Abstract：
The study aimed to assess the impact of feeding Bengal gram residual forage-based pelleted Total Mixed Ration (TMR) with varying concentrate (C) to roughage (R) ratios on feed intake, nutrient utilization, growth, and carcass characteristics in Barbari kids. Sixteen weaned male Barbari kids (av. age, 233 ± 11 days; weight, 13.86 ± 0.76 kg) were divided into two groups (T1 and T2), each receiving different pelleted diets (TMR) with distinct concentrate to roughage ratios (T1 with 60:40; T2 with 40:60). The kids were fed for 133 days, and a digestion trial was conducted at the end of the study. After completion, all kids were slaughtered. Although, kids under T1 consumed higher (P < 0.001) amount of dry matter, and crude protein compared to T2, which was due to a higher concentrate to roughage ratio in T1. But, the average daily body weight gain (ADG) of finisher kids was 88.53, and 79.83 g/d/kid in T1 and T2, respectively; however, the difference was non-significant. Digestibility of organic matter, crude protein, and total carbohydrate was also greater in T1 compared to T2. Total digestible nutrients intake was higher (P < 0.001) in T1; similarly intake of digestible energy, and metabolizable energy were significantly increased (P < 0.01) in T1 compared to T2. Concentrations of volatile fatty acids and NH3-nitrogen were also enhanced (P < 0.05) in T1 compared to T2. We observed similar carcass weight, and dressing percentage in both groups, and carcass composition remained unaffected. The pelleted diet containing greater ratio of concentrate: roughage (60:40) had no additional benefits in terms of ADG, and carcass traits in finisher kids. Therefore, it may be concluded that the Bengal gram residual forage-based pelleted TMR diet containing C40: R60 (TDN 57.13%, DCP 7.64%, ME 9.11MJ/kg feed) is suitable for optimizing growth performance with desirable carcass traits, and meat composition in finisher Barbari kids reared under the intensive system.
摘要：
该研究旨在评估饲喂孟加拉克剩余饲料的颗粒总混合日粮（TMR）与不同的浓缩物（C）与粗饲料（R）比率对采食量的影响，养分利用率，增长,和Barbari孩子的car体特征。16个断奶的男性Barbari孩子（av。年龄,233±11天；体重，13.86±0.76kg）分为两组（T1和T2），每个人都接受不同的颗粒化饮食（TMR），具有不同的浓缩物与粗饲料比（T1为60：40；T2为40：60）。孩子们被喂养了133天，在研究结束时进行消化试验。完成后,所有的孩子都被屠杀了。虽然,T1以下儿童消耗较高(P<0.001)的干物质，和粗蛋白与T2相比，这是由于T1中浓缩物与粗饲料的比率更高。但是,在T1和T2中，完成者孩子的平均每日体重增加（ADG）分别为88.53和79.83g/d/kid；但是，差异无显著性。有机物的消化率，粗蛋白，与T2相比，T1中的总碳水化合物也更大。T1的可消化营养素总摄入量较高（P<0.001）；类似地，与T2相比，T1和代谢能显着增加（P<0.01）。与T2相比,T1中的挥发性脂肪酸和NH3-氮的浓度也增加(P<0.05)。我们观察到类似的屠体重量，两组的穿衣率，和car体组成不受影响。就ADG而言，含有更大比例的浓缩物：粗饲料（60：40）的颗粒饮食没有额外的益处，和完成孩子的car体特征。因此,可以得出结论，孟加拉克残余饲料为基础的颗粒状TMR饮食含有C40：R60（TDN57.13％，DCP7.64%，ME9.11MJ/kg饲料）适用于优化具有理想的car体性状的生长性能，和精加工器Barbari孩子在密集系统下饲养的肉成分。
