The Effect of Humic Substances on the Meat Quality in the Fattening of Farm Pheasants (Phasianus colchicus)

Abstract

Background: The effects of humic substances (HSs) on the carcass characteristics and meat quality traits of breast and thigh muscles were studied. Methods: In total, 200 pheasants were allocated to 4 treatments, each containing 50 birds. The control birds were fed a diet without additives (0% HS); the other treatment birds were fed diets containing HSs at 0.5, 0.75 and 1.0% from 1 to 90 days of age. At the end of the experiment, several carcass characteristics were measured and breast and thigh muscle samples were taken to determine the composition of several nutrients by standard laboratory methods and procedures. Results: The carcass weights of both males and females increased significantly (p < 0.05) in the 0.50 HS and 0.75 HS groups after supplementation with HSs. The same effect of humic substances in the 0.50 and 0.75 HS groups was found in the weight of breast and thighs (p < 0.05). Significantly (p < 0.05), the highest carcass yield in males and females was found in the 0.50 HS group. Conclusions: Feeding with a diet containing HSs can have a beneficial influence on the carcass parameters, decrease the crude fat content in the meat and change the profile of bioactive fatty acids in the breast and thigh muscles of broiler pheasants.

Food safety and food quality. Proceedings of the scientific papers

“…Humínové látky ako iónomeniče a chelatačné činidlá zvyšujú využitie dusíka (Rath et al 2006). Rovnako, zvýšenie obsahu bielkovín v stehennej svalovine vplyvom prídavku humínových látok do krmiva bolo zistené aj u bažantov (prídavok v 0,5 a 0,75 % koncentrácii) (Gálik et al 2023) a brojlerových kurčiat (prídavok v 0,8 % koncentrácii) (Semjon et al 2020). Signifikantne vyšší obsah sušiny/nižší obsah vody bol zaznamenaný vo svalovine moriek bez prídavku aditív než vo svalovine moriek, ktoré mali prídavok probiotík resp.…”

Na druhej strane, obsah tuku v stehennej svalovine bažantov bol významne znížený (Gálik, et al, 2023).…”

The impact of probiotics in the nutrition of calves on live weight gain and on health status

“…There are many feed additives applied in the diet of animals such as probiotics, prebiotics, synbiotics, phytobiotics and food industry waste which have a positive impact on the health condition of farm animals (Gálik et al, 2023;Rolinec et al, 2023;Hanušovský et al, 2020). For example, lactic acid bacteria are used for silage fermentation, other microorganisms can be used as a source of proteins or for providing amino acids, vitamins, etc.…”
