Effects of Saccharomyces cerevisiae and Spirulina platensis on Growth Performances and Biochemical Parameters in Rabbits

Abstract

A feeding trial was conducted to evaluate the effect of live yeast culture Saccharomyces cerevisiae (SC) and Spirulina platensis (SP) on the growth performance and serum biochemical parameters in rabbits. Forty, male New Zealand white rabbits, aged 5-6 weeks, were studied in 4 groups. The groups; I. Control (basal diet), II. SC (added 3 g/kg diet), III. SP (added 5% of the diet), IV. SC and SP (added 3 g/kg SC and 5% SP of the diet), respectively. The experiment lasted for 90 days. Blood samples were obtained by ear venipuncture on the 90 th day. Also final body weight, total weight gain, total feed intake and feed conversion ratio were evaluated at the each month of the 90 th day trial. There were no significant differences occurred in growth performances and biochemical parameters, but serum globulin value decreased and albumin globulin ratio increased in SP and SC+SP groups (P<0.05). More studies would be necessary to elucidate the effects of supplementing spirulina on growth and determine the optimum dietary concentration in animals. Keywords: Rabbits, Saccharomyces cerevisiae, Spirulina platensis, Growth performance, Serum biochemical parameters Tavşanlarda Saccharomyces cerevisiae ve Spirulina platensis'in Büyüme Performansı ve Serum Biyokimyasal Parametreleri Üzerine Etkileri ÖzetBu araştırma canlı maya kültürü Saccharomyces cerevisiae (SC) ve Spirulina platensis (SP)'in tavşanlarda büyüme performansı ve serum biyokimyasal parametreleri üzerine etkilerini değerlendirmek için yapıldı. 40 tane, 5-6 haftalık beyaz Yeni Zelanda tavşanı 4 gruba ayrıldı. Gruplar sırasıyla; I. Kontrol (bazal diyet), II. SC (3 g/kg yeme ilave edildi), III. SP (%5 oranında yeme ilave edildi), IV. SC ve SP (SC 3 g/kg ve SP %5 oranında yeme ilave edildi) olarak belirlendi. Çalışma 90 gün sürdü. 90. gün sonunda kulak venasından kan örnekleri toplandı. Ayrıca, doksan günlük çalışmada her ay, son canlı ağırlık ile toplam canlı ağırlık artışı ve toplam yem tüketimi ile yemden yaralanma değerlendirildi. Büyüme parametreleri ve biyokimyasal parametrelerde önemli farklılık bulunamadı fakat SP ve SC+SP gruplarında serum globulin değeri azaldı ve albumin-globulin oranı ise arttı (P<0.05). Spirulina ilavesinin büyüme performansı üzerine olan etkilerini aydınlatmak ve hayvanlarda en uygun diyet konsantrasyonunu belirlemek için daha fazla çalışmaya gereksinim vardır.

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.…”

The Effect of Symbiotic Drenching Mixture on the Ingestive Behavior, Productive Performance, Blood Biochemical Parameters and Carcass Traits of Growing Rabbits

“…The results were in compliance with the finding of Abdel-Khalek et al (2012) who studied the effect of two levels (1 and 1.5% EM) of microorganisms supplementation (EM1) for growing New Zealand White rabbit (7 weeks of age) and found an increase in concentration of total protein, albumin, globulin and glucose in the group fed 1.5% EM1treatment. Seyidoglu and Galip (2014) reported a non-significant increase for blood glucose for those received S. cerevisiae (3 g/kg diet) from control. Moreover, Sarat Chandra et al (2015) reported that there was non-significant increase in blood glucose level for rabbits when fed with probiotics (Saccharomyces boulardi 50% and Pediococcus acidilacticii 50%, 109 CFU/g of feed) and enzymes (Kemzyme HF at 500 g/Ton of feed).…”

“…On contrary, Dorra et al (2013) stated that use of dietary organic acids did not significantly influence growth performance, carcass traits or blood parameters of New Zealand White × California experimental rabbits, moreover Seyidoglu and Galip (2014) observed that final body weight and total weight gain was not affected significantly (P>0.05) for a period of 90 days when male New Zealand White rabbits (aged 5-6 weeks) raised on supplemented diet with live yeast culture. There was no significant difference between means (P > 0.05).…”

A Prominent Superfood: Spirulina platensis

“…There are many different studies that point out the growth performance of S. platensis in animals [50][51][52][53][54][55][56][57]. For example, Moreira et al [50] studied the Wistar rat using S. platensis as an added nutrient at 8.8, 17.6, and 26.4% doses of forage.…”

“…On the other hand, although some researchers found positive effects of S. platensis as a supplement with fish [52], some of them reported no significant changes in growth performances in fish [53,54]. Seyidoglu and Galip [51] tried to elucidate the effects of S. platensis on growth performance in rabbits. They indicated that there was a positive effect of supplementing S. platensis on growth performance due to dose, animals, and environmental changes.…”
