摘要
对河曲藏獒初生、断奶、3月龄、6月龄、12月龄、18月龄、24月龄体质量和体尺进行了测定和分析。结果表明:河曲藏獒公犬体质量从3月龄开始极显著地大于母犬(P<0.01),体高从12月龄开始极显著地大于母犬(P<0.01),胸围只在6月龄极显著大于母犬(P<0.01)。在其它生长阶段中,公母犬间无明显差异(P>0.05)。河曲藏獒有较高的平均日增重,公、母犬最大日增重分别为220.66 g,193.66 g,12月龄体质量分别为48.80 kg,44.65 kg。在断奶到6月龄期间加强对藏獒幼犬培育十分重要。
At different stages of individual growth of the Hequ population of the Tibetan Mastiff from birthday to 24-month-age, the body weight and size(BW, BS) were measured and analyzed. The results indicated that the BWs in the male group (MG) were significantly larger than those in the female group (FG) from 3-month-age to 24-month-age(P<0.01), the withers heights(WHs) from 12-month-age in MG shown higher than those in FG (P<0.01), and the heart girth were different (P<0.05) only at 6-month between MG and FG. None of others was different between MG and FM(P>0.05). The gain in weight per day in MG (220.66 g) or FG(193.66 g) were the greatest during the period of 3-6 month-age. The BW in MG or FG was up to 48.80 kg or 46.65 kg at 12-month-age, respectively.
