摘要

为了在短时间内满足动物的饲料需求,畜牧与植物生产一体化是一条很有前途的路线。因此,本研究的目的是评估与聚乙二醇相关的合欢豆荚对香蕉叶灰烬提取物处理过的稻草体外消化率的影响,并与山羊瘤胃液孵育。该研究于2018年3月至6月在动物生产与营养研究单位(URPRONAN)和昌大学土壤科学实验室进行。稻秆和香蕉叶分别在三州和昌农业发展研究所收获;而金合欢豆荚则是在距离乍得恩贾梅纳25公里的Koundoul地区收集的。在试验开始时,经过灰分提取液的制备、稻草处理和配制口粮后,取样品测定其化学成分并评价其体外消化率。结果表明:经灰分浸膏处理后,钠(801 ~ 900 mg/kg)、磷(1537.45 mg/kg)、钙(2440 ~ 11520 mg/kg)、镁(1243 ~ 1410 mg/kg)、钾(5951.75 ~ 10276.75 mg/kg)含量均有所增加。相反,有机质含量(从90.13 dm降至81.86%DM)、脂质含量(从1.39 dm降至0.39 dm)和NDF含量(从96.44 dm降至77.57 dm)下降。而灰分含量(9.96 ~ 18.13%DM)则与之相反。带合欢豆荚的水稻秸秆补体与聚乙二醇显著相关或不相关(p < 0.05)。相反,干物质的体外消化率和微生物质量(MM)略有下降。除残氮外,处理秸秆体外消化率的其他参数均高于未处理秸秆。聚乙二醇对香蕉叶灰提取物处理水稻秸秆体外消化率的影响,提高了山羊消化率参数。

Effect of Acacia albida Pods Associated to Polyethylene Glycol on the In vitro Digestibility of Rice Straw Treated with Banana Leaves Ashes Extract in Goat
In order to satisfy the feed requirements of animals in short periods, the integration of livestock to plant production appears as a promising route. Thus, the aim of this work was to evaluate the effect of Acacia albida pods associated to polyethylene glycol on the in vitro digestibility of rice straw treated with extract of ashes of banana leaves, incubated with ruminal fluid from a goat. The study was carried out from March to June 2018 in the Research Unit of Animal Production and Nutrition (URPRONAN) and in the Laboratory of Soil Sciences of the University of Dschang. The rice straw and the banana leaves were harvested in the Agricultural Research Institute for Development (IRAD) of Santchou and Dschang respectively; whereas the Acacia albida pods were collected in the Region of Koundoul, locality situated at 25km from Ndjamena in Tchad. At the beginning of the experiment, after the preparation of the ash extract, treatment of rice straw and formulation of the rations, samples were taken in order to determine the chemical composition and evaluate the in vitro digestibility. The results showed that the treatment with ash extract led to an increase in sodium (801 to 900 mg/kg), phosphorus (1537.45 mg/kg), calcium (2440 to 11520 mg/kg), magnesium (1243 to 1410 mg/kg) and potassium (5951.75 to 10276.75 mg/kg) content. Contrarily, it induces a decrease in the content of organic matter (from 90.13 to 81.86%DM), lipids (from 1.39 to 0.39) and NDF (from 96.44 to 77.57). However, the reverse effect was observed with contents in ash (from 9.96 to 18.13%DM). The complementation of rice straw with Acacia albida pods associated or not to polyethylene glycol significantly (p 0.05). The in vitro digestibility of dry matter and the microbial mass (MM) instead observed a slight decrease. Apart from the residual nitrogen, the highest values of the other parameters of in vitro digestibility were obtained with treated rice straw compared to untreated rice straw. Acacia albida pods associated to polyethylene glycol on the in vitro digestibility of rice straw treated with banana leaves ashes extract improves digestibility’s parameters in goat.
