Aydın İlinde Bir Süt Sığırı İşletmesinde Yetiştirilen Simmental ve Kırmızı-Alaca Sığırların Süt ve Döl Verimi ile Süt Kalite Özellikleri: 1. Süt ve Döl Verimi

Bu çalışmada, Aydın ilinde özel bir işletmede yetiştirilen Simmental (SIM) ve Kırmızı-Alaca (KA)sığırların döl verimi ve süt verim özellikleri belirlenmiştir. Döl verim özelliklerinden servis periyodu(SP), buzağılama aralığı (BA), gebelik süresi (GS) ve gebelik başına tohumlama sayısı (GBTS), sütverim özelliklerinden laktasyon süresi (LS), laktasyon süt verimi (LSV), 305-gün süt verimi (305- gSV), pik zamanı (PZ) ve pik süt verimi (PSV) üzerinde durulmuştur. KA ve SIM ırklarına ait SP,BA, GS ve GBTS ortalamaları sırasıyla 109,44±5,66 g ve 96,06±3,51 g, 389,16±5,70 g ve380,37±3,54 g, 279,71±0,469 g ve 284,94±0,303 g, 1,88±0,099 adet ve 1,85±0,065 adet; ırkların LS,LSV, 305-gSV, PZ ve PSV ortalamaları ise sırasıyla 333,00±5,405 g ve 322,72±3,233 g,8235,32±148,099 kg ve 7357,03±88,122 kg, 7628,78±109,148 kg ve 6938,09±64,945 kg,46,55±2,196 gün ve 44,46±1,218 gün ve 34,68±0,567 kg ve 31,47±0,314 kg olarak hesaplanmıştır.Irklar arasında önemli döl verimi ve süt verimi farklılıkları elde edilmiş olmasına karşın, SIM ve KAırklarının her ikisinin de döl ve süt vderimi bakımından iyi bir performans göstermesi işletmedebakım-besleme-barındırma-sürü yönetimi gibi çevresel faktörlerin uygun olduğu şeklindedeğerlendirilebilir.

Milk Yield, Reproduction and Milk Quality Characteristics of Simmental andRed-Holstein Cattle Raised in a Dairy Farm in Aydın Province: 1. Reproductionand Milk Yield

In this study, fertility and milk yield characteristics of Simmental (SIM) and Red-Holstein (RH) cattle raised in a private dairy farm in Aydın province were determined. For fertility traits, days open (DO), calving interval (CI), gestation length (GL) and number of inseminations per pregnancy (NIPP), for milk yield traits lactation length (LL), lactation milk yield (LMY), 305-days milk yield (305-dMY), peak time (PT) and peak milk yield (PMY) were determined. The means of DO, CI, GL and NIPP of RH and SIM breeds were 109.44±5.66 d and 96.06±3.51 d, 389.16±5.70 d and 380.37±3.54 d, 279.71±0.469 d and 284.94±0.303 d, 1.88±0.099 and 1.85±0.065; the means of LL, LMY, 305-dMY, PT and PMY were 333.00±5.405 d and 322.72±3.233 d, 8235.32±148.099 kg and 7357.03±88.122 kg, 7628.78±109.148 kg and 6938.09±64.945 kg, 46.55±2.196 d and 44.46±1.218 d, and 34.68±0.567 kg and 31.47±0.314 kg, respectively. Although, significant fertility and milk yield differences were obtained between the breeds, the favorable performances of both SIM and RH breeds in terms of all features, considered as the environmental factors such as management-feeding-housing-herd management provided to animals in the farm were also suitable.
