Feeding Value Of Grain Sorghum For The Lactating Sow, G. F. Louis, A. J. Lewis, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

Two experiments were conducted to investigate the effects of a corn-soybean meal (CSBM) and a sorghum-soybean meal (S-SBM) diet on reproductive performance and nutrient utilization by sows. In Exp. 1,75 sows (39 gilts; 36 primiparous) were fed either a C-SBM or a S-SBM gestation diet from breeding to d 109, On d 110, sows were assigned to lactation diets; half of the sows from each dietary treatment were assigned to a lactation diet based on the opposite grain. Sow weight change from d 54 to farrowing was greater (P < .06) for sows fed S-SBM than for sows fed C-SBM. There was no difference (P > SO) in weight change of sows during lactation. Feed consumption during …

Ec91-735 The Impact Of Nitrogen And Irrigation Management And Vadose Zone Conditions On Ground Water Contamination By Nitrate-Nitrogen, K.D. Frank, Darrell Watts, Andrew Christiansen, Edwin Penas

University of Nebraska-Lincoln Extension: Historical Materials

The single largest contaminant found in ground water samples taken throughout Nebraska is nitrate-nitrogen (nitrate-N). Much of it reaches the ground water as a "non-point source" contaminant leached out of the crop root zone.

Nitrate-N is essential to corn production. However, when leached from the crop root zone it can become a major source of ground water contamination. There are serious contamination problems in shallow aquifers beneath several river valleys in Nebraska. Increasing nitrate-N concentrations are beginning to appear in deeper aquifer.
