Abstract：
The objective was to characterize the pastures by grazing cycle, as well as to evaluate the performance of buffaloes in intensive rotational grazing in a silvopastoral system in the eastern Amazon supplemented with agro-industry co-products in order to characterize the grazing cycles, the composition of the fractions, and the carcass yield. Fifteen non-castrated, crossbred water buffaloes (Murrah × Mediterranean) were used. All animals used in the study were clinically healthy and weighed approximately 458 kg. The animals were grazed in a single group, and supplementation (1% of live weight-LW/day) was divided into three treatments: control (control-conventional ingredients); Cocos nucifera coconut cake (Cocos nucifera) (coconut cake-70%); and palm kernel cake (Guinean elaeis) (palm kernel cake-70% palm kernel cake). The chemical composition of the forage is different in each part of the plant, with higher protein values in the leaves (11.40%) and higher acid detergent fiber (ADF) values in the stems (50.03%). Among the ingredients of the supplement, corn has the highest percentage of indigestible protein (35.57%), most of the protein in palm kernel cake is B3 (49.11%), and in Coco, B2 (51.52%). Mombasa grass has a higher percentage of B3 and B2 proteins; the indigestible fraction is lower in the leaves (17.16%). The leaf/stem ratio also varied between grazing cycles, being better in the second cycle (2.11%) and with an overall average of 1.71. Supplement consumption varied between cycles and was higher in the control treatment, with an overall mean of 4.74. There was no difference in daily weight gain and carcass yield, with an average of 1 kg/day and 49.23%, respectively. Therefore, it can be concluded that including supplements based on by-products from the coconut and palm oil agro-industries promotes performance and carcass yields compatible with conventional supplements. Their use reduces production costs, optimizes the utilization of forage mass, enhances the sustainability of the production chain, and, therefore, is recommended.
摘要：
目的是通过放牧周期来表征牧场，以及评估在东部亚马逊地区的silvopastoral系统中，水牛在密集轮牧中的表现，并补充了农用工业联合产品，以表征放牧周期，馏分的组成，和car体产量。15个非cast割，使用了杂交水牛（Murrah×地中海）。研究中使用的所有动物都是临床健康的并且体重约458kg。这些动物在一组中放牧，和补充（活重的1％-LW/天）分为三种处理：对照（对照常规成分）；Cocosnucifera椰子蛋糕（Cocosnucifera）（椰子蛋糕-70％）；和棕榈仁饼（几内亚elaeis）（棕榈仁饼-70％棕榈仁饼）。草料的化学成分在植物的每个部分都不同，叶片中蛋白质值较高（11.40％），茎中酸性洗涤纤维（ADF）值较高（50.03％）。在补充剂的成分中，玉米的难消化蛋白质含量最高(35.57%)，棕榈仁饼中的大部分蛋白质是B3(49.11%)，在可可,B2(51.52%)。蒙巴萨草的B3和B2蛋白百分比较高；叶片中的不可消化部分较低（17.16％）。放牧周期之间的叶/茎比也有所不同，在第二个周期更好（2.11%），总体平均值为1.71。补充消耗量在周期之间变化，在对照治疗中更高，总体平均值为4.74。日增重和car体产量没有差异，平均每天1公斤，占49.23%，分别。因此,可以得出结论，包括基于椰子油和棕榈油农产品工业的副产品的补充剂可以促进与常规补充剂兼容的性能和car体产量。它们的使用降低了生产成本，优化饲料质量的利用，增强生产链的可持续性，and,因此,是推荐的。
