摘  要：
【目的】探索散栏式饲养与栓系式饲养方式对肉牛增重性能的影响。【方法】选择体重相近(330 kg左右)、月龄相同(12月龄)、未去势、健康无病的50头西门塔尔公牛分为两组,每组25头牛。牛散栏式饲养为试验组,栓系式饲养为对照组。预试期为30 d,正试期为120 d,分别于10、11、12、1和2月进行对体重及各项体尺指标的测定,并定期采集血样。【结果】散栏式饲养组和栓系式饲养组牛的月增重平均分别增加了33.41和31.90 kg,日增重分别为1 113.57和1 056.83 g/d,散栏式饲养组比栓系式饲养组高21.8%,组间差异显著(P<0.05);散栏饲养组牛的腰角宽、胸围、胸宽、腹围、后腿围等体尺的变化显著高于栓系组(P<0.01);血钙含量散栏组在11月差异显著(P<0.05),而10、12、1和2月两组组间无显著差异(P>0.05),散栏与栓系对西门塔尔牛血清磷含量影响不大,两组血清磷水平差异不显著(P>0.05)。【结论】与栓系式管理方式相比,散栏饲养方式更适合于提高西门塔尔牛的生产性能。

摘  要：
【Objective】The research aims to explore the influence of the two different feeding modes: casual bar and tether on performance of bull production.【Method】50 Simmental healthy and not- castrated bulls with similar weight( 330kg) and age( 12 months old) were chosen,and divided into two subgroups of 25 bulls each. The first group was the casual bar bull as experimental group,and the second group bulls were tethered as controlling group. The period of experiment was 150 d from October 2012 to February 2013. Body weight and size were measured,and their blood samples were taken 5 times in one month intervals.【Result】In the two feeding ways,the casual bar group feeding can significantly improve the ADG of Simmental bulls( P < 0. 05),and ADG 1 268. 37 g of the casual bar group during the whole bull was significantly higher thanthat in tethered group's 969. 76 g,which was improved 30. 79%; The average daily weight gains of the casual bar group in the November,December,February showed significant increase: 21. 88%,14. 58%,and 51.58%,which were higher when compared with those in the tethered group; the experimental group of hip width,chest girth,chest width,abdominal girth,thigh width and the body measurements were significantly higher than those of the control group( P < 0. 01); In November,the experimental group of serum calcium showed significant difference( P < 0. 05),but in October,December,January and February,there was no significant difference between the two groups( P > 0. 05). Casual bar and tether phosphorus content had little effect on the Simmental bull phosphorus because the two groups of phosphorus level showed no significant difference( P > 0. 05).【Conclusion】Compared with the tethered management mode,casual bar feeding mode is more suitable for improving the production performance of Simmental bulls.
