Abstract:The digestion and metabolism experiment was carried out on the basis of HH91 and Pluto rye in chicken. The results showed that average weight gain of chickens had a decreasing tendency compared with the control. The detected average weight gain (the control) were 27.41% (15% HH91), 28.96% (30% HH91), 34.75% (45% HH91), 20.85% (15% Pluto), 28.19% (30% Pluto) and 42.09% (45% Pluto), respectively. There was no difference (p>0.05) in the apparent digestibility of dry matter, organic material, crude protein, nitrogen-free extract, and gross energy between the control and the other groups administrated with rye. But the apparent digestibility of crude fat and crude fiber had a decreasing tendency (P<0.05). No significant differences were found in other aspects except crude fat (p<0.05) and crude fiber (p<0.01). When the addition of rye was less than 30%, all the apparent digestibility of the nutrients had almost no difference with the control group except that of the crude fiber.
