sheep month
4.Adopted 3×3 Latin square design, three five-month age fistuiated sheep were fed with concentrates which main protein sources came from DB, DBS and HND in three periods.
5.The experiment is to let suffer the person that try to be in first lab Morpheus 5 hours, yu Qingchen 4 when wake up 30 minutes get up, make watch card of a group of line drawing, what draw on these card is the thing that daily visibility goes to, and so on of such as day, month, star, garment, shoe, cap, cat, dog, sheep, after card lets suffer the person that try to be watched twice, ask they draw up by memory had seen thing of a few what.
6.Nine three month old little?fat?tail sheep were randomly divided into 3 groups for gas and energy metabolism trial?In each group there were one wether hogg and two ewes lambs?The trial showed when the diatary metabolizable energy concentration was between 2300 to 2700 kcal/kgDM and the total metabolizable energy intake was between 2600 to 4800 kcal/d,the amount of CH?4 gas output was 24～33L/d and the CH?4 energy loss was 220～310kcal/d,the ratio of methane to total energy intake were 6%～9%,The methane concentration in exhaled gas was 0?10%～0?17%?The regression equations of CH?4 and total energy intake were as follows:in period 3～5months:CH?4(L/d)=8?7106+0?0052x;
