摘要

具有抗营养潜力的毒素和物质阻碍了块根作物与动物饲料的成功结合。然而,农场动物生理状态的最终指标是生长性能和血液特征。因此,本研究采用单配方和混合配方的薯蓣根粕和虎精根粕来评价鸡的生产性能和血液学反应。240只Bisaya鸡被喂食玉米和根茎饲料。每组处理60只鸡,3个重复,每重复20只鸡。试验饲粮为:T1(100%玉米基)、T2(50%毛蚶饲粮)、T3(50%毛蚶饲粮)和T4(25%毛蚶+25%毛蚶饲粮)。每两周采集采食量、体重和平均增重(MWG),收获时进行胴体评价。检测血液学指标和血清谱。T1和T4饲粮产生的体重和MWG最显著,T2和T3次之。与T2和T3相比,T1和T4的饲料系数(FCR)显著提高。T4特定生长率(SGR)与T1和T2相似,但大于T3。T1饲粮的屠宰重、屠宰重、胴体成分和可食用内脏最显著,T4饲粮次之。T4饮食比T2和T3饮食更能提高PCV、RBC、Hb、胆固醇和甘油三酯,但T4和T1之间没有显著差异。所有单独的根粕替代品(T2和T3)均对鸡的生产性能产生负面影响;然而,与以玉米为基础的饲粮(T1)相比,25%赤纹弓形虫+25%赤纹弓形虫混合物(T4)提高了生长缓慢的鸡的生长性能、大部分胴体特征和血液特征。

Hematology, Blood Serum, Growth Performance, and Carcass Characteristics of Slow-growing Chickens Fed Single and Blended Root Meals
Toxins and substances with anti-nutritional potential have impeded the successful integration of root and tuber crops into animal diets. However, the ultimate indices of the physiological state of a farm animal are the growth performance and blood profiles. Hence, single and mixed formulations of Dioscorea hispida and Cyrtosperma merkusii root meals were used to assess chicken performance and hematological reactions. Two hundred and forty Bisaya chickens were fed with maize and root meals. Each set of treatments had 60 chickens, with three replicates of 20. The diets were: T1 (100% corn-based), T2 (50% D. hispida diet), T3 (50% C. merkusii diet), and T4 (25% D. hispida+25% C. merkusii diet). Feed intake, body weight, and mean weight gain (MWG) were collected biweekly, and carcass evaluation was done on harvesting. Hematological indices and serum profiles were tested. The T1 and T4 diets produced the most significant body weight and MWG, followed by T2 and T3. An improved feed conversion ratio (FCR) for T1 and T4 were significantly different from T2 and T3. The T4 specific growth rate (SGR) was similar to T1 and T2 but greater than T3. The T1 diet gave the most significant slaughter weight and dress weight, carcass components, and edible offal, followed by T4. The T4 diet raised PCV, RBC, Hb, cholesterol, and triglycerides more than T2, and T3, but no significant difference was found between T4 and T1. All solo root meal substitutes (T2 and T3) negatively impacted chicken performance; however, the 25% D. hispida+25% C. merkusii mix (T4) enhanced growth performance, most carcass features, and the blood profiles of slow-growing chickens when compared to a corn-based diet (T1).
