A popular approach to training feed-forward nets is to treat the problem of adaptation as a function approximation and to use curve fitting techniques. We discuss here the problems which the use of pure curve fitting techniques entail for the generalization capability and robustness of the net. These problems are in general inherently associated with the use of pure supervised learning techniqu...

Birds were given a new formulation of the Bacillus amyloliquefaciens B-1895 solid-state fermented soybean that retained the spores of the aforementioned organism. Mass dynamics, feed flow rate and broiler performance were observed to evaluate the efficacy of the formulation. At each time point, the live mass was greater than that of the control group, reaching a difference of 7-8% by day 28. A ...

Demand for nonsolar energy and concern about the implications of fossil fuel combustion have encouraged examination of energy use associated with agriculture. The United States is a global leader in pig production, and the United States swine industry is centered in Iowa. Feed is the largest individual input in pig production, but the energy consumption of the Iowa swine feed production chain h...

A fundamental rule regarding diet formulation is that you will never know the true value of anything. Although we have reasonably accurate estimates of the average requirements for most nutrients, we have less certainty regarding nutrient requirements of a specific herd or animal under specific circumstances. We have equations that accurately estimate the average dry matter intake for groups of...

The study was designed experimentally using a Completely Randomized Design, five treatments were repeated three times included the use of carboxymethyl cellulose as control much 5%, and treatment feed additives seaweed 75%, 10% 12.5%. parameters measured efficiency, rupture speed test, sink durability stability test moisture content Analysis Variance continued with Duncan's Multiple Distance Te...

Large fluctuations in milk and supplemental feed prices create anxiety and uncertainties. Profit margin may shrink rapidly when milk price goes down and supplemental feed prices go up. Thus, it is important that correct decisions are made to maximize return on supplemental feed expenses. The change in prices and milk production response to feed supplements are especially important because they ...

a total of 1440 arian chicks were used in this study to determine the effects of diet formulation methods on performance and blood parameters of arian chicks. eight diets were arranged in a 2×2×2 factorial design with 2 methods of energy expression (apparent (amen) and true (tmen) metabolizable energy corrected to n equilibrium), 2 methods of amino acids content of feeds (total (taaf) and diges...
