Abstract

This study aimed to determine the chemical composition and mineral contents of Awassi ewes' milk during lactation. Morning milks of 150 Awassi ewes were taken once a week during 18 weeks of lactation. Mean values obtained from analyses of the ewes' milk samples were 17.54% ± 1.35 for dry matter; 6.61 % ± 1.33 for fat; 10.93% ± 0.44 for non-fat dry matter; 5.68% . ± 0.48 for protein; 4.34% ± 0.27 for lactose and 99.05 ± 11.63 kcal/lOO g for energy value; 0.149% ± 0.008 for titratable acidity; 6.72 ± 0.42 for pH; and 1.0334 ± 0.001 g/cm3 for specific gravity. The contents of calcium, phosphorus, potassium, magnesium and sodium of the samples were 395.2 ± 97.58 mg/100 g, 138.7 ± 22.38 mg/100 g, 119.9 ± 36.54 mg/100 g, 19.5 ± 1.65 mg/100 g, and 74.3 ± 11.75 mg/100 g, respectively. Results of the statistical analyses indicated significant lactational effects on the contents of dry matter, fat, and sodium (P. < 0.01) and energy value, pH, titratable acidity, and specific gravity (P < 0.05).

Özet

Bu çalışmanın amacı laktasyon dönemi boyunca Awassi koyun sütlerinin bileşim ve mineral içeriğinin belirlenmesidir. Laktasyon dönemindeki 150 İvesi koyunundan haftada bir kez olmak üzere 18 hafta boyunca sabah süt örnekleri alınmıştır. Analiz sonuçlarında koyun sütlerinin bileşimleri ortalama olarak; kurumadde % 17,54 ± 1,35, yağ % 6,61 ±1,33, yağsız kurumadde % 10,93 ± 0,44, protein % 5,68 ± 0,48 , laktoz % 4,34 ± 0,27 ve enerji değeri 99,05 ±11,69 kcal/lOOg, titrasyon asitliği % 0,149 ± 0,008, pH 6,72 ± 0,42 ve özgül ağırlık 1,0334 ± 0,001 g/cm3'tür. İncelenen süt örneklerinin kalsiyum, fosfor, potasyum, magnezyum ve sodyum içerikleri sırayla 395,2 ± 97,58, 138,7 ± 22,38 119,9 ± 36,54, 19,5 ± 1,65 ve 74,3 ± 11,75 mg/100 g olarak belirlenmiştir. Yapılan istatistiksel analiz sonucu laktasyon döneminin koyun sütlerinin kurumadde, yağ, sodyum değerlerine (P < 0,01) ve enerji değeri, pH, titrasyon asitliği, özgül ağırlık değerlerine (P < 0,05) etkisi önemli çıkmıştır.
