“…Addition of 8% and 10% pistachio PB also increased (P < 0.05) CP contents of silages. This can be explained with the formation of tannin-protein complexes, which can cause a reduction in the rate of microbial degradation of proteins (Santos et al 2000), and relatively higher CP content of pistachio PBs than corn silage material. Pistachio PB increased (P < 0.05) ADF values of silages depending on the increment level in the present study.…”

“…Tannins in silos, in an environment close to a neutral pH, form complex compounds with soluble protein silage, thereby preventing the degradation of proteins by microorganisms and the subsequent reduction of the ammonia nitrogen concentration. This process prevents protein losses and improves silage quality (Barry & Manley 1986;Santos et al 2000).…”

The objective of this study was to determine the effect of adding different levels of pistachio by-product (PB) on the fermentation quality, nutritive value and in vitro methane (CH 4 ) production of corn silage. For this purpose, silages were prepared in the 1.5 l glass jars by adding with 2%, 4%, 6%, 8% and 10% pistachio PB (as a dry matter basis). The results showed that addition of 6%, 8% and 10% pistachio PB levels decreased (P < 0.05) silage acetic acid content. Increment of pistachio PB level increased (P < 0.05) silage propionic acid content, but it decreased (P < 0.05) ammonia nitrogen values. Addition of all levels of pistachio PB decreased (P < 0.05) gas production (from 251.70 to 196.76 ml/g dry matter (DM)), in vitro organic matter digestibility (from 70.26% to 61.62%) and metabolizable energy (from 9.69% to 8.27 MJ/kg DM) values. Similarly, increment-level pistachio PB decreased (P < 0.05) of in vitro methane production level. As a result, pistachio PB might have a potential usage value as silage additive when undesired ruminal methane production is aimed to be suppressed by ruminant. ARTICLE HISTORY

“…Spraying TA on alfalfa before ensiling affected neither N concentration nor effective degradability of crude protein (CP) but reduced the percentage of CP solubilised at initiation of incubation (Santos et al, 2000). However, soya bean treatment with TA reduced ruminal degradation and intestinal digestibility of proteins (Hervas et al, 2000).…”

Alfalfa protein is poorly utilised by ruminants due to its rapid degradation in rumen. The objective of the study was to assess the influence of spraying tannic acid (TA) on chopped alfalfa hay on in vitro rumen fermentation and nitrogen (N) retention by sheep. Alfalfa hay with and without TA was fed to sheep to determine nutrient digestibility and N balance. TA was sprayed on chopped alfalfa at three concentrations to determine its effect on in vitro fermentation of dry matter (DM) and N balance in sheep. Final TA concentrations were 0, 30, 60 and 90 g TA per kg DM. The control was sprayed with the same amount of water but without TA. In vitro DM degradation and the production of gas, ammonium-N (NH 4 -N) and short-chain fatty acid (SCFA) were measured. TA-sprayed alfalfa and the control were fed to sheep to determine nutrient digestibility and N retention. Addition of TA had no influence on the extent and rate of gas production but significantly decreased NH 4 -N concentration at 30 (P , 0.05), 60 and 90 (P , 0.0001) g/kg DM. Addition of polyethylene glycol (PEG) to TA-sprayed alfalfa increased NH 4 -N to a level comparable to non-TA-sprayed alfalfa. Spraying of alfalfa with TA significantly decreased (P , 0.05) isovalerate but did not affect the total and individual SCFA acid production. Tannic acid significantly (P , 0.05) reduced in vitro true degradability of DM (IVTD) after 24 h incubation at levels of 60 and 90 g TA per kg DM. Neutral-detergent fibre digestibility (dNDF) after 24 h (P , 0.01), 60 and 90 (P , 0.0001) g TA per kg DM. The effect of TA on either IVTD or dNDF was not significant (P . 0.05) after 48 h of incubation. There was a strong linear relationship between percentage increase in gas production due to PEG and protein precipitation capacity (R 2 5 0.94). N digestibility was significantly reduced with all three levels of TA additions. However, the proportion of urine-N to total N output was reduced by adding 60 g (P , 0.05) and 90 g (P , 0.01) TA per kg DM. Serum metabolites and liver enzymes were not affected by TA (P . 0.05). Higher faecal N as the TA level increased indicates incomplete dissociation of tannin-protein complexes post ruminally. Factors affecting dissociation of tannin-protein complexes need further study.

“…formaldehyde and tannic acid have been tested to improve the ensiling properties of alfalfa silage, but reports of their efficacy are inconsistent 2 . Previous studies suggested that the inoculation with lactic acid bacteria (LAB) at ensiling could improve the fermentation of legume silage by accelerating the production of lactic acid (LA) to cause occurrence of acidic conditions rapidly 3 .…”

SummaryThis study was carried out to examine the possible effect of fresh and frozen pre-fermented juice (PFJ) on the fermentation quality, nutritive value and in vitro gas production parameters of alfalfa (Medicago sativa L.) silage. Barley (B), wheat (W) and grass herbage (G) were used to prepare the PFJs. Both fresh (PFJ-B, PFJ-W and PFJ-G) and frozen (PFJ-B F , PFJ-W F and PFJ-G F ) PFJs were investigated. Frozen PFJs were prepared by freezing fresh PFJs at -22 o C with 20% glycerol (v/v). Treatments of alfalfa silage consist of (1) control (untreated alfalfa silage); (2) silage treated with PFJ-B; (3) silage treated with PFJ-W; (4) silage treated with PFJ-G; (5) silage treated with PFJ-B F ; (6) silage treated with PFJ-W F and (7) silage treated with PFJ-G F . Each treatment had five replicate glass jars and replicates were ensiled in 1.0 L jars. Silages treated with fresh and frozen PFJs, regardless of plant material, had better fermentation quality than the control silage in terms of lower pH, butyric acid (BA) and ammonia nitrogen (NH 3 -N) concentrations. Additionally, treated silages with fresh PFJs had higher lactic acid (LA) concentration (P<0.05) and in vitro organic matter digestibility (IVOMD), metabolizable energy (ME) content and gas production values (P<0.05) than control silage. According to results of this study, PFJ treatments increased the nutritive value, fermentation quality, IVOMD, ME content and gas production values of alfalfa silage.
