abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
The objective of this research was to determine the relationships between the morphological development and in situ ruminally degradable protein (RDP), ruminally undegradable protein (RUP), and microbial protein of two cool season grasses (intermediate wheatgrass and smooth bromegrass) and two warm season grasses (switchgrass and big bluestem). The initial growth of grass tillers grown near Mea...
Epichloë fungal endophytes are broadly found in cool-season grasses. The symbiosis between these grasses and Epichloë may improve the abiotic and biotic resistance of the grass plant, but some Epichloë species produce alkaloids that are toxic for livestock. Therefore, it is important to understand the characteristics of the grass-Epichloë s symbiosis so that the beneficial aspects can be preser...
Annual forbs form short-term persistent soil seed banks whereas perennial grasses form mostly transient ones in the central Monte desert. A conceptual framework predicts that annual forb seeds will have primary dormancy, whereas perennial grasses will have low dormancy levels. We assessed whether the dormancy traits of four annual forb species and five perennial grass species can account for th...
Switchgrass, Indiangrass, and big bluestem are warmseason grasses that are a suitable alternative for summer pasture in Iowa. Their advantage over cool-season grasses such as bluegrass, bromegrass, and orchardgrass is their ability to produce during midsummer. These warm-season perennial grasses start growing in late spring as air and soil temperatures increase. Leaf growth often occurs in earl...
grasses are natural homogenous group of plants and belong to the gramineae family (poaceae). the value of grasses to mankind has been recognized since the dawn of human civilization and culture of cereal grasses. in the present study, leptochloa uniflora hochst (poaceae) was subjected to antioxidant and phytochemical profiles using uv-vis, ftir and hptlc. antioxidant assays were studied using d...
