The objective of this study was to evaluate the effects of giant cactus harvest time and the inclusion of pigeon pea hay in improving the ensiling process and the nutritional composition of cactus silage. In total, 40 polyvinyl chloride-PVC mini-silos (10 × 40 cm) were used. Mini-silos were distributed in a 2 × 5 factorial scheme, referent to 2 harvest times (18 and 24 months) and 5 levels (0, 10%, 20%, 30%, and 40%) of pigeon pea hay inclusion in a randomized design. Effluent losses (p < 0.001) showed a negative linear effect as the inclusion of pigeon pea hay increased. Gas losses (p < 0.001), dry matter (DM) recovery (p < 0.001), and pH (p < 0.001) revealed the interactive effects between the pigeon pea hay inclusion and the harvest time. The DM content was higher in the giant cactus harvested at 24 months. The difference in nutritional composition promoted by the harvest time did not affect the silage quality. The gradual inclusion of pigeon pea hay improved the fermentative and bromatological characteristics of giant cactus silage. It is important to highlight that the inclusion of pigeon pea hay contributed to the increase in pH without affecting the necessary acidity for ideal conservation. |
