Effect of Yeast Culture on Growth Performance, Haematological and Biochemical Indices of New Zealand White Rabbits

Abstract

Effect of Sacchoromyces cerevisiae live yeast culture on growth performance, haematological and biochemical indices of rabbits was studied with 6-7 weeks old New Zealand white rabbits. Thirty male rabbits were divided equally into 3 groups; I.control group (basal diet), II.group (added S. cerevisiae, 2 g/kg diet) and III.group (added S. cerevisiae, 4 g/kg diet). Blood samples were obtained via ear venipuncture on the 85th day of feeding yeast of rabbits. No significant difference was observed in blood composition and growth performance by S. cerevisiae. Leukocyte, haematocrit and haemoglobin concentration slightly increased while serum cholesterol slightly decreased by S. cerevisiae (p>0.05). However, monocyte count (p<0.05) increased in groups fed 2 g/kg and 4g/kg S. cerevisiae. Yeast culture has a positive effect on immune system. Increased monocyte value by S. cerevisiae is beneficial in improving the immunity. On the other hand, other parameters of natural and induced immune system may be expressed to determine. So, more studies would be necessary to elucidate the effects of supplementing yeast on immunity and determine the optimum dietary concentration in animals.

Normal values of biochemical parameters in serum of New Zealand White Rabbits

“…Total protein level results were similar to our results (11,15,16), and higher than another study (14), while the parameters were reported parallel with our results.…”

“…The previous studies were reported differences in glucose levels that serum glucose levels in live animals can be affected because of different factors such as blood collection procedure environmental conditions and stress. In this parallel, the glucose level results of our study were similar to those of the previous studies (11,15,16), while the glucose result was lower than another study (17).…”

“…role in accurate diagnosis of renal diseases, therefore, some biochemical markers such as creatinine, urea, uric acid and electrolytes levels in serum give knowledge for kidney function (9). In our study, rabbit serum creatinine and BUN levels were determined higher than previous studies (7,11,14,16). There was a statistically significant difference in the serum biochemical parameters between male and female animals.…”

Saccharomyces cerevisiaeas a probiotic feed additive to non and pseudo‐ruminant feeding: a review

“…An increase in the concentrations of haematocrit and haemoglobin, whereas a reduction in cholesterol was observed in rabbits fed S. cerevisiae supplemented diet with 2 g kg −1 feed (Seyidoglu et al ) (Fig. ).…”

Probiyotik Mayanın Yüksek Kolesterol İçeren Diyetle Beslenen Sıçanlarda Kolesterolü Düşürücü Ajan Olarak Kullanılabilirliğinin Araştırılması

“…Further, decrease in cholesterol content of eggs of laying hens and broilers diets containing yeasts was reported by Yalçın et al [20] and Yıldız et al [21] . Seyidoğlu and Galip [22] and Seyidoğlu et al [23] were conducted to evaluate the effect of Saccharomyces cerevisiae on the serum biochemical parameters in rabbits. The diets with the yeast reduced serum HDL cholesterol and triglycerides on the 90 th feeding day.…”
