[Objective] In the Xinjiang new era from October 2012 to February 2013, agricultural and animal husbandry Co. Ltd. feedlot Yining Tuogelake village used tethered and scattered feeding methods to conduct fattening young Xinjiang brown cattle experiment. [Method] The 16-month-old young Xinjiang brown bulls were se- lected totaling 68 heads, divided into scattered group and tethered group. Male claves were taken as test subjects from October to February of following year and body conformation linear evaluation were made, followed by measurement of body size indexes and Regular collection of Blood samples. [Result] In the two feeding ways, scattered group feeding improved the ADG of youth Xinjiang brown cattle bull calf （P〈0.01）, and the whole calf ADG 845.58g was significantly higher than that in tethered group at 619.11g, increasing by 36.58%; furthermore, scattered group in the December, January and February average daily weight gain was significantly higher compared with the tethered group at 13.61%, 32.32%, 53.47%, respectively. Scattered group feeding significantly increased the young calf serum phosphorus content （P〈0.01）, higher than the tethered group at 0.62%, 7.89%, 14.29% in February, December and January respectively. But the tethered feeding young cattle serum phosphorus content gradually declined. Of the two groups, male calf serum calcium content had little effects on the serum calcium with insignificant difference （P〉0.05）. Bulls by scattered feeding method was proved faster and better in the whole growth period, in terms of body height, body length, circumference, leg cir- cumference, rump length, waist high, sciatic wide, hip width basically in the contin- ued growth trend. [Conclusion] Scattered feeding can significantly improve the young Xinjiang brown cattle＇s daily gain, and accelerate the body height, heart girth and body length etc body growth. What＇s more, scattered feeding serum calcium and phosphorus content are significantly higher than tethered feeding.
