This study characterizes the changes in leaf mass, morphological composition and nutritional value of blades palisadegrass (Urochloa brizantha cv. Marandu) under continuous grazing first year implementation pasture after second eucalyptus planting an Integrated Crop-Livestock System Crop-Livestock-Forest, which were tested four seasons. The experimental design was random blocks, with three trea...

The objective of this trial was to determine lactation performance responses in high-producing dairy cows to a reduced-starch versus a normal-starch diet and to the addition of exogenous amylase to the reduced-starch diet. Forty-five multiparous Holstein cows, 68±29 d in milk and 696±62 kg of body weight (BW) at trial initiation, were randomly assigned to 1 of 3 treatments in a completely rando...

This study was conducted to evaluate post-weaning growth, carcass traits and parasite burdens St. Croix White (STX) and Dorper X St. Croix White (DRP) lambs grazing guinea grass pastures during the wet and dry seasons. Lambs (77 d of age) were placed in guinea grass pastures (0.5 ha) in a rotational grazing system. Fecal egg count (FEC), packed cell volume (PCV) and BW were measured weekly. Lam...

OBJECTIVE To analyze the sulfur content of water and forage samples from a geographically diverse sample of beef cow-calf operations in the United States and to estimate frequency and distribution of premises where forage and water resources could result in consumption of hazardous amounts of sulfur by cattle. DESIGN Cross-sectional study. SAMPLE POPULATION 709 forage samples from 678 beef ...

Twenty multiparous Holstein cows in midlactation grazed pastures of 4 forage mixtures in a 12-wk study repeated during 2 grazing seasons to determine if forage mixture complexity affected intake and productivity of lactating dairy cows. The forage mixtures were 1) orchardgrass plus white clover [2 species (SP)]; 2) orchardgrass, white clover, and chicory (3SP); 3) orchardgrass, tall fescue, per...

in order to evaluate the impact of different amounts of nitrogen fertilizer on growth and yield of two forage sorghum cultivars, a 2-year field experiment was carried out at the college of agriculture, shiraz university, shiraz, iran during 2010 and 2011 growing seasons. two factorial experiments were carried out in randomized block design with three replicates, in which the treatments included...

the effect of different salinity levels (1.7, 5, 10, 15 and 20 ds.m-1) on yield and forage quality of two millet cultivars (nutrifeed and bastan) was investigated in this experiment. a factorial test based on randomized complete block design with three replications was conducted during 2010-11 growing season. the results showed that with increase in salinity, dry matter yield decreased. the hig...
