“…Animal Sciences, v. 43, e52129, 2021& Krause, 2001. The negative correlation between tannins content and the GP volume found in our study agree with the findings of Khazaal, Boza, and Ørskov (1994) and with Chaji, Direkvandi, and Salem (2020) who found that the presence of tannin reduced GP due to the disruption effect on rumen microorganisms.…”

. This study was performed to investigate the effect of replacing alfalfa hay by L. leucocephala leaves in proportions of 25, 50 and 100% on in vitro gas production (GP) parameter, digestibility and in situ degradability in buffalo. Results showed that the volume of GP at 2 to 12 hours after incubation was significantly affected by replacing alfalfa hay with L. leucocephala leaves. In vitro digestibility of organic matter (OMD) differed significantly between treatment as it declined by increasing the alfalfa hay substitution rate from 25 to 100%. The microbial crude protein (MCP) differed significantly between treatments and was the greatest of 589 and 599 mg g-1 of dry matter (DM) when L. leucocephala leaves replaced alfalfa hay at 25 and 50%. The in vitro digestibility of DM (IVDMD) increased significantly at 50% L. leucocephala replacement rate. Moreover, substituting alfalfa hay by L. leucocephala had a significant effect on the in situ degradability parameters. The insoluble but potentially degradable fraction (B) and potential of degradability (A+B) significantly increased for treatment contain 50% L. leucocephala leaves. The effective degradability (ED) was significantly different between dietary treatments and was the greatest when alfalfa hay was replaced by 25 and 50% L. leucocephala. In conclusion, L. leucocephala leaves can substitute 25 to 50% of dietary alfalfa hay in buffalo rations without effect on rumen efficiency.

Aim This study was performed to investigate the effects of Lactobacillus plantarum (LP) on the in vitro gas production (GP) kinetics and ruminal fermentation parameter of three species of tropical forage Ziziphus mauritiana, Acacia victoriae and Moringa oleifera. Methods and Results Treatments were (i) Z. mauritiana (Z) without LP (−ZLP), (ii) Z. mauritiana (Z) with LP (+ZLP), (iii) A. victoriae (A) without LP (−ALP), (4) A. victoriae (A) with LP (+ALP), (5) M. oleifera (M) without LP (−MLP) and (6) M. oleifera (M) with LP (+MLP). The LP was used at 0·5 Mcfarland (1·5 × 108 colony‐forming unit per millilitre (CFU per ml)). Kinetic of GP (GP from the fermentable fraction [b], GP rate [c] and lag phase [L]) and GP were affected (P < 0·05) by plant species and LP. The highest value of b, c and GP were observed in +MLP treatment compared with other treatments. The lowest value of L was observed for the +ZLP treatment compared with other treatments. The GP and fermentation parameter included organic matter digestibility (OMD), metabolizable energy (ME) content, microbial CP (MCP) and truly degraded substrate (TDS) were affected by plant species and LP supplementation. The highest OMD, ME, TDS and MCP values were observed in +MLP treatment. At different incubation times, the highest amount of ammonia‐N was observed in treatment +MLP compared with other treatments. Under the influence of experimental treatments (effect of plant species and LP), the highest concentrations of total volatile fatty acids, acetate and acetate to propionate ratio were observed in treatments +MLP, +ALP and +ALP, respectively. Concentrations of propionate, iso‐butyrate, n‐valerate and iso‐valerate were affected by plant species, and the highest levels were observed in −ZLP, +MLP, −MLP and +MLP tretments, respectively. Conclusions The use of LP as a microbial additive had a positive effect on the in vitro digestibility and ruminal fermentation of tannins‐rich tropical plants. Results suggest that dietary LP inclusion could be an option to improve ruminant energy utilization efficiency of tannins‐rich tropical plants. Significance and Impact of the Study Regardless the effect of the forage species, the use of LP as a microbial additive improved GP and kinetics and also increased OMD, TDS, MCP and enhanced the total in vitro ruminal VFAs production.

“…A higher index in yellowness (b*) can be partly related to the storage of more fat within the muscle. Green tea has dense tannins (Cimmino et al, 2018), so it decreased the blood iron concentrations; therefore, the colour of the meat of the tea-fed cows was lighter than that of the control animals. In vitro studies show a possible effect of dense tannins on the brightness index of meat can reduce microbial bioproduction of vitamin B 12 , a precursor to pigment production (Priolo & Vasta, 2007).…”

BackgroundThe use of plants and by‐products, which are containing a high amount of secondary and anti‐nutritional compounds such as tannins, in animal feed is limited. The methods that can reduce these compounds make facilitate their use in animal feed.ObjectivesThe aim of this study was to reduce the adverse effects of pomegranate peel (PP) tannin for fattening lambs using the tannase‐producing bacteria.MethodsTwenty‐one Arabi male lambs (averagely 35 ± 3.8 kg weight and 8 ± 1.0 months age) were used in a completely randomized design with three treatments and seven replications in the present experiment. The experimental treatments included 1 – control diet (CNT, no PP), 2 – diet containing untreated PP (raw PP, UTPP) and 3 – diet containing PP treated with tannase‐producing bacteria (bacteria treating PP, BTPP).ResultsUsing UTPP decreased nutrient intake compared to the control and treatment with tannase‐producing bacteria again significantly increased nutrient intake compared to the UTPP (p < 0.05). The digestibilities of organic matter, neutral detergent fibre and acid detergent fibre in the control treatment were significantly higher than UTPP and BTPP and in the BTPP were significantly higher than the UTPP (p < 0.05). The use of UTPP in the diet significantly decreased the pH, ammonia nitrogen concentration and the total protozoa population of the rumen compared to the control (p < 0.05), and treatment with bacteria increased them again. The lowest total protozoa population was observed in UTPP treatments (p < 0.05). The highest concentration of blood glucose was observed in UTPP; however, the highest concentrations of blood urea nitrogen, cholesterol, triglyceride, high‐density lipoprotein (non‐significant) and low‐density lipoprotein were in the control treatment. The effect of experimental treatments on the dry matter consumption of the whole period was significant; however, there was no significant effect on average daily gain, feed conversion ratio, feed efficiency and longissimus muscle colorimetric systems.ConclusionsTherefore, considering the positive effects of treatment PP with tannin‐degrading bacteria relative to raw PP, using these bacteria is a proper way to reduce tannin, thus improving the nutritional value of PP for ruminants.
