Digestibility of diets contained imported and local concentrates with chromium oxide and lignin as markers in the Turkmen horses

The aim of this research was to compare the digestibility of two concentrates with chromium oxide (Cr2O3) and lignin as markers in the Turkmen horses. In a completely randomised experiment 16 Turkmen horses, weighting 433 ±50 kg and aged 8 ±3 years were used. The treatments were a control diet (Tc) contained 25 percent of imported concentrate and three diets contained 20, 25 and 30 percent of local concentrate, T1, T2 and T3 respectively. The trial was carried out for a period of 28 days, started with 21 days of adaptation period and 7 days sampling and data collection. When Cr2O3 marker was used, the digestibility of OM (547 vs. 506), CP (545 vs. 527) and NDF (427 vs. 309) were higher (P
