FUNAAB alpha biomet

The FUNAAB-Alpha chicken, a dual-purpose genotype developed by the Federal University of Agriculture, Abeokuta (FUNAAB), represents an improved local breed with enhanced adaptability and productivity under tropical conditions. Despite its relative heat tolerance compared to exotic breeds, the FUNAAB-Alpha chicken remains susceptible to acute thermal challenges that may disrupt its physiological balance and limit its productive efficiency. The chickens of three strains (normal feather, frizzle feather and naked neck) were offered citrus peel powder in water at the rate of 0, 3, 6 and 9g per litre drinking water before being subjected to acute heat challenge. The null hypothesis (H0) is that citrus peel powder at varied dosage does not change the body temperature and haematological responses in FUNAAB alpha chickens during acute heat challenge while H1 means citrus peel powder at varied dosage does change the responses.

FUNAAB-Alpha鸡是由阿贝奥库塔农业联邦大学（Federal University of Agriculture, Abeokuta，缩写FUNAAB）研发的双用途品系，属于经改良的地方品种，在热带环境下具备更优异的适应性与生产性能。尽管相较于外来品种，该品系已具备一定的耐热性，但仍易受急性热应激侵扰，进而扰乱其生理平衡并限制生产效率。本研究选取三种羽毛类型的FUNAAB-Alpha鸡（正常羽、卷羽与裸颈），在对其施加急性热应激前，分别在饮水中添加0、3、6、9克每升的柑橘皮粉。本研究的原假设（H₀）为：急性热应激期间，不同剂量的柑橘皮粉不会改变FUNAAB-Alpha鸡的体温及血液学响应；备择假设（H₁）则为：不同剂量的柑橘皮粉会对上述响应产生显著影响。
