“…The lack of effect of SHE or PPE supplementation on fiber digestibility is consistent with Abarghuei et al (2013), who reported the absence of negative effect of pomegranate extract on fiber digestion. They also reported that supplementation with pomegranate extract slightly improved ruminal pH, which favors fiber digestion.…”

Effect of sainfoin hay and pomegranate peel extracts on in vitro fermentation and protein degradation using the RUSITEC technique. Can. J. Anim. Sci. 95: 417Á423. The objectives of this study were to determine the effect of supplementation of sainfoin hay extract (SHE) and pomegranate peel extract (PPE) on in vitro rumen fermentation characteristics, protein metabolism and nutrient digestibility using rumen simulation technique (RUSITEC). The experiment was a completely randomized design with three treatments and four replications. Dietary treatments were: (1) control (10% barley silage and 90% concentrate), and control supplemented (2) with SHE (4.1 g catechin equivalent kg(1 dry matter; DM) or (3) with PPE (2.8 g tannic acid equivalents kg(1 DM). The experiment consisted of 10 d of adaptation and 7 d of data collection. Concentration of total volatile fatty acid (VFA) was lower (PB0.02), but molar proportion of acetate was higher (PB0.01) with SHE or PPE than control. Branched-chain VFA decreased (PB0.01) with PPE supplementation compared with control. Concentrations of large and small peptides were not affected but ammonia nitrogen (NH 3 -N) concentration decreased (P B0.01) with PPE supplementation. Digestibility of DM, starch and crude protein decreased (PB0.02) with SHE and PPE supplementation compared with control. Bacterial nitrogen production (mg d(1 ) and bacterial efficiency (g bacterial nitrogen kg(1 digested organic matter) were not affected by SHE or PPE supplementation. Overall, there were no differences in VFA concentrations, nitrogen fractions and nutrient digestibility between SHE and PPE except for the concentrations of branched-chain VFA and NH 3 -N, which were higher (PB0.01) with SHE versus PPE supplementation. In conclusion, supplementation of high-grain diet with SHE or PPE can decrease rumen by-pass protein; however, suppression of feed fermentation may decrease the feeding value of high-grain diet.

“…Many recent studies have shown that PSM have potentiality to improve rumen fermentation and GP favorably, at relatively low and moderate concentrations (Jiménez-Peralta et al 2011;Salem et al 2011Salem et al , 2014Bodas et al 2012;Salem 2012;Abarghuei et al 2013). In this study, PSM may suppress protozoal populations, increase bacterial and fungal populations, and microbial activity with decreasing methanogenesis which will be positively reflected in the form of increased amino acid flow to the duodenum (Mueller-Harvey 2006) and more muscle deposition and greater milk production (Abarghuei et al 2013). The GP is generally a good indicator of digestibility, fermentability and microbial protein production.…”

“…From these explanations we can expect that administration of plant extracts, rich in plant metabolite compounds, to ruminants will be reflected on improved animal performance in form of productive performance (milk, Abarghuei et al 2013; average daily gain, Salem et al 2011Salem et al , 2014 in addition to reproduction (Patel et al 2011).…”

This study was conducted to investigate the effects of increasing levels of extracts of Byrsonima crassifolia, Celtis pallida, Enterolobium cyclocarpum, Fraxinus excelsior, Ficus trigonata, Phoradendrom brevifolium and Prunus domestica on in vitro gas production (GP) and ruminal fermentation of a high concentrate diet. Plant extracts were prepared at 1 g dry matter (DM)/8 mL of solvent mixture (methanol : ethanol : water, 1:1:8) and added at levels of 0, 0.6, 1.2 and 1.8 mL/g DM of a high concentrate diet. In vitro GP was recorded at 2, 4, 6, 8, 10, 12, 24, 48 and 72 h of incubation. Increasing addition of extracts linearly increased (P < 0.001), the GP24 , GP48 and GP72 (mL/g DM), and linearly decreased (P < 0.001), the discrete GP lag time. Moreover, increasing extract doses linearly increased (P < 0.001) the asymptotic GP and decreased (P < 0.001) the rate of GP. GP6 was not impacted by treatments and GP12 increased linearly (P = 0.01) with increasing addition of extracts. Rumen pH declined linearly (P < 0.05) with increasing doses of extracts added. As no interactions (P > 0.05) occurred between the extracts and doses, it could be conclude that all extracts positively modified rumen fermentation at doses of 1.2 to 1.8 mL extract/g diet DM.

“…Nutrient digestibilities of goat feeds are presented in Table IV. Result similarity to [36], Dietary PSP or SO had no effect on the TTAD of DM (P=0.152), whereas TTAD of EE, NDF and ADF tended to increase (P=0.064, 0.094, 0.072 respectively). The TTAD of CP tended to decrease (P=0.061).…”

The objective of this research was to investigate the effects of supplementing two feedstuffs, Pomegranate Seed Pulp (PSP) as a source of plant secondary compounds or Soybean Oil (SO) as an energy source in order to enhance production performance and milk quality of Saanen dairy goats. Eight lactating cross-bred goats were assigned to receive diets in a replicated 4 × 4 Latin square design with 4 periods of 14 d adaptation and 7 d of data and sample collection. The four dietary treatments were unsupplementation (CON), supplementation with dried Pomegranate Seed Pulp (PSP) at 120 g/kgDM, supplementation with soybean oil (SO) at 50 g/kgDM, and supplementation with SO at 50g/kgDM and PSP at 120 g/kgDM (PSPSO), of concentrate diets. The dietary treatments with similar iso-nitrogenous (166 g/kgDM) and forage to concentrate ratio (36:64) were used. BW change, DM intake, protein intake, total tract apparent nutrient digestibility, milk yield, lactose, solid-not fat, total solid content and yield and solid-corrected yield of goats were not affected (P>0.05) by dietary treatments. Intake of PSPSO diet by PSPSO goats appeared to improve components and yields of milk fat, protein, 4%fat-corrected milk yield, milk efficiency (FCM/DM intake), responsibility of marginal FCM yield and milk flanoids (P=0.05). Somatic cell count of goat milk (520,000 cells/ml) was decreased (P<0.01) by the use of PSPSO diet. In conclusion use of combination between dried Pomegranate Seed Pulp and Soybean Oil (PSPSO) of goat diet could increase milk protein content and yield, milk fat content and yield, fat corrected yield, fat quality and milk oxidative stability property.  Index Terms-pomegranate seed pulp, soybean oil, quality and quantity of goat milk, milk antioxidant capacity
