摘要

本试验旨在研究不同饲粮非纤维性碳水化合物（NFC）/中性洗涤纤维（NDF）对黔北麻羊瘤胃发酵参数、血浆生化指标和养分消化率的影响。采用3×3拉丁方试验设计，选取6只健康成年黔北麻羊为试验动物，将其分为3组，每组2个重复，每个重复1只羊。试验Ⅰ组、试验Ⅱ组、试验Ⅲ组饲粮NFC/NDF分别为2.14：1.00、1.05：1.00、0.40：1.00（实测值）。试验分3期，每期15 d，包括10 d预试期和5 d正试期。检测指标包括：饲粮养分消化率、瘤胃发酵参数（pH、缓冲力、氨态氮和挥发性脂肪酸浓度、纤维素酶活性）、血浆生化指标（脂多糖、白蛋白、尿素氮、葡萄糖含量及过氧化氢酶、谷草转氨酶、超氧化物歧化酶、谷胱甘肽过氧化物酶活性）。结果显示：1）3个试验组干物质采食量差异不显著（P>0.05），试验Ⅲ组各养分消化率均显著低于试验Ⅰ组、试验Ⅱ组（P<0.05）。2）试验Ⅰ组瘤胃液pH显著低于试验Ⅱ组、试验Ⅲ组（P<0.05）；试验Ⅲ组瘤胃液缓冲力显著高于试验Ⅰ组（P<0.05），纤维二糖酶活性、乙酸浓度显著低于试验Ⅰ组（P<0.05），总挥发性脂肪酸、丁酸浓度显著低于另外2组（P<0.05）；试验Ⅰ组、试验Ⅱ组、试验Ⅲ组瘤胃液乙酸/丙酸依次升高、丙酸浓度依次下降，各组间差异显著（P<0.05）；3组间瘤胃液羧甲基纤维素酶、木聚糖酶、微晶纤维素酶活性差异不显著（P>0.05）。3）试验Ⅰ组、试验Ⅱ组、试验Ⅲ组血浆脂多糖含量依次显著下降（P<0.05），其余血浆生化指标差异不显著（P>0.05）。综合来看，过高NFC/NDF对黔北麻羊瘤胃发酵参数和血浆生化指标有不良影响，本试验条件下，饲粮NFC/NDF以1.05：1.00为宜。

Abstract

The present study was conducted to investigate the effects of non-fiber carbohydrate to neutral detergent fiber ratio (NFC/NDF) on rumen fermentation parameters, plasma biochemical indexes and nutrient digestibility of Qianbeima goats. Six healthy adult Qianbeima goats were selected and allocated to 3 groups with 2 replicates per group and 1 goat per replicate using 3×3 Latin square design. Trial group Ⅰ, trial group Ⅱ, and trial group Ⅲ were fed diet with varying NFC/NDF at 2.14:1.00, 1.05:1.00 and 0.40:1.00 (measured values), respectively. The trial lasted for 45 d consisted of 3 periods with 10 d of pre-trial period and 5 d trial period each. The detecting indexes were as follows: dietary nutrient digestibility, rumen fermentation parameters (pH, buffer capacity, ammonia nitrogen and volatile fatty acid concentrations, and cellulose activity) and plasma biochemical indexes [the contents of lipopolysaccharide, albumin and urea nitrogen glucose, and the activities of hydrogen peroxidase, glutamic-oxal(o)acetic transaminase and superoxide dismutase and glutathione peroxidase]. The results showed as follows: 1) there was no significant difference for dry matter intake among 3 groups (P>0.05); trial group Ⅲ showed significantly lower nutrient digestibility compared with trial group Ⅰ and trial group Ⅱ (P<0.05). 2) Trial group Ⅰ resulted in significantly decreased rumen fluid pH over trial group Ⅱ and trial group Ⅲ (P<0.05); trial group Ⅲ significantly increased rumen buffer capacity compared with trial group Ⅰ (P<0.05), but significantly decreased cellobiase activity and acetic acid concentration compared with trial group Ⅰ(P<0.05), and also significantly decreased total volatile fatty acids and butyrate concentrations compared with the other two groups (P<0.05); trial group Ⅰ, trial group Ⅱ and and trial group Ⅲ resulted in gradually increased acetate to propionate ratio and gradually decreased propionate concentration, and the differences among groups were significant (P<0.05); the activities of carboxymethyl cellulose, xylanase and microcrystalline cellulose in rumen fluid were not significantly affected (P>0.05). 3) Plasma lipopolysaccharide content was gradually significantly decreased in trial group Ⅰ, trial group Ⅱ and trial group Ⅲ (P<0.05), while there were no significant differences for other plasma biochemical indexes (P>0.05). It is indicated from the results that over-high NFC/NDF is not beneficial to rumen fermentation parameters and plasma biochemical index of Qianbeima goats, and 1.05: 1.00 is the appropriate level under the conditions of the present study.
