The effect of a phytogenic additive on nutritional composition of turkey meat

Abstract

The aim of the study was to analyze the effect of a blend of phytogenic additive on nutritional and mineral composition of breast, thigh muscles and liver in fattening turkeys. A total 300 female turkeys were monitored in the trial. 1-day old broadbreasted white turkeys hybrid XL were randomly divided into two groups (150 pcs per each). Turkeys in control group were fed by standard diet for fattening and in experimental group from the 1st to the 12th week by complete feed mixture with supplementation of a blend of essential oils from origanum, anise and citrus fruits as well as a prebiotic rich fructooligosaccharides in dosage 1 kg per 1000 kg of feed mixture. Turkeys were housed in group on deep litter. Experiment lasted 18 weeks. Samples of breast and thigh muscles, and liver for nutritional analysis were collected during turkey's dissection (10 samples per each group). After the determination of nutrients, there were found significant (P ˂ 0.05) differences between control and experimental samples of breast muscles in content of crude protein and fat. Statistically significant (P ˂ 0.05) differences in all analyzed nutrients in thigh muscles were observed. The phytoadditive supplementation markedly (P ˂ 0.05) increased content of crude protein in breast (from 91.13 to 93.7% of DM) and thigh muscles (from 79.78 to 85.73% of DM) and ash in thigh muscle (from 4.25 to 4.61% of DM). Tendency of higher (P ˃ 0.05) content of DM and fat was recorded in liver. After analysis the macro and microelements, significant (P ˂ 0.05) differences in all minerals except potassium and manganese were found. Compare to the control group, in the experimental group were detected significantly (P ˂ 0.05) higher amounts of zinc in breast, magnesium and copper in thigh muscle samples. In the 1664 case of liver, there was found higher (P ˃ 0.05) concentrate only in content of manganese in experimental group. Occurrence of manganese was not observed in both muscles. 25Journal of Central European Agriculture, 2016, 17(1), p.25-39 DOI: 10.5513/JCEA01/17.1.Keywords: minerals, muscle, nutrients, phytogenic additive, turkeys Abstrakt Cieľom štúdie bolo analyzovanie vplyvu zmesi fytogenného aditíva na živinové a minerálne zloženie v prsnom svale, stehennom svale a pečeni výkrmových moriek. V pokuse bolo monitorovaných celkovo 300 jedincov samíc moriek. Morky plemena mäsový medzilíniový úžitkový kríženec morka širokoprsá biela, hybrid XL, vo veku 1 deň boli rozdelené do dvoch skupín (150 kusov v každej skupine). Morkám v kontrolnej skupine bola skrmovaná štandardná kompletná kŕmna zmes pre výkrm a v experimentálnej skupine od 1. do 12. týždňa bola skrmovaná kompletná krmná zmes s prídavkom zmesi esenciálnych olejov z oregana, anízu, citrusových plodov a prebioticky obohatená o fruktooligosacharidy v dávke 1 kg na 1000 kg kŕmnej zmesi. Morky boli ustajnené skupinovo na hlbokej podstielke. Pokus trval 18 týždňov. Vzorky prsného svalu, stehenného svalu a pečene, určené na analýzu živín, boli odobrané počas jatočnej rozrábky (10 vzoriek ...

Antioxidant activities and phenolic compounds in fruits of various genotypes of American persimmon (Diospyros virginiana L.) [pdf]

“…The fruits have also been used to make wine, brandy, white wine vinegar and beer (Bartram, 1772;Briand, 2005). Additionally, the by-products from processing persimmon fruits or leaves can be used in animal nutrition as a source of bioactive compounds Herkeľ et al, 2016) and thereby improve the performance of farm animals.…”

The effect of essential oils on quality and mineral composition of eggshell

“…The effect of dietary plant extracts added into feed mixture of layers on the content of phosphorus, calcium and magnesium in eggshell were not significant (Lokaewmanee et al, 2014). Herkeľ et al (2016) also reported that phytogenic additive including essential oil may significantly affect mineral composition in poultry products. Feeding olive oil along with conjugated linoleic acid completely prevented changes in the mineral content of eggs (Aydin et al, 2001).…”

Effect of Boswellia serrata Resin Supplementation on Basic Chemical and Mineral Element Composition in the Muscles and Liver of Broiler Chickens

“…Interactions in the content of nutrients in the animal organisms depend on the species, breed, sex, rearing system, health status, and the physiological-biochemical function of muscles and organs [ 47 – 49 ]. The interrelations between nutrients in the organism are strongly influenced by their content and availability in the diet as well as the status of the gastrointestinal microbiome, which can be optimized by application of appropriate dietary additives [ 5 , 10 , 50 , 51 ]. In the investigations conducted by Herkel et al [ 5 ], significant correlations were found between dry matter with crude protein and fat in breast and thigh muscles of fattening turkeys fed with a diet supplemented with a blend of essential oils from origanum, anise, and citrus fruits and fructooligosaccharides.…”

“…Additionally, phytobiotics increase the bioavailability of some micro- and macroelements, which are accumulated in tissues more easily. For instance, increased contents of Mg, Zn, and Cu were detected in poultry breast and thigh meat and in the liver [ 2 – 5 ]. Still, the poultry industry is seeking new nutrition solutions that can ensure a high level of production, which is inextricably associated with maintenance of a good health status of chickens throughout the feeding period.…”
