连续两年进行了两个独立的2×2完全随机区组试验,旨在评价贮藏方法(高湿与干燥)和单宁含量(高与低)对用于喂饲肥育中猪(28～96公斤)的粒用高粱营养价值的影响。当籽粒含水量为24～26％时收获高水分的高粱,并在厌氧条件下进行贮藏。贮藏六个月后,在与饲料日粮掺合以前,把高水分籽粒干燥(35℃)到含水量为11～12％。另外,收获含水量在18～20％时的干燥籽粒,干燥(40℃)到11～12％,然后贮于通风罐中。在每个试验中,每圈4头共48头杂种猪。肥育中的或已育肥的猪饲料日粮
Two separate, 2 × 2, complete randomized block trials were conducted for two consecutive years to evaluate the effect of storage methods (high humidity and dryness) and tannin content (high and low) on pigs fed finishing diets (28 to 96 Kg) of grain with the nutritional value of sorghum. Sorghum is harvested when the grain moisture content is 24-26%, and stored under anaerobic conditions. After six months of storage, the high moisture kernels were dried (35 ° C) to a moisture content of 11-12% prior to being blended with the dietary diets. In addition, dry kernels harvested at 18-20% moisture were harvested, dried (40 ° C) to 11-12%, and stored in a vented jar. In each of the four experiments, 48 crossbred pigs were used per round. Finished or fattened pig feed ration
