“…Similar findings were observed in lactating goats fed an additive of 6 or 12% pomegranate seed pulp, resulting in little reduction in DM intake, milk yield, and milk solids yield (Modarasi et al 2011). In accord, a previous study showed negative lignin digestibility and low CP digestibility in sheep fed a TMR containing 51% PPM and 5•85% soluble phenolics, which demonstrated the formation of indigestible complexes between dietary protein and tannins in the digestive tract (Eliyahu et al 2015a).…”

“…In addition, in the present study the ensiled PPM contained less water soluble carbohydrate (0•42% WSC in DM PPM, Table 1) than the fresh PP or the concentrated extract of PP used in some of the previous studies (Shabtay et al 2008(Shabtay et al , 2012Jami et al 2012;Eliyahu et al 2015b). This difference in WSC content might attribute to the different effect on methanogenic activity observed in a previous study (Jami et al 2012) that showed increased rumen methanogenic population in cow fed 4% concentrated extract of pomegranate pulp, whereas in the present study a decline in rumen methanogenic activity was found due to 8% PP feeding (Table 3).…”

“…This led to development of advanced industrial technologies, which provide consumers with 'ready to eat' pomegranate grains and fresh juices (Shabtay et al 2012). This development increased global production of fresh pomegranate pulp (PP), which is usually very wet (∼20% DM) and may contain readily fermentable soluble sugars, resulting in spoilage under aerobic conditions (Eliyahu et al 2015b).…”

“…A previous study examined direct ensiling in glass silos of fresh PP solely or in a mixture with various drier feeds. Results showed that without addition of drier feeds, high fermentation losses occurred (about 20% of DM) accompanied with reduction of in vivo DM digestibility of the ensiled PP in sheep (Eliyahu et al 2015b). The best combination used for successful ensiling of PP in the glass silos was a mixture of fresh PP with soy hulls and corn silage at DM proportions of: 40:35:25, respectively.…”

“…In addition, inclusion of up to 4% concentrated extract of PP in the total mixed ration (TMR) of lactating cows, increased their milk production and improved their health status (Shabtay et al 2012). However, fresh pomegranate pulp contains high levels of soluble phenolics and NDF which impaired its voluntary consumption by sheep to a maximal level of 20% in concentrated or wheat hay based rations (Eliyahu et al 2015a, b). In view of these results, it was clear that restricted amount of ensiled PPM should be fed to the lactating cows, and therefore a level of 8% PP in the PPM-TMR was chosen for the present study.…”

Based on a previous ensiling study in glass silos of various pomegranate pulp (PP) mixtures, fresh pomegranate pulp (PP) was mixed with drier feeds including soy hulls and corn silage (40:35:25 on DM basis) and ensiled in 32 pressed bales (700 kg each) wrapped with stretch polyethylene film. This ensiled pomegranate pulp mixture (PPM) was included in lactating cow total mixed ration (TMR) at a level of 20% of DM (PPM-TMR). Performance and digestion experiment was conducted with two groups of 21 milking cows each, fed individually one of the two TMR: 1. Control TMR without ensiled PPM; 2. Experimental TMR which contained 20% ensiled PPM, including 8% PP as corn grain replacer. Voluntary DM intake of cows fed the control TMR was 5.04% higher than that of the PPM cows. In vivo digestibility of DM, OM, NDF, CP and fat were significantly higher in the control cows compared with the PPM group, but methane production in the rumen fluid was 25% lower in the PPM cows. A slightly higher milk yield (by 2.2%) observed in the control cows; however, milk fat content was 5.9% higher in the PPM cows. This was reflected in similar yield of energy corrected milk (ECM) and 3.97% increase in production efficiency (ECM/DM intake) of the PPM cows compared with the control ones. Welfare of the cows, as assessed by length of daily recumbence time, was in the normal range for both groups. Body weight gain was also similar in both groups. Data suggest that the level of 8% PP in the PPM-TMR used in this study was probably too high for lactating cows and should be lowered to 4% in order to achieve better performance.
