Different techniques to assess bacterial community structure and diversity were evaluated in silages prepared with four different maize cultivars, three conventional and one transgenic (cv. Tundra, event Bt-176). Plants were cultivated in the greenhouse and harvested after 30 days of growth. Silage samples were collected at successive times during fermentation and analyzed for bacterial counts ...

The in sacco protein and protein-free dry matter rumen degradability of three feeds, concentrate, alfalfa hay and maize silage, was determined simultaneously in three animal species: four Mediterranean buffalo (Bubalus bubalis) bulls, four Friesian bulls and four Delle Langhe rams, which received four diets differing in forage:concentrate ratio (1 5 87.5:12.5; 0.75 2 5 75.0:25.0; 3 5 62.5:37.5;...

Beet pulp contains high amounts of pectins that can reduce the risk of rumen disorders compared to using feedstuffs high in starch. The objective was to study the effects of inclusion of ensiled pressed beet pulp in total mixed rations (TMR) for high-yielding dairy cows. Two TMR containing no or about 20% (on dry matter (DM) basis) beet pulp silage were used. The beet pulp silage mainly replace...

Intercropping of silage maize (Zea mays L.) and alfalfa (Medicago sativa is not a common practice because generally reduces grain biomass yield. The objective this research was to evaluate the productivity profitability maize–alfalfa intercropping, with goal establish increase in first year production. experiment conducted Fargo Prosper, ND, USA, 2014–2017. design randomized complete block four...

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...

According to EU legislation pigs must have access to rooting material, and the aim of the study was to quantify growing pigs’ preferences among six different rooting materials. The relative attractiveness of six rooting materials was assessed in an operant conditioning set-up using concurrent schedules of reinforcement. Twelve pigs were tested with all six combinations of the reference material...

________________________________________________________________________________ Abstract Diet composition has been suggested as a factor that influences the variability of responses when Saccharomyces cerevisiae (SC) is fed to ruminant animals. Diets based on lucerne hay (462 g/kg DM) and maize silage (488 g/kg DM) were fed to determine the effects of 0 or 5 g SC 47 (8×10 cfu/g) on ruminal dig...

The use of lignocellulosic biomass as a substrate in agricultural biogas plants is very popular and yields good results. However, the efficiency of anaerobic digestion, and thus biogas production, is not always satisfactory due to the slow or incomplete degradation (hydrolysis) of plant matter. To enhance the solubilization of the lignocellulosic biomass various physical, chemical and biologica...
