| 摘要: |
| 为了探讨不同饲粮粗纤维（CF）水平对生长鹅饲料中各种纤维素和钙（Ca）、磷（P）消化率的影响,选取3月龄健康鹅48只，随机分为8组，每组6只，各试验组日粮中分别添加61.5，101.0，136.0，170.5，198.0，225.0，243.0和286.0 g/kg苜蓿粉（CF依次为46.9，51.5，60.7，77.6，81.1，95.9，109.2和124.1 g/kg），调整各组日粮至代谢能（ME）、粗蛋白（CP）、钙（Ca）、有效磷（AP）、蛋氨酸（Met）、赖氨酸（Lys）等水平基本一致。结果表明，在ME和CP等水平基本一致的条件下，苜蓿粉添加量在61.5～286.0 g/kg(CF为46.9～124.1 g/kg)时，CF的消化率为17.15%～25.35%，中性洗涤纤维(NDF) 21.04%～30.71%，酸性洗涤纤维(ADF) 19.10%～28.08%，半纤维素(HC)37.53%～72.67%；P表观消化率略有上升，但组间差异不显著(P>0.05)；Ca表观消化率从苜蓿粉添加量为101.0 g/kg时显著下降(P<0.05)。 |

| Abstract: |
| The trivial were conducted to determine the effects of dietary CF levels on the utilizations of fiber,Calcium and Phosphorusin growing Goose.Forty-eight healthy 3-month-old geese were divided into 8 groups (6 in each group).and were fed with diets which contained different alfalfa green hay powder proportions of 61.5,101.0,136.0,170.5,198.0,225.0,243.0 and 286.0 g/kg respectively(the CF were 46.9,51.5,60.7,77.6,81.1,95.9,109.2 and 124.1 g/kg in turn).The results indicated that:on the basis of the same CP,Ca,AP,Met,Lys,ME level,CF digestibility changed in the range of 17.15%-25.35%,NDF in 21.04%-30.71%,ADF in 19.10%-28.08% and HC in 37.53%-72.67%;There was no significant difference in the P apparent digestibility between the eight groups (P>0.05);the apparent digestibility of Ca in different groups detracted with the increasing level of alfalfa meal. |
