Description
The production of good quality hay in Central Brazil has been limited by the nature of cultivated species and constant presence of rainfalls. However, at the end of summer and part of fall seasons the environmental conditions are adequate for hay making but the forages show lower nutritive value. An alternative to improve the quality of tropical grasses hay would be the use of ammonia. Several studies (Buettner et al., 1982; Grotheer et al., 1986; Brown et al., 1987; Moore and Lechtenberg, 1987), showed decreases in NDF and hemicellulose on forages treated with ammonia. The influence of levels of ammonia on quality of hay (Grotheer et al., 1986; Brown et al., 1987); time of exposure (Moore et al., 1985; Grotheer et al., 1986) ; effects of periods of storage (Woolford and Tetlow, 1984) has been explored. The objective of this study was to determine the effects of different levels of anhydrous ammonia, time of exposure and periods of storage on quality of two tropical grasses hay (Melinis minutiflora and Brachiaria decumbens).
