Şam ve Kilis Keçilerinde Sağım Öncesi Dinlendirmenin Bazı Süt Verim Özellikleri Üzerine Etkileri

Bu çalışma Şam ve Kilis keçilerinde sağım öncesi dinlendirmenin bazı süt verim özellikleri üzerine etkilerinin belirlenmesi amacı ile yapılmıştır. Çalışmada iki ırkın süt verim özellikleri karşılaştırılmıştır. Her iki genotip grubundaki keçiler kontrol (10 baş) ve uygulama (10 baş) olarak iki alt gruba ayrılmışlardır. Tüm keçiler gün boyu, bölgedeki geleneksel yetiştiriciliğe uygun olarak aynı merada otlatılmışlardır. Keçilere, ağıla döndüklerinde kuru maddede, %16 ham protein ve 2600 kcal metabolize enerji içeren kesif yemden hayvan başına 1 kg verilmiştir. Kontrol grubu keçileri kesif yemi yerken el ile sağılmışlardır. Uygulama grubu keçiler ise kesif yem yedikten sonra bir saat dinlendirilmiş ve daha sonra el ile sağılmışlardır. Çalışma sonunda, süt verimi ve kompozisyonu üzerine, laktoz içeriği hariç (P<0.01), ırkın ve uygulamanın etkisi önemsiz bulunmuştur (P>0.05). Ayrıca, sütteki tüm yağ asitlerinin içeriği üzerine laktasyon aylarının etkisi önemli bulunmuştur (P<0.05).

Anahtar Kelimeler:

Effects of Pre-milking Resting on Some Lactation Characteristics of Damascus (Shami) and Kilis Goats

This study was carried out with the aim of determining the effects of pre-milking resting on some milk yield characteristics in Damascus (Shami) and Kilis goats. The milk yield characteristics of the two breeds were also compared in the study. The goats in both genotypes were divided into two groups as Control (10 heads) and Treatment (10 heads). All goats grazed at the same pasture during day-time in accordance with traditional breeding system of the region. And, they were offered 1 kg/head/day concentrate containing 16 % crude protein and 2600 kcal metabolizable energy in dry matter when they returned to the pen. The control group goats were milked by hand while they feeding the concentrate. The treatment group goats were rested an hour after concentrate feeding and then they milked by hand. At the end of the study the effect of the application and the breeds on the milk yield and milk composition were not significant (p>0.05), except for the lactose content (p<0.01). Moreover, the effect of the lactation months on the content of all fatty acids in the milk were also detected statistically important (p<0.05).
