Corn harvested for silage is an important feed crop on most Pennsylvania farms, where cropland often is limited. The crop provides livestock producers with a high-yielding, relatively consistent source of forage and the animals with a highly digestible and palatable feed. Corn silage produces more energy per acre than any other crop grown in Pennsylvania. Corn silage serves as a high-energy for...

Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage is vulnerable to contamination by spoilage mol...

Khorvash, M., Colombatto, D., Beauchemin, K. A., Ghorbani, G. R. and Samei, A. 2006. Use of absorbants and inoculants to enhance the quality of corn silage. Can. J. Anim. Sci. 86: 97–107. This study examined whether inoculants and various absorbent materials could be used during ensiling to reduce effluent losses and improve nutritive value of corn silage. Two corn forages were harvested: conve...

Safflower (Carthamus tinctorius L:) usually grown as a source of oil can be also used as fodder either for hay or ensiling purposes, particularly in semiarid regions. In 2002-2003 a research project was carried out in Southern Italy to evaluate the production and forage quality of safflower biomass cv Centennial (high oleic), harvested at three different stage: May 14 (at complete appearance of...

An index of forage quality, milk per ton of forage DM (Undersander et al., 1993), was developed using an energy value of forage predicted from ADF content and DMI potential of forage predicted from NDF content as its basis. The milk per ton quality index was later modified for corn silage (Schwab et al., 2003) using an energy value derived from summative equations (Schwab et al., 2003; NRC, 200...

The objective of the present study was to characterize maize silage according chemical composition, yield, as well their predicted milk production. A search made on studies related density, composition (DM, CP, NDF, starch), and dry matter digestibility (DMD). In this study, 41 varieties from temperate regions 101 tropical origin were analyzed. net energy lactation (NEL Mcal/kg DM), kilograms p...

forage K concentration was 12 g kg 1 (Brown et al., 1969). Timothy stands should persist over time with a High K grass forage increases risk of animal metabolic disorders, concentration of 15 to 18 g K kg 1 in headed spring and forage management of perennial grass grown under K-limiting soil conditions needs further study. Our objective was to evaluate growth and 12 to 16 g K kg 1 in regrowth, ...

Ninety crossbred beef calves (277.7 ± 7.1 kg) were utilized in a completely randomized design to determine supplement and rumen undegraded protein (RUP) influence on calf performance while grazing stockpiled tall fescue. Calves were supplemented at 1.15% of BW DM with dried distillers grains w/solubles (DDGS); 80.7% DDGS, 19.3% AminoPlus (DDG19); 80.7% soybean hulls (SBH), 19.3% AminoPlus (SBH1...

To quantify the effect of a reduction in nitrogen fertilizer on grass intake and animal performance, four zero-grazing experiments were carried out, two in spring /early summer and two in late summer. Grass was fertilized at three levels of N fertilizer, 450, 300 and 150 kg/ha per year and harvested daily at dry matter yields between 1500 and 2000 kg/ha. Grass was fed ad libitum to three groups...
