The objectives of this experiment were to determine effects of reducing particle size on growth performance, carcass characteristics, stomach morphology, and VFA concentration in the hindgut of growing-finishing pigs if diets were formulated to a constant ME. Thirty-six gilts and 36 barrows (32.00 ± 1.58 kg initial BW) were individually penned and randomly allotted to 4 dietary treatments in a ...

A total of 182 lactating sows were used in a study to determine the threonine requirement, and the relative difference in resulting performance of lactation diets with high concentrations of crystalline amino acids, compared with a conventional corn-soybean meal diet. All experimental diets were based on corn-soybean meal and formulated to contain 0.88% true ileal digestible (TID) lysine (1.00 ...

Worldwide expansion of agriculture is impacting the earth’s climate by altering carbon, water, and energy fluxes, but the climate in turn is impacting crop production. To study this two-way interaction and its impact on seasonal dynamics of carbon, water, and energy fluxes, we implemented dynamic crop growth processes into a land surface model, the Integrated Science Assessment Model (ISAM). In...

One hundred ninety-two steers were fed cottonseed meal, soybean meal or urea supplemented rations in which the corn grain was fed whole (with 5 percent corn silage) or in the high moisture or steam flaked form (with 14 percent corn silage dry matter added). Rates of gain and feed efficiencies were approximately equal for steers fed soybean meal and cottonseed meal and slightly superior to those...

Soil balancing (SB), or base cation saturation ratio (BCSR), is a soil management approach that strives to maintain specific calcium (Ca) and magnesium (Mg) levels improve health, decrease pest problems, have better crops, increase crop yield. To achieve ideal of Ca Mg, BCSR practitioners apply gypsum (calcium sulfate) high-calcium lime (Hi-Cal lime) amendments, with the former increasing later...

Two 21-d trials were conducted to evaluate the effect of heating time and sodium metabisulfite (SMBS) on the nutritional value of full-fat soybeans for chicks. In Trial 1, four pen-replicates of eight chicks each were fed corn-based diets (19% CP; 3,167 kcal of ME/kg) containing either 44% CP soybean meal or full-fat soybeans. The soybeans either were unheated or were autoclaved at 121 degrees ...

This present study was designed to evaluate the effect of storage duration (1.5 years and 2.5 storage) on wheat quality impact inclusion stored in diet broilers performance, nutrient digestibility, carcass parameters. A total 560 one-day-old male were randomly assigned 56 pens, each pen had 10 birds. corn-soybean-based considered as control other six dietary treatments prepared by replacing cor...

Corn (Zea mays L.) is one of the key grain crops in China. In fields, two soybean (Glycine max and peanut (Arachis hypogaea L.), which have nitrogen-fixing capacity (NFC), are generally used to intercrop with corn improve plant physiology production ability even under fertilizer reduction. To explore a more scientific reasonable way corn, simultaneously reduce use chemical fertilizers pesticide...
