Abstract
Merada Otlayan Karayaka Koyunlarında Mevsimsel Değişimin İnce Bağırsağa Geçen Mikrobiyal-N Miktarı ve Yem Tüketimine Etkisi
Highlights
THE Karayaka sheep is one of the indigenous breeds reared on the coastline of the Black Sea region of Turkey
The objectives of the present study were to examine the microbial-N flow to the small intestine and to predict digestible organic matter intake (DOMI) in grazing Karayaka sheep on the basis of urinary excretion of PD by the use of spot urine sampling under field conditions and to investigate the effects of seasonal variation on ruminal microbial synthesis
Dry matter (DM), nitrogen (N), neutral detergent fibre (NDF), and acid detergent fibre (ADF) were determined after the grinding through a 1mm screen
Summary
THE Karayaka sheep is one of the indigenous breeds reared on the coastline of the Black Sea region of Turkey. The breed is mainly kept for its high meat quality because its milk production is lower than other native breeds. Karayaka sheep are well adapted to the wet climate of the region and there is a total population of approximately one million [1]. The quality of grazing in the areas of its distribution is much better than in most of the other regions and the grazing season is longer. The use of spot urine sampling has been proposed to predict protein nutrition and digestible organic matter intake in grazing sheep [2] and goats [3]. Microbial protein flow to the small intestine has been estimated total of purine derivatives
