Three trials involving 513 exotic crossbred steers were conducted to determine the effect of zeranol implanting in the suckling and growing phases on subsequent feedlot performance and carcass characteristics. Treatments were 1) unimplanted control, 0000; 2) implanted twice in the finishing phase, 00II; 3) implanted in the growing phase and twice in the finishing phase, 0III; 4) implanted in th...

This study was conducted to investigate the influence of dietary rapeseed meal (RSM) on growth performance, blood profiles, nutrient digestibility and economic benefit of growing-finishing pigs. A total of 120 growing pigs ([Yorkshire×Landrace] ×Duroc) with an initial body weight (BW) 29.94±0.06 kg were used in this experiment. Pigs were randomly allotted into 1 of 5 treatments in a randomized ...

Background: The prohibition of the use antibiotics in lamb feeding requires search for natural alternatives that can improve productive performance and ruminal fermentation parameters. Herbal mixtures function as cost-effective substitutes growth promoters since an extraction or purification process is not required. Methods: An experiment was conducted to evaluate effect Chebulic myrobalan, Ter...

In the finishing process of optical glass, polishing with ceria, silica or zirconia slurry is conventionally adopted. The machining process, however, has problems involving inefficiency and a detrimental impact on the environment. Therefore, it is strongly recommended that the process be replaced with fixed-abrasive machining, but conventional fixed-abrasive tools have problems relating to low ...

600 seven day-old ross broiler chicks were tested in a factorial experiment (2×5) with two levels of oil (three and six percent) and five levels of soybean oil and soapstock (100:0, 75:25, 50:50, 25:75 and 0:100) with four replicates. rations were isocaloric and isonitrogenus. the chicks of the rations with three percent fat had higher weight gain and lower feed intake and feed: gain ratio (p

The finishing and polishing of composite materials affect the restoration lifespan. The market shows a variety of finishing and polishing procedures and the choice among them is conditioned by different factors such as the resulting surface roughness. In the present study, 156 samples were realized with three composite materials, -microfilled, nanofilled and silorane-, and treated with differen...

The inclusion of high concentrations of DDGS (30%) in both the nursery and growing-finishing periods may result in negative effects on growth performance and carcass characteristics. Summary The objective of this experiment was to evaluate the efiects of high concentrations of distillers dried grains with solubles (DDGS; 30%) on growth performance and carcass characteristics ofgilts, duringgrow...

Roughness increases significantly after finishing procedures. The aim of this study was to assess by the atomic force microscope (AFM) the effect of finishing instruments on the surface roughness of composite resins. A nanofiller composite resin (Filtek Supreme, 3M-F) and a microhybrid composite resin (Point 4, Kerr-P) were selected. The finishing procedures were done with a 30-blade carbide bu...

Stainless steel pipe with fine hole and long size has recently been needed for the flow line of pure gas and liquid, which is used in the field of precision machinery. Inner wall polishing of the capillary is very difficult by ordinary finishing methods. High speed slurry flow finishing method developed by authors has been proved to have excellent polishing performance, but it has been needed a...

Based on the characteristics of solid magnetic abrasive and abrasive flow finishing, a new technology of viscoelastic magnetic abrasive finishing is presented. The theoretical micro model of viscoelastic magnetic abrasive tools is established, and influencing factors of a positive pressure are determined by force analysis. Finishing mechanism of micro-grinding, slipping, rolling and so on is an...
