Effect of Phase Feeding Supplemental Fungus Myceliated Grain on Oocyst Excretion and Performance of Broiler Chickens

Abstract: An experiment was conducted to investigate Fungus Myceliated Grain (FMG) feed inclusion strategies for broilers and the effects of this feed on natural Eimeria oocyst excretion and bird performance. Two hundred ninety-four straight-run day-of-hatch broiler chicks were obtained from a local commercial hatchery and randomly distributed in seven treatment groups with three replications of 14 chicks as follows: 1) Control-No FMG; 2) 5% FMG-starter feed; 3) 5% FMG-grower feed; 4) 5% FMG-starter, grower, finisher feed; 5) 10% FMG-starter feed; 6) 10% FMG-grower feed and 7) 10% FMG starter, grower, finisher feed. Fecal oocyst count, mortality, live body and bursa weight were determined at the end of the 7 wk trial. Results showed that broilers in treatments 1 and 2 produced the highest counts of Eimeria, which was significantly higher than that of treatment 6 (p<0.05) with the lowest count of Eimeria. Mortality was not significantly influenced by treatments. There were significant differences in the live and bursa weights, but not in the relative bursa percent. The results suggest the best response in terms of anticoccidial protection occurs with the 10% inclusion in the growers feed and for body weight at the 5% inclusion level in the starter feed

Effects of feeding diets supplemented with fungus myceliated grains on some production, health and oxidation traits of dairy ewes

The beneficial properties of mushrooms bioactive compounds indicate their potential use as performance enhancing natural additive for livestock animals. This paper reports the preliminary results of a research on the effects of diets supplemented with fungus myceliated grains (FMG) to lactating ewes in terms of intestinal parasites control, milk production and cheese oxidative stability. During 8 weeks, 21 ewes were divided into 3 groups fed with hay ad libitum and 1.3 kg/day per head of one of 3 concentrates with 0, 10 or 20% of FMG. In front of analogous DM and nutrients intake, the ewes fed FMG at higher levels showed a reduction of intestinal parasite infection, a tendency to improve milk yield and a higher milk casein content. The increase of FMG in the diet was responsible of production of cheeses with a lower secondary lipid oxidation and a higher antioxidant capacity, suggesting a major oxidative stability of cheese fat and an enrichment of cheese in antioxidant compounds induced by the FMG. These preliminary results appear to be promising, and further investigations are recommended

White-Rot Fungi in Bioremediation

Bioremediation is defined as the application of biological processes to the treatment of pollution. Most research on the field of bioremediation has focused on bacteria, and fungal bioremediation (mycoremediation) has also been attracting the interest just for a couple of decades. The toxicity of many pollutants reduces natural attenuation of bacteria, but white-rot fungi (WRF) can challenge with toxic levels of the most pollutants. Fungi are robust organisms having very high tolerance to toxic environments, and this feature makes them ideal to use for bioremedial purposes. White-rot fungi are basidiomycetes that are capable of degrading a lignocellulose substrate. Extracellular enzymes involved in the degradation of lignin and xenobiotics by white-rot fungi include several kinds of laccases, peroxidases, and oxidases producing H2O2. Nowadays, great progress in this area may derive from modern molecular technologies, which may provide cheaper potential sources of various enzymes by means of genetically modified microorganisms or plants. This chapter explains the bioremediation and its application conditions and degradation mechanisms of the harmful compounds such as textile dyes, PAHs, chlorophenols, TNT, pesticides, and nylon
