The objective of this study was to evaluate the impact of Mombasa or blue panic as a salt-tolerant alternative to alfalfa on growth performance, puberty, blood hematology, serum metabolites, and serum mineral profile in growing goats. Twenty-four growing goats of 4 months old age with 14.45 ± 0.6 kg average body weight were assigned to three treatment diets with 8 animals per treatment. Weights of each animal were measured at the onset of the trial and subsequently on a weekly basis until the end of the trial duration. A pair of blood samples were collected from each goat a jugular vein puncture and were subjected to either hematological or biochemical analysis. The results showed that treatment diets had no significant effects ( > 0.05) on the final body weight and total body weight gain. However, blue panic had significantly increased ( < 0.05) neutral detergent fiber and crude protein digestibility. The diet-influenced MCV was significantly higher ( < 0.05) in the Alfalfa group. The serum concentration of glucose was significantly increased ( < 0.05) in the blue panic-fed group, while the urea was increased in the Mombasa-fed group. Additionally, the serum concentrations of P, Na, and Cl were significantly increased ( < 0.05) in the blue panic-fed group, but Mombasa significantly increased ( < 0.05) the K concentration. In conclusion, the study indicated that blue panic ranked the best among salt-tolerant alternatives to replace alfalfa, resulting in better feed utilization, serum metabolites, and serum minerals with no adverse effects on growth performance and puberty. This study provides new insight into the shift to the cultivation of salt-tolerant plants with a high level of crude protein in arid areas as a potential approach for the sustainability of the livestock industry.
本研究的目的是评估蒙巴萨草或蓝黍草作为苜蓿的耐盐替代品对生长山羊的生长性能、青春期、血液血液学、血清代谢物和血清矿物质谱的影响。将24只4月龄、平均体重14.45±0.6千克的生长山羊分配到三种处理日粮中，每种处理8只动物。在试验开始时测量每只动物的体重，随后每周测量一次，直至试验期结束。通过颈静脉穿刺从每只山羊采集一对血样，进行血液学或生化分析。结果表明，处理日粮对最终体重和总体重增加没有显著影响（P>0.05）。然而，蓝黍草显著提高了（P<0.05）中性洗涤纤维和粗蛋白消化率。苜蓿组受日粮影响的平均红细胞体积显著更高（P<0.05）。蓝黍草饲喂组的血清葡萄糖浓度显著升高（P<0.05），而蒙巴萨草饲喂组的尿素升高。此外，蓝黍草饲喂组的血清磷、钠和氯浓度显著升高（P<0.05），但蒙巴萨草显著提高了（P<0.05）钾浓度。总之，该研究表明，在耐盐替代品中，蓝黍草在替代苜蓿方面表现最佳，能带来更好的饲料利用率、血清代谢物和血清矿物质，且对生长性能和青春期没有不利影响。本研究为干旱地区转向种植粗蛋白含量高的耐盐植物提供了新的见解，这是实现畜牧业可持续发展的一种潜在途径。
