Our aim was to evaluate a whole-grain diet containing 0 (T1) and 60% (T2) waste papaya silage in vitro, in situ and in vivo. In vitro, biogas, methane and dry matter degradation (DMDiv), neutral detergent fiber (NDFDiv) and crude protein (CPDiv) were determined at 72 h; in situ, DM (DMDis), NDF (NDFis) and CP (CPDis) digestibility was determined at 72 h; in vivo, consumption and apparent digestibility of DM (DMI and DMD) and NDF (NDFI and NDFD), daily weight gain (DWG), rumen characteristics (pH, bacterial and protozoan counts) were determined. In addition, we performed coproparasitoscopic analysis and interviews with producers. Biogas production, methane, DMDiv, CDPiv, DMDis, DMD, NDFD, pH, bacterial and protozoan counts, and parasite load of nematodes and coccidia were not different between treatments (p > 0.05). T2 showed more NDFDiv, CPDis, DMI, NDFI, DWG than T1, while T1 was higher than T2 in NDFDis (p < 0.05). The results obtained from in vitro, in situ and in vivo techniques indicate that the diet with 60% waste papaya silage (T2) showed a similar response to the control diet (T1). Therefore, waste papaya silage is a non-conventional feeding alternative for weaned calves in the Costa Chica region of the state of Guerrero, Mexico.
我们的目的是评估一种含有 0（T1）和 60%（T2）木瓜废料青贮的全谷物饮食，包括体外、体内和原位试验。在体外试验中，于 72 小时测定生物气、甲烷和干物质降解（DMDiv）、中性洗涤剂纤维（NDFDiv）和粗蛋白（CPDiv）；在原位试验中，于 72 小时测定干物质（DMDis）、中性洗涤剂纤维（NDFis）和粗蛋白（CPDis）消化率；在体内试验中，测定干物质（DMI 和 DMD）和中性洗涤剂纤维（NDFI 和 NDFD）的表观消化率、消耗量、日增重（DWG）、瘤胃特征（pH 值、细菌和原生动物计数）。此外，我们进行了粪便寄生虫镜检分析和与生产者的访谈。生物气产生、甲烷、DMDiv、CDPiv、DMDis、DMD、NDFD、pH 值、细菌和原生动物计数以及线虫和球虫的寄生虫负荷在处理之间没有差异（p＞0.05）。T2 的中性洗涤剂纤维分解率、粗蛋白消化率、干物质采食量、中性洗涤剂纤维采食量、日增重均高于 T1，而 T1 的中性洗涤剂纤维消化率高于 T2（p＜0.05）。体外、体内和体内技术获得的结果表明，含有 60%木瓜废料青贮（T2）的饮食对对照饮食（T1）表现出相似的反应。因此，木瓜废料青贮是墨西哥格雷罗州科斯塔奇卡地区断奶小牛的一种非常规饲料替代物。
