Nutritional and chemical evaluation of dried pomegranate (Punica granatum L.) peels and studying the impact of level of inclusion in ration formulation on productive performance of growing Ossimi lambs

Abstract

Background: By 2050, the world will need to feed an additional 2 billion people and require 70% more meat and milk. The increasing future demand for livestock products, driven by increases in income, population, and urbanization will impose a huge demand on feed resources. A huge quantity of fruit and vegetable wastes and byproducts from the fruit and vegetable processing industry are available throughout the world that encourages to using it as a new source feeds in animal ration formulation. Methods: Twenty-eight male growing Ossimi lambs used to study the impact of inclusion dried pomegranate peels (DPP) on productive performance and economic efficiency. In nutritional and chemical evaluation conducted, amino acids, minerals, vitamins, polyphenolic, and fatty acid compositions were determined. Experimental lambs were allocated to one of four complete feed mixture (CFM) containing 0, 0.50, 1.00, and 2.00% DPP for (CFM 1 , CFM 2 , CFM 3 , and CFM 4), respectively throughout the feeding period that continuous for 119 days. Twenty-eight lambs with aged 5-6 months with initial weight of 22.875 ± 0.38 kg were divided into four equal groups, each of 7 lambs and fed one of the four iso-nitrogenous that contains 17.1% CP and iso-energetic that contained 2.76% of ether extract (EE) and gross energy (GE) ranged from 4212 to 4214 kcal/kg DM.

Impact of Using Different Levels of Dried Pomegranate by- Prouductsas Feed Additives on Performance of Growing Barki Lambs

“…Data of Table (3) that illustrated the vitamin contents of DPP cleared that it contained 15.12, 5.02, 0.496, 0.395 and 0.131 mg/100 g for vitamin C , vitamin E, vitamin A , vitamin B1, vitamin B2 , respectively. The result values were in agreement with those established by (Rowayshed et al, 2013 andOmer et al, 2019). The presence of vitamins naturally in DPP is one of the most important factors that make DPP have an antioxidant, antimicrobial, and chemo preventive cancer properties.…”

“…So, it could be mentioned that DPP considered a major source of vitamins. These results demonstrated that DPB was a good source of nutritious macro and micro minerals (Omer et al, 2019).…”

“…Lately, by-products of Pomegranates, practically pomegranate peel extract, are increasing attention due to its therapeutic properties such as antioxidant, antimicrobial, anticancer and anti-inflammatory activities. (Omer et al, 2019 andChen et al, 2020). Shabtay et al (2008) illustrated that pomegranate peels enhanced a significantly (P<0.05) increased feed intake and weight gain in calves.…”

Effects of feeding pomegranate peel silage on feed intake and growth performance of Turkey bred sheep

“…However, result of the current study is in disagreement with Kotsampasi et al (2014) who stated that the addition of PP to the total mixed ratio (TMR) at concentrations of 0, 120, and 240 g kg -1 did not significantly affect live weight, live weight gain, DM consumption, and feed utilization. Omer et al (2019) who stated in their study that dried pomegranate peel can be used safely in sheep feeding at level of 1% because this level realized the best growth performance and depressed the price of ration cost and recorded the best relative economic efficiency (Omer et al, 2019).…”

Immunomodulatory Properties of Pomegranate Peel Extract in a Model of Human Peripheral Blood Mononuclear Cell Culture

“…The biologically active ingredients are present in the peel, seeds, and arils of the pomegranate. The pomegranate peel, consisting of 26-30% of the total weight of fruit [2], is considered the main medicinal part and contains different minerals, essential amino acids, sugars, unsaturated and saturated fatty acids, tocopherols, sterols, terpenoids, and high concentrations of polyphenols (anthocyanins, flavonoids, ellagitannins, and alkaloids) [1,3,4]. Ellagitannins, the primary polyphenols of pomegranate, consist dominantly of punicalagin, punicalin, ellagic acid, and gallic acid.…”
