Different dietary cereal sources and fat types in the lactation diet were evaluated to investigate their effects on reproductive performance, milk composition, blood metabolites and hormones in multiparous sows. Twenty-four sows were randomly assigned to one of four treatments according to a 2×2 factorial arrangement of treatments. Each treatment had 6 replicates comprising 1 sow. Two cereal (c...

The Midwest is reeling from an infestation of corn blight. Over 200 farms in Iowa alone have reported infections. Plant pathologists note that the pattern of infestation is inconsistent with a natural outbreak since the infections occurred in many places at once and were found in farms along major interstate highways. Scientists found that the infecting strain is identical to one found in Asia....

The objective of this study was to examine the ethanol yield potential of three barley varieties (Xena, Bold, and Fibar) in comparison to two benchmarks, corn and wheat. Very high gravity (VHG; 30% solids) fermentations using both conventional and Stargen 001 enzymes for starch hydrolysis were carried out as simultaneous saccharification and fermentation. The grains and their corresponding drie...

the replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of holstein heifers have been evaluated. fifteen holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% ...

Corn silage serves as a high-energy forage for dairy cows. This is most important for high-producing herds and on farms experiencing problems with making or buying highquality hay crop forage. Corn silage, with its relatively highenergy content, is also well adapted for use in low-cost rations for fattening cattle. Corn silage requires less labor per ton to produce than many other forage crops....

in order to investigate the effect of crop rotation on relation of seed bank with nightshade (solanum nigrum l.) weed seedling population during the growth season of corn, a field experiment was carried out in dasht-naz crop company in sari, during 2012. at the first, farm was divided into 2×2 m networks and the cross points was signed and all sampling were taken from those points. sampling of ...

The aim of this experiment was to investigate the effects of partial replacement of corn silage with long alfalfa hay and/or coarse chopped wheat straw on biochemical parameters in late lactating Holstein primiparous dairy cows. Twelve late lactating Holstein primiparous cows including four cows equipped with a rumen cannula, averaging 210 ± 20 days in milk and weighing 575 ± 50 kg were randoml...

The relative suitability of potato and crops frequently grown in rotation with potato as hosts for Pratylenchus penetrans was evaluated. Suitability of rye, wheat, corn, oat, sorgho-sudangrass, and potato were compared in pot studies based on ratios of final population : initial population density and densities of nematodes in roots at harvest. Population densities increased more on potato, oat...
