Dried Distillers Grain With Solubles In Laying Hen And Pullet Rations, Mahmoud K. Masa'deh
Department of Animal Science: Dissertations, Theses, and Student Research
The objective of this dissertation was to test different inclusion rates of dried distillers grains with solubles (DDGS) with or without enzyme supplementation. Study one was conducted to test DDGS at 0, 5, 10, 15, 20, or 25% on egg production parameter (24 through76 wk). As DDGS increased, egg wt. decreased during Phase I. However; no difference in egg wt. was observed during Phase II. Yolk color linearly increased with increasing DDGS level. Nitrogen and P retention increased as DDGS increased. Nitrogen and P excretion decreased with increasing DDGS. Study two was conducted to test DDGS inclusion of 0, 2.5, …

Two experiments were conducted to determine the effect of feeding wet distillers grains (WDGS) at 70% and wheat straw at 25% (DM basis) on finishing steer performance and N mass balance in open feedlot pens. Four treatments were tested as a 2x2 factorial with factors being diet and pen cleaning frequency (monthly or at the end of the feeding period). In both experiments the CON treatment (corn based diet) had greater DMI, ADG, HCW, marbling and fat depth. There was greater N intake and N excretion for both the WINTER and SUMMER experiments on the WDGS. Not all the additional …
