ABSTRACT A nitrogen balance test was performed to evaluate the individual responses of growing pigs to threonine intake. Eight commercial barrows were used (body weight ranging from 15 to 20 kg). A dose-response study was performed, in which the threonine supply increased in seven equidistant steps (the seven dietary threonine levels ranged from 50 to 120% of the requirements) every three days for each pig. The levels of all other amino acids were 20% higher than the tested amino acid. […]

This study was carried out to evaluate a collection of 53 accessions of Paspalum nicorae, introduced in two physiographically distinct regions over two years, with the objective of characterizing production and quality of forage of access for subsequent phases of a forage plant breeding program. The accessions were established in lines in randomized block design with three replications and the evaluations were performed from October 2007 to February 2009 by using cuts. There was variation of forage production among access […]

This work aimed to evaluate morphological features of the white clover core collection obtained from the United States Department of Agriculture (USDA), represented by 78 accessions, in order to characterize the existent morphological variability and to estimate the genetic divergence, using nine characters (eight morphological and one agronomic). Seventeen plants from each access were evaluated individually at the Experimental Station of the Universidade Federal do Rio Grande do Sul in Eldorado do Sul and characterized in relation to the following […]
