Animal productivity depends on the nutrient composition of the ration presented to the animal as well as on the quality of feed ingredients. In assessing animal productivity the nutritionist must determine if ration composition is the factor limiting productive potential. In order to do this one must have an accurate assessment of feed quality and delivery. Having as complete a set of informati...

This study estimated the fermentation characteristics and nutrient value of corn-lablab bean mixture silages relative to corn silages. The effects of feeding corn-lablab bean mixture silages on nutrient apparent digestibility and milk production of dairy cows in northern China were also investigated. Three ruminally cannulated Holstein cows were used to determine the ruminal digestion kinetics ...

There has been growing interest to develop forage rice as a new feed resource for livestock. This study was to characterize the natural population of lactic acid bacteria (LAB) and select potentially excellent strains for paddy rice silage preparation in China. One hundred and twenty-six strains were isolated and screened from paddy rice silage prepared using a small-scale fermentation system, ...

Six ruminally cannulated steers, five Holsteins and one Hereford (250 to 295 kg), were fed 84% forage sorghum silage plus 16% supplement or 50% forage sorghum silage plus concentrate and supplement diets containing either no addition (controls), 1% sodium bicarbonate (NaI-1CO 3 ) or 2% sodium bentonite in a 2 X 3 factorial arrangement of treatments in a 6 • 6 Latin-square experiment with 3-wk p...

background and objectives: ensiling is a conservation method for forage crops. it is based on the fact that anaerobe lactic acid bacteria (lab) convert water-soluble carbohydrates into organic acids. therefore, ph decreases and the forage is preserved. the aim of this study was to isolate special kinds of lactic acid bacteria from silage and to study the effect of bacteria, inulin and enzymes a...

The goal of making silage is to preserve as much as the original nutritive value of the crop as possible so that it can be fed throughout the year. Many factors affect the fermentation process and unfortunately the end result is not always good. Poor fermentations can lead to excessive run off, loss of nutrients, and production of spoiled silage that is no longer fit for feeding and must be dis...

the objectives were to investigate the effects of addition of alfalfa hay as an absorbent on fermentationquality and effluent production of corn silage. three levels of corn forage with dry matter (dm) contentsof 18.3, 21.7 and 25.5 percent were supplemented with 0, 5, 10, and 20 percent alfalfa hay, on as fedbasis, and ensiled in three replicates in polyvinyl chloride mini-silos in a completel...

in order to study the effects of sowing date and plant density on forage yield and some morphological characteristics of corn, an experiment was conducted in gorgon research station in 2008. in this experiment two sowing date (18 april and 21 june) and six plant densities (25000, 45000, 65000, 85000, 105000, and 125000 plant per hectare) were evaluated in form of factorial experiment (2×6) with...

OBJECTIVE The use of locally produced forage (LPF) in cattle production has economic and environmental advantages over imported forage. The objective of this study was to characterize the nutritional value of LPF commonly used in Korea. Differences in ruminal fermentation characteristics were also examined for the LPF species commonly produced from two major production regions: Chungcheong and ...

The effect of a homolactic inoculant containing a blend of Lactobacillus plantarum, Pediococcus acidilactici and Enterococcus faecium or, the anionic surfactant, sodium dodecyl sulphate (SDS), alone or in combination on fermentation characteristics, aerobic stability and in situ DM, OM and NDF degradability of barley silage was investigated. Barley (Hordeum vulgare, L.) was harvested (45% DM), ...
