“…The GS was of comparable quality with that used by Sinclair et al (2009) in all variables except for DM, which was greater in the current study. Overall, the GS was deemed to be of moderate quality due to being harvested at a relatively late stage of maturity.…”

“…There was no difference in the amount of N retained between the 3 forage treatments with an increased N output in the WCP silages attributable to an increase in urinary N. This provides evidence that the N contained within these forages was in excess within the rumen, absorbed into the bloodstream, and excreted by the kidneys (Lobley, 1992) potentially because of a lack of synchrony of energy and protein supply (Sinclair et al, 1993). Sinclair et al (2009) showed that approximately 0.76 of N in the WCP silages used here was immediately soluble within the rumen, with approximately 0.06 being RUP,…”

“…Silage, concentrate, and fecal GE were determined by adiabatic bomb calorimetry (model 1261, Parr Instrument Co., Moline, IL). The CT content of the silages was determined as described previously (Sinclair et al, 2009). Fecal samples were analyzed for NDF using the method of Van Soest et al (1991) with a heat stable cv-amylase without the addition of sodium sulfate and OM (Ministry of Agriculture, Fisheries and Food, 1986).…”

Two experiments were conducted to investigate the effect of inclusion of whole-crop pea (WCP) silages, differing in condensed tannin content, as a substitute for grass silage (GS) and soybean meal on lamb metabolism, performance, plasma metabolites, digestibility, and carcass characteristics. In both experiments lambs were offered either solely GS or a 50:50 mix on a DM basis of GS with either low-tannin (LTPS) or high-tannin (HTPS) pea silage ad libitum. Each forage mix was fed with either 400 g/d of low-protein (LP) concentrate or 400 g/d of LP with an additional 200 g/d of pelletized soybean meal (HP), resulting in 6 dietary treatments. Experiment 1 examined the effects of the diets on metabolism, digestibility, and N balance using 6 lambs in 4 periods of 21 d in an incomplete crossover design. Experiment 2 used 48 lambs and examined the effects of the diets on ADG, plasma metabolites, and carcass characteristics over 56 d. Both experiments were analyzed using a 3 × 2 factorial arrangement of treatments. In Exp. 1, lambs offered the LTPS diets had a greater (P < 0.05) digestibility of DM and OM than those offered the GS diets. Lambs offered the WCP silages had an increased (P < 0.05) N intake, N output, and digestibility of GE compared with those offered GS. Mean N digestibility was greatest (P < 0.05) in lambs offered LTPS. Lambs offered HP diets had increased (P < 0.001) digestibility of DM, OM, GE and N, and N- intake, output, retention, and digestibility compared with those offered the LP diets. In Exp. 2, there was no effect (P > 0.05) of forage type on intake, slaughter BW, or feed conversion efficiency (FCE). However, lambs offered the LTPS had a greater (P < 0.05) ADG than those offered the GS diets. Feeding diets containing HP increased (P < 0.001) total DMI, slaughter BW, ADG, and FCE. Lambs offered the WCP had a greater (P < 0.05) plasma β-hydroxybutyrate and urea concentration compared with those offered the GS diets. Feeding lambs HP diets increased (P < 0.05) plasma urea and total protein. Forage mix had no effect (P > 0.05) on carcass composition except for fat depth, which was greater (P < 0.05) in lambs offered WCP silage. Diets containing the HP increased (P < 0.05) carcass weight, hind leg circumference, chop dimensions, and kidney weight. It was concluded that lambs offered LTPS performed better than those offered GS and that LTPS has a concentrate sparing effect. Additionally, the increased tannin concentration in HTPS did not increase performance over lambs offered either GS or LTPS.

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.
