, 1985;Shyam Sunder et al, 1990;Ö nol and Yalçın, 1995) and feed efficiency (Vogt et al, 1974;Shyam Sunder et al, 1990). However, Daghir and Abdul-Baki (1977) observed a growth depression when one-third of the soyabean meal and all the fish meal were replaced by 10% molasses-grown yeast and this was attributed to the deficiency or poor availability of methionine in the yeast.…”

This experiment was carried out to determine the effects of the usage of dried brewing yeast in quail diets on laying performance, egg traits and blood parameters. A total of 240 Japanese quails (Coturnix coturnix japonica) aged 10 weeks were randomly allocated into one control group and three treatment groups. Each group was divided into five replicates as subgroups, comprising 12 quails each. Dried brewing yeast (Saccharomyces cerevisiae) was used at the levels of 1.5%, 3.0% and 4.5% in the diets of the first, second and third treatment groups, respectively. Soyabean meal was replaced with dried brewing yeast. The diets were formulated to be isocaloric and isonitrogenous. The experimental period lasted 18 weeks. Dietary treatments did not significantly affect body weight, daily feed intake, daily protein intake, egg production, egg weight, feed efficiency, mortality, egg shell thickness, egg albumen index, egg yolk index, egg Haugh unit, the percentages of egg shell, albumen and yolk, excreta moisture and small intestinal pH. Inclusion of 3% and 4.5% dried brewing yeast in diets reduced egg yolk cholesterol concentration as mg per yolk and mg per g yolk ( P , 0.01). Blood serum cholesterol of groups fed diets with dried brewing yeast was significantly lower ( P , 0.01) than that of the control group. Feeding diets containing 3.0% and 4.5% dried brewing yeast resulted in significant increases ( P , 0.01) in blood serum levels of total protein, alanine aminotransferase at the end of the experiment. Blood serum levels of uric acid, triglyceride, aspartate aminotransferase and alkaline phosphatase were not affected by dietary dried brewing yeast. It is concluded that dried brewing yeast can be used up to 4.5% in the diets of laying quails without adverse effects on the measured parameters.

In a 3-generation experiment with a total of 2520 hens and 210 cocks of the species 'White Leghorn' kept in cages, the compatibility of 5.0%, 7.5% and 15% 'fermosin' torula yeast in the mixed feed ration was tested under long-term toxicologic aspects. The parameters investigated and relevant for the toxicological statement, with high probability, did not show a negative influence of the test ration. Thus, a good compatibility of the tested yeast product 'fermosin' for laying hens can be stated.
