Pomegranate (Punica granatum L.) peel powder meal supplementation in broilers: effect on growth performance, digestibility, carcase and organ weights, serum and some meat antioxidant enzyme biomarkers

Abstract

This study determined the dietary effects of pomegranate peel powder meal (PPPM) supplementation on growth performance, digestibility, carcase and organ weights, serum, and some meat antioxidant enzyme indices of Cobb 500 birds. Birds (n ¼ 432) were randomly assigned to six experimental groups of four replicates each and were fed either diets supplemented with 2, 4, 6 and 8 g/kg of PPPM (PPPM2, PPPM4, PPPM6 and PPPM8), 0% additives (Negative control; NEGCON), or with a-Tocopherol acetate at 200 g/tonne (Positive control; POSCON). The diet  week interaction effect on feed intake (FI) and feed conversion ratio (FCR) showed that the POSCON diet promoted a better FI and FCR at week 3. However, the FCR of the POSCON birds was comparable to that of the NEGCON, PPPM 4 and PPPM6 birds. The average final body weight and average daily weight gain was highest in the PPPM 2 and PPPM 4 birds, whereas, PPPM 2 birds had improved FCR and protein efficiency ratio compared with the POSCON birds. Thigh weight was highest in the PPPM 4 group, whereas PPPM 8 birds had the highest breast weight compared with the POSCON. Birds fed the PPPM 4 diet also had improved nutrient digestibility compared with the POSCON birds. Spleen and gizzard weights were highest in PPPM 4 birds compared with the NEGCON group. The concentration of serum aspartate aminotransferase (AST) was decreased in PPPM 4 birds, whereas meat from PPPM 8 group had the highest catalase enzyme activity. It can be concluded that birds fed 4 g/kg PPPM outperformed the birds that were fed a-tocopherol supplemented (POSCON) diets in terms of performance, digestibility, carcase and organ indices. The effect of pomegranate peel powder meal supplementation was also pronounced in decreasing the concentration of AST at 4 g/kg and increasing the activity of catalase enzyme at 8 g/kg compared with the POSCON and NEGCON diets. HIGHLIGHTSDietary pomegranate peel powder can improve performance in broilers. Dietary pomegranate peel powder can enhance the enzyme activity of broiler meat.

“…This is due to the improvement of digestion and enzymatic secretions in the intestine. This increases the efficiency of utilizing nutrients because it contains biologically active compounds (Akuru et al, 2021). Fish survival rate is a crucial component of fish production; it is influenced by factors such as the availability and kind of feed, as well as the physical and chemical characteristics of the water (Kumar et al, 2017).…”

Post-Harvest Management and Value Addition in Pomegranate

“…Pomegranate peel powder meal (PPPM) supplementation in a-tocopherol supplemented (POSCON) diets to broiler Cobb 500 birds promoted feed conversion ratio and protein efficiency ratio. It improved average final body and other organ weights, spleen and gizzard weights, catalase enzyme activity, and nutrient digestibility, while it reduced the concentration of serum aspartate aminotransferase at concentrations of 4-8 g/kg feed [130]. Dried pomegranate peels can be used safely in sheep feeding at 1 per cent level to realize the best growth performance and depressed the price of ration cost and best relative economic efficiency [131].…”

Effects of dietary α-tocopherol acetate and pomegranate peel extract on growth performance and antioxidative potential and lipid oxidation of meat of broiler

“…However, natural antioxidants are more expensive and less effective than synthetic antioxidants (Gümüş et al, 2021). As a result, much special attention has been focused on natural antioxidants derived from inexpensive and phenolic-rich waste products resulting from the processing of fruits and fruit juice industry by-products such as pomegranate peel (PP) (Kishawy et al, 2019;Akuru et al, 2020Akuru et al, , 2021Ahmadipour et al, 2021).…”

“…Turkey is an important pomegranate producer and exporter in the World and its total production amounted to559 000tons in 2019 (Gungor et al, 2021).In Turkey, pomegranate fruit is generally processed into juice and juice concentrate, and its peel is an inedible by-product obtained during processing pomegranate into juice (Akuru et al, 2020;Ahmadipour et al, 2021). PPmakes up about50 % of the whole fruit, which is an important source of several bioactive compounds including hydrolyzable tannins, flavonoids, anthocyanins and other phenolic compounds (Gullón et al, 2020).The ability of these bioactive polyphenolic compounds in PP to act as a free radical scavenger on the active forms of reactive oxygen species, which has been implicated in the initiation and progression stagesof oxidation, is partly related to their standard one-electron donation, breaking the free radical chain reaction or preventing metal ion chelation (Sumathy et al, 2013;Kishawy et al, 2019;Akuru et al, 2020Akuru et al, , 2021.…”
