摘  要：
[目的]对比不同饲养方式对新疆褐牛生产发育的影响。[方法]选取16月龄左右的青年新疆褐牛68头,分为散栏组和栓系组。青年牛为试验对象分别于10月、11月、12月、次年1月和2月进行体型外貌的线性评定及体尺指标测定,并定期采集血样。[结果]在两种饲养方式中自由采食散栏饲养能提高青年新疆褐牛日增重(P<0.01),散栏全期青年牛平均日增重845.58g显著高于栓系的619.11g,提高了36.58%,散栏在12、1、2月份日增重显著高于栓系,分别高出13.61%,32.32%,53.47%。散栏式饲养显著提高了青年牛血清磷含量(P<0.01),在12、1、2月份分别高出栓系组0.62%,7.89%,14.29%了,而栓系式饲养的青年牛血清磷含量逐步下降。在两组青年牛之间血清钙含量影响不大,两组血清钙差异不显著(P>0.05)。自由散栏饲养方式在全期生长中的速度较快,体斜长,胸围,胸深,胸宽,腰角宽,腰高,坐骨宽,髋宽等基本处于继续增长趋势。[结论]散栏饲养方式能显著提高青年新疆褐牛的日增重,同时还能加快其体高,胸围,体长等体尺的生长,散栏饲养血清钙、磷含量显著高于栓系饲养。

摘  要：
【Objective】To compare the effects of serum calcium and phosphorus on growth performance of young Xinjiang brown bulls in tether and casual bar.【Methods】A total of 68heads of 16months age Xinjiang brown bulls,were selected and divided into casual bar group and tethered groups.Male claves as test subjectswere measured for body conformation linear evaluation and body size indexes analysis from October to the next February,and then blood samples of these bulls were regularly collected.【Results】In the two feeding ways,ad libitum casual bar group feeding can significantly improve the ADG of youth Xinjiang brown bulls calf(P<0.01),and the casual bar group during the whole calf ADG 845.58g was significantly higher than that in tethered group(619.11g).The average daily weight gains of the casual bar group in the December,January and February showed significantly 13.61%,32.32%,53.47% higher when compared with those in the tethered group,respectively.The casual bar group feeding significantly increased the young calf serum phosphorus content(P<0.01).In February,December and January,the young calf serum phosphorus contents demonstrated 0.62%,7.89%,14.29% higher than those in the tethered group.But the tethered feeding young cattle serum phosphorus content gradually declined.There was no significant difference for male calf serum calcium content between two groups(P>0.05).Totally,the casual bar feeding mode was better in the whole growth period because several body sizes,such as body height,body length,circumference,leg circumference,rump length,waist high,sciatic wide,hip width basically kept in the continued growth trend.【conclusion】Casual bar feeding can significantly improve the young Xinjiang brown cattle's daily gain at the same time,and can accelerate the body height,heart girth and body length etc body growth,suggesting that the casual bar feeding serum calcium and phosphorus content were significantly higher than tethered feeding.
