Silo-Guard for corn silage

Two corn silages (34 to 36% DM) were made August 4 and 5, 1976; one was ensiled without additive (control), the other with Silo-Guard added at 1.5 lbs. per ton of fresh crop. Silos were opened after 68 days, and each silage was full-fed to 15 yearling steers (3 pens of 5 steers) during a 91-day trial (October 12, 1976, to January 11, 1977). Complete-mixed rations contained 84% silage and 16% soybean meal supplement on a DM basis

Silo-Guard for forage sorghum silage

Two forage sorghum silages (29 to 30% DM) were made October 1 to 3, 1978; one ensiled without additive (control), the other with 1.5 lbs. of Silo-Guard added per ton of fresh crop. Silos were opened after 36 days, and each was full-fed to 15 yearling steers (3 pens of 5 steers) during a 90-day trial (November 9, 1978, to February 7, 1979). Rations contained 84% silage and 16% soybean meal supplement on a DM basis

CULBAC® and ADD-F® (formic acid) additives for sudangrass and high moisture shelled corn silages

Laboratory silos were used in three trials to evaluate sudangrass (slightly or moderately wilted) and high moisture corn silages, each receiving the following treatments: (1) control (no additive); (2) CULBAC® dry; (3) CULBAC® liquid; and (4) ADD-F® (formic acid). Although the 12 silages were well preserved visually, there were differences in their chemical compositions. Silages treated with CULBAC dry had the highest DM recoveries and probably the most efficient fermentations. As expected, formic acid restricted the amount of fermentation, but surprisingly, it did not improve DM recovery

High-moisture or dry corn, roughage sources, and protein supplements for short-fed finishing steers

Dry corn, stave ensiled high-moisture corn (HMC), stave ensiled HMC treated with urea, and Harvestore ensiled HMC were evaluated in a steer finishing trial. Alfalfa hay and corn silage were the roughages and soybean meal or urea, the nitrogen sources. There were no differences in steer performance for corn treatments, but steer performance was significantly improved when alfalfa hay rather than corn silage was the roughage. Urea supplements significantly depressed steer performance compared with soybean meal additions; a combination of urea and soybean meal gave intermediate performance

Probing a critical length scale at the glass transition

We give evidence of a clear structural signature of the glass transition, in terms of a static correlation length with the same dependence on the system size which is typical of critical phenomena. Our approach is to introduce an external, static perturbation to extract the structural information from the system's response. In particular, we consider the transformation behavior of the local minima of the underlying potential energy landscape (inherent structures), under a static deformation. The finite-size scaling analysis of our numerical results indicate that the correlation length diverges at a temperature $T_c$, below the temperatures here the system can be equilibrated. Our numerical results are consistent with random first order theory, which predicts such a divergence with a critical exponent $\nu=2/3$ at the Kauzmann temperature, where the extrapolated configurational entropy vanishes.Comment: 5 pages, 5 figures, to appear in Phys.

Cold-flo, Sila-bac, and Silo-Best for corn silage

Four corn silages (41 to 46% DM) were made August 23 to 26, 1978; treatments were: 1) no additive (control), 2) 8.16 lbs of Cold-flo ammonia per ton, 3) 1.0 lb of Sila-bac per ton, and 4) 1.0 lb of Silo-Best per ton. Silos were opened after 139 days and each was full-fed to 15 heifer calves (3 pens of 5 calves) during a 112-day trial (January 12 to May 4, 1979). The complete-mixed rations contained 88% silage and 12% supplement (Table 19.1). Control silage was supplemented with soybean meal for one group of heifers and urea for another group (urea supplying 33% of the total ration crude protein equivalent). The Cold-flo silage was fed with a milo supplement with no additional crude protein added. Sila-bac and Silo-Best silages were supplemented with soybean meal

Urea and Fermentrol® additives for forage sorghum silage

Adding urea to forage sorghum greatly increased the ensiling temperature, produced a more rapid and extensive fermentation, and resulted in more shrink loss in the silo. Fermentrol®, an enzyme-inoculant additive, had very little affect on the silage temperature or chemical composition, but it did reduce the shrink loss. Calves red urea-treated silage had the poorest performance. Control and Fermentrol® silages each produced about 90 lb of calf gain per ton of crop ensiled, however urea silage produced only 60 lb. All three silages had short bunk lives throughout the trial

NaOH wheat silage and alfalfa haylage for growing steers and heifers

Wheat silage, with and without sodium hydroxide (NaOH), was fed, with or without alfalfa haylage, in an 80-day growing trial. Calves fed NaOH-silage consumed 18% more feed and gained 16% faster than those fed control silage, but feed efficiencies were similar. When 50% of the wheat silage was replaced with alfalfa haylage (DM basis), gains decreased 3.1 and 3.7%, feed intake increased 12.3 and 9.7%, and feed efficiency decreased 23.7 and 14.4% for calves fed control and NaOH silages, respectively. NaOH increased ensiling temperatures by 9 to 12° C during the first 6 weeks. Dry matter recovery from the concrete stave silos was similar for both silages (82.1% for control and 83.9% for NaOH); recoveries from buried bags were 92.3 and 89.5%. NaOH wheat silage was more stable in air than was either control wheat silage or alfalfa haylage

Whole-plant forage and grain sorghum silages for growing cattle

Four trials were conducted to determine the feeding value of whole-plant forage and grain sorghum silages. In general, growing cattle fed grain sorghum hybrids (NK2778, Funk\u27s 550, DeKalb 42Y, DeKalb E67) out performed those fed forage sorghum silages. Only moderate to high grain-content, forage sorghums (Buffalo Canex, Pioneer 947, Acco 351) gave performances that approached the grain sorghums. Low grain-content and nonheading forage sorghums (DeKalb 25E, Funk\u27s G-1990) resulted in the poorest cattle performance. These studies indicate that grain content of a sorghum silage is the major determinant of cattle performance and that whole-plant grain sorghums should produce the fastest and most efficient gains in growing programs

Drought-stressed, irrigated, and additive-treated corn silages for growing cattle

Cattle fed drought-stressed corn silage gained about 10% slower but were just as efficient as cattle fed irrigated corn silage. Because the irrigated corn out yielded the drought corn (17.4 VS. 8.2 tons per acre), the irrigated silage gave a much higher cattle gain per acre (1928 VS. 940 1b). Silo Guard II®-treated silage had an advantage in DM recovery and feed conversion over its control and produced 4.6 more pounds of cattle gain per ton of crop ensiled. Cattle fed H/M Inoculant®- treated silage gained significantly faster than cattle fed the control, however, the treated silage gave only slight improvements in DM recovery and gain per ton of crop ensiled
