“…However, this did not occur, so the lowest BC was found in silage with the highest proportion of gliricidia hay (40%). The reduction in BC could be related to the composition of cactus pear, which has high content of minerals such as calcium (22.15 g/kg DM), potassium (45.65 g/kg DM), and magnesium (6.89 g/kg DM) [ 17 ], which have buffering activity, neutralizing the organic acids formed by fermentation and preventing a drop in pH [ 15 ]. Furthermore, the reduction in silage moisture caused by the inclusion of hay in the ensiled mass may also have contributed to the reduction in the buffering capacity of the silage, which is beneficial because, according to Muck [ 18 ], the higher the buffering capacity, the greater the amount of lactic acid that will have to be formed so that the pH reaches levels sufficient to inhibit the activity of clostridial microorganisms and enterobacteria, which harm the silage quality.…”

“…Due to the higher P content in gliricidia (3.2–4.9 g/kg) [ 35 ] compared to cactus pear (1.24–1.54 g/kg [ 17 ]), this nutrient was expected to be increased with increasing levels of inclusion of gliricidia hay in the silage composition, compared to the control silage (0% hay). However, despite the increase in P levels, the silages would not meet the needs of beef cattle (1.6 g/kg) [ 34 ], which would require dietary supplementation.…”

“…No research has evaluated the Boron content in legume–cactus silages combined with gliricidia, just as there are no recommendations for the Boron content in the composition of diets to meet the nutritional requirements of beef cattle [ 38 ]. According to Araújo et al [ 17 ], the increase in B content is important because this micronutrient brings benefits to the immune system, with a direct action on the thyroid and Ca metabolism, and has effects on reproductive activity in males.…”

Cactus pear is used in large proportions in diets for small ruminants in semiarid regions. However, its exclusive use is not recommended due to the low fiber and crude protein content and the high water and mineral content, leading to metabolic disorders, low dry matter intake, and weight loss. The use of mixed cactus silage associated with protein and fibrous sources seeks to overcome the deficits in dry matter, fiber and crude protein, aiming to improve the nutritional quality of the diets that will be offered to ruminants. Thus, the use of gliricidia hay in cactus pear silages could represent an important alternative to improve the nutritional and fermentative characteristics of the ensiled material. Therefore, our aim was to evaluate the fermentation dynamics, nutritional characteristics, and aerobic stability of mixed silages of cactus pear combined with different levels of gliricidia hay. This was a completely randomized experimental design with five treatments and five repetitions. The treatments consisted of different levels of inclusion of gliricidia hay (0, 10, 20, 30, and 40% on a dry matter basis) in the composition of mixed cactus pear silages. The inclusion of gliricidia hay in the composition of mixed silages of cactus pear resulted in a quadratic effect for dry matter recovery, pH, NH3-N, buffering capacity, aerobic stability, ether extract, P, K, Na, and Zn (p < 0.05). There was a reduction in density, effluent losses, maximum pH, mineral matter, non-fiber carbohydrates, Ca, Mg, Fe, and Mn (p < 0.05), and an increase in the time to reach maximum pH as well as an upward trend in pH, dry matter, organic matter, crude protein, neutral detergent fiber, acid detergent fiber, and B (p < 0.05). Under experimental conditions, the inclusion of gliricidia hay between 20 and 30% in cactus pear-based silage provided an improvement to the chemical composition and fermentation parameters of the silages.

“…It is also possible that the protein derived from pornuncia hay be complexed to the fibrous fraction and thus has a lower rate of degradability, making it less available to synchronize with saccharides from the diet. According to Araújo et al (2023), the inclusion of cactus in approximately 10% associated with pornunça hay may have provided asynchrony in the degradation of protein and carbohydrates, due to the difference in the ruminal degradation kinetics that may not have provided the most efficient use of the diet by the ruminal microbiota.…”

The aim of this study was to assess the impact of diets containing pornunça hay (Manihot sp) and levels of cactus pear (Opuntia ficus-indica L. Mill) in their natural state on the intake, digestibility, ingestive behavior, milk production, and quality, as well as the economic feasibility for lactating goats. Eight multiparous goats with 30 days of lactation and an average weight of 40 ± 2.5 kg and an average production of 2 ± 1.8 kg/day were used, distributed in a double Latin square design (4x4). The treatments consisted of isoproteic diets which are composed of increasing levels of cactus pear (0, 10, 20, and 30% dry matter). Incorporating cactus pear into the diet of lactating goats resulted in a significant decrease (P<0.05) in water intake and the intake of most evaluated nutrients, which directly reflected in the diet effectively consumed by the animals. However, it did not affect (P>0.05) milk production or fat-corrected milk production. Incorporating cactus pear into the diet of lactating goats resulted in a significant decrease (P<0.05) in production costs, water intake, and the intake of most evaluated nutrients, which were directly reflected in the diet effectively consumed by the animals. However, it did not affect (P>0.05) milk production or fat-corrected milk production. The level of 30% cactus pear inclusion in the diet of lactating goats increased the economic efficiency of production without affecting milk production and maintaining a good composition of solids.

The aim was to evaluate the effect of the cactus pear levels (0, 15, 30, and 45%) in cassava shoot silages on the fermentation profile, chemical composition, and aerobic stability. Four treatments were tested with five repetitions, totaling 20 silos. The inclusion of cactus pear in cassava shoots silages promoted an increase in gas losses (P < 0.001), buffering capacity (P < 0.001), pH (P = 0.033), mineral matter (P < 0.001), total carbohydrates (P < 0.001), non-fiber carbohydrates (P < 0.001) and a decreasing in dry matter (P < 0.001), organic matter (P < 0.001), ether extract (P = 0.002), and crude protein (P < 0.001) content. A quadratic effect was observed for effluent losses (P < 0.001), with greater effluent losses (94.78 kg/t natural matter) obtained with the inclusion of 30% cactus pear in cassava shoots silages. Cactus pear inclusion in cassava shoots silage promoted a reduction in the pH during oxygen exposure (P = 0.008). Including cactus pear in up to 45% of cassava silage, shoots cause changes in the fermentation and nutritional characteristics. However, values found in the silages are by good quality standards.
