“…Although the two seaweeds differed in their N content, the proportion of ADIN was lower than 4 g/100 g of total N in both of them. The ADIN was considered an indicator of N availability by some ruminant feeding systems, although the validity of the analytical method has been recently questioned [34]. The low ADIN proportion in P. umbilicalis is consistent with the low indigestible proportion of CP reported previously for this seaweed [20], indicating that it can supply a high amount of digestible protein to the small intestine in ruminants [20].…”

The study analyzed the characteristics, chemical composition, and in vitro gas production kinetics of Porphyra umbilicalis and Saccharina latissima silages. Each seaweed was ensiled in vacuum bags (three bags/silage) following a 2 × 3 factorial design, with two pre-treatments (unwilted or pre-wilted) and three silage types: unwashed seaweed ensiled without additive; seaweed washed and ensiled without additive; and seaweed washed and ensiled with 4 g of formic acid (FAC) per kg seaweed. Silages were kept for 3 months in darkness at 20 °C. Pre-wilting prevented (p < 0.001) effluent formation and reduced (p ≤ 0.038) the production of NH3-N and volatile fatty acids for both seaweeds. Both pre-wilting and washing increased (p < 0.05) the ruminal degradability of P. umbilicalis silages but not of S. latissima silages. The pH of the FAC-treated silages was below 4.0, but ranged from 4.54 to 6.23 in non FAC-treated silages. DL-lactate concentrations were low (≤23.0 g/kg dry matter) and acetate was the predominant fermentation product, indicating a non-lactic fermentation. The estimated ruminal degradability of the P. umbilicalis and S. latissima silages was as average, 59.9 and 86.1% of that for high-quality rye-grass silages, respectively, indicating a medium-low nutritional value of these seaweed silages for ruminants.

“…In addition, higher ADIN values can be inherent to forage cultivated in a tropical climate with high temperatures, as reported by Johnson, Reiling, Mislevy, and Hall (2001) and Adesogan (2010). Also, it has recently been shown that the ADIN content is overestimated due to contamination with nitrogen from cetyl trimethylammonium bromide used in the ADF analysis (Marcos, Carro, García, & González, 2018).…”

Forage availability depends on seasonality, and this may cause problems for farmers maintaining regular livestock productivity throughout the year. Therefore, forage conservation as silage has become an important and popular method of feed storing because it can minimize the loss of nutrients after harvest during storage (Fulgueira, Amigot, Gaggiotti, Romero, & Basílico, 2007). Sorghum [Sorghum bicolor (L.) Moench] is a tropical plant that efficiently uses water and it is a good alternative to maize crops for feeding ruminants, mainly in regions with low or irregular rainfall (Getachew, Putnam, Ben, & Peters, 2016). Compared with maize plants, sorghum plants require less fertilization and less pest control and may grow in soils with a low pH (AERC, 2007). Several authors have reported good ensilability of sorghum

“…Although NDF is the most widely-used consumption predictor, feed with a high ADF also has potential for consumption depression due to the filling effect (Poczynek et al, 2020). Thus, the higher the lignin content, the greater the filling effect (Poczynek et al, 2020) and the lower the digestibility of the diet (Marcos et al, 2018), both accentuated by cellulose content (Table 2).…”

The objective of this study was to evaluate the nutritional changes in silages of four sorghum hybrids at different storage times. The design was a completely randomized in a 4 × 9 arrangement of plots with four replications. The four sorghum hybrids, Qualysilo, Chopper, Dominator, and Maxisilo, were allocated to the plots. In the subplots, sampling times were considered in fresh material and after 1, 3, 7, 14, 28, 56, 112, and 224 days of storage. The material was ensiled in experimental polyvinyl chloride silos and subsequently evaluated for chemical composition and fermentative profile over the nine different periods of the fermentation process. Crude protein was reduced by 1.21g/kg per day until the third day of fermentation. The levels of neutral detergent insoluble nitrogen and acid detergent insoluble nitrogen exceeded the upper limit of 311 g/kg of N. Of the studied silages, an NDF content of 734 g/kg was obtained in Maxisilo, which was higher than the other silages (average: 547 g/kg). Silage production can be achieved with the four materials; however, the Maxisilo sorghum provides silages of lower quality, with a DM content of less than 30%. The other materials fit into the nutritional profiles proposed by the literature, characterizing them as good quality silages.
