ÖZETDoğu-Anadolu Kırmızısı ırkı, Türkiye sığırlannm %28'2 sini teşki/eder. Bu ırkın süt verimleri, ağız ve normaı süt/erinin bi/eşifPi,süt yağlarmın fiziksel ve kimyasal (izeiliklerini, belirtmek gayesi ile buaraştırmaya girişi/miştir.Doğu Anadolu KımlZlsı ırkı süt verimi; lzmen (11/178) tarafindanmemleketimizin dnemli iki yerli, ırkı olan yerli Karalarda yıllık 842kg. günlük 3.46 kg ve Boz ırkta (l0/29) 655 kg. (yıllık) ve 3.9 kg. (günlük)olarak tesbit edilen verimlerden (inemli dlçüde yüksek bulunmuştur.Atatürk Universitesi Çiftliği ve köy şartlarındaki gruplar arasında sütverimi bakımından bire iki misli (1414 ve 711 kg.) fark giirü1milştür.Laktasyon müddeti de 1. grupta diğerinden uzundur. Buradan DoğuKırmızlSı ırkmda süt veriminin bi/gili bakım ve besleme ile artınlabileceğisonucu çıkmaktadır.lki deneme grubu süt bileşimleri arasındaki farklar istatistikfbakımdan %5 seviyesinde önemli bulunmamıştır. Süt yağı konstantlarıarasında Polenske sayıları hariç diğerleri arasındaki farklılık önemlideğildir.A STUDY OF MİLK YİELD, MİLK COMPOSİTİON, FİZİCAL ANDCHEMİCAL CONTANTS OF BUTTERFAT OF THE EASTERN-RED COWS.The Eastem Red Breed is thedominant and typical race of the sameregion. The Cows selected fromamong the cows of Atatürk Üniversityfarm and from among the cows wheregrown up under normal village condition.This inve~tigation have been carriedout to defermine the milk yield,composition of the normal milk andcolostrum, physcal and chemical contentsof butter fat. The results o[ theresearch are as follows.1- The milk yield of farm groupvaried from 603 - 2510 kg. and averagewas 1414, 790 kg. The annual milk yieldof village group varied from 552 868kg. with the average of 7i 1,517±31 kg. The lactation peryot is deterrninedas 236 days.2- The compasition of collostrummilk varied to a great deal for firtstwo and three days. The compasitionof colostral milk of the farm groupand village group was found to beclose similar to each other.3--The compasition of Red-Cowsnormal milk are as follows:a- Dry matter content varied from12,3978 to 15,5575 %with an averageof 13.2747±O.l968 % for farm groupand from 11.9613 % to 14.8858 %for village group. General averagewas found to be 13.4517 %'b- The water cantent varied from84.4425 to 87.6023 % with an averageof 86.8253 %for the farnı cows and forvillage cows from 85.1142 to 88.0387.%with an average of 86.4962±O.l942.Combined average was found to be86.5483±02227 %'c- Fat content varied between3.0656 and 6.7000 % with an averageof 4.0067±0.1991 % for larm cowsand 2.9450 to 5.4938 %with an averageof 4.481O± 1.7325 % for village cows.Combined average of both groUp was4.3450±0.2075 %'d- Non fat dry matter content variationrange was from 8.7950 to 9.6375 %, with an average of 9.1680±0.0492 % for farın group and 8.66399.8938% with an average of 9.0228±0.2870 % for village groups. Generalaverage was found to be 9.l067±0.0523 %'e- Protein content varied from 2.924& to 3.7894 % with an average of3.3İ95±0.0536 for farm group andfrom 2.5029 to 4.0507 % with an average3.1327±0.1007 for village cows.The combined average calculated to be3.2839±0.865 %'f- Laetose cantent: The generalaverage was 5.0967±0.1023 %, varyingfrom 4.3515 to 5.5604 % for[arrn group with an average of 5. 1182+0.0782 % and from 3.9971 to 5.7756% for viIIage group with an avrage of5.1822±0.1177 %'g- Specific Gravity varied from1.0300 to 1.0345 for farrn group withan average of i .0320±0.00 and from1.0293 to for village group with anaverage of 1.0312±0.00.
