Feed intake, milk production, and milk fatty acid profiles of dairy cows fed corn silage-based diets with different protein and starch concentrations were measured in a 3-period experiment in a changeover design using 12 Holstein cows. Each experimental period lasted for 3 wk. The diet fed as a total mixed ration consisted of 45% corn silage, 5% coarsely chopped wheat straw, and 50% concentrate...

Fumonisins are well known mycotoxins produced by Fusarium verticillioides, F. proliferatum and other Fusarium species. Many new fumonisins and fumonisin-like compounds have been detected by mass spectrometry in cultures of F. verticillioides. Recently, fumonisins B(2) and B(4) were produced by Aspergillus niger isolated from coffee and fumonisin B(2) in A. niger from grapes. Fumonisin B(2) was ...

While corn contains only limited quantities of crude protein and amino acids, corn by-products often contain crude protein and amino acids in appreciable amounts. The reason for this difference is that corn by-products are often produced after processing that primarily removes the nitrogen-free extracts (i.e., the starch) from the corn kernel. Because starch is approximately 70% of the total co...

Corn is a commonly used ingredient in dry pet foods because there is a stable supply and it is a relatively inexpensive source of nutrients. Corn hybrids are available that are higher in CP and amylose and lower in phytate concentration than conventional hybrids. Approximately 500 mg of high-protein (HP), high-protein, low-phytate (HPLP), and high-amylose (HA) corn were compared with convention...

Cereal Chem. 83(5):569–575 The effects of amylose, protein, and fiber contents on ethanol yields were evaluated using artificially formulated media made from commercial corn starches with different contents of amylose, corn protein, and corn fiber, as well as media made from different cereal sources including corn, sorghum, and wheat with different amylose contents. Second-order response-surfac...

1. Surface-labelling of starch granules by tritiation seems feasible, and a technique is described that could be useful in structure determination. The impurities that are produced must be taken into account but the fact that a high polymer can be successfully tritiated seems very promising. 2. The surfaces of corn-starch granules must contain both amylose and amylopectin.

The objectives of this research were to evaluate the intraand interpopulation variability in gelatinization properties of starches from exotic corn lines and their derivatives when grown 1) during two successive years in the same location; and 2) in both temperate and tropical environments. Six novel exotic corn lines (two 100% exotic and four 25% exotic derived from a breeding cross developed ...

Expansion of native corn starch produces a high surface area mesoporous material capable of acting as a novel stationary phase for separating various mixtures of compounds.

Sago starch is a locally grown and produced starch resource in Malaysia. In this study, corn starch to sago starch ratios (CS:SS) of 0:20, 5:15, 10:10, 15:5 and 20:0 were included in feed mixture to contain 20% starch and produce five isonitrogenous and isocaloric (30% crude protein and 16.7 kJ/g, respectively) tilapia Oreochromis sp < em>. diets. Diets were preconditioned to contain 40% moistu...
