ABSTRACT An experiment was conducted to evaluate the effect of a polyherbal mixture based on Withania somnifera, Ocimum tenuiflorum, Tinospora cordifolia and Emblica officinalis, on lamb’s growth and blood metabolites. Thirty-two lambs (initial body weight BW 25 ± 4.1 kg) were randomly assigned to the treatments which consisted of the polyherbal ImmuPlus at dietary concentrations of 0, 0.1, 0.2 and 0.3% of dry matter (DM) for 60 days. There was a quadratic response to polyherbal in average daily gain (p < 0.01) and feed conversion (p < 0.05). The optimal concentration estimated by regression for maximum ADG was 0.14 ± 0.08% DM of ImmuPlus. Ruminal DM digestibility was not affected but pH was reduced linearly (p < 0.05). Ruminal N-NH3 (p < 0.01) and total VFA concentration showed a quadratic increment (p < 0.05) whereas butyrate proportion was increased linearly (p < 0.05). There was no effect in most blood metabolites related to energy metabolism, but uric acid was linearly reduced (p < 0.01) and bilirubin showed a quadratic decrement (p < 0.05). Mean corpuscular haemoglobin (p < 0.01) increased linearly (p < 0.10), lymphocytes and segmented neutrophils showed a quadratic response (p < 0.01) and platelets showed a linear reduction (linear p < 0.05). The inclusion of ImmuPlus improved the daily gain in finishing lambs and feed efficiency at 0.1% DM without altering blood chemistry and blood biometry.

羔羊多草饲料添加剂:对生产性能、血液生化和生物测定的影响

摘要 进行了一项实验,以评估基于睡茄、罗勒、心叶和余甘的多草混合物对羔羊生长和血液代谢物的影响。32 只羔羊(初始体重 BW 25 ± 4.1 kg)被随机分配到由多草药 ImmuPlus 组成的处理组,日粮浓度为 0、0.1、0.2 和 0.3% 的干物质 (DM),持续 60 天。在平均日增重 (p < 0.01) 和饲料转化率 (p < 0.05) 方面,对复合草药的反应呈二次方反应。通过回归估计的最大 ADG 的最佳浓度是 ImmuPlus 的 0.14 ± 0.08% DM。瘤胃 DM 消化率不受影响,但 pH 值线性降低(p < 0.05)。瘤胃 N-NH3 (p < 0.01) 和总 VFA 浓度呈二次增加 (p < 0. 05) 而丁酸盐比例呈线性增加 (p < 0.05)。大多数与能量代谢相关的血液代谢产物没有影响,但尿酸呈线性降低(p < 0.01),胆红素呈二次递减(p < 0.05)。平均红细胞血红蛋白 (p < 0.01) 呈线性增加 (p < 0.10),淋巴细胞和分段中性粒细胞呈二次反应 (p < 0.01),血小板呈线性减少 (线性 p < 0.05)。在 0.1% DM 条件下,添加 ImmuPlus 可提高育肥羔羊的日增重和饲料效率,而不会改变血液化学和血液生物测定。平均红细胞血红蛋白 (p < 0.01) 呈线性增加 (p < 0.10),淋巴细胞和分段中性粒细胞呈二次反应 (p < 0.01),血小板呈线性减少 (线性 p < 0.05)。在 0.1% DM 条件下,添加 ImmuPlus 可提高育肥羔羊的日增重和饲料效率,而不会改变血液化学和血液生物测定。平均红细胞血红蛋白 (p < 0.01) 呈线性增加 (p < 0.10),淋巴细胞和分段中性粒细胞呈二次反应 (p < 0.01),血小板呈线性减少 (线性 p < 0.05)。在 0.1% DM 条件下,添加 ImmuPlus 可提高育肥羔羊的日增重和饲料效率,而不会改变血液化学和血液生物测定。
