Microbial utilization of raw agro-substrates by solid-state fermentation (SSF) leads to an effective enrichment of prefermented cereal-derived substrates (PCS) with oleaginous fungi being a source of γ-linolenic acid (GLA, 18:3n-6). Such method could open up new possibilities in animal nutrition. In this review, the nutritional effects of various PCS used as components of basal diets are summarized through the integrating related studies. PCS with two oleaginous fungi (Thamnidium elegans and Cunninghamella echinulata) as GLA sources were described. Apart from fatty acids, other related fermentation parameters i.e. digestibility of dry matter, neutral detergent fibre, acid detergent fibre, methane and ammonia concentration, short-chain fatty acid profiles and protozoal counts were taken into account. The effectiveness of GLA sources in increasing ruminal GLA outputs varied, depending on the filamentous fungi used, in the order C. echinulate > T. elegans, but efficiency also depends on the cereal substrate type. However, in vivo studies are needed to determine the impact of using cereal substrates enriched with oleaginous fungi as a source of GLA on rumen metabolism as well as the quality of ruminant meat and dairy products.

The effect of feeding common balm (Melissa officinalis L.) and combination of yarrow (Achillea millefolium L.) and common hawthorn (Crataegus oxyacantha L.) on sensory properties and oxidative stability (2-thiobarbituric method - TBA) of chilled and frozen chicken meat was investigated. The experiment was carried out on 90 one-day-old broiler chicks (ROSS 308) divided into three groups and fed for 41 days, as follows: control (C) with basal diet without supplementation, the second group (LB) with basal diet supplemented with ground common balm 20 g.kg-1, and the third group (YH) with basal diet supplemented with ground yarrow 20 g.kg-1 and hawthorn 10 g.kg-1. Supplementation with common balm, and especially with combination of yarrow and hawthorn, caused the significant reduction in lipid oxidation processes in chicken meat during chilling and freezing storage. In experimental groups (LB, YH) stored chilled or frozen significant lower amounts of TBA reactive products were found compared with control group (P<0.05). Thigh meat was more susceptible to lipid oxidation compared with breast meat. In addition, diets supplemented with plants had a positive effect on sensory quality of fresh or frozen (12 month) meat. On the other hand, organoleptic properties of breast muscles were not influenced by supplementation.
