“…No significant differences in CA considering management system, years and mineral N fertilising could be confirmed (Tables 3 and 4). This is similar with results of Peers and Taylor (1977) and Valaja et al (1997), but not with findings of Jørgensen et al (1999) who found significant decrease in the CA content with increased mineral N rates.…”

“…Even more, each mineral N rate significantly increased CP content (Table 5). The same results were obtained in the experiment of Èeh Brenik and Tajnek (2000), Peers and Taylor (1977), and by many others authors, in the experiment of Valaja et al (1997) higher mineral N rate caused higher CP content. Although the protein content was increasing with increased mineral N rate from 9.214.2% (Table 5) (by 35%) ME content and NEL content did not differ considering mineral N rate (Table 3).…”

“…In the first year there was on average 791g of NFE per kg DM of barley grain, in the second season 766g. Increasing mineral N fertilising rate lowered the NFE content (Table 11), that was true in the experiment of Peers and Taylor (1977), and with one exception (one variety of three on one mould type of soil) in the experiment of Valaja et al (1997).…”

“…Nitrogen (N) fertiliser supply increased the crude protein content of grain respectively digestible crude protein content of barley and lowered the lysine content in the protein in the experiments of Valaja et al (1997), Fuller et al (1989), Thomke (1970Thomke ( , 1976 and others. However, usually the reduced amount of lysine in protein is so slight that the total content of lysine in grain increases due to higher protein content (Thomke 1970).…”

“…In many parts of the world, it forms the main concentrate in the diets for pigs and ruminants (McDonald et al 1995). Many factors, most notably climate, soil, genotype and fertilising, can influence its composition and nutritive value (Stekar and Stibilj 1989, Metayer et al 1993, Valaja et al 1997. As a result of variation in chemical composition, barley varies widely in bioavailable energy values (Zhang et al 1994).…”

Many factors, most notably climate, soil, genotype and fertilising, can influence barley grain composition and its nutritive value. The aim of the research was to evaluate the impact of mineral N rate in different management systems in the static long-term experiment with three years field rotation of grain maize, wheat and barley on the chemical composition of winter barley and its nutritive value for ruminants. Crude protein content and metabolizable crude protein content were increasing with increased mineral N rates. Higher yield meant lower crude protein and metabolizable crude protein content in all mineral N rates. The average crude protein content of barley grain, presented in DLG tables (1997), which is 12.4%, was in MM and SM reached by fertilising rate 110 kg N.ha -1 . A significant impact of mineral N fertilising on crude ash, ether extract and crude fibre content could not be confirmed, nitrogen-free extract content was decreasing with increased mineral N rates. A significant impact of the management system on the Weende analysis parameters, net energy for lactation, metabolizable energy and metabolizable crude protein could not be confirmed. At both analyses a significant impact of the season was confirmed on crude protein content and nitrogen-free extract content. Although the protein content was increasing with increased mineral N rate from 9.2-14.2% (for 35%) ME content and NEL content did not significantly differ considering mineral N rate; ME.ha -1 and NEL.ha -1 increasing with increased mineral N rates was the result of the yield increasing with increased mineral N rates.

Variety and location of production can affect the nutritive value of barley grain (Valaja et al 1997). Riviera and Dandy are the most commonly produced varieties of barley in Northern Ireland and it was an aim of this study to compare their nutritive value and to examine the effect of location of production. The growing and harvesting conditions have been shown to affect chemical and physical properties of cereal grain (Rogel et al 1987). A further aim was therefore to compare the nutritive value of Riviera and Dandy produced in 1998 (McCann et al 2000) and in 1999.
