“…They show a diversity of biological activities (Silva et al, 2007), thereby influencing digestibility of forages. The results from the current study indicated that total phenols fall within a range that does not influence digestibility (Makkar, 2003;Abarghuei et al, 2014).…”

The objective of this study was to evaluate the nutritive value and anti-nutrient contents of Lablab purpureus (Lablab) and Vigna unguiculata (cowpea) and their effects on methane production in goats. Legume forages were grown and harvested at three stages of growth of pre-anthesis, anthesis, and post anthesis. Samples were collected at each stage and examined for proximate composition, total phenolics, condensed tannins, and saponins using standard methods. Hay was harvested at the anthesis stage and used in a growth study to evaluate the effects of forage legumes on methane production. Eighteen one-yearold goats, nine males and nine females, were used in the feeding trial. The goats were subjected to three treatment diets with six goats in each treatment, representing both sexes equally, for 60 days in a complete randomized design. Methane was measured with a laser methane detector (LMD). Cowpea showed higher ash (13.11%), acid detergent fibre (ADF) (38.42%), and crude protein (CP) (20.23%) than Lablab, which had values of 11.45 %, 36.17%, and 19%, for ash, ADF, and CP, respectively. Lablab had significantly higher fat content (2.41%), neutral detergent fibre (NDF) (49.27%), and hemicellulose (13.07%) than cowpea (2.1%, 46.91%, and 8.48%, respectively). The tannin, phenolic, and saponin content were influenced significantly by forage species and stage of growth. The diet and sex of the animal affected enteric methane production significantly. Forage legumes met animal requirements for fat, ADF, NDF, and CP. The energy and tannin levels of forage legumes were shown to reduce enteric methane production in goats.

“…In conventional processes, plant secondary metabolites are extracted from PP by using organic solvents (methanol, ethanol and acetone) which are costly techniques. It was verified that the extraction efficiencies of the secondary metabolites using organic solvents are comparable with that of water, which are less expensive and polluting (Abarghuei et al, 2013(Abarghuei et al, , 2014. Therefore, we hypothesized that inclusion of PPE to the diet would improve protein metabolism and milk fatty acids content.…”

An experiment was carried out to determine the effect of pomegranate peel extract (PPE) on nitrogen balance, blood parameters and the milk fatty acid profile of dairy cows. Four Holstein cows were used in a 4 Â 4 Latin square design with 28-d periods and 4 treatments: PPE0 (no extract), PPE400 (400 ml PPE/cow/d), PPE800 (800 ml PPE/cow/d) and PPE1200 (1200 ml PE/cow/d). Nitrogen balance, blood parameters and the milk fatty acid profile were measured. Determination of secondary metabolites showed its high content of aqueous fraction, total phenolics and total tannin with reasonable content of saponins. Outputs of N in milk were quadratically increased (P ¼0.044) by inclusion of PPE at 400 and 800 ml PPE/cow/d in the diet. Blood cholesterol (quadratic effect, P¼ 0.043), blood urea nitrogen (linear effect, P ¼ 0.047) and milk urea nitrogen (quadratic effect, P ¼ 0.0008) concentrations decreased with adding PPE. Supplementation with PPE quadratically lowered total saturated fatty acid (P ¼0.005), proportions of C12:0 (linear effect ¼0.040), C16:1c9 (quadratic effect, P¼ 0.011), C18:0 (linear effect, P ¼ 0.083, quadratic effect, P ¼0.011) and ω6/ω3 (quadratic effect, P ¼0.007). Amount of C18:3c (n-3) (linear effect, P¼ 0.046), DHA (C22:6) (quadratic effect, P¼ 0.009) and EPA (C20:5) (quadratic effect, P¼ 0.012) were increased by inclusion of PPE. Adding PPE lowered blood cholesterol, blood urea nitrogen and milk urea nitrogen. Milk from cows fed PE had significantly lower total saturated fatty acid, desirable ω6/ω3 ratio and higher content of EPA and DHA.

“…Baladi et al (2014) reported that higher doses of tannin extract of pomegranate pomace reduced in vitro gas production amount of soybean meal.

“…Negi & Jayaprakasha (2003) reported that concentration of ployphenolic compounds in acetonic extract of pomegranate peel was higher than that of methanolic and water extract. Abarghuei, Rouzbehan, and Salem (2014) and Abarghuei et al (2013) stated that addition of pomegranate peel extract in the rumen liquor, resulted in manipulate in vitro rumen fermentation products, decrease ammonia nitrogen concentration and protozoa population and increased microbial protein as well as propionic acid concentration and consequently production performance of ruminants. Baladi, Moghaddaszadeh-Ahrabi, and Afrouziyeh (2014) reported that when soybean meal treated with higher doses of tannins extracted from pomegranate pomace, in vitro gas production volume and consequently metabolizable energy (ME), net energy for lactation (NEl), digestible organic matter (DOM) content and short chain fatty acids (SCFA) production were reduced.…”

This study was conducted to investigate effects of supplementing different levels (0.0, 0.5 and 1.0% of buffered rumen fluid) of acetonic extract of pomegranate peel on rumen fermentation kinetics of sunflower seed meal (SFM), using in vitro gas production technique. The samples were incubated in syringes containing rumen liquor obtained from three cannulated Iranian Ghezel rams for 2, 4, 6, 8, 12, 24 and 36h. Results indicated that, addition of acetonic extract of pomegranate peel resulted in increase in gas production volume in all of incubation times (p < 0.0001). Amount of gas production, also increased by increasing dose of the extract. Amounts of a (the gas production from the immediately soluble fraction), b (the gas production from the insoluble fraction) and a + b (the potential gas production) for pomegranate peel extract supplemented sunflower seed meal were higher (p < 0.05) than that of control meal. Adding pomegranate peel extract resulted in increase estimated short chain fatty acids (SCFA) production as well as digestible organic matter (DOM), metabolizable energy (ME) and net energy for lactation (NEL) content of SFM. Production of SCFA as well as DOM, ME and NEL content of SFM increased (p < 0.05) by enhancing the level of the extract supplementation. In conclusion, it can be suggest that, supplementing acetonic extract of pomegranate peel may be lead to higher ruminal fermentation and better nutritive value of SFM in ruminants.
