Effects of some environmental factors on somatic cell count and milk chemical composition in cow bulk tank milk
Öz: The aim of our research was to determine theinfluences of some environmental factors on somaticcell count (SCC) and chemical composition of cowbulk tank milk. A total of 428 bulk tank milk samplesof Brown Swiss cows were collected betweenJanuary and October 2016 from family dairy farmslocated in Kırşehir province of Turkey. To evaluatethe effect of farm scale, daily total bulk tank milkproduction was classified in three groups (small: <20lt/d; medium: 20-40 lt/d and large: >40 lt/d). Also,three groups were designed according to averageSCC values as low (<200x103 cells/ml), medium(200-500x103 cells/ml) and high SCC (>500x103cells/ml). SCC was transformed according to thebase of log10, because it did not show normaldistribution. The results showed that samplingseason was significantly affected fat content(P<0.05), logSCC, solids-not-fat (SNF), protein,lactose and pH (P<0.01). SCC was the highest inlarge-scale farms, while the highest fat content wasdetermined in small-scale farms (P<0.01). Also, thelowest pH was found in large-scale farms comparedto small and medium-scale farms (P<0.01). Of allbulk tank milk composition, SCC only affected fatcontent (P<0.05), and the lowest fat content wasdetermined in bulk tank milk with high SCC(>500x103 cell/ml). As a result, it was concluded thatseason was primarily responsible among the mostimportant environmental factor to increase bulktank milk quality

Öz: Araştırmamızın amacı, somatik hücre sayısı (SHS) ve inek tank sütünün kimyasal bileşimi üzerine bazı çevresel faktörlerin etkilerini belirlemektir. Türkiye'de Kırşehir ilinin bulunan aile tipi süt sığırı işletmelerinden Ocak ve Ekim 2016 tarihleri arasında Esmer ineklerden toplam 428 adet tank inek sütü örneği toplanmıştır. İşletme ölçeğinin etkisini değerlendirmek için, günlük tank sütü üretimi üç grupta sınıflandırıldı (küçük: <20 lt/g; orta: 20-40 lt/g ve büyük: >40 lt/g). Ayrıca, ortalama SHS değerlerine göre düşük (<200x103 hücre/ml), orta (200-500x103 hücre/ml) ve yüksek SHS (>500x103 hücre/ml) olarak üç grup oluşturulmuştur. SHS normal dağılım göstermediği için log10 tabanına göre transforme edilmiştir. Sonuçlar, örnek alma mevsiminin yağ oranı (P<0.05), logSHS, yağsız kuru madde (YKM), protein, laktoz ve pH'ı (P<0.01) önemli ölçüde etkilediğini göstermiştir. SHS büyük ölçekli işletmelerde en yüksek iken, en yüksek yağ oranı küçük ölçekli işletmelerde belirlenmiştir (P<0.01). Ayrıca, en düşük pH küçük ve orta ölçekli çiftliklere kıyasla büyük ölçekli işletmelerde bulunmuştur (P<0.01). Tüm tank sütü bileşimlerinden, SHS yalnızca yağ oranını etkilemiş (P<0.05) ve en düşük yağ oranı yüksek SHS (>500x103 hücre/ml) olan tank sütünde belirlenmiştir. Sonuç olarak, mevsimin tank süt kalitesini artırmak için öncelikle en önemli çevresel faktörlerden biri olduğu sonucuna varılmıştır.
