Two trials were conducted to evaluate the influence of supplemental urea withdrawal on characteristics of digestion (Trial 1) and growth performance (Trial 2) of feedlot cattle during the last 40 days on feed. Treatments consisted of a steam-flaked corn-based finishing diet supplemented with urea to provide urea fermentation potential (UFP) of 0, 0.6, and 1.2%. In Trial 1, six Holstein steers (...
this study was conducted in two separate experiments. four rumen-cannulated sheep were allocated in the first experiment to evaluate date by-product (dbp) and date seed (ds) nutrients degradation in rumen. in experiment two eighteen fattening lambs were allocated in three different treatments (6 animals/treatment) to evaluate dbp effects on animal performance and nutrients’ digestibility. three...
portion of UIP and the amino acid spectrum of the UIP. Therefore, it is absolutely essential to measure or predict the relative amounts of MP (metabolizable protein) from microbes and UIP in any given feeding scenario. Both the production potential of the beef animal and microbial protein synthesis are driven by energy. It is impossible to predict MP supplied to the lower gut and MP needs of th...
The present study was conducted to evaluate the nutritional value and in situ degradation kinetics of eight high protein forage crops: alfalfa (Medicago sativa L.), forage oat (Avena sativa L.), mixed pasture, and ryegrass (Lolium multiflorum Lam.) pasture in early vegetative stages, two forage lupins (Lupinus albus L.) in early bloom stages, sugar beet (Beta vulgaris L.) and kale (Brassica nap...

Sixteen Holstein cows in midlactation were used in a 4 × 4 Latin square design to determine the effect of replacing alfalfa neutral detergent fiber (NDF), with NDF from a combination of whole linted cottonseed, dried distillers grains, and wheat middlings. The four diets were a basal control diet that was low in forage and fiber [(5.9 g of corn silage NDF and 6.1 g of alfalfa NDF/100 g of dry m...
In the present study we have developed the agar-fill method for the measurement of gastrointestinal-tract capacity (GTC) to replace the in vitro water-fill method. This would estimate GTC without using complex equipment and techniques, and can be applied to the measurement of GTC for small laboratory animals. We attempted to confirm the efficiency of the agar-fill method by investigating the re...
Neu differentiation factor (NDF), a member of the epidermal growth factor (EGF)-related peptide family, activates ErbB2 via heterodimerization with the NDF receptors ErbB3 and ErbB4. In a similar fashion, EGF receptor (EGFR) agonists induce heterodimers of EGFR and ErbB2. In this paper, we show that the ErbB2-overexpressing breast tumor cells SKBR3, AU565, and MDA-MB453 are growth inhibited by ...
A beef herd submodel was created for integration with other farm components to form a whole-farm model capable of simulating a wide range of beef production systems. This herd submodel determined the best available feed or feed mix to meet the fiber, energy, and protein requirements for each of up to six animal groups on the farm. The groups comprised any combination of cows, nursing calves, yo...
Six experiments were conducted to evaluate methods for measuring NDF in corn and distillers grains plus solubles. Methods included using sodium sulfite, α-amylase (AMY), amyloglucosidase, heat and steam with an autoclave, grinding methods, and a pre–fat extraction to decrease factors that interfere with measuring NDF accurately. Using sodium sulfite and AMY resulted in decreased (P < 0.01) corn...
