Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety. One of the regulation systems includes the short chain fatty acids produced during feed degradation in the rumen. Starch can be digested either in the rumen where short chain fatty …
… lead to shorter wool fibres but a denser wool coat and consequently a higher yield. The environment in which the Merino crossbreds were kept also affected wool quality. The animals should be kept under roof before shearing, and straw should not be spread over them.
… one for cleaning (pre-commercial thinning) and one for thinning. The first one yields stem density distributed over diameter classes. In the second one, (the thinning model), it is possible to choose when thinning should be done, the thinning method, thinning grade and numbers …

… and fertilization requirements, by means of determining the stand growth and yield in the Flakmossen trial. The forest growth did not differ significantly between the drainage intensities tested when the same amount of phosphor and potassium fertilizer was added. Thus, shorter …

… welfare value is bigger then the economic result from a forestry whit normal yield. It is stated that taking care of the public welfare in the reserve, is depending on the owners purpose. A public owner’s purpose is better suited, than a private, to take care of the total public …

… 4 is very good if you see to dieselexpenses and hours of work, but the yield is far to low. If the numbers are further analized, it showes that in spring barley the differense between Alternative 2 and Alternative 4 is at a minimum. So if there is lack of time for one reason or …
Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and …
… high salt content in the vicinity of the seed, which can result in lower yields. In this work, we evaluated the Tume Nova Combi combi-drilling method and compared it with the conventional combi-drilling method in the form of Väderstad Rapid. The work comprised three …
… trees in the shelterwood. They react with a higher relative growth and yield a better value increment. Since co-dominant trees tend to be less resistant to wind throw, at least when no preparative cut has been done, this demands that the trees are ca-pable to withstand the …

… plain, were situated on nutrient-rich clay soil. Even the cabbage patch whose yield was an important source of food could be planted in clay soil. Utilizing the space that was available was of vital importance. Favorable conditions provided by sun, weather and wind were taken …
… is planted on poor Scotch pine (Pinus Silvestries) sites and if it affects the yield of Norway spruce? In order to investigate this, data from 29 stands witch had a lower site index than T24 was collected. The investigated stands were situated in the southern-eastern Sweden. In …
… out at Testlab at Ltu, and the tests showed that VascoMax had the highest yield strength and tensile strength, 2030 resp. 2070 MPa. After that followed THG2000 at 1410 and 1590 MPa, 2244 at 1160 and 1390 MPa, 2511 at 900 and 1170 MPa. The PM steels behaved brittle and did not …
… advantages are gained. The component count is decreased by up to48 % and the yield increases by up to 2.9 % which in all yields a costreduction by up to 43 % or ?390 000 for 100 000 manufactured units. Thetime needed for the design process is shortened compared to …
… A discussion of various modifications and additions to the design, that may yield a performance improvement, is also included.
… is the bulk density divided by the basic density. The model has proved to yield good results, despite a relatively small amount of data. A theoretical value of the amount of produced pulp has been computed based on the revolutions of the production screw that feeds chips into …
