Nf96-310 Costs Of Harvesting And Hauling Corn Stalks In Large Round Bales, H. Douglas Jose, Lance L. Brown

This NebFact calculates the costs of harvesting corn stalks for either livestock fodder or industrial uses.

Alternate Day Supplementation Of Corn Stalk Diets For Ruminants With High Or Low Ruminal Escape Protein Supplements, R.M. Collins, R.H. Pritchard

South Dakota Beef Report, 1990

Two experiments were conducted to determine the effects of feeding soybean meal (SBM) and corn gluten meal (CGM) based, isonitrogenous supplements at 24- or 48-hour intervals on corn stalk utilization. Exp. 1. Yearling rams were fed either protein supplement as 100 g daily or 200 g on alternate days. DM1 was lower (Pc.10) for the CGM than SBM based supplements. Protein source and interval of feeding did not affect (P>.10) digestible dry matter intake (DDMI) or disappearance of dry matter (DMD), but an interaction was observed (P<.05) between protein source and interval of feeding. Nitrogen retention was greater for CGM (P<.10) and 48-hour supplementation (P<.01). However, an interaction between protein source and interval of feeding occurred (P<.10) for N retention. Exp. 2. Angus and Hereford x Anugs steers (119 head; 620 ± 1.9 Ib) allotted to 8-head pens were fed similar diets except supplements (46% crude protein) also provided 0 (OM) or 200 (200M) mg per head per day monensin. CGM supported higher (Pc.05) ADG and gain/feed (G/F) than SBM, but a protein by monensin interaction occurred (Pc.10) for ADG and GIF. There was an interval by monensin interaction for ADG (P<.10) and DM1 (P<.05). An interaction between protein and interval occurred for plasma urea N on day 1 (P<.01) and day 2 (P<.10) of the sampling period. CGM was an effective isonitrogenous substitute for SBM based supplements in these applications. Supplementation at 48-hour intervals supported higher N utilization. High intermittent dosages of monensin appeared detrimental to calf performance.

Alternate Day Supplementation Of High Escape Compared To Low Escape Protein Fed With Corn Stalks, R. M. Collins, R. H. Pritchard

South Dakota Beef Report, 1989

A study was conducted using four ruminally fistulated wethers to compare ruminal fermentation characteristics of corn gluten meal (high escape) and soybean meal (low escape) supplements to corn stalks. Supplements were fed at 24 or 48-hour intervals. Ruminal ammonia nitrogen (RNH3-N) concentrations were affected (P<.05) by treatment and treatment by hour interactions occurred. Soybean meal fed at 48- hour intervals (SBM48) resulted in the highest mean and peak RNH3-N concentrations, as expected due to the quantity of rumen degradable protein fed. Soybean meal fed at 24-hour intervals (SBM24) caused higher (P<.05) RNH3-N concentration than corn gluten meal fed at 24-hour intervals (CGM24) but not CGM48. Total VFA concentrations averaged over time were not affected (P> .I0) by type of protein supplement. Treatment by hour interactions were observed (Pc.05) for total VFA, because SBM24 resulted in higher VFA concentrations at several points in the 48-hour sampling period. The ratios of acetate:propionate: butyrate were similar, 74:18:7, 74:18:7, 74:18:8 and 74:18:8 for SBM24, SBM48, CGM24 and CGM48, respectively. Ruminal fluid pH values were …
