“…The range was large similarly to digestibility determinants from 5.31 to 7.24 MJ kg -1 DM. This is comparable with Barrière et al (2003) who measured the content of NEL in the range 5.82-6.95 MJ kg -1 DM. Prediction of NEL from datasets of chemical parameters (Petrikovič et al, 2000) is often more attributed to DM content than to reality of in vivo degradability of organic nutrients (Vencl, 1990).…”

“…Degradation of hemicelluloses and partially lignin during extraction is the major drawback of crude fibre analysis (Huhtanen et al, 2006). NDF content presented cell walls of whole plant maize silage consisted of structural polysaccharides and lignins observed in content 384.1-414.6 g kg -1 DM (Argilier et al, 1998) and 357.0-451.0 g kg -1 DM (Barrière et al, 2003) of maize hybrids harvested at DM 300 g kg -1 . This fraction was markedly variable due to other than environmental factors as the differences in DINAG among tested hybrids are huge.…”

The effect of locality on nutritive value of maize silage with various FAO number was evaluated. There were 8 maize silage hybrids (FAO 220, FAO 230, FAO 260, FAO 280, FAO 390, FAO 450, FAO 550) grown in two similar localities. All 16 groups were cut at milk-wax stage for whole plant silage and ensiled for 1 month in 4 dm 3 glasses. Silages were sampled and analyzed for crude protein, NDF, ADL, Starch and IVDMD. There were found significant differences (P <0.05) between localities within the type of hybrid in crude protein content of FAO 280, FAO 360, FAO 450, in ADL content of FAO 230, in NEL content of FAO 280, in DINAG of FAO 230 and FAO 280. When compared all groups, IVDMD of the silage from FAO 450 grown in locality 2 has been found significantly higher (P <0.01) than all silages of locality 1, except FAO 550. Calculated content of NEL 7.24 MJ kg-1 and value of DINAG 46.8 for FAO 450 were the highest in the experiment.

“…This decrease in cell wall digestibility resulted in a concomitant decrease in a silage energy value of nearly 0.7 MJ/kg silage DM in dairy cow diets (Barrière et al, 2003a). This decrease in cell wall digestibility resulted in a concomitant decrease in a silage energy value of nearly 0.7 MJ/kg silage DM in dairy cow diets (Barrière et al, 2003a).…”

This decrease in cell wall digestibility resulted in a concomitant decrease in a silage energy value of nearly 0.7 MJ/kg silage DM in dairy cow diets (Barrière et al, 2003a). This resulted in the need for supplemental feed, corresponding to nearly 1 kg of grain maize per cow per day.…”

QTL for cell wall digestibility related traits were investigated in maize (Zea mays L.) topcross experiments of 240 RILs obtained from the F838 × F286 early maize hybrid. Genotype effects were highly significant for all agronomic and cell wall related traits and much higher than genotype × environment (GE) interaction effects for cell wall digestibility traits. Eight quantitative trait loci (QTL) for dry matter (DM) yield were observed, out of which only one increasing allele originated from F286. Conversely, three QTL out of four with alleles increasing DM content at silage harvest stage originated from the earliest F286 line. Out of four QTL increasing starch content, two QTL, which originated from F838, did not colocalize with silking date QTL or any other investigated traits. Ten QTL were observed for lignin content and between six and nine QTL were observed for each of the three cell wall digestibility investigated traits. QTL located in bins 1.02 (position 76–80 cM), 1.07 (position 228–230 cM), and 8.07 (position 134–142 cM) are likely of priority interest when it comes to improving maize cell wall digestibility. Candidate genes underlying cell wall digestibility QTL were searched for on the basis of in silico investigations and with maize, Arabidopsis, poplar, and eucalyptus genomic information. In most of QTL positions, transcription factors regulating cell wall lignification were shown to be the currently most plausible candidates involved in genetic variation of maize cell wall digestibility.

“…Besides the physical form of maize kernels, there are differences in rumen digestibility due to maize cultivars. Variation in digestibility among cultivars is mostly related to degradation of plant cell wall and their breakableness susceptibility (Barriere et al, 2003(Barriere et al, , 2004.…”

This research determined the extent of ruminal degradation of a transgenic protein (Cry1Ab) expressed in kernels of maize (Zea mays) cultivar DKC53-32. Cracked kernels of transgenic maize (Bt+) were subjected to rumen digestion using in situ experiments with two ruminally cannulated Holstein cows. A non-transgenic maize cultivar (Bt-) was used as a control for crude protein (CP) degradation. CP and Cry1A concentrations from dacron polyester bags inserted in the rumen were determined for 48 h. The Bt-cultivar had greater CP content (P<0.05) than the Bt+ maize, but no difference (P>0.05) was found in ruminal degradable protein and the CP rate of degradation. The Cry1Ab protein was detected throughout ruminal digestion. The amount of Cry1Ab protein remaining after 16 and 24 h of ruminal degradation was 85 and 60%, respectively. These results indicated that a significant fraction of Cry1Ab protein was not digested in the rumen. This is the first report of the rumen degradation rate of a transgenic protein.
