Abstract

This study was conducted to investigate the effects of defaunation, and the addition of urea and sulfur in the replacement of plant protein (PP) sources on concentrations of Na, K, Zn and Fe in the ruminal fluid, blood plasma and wool of lambs. Forty male Ramlic lambs, 2.70 ± 0.30 months of age, and weighing approximately 16.44 ± 0.41 kg, were used. Lambs were divided into 4 groups as follows: faunate + control diet (FC), defaunate + control diet (DC), faunate + experimental diet (FE), and defaunate + experimental diet (DE). The control diet contained plant protein as a N source, whereas the experimental diet was supplemented with urea and sulfur, both at 3% of BW per day. The forage portion of the diet was 350 g of alfalfa hay per lamb per day. Diets were fed twice daily in equal amounts. Defaunation, or feeding a diet supplemented with urea and sulfur in place of plant protein sources, had no effect on ruminal fluid Na concentrations but there was an interaction on Na concentration in the rumen fluid. Ruminal K concentration was lower (P < 0.021) in the experimental diet versus the control diet, while it was not affected by defaunation. There was an interaction effect on Zn concentration in rumen fluid. Plasma Na, K and Zn concentrations were not affected by treatments, whereas defaunation significantly decreased (P < 0.048) plasma Fe concentration. Defaunation or N source had no effect on Na, K, Zn and Fe concentrations in wool. We concluded that both defaunation and feeding a diet supplemented with urea and sulfur in place of plant protein sources did not affect blood plasma, except for Fe, and wool Na, K, Zn and Fe concentrations despite differences in their ruminal concentration.

Özet

Bu çalışma, defaunasyon işlemi ile rasyona bitkisel protein kaynağı yerine üre ve kükürt ilave edilmesinin kuzularda rumen sıvısı, plazma ve yapağılarındaki Na, K, Zn ve Fe düzeylerine etkilerini belirlemek amacıyla yapıldı. Çalışmada; ortalama 2,70 + 0,30 aylık, 16,44 ± 0,41 kg canlı ağırlığa sahip 40 adet erkek Ramlıç kuzu kullanıldı. Kuzular faunalı kontrol rasyon (FK), defaunalı kontrol rasyon (DK), faunalı deneme rasyon (FD) ve defaunalı deneme rasyon (DD) olmak üzere dört gruba bölündü. Azot kaynağı olarak, kontrol rasyonu bitkisel protein içerirken deneme rasyonu üre ve kükürt içerdi ve her iki rasyon da hayvanlara canlı ağırlıklarının % 3'ü oranında verildi. Kaba yem olarak her kuzuya günlük 350 g yonca kuru otu verildi. Yemleme eşit miktarda günde iki kez yapıldı. Araştırmada; defaunasyonun veya bitkisel protein kaynağı yerine üre ve kükürt ilave edilen rasyonla beslemenin, rumen sıvısındaki Na düzeylerine etki etmediği bunun yanında, rumen sıvısı Na düzeyi bakımından uygulamalar arasında bir etkileşimin olduğu tespit edildi. Rasyondaki azot kaynağı rumen sıvısı K düzeyini etkilerken (P < 0,05), defaunasyonun ise söz konusu parametreyi etkilemediği bulundu. Rumen sıvısı Zn düzeyi bakımından uygulamalar arasında bir etkileşim olduğu tespit edildi. Araştırmada; plazma Na, K ve Zn düzeylerinin uygulamalardan etkilenmediği, defaunasyonun ise plazma Fe düzeylerini önemli oranda azalttığı tespit edildi (P < 0,05). Sonuç olarak; defaunasyonun ve rasyona bitkisel protein kaynakları yerine üre ve kükürt ilave edilmesinin, rumen düzeylerindeki farklılığa rağmen, plazma (Fe hariç) ve yün Na, K, Zn ve Fe düzeylerini etkilemediği tespit edildi.
