摘要

本试验旨在研究锰对1~4周龄五龙鹅生长性能、屠宰性能、胫骨发育和酶活性的影响，以确定鹅饲粮中锰的适宜添加水平。试验选用1日龄体重相近的五龙鹅360只，随机分为6个组，每组6个重复，每个重复10只（公母各占1/2）。各组分别在基础饲粮（锰含量为20 mg/kg）中添加0（Ⅰ组）、30（Ⅱ组）、60（Ⅲ组）、90（Ⅳ组）、120（Ⅴ组）、150 mg/kg（Ⅵ组）的锰。试验期为4周。结果表明：1）采用不相关比较法进行分析，饲粮锰添加水平为117.74 mg/kg时平均日增重最大，饲粮锰添加水平为105.71 mg/kg时料重比最低。2）Ⅴ组屠宰率、半净膛率、全净膛率和腿肌率显著或极显著高于Ⅰ组（P<0.05或P<0.01），腹脂率极显著低于Ⅰ组（P<0.01）。3）Ⅳ、Ⅴ组骨密度、骨强度及粗灰分、钙含量显著或极显著高于Ⅰ组（P<0.05或P<0.01）。4）Ⅳ、Ⅴ组血清含锰超氧化物歧化酶（MnSOD）活性显著或极显著高于Ⅰ组（P<0.05或P<0.01），肝脏苹果酸脱氢酶（MDH）和脂蛋白脂酶（LPL）活性显著或极显著低于Ⅰ组（P<0.05或P<0.01）。由此可见，适宜饲粮锰添加水平能够提高1~4周龄五龙鹅的生长性能、屠宰性能和胫骨发育，建议鹅饲粮中锰添加水平为105.71~117.74 mg/kg。

Abstract

This experiment was conducted to study the effects of manganese on growth performance, slaughter performance, tibia development and enzyme activities of Wulong geese aged from 1 to 4 weeks, and to find the appropriate supplemental level of manganese. A total of 360 one-day-old Wulong geese with similar average body weight were randomly divided into 6 groups with 6 replicates per group and 10 geese per replicate (half male and half female). Geese in the groups were fed the basal diet (manganese content was 20 mg/kg) supplemented with 0 (group Ⅰ), 30 (group Ⅱ), 60 (group Ⅲ), 90 (group Ⅳ), 120 (group Ⅴ) and 150 mg/kg (group Ⅵ) manganese, respectively. The experiment lasted for 4 weeks. The results showed as follows: 1) using unrelated comparative analysis method, when the dietary manganese level was 117.74 mg/kg, the average daily gain reached the highest, and when the dietary manganese level was 105.71 mg/kg, the ratio of feed to gain reached the lowest. 2) The dressed percentage, percentage of half-eviscerated yield, percentage of eviscerated yield and percentage of leg muscle in groups Ⅳ and Ⅴ were significantly higher than those in group Ⅰ (P<0.05 or P<0.01), and the percentage of abdominal fat in group Ⅴ was significantly lower than that in group Ⅰ (P<0.05). 3) The bone mineral density, bone strength, ash and calcium contents in groups Ⅳ and Ⅴ were significantly higher than those in group Ⅰ (P<0.05 or P<0.01). 4) The serum manganese superoxide dismutase activity in groups Ⅳ and Ⅴ was significantly higher than that in group Ⅰ (P<0.05 or P<0.01), and the activities of malic dehydrogenase and lipoproteinesterase in liver in groups Ⅳ and Ⅴ were significantly lower than those in group Ⅰ (P<0.05 or P<0.01). In conclusion, dietary manganese at appropriate supplemental level can promote growth performance, slaughter performance and tibia development of Wulong geese aged from 1 to 4 weeks, and the optimal supplemental level of manganese is 105.71 to 117.74 mg/kg.
