A comparative stud on the milk yield and milk composition of two different goat genotypes under the climate of the Eastern Mediterranean

Bu çalışmada, düşük süt verimi ve kısa laktasyon süresine sahip olan Kıl keçiye alternatif olarak Damaskus (Şam) keçileri ile Alman Alaca x Kıl keçi (G1) melezlerinin, Akdeniz şartlarındaki, laktasyon süt verimleri ve süt kompozisyonları karşılaştırılmıştır. Süt kontrolleri, 240 günlük laktasyon boyunca İCAR A4 metoduna göre 28 gün ara ile yapılmıştır. Laktasyonun 60. günündeki sütten kesimden sonra 28 gün ara ile süt örnekleri toplanmış ve süt bileşenlerinin tespiti için analiz edilmiştir. Sonuçlar iki ırkın süt verimi ve süt bileşenleri arasında istatistiksel olarak önemli farklılıklar olmadığını göstermiştir. Çalışmada, ortalama süt verimi, kuru madde, protein, yağ, laktoz ve kül içerikleri Şam keçileri ve melezler için sırası ile, 347,6 ± 19,05 ve 316,8 ± 35,61 it, 12,2 ± 0,16 ve 12,4 ± 0,28 (%), 3,5 ± 0,07 ve 3,4 ± 0,11 (%), 4,3 ± 0,12 ve 4,1 ± 0,23 (%), 3,6 ± 0,08 ve 4,2 ± 0,11 (%), 0,77 ± 0,02 ve 0,72 ± 0,03 (%), olarak saptanmıştır. Sonuç olarak Türkiye'nin Akdeniz bölgesinde keçi sütü üretimini artırmak için hem Şam keçileri hem de melezler tavsiye edilebilir. Çünkü, çalışmada her iki ırkın süt verimleri de Kıl keçi için yapılmış olan literatür bildirişlerinden daha yüksek bulunmuştur.

Doğu Akdeniz Bölgesi iklim koşullarında farklı iki keçi genotipinin süt verimi ve süt bileşenlerinin karşılaştırılması üzerine bir araştırma

Milk yields and milk compositions of 2 different goat breeds with high milk yields, the Damascus (Shami) goat and the German Fawn x Hair goat crossbred (B1), were monitored during lactation in order to evaluate their performance under Eastern Mediterranean conditions as an alternative to the Hair goat which has a low milk yield and shorter lactation period. The milk yield was recorded by the İCAR A4 method at 28-day intervals throughout the 240 days of lactation. After weaning on the 60th day of lactation, milk samples were collected at 28-day intervals and were analysed for different milk components. The results showed that there was no significant difference between the milk yields and gross compositions of these 2 goat breeds (P > 0.05). The average milk yield, and total solids, protein, fat, lactose and ash contents were 347.6 ± 19.05 and 316.8 ± 35.61 1, 12.2 ± 0.16 and 12.4 ± 0.28 (%), 3.5 ± 0.07 and 3.4 ± 0.11 (%), 4.3 ± 0.12 and 4.1 ± 0.23 (%), 3.6 ± 0.08 and 4.2 ± 0.11 (%), and 0.77 ± 0.02 and 0.72 ± 0.03 (%), for the Damascus and the crossbred, respectively. It was concluded that the breeding of both the Damascus and the crossbred should be encouraged in the Mediterranean region of Turkey in order to increase goat milk production since both breeds had higher milk yields than that of the Hair goat as reported in the literature.
