【摘要】：為了探索昌臺牦牛種質(zhì)資源特性,詳細(xì)了解昌臺牦牛的生長發(fā)育性能,試驗(yàn)采用對昌臺牦牛各個年齡組牛只的體尺體重進(jìn)行測定。結(jié)果表明:公、母昌臺牦牛的初生重分別為(12.44±2.53)kg、(11.67±1.75)kg,1.5歲、2.5歲、3.5歲、4.5歲及成年公牦牛的體重分別為99.90 kg、101.65 kg、216.10 kg、220.16 kg、355.97 kg,母牦牛分別為101.65 kg、162.34 kg、194.00 kg、192.95 kg、252.61 kg。昌臺牦牛生長發(fā)育在3.5歲之前相對較快,3.5~4.5歲增長較為平緩,與其他牦牛的生長發(fā)育性能相一致。
