The exploitations of non-conventional feeds for livestock have sparked great interest due to human-animal competition for conventional feedstuffs. The majority of animal feedstuffs are formulated with grains as the major ingredient, resulting in tautness and an increase in the costs of conventional feeds. This practice has underscored the necessity for an alternatively cheap and sustainable non-conventional feedstuff to salvage the feeding restraint to animal production. With this, the present study aimed at evaluating the effect of soaked false yam tuber meal (SFYTM) on the haematological indices and serum biochemical profile of weaner rabbits.
Sixteen local weaned rabbits of diversified breeds and sexes were randomly apportioned to dietary treatments containing 0, 10, 15, and 20 % of soaked false yam tuber in replacement for maize in a maize-fishmeal-based diet. Following feeding trials, blood samples from the rabbits were taken and analyzed using haematology and chemistry analyzers.
The haematological assay revealed significant differences (P < 0.05) among treatments for red blood cells (RBCs), total white blood cells (TWBCs), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC) and monocytes. For haemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), platelet, lymphocytes, neutrophils, esoniphiles, and basophils, no significant differences (P > 0.05) were achieved. With the serum biochemical tests, significantly higher values were obtained for alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and sodium relative to the control. Despite some of the evaluated parameters having relatively high values, they tumbled within the normal range of values for a healthy weaned rabbit.
False yam tuber can therefore be exploited as a substitute for maize in rabbits' diets without detrimental effects on the haematological and biochemical markers of the farm animals.
由于人畜对传统饲料的竞争，开发非常规家畜饲料引发了极大兴趣。大多数动物饲料以谷物为主要成分进行配制，导致传统饲料供应紧张且成本增加。这种做法凸显了需要一种廉价且可持续的非常规饲料来缓解对动物生产的饲养限制。据此，本研究旨在评估浸泡过的薯蓣块茎粉（SFYTM）对断奶仔兔血液学指标和血清生化特征的影响。
将16只不同品种和性别的本地断奶仔兔随机分配到以玉米 - 鱼粉为基础的日粮处理组，日粮中分别含有0%、10%、15%和20%的浸泡过的薯蓣块茎以替代玉米。经过饲养试验后，采集兔子的血样并使用血液学和化学分析仪进行分析。
血液学检测显示，处理组之间的红细胞（RBC）、总白细胞（TWBC）、平均红细胞血红蛋白（MCH）、平均红细胞血红蛋白浓度（MCHC）和单核细胞存在显著差异（P < 0.05）。对于血红蛋白（Hb）、血细胞比容（PCV）、平均红细胞体积（MCV）、血小板、淋巴细胞、中性粒细胞、嗜酸性粒细胞和嗜碱性粒细胞，未发现显著差异（P > 0.05）。血清生化检测结果显示，相对于对照组，碱性磷酸酶（ALP）、天冬氨酸转氨酶（AST）、丙氨酸转氨酶（ALT）和钠的值显著更高。尽管一些评估参数的值相对较高，但它们仍在健康断奶仔兔的正常范围内。
因此，薯蓣块茎可作为兔子日粮中玉米的替代品，而不会对家畜的血液学和生化指标产生不利影响。
