Abstract

Rhizomys (Rhizomyidae) is a wider distribution of the precious wild animals in southern China provinces, has high medicinal value and nutritional value, is an important wildlife resources. Miscanthus, Pennisetum Rhizomys important plant feed, is also China's rich plant resources, and how to take full advantage of the resources of these plants, used for Rhizomys becomes particularly important. To three growth stages Rhizomys (rats, mice, and rats) as experimental animals as test material, Pennisetum, Miscanthus, bamboo, solid bamboo, carnation and green bamboo plants feed application of two-factor completely randomized experimental design to carry out research on the different growth stages of wintering Rhizomys different single plant feed random feed intake, weight gain, and the apparent digestibility of nutrients; application of plant feed grade index (GI value) of each plant feed quality evaluation, the GI value obtained Rhizomys various growth stages of different plant feed, and to determine the better Rhizomys growth stages of plant feed, and provide a reference for Rhizomys farming practice. The main findings are as follows: 1. On the nutrient content of the six kinds of test plants feed significance test to study the differences of the nutrient content of different plant feed. (1) of the water content of the six species feed significance test, the test results of a very significant level, indicating that the water content of the different plant feed a significant difference. Which the highest moisture content of Pennisetum 79.71%, carnation least 40.55%. (2) of the dry matter content of the six species feed significance test, the test results up to a significant level, indicating that very significant differences in dry matter content of the different plant feed. , Carnation dry matter content of the highest, 47.93% to 49.45%, Pennisetum least. (3) of the crude protein content of six species feed significance test, the test results up to a very significant level, showed that the crude protein content of the different plant feed very significant difference. Pennisetum crude protein content of the highest, at 6.32%, green bamboo least 4.32%. (4) acid detergent fiber content of six species feed significance test, the test results up to a very significant level, indicating that acid detergent fiber content of different plant feed very significant difference. Among them, the highest concentrations of acid detergent fiber of green bamboo, is 69.64%, the Pennisetum minimum, 50.30%. Significant test 2. The wintering period Rhizomys various stages of growth of the six kinds of test plants feed arbitrarily feed intake, test results up to a very significant level, indicating that different plants feed on each growth stage winter period Rhizomys winter casual mining the impact of the food intake is very significant. With Rhizomys day-old increased its the casual feed intake gradually increase, the wintering period Rhizomys various stages of growth of bamboo casual highest dry weight of feed intake, the random feed intake Pennisetum dry weight least. At random the wintering Rhizomys on the single plant feed feed intake is reduced with the increase in the water content of plant feed. Fed 6 kinds of single plant feed the wintering period Rhizomys weight change significance test, the test results up to a very significant level, indicating that different plants feed on the growth stages wintering Rhizomys weight of a significant difference. Rats and mice stage, feeding five the Mans Rhizomys weight dropped at least, rat stage, the fed-moso Rhizomys weight loss at least. Of the wintering period Rhizomys of the various stages of growth the apparent digestibility of the nutrients of the six species feed significance test to study the different growth stages of the wintering Rhizomys of different plant feed nutrient utilization. (1) of wintering the period Rhizomys six species feed apparent digestibility of dry matter significance test, the test results up to a very significant level, indicating differences the wintering period Rhizomys apparent dry matter digestibility of different plant feed highly significant. Which the wintering period Rhizomys pups on Pennisetum, Miscanthus apparent digestibility of dry matter is higher, digestion and utilization of the pups these two plants feed dry matter better. Wintering Rhizomys in mice and rats, Pennisetum, the bamboo dry matter apparent digestibility, wintering midterm mice and rats better utilization of these two plants feed dry matter digestion. (2) on the wintering period Rhizomys six kinds of plant feed crude protein apparent digestibility significant test, the test results up to a very significant level, show that the wintering Rhizomys different plant feed crude protein apparent digestibility differences highly significant. Which the wintering period Rhizomys pups Pennisetum, Miscanthus apparent digestibility of crude protein, the pups better utilization of these two plant feed crude protein digestion. Wintering Rhizomys in mice and rats bamboo, Pennisetum apparent digestibility of crude protein in mice and rats better utilization of these two plant feed crude protein digestion. (3) wintering Rhizomys, six species feed apparent digestibility of acid detergent fiber significance test, the test results up to a very significant level, indicating that the acidic the wintering period Rhizomys different plant feed apparent digestibility of detergent fiber a significant difference. Which the wintering period Rhizomys pups Pennisetum, Miscanthus apparent digestibility of acid detergent fiber, the pups better utilization of these two plant feed acid detergent fiber digestion. Wintering Rhizomys in mice and rats, higher apparent digestibility of acid detergent fiber bamboo Pennisetum wintering midterm mice and rats better utilization of these two plant feed acid detergent fiber digestion. 5. Plant feed grade index GI quality evaluation of six species feed, sort and significant test of the six species feed GI value, the results: the GI value of the the wintering the period Rhizomys pups, 6 species feed the difference was not significant, six species feed on bamboo rat pups growth of the difference was not significant wintering the midterm mice and rats, the GI value of the six species feed very significant difference, indicating that six species feed on mice the wintering period Rhizomys in Growth and rats a significant difference at this stage to choose the right plants feed on Rhizomys grows extremely important. The growth stages the wintering period Rhizomys GI value of the six species feed Miscanthus and bamboo is relatively high, indicating a higher quality of Miscanthus and bamboo, more favorable to the growth of the various growth stages Rhizomys.
