The enormous variety of substances which may be added to forage in order to manipulate and improve the ensilage process presents an empirical, combinatorial optimization problem of great complexity. To investigate the utility of genetic algorithms for designing effective silage additive combinations, a series of small-scale proof of principle silage experiments were performed with fresh ryegras...

Silage normally contains between 12 and 22 % crude protein (CP). While such levels 5 should be adequate for most productive livestock, in silages they are not. This is because of poor 6 utilization of N in silage. Most silage-based production rations require supplemental protein to meet 7 requirements for growth or lactation in ruminants. Silage protein is highly degradable in the rumen and as ...

OBJECTIVE Effects of newly isolated Lactobacillus plantarum on the fermentation and chemical composition of fresh rice straw silage was evaluated in this study. METHODS Lactic acid bacteria (LAB) from good crop silage were screened by growing them in MRS broth and a minimal medium with low carbohydrate content. Selected LAB (LAB 1821) were Gram-positive, rods, catalase negative, and were iden...

the effects of a microbial inoculant (containing propionic and lactic acid bacteria) and formic acid onchemical composition, ruminal degradability of dry matter (dm) and nutrient digestibility of corn silage wereexamined. whole-plant corn was ensiled for 60 days in plastic polyethylene bags, and three treatments werecompared, 1: control (no additive), 2: propionibacterium acidipropionici plus l...

The effect of silage additives on ensiling characteristics and nutritive value of Napier grass (Pennisetum purpureum) silages was studied. Napier grass silages were made with no additive, fermented juice of epiphytic lactic acid bacteria (FJLB), molasses or cassava meal. The ensiling characteristics were determined by ensiling Napier grass silages in airtight plastic pouches for 2, 4, 7, 14, 21...

Additives for silage preparation were tested on their effect on the composition of whole crop maize silage and their potential to improve methane production from energy crops in anaerobic digestion plants. Treatments included ensiling without additives, inoculation with silage starters containing homofermentative lactic acid bacteria or a mixture of homoand heterofermentative lactic acid bacter...

the objective of the present study was to investigate the effects of bacterial additives on chemical characteristics and ruminal degradability of alfalfa silage. in this experiment the treatments consisted of: 1-untreated alfalfa silage (control), 2-treated with ecosyl (ec), 3- lacticil maize (lm), and 4- a combination of both additives, ec and lm, at half level of treatments 2 and 3. silos wer...

In the production of fermented feed, each crop can be contaminated with a variety of microorganisms that may produce natural pollutants. Biogenic amines, mycotoxins, and undesirable organic acids can decrease health feed safety. The aim of this study was to compare the counts of microorganisms, levels of biogenic amines, and the mycotoxins in forage legumes, and also to compare the occurrence o...

Introduction Various microorganisms, enzymes, nutritive and chemical compounds have been added to forages to maintain or improve the nutritive value of a crop as silage (Kung et al., 2003). As is the nature of most biological systems, there is considerable variation in the outcome of using these additives. This paper will briefly discuss some universal and specific challenges that these additiv...

It is difficult to make good quality of silage from alpine gramineous from the Qinghai Tibetan plateau. The effects of lactic acid bacteria (LAB) on the fermentation quality and aerobic stability of Siberian wildrye silage were studied in southeast of the Qinghai Tibetan plateau. Siberian wildrye materials were freshly cut at the sprouting stage, flowering stage, and milky stage. Silage was pre...
