    Farmers and ranchers must balance the additional cost of labor, fencing, fertilizer and machinery against profits when selecting a workable management system for their farms. Milk composition of cows during mid to late lactation is more sensitive to changes in ration composition than is milk composition of cows during early lactation. Heterosisis the phenomenon where in the crosses between inbreed lines or parned populations are exceed. IWG grain yields were about lb per acre and a spring harvest did not affect grain yields.

    Optimum N fertilizer rates for intermediate wheatgrass grain production Experimental design will be a randomized complete block with treatments in a split-split plot arrangement and four replicates at each site. Experiment being conducted for 2 years and grain yields measured. Then they input this field data into their farm model to evaluate the environmental dynamics of four different dairy farms in all types of weather over 25 years. Herrera-Saldana, R.

    Jorgensen, and G. Browse Tags. The model generated estimates for ammonia emissions from manure, soil denitrification rates, nitrate-leaching losses, soil erosion, and phosphorus losses from field runoff. Neutral detergent fiber is the best expression of fiber available currently, but recommendations are also given for ADF because of its widespread use.

Impacts The visiting scientist has instituted several practices that will allow greater uniformity of results from commercial forage testing laboratories. Publications Undersander, D. Elective Fiber The effective fiber concept is an attempt to formulate diets not only for NDF but also for the ability of a diet to Methods of measuring pasture yields with dairy cattle book chewing Sudweeks et al.

Intake, site, and extent of nutrient digestion of lactating cows grazing pasture. This scientist will proceed with objectives 1 and 2 with spectra and analysis supplied by participating Universities, commercial forage testing laboratories, and private research laboratories.

Collecting pasture yield maps from eight commercial dairy farms in Canterbury and the West Coast, with a variety of soil types and irrigation systems, researchers assessed whether the results measured at LUDF were applicable to other farms in the region and found that they were.

New modeling work by an Agricultural Research Service team in University Park, Pennsylvania, suggests that a dairy cow living year-round in the great outdoors may leave a markedly smaller ecological hoofprint than her more sheltered sisters. The rising plate reading must be taken at the set pace interval to avoid bias in the plate meter estimation.

Lasalocid and particle size of corn grain for dairy cows in early lactation. Average net farm greenhouse gas emissions dropped about 10 percent by keeping the herd outdoors year-round. Zur, S. The maximum amount of NDF that should be included in diets is a function of the NED requirement of the cow, the minimum amount of NFC needed for good ruminal fermentation, and the potential negative effects of high NDF on feed intake.

We will initiate grazing when IWG forage reaches inch height at a vegetative stage and graze to a 3-inch height. Destock If available, agistment, or some other arrangement to get animals off the property, is an attractive option.

Hoover and Stokes regressed data from Nocek and Russell and found that when dietary NFC was greater than 45 to 50 percent or less than 25 to 30 percent, milk produc- tion was decreased.
