Abstract
Bu çalışma süt ineklerinde Saccharomyces cerevisiae canlı maya kültürünün rumen protozoalarının sayı ve yüzde dağılımlan ile rumen sıvısı pH, sodyUm. (Na}, potasyum (K} ve Toplam Uçucu Yag Asidi (TUY A) miktarlan üzerine etkisini incelemek amacı ile gerçekleştirildi. Çalışmada aynı yaş ve süt verimine sahip toplam 24 baş Esmer ve Holstein ırkı süt inegi kullanıldı. Deneme boyunca hayvaniara konsantre yem ve bezelye silajı yedirildi. Deneme grubunun rasyonuna hayvan aş ına 1 O g canlı maya kültürü (Saccharomyces cerevisiae) ilave edildi. Çalışma ilk iki haftası adaptasyon olmak üzere toplam 10 haftalık bir dönem boyunca devam etti. Denemenin 1., 30., ve 60. günlerinde, sabah yemiernesinden 3 saat sonra, kontrol (K) ve deneme (Sc) grubu hayvanlardan rumen içerigi alınarak pH, protozoon sayısı ve identifıkasyonu, TUY A ve ruınen sıvısı Na+ ve K+ ' u yönlerinden incelendi. Protozoa sayısı 30. günde Sc grubunda (122082.3 ± 8117.8 mr\ n=12) K grubundan (50694.8 ± 2120.5 ml -ı, n= J2) daha yüksek (p<O. 05) bulunurken, rumen sıvısı K+ miktarı ise 60. günde Sc grubunda (23.88 ± 2.58 ınEq , n=12) K grubundan (26.42 ± 2.39 mEq/1, n=l2) düşük (p<0.05) bulundu. Rumen ıvı ında incelenen diğer parametreler açısından K ve Sc grupları arasında istatistiksel bir farklıhga rastlanmadı. Çalışınada hem K hem de Sc grubunda Holotricha (Isotricha prostoma, lsotricha intestinalis, Dasytricha ruminantium) ve Oligotricha (Entodinium spp, Epidinium spp, Diplodinium spp, Polyplastron multivesiculatum, Ophyroscolex caudatum) sınıfına ait farklı protozoon türleri belirlendi. İncelenen parametreler açısından Saccharomycess cerevisiae canlı maya kültürünün süt ineği rasyo nlarına katılmasının ruınen sıvısı değerleri üzerine önemli etkisinin olınadıgı kararına varıldı
This study was carried out to investigate the effect of Saccharomyces cerevisiae on protozoa counts and percentage, pH, Na+, K+ and Total Volatile Fatty Acid (TVFA) of ruminal fluid in dairy cattle. In this experiment, twentyfour Brown Turkish and Holstein dairy cows with the same age and mi lk yield were used. The cows were fed on concentrate and peas silage during experimental period. The ration of the experimental group animals was added 10 g live yeast culture (Saccharomyces cerevisiae) per head. The study lasted for ten weeks, two of which were for adaptatjon. At the 1 'st, 30' th and 60'th day of the experiment 3 hours after morning feeding ruminal fluid content were taken from the control and experimental group aniınal s and samples were tested for pH, protozoa counts and identifıcation, total volatile fatty acids (TVF A), Na+ and K+ values.
