“…Regarding the ash, the highest value that was observed with the addition of urea is attributed to the formation of organic salts during ensiling. According to Ryley et al [29], the partial binding of ammonia produced from the degradation of urea with organic acids occurs for the formation of organic salts during anaerobic fermentation in the melon biomass.…”

The objective of this study was to evaluate the silage produced with different mixtures of melon biomass with urea used as an additive. It adopted a completely randomized design in a 5 × 2 factorial scheme with five replications. The first factor was made up of five mixtures on an as-fed basis (AF) of the melon, including plant (branch and leaf) and fruit (culled melon, after harvest), where the amount of fruit varied as follows: 0% fruit, 5% fruit, 10% fruit, 20% fruit, and 100% fruit. The second factor was represented by the use of urea in the silage as follows: 0% and 1.5% urea AF. The highest silage dry matter (DM) content (200 g/kg DM) was observed in the silage with 20% fruit. Regarding the crude protein, the highest content (69.8 g/kg DM) was found in the silage with the addition of urea. The highest loss through the gas (GAS) was observed in the silages with 0% and 100% fruit (0.6 and 1.13%), with no addition of urea. The silages made with melon biomass and the addition of 20% and 100% fruit showed differences regarding the fermentative pattern, chemical composition, and aerobic stability, thus being the most indicated mixtures for silage making.

“…The increase in mineral matter concentration observed in corn grain silages moistened by cactus pear mucilage with urea may have occurred due to the formation of organic salts during ensiling, most of the buffering power of plants can be attributed to anions such as salts of organic acids, orthophosphates, sulfates, nitrates (Catchpool and Henzell, 1971), due to the high mineral content in the cactus pear (Table 1) and urea. Ryley (1969) referred to the partial binding of ammonia produced from the degradation of urea with organic acids to form organic salts during the anaerobic fermentation of the ensiled material. This increase in mineral content was also observed by Macêdo et al (2008).…”

The purpose of this study was to evaluate the effects of different proportions of cactus pear mucilage as a moistening additive on chemical composition, ammonia nitrogen, volatile fatty acids, microbial dynamics, fermentation losses, pH, and aerobic stability of corn grains in the form of silage throughout storage periods. The study was carried out in a completely randomized design with a factorial arrangement (5×2), with four replications. The factors corresponded to five forms of moistening for corn grain silage, 0, 5, 10, 20, and 40% of cactus pear mucilage (MA) associated or not with urea (U) in the level of 1.5% of DM. The lowest DM content was found in the silage moistened with 40% of cactus pear mucilage, and the greatest CP content was found in the same treatment but when urea was added. Lower contents of propionic and butyric acids were observed in the silages moistened with 5 and 10% of cactus pear without and with the addition of urea. Dry matter recovery was higher in the treatments with water and 10% of cactus pear. The use of urea affected the LAB population only at 15 d of silo opening, providing a bigger population (6.58 logs CFU g-1) when compared to silages without urea (6.27 logs CFU g-1). The lower concentrations of propionic and butyric acids observed in the silage moistened with 5 and 10% of cactus pear mucilage, regardless of the addition of urea. However, it is recommended to use 10% of cactus pear mucilage without the addition of urea, as it provides better indicators of good-quality silage.
