Monitoring of somatic cell count variations during lactation in primiparous and multiparous Turkish Saanen goats (Capra hircus)

Öz:
Bu çalıșmada, 14’ü ilk laktasyonunda (primiparous), 14’ü de 2. ya da daha sonraki laktasyonunda (multiparous) olmak üzere toplam 28 baș Saanen ırkı keçi kullanıldı. Bireysel süt örnekleri, 7 aylık laktasyon süresince 2 haft ada bir sabah ve akșam alındı. Her iki grupta da (primiparous, multiparous) somatik hücre sayısı (SHS) akșam sağımında daha yüksek iken (840,40 vs. 532,30 hücre mL−1; 1050,40 vs. 759,70 hücre mL−1), süt verimi daha düşük bulundu (115,40 vs. 193,80 kg; 177,40 vs. 280,00 kg). Laktasyon sırası, laktasyon süresi hariç diğer değișkenleri önemli düzeyde etkiledi. Primiparous keçiler multiparous keçilere göre daha düșük süt verimine ve SHS na sahipti. Primiparous ve multiparouskeçiler için ortalama SHS, logaritmik SHS, laktasyon süresi ve süt verimi sırasıyla 686,40 × 106 hücre mL−1, 905,10 × 106 hücre mL−1 (P < 0,05); 5,81, 5,94 (P < 0,05); 203,33, 207,58 gün (P > 0,05) ve 309,20, 457,40 kg (P < 0,05) dır. Numunlerdeki SHS, özellikle laktasyonun son dönemlerinde PMO (Pasteurized Milk Ordinance) tarafi ndan bildirilen 1 × 106 mL−1 değerinin üstünde olmasına rağmen, genel SHS ortalaması PMO limitin altındaydı. SHS, süt verimi ile negatif korelasyona sahipti fakat korelasyon katsayısı istatistiksel önemde bulunmadı (P > 0.05). Laktasyon ilerledikçe her iki grupta da SHS artarken süt verimi azaldı. Bu çalışmadan elde edilen sonuçlar, Türkiyede kabul edilebilir bir keçi sütü SHS standartının geliştirilmesi için kullanılabilir.

İlk ve daha sonraki laktasyonlarındaki Türk Saanen keçilerinde (Capra hircus) laktasyon süresince somatic hücre sayısının değişimi

Öz:
In this study, a total of 28 Saanen does were used to evaluate the relationship between somatic cell count (SCC) and milk yield. Th e study included 14 fi rst-lactation (primiparous) does and 14 does in second lactation or greater (multiparous). Individual milk samples from both morning and evening milkings were taken every 15 days throughout the lactation period of 7 months. While somatic cell counts were higher during the evening milking (840.40 versus 532.30 cells mL&#8722;1; 1050.40 versus 759.70 cells mL&#8722;1), milk yields were lower during the evening milking (115.40 versus 193.80 kg; 177.40 versus 280.00 kg) for both primiparous and multiparous goats. Parity of the does aff ected the variables signifi cantly, except for days in milk. Primiparous does had lower milk yields and SCCs than multiparous does. Overall, the mean SCC, logarithmic SCC, days in milk, and milk yield were 686.40 × 106 cells mL&#8722;1 and 905.10 × 106 cells mL&#8722;1 (P < 0.05), 5.81 and 5.94 (P < 0.05), 203.33 and 207.58 days (P > 0.05), and 309.20 and 457.40 kg (P < 0.05)per doe per lactation, for primiparous and multiparous goats, respectively. Goat milk samples contained high SCCs and exceeded the requirement of 1 × 106 mL&#8722;1 of the Pasteurized Milk Ordinance (PMO) during most of the late lactation stages; however, the overall SCC mean was under the PMO limit. Th e SCC was negatively correlated with milk yield, but the correlation coeffi cient was not found to be signifi cant (P > 0.05). As lactation progressed, the SCC increased and milk production decreased in primiparous and multiparous goats. Th e results of this paper could be useful for the development of acceptable goat milk SCC standards in Turkey.
