“…Ricke hypothesized that the key to limiting S. Enteritidis during molt was to develop low-nutrient dietary strategies, such as formulations with high fiber content, that would still induce molt due to low energy density but were sufficiently fermentable to support an active GIT microflora that would serve as a barrier to pathogen establishment (255). Several molt diets with fermentable substrate combinations have been screened in vitro and shown to support optimal avian cecal fermentation (396)(397)(398) and retain similar cecal microbial molecular profiles (397). In vivo application of some of these diets was shown to retain fermentation and GIT populations during molt while limiting the ability of S. Enteritidis to colonize the GIT and become invasive (255,270,392,399,400).…”

SUMMARY Enteric pathogens such as Salmonella enterica cause significant morbidity and mortality. S. enterica serovars are a diverse group of pathogens that have evolved to survive in a wide range of environments and across multiple hosts. S. enterica serovars such as S . Typhi, S . Dublin, and S . Gallinarum have a restricted host range, in which they are typically associated with one or a few host species, while S . Enteritidis and S . Typhimurium have broad host ranges. This review examines how S. enterica has evolved through adaptation to different host environments, especially as related to the chicken host, and continues to be an important human pathogen. Several factors impact host range, and these include the acquisition of genes via horizontal gene transfer with plasmids, transposons, and phages, which can potentially expand host range, and the loss of genes or their function, which would reduce the range of hosts that the organism can infect. S . Gallinarum, with a limited host range, has a large number of pseudogenes in its genome compared to broader-host-range serovars. S. enterica serovars such as S . Kentucky and S . Heidelberg also often have plasmids that may help them colonize poultry more efficiently. The ability to colonize different hosts also involves interactions with the host's immune system and commensal organisms that are present. Thus, the factors that impact the ability of Salmonella to colonize a particular host species, such as chickens, are complex and multifactorial, involving the host, the pathogen, and extrinsic pressures. It is the interplay of these factors which leads to the differences in host ranges that we observe today.

“…It is believed that during the fermentation process in the caecum, the ratio between the acetate, propionate and butyrate should amount to 3-5:2:1 [29][30][31][32] . It is known that oversupply of zinc in diet causes an increase in acetate and propionate values and a decrease in the butyrate value [24] .…”

The study was conducted on 18 laying hens from Lohman Brown at 23 weeks of age. There were two research groups and one control group with six animals each. In the last four weeks of age, the animals were fed follows: Control group (Group C) complete diet; Group I diet containing zinc added via the biosorption process and; Group II: diet containing zinc as an organic chelate complex. The levels of short chain fatty acids (SCFAs) such as acetate, propionate, iso-butyrate, butyrate, iso-valeriate and valeriate were determined. It was observed that using a diet with additives obtained via biosorption does not have a negative influence on fermentation processes in the hen's caecum. ÖzetÇalışma 23 haftalık, 18 adet Lohman Brown ırkı yumurtacı tavuklarda yürütülmüştür. Araştırma altışarlı iki deney ve bir kontrol grubuyla yapılmıştır. Hayvanlar süreç içerisinde son dört haftada, aşağıdaki gibi beslenmiştir: Kontrol grubu (C) sadece yem; grupI çinko içeren biosorpsiyon prosesi ile, Grup II: organik şelat kompleksi olarak çinko içeren yemlerle beslenmişlerdir. Asetat, propiyonat, izo-bütirat, bütirat, izo-valeriat ve valeriat gibi kısa zincirli yağ asitlerinin düzeyleri belirlenmiştir. Burada katkı maddeleri ilave edilmiş yem kullanarak oluşturulan biozorpsiyonun tavuk körbarsağında fermantasyon prosesine olumsuz bir etkisinin olmadığı gözlemlenmiştir.

Methane production from co-digestion of grass with cow dung and silage with cow dung was conducted by a bioaugmentation technique. For self-fermentation, maximum methane yield (MY) of 176.66 and 184.94 mL CH4/g-VSadded were achieved at a ratio of grass to cow dung and silage to cow dung of 1:1, respectively. A higher maximum MY of 179.59 and 208.11 mL CH4/g-VSadded was obtained from co-digestion of grass with cow dung and silage with cow dung bioaugmented with anaerobic sludge at a ratio of 3:1. The solid residue left over after co-digestion at a ratio of 3:1 was pretreated by alkaline plus enzyme before used to produce methane and a maximum MY of 333.63 and 301.38 mL CH4/g-VSadded, respectively, was achieved. Overall power generated from codigestion of grass with cow dung plus pretreated solid residues and co-digestion of silage with cow dung plus pretreated solid residues were 0.0397 and 0.007 watt, respectively.
