Investigation in terms of digestive values, silages quality and nutrient content of the using pomegranate pomace in the ensiling of apple pomace with high moisture contents

Abstract

The purpose of present study was to determine the quality and in vitro digestion parameters in silages of 100% pomegranate pomace (PPS), 100% apple pomace (APS) and 50% pomegranate pomace + 50% apple pomace (PAPS). The digestion parameters of 10% or 20% using of these silages in total mix ration (TMR) of dairy cattle were researched. The dry matter (DM), crude protein, flavonoids, tannins and anthocyanins of pomegranate pomace were higher than those of apple pomace. Fibrous and nonfibrous carbohydrates of pomegranate pomace were similar to those of apple pomace. The silage DM losses in APS decreased with pomegranate pomace (p = .004). The silage density, gas-methane production, and estimated digestion values of PPS and PAPS were higher than those of APS (p < .05). Lactic acid and pH value of APS and the PAPS were higher than the PPS (p < .01). The using of PPS up to 20% in TMR decreased in vitro estimated digestion of TMR (p < .05). The using of APS or PAPS up to 20% in TMR was appropriate for in vitro results. As a result, ensilaging of apple pomace with pomegranate pomace can increase silage density, silage DM; and can decrease silage DM losses; and do not affect silage quality-digestion parameters.

The <i>in vitro</i> digestion of neutral detergent fibre and other ruminal fermentation parameters of some fibrous feedstuffs in Damascus goat (<i>Capra aegagrus hircus</i>)

“…The in vitro total gas and digestion values of pomegranate peel in the present study on rumen goat were higher than those of pomegranate pomace in beef cattle reported by Ebrahimi (2012) and Kara et al (2018a). Mirzaei-Aghsaghali et al (2011) found that in vitro ME and OMd gas values of pomegranate peel for rumen fluid of steer beef were 8.85 MJ/kg DM and 59.0%, respectively.…”

Effect of supplementation of urea on the nutritive value and fermentation characteristics of apple pulp silages

“…The digestible organic matter content of apple pulp has been consistent with the research findings reported by Mirzaei-Aghsaghali et al (2011), while the content of apple pulp silage DOM was higher than the results reported by Abdollahzadeh et al (2010) and Kara et al (2018).…”

“…(2001) and Islam et al (2014) were also reported by. Although the NDF and ADF content detected in apple pulp silage was lower than those determined by Fang et al (2016), it was found higher than the data determined by Kara et al (2018). The amount of NDF (45.3%) and ADF (38.0%) found in this study were similar to the data reported by Abdollahzadeh et al (2010).…”

Nutritional composition of herbage of different Jerusalem artichoke genotypes

“…Anaerobic fermentation of forage and highfibre feed generates methane that contributes to global warming and waste of feed energy. Recent researches thus have focused on methane emission levels of the forages (Lin et al, 2013;Kara et al, 2018). Different outcomes were reported about methanogenic effects and anti-methanogenic compound contents of different roughage sources (Kara et al, 2016;.…”
