Abstract

Preparation of silage is a common method to preserve green forage. It plays an important role in improving forage utilization, solving the problem of forage provision and meeting the nutritional needs of livestock in winter and spring. The effects of various supplements on tetraploid black locust (Robinia pseudoacacia L.) silage were studied by analyzing its color, odor, texture, pH value, the composition and amount of organic acids, the ammonia-N/total-N ratio, crude protein, neutral detergent fibers and acid detergent fibers. Our results show that the silage quality of wilted tetraploid R. pseudoacacia preserved alone is acceptable, while adding brown sugar and Yishengkang to tetraploid R. pseudoacacia foliage improved its quality. The treatments consisting of the tetraploid R. pseudoacacia mixed with 33% and 50% corn stalk achieved the best silage quality in terms of pH value (p < 0.01), amount of lactic acid (p < 0.01), the ammonia-N/total-N ratio (p < 0.01) and the fermentation quality. These treatments also resulted in a high content of crude protein and lower amounts of acid detergent fibers. The treatment consisting of the tetraploid R. pseudoacacia mixed with 20% corn stalk was also good in the quality of its fermentation.
