Enhanced Attraction To Blood By Pigs With Inadequate Dietary Protein Supplementation, David Fraser, D. E. Bernon, R. O. Ball

Nutrition Collection

In two experiments, 60 individually penned growing pigs were exposed daily to two sections of cotton cord, one of which had been soaked with pigs' blood and subsequently dried, while the other was plain. The animals' preference for chewing-on the blood-impregnated cord was quantified by direct observation. When fed a standard "control" diet of corn, barley, and soybean meal with mineral and vitamin supplements, the pigs had a clear but modest preference for chewing the blood-impregnated cord. Omission of the protein supplement (soybean meal) from the diet for 4 wk led to a major increase in attraction to blood and …

Alternate Day Protein Supplementation Of Corn Stalk Based Diets With High And Low Ruminal Escape Protein Sources, R. M. Collins, R. H. Pritchard

South Dakota Beef Report, 1991

Twenty-four crossbred wethers (88 ± .44 Ib) were utilized to determine optimal level of dietary CP when corn gluten meal (CGM) and soybean meal (SBM) based supplements were fed alternate days. Diets were arranged in a 2 x 3 factorial design with SBM and CGM fed at 8, 9 or 10% dietary CP. Supplements were top dressed on ground corn stalks at a rate of two times the daily required amount (19.78% DM basis). The collection term consisted of an 8-day total feces and urine collection. DM1 and DDMl were improved (P<.01) when CGM was fed and as dietary CP was increased by either supplement. Dry matter digestibility (DMD) decreased (P<.05) as dietary CP level increased. Neutral detergent fiber digestibility (NDFD) did not differ (P>.05) for protein source or dietary CP level. …

Grain Sources And Roughage Levels For Limited Feeding Backgrounding Programs, R. H. Pritchard, M. A. Robbins

South Dakota Beef Report, 1991

The effects of grain source and roughage level in limited intake feeding programs were evaluated in 622-lb steer calves. Supplemented diets were based on high moisture ear corn (HMEC), whole shelled corn (WSC) + hay to provide similar NDF to the HMEC diet, HMEC diet containing 10% hay and the WSC + hay diet formulated to contain NDF similar to HMEC + hay. Steer calves were blocked by weight and fed to achieve 2.2 Ib ADG for a 52-day period. Steers fed HMEC had higher (P<.01) ADG and lower (P<.01) feed/gain than WSC fed steers. Low crude protein in the hay source caused lower (P<.01) crude protein in WSC diets. Lower crude protein intake could have limited steer growth. NE utilization appeared more efficient (P<.05) for heavy weight block steers, reflecting NRC equation low sensitivity to modest differences in frame size. Roughage level did not affect performance and did not interact with grain source.

Comparison Of The Effects Of Three Different Grinding Procedures On The Microstructure Of "Old-Fashioned" Non-Stabilized Peanut Butter, Clyde T. Young, William E. Schadel

Food Structure

Three different grinding procedures were utilized to prepare "old-fashioned" non-stabilized peanut butters. A leading commercial brand of stabilized peanut butter was used for comparison. The microstructure of each non-stabilized peanut butter was then evaluated with light microscopy and compared to the microstructure of the commercial brand of stabilized peanut butter. Major findings include: (1) dense spatial relationships of protein bodies, starch grains, and cell and tissue fragments that exist in "old-fashioned " non-stabilized peanut butter as compared to the well-dispersed spatial relationships which exist in commercially prepared stabilized peanut butter; and (2) degree of homogenization in the nonstabilized peanut butters …

Amino Acid And Energy Interrelationships In Pigs Weighing From 20 To 50 Kilograms: Rate And Efficiency Of Protein And Fat Deposition, L. I. Chiba, A. J. Lewis, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Two experiments were conducted to investigate the relationships between amino acids and DE for pigs weighing 20 to 50 kg. In Exp. 1, there were three dietary lysine levels that were either adjusted (1.50, 2.35 and 3.20 g/Mcal DE) for five DE levels (3.00 to 4.00 Mcal/kg) or unadjusted (.45, .71 and .%% of the diet) for three DE levels (3.50 to 4.00 Mcal/kg). In Exp. 2, diets containing six 1ysine:DE ratios (1.90 to 3.90 g/Mcal) at two DE levels (3.25 and 3.75 Mcal/kg) were fed. Pigs were housed individuiiy, and could eat and drink ad libitum. When pigs weighed …

Ec91-269 Domestic Poultry Feed Formulation Guide, Earl W. Gleaves, Thomas W. Sullivan, F. John Struwe

University of Nebraska-Lincoln Extension: Historical Materials

This publication provides basic, practical information about nturition and diet requirements for poultry. Nutrient requirements, diet formulations, feed ingredient analyses, and feeding methods are ever changing. Feed cost is the largest single item of expense in producing poultry meat or eggs. Poultry producers should adopt a comprehensive feeding program based on sound nutrition principles tailored to a specific production purpose. This publication provides the basis for such a feeding program.

G91-1048 Average Composition Of Feeds Used In Nebraska, Rick Stock, Rick Grant, Terry Klopfenstein

University of Nebraska-Lincoln Extension: Historical Materials

Analyses of frequently used feedstuffs are shown on a dry matter basis in the following table. Because the moisture content of feedstuffs varies widely, formulating rations on a dry basis contributes to accuracay in feeding cattle, compared to formulating on "as-fed" analyses.

G91-1027 Protein And Carbohydrate Nutrition Of High Producing Dairy Cows, Rick J. Grant

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the protein and carbohydrate requirements for milk production by dairy cows, and feeding guidelines to meet those requirements.

Crude protein makes up 14 to 19 percent, and carbohydrates 65 to 75 percent of the total ration dry matter in common dairy cow diets. As milk production per cow increases above 19,000 to 20,000 pounds per year, understanding how these nutrients are used by the dairy cow for milk production allows the formulation of diets that optimize solids-corrected milk production.
