This paper aimed to evaluate the productivity of corn crop for silage, beans and straw production in different rotation systems with spring/summer fall/winter green manures cultivated under agroecological management. The experiment was implemented a rural property managed an system since 2009, 2017/18 2018 crops. experimental design used randomized blocks, five repetitions. treatments consisted...

OBJECTIVE The objective of this study was to evaluate the effect of sodium diacetate (SDA) on fermentation profile, chemical composition and aerobic stability of alfalfa (Medicago sativa L.) silage. METHODS Fresh alfalfa was ensiled with various concentrations of SDA (0, 3, 5, 7, and 9 g/kg of fresh forage). After 60 days of the ensiling, the samples were collected to examine the fermentative...

The fixed metabolizable energy (ME) values from the NRC do not represent the true ME values of the various feedstuff used in livestock rations. Therefore, a rapid and effective method for evaluating the ME value of forage crops is required for proper ration formulation to improve production efficiency. Dairy goat digestion trials were conducted as the in vivo reference using the method of Menke...

Corn silage represents a mixture of highly digestible, energy-dense grain and a poor quality forage (stover). The value of altering the grain to stover ratio through agronomic and harvesting strategies has been recognized for some time, however many of these practices have been applied to hybrids selected primarily for grain yield and adapted for harvest as silage. Although the feeding value of...

The aims of this study were to compare the effects of sealing forage corn with a new oxygen barrier film with those obtained by using a conventional polyethylene film. This comparison was made during both ensilage and subsequent exposure of silage to air and included chemical, microbiological, and molecular (DNA and RNA) assessments. The forage was inoculated with a mixture of Lactobacillus buc...

In the central Great Plains, pastures and rangelands often are not economically competitive with grain crops. This has led to increases in acreages of row crops at the expense of rangelands, pastures, and hay crops on marginal lands resulting in severe erosion problems. The productivity of forages, pastures, and rangelands needs to be increased to levels that would make them economically compet...

The objective of the study was to examine how the fatty acid composition of milk especially concentrations of conjugated linoleic acids (CLA) and trans-C18:1 isomers and milk fat percentage were affected by silage type and concentrate level. Forty dairy cows were blocked and randomly assigned to one of four diets in a 2 x 2 factorial arrangement of treatments and a six week experimental period....

The objective of this study was to investigate the effects of chop length and inoculation of barley silage on feeding behavior, rumen fermentation, and growth performance of finishing feedlot steers. Barley forage (22-35% DM) was chopped to a theoretical chop length (TCL) of either 1.0 (short chop; SC) or 2.0 cm (long chop; LC) and ensiled without or with an esterase-producing bacterial inocula...

Limousin-cross steers (n=135; 258+/-26 kg) were used to compare forage vs grain feeding on carcass composition and palatability attributes of beef when time on feed was controlled. Diets included a 95% alfalfa silage ration (AS) or a 68% high-moisture corn, 25% alfalfa silage ration (HMC). These were incorporated into six treatments to allow comparisons of end points based on similar days on fe...

BACKGROUND In the normal process of bioethanol production, biomass is transported to integrated large factories for degradation to sugar, fermentation, and recovery of ethanol by distillation. Biomass nutrient loss occurs during preservation and degradation. Our aim was to develop a decentralized ethanol production system appropriate for farm or co-operative level production that uses a solid-s...
