This study aimed to evaluate the effects of hydroponic fodder on the growth and reproductive performance of Black Bengal goats in East Champaran, Bihar, during the years 2020-21 and 2021-22. A total of 24 goats were randomly assigned to four groups: Control (C) with extensive grazing, gram straw, concentrate feed, and green fodder; Treatment 1 (T1) receiving C + 300 g/day of wheat hydroponic fodder; Treatment 2 (T2) with 300 g/day of maize hydroponic fodder alone; and Treatment 3 (T3) receiving C + a combination of 150 g/day of wheat and 150 g/day of maize hydroponic fodder. Each group comprised 6 animals. The nutrient composition analysis revealed that wheat hydroponic fodder had significantly higher (P < 0.05) levels of dry matter, crude protein, and lignin, whereas maize contained higher nitrogen-free extract, crude fiber, ether extract, and ash. In terms of growth performance, T3 showed the highest body weight gain and daily weight gain, outperforming T2, T1, and the control group (P < 0.05). Though differences between T2 and T3 were not significant (P > 0.05) across both years, T3 consistently exhibited better performance. Reproductive performance indicators, such as age at puberty, age of first kidding, and kid mortality rates, were significantly lower (P < 0.05) in T3, T1, and the control group compared to T2. However, there were no significant differences (P > 0.05) between T2 and T3 in these parameters. T3 also showed the highest kidding size and birth weight of kids (P < 0.05), followed by T2, T1, and the control group. The cost of feed per kilogram of body weight gain was lowest in T3, followed by T2, T1, and the control. In conclusion, the combination of maize and wheat hydroponic fodder (T3) resulted in better growth and reproductive performance compared to feeding maize or wheat hydroponic fodder alone. Furthermore, this feeding strategy reduced the cost per kilogram of live weight gain, indicating its potential for enhancing the sustainability and profitability of goat farming systems in the region.
本研究旨在评估水培饲料对东查普拉班,比哈尔邦黑孟加拉山羊在 2020-21 年和 2021-22 年期间的生长和繁殖性能的影响。共有 24 只山羊被随机分为四组:对照组(C)进行广泛放牧、豆秸、浓缩饲料和绿色饲料;处理 1(T1)每天接受 300 克小麦水培饲料;处理 2(T2)每天单独接受 300 克玉米水培饲料;处理 3(T3)每天接受 C+150 克/天的小麦和 150 克/天的玉米水培饲料。每组由 6 只动物组成。营养成分分析表明,小麦水培饲料的干物质、粗蛋白和木质素含量显著更高(P<0.05),而玉米的氮非提取物、粗纤维、乙醚提取物和灰分含量更高。在生长性能方面,T3 组的体重增加和日增重最高,优于 T2、T1 和对照组(P<0.05)。尽管 T2 和 T3 组在两年间的差异不显著(P>0.05),但 T3 组的表现始终更好。繁殖性能指标,如初情期年龄、首次产仔年龄和仔畜死亡率,T3、T1 和对照组均显著低于 T2(P<0.05)。然而,T2 和 T3 组在这些参数上没有显著差异(P>0.05)。T3 组的产仔数和仔畜出生体重也最高(P<0.05),其次是 T2、T1 和对照组。每公斤体重增重的饲料成本最低的是 T3,其次是 T2、T1 和对照组。总之,与单独喂养玉米或小麦水培饲料相比,玉米和小麦水培饲料(T3)的组合喂养可提高生长和繁殖性能。此外,这种喂养策略降低了每公斤活体重增重的成本,表明其有可能提高该地区山羊养殖系统的可持续性和盈利能力。
