“…However, such high protein silages have a problem with regard to massive protein degradation and amino acids deamination during the ensiling process [6,7]. Our previous study showed that Indigofera and Moringa leaf silages had high pH values and high ammonia concentrations that contributed to their low silage quality [8]. It had been recommended that a certain silage additive is necessary to prevent or to minimize such considerable proteolysis in high protein silages.…”

Aim: The objective of this experiment was to evaluate the effect of the addition of tannin extract to Moringa and Indigofera leaf silages on their chemical composition, silage quality characteristics, and in vitro rumen fermentation parameters and digestibility. Materials and Methods: Moringa and Indigofera leaves were cut (3 cm length) and added with either 0, 2, or 4% chestnut tannin in three replicates. The leaves were then inserted into lab-scale silos (1 L capacity) and kept for 30 days. Silage samples were subjected to silage quality determination, chemical composition analysis, and in vitro rumen fermentation and digestibility evaluation using a gas production technique. Data obtained were subjected to the analysis of variance with a factorial statistical model in which the first factor was different silage species and the second factor was tannin addition levels. Results: Tannin addition at 4% dry matter (DM) increased neutral detergent insoluble crude protein (NDICP) and acid detergent insoluble CP (ADICP) of Indigofera silage. A similar response was observed in Moringa silage, but it required less tannin, i.e., 2% DM to increase its NDICP and ADICP. Moringa silage had lower pH than that of Indigofera silage (p<0.05), and tannin addition did not change pH of both Indigofera and Moringa silages. Higher addition level of tannin decreased total volatile fatty acid (VFA) and ammonia concentrations of both Indigofera and Moringa silages (p<0.05). A higher level of tannin addition reduced ruminal total VFA concentration, ammonia, in vitro DM digestibility, and in vitro organic matter digestibility of Indigofera and Moringa silages (p<0.05). Tannin addition also decreased ruminal methane emission of both Indigofera and Moringa silages (p<0.05). Conclusion: Tannin extract can reduce proteolysis of high protein silage from Moringa and Indigofera leaves.

Ensiling of high-protein forages like alfalfa, indigofera, cassava and moringa, however, are characterized by considerable extent of proteolysis. This study aimed to perform a meta-analysis from various published experiments regarding the effect of protein level on fermentative quality of silage. Papers reported data on protein contents of silages and their fermentative characteristics were collected and integrated in a database. A total of 15 papers and comprised of 155 data points were included. The ensiled materials were peas, wheat, barley, maize, sorghum, alfalfa and mucuna. The ensiling period varied from 20 to 303 days. Data were statistically analyzed by using the mixed model methodology. Studies from different papers were treated as random effects whereas protein level in silage was treated as fixed effect. The model statistics used was p-value. Results revealed that higher protein level led to an increase of DM loss in silage (p<0.01). Protein was negatively correlated with NDF (p<0.001) and ADF (p<0.05). Increasing protein level elevated pH value of the silage (p<0.05) and tended to increase acetate concentration (p<0.1). Ethanol concentration was elevated by increasing silage protein level (p<0.05). Higher silage protein level increased organic matter digestibility (OMD), lactic acid bacteria (LAB) population, nitrate and ammonia concentrations of the silage (p<0.05). It can be concluded that higher protein level induces proteolysis in the silage and reduces its fermentative quality.
