Growth performance of 168 Awassi (A), Morkaraman (M), Tushin (T) purebred lambs and their crosses AxM, MxT, AxM and TxM reared under semi-intensive management in Turkey were evaluated. The lambs grazed on pasture for 84 days and were provided with a concentrate diet (1.5-2.0% of their live weight). Birth weight and average daily weight gain during the pre-grazing period for M, A, T, MxT, AxM and TxM crossbred lambs were 2.91, 3.61, 3.70, 4.30, 2.63, and 3.79kg and 186, 129, 160, 160, 163, and 168g, respectively. Corresponding estimates were 20, 15, 15, 17, 20 and 19kg for initial fattening weight; 168, 169, 160, 176, 174 and 184g for average daily weight gain on fattening, and 34, 30, 28, 32, 35, and 34kg for final fattening weight, respectively. The amounts of concentrate consumed per kg weight gain in addition to grazing on pasture for purebred and crossbred lambs were 1.89, 1.86, and 1.97 and, 1.78, 1.82, and 1.71kg, respectively. The genotype of lamb and type of birth significantly affected the birth weight. Besides the genotype and the type of birth, age of dam and sex had a significant influence on the average daily weight gain during the pre-grazing period. Average daily weight gain during the fattening period was significantly affected by sex.

土耳其半精养管理下纯种 Awassi、Morkaraman 和 Tushin 羔羊及其杂交的生长性能

评估了在土耳其半精养管理下饲养的 168 只 Awassi (A)、Morkaraman (M)、Tushin (T) 纯种羔羊及其杂交 AxM、MxT、AxM 和 TxM 的生长性能。羔羊在牧场上放牧 84 天，并提供浓缩饲料（其活重的 1.5-2.0%）。M、A、T、MxT、AxM和TxM杂交羔羊的出生体重和平均日增重分别为2.91、3.61、3.70、4.30、2.63和3.79kg和186、129、160、160、160分别为 163 和 168 克。相应的初始育肥体重估计为 20、15、15、17、20 和 19 公斤；育肥期平均日增重分别为 168、169、160、176、174 和 184g，最终育肥体重分别为 34、30、28、32、35 和 34kg。纯种和杂交羔羊除了在牧场放牧外，每公斤增重消耗的精料量分别为 1.89、1.86 和 1.97 公斤，以及 1.78、1.82 和 1.71 公斤。羔羊的基因型和出生类型显着影响出生体重。除了基因型和出生类型外，母猪年龄和性别对放牧前的平均日增重也有显着影响。育肥期间的平均每日增重受性别影响显着。
