“…The response from the use of maniçoba hay in relation to Tifton 85 hay as a source of roughage for the intake variable was expected and is probably related to the high nutritional value of the forage, with adequate CP content and high digestibility of non-fibrous carbohydrate (Maciel et al, 2019). According to França et al (2010), the maniçoba presents anatomical characteristics similar to those of C3 plants, so that its anatomy favors the intake and, consequently, the digestibility, due to the arrangement of the mesophyll with more intercellular spaces than in C4 plants, as well as more spaces between the vascular bundles, which may have conferred to the maniçoba hay greater ruminal degradation when compared to Tifton 85 hay.…”

The objective of this study was to evaluate the metabolic response of native lambs fed Tifton 85 hay (Cynodon dactylon) or Maniçoba hay (Manihot pseudoglaziovii) associated with spineless cactus (Nopalea cochenillifera Salm Dyck). Sixteen Morada Nova lambs were used, with a mean initial weight of 19.36±1.48kg, distributed in a randomized block design, with two treatments and eight replications. Dry matter intake was higher for lambs fed Maniçoba hay compared to Tifton hay, while the body weight at slaughter was not influenced by diets. Regarding the blood metabolites, only the serum concentration of urea was influenced, with higher value observed in the lambs that fed the diet containing Tifton hay. When analyzing blood biomarkers, in the different biweekly collections, a linear increase in the blood concentration of urea, glucose, fructosamine, alkaline phosphatase and sodium was observed, as well as a quadratic effect for serum potassium. The other blood metabolites were not influenced in function of the collection days. The replacement of Tifton 85 hay for Maniçoba hay does not cause negative changes in the dynamics of different biomarkers and presents itself as a promising forage resource.

“…Thus, maniçoba ( Manihot pseudoglaziovii ) represents a complementary alternative to the nutritional deficit present in cactus pear, due to its high nutritional value, contributing to significant increases in the contents of DM, NDF and crude protein (CP). It is a native species adapted to semiarid conditions and, therefore, easy to obtain, which ensures the feeding of the herd during the most critical time of the year (Gouveia et al ., 2015; Maciel et al ., 2019).…”

Fermentation profile and nutritional quality of silages composed of cactus pear and maniçoba for goat feeding

This study aimed to evaluate the fermentation profile and nutritional quality of silages composed of cactus pear and maniçoba. Two experiments were performed: the first evaluated the fermentation characteristics, chemical composition and determined the organic acids in cactus pear silages with the inclusion of five levels of maniçoba (0, 25, 50, 75 and 100%) in six opening times (1, 7, 15, 30, 60 and 90 days). The second experiment determined the nutrient intake, digestibility, water balance and nitrogen balance in Canindé goats fed diets based on cactus pear silage with the inclusion of four levels of maniçoba (25, 50, 75 and 100%), with six animals per treatment. The increase in maniçoba levels in cactus pear silage provided a linear increase in the butyric acid, dry matter (DM), ether extract, crude protein, neutral detergent fibre, acid detergent fibre, lignin, cellulose, hemicellulose, water intake via drinking fountain and metabolic water, and reduced the pH, lactic acid, acetic acid, mineral matter, total carbohydrates, non-fibrous carbohydrates, water intake via food, total water intake, water excreted in the faeces, water excreted in the urine, total water excretion and water balance. Quadratic behaviour was observed for N-NH3, DM recovery and propionic acid, with an increase in maniçoba levels in cactus pear silages. Regarding the different opening times, there was a significant effect in pH, N-NH3, acetic acid, lactic acid and butyric acid (P < 0.050). The inclusion of maniçoba in cactus pear silage improved the fermentation characteristics and nutritional quality to be used in diets for goats.

“…Maniçoba hay is richer in ADF (462.7 g kg -1 vs 386.2 g kg -1 ), NFC (124 g kg -1 vs 25 g kg -1 ) and EE (18.7 g kg -1 vs 11.3 g kg -1 ) than Tifton hay; therefore, the fractions of ADF, NFC and EE in the experimental diets increased with increasing levels of maniçoba hay. Maciel et al (2019) also observed a higher intake of NFC and EE in sheep fed with maniçoba hay than those fed Tifton hay 85.…”

The objective of this study was to evaluate the effect of replacing Tifton 85 hay with maniçoba hay in diets based on spineless cactus on the nutrient intake and digestibility, ingestive behaviour and ruminal parameters of confined sheep. In order to do this, eight male sheep with ruminal cannulae were used, distributed across four levels (0, 333, 666 and 1.000 g kg-1 of dry matter) of replacement of Tifton 85 hay with maniçoba hay in a double Latin square experimental design. The animals were confined for 60 days divided into four periods of 15 days. The replacement of Tifton 85 hay with maniçoba hay did not influence the dry matter intake or digestibility. However, it influenced in a positive linear fashion the intake of non-fibrous carbohydrates and in a linear negative fashion the digestibility of insoluble fibre in neutral detergent and crude protein. The ruminal ammonia-nitrogen and the crude protein ruminal content decreased linearly with the replacement of Tifton 85 hay with maniçoba hay. There was no effect of hay replacement on the production of volatile fatty acids or the microbial biofilm. The total replacement Tifton 85 by maniçoba hay in spineless cactus diets for sheep did not influence total digestible nutrient intake, volatile fatty acid production or biofilm, but did affect crude protein digestibility, ammonia-nitrogen and crude protein content in the rumen. Therefore, maniçoba hay can replace 300 g kg-1 grass hay in spineless cactus diets for sheep without compromising intake and ruminal parameters.
