Abstract

The study assessed percentage preference and proximate composition of some selected plant species in Idemili South Area of Anambra State. Plants were identified and collected for herbarium preparation. A total of 23 different species belonging to 16 families were identified. These consisted of 11 trees, 4 shrubs, 3 herbs and 3 grasses. These plants were harvested, processed and stored separately. A 25 gm portion of each plant was measured and administered to 3 matured goats per day. The feeding trial lasted for 23 days. The frequency and rate of consumption of each plant was determined using a stop watch. The results showed that Manihot esculenta representing 73.3 % was highly preferred plant by all the animals while Colocasia esculenta having 18.7 % was moderately preferred. Proximate composition of the fodder was determined using standard method and results revealed that protein content ranged from 5.85% in Tridax procumbens and 23.86% in Desmodium scorpiurus. Lipid content ranged between 1.31 % and 8.37 % for Carica papaya and Manihot esculenta respectively while crude fibre content ranged from 8.09 to 33.01% in Tridax procumbens and Pennisetum purpureum respectively. The highest ash content (11.28 %) was recorded in Colocasia esculenta while the least level (2.17 %) in Tridax procumbens. Also, moisture content was observed to be highest in Manihot esculenta (10.29 %) and least in Dialium guineensis, while carbohydrate contents ranged between 13.41 % and 67.82 % for Persea americana and Tridax procumbens respectively. It could be concluded that plant species under this study were found to be rich in essential nutrients but Vernonia amygdalina, Amaranthus spinosus, Manihot esculenta, Ficus elasticoides and Milicia excelsa were most preferred plant species by experimental animals.

阿南布拉州Idemili南部用作牲畜饲料的一些植物种类的偏好百分比/近似组成

研究评估了阿南布拉州Idemili南部地区一些选定植物物种的百分比偏好和近似组成。对植物进行鉴定和收集，用于标本室的制作。共鉴定出16科23种。其中乔木11株，灌木4株，草本3株，禾本科3株。这些植物分别收获、加工和储存。每株植物取25克，每天喂给3只成年山羊。试验期23 d。每个植物的消耗频率和速度是用秒表来确定的。结果表明，马尼欧特是所有动物的高度偏好植物，占73.3%，而土芋草为中等偏好植物，占18.7%。采用标准方法测定饲料的近似组成，结果表明，原藜的蛋白质含量为5.85%，天蝎棘的蛋白质含量为23.86%。番木瓜和马尼洪的脂肪含量分别为1.31% ~ 8.37%，赤竹和狼尾草的粗纤维含量分别为8.09 ~ 33.01%。灰分含量最高的是土芋(Colocasia esculenta)，为11.28%，最低的是三叉戟(tritriax procumbens)，为2.17%。水分含量最高的是马尼奥特(10.29%)，最低的是几内亚羊草(Dialium guineensis)，而碳水化合物含量分别在13.41% ~ 67.82%之间。由此可见，本研究的植物种类富含必需营养素，但实验动物最喜欢的植物种类是苦杏仁、苋菜、马尼乌特、弹性榕树和米莉莎。关键词:植物种类，山羊，家畜饲料，近似组成，爱德米利南部地区
