Öz

Düşük gelirli üretim sistemi koşulları altındaki küçük ölçekli aile işletmelerinde yetiştirilen 1476 Jersey ineğinden elde edilen 935 birinci 607 ikinci 432 üçüncü laktasyon kaydı yaş,buzağılama ayı faktörlerinin 305 günlük laktasyon verimi değişkenliğindeki etkilerini incelemek üzere analiz edilmiştir. Sabit faktörlü GML modeli ile yürütülen varyans analizi sonucunda bu faktörlerden buzağılama yaşının(CA),ilk (P<0.05), ikinci laktasyon üzerine (P<0.05);buzağılama ayının ilk laktasyon (P<0,001), ikinci laktasyon (P<0.01), üçüncü laktasyon (P<0.05) üzerine ve Sürü faktörünün (H): ilk ikinci üçüncü laktasyon üzerine etkili olduğu (P<0.001) anlaşılmıştır. Üçyüzbeş günlük süt verim miktarındaki ortalama büyüme ikinci laktasyonda birinci laktasyondan 198 kg daha fazla üçüncü laktasyonda ise ikinci laktasyona göre 271 kg daha fazladır.Farklı fizyolojik koşullardaki ineklerden elde edilen süt verim miktarlarını karşılaştırmayı mümkün kılmak bakımından 305 günlük süt verimlerinin buzağılama yaş ve ayı nın etkilerini azaltmak için düzeltilmesi gerekir.

Study of 305- Day Milk Yield, for First Three Lactations, of Jersey Cows Under Conditions of Small Scale Family Farms

Data of 935 first lactations, 607 second lactations and 432 third lactations obtained by 1476 Jersey cows that are managed in small scale family farms, under conditions of low input production system were analyzed in order to study effects of factors: age and month of calving on variance of 305-day milk yield. Analyze of variance carried out according to a GML with fixed factors showed statistical effects of these factors – age on calving (CA): first lactation (P<0.05), second lactation (P<0.05), month of calving (CS): first lactation (P<0,001), second lactation (P<0.01), third lactation (P<0.05) and herd (H): first, second and third lactations (P<0.001). Average growth of 305-day milk yield, in second lactation was 198 kg more than first lactation, and 271 kg more in third lactation compared to second lactation. To make possible the comparison of milk yield obtained by cows in different physiological conditions, it is necessary that 305-day milk yield be adjusted in order to reduce effects of calving age and month.
