The current study was conducted to optimize the growth performance of Indian goat breed (Barbari), with a focus on enhancing productivity for intensive commercial goat farming systems. The study explored the impact of varying concentrations of concentrate feed mix on the growth, nutrient utilization, rumen fermentation, and blood health of intensively raised young Barbari goats. Thirty-two male weaned kids, approximately 5 months old and weighing 9.43 ± 0.24 kg on average, were individually housed and divided into four equal groups. All kids received ad libitum Bengal gram straw and green fodder as basal rations, supplemented with barley grain at 0.7% of body weight in the control group (T), and concentrate mix at 0.7%, 1.4%, and 2.1% of body weight in groups T, T and T, respectively. Significantly faster weight gain was observed in finisher kids receiving higher concentrations of concentrate feed mix (P < 0.001). DM intake (g/kg W) increased (P < 0.05) in T compared to T. CP intake (g/kg W) was higher in T, and T than in T, and T. Elevated levels of TCA-precipitable nitrogen, total VFA production, and a favorable shift in the acetate/propionate ratio were observed in kids under T compared to T. Total digestible nutrients (TDN) percentage in the feed was enhanced in T (P < 0.01), and digestible crude protein (DCP) percentage was greater in T, and T compared to T (P < 0.05). Finisher goats under T retained higher (P < 0.05) amount of nitrogen/kg W compared to T and T. Furthermore, red blood cell counts (RBC) increased in T, and T compared to T (P < 0.05), while white blood cell counts (WBC) were enhanced in concentrate mixture added treatments (T, T and T) compared to T (P < 0.05). Haemoglobin concentration was significantly higher in T, and T compared to T, and T (P < 0.05). Blood glucose levels were elevated in groups receiving concentrate mix (T, T, T) compared to T; and the albumin to globulin (A/G) ratio tended to decrease due to increased globulin levels in blood plasma (P < 0.05). In conclusion, Barbari finisher goats raised with 2.1% of their body weight as concentrate mix supplementation under an intensive feeding system experienced improved growth, nutrient utilization and blood profile. Barbari goats, known for their high reproductive efficiency and adaptability to semi-arid climates, are ideal for meat production. Their farming offers great potential for small-scale farmers and entrepreneurs, especially when utilizing abundantly available pulse straw-based diets supplemented with such concentrate level.
本研究旨在优化印度山羊品种（巴尔巴里山羊）的生长性能，重点是提高集约化商业山羊养殖系统的生产力。该研究探讨了不同浓度的精饲料混合料对集约化饲养的幼年巴尔巴里山羊的生长、养分利用、瘤胃发酵和血液健康的影响。32只雄性断奶羔羊，平均年龄约5个月，平均体重9.43±0.24千克，单独饲养并分为四组。所有羔羊自由采食孟加拉鹰嘴豆秸秆和青饲料作为基础日粮，对照组（T组）补充占体重0.7%的大麦粒，T1、T2和T3组分别补充占体重0.7%、1.4%和2.1%的精饲料混合料。在接受较高浓度精饲料混合料的育肥羔羊中观察到显著更快的体重增加（P<0.001）。与T组相比，T3组的干物质摄入量（克/千克体重）增加（P<0.05）。T2组和T3组的粗蛋白摄入量（克/千克体重）高于T组和T1组。与T组相比，T3组羔羊的三氯乙酸沉淀氮水平、总挥发性脂肪酸产量升高，乙酸/丙酸比值发生有利变化。T3组饲料中的总可消化养分（TDN）百分比提高（P<0.01），T2组和T3组的可消化粗蛋白（DCP）百分比高于T组（P<0.05）。与T组和T1组相比，T3组育肥山羊每千克体重保留的氮量更高（P<0.05）。此外，与T组相比，T2组和T3组的红细胞计数（RBC）增加（P<0.05），而与T组相比，添加精饲料混合料的处理组（T1、T2和T3组）的白细胞计数（WBC）增加（P<0.05）。与T组和T1组相比，T2组和T3组的血红蛋白浓度显著更高（P<0.05）。与T组相比，接受精饲料混合料的组（T1、T2、T3组）血糖水平升高；由于血浆球蛋白水平升高，白蛋白与球蛋白（A/G）比值趋于降低（P<0.05）。总之，在集约化饲养系统下，以体重2.1%的精饲料混合料进行补充饲养的巴尔巴里育肥山羊，其生长、养分利用和血液状况得到改善。巴尔巴里山羊以其高繁殖效率和对半干旱气候的适应性而闻名，是肉类生产的理想选择。它们的养殖为小规模农民和企业家提供了巨大潜力，特别是当利用大量可得的基于豆类秸秆的日粮并补充这种精饲料水平时。
