“…In this study, the digestibility of maize varied little between harvests, which is in agreement with the findings of other authors (Andrieu and Demarquilly, 1974;De Brabander et al, 1986). At both locations, the digestibility of maize was higher than that of sunfiower and sudan-type crops, whose quality decreased with advancing maturity, as reported elsewhere (Demarquilly and Andrieu, 1972;Farhoomand and Wedin, 1968).…”

Forage production based on summer annual crops is a common agricultural practice in many areas of the world where the growing season is favourable.An investigation was conducted over 3 years to compare the dry matter (DM) yield and quality of four annual crops; maize {Zea mays L.), sunflower (Helianthus annus L.), sudangrass (Sorghum bicolor L. Moensch) and sorghum (Sorghum bicolor L. Moensch) x sudangrass; in two rainfed locations with different summer temperatures in north-west

“…The average NDF in vivo digestibility (NDFD) of hybrids was 52.7%, and ranged from 47.5 to 57.1% (NDFD of one bm3 hybrid was also 65.1%). Andrieu and Demarquilly [7] reported an OMD in maize silage equal to 71% that could reach 74%, according to cropping conditions, maturity and/or grain content. The NDFD of hybrids involved in this French study was later estimated to 53.1%, and ranged from 49.8 to 54.8% [27].…”

-Forage plants are the basis of ruminant nutrition, and cell wall digestibility is the limiting factor of their feeding value. Cell wall digestibility is therefore "the" target for improving the feeding value of forage crops. Among annual forages, maize cropped for silage making is the most widely used, and much research in genetics, physiology and molecular biology of annual forages is devoted to maize. Sorghum, immature small grain cereals and straws of small grain cereals are also given to cattle. Some dicotyledons are or were also used, such as forage beets, kales, canola in temperate areas and amaranths in tropical and subtropical areas. Large genetic variation for cell wall digestibility was proved from both in vivo and in vitro experiments in numerous species. Among the regular maize hybrids (excluding brown-midrib ones), the NDF in vivo digestibility nearly doubled from 32.9 to 60.1%. Correlations between in vivo and in vitro estimates of cell wall digestibility were often close to 0.75, but in vitro estimates of cell wall digestibility significantly reduced the range of variation between genotypes. Despite lignin content is well known as the major factor making cell wall undigestible, breeding for a higher digestibility of plant only from a lignin content trait appeared impossible. Correlations between lignin content and cell wall digestibility were indeed greatly variable according to the genetic background. Moreover, enzymatic solubilities were excessively dependent on lignin, and correlation between in vivo estimates of cell wall digestibility and lignin content were always lower than correlation between in vitro estimates of cell wall digestibility and lignin content. Among brown-midrib genes, the bm3 mutant in maize, and the bmr12 (and possibly bmr18) mutant in sorghum, which are both altered in the COMT activity, appeared as the most efficient in cell wall digestibility improvement. Moreover, a great genetic variation in the efficiency of the maize bm3 gene for cell wall digestibility improvement was observed according to the genetic background, with a lower efficiency when the normal germplasm was of better cell wall digestibility. Efficient breeding maize and others annual forage plants demands a renewing of genetic resources. Because resources of interest in cell wall digestibility improvement could be of poor agronomic value, the best is likely to cell wall digestibility / ingestibility / annual forage / maize / genetic variation / breeding / lignin Résumé -Amélioration de la digestibilité des parois des fourrages annuels. Les plantes fourragères sont à la base de l'alimentation des ruminants, mais leur valeur nutritive est limitée par la digestibilité variable des parois végétales, dont l'amélioration est alors la cible essentielle des programmes de sé-lection. Parmi les fourrages annuels, le maïs est la plante la plus cultivée, et c'est sur cette espèce que porte l'essentiel de la recherche en génétique, physiologie et biologie moléculaire. Toutefois, le sorgho, les céréales à paill...
