the present study was carried out to evaluate the effects of dietary nano-structured zeolite (nz) levels on reduction of aflatoxin b1 (afb1) in the diet of rainbow trout (oncorhynchus mykiss) for 56 days. for this purpose, 270 fish (23 ± 3.7 g) were randomly distributed into 6 groups including c (control), nz0.5 (basic ration + 0.5 % nano-structure zeolite), nz1 (basic ration + 1 % nano-structu...

The influence of nutrition during the last trimester of pregnancy and the early postpartum period on postpartum LH secretion was evaluated in two-year-old Hereford and Simmental heifers maintained on a high or low plane of nutrition (experiment 1) or in Hereford heifers fed a high or low energy (150% vs 100% NRC) ration (experiment 2). Amount of LH released with 10 mg estradiol benzoate (IM) at...

An experiment was conducted to study the effects of feeding growing pigs a diet low in selenium (Se) and vitamin E (E) with and without supplementation of various levels of Se and/or E on tissue Se and serum tocopherol concentrations. Nine of 10 pigs fed the unsupplemented cull pea diet had lesions attributed to a Se-E deficiency and eight of these pigs died during the 135-day experiment. No de...

T HREE switchback metabolism studies were conducted to study the effects of replacing corn with 5, 10 and 15% cane molasses. Five percent molasses had no significant effect on any of the parameters studied. At 10 and 15% molasses added at the expense of corn in the basal ration, nitrogen retention and apparent digestibility of dry matter and energy were all significantly improved (P< .05) . The...

magnetite (feo.fe2o3) nanoparticles immobilized on silica and modified by treatment apolaccase were used to decolorize the industrial wastewater from basic red 9 (br9 by way of fenton and fenton-like processes. the surface changes to the silica were determined by scanning electron microscopy, fourier transform infrared spectroscopy, x-ray diffraction and energy-dispersive x-ray spectroscopy. th...

T HE experiment involved 48 pairs of male Holstein fraternal twin calves. Two methods of raising calves were contrasted: (A) High fat (20%) and protein (20%) vealer ration fed from 3 days of age to a market weight of 128 kilograms. (B) The same vealer was fed up to a live weight of 56.7 kg, followed by pelleted grain mixture fed ad libitum and hay offered to a maximum of 0.9 kg per day. Twin pa...

Metabolism and rumen moti l i ty studies were conducted using yearling wethers subjected to three types of noise (at 75 and 100-dB intensities): United States of America Standard Institute (USASI) white noise; instrumental music and intermittent miscellaneous sounds (IMS). Animals ate less (P<.05) when subjected to auditory stimuli that exceeded background noise (48 dB). IMS at 75 and 100 dM in...

BACKGROUND This study aimed to evaluate the flexural strength and microhardness of three different anterior composites after 10 000 thermocycles. MATERIAL AND METHODS The mechanical properties of a nano-fill composite (Filtek Ultimate Universal Restorative (FUR) (Enamel)), a nano-hybrid composite (Clearfil Majesty ES2 (ES2) (Enamel)), and a micro-hybrid composite (G Aenial Anterior (GAA)) wer...
