Abstract

Two experiments were conducted to determine the effects of protein levels in concentrates used in nutrition of dairy goats on milk yield and composition. Each experiment was conducted between 14 * and 98 * days of lactation. In the first experiment, 34 goats were divided equally into two groups. The groups were fed on concentrates (with 2700 kcal ME/kg) containing 14 and 20 % protein (CP). Contents of dry-matter, crude protein, fat and solids-not-fat in milk of groups were 13.26, 3.43, 4.69 and 8.57 %, 8.52 % for second group. In the second experiment, 40 goats were used. The goats were divided into three groups. The groups were fed on concentrates (with 2700 kcal ME/kg) containing 14, 17 and 20 % CP. Contents of dry-matter, crude protein, fat and solids-not-fat in milk of groups were 13.36, 12.72, 12.83 % ; 3.41, 3.25 3.40 % ; 4.62, 4.11, 4.07 % and 8.84, 8.61, 8.76 % respectively. As a result, when the CP content of concentrate was increased, milk yield was increased and dry-matter and fat contents of milk were decreased. But, this effect was not significant (P>0.05) between 2 * and 3 * groups in second experiment. Therefore, it was concluded that a concentrate containing 17 % CP was more suitable for dairy goats.

Özet

Süt keçilerinin beslenmesinde kullanılan karma yemlerdeki ham protein düzeyinin süt verimi ve bileşimine olan etkilerini belirlemek için iki deneme yapılmıştır. Her deneme laktasyonun 14. ile 98. günlerini kapsamaktadır. Gruplar sırasıyla %14 ve %20 ham protein içeren karma yemlerle beslenmişlerdir. Gruplardan elde edilen sütlerin ortalama kurumadde, ham protein, yağ ve yağsız kurumadde içerikleri 1. grupta %13.26, %3.43, %4.69ve %8.37, 2. grupta %12.85, %3.30, %4.33 ve %8.52 olarak belirlenmiştir. İkinci denemede keçiler üç ayrı gruba ayrılmıştır. Gruplar 2700 kcal/ME enerji ve %14, %17: ve %20 ham protein içeren yoğun yemlerle ad-lib olrak beslenmişlerdir. Gruplardan elde edilen sütlerin ortalama kurumadde, ham protein, yağ ve yağsız kurumadde içerikleri sırasıyla 1. grupta %13.36, %3.41, %4.62 ve %8.84, 2. grupta %12.72, %3.25, %4.11 ve %8.61, 3; grupta ise % 12,83, %3.40, %4.07ve %8.76 olarak belirlenmiştir. Sonuç olarak her iki denemede de karma yemdeki ham protein içeriğinin yükseltilmesi süt verimini olumlu, kurumadde ve yağ içeriğini olumsuz yönde etkilemiştir. Fakat bu etki ikinci denemede % 17 ve %20 ham protein düzeyleri arasında istatistiki olarak önemsiz bulunmuştur(P
