ABSTRACT
Nutritional ingredients have been known to effect on ruminant animal performances. The present study aimed to investigate the effects of replacement alfalfa hay with giant reed on nutrients digestibility and growth performances and serum biochemistry of goats in arid subtropics. Twenty-four goats average 29.70 ± 1.17 kg body weight (BW) were randomly distributed over four groups. The goats were fed four diets composed of 50.0% concentrates and 50.0% forages. The four diets formulated according to replacement of alfalfa hay with giant reed were control alfalfa hay diet (T1; 50.0% alfalfa hay) and giant reed rations (T2 20.0% alfalfa hay and 30.0% giant reed; T3 10.0% alfalfa hay and 40.0% giant reed; T4 50.0% giant reed). Nutrients digestibility, body weight, physiological parameters and serum metabolites were investigated during the study. The results indicated that the diets with high percentage of giant reed (40.0 & 50.0%) were decreased (P<0.05) the most recorded parameters compared to the control and 30.0% giant reed diets under subtropical condition. In conclusion, replacement of alfalfa hay with 30.0% giant reed could be promising of Ardi goat growth performances, feed efficiency and serum metabolites.
