Inhibiting effect of shallow seed burial on grass weed emergence
weed control seedling emergence
2016/2/22
The efficacy of superficial tillage as a sustainable tool to reduce the emergence of Digitaria sanguinalis, Setaria viridis, and Sorghum halepense was evaluated with field experiments. Seeds were buri...
Chemical characterization and in vitro biological activity of four tropical legumes, Styzolobium aterrimum L., Styzolobium deeringianum, Leucaena leucocephala, and Mimosa caesalpiniaefolia, as compared with a tropical grass, Cynodon spp. for the use in ruminant diets
rumen fermentation gas production kinetics PEG
2015/6/23
Kinetic parameters were estimated
by an exponential model. STA, STD, and LEU contained higher (P < 0.05) crude protein than MIC, which
had greater neutral detergent fibre and acid detergent fibre....
Effect of the type of non-fibre carbohydrates in grass silage-based diets on in sacco ruminal degradability and protein value of lupin (Lupinus angustifolius L. cv. Sonet) seeds ground to different particle sizes
cattle rumen degradability grass silage non-fibre carbohydrates lupin seeds particle size
2015/6/9
The study was conducted to find out the effects of the type of non-fibre carbohydrates (NFC) included in grass silage-based diets on in sacco degradability of dry matter (DM), crude protein (CP) and n...
Limnological changes in a pond ecosystem caused by grass carp (Ctenopharyngodon idella Val.) low stocking density
aquatic macrophytes water and sediment chemistry phytoplankton
2015/6/8
Grass carp (Ctenopharyngodon idella Val.) stocked (29 kg/ha) in a small pond reduced the biomass of aquatic macrophytes from 109 g/m2 to 33 g/m2 during one growing season. The only changes in hydroche...
The use of bacterial inoculants for grass silage: their effects on nutrient composition and fermentation parameters in grass silages
orchard grass silage bacterial inoculants
2015/6/8
The effect of three microbial inoculants (Lactobacillus plantarum CCM 4000, L. fermentum LF2, and Enterococcus faecium CCM 4231) on the fermentation and nutritive value of orchard grass silage was stu...
The effect of feeding diets markedly differing in the proportion of grass and maize silages on bovine milk fat composition
Keywords:Czech Pied cattle feeding diet
2015/6/8
Ten Czech Pied cows in the mid-lactation stage were fed diets based on grass silage and maize silage. The composition of milk fats differed. The proportions of even-chain saturated fatty acids (SFAs) ...
Effect of carbohydrates in grass silage-based diets on in sacco ruminal degradability of barley (Hordeum vulgare L. cv. Lomerit) grain ground to different particle sizes
cattle grass silage nonstructural carbohydrates
2015/6/8
The effect of carbohydrates included in grass silage-based diets on in sacco degradability of dry matter (DM), crude protein (CP), neutral detergent fibre (NDF) and cellulose (CE) of barley (Hordeum v...
