Abstract (2. Language): 
Usage area of some feed additives is on the rise in parallel to increasing world population and devel-oping dairy cattle industry. Transition period (approximately three weeks each before and after calving) is clear-ly the most important period of a dairy cow’s life cycle, by reason of a large number of metabolic and reproduc-tive disorders are occurred in the transition period. In growing dairy cattle industry it is more important to pre-vent metabolic and reproductive disorders than treating them. Especially for preventing fatty liver syndrome which is generally occurred in transition period and resulted with excessive costs of treatment, addition of rumen protected choline to high yielding dairy cow rations seems to be a promising nutrition strategy.
Abstract (Original Language): 
Artan dünya nüfusu ve gelişen süt sığırcılığı endüstrisine paralel olarak, süt sığırlarının beslenmesinde yem katkı maddelerinin kullanım alanı ve miktarı artmıştır. Metabolik ve reprodüktif bozuklukların en çok göz-lendiği dönem, doğum öncesi ve sonrasındaki 3 haftayı kapsayan geçiş dönemidir ve bu süreç, bir süt sığırının yaşam döngüsü içerisindeki en önemli dönem olarak kabul edilmektedir. Günden güne büyüyen süt sığırcılığı endüstrisinde hastalıkları tedavi etmekten çok hastalığın ortaya çıkışını önlemek önem kazanmıştır. Büyük verim kayıplarına ve tedavi maliyetlerine yol açan özellikle geçiş döneminde gözlenen yağlı karaciğer sendromunun önlenmesinde, geçiş dönemindeki yüksek verimli süt sığırı rasyonlarına rumenden korunmuş kolin ilavesi umut verici bir besleme stratejisi olarak değerlendirilmektedir.
